To fully use a gadget with Android OS, you need to install various applications on it that will help you comfortably watch videos, process photos, communicate on social networks, etc.
Usually everything goes fine, but sometimes it is not possible to install a game or application. Why is this happening?
Most common cause: random failure
Any technique is not immune from accidental failure. If the installation failed for the first time, most likely this is an accidental malfunction. Just turn off the phone (tablet), and then turn it back on, i.e. reboot your device.
As a rule, this is enough for everything to work fine the next time you start the installation.
Out of memory
Downloading applications on Android devices always occurs only in, and not on a memory card. After installation, some of them can be copied to the card, but not all. If your device's own memory is full, or the app you're downloading is taking up a lot of storage space, you'll need to free up space for it to install.
- Check the free internal memory of your tablet or smartphone.
- Browse the list installed applications, remove the ones you no longer use.
- Transfer files to the memory card for which Android allows this action. Usually these are photos, video and audio files, texts, etc.
- Run the program to clean up memory from garbage - temporary files left after the work of applications. If cleaning has not been carried out for a long time, then a sufficiently large amount of memory can be freed after it.
After completing all these operations, try downloading the application you need again. If there is a lot of free space, then it should install without problems.
Unlicensed or incorrect application
Check the source from where you want to install the app. Many gadgets today are used with the installation of antivirus programs and other security systems. If the application being installed is incompatible with the official version of the Android OS or contains viruses, it will not be installed. The Android OS developer recommends using only applications from the Play Market for installation, since their safe and correct work he can guarantee.
If you still want to install the application from another source, go to the security settings and allow the installation of third-party software. It is possible that in this case it will be downloaded to the memory of your Android device as a file, and then you will have to run it with a special installer. But in this case, no one can guarantee that it will work correctly on your device and will not conflict with other applications.
Reset
In the case when all of the above did not help, or if, after various attempts to change the settings, Android almost stopped working altogether, the last resort remains - resetting the settings to the original ones. Before starting a factory reset, remove the memory card and try to save your contact list and other important information on your desktop computer.
Remember that after a factory reset, all personal information will be deleted from the device's memory. But after the phone's memory is cleaned in a radical way, you will most likely be able to install the application you need there without any problems.
The Android operating system is useful in that it has an official application store, thanks to which millions of users do not need to search for a particular program on the network. You can install millions of apps from an official, updated and moderated source for free. However, even here difficulties can arise. Therefore, in this review, we will analyze in detail the solution to the “Application not installed” error. It is not critical, so if you saw it for the first time, do not panic.
System junk and its cleaning
First of all, if your operating system generated a similar error, then this means that it is necessary to clean the memory from system garbage. It appears as a result of running applications and saving the cache. All temporary files are stored in internal memory and in large quantities. The lack of this memory can be the main cause of failure. For cleaning, we will use the Clean Master utility. Any self-respecting user should install it among the first applications when buying an Android device.
How is the cleaning done?
- The application is launched;
- All garbage is analyzed and sorted into categories;
- After confirmation, it is cleared;
- Also, by pressing, you can close all applications running in background so as not to load the RAM once again;
After completing these steps, restart your gadget. Next, go to Play market and try to install the necessary application again. This method helps in 95% of cases. Clean up regularly, especially when you start to notice app crashes or operating system generally.
Instead of the Clean Master recommended by us, you can use any other utility. They all work on the same principle. The advantage of Clean Master is that it is absolutely free. You can also combine utilities with antivirus programs to achieve a greater effect (of course, if your device allows the use of two similar programs in the background and will not be heavily loaded).
Removing unnecessary files and applications
If you encounter an "Application not installed" error, you You can also try deleting all unnecessary data from the phone. This is especially true for old and unused applications, photos and other things. Statistics say that errors begin to appear already when the free space becomes less than 500 megabytes.
Do not store music, movies, and video files on the internal storage. Firstly, this is an extra risk of losing data forever. Secondly, it loads your smartphone quite well, slowing down its performance. Transfer them to HDD computer, cloud or SD card and clean up system junk.
Moving data to a memory card
If you have nothing to delete from the internal drive, then you can always transfer part of the load and data to a memory card. This action can be done using standard applications that are present in all systems. Of course, this slightly reduces the performance of the applications themselves, but increases the performance of the system as a whole.
Some devices may not allow such data transfer, or may not have any additional SD card slots at all, keep this in mind.
Reboot
Rebooting has always solved over 70% of the problems of all users. Perhaps you forgot about the most banal way to correct errors. Perform a Reset, then return to the Play Market and try downloading the application again.
Virus cleaning
Install some free and simple antivirus immediately after purchasing the phone. This will save you from 90% of problems, as well as annoying ads that can pop up even without using any applications.
If you have started your device so much that none of the above actions will help it, then follow hard reset system, after saving all important data on external drive. This will help you reset your phone to factory settings.
Imagine the situation: you want to install on your tablet or phone on the OS android new game or Viber messenger, but the download or installation does not occur. The application refuses to install, the loading bar seems to take forever, or there is an "out of memory" error at all. The problem is common and easily solved.
There may be several reasons:
- not enough space in the internal memory;
- download failed due to viruses;
- custom unstable firmware is installed on the device;
- Internet connection is not stable;
- not enough mobile internet traffic.
As with many other crashes, the problem can be fixed by restarting the device. But not all problems can be solved by rebooting or resetting to factory settings.
We are not responsible for your actions. We recommend that you contact the service center for a solution to the problem.
Out of memory
When applications are downloaded from the Play Market, they are downloaded exclusively to the internal memory of the device. It will not work to select a memory card for downloading, you can only transfer the installed one in the future (and even then not every one). Cards are considered by the system as unreliable, because many problems can arise due to damage or failure. There is nothing you can do to ensure that applications are installed on the memory card by default. Therefore, the internal memory will have to be cleaned:
- uninstall apps you don't use;
- transfer music, photos and videos to a memory card;
- delete all unnecessary files, clean up temporary and garbage special utility;
- clear the cache of applications, first of all the Play Market.
Some applications (from those already installed!) can be transferred to microSD card. To do this, you need to go to the "applications" tab in the settings menu and transfer them to an external drive manually. When the memory is freed and there is enough space to install a new application, you can try downloading again.
Viruses or firmware
If there is enough space, the cache is cleared, and applications are not installed on Android, the reason may lie in the infection of the device with viruses. If the antivirus is already installed, just run it and then fix the infected files or remove them completely. But the antivirus is also an application, if it is not worth it, you will have to install it manually.
Try downloading the apk from a trusted site and then installing it. If not, it is recommended to reset the system to factory settings. Problem not solved? It is worth contacting the specialists in the service center.
Also, the problem may be software failures associated with the firmware. Custom firmware sin with errors and the most unpredictable bugs. There's a good chance you've installed one. There is only one solution: flash the device to a stable official version suitable for your device on the Android operating system.
Unstable Internet
It does not matter where applications are installed and how much free space is available if you have an unstable Internet connection that does not allow you to download even the easiest program. It's best to download and update everything when stable WiFi connection. Through 3G Internet, failures may occur due to disconnections. If you are seeing an "eternal" download bar, delay the download and installation until a normal connection.
How to install applications through the Play Market and directly
Most applications can be found in the Play Market. Go to the page you want, click on the "install" button. After that (with a stable Internet connection and the presence of free internal memory space), the download will begin. Direct installation starts only after you confirm it by setting the appropriate permissions for the application. Everything is simple and intuitive.
But if desired application No? Or is it not available in your region? There is a need to learn how to install the application on Android directly, and not from the online store. Official developers often retain the ability to directly download the application from their website or blog. So Flash Player can be found on the Adobe website without looking for it in the Play Market. The main thing is to download applications only from trusted sources, ignoring dubious sites.
Find the application, download the .apk file to the device, then find it in memory. And just run. The program will ask for the necessary permissions, and then begin to install. In the same way as with the installation from the Play Store. Yes, the same apk file is downloaded from there. Just starting automatic installation after download. By downloading the application directly, you can install it at any time.
A common error in the Android operating system “The application is not installed” is not at all a reason to panic. After all, we have a universal tool - this is a reboot. It allows you to get rid of more than 50% of all errors that occur. The statement is equally true for computers and smartphones. If the reboot did not help, we will proceed differently.
The error "The application is not installed" may appear as a result of an elementary overflow of user memory. Once it was enough to have 4 GB on board, today even 32 may seem a little. To clear the memory, delete unnecessary photos - these may be duplicates, corrupted pictures already posted on the Photo Network. If it's a pity to delete, move them to cloud storage- the same Yandex gives 10 GB of disk space. Also, files can be moved to a memory card - subject to the availability of the appropriate slot and the card itself.
In addition to photos, you need to delete other unused files - videos, documents, downloaded music. If you feel sorry for deleting, save them in the cloud or on a memory card. If you use the WhatsApp messenger and you are regularly flooded with videos, do not forget to look in the messenger folder and delete from there unnecessary video- with an active exchange of clips, their total size can be whole gigabytes.
Deep cleaning of user memory is performed using applications like Clean Master. The program distinguishes between duplicate photos, clears the cache, and also provides cleaning random access memory. Additional functionality:
- Checking for viral infections.
- Vulnerability check.
- Phone speed up.
- Cooling the processor by removing unused tasks.
- Advanced memory cleaning.
- Cleaning WhatsApp - this was discussed a little higher.
- Gallery encryption.
It also has many other useful features.
Applications are not installed or the error “Application not installed” appears - run Clean Master, delete junk and unnecessary files with it. After that, try to install the software again.
There are many other programs with similar functionality in the Playmarket app store - try them if Clean Master seems inconvenient.
Antivirus cleaning
Unfortunately, viruses can penetrate the system even if you do not visit dubious resources, do not accept files from other contacts, and use only the Playmarket app store. Experts say that viruses can be present even in the store itself. If you have a problem with the "Application not installed" message, run a virus scan.
Select to scan the system:
- Dr. web light.
- kaspersky mobile antivirus.
- Avast Antivirus & Protection.
- Antivirus from AVG.
Another option is ESET antivirus. MegaFon subscribers using the "Turn on" tariff line can set free version anti-virus software from ESET with the "Anti-theft" function. Put the software you like, allow it access to file system and run a full scan. It will take from several minutes to half an hour, depending on the number of files on your device.
If the scan results show the presence of virus bodies, remove them with an antivirus. Now try to install the application that was giving the error again. To be safe, we recommend that you restart your device.
Send apps to SD card
Sometimes the search for a free place to install applications makes it necessary to remove the necessary programs. What to do in this case? Some Android smartphones support transferring applications to memory cards. Move them to the card and try to install desired program again. Cons of this technique:
- Not every smartphone allows you to transfer programs to memory cards.
- Some programs are not transferable.
- Loading software from the card becomes a little slower.
The last problem is solved by installing a high-class card with a high data read / write speed (for example, class 10 provides a speed of at least 10 Mb / s).
Finding Other Software Sources
The “Application not installed” warning often appears when installing programs downloaded from “left” sources. These are hacked games, as well as software that for some reason is not allowed to be placed on the Playmarket. To install them, you must allow installation from unknown sources - this is done in the security settings of your Android smartphone.
Making changes to the software (including hacking game parameters) leads to the above error. Who and how made the changes is unknown. If the error appears again and again, try to find an alternative source of programs. Another recommendation - read the instructions for installing the software, perhaps there are some subtleties.
Individual incompatibility
There are thousands of Android smartphones. Therefore, there are a lot of software incompatibility problems on this platform. The same one can work on cheap smartphones from little-known companies and be desperately stupid on top flagships. The reverse situation is also possible - the program, tested on proven devices, refuses to be installed on Chinese pipes collected somewhere in the basements.
Even from this difficult situation there are two outputs:
- Try to search the Internet, who decides and how this problem(usually problematic software leads to discussions on specialized forums and resources.
- Write a review to the developers - this is done through the Playmarket. Rate and describe the problem. If developers monitor their software, your problem will be noticed and taken into account. Perhaps it will be removed in the next update.
You can also look for analogues of an application that does not want to be installed on your device.
Reset to factory settings
This measure is taken when nothing else helps. The reset is performed through the settings, all data in the smartphone's memory is deleted. The device is completely returned to the state in which it left the assembly line. Before performing a reset, you need to save important data - SMS, messages from instant messengers, photos and videos, contacts and much more.
None of the smartphone users is immune from problems with installing applications. Almost everyone at least once saw a message on the screen that the program could not be installed. There are several reasons for this failure. Let's figure out why applications on Android are not installed.
Not enough memory
This is the most common situation resulting in application installation failures. There are several options for fixing the error in this case:
- If you have installed many applications and do not use some of them, then you need to. Games take up the most space, so get rid of them first. To do this, go to settings, find "Application Manager". Select a utility that you no longer use, open its menu and click the "Delete" button. To facilitate the search in some devices, the list of programs is divided into parts, you need to work with user or downloaded ones.
- If, due to lack of memory, applications on Android are not installed. The error may be related to an overflowing cache. You can clean it with the help of special utilities. Most smartphone manufacturers include Clean Master in the list of applications, it effectively copes with the "garbage" in the device's memory. If you cannot install special utilities, you will have to clear the cache manually. To do this, go to the "Application Manager" and delete the cache from games, browsers and instant messengers. In most cases this will be sufficient.
- In some cases, even after clearing the memory, you will not be able to install applications, this is due to the exhaustion of the reserve in the internal memory for placing programs. Smartphone memory module provides storage different types data. The limit for applications on it is limited, although the file manager will indicate the availability of free space. In this situation, you need to go to the application manager, and then transfer some of the software to the memory card.
By default, applications are not installed on the Android SD card, to fix this you need to change the memory settings. You need to act through the "Storage" section of the general settings, and then click on the gear or three vertical dots in the upper right corner.
What to do if applications are not installed on the memory card?
When applications are not installed on the memory card even after setting up, you need to check their requirements. Some programs can only be installed on the internal storage. In this case, you need to check the free space on it.
Also, the problem may be a malfunction of the media itself and a lack of its volume. Check the memory card in another device or insert it into a computer.
Scan the drive with . If there is not enough space on the card, delete the extra files. This can be done manually, using and from a computer.
How to fix if apps won't install on Android due to lack of permission
This error most often occurs when installing applications from sites, and not from the official store. In this case it is necessary:
- open the settings menu;
- scroll through the list of options to the "Security" section;
- set a marker in front of the item "Install applications from unknown sources".
In versions 7 and 8 of the operating system, the user requires additional permission to install the application. In version 9, you need to activate the download of programs from alternative sources every time.
Incorrect Application
The occurrence of errors when Android applications are not installed from the Internet is due to the fact that you have chosen a source with a low-quality assembly. The developer could modify the program, but at the same time not include the necessary functions in it. This problem is solved by finding an alternative source for downloading and installing programs.
Incorrect application for the system version
One of the important compatibility parameters software with your device, the version of the operating system. Major manufacturers include support for various android versions, while small companies can only develop a utility for version 4 or 6 of the operating system. The way out can be:
- if applications from the market are not installed on Android, then you need to try to download them from;
- update your operating system;
- ask the developer to include your OS in the list of supported versions.
You can also ask the developer for an assembly for your OS, but only if you are using an outdated program.
Interferes with the application from the phone's memory
Some utilities are incompatible with each other. Most often, the error occurs if you download several antiviruses or file managers at the same time. In this case, you need to decide which program you will work with in the future and leave only it.
There is another kind of this failure - when you incorrectly uninstalled or installed the application, and then try to download it or update it. With such a problem, you need to remove the old application, first. Only then you need to put a new one.
Google services crashes
If the problem occurs only when used to download the Play Market, and utilities are installed from alternative sources without problems, then you need to work with Google services. Go to "Application Manager" through system settings, find . Clear the cache in this app. If this does not help, then you will have to reinstall or update the service department.
System failure
If you have checked everything possible options, but the installation error does not disappear, then the cause may be a failure of the operating system. It is enough to correct the situation with the help of 2 steps:
- reboot the system;
- scan it with an antivirus utility.
In cases where the problem cannot be eliminated by these methods, it is necessary to carry out full reset and system recovery. If the problem arose after changing the firmware of the device, then you will have to carry out this procedure again. best left to the experts service center, then the risk of damaging the smartphone will be lower.
Most often, utilities are not installed on a smartphone for one of the listed reasons, but in some ways the situation can be corrected only by complex measures. Now you know all the ways to solve the problem of installing applications. If you liked the article, share it with your friends. In the comments, you can talk about your problems with downloading smartphone utilities, as well as discuss methods for dealing with these failures.
