“Unfortunately, the app has stopped.” You reopen it, it dies again, and the only advice anyone gives is to clear the app’s data — which throws away your chats, your saved game, or your login.
Clearing data almost always works. It is also the last thing you should try, not the first. Here is the order that fixes most crashes without costing you anything, and what to back up if you do end up at the bottom of the list.
1. Force stop it, then open it again
Settings → Apps → see all apps → the app → Force stop.
Swiping an app off the recents screen does not always end its process. A force stop does. If the crash came from a confused process rather than a real fault, this is the whole fix, and it takes ten seconds.
2. Restart the phone
Obvious, ignored, and genuinely effective. A phone that has been up for three weeks accumulates stuck processes and exhausted memory. Restart it properly — power off and on, not just the screen.
3. Clear the cache — not the data
Settings → Apps → the app → Storage & cache → Clear cache.
The cache is files the app can rebuild by itself: thumbnails, downloaded images, temporary working files. Deleting it costs you nothing except a slightly slower first launch. A corrupted cache file is one of the most common causes of an app that starts and immediately dies.
Do not touch “Clear storage” or “Clear data” yet. That is the button that wipes your account, your settings and your local content.
4. Update the app
Play Store → your profile picture → Manage apps & device → Updates available.
If the app started crashing on a day you did nothing, the probable cause is a bad release — and the probable fix is the release after it, which may already be waiting.
5. Update Android System WebView and Play Services
This is the step people skip, and it is the one that explains the strangest crashes.
A great many Android apps do not draw all their own screens. They use a shared component called Android System WebView to display web content inside the app. When WebView is broken, every app that relies on it crashes at once — and it looks like several unrelated apps all failing on the same morning. This has happened at scale before, and it is worth ruling out first whenever more than one app is misbehaving.
In the Play Store, search for Android System WebView and update it. Do the same for Google Play Services. Then restart the phone.
If several apps are crashing and one app is not, this step is almost certainly your answer.
6. Check the phone is not out of storage
An app with nowhere to write its temporary files crashes rather than explaining itself. Settings → Storage. If you are under about a gigabyte free, apps start failing in ways that look like bugs but are not.
7. Check its permissions
Settings → Apps → the app → Permissions.
An app denied something it assumes it has — storage, camera, microphone — can crash instead of handling the refusal gracefully. Badly written apps do this constantly. Grant what the app genuinely needs for what you are doing, and nothing beyond it.
8. Test in Safe Mode
Safe Mode starts Android with only the apps that shipped with the phone. If your app works in Safe Mode and crashes normally, something else you installed is interfering with it.
On most phones: press and hold the power button, then press and hold Power off on screen until “Reboot to safe mode” appears.
The usual culprits are screen-overlay apps — blue-light filters, floating chat heads, screen recorders and cleaner apps that draw over other windows. Uninstall those one at a time. Restart normally to leave Safe Mode.
9. Uninstall the app’s updates
For an app that came with the phone, there is a middle option between clearing the cache and wiping everything.
Settings → Apps → the app → three dots (top right) → Uninstall updates. The app drops to its factory version, keeping your data. If a recent update was the problem, this proves it.
10. Last: clear the data — but back up first
If you get this far, clearing the app’s data will almost certainly work. It will also wipe what is in the app, so spend five minutes protecting it:
- WhatsApp: run a chat backup and confirm it finished before you clear anything. Do not take “it backs up every night” on trust — open the backup screen and look at the date.
- Games: link the account to Google Play Games, Facebook or the game’s own login. A local-only save is gone for good.
- Banking and authenticator apps: do not clear data until you know how you will get back in. An authenticator app whose data you wipe can lock you out of everything it protects. Check you have recovery codes first.
- Anything else: export whatever it lets you export.
Then: Settings → Apps → the app → Storage & cache → Clear storage → reopen and sign in.
If it still crashes after clearing data
Then the fault is not your copy of the app, and no amount of work on your phone will fix it. At that point the useful moves are:
- Check whether other people are reporting the same thing — the Play Store reviews from the last few days usually say so plainly.
- Check whether your Android version is still supported by the app. An app that dropped support for older releases will crash on launch and never explain why.
- Write to the developer with your phone model, Android version and app version. Without those three, a report cannot be acted on.
The short version
- Force stop, reopen.
- Restart the phone.
- Clear the cache.
- Update the app.
- Update Android System WebView and Play Services — especially if several apps are crashing.
- Make sure there is free storage.
- Check permissions.
- Test in Safe Mode for overlay apps.
- Uninstall updates.
- Back up, then clear data.
