An Android app may close because of a bad update, low free storage, corrupted temporary data, an operating-system problem or a service outage. If several unrelated apps fail, the cause is probably not one app.
Short answer: Restart, update the app and Android, free storage, then clear only the affected app cache before considering reinstalling.
Check the likely cause first
- Note whether one app or many apps close and whether the failure began after an update.
- Check free storage and install pending Google Play system and Android updates.
- Open the app on Wi-Fi and mobile data if it depends on an online service.
Fix it in the safest order
- Restart the phone and try the exact action again.
- Update the affected app from its official store listing and update the operating system.
- Open Settings, Apps, the affected app, Storage, then clear cache; menu names vary by manufacturer.
- Back up app data and account recovery options before clearing storage or reinstalling, because local saves may be erased.
Change one thing at a time and retest. That makes it easier to identify the cause and undo a setting if the result is worse.
How to confirm the fix
Repeat the action that caused the crash several times. If the app stays open, avoid restoring battery cleaners or overlays until they have been ruled out.
What not to do
- Do not install an older APK from an unknown mirror.
- Do not clear app storage before confirming that progress and sign-in recovery are protected.
When to contact support
Contact the developer with the phone model, Android version, app version and reproduction steps if only that app continues to fail.
