A great number of owners of Android devices faced errors in applications: they can either not open at all or function incorrectly. This, of course, is unpleasant, but each error has its causes and solutions. In this article, we will find out why Android applications do not open and how to fix it.
Android applications market is growing faster than ever. Such a rapid development has a downside – a great variety of devices and a huge number of developers from time to time leads to the fact that the applications are incompatible with some of the devices, though developers try to minimize such cases.
Also, there are other reasons why Android application won’t open:
If you installed the application from the official Google Play Store, it means it has been tested and is suitable for your device. Otherwise, in place of “install” button, there will be a note that the application is not supported by your device, and you will not be able to download it. If you have downloaded the installer file apk and installed the application yourself, then there is no guarantee that the application is compatible with your device and can work correctly or even start.
Each program for Android has the technical requirements and a certain amount of RAM is always required to run it. If there’s not enough RAM, the application may not start simply because there may be no enough resources. The easiest solution to this problem is to close background applications and clear the required space in the RAM. We discussed how to do this in our article How to disable background applications.
Also, there is a more difficult way – create a page file on your SD card using special applications such as ROEHSOFT SWAPit RAM EXPANDER. The application allocates space on the memory card and uses it to increase the volume of RAM. You need to understand that the speed of the RAM is higher than that of the memory card. Using the paging file, you can run the heavier applications or keep more apps in the background for multitasking, but it will affect the speed and stability of the device. Unfortunately, this solution is not supported by all smartphones. Before installation, check whether your smartphone supports the swap function using the utility MemoryInfo & Swapfile Check, after checking it can be deleted.
To enable the paging file, open the app ROEHSOFT SWAPit RAM EXPANDER and press “Activate swap”. Below you can choose the size of the swap file, exactly as much amount of additional RAM will be available. The maximum size of this file is 4000 Mb, this is a limitation of the system.
A large number of applications are being developed for the latest version of Android operating system, so the system should be updated to the latest available version at every opportunity. To find out whether there are any updates for your Smartphone, open phone settings and select the section “About phone”. In the bottom section that appears, click “System update” and check for updates. If there are updates, install them.
It is not possible to update Android this way on all devices, in some cases, you will need to check for updates on your smartphone developer’s site and install them connecting your smartphone to the PC.
If the application worked properly first, but at some point, it stopped running or started closing by itself, it is most likely that an error occurred in the application itself. First of all, try to restart it. It is not enough just to close the application clicking “Home”, it will continue to run in the background. You need to go to the device settings, select “Applications”, click on the necessary one and close it. If that did not work, you either need to clear the cache and application data, or reinstall it.
