The app won't open on Android? 10 ways to fix it

Even though Android is considered a less stable operating system than iOS, there is not a single issue that Apple considers a problem and Google considers normal. Even if an application from Google Play - no matter which developer released it - crashes and refuses to work, Google primarily takes the blame. She investigates the causes of this problem and either urgently corrects it or offers a temporary solution. The search giant is doing just fine with this. Another thing is that with the delivery of messages about ways to solve certain problems, Google is doing frankly poorly. It's good that you have us.

Are apps crashing on Android? There is a solution

How to overclock an Android smartphone through the developer menu

This week, Android users began to complain en masse about spontaneous crashes of applications using the Android System WebView. These are mainly mobile email clients, instant messengers and other types of software with built-in browser widgets.

Check Android updates

The opposite problem may also arise. The app may be too new for your current version of Android. Check if there are any pending system updates on your phone. Install them before launching the application again.

To find out if you have any system updates waiting in the wings, drag the app's shadow down and open the settings menu. Then look for Software Update or something similar.

You can use the search function in the settings menu if you do not see the software update menu. You'll see a notification that your phone has the latest version, or that an update is pending.

The phone constantly says that applications are not responding. What to do if your Android app is not responding

In the Play Console, you can view information about application crashes and ANR errors (Application Not Responding). The information comes from Android devices whose users have enabled automatic diagnostic data submission.

Significant data changes (problems) are displayed above the failure data. Problems can only be detected for crash stack traces without obfuscation. To receive notifications about problems in the application, in the upper right corner of the General

select
Notification settings
.

If your app crashes frequently, find a solution to the problem on the Android Developers site.

Check for app updates

It's also possible that your app has been updated by the developer, but you haven't installed the update yet. Open Google Play Store and go to the application page. If an update is pending, you will see an "update" button instead of the usual install or open button.

Alternatively, you can open the Google Play Store, then select your profile icon > My Apps & Games > Updates tab. All applications that require updating will be shown here.

Download an unpublished old version of the application

Reverting to an older version of the app that used to run on your phone may resolve various issues. If new errors have been discovered, you can avoid them by using the old version of the application. If your phone's operating system is too old, the older version of the app may be the last version that will run on your phone.

If your phone's manufacturer isn't going to update to a newer version of Android, you can usually download an older version of the app.

Sideloading is a workaround where you manually copy the APK file into your phone and install it yourself. You need to allow applications from unknown sources to be installed on your phone.

You can usually find the APK file for older versions of this app on sites like APK mirror.

This is only possible if the application in question does not rely on web services. Old versions of an application rarely remain compatible with the latest web services provided by the application manufacturer. These services are usually designed to only work with the latest version of the software. However, for some applications, such as games or standalone utilities that do not require connection to web services, it is possible to install an older version from an APK file.

Reasons for the notification

The Android OS, as well as all operating systems without exception, accumulate useless files (folders with system files from deleted applications) during use. Installing a significant number of applications running in the background plays a role. Android has a hard time when working with background applications: they use a large amount of RAM, and therefore heavily load the processor. If there is a system error on Android, the device software or Android OS does not respond to the actions of running and background applications. The main reasons why the System application does not respond on Android are:

  1. Insufficient RAM.
  2. Application conflicts.
  3. Installing malware from an unknown source.
  4. Incorrect OS update
  5. Clipboard overflow
  6. Low-quality device firmware and much more.

Force close the application

The application may not open because it was never closed. So, force close the application and launch it again.

The exact steps may vary slightly from one brand of Android phone to another and from one operating system version to another. General steps:

  1. Open settings
  1. Open the application, or applications, or application management, or something similar.
  1. Find and select the application.

  1. Select Force Stop, Force Quit, or something similar.

After force closing the app, try opening it again and see if that helps.

Error loading device operating system

This malfunction usually occurs in only two cases. The first and most common: the software developer simply deleted it from the server. Therefore, an error pops up and says that the file was not found. Here you just have to wait until the creator of the program uploads a new and updated version. But if other applications are not installed and the system does not respond when interacting with the Play Market, then we follow the next advice.

After this operation, the problem with the system should be resolved. But if this method fails to get rid of the error with the system, then this means that the firmware is severely damaged, and only a trip to the service center can help. Often this is due to the fact that system files have been damaged, which can only be returned by the device’s firmware.

If the software still does not respond, then just in case it is worth checking whether the time and time zone are set correctly.

If your phone or tablet does not want to boot and displays “the system application is not responding, should you close it?” and the G-sensor stops working, and the screen is in black mode for a long time and only after that the android decides to boot, then only resetting the settings will help here. More precisely, not just a reset, but a so-called hard reset (with all the wipes from the recovery menu).

  1. Go to Explorer (ES Explorer is best).
  2. Open the Tools tab - Task Manager (install the module if necessary).

Having determined that there is a Trojan in the Android OS, you need to remove it. It is likely that a malicious application was loaded on the system before the error appeared. You need to get rid of it first. Find out what the program is by searching for it by installation date. For this:

To configure the date and time manually:

Clear app cache

Many Android apps maintain a local cache of information to help them run more efficiently or when the Internet connection is lost. If this cache is corrupted, it may cause problems with the application.

Check out our article on how to manually clear app cache. Again, the exact steps may vary depending on your Android phone model.

Now restart the application. You may have to re-enter your credentials depending on the application type.

Move the app from the SD card

Some Android phones allow you to install apps or move parts of apps to the SD card. Unfortunately, SD cards are less reliable than your phone's internal memory and can be easily damaged. A damaged SD card may prevent the application from launching.

Try moving the app back to internal storage from the SD card, after which you may have to reinstall the app if any files have become corrupted.

Ways to resolve the error if applications on Android do not respond

If applications on Android do not respond, you need to proceed to troubleshooting steps. To resolve a system error on Android, a number of techniques are recommended:

  1. Reboot your device. Disabling the device will refresh and clear the RAM (random access memory) and restore the device to its nominal functionality.
  2. Remove unnecessary programs. A large number of installed programs loads the processor and uses up RAM.
  3. Optimize the system. By running CCleaner, clear your device of cache and unnecessary system files.
  4. Update recently installed applications. Developers are constantly providing new versions of applications to improve productivity.
  5. Remove the SD card. There may be bad sectors on the card, which affects the performance of the device.
  6. Reset your device to factory settings. When resetting the settings, the RAM is completely cleared and the Android system is reconfigured to the “Default” mode.

The most effective solution is to return the device to factory settings, which will allow you to return to standard functionality. The method is recommended to be used in the latter case, because all user files on the device without exception will be deleted permanently. In order to save contacts, it is better to save everything on the SIM card, and remove the SIM card from the device when resetting the settings.

Uninstall and reinstall the application

If none of the above fixes worked for you, a more drastic step would be to uninstall and reinstall the app. You may lose data for an app you're having problems with. So, see if there is a way to save this data before deleting it. Here's how to do it:

  1. Open the Google Play app.
  2. Select your profile icon.
  3. Select My apps and games.

  1. Select the Installed tab.

  1. Select the problematic application.
  2. Click the Delete button and confirm.

  1. Now click on the “Install” button and wait for the application to finish downloading.

  1. Launch the application again.

Hopefully you will now have a working application again.

Factory reset

    Open Play Market and enter the word “Google” in the search bar.

So, the com.android.systemui process has stopped, what should I do in this case?

If, during the data analysis process, nothing indicated a virus, there was probably a simple error in the system file. The error may not appear again after rebooting the system, so reboot Android first. If this doesn't help, try the following steps in order.

Almost any error in devices running Android can occur due to a failure to automatically detect the time zone or time. You can read more about this in the article “Setting the date and time on Android.”

Remove Webview updates

WebView is an important common component of Android that is used by many applications. When something goes wrong with WebView, it can cause applications to behave incorrectly.

If the latest Webview update is wreaking havoc on your phone, you may actually want to revert to an older version. Here's how to remove Webview updates:

  1. Open the Google Play app.
  2. Find Webview.
  3. Open the application page from the results.

  1. Click the "Delete" button and confirm your choice.

Check if your application is working again. If it works after uninstalling WebView updates, wait until a later update becomes available or the application itself receives an update that fixes the problem. You can then refresh the WebView again using the same step as above, except you will use the Refresh button instead.

First aid

In such cases, it is worth finding out the reason. Try sending the bug directly to the developer and let them resolve your issue. If this option does not suit you because it wastes time, then take the phone to a mobile device repair service.

There is no way to take your gadget to a service center? Are you still wondering about the Settings app? Android not responding? Our article will tell you what to do. First, clear the cache, you can do this through the CleanMaster application, you can download it from Google Play.

Enabling it on each phone individually. You can find the algorithm freely available on the Internet. As soon as you have enabled safe mode, and it sometimes turns on itself due to critical errors in the settings, you need to go to the settings themselves, installed applications and find sms/mms there and click on delete.

They say that a simple reboot can save you from all the troubles of the Android platform. Try turning off and on the phone, and if this does not help, and you are still wondering “the setting application is not responding, android, what to do,” then other actions will be required.
