There are 5 common ways to fix the error:
1. Re-install the app
First, uninstall the app that is causing the problem and then re-install it.
2. Uninstall newly installed apps
Sometimes newly installed apps don't support the software or hardware of the device and thus they should be removed from the device to get rid of the errors caused by the app itself.
3. Clear cache
Cache files are the main source of errors and problems in the functioning of Apps, clearing the cache may solve most of the problems associated with Apps. To clear cache, go to Settings > Application > Manage apps > Select "All" tabs, select the app which was producing error and then tap Clear cache and data.
4. Clear RAM
Clearing RAM is a good deal when you are facing the error "Unfortunately, the app has stopped" in Android. Apps running in background use plenty of RAM and thus there is less RAM available for the app usage hence producing the error. Go to Task Manager> RAM> Clear Memory.
5. Factory Reset
If none of the methods above worked, you have to factory reset your device. Back up your device before a Factory Reset as it will erase all the data related to apps, all software updates, even your pictures, documents, messages, contacts and any personal files saved to the Android memory storage.
