Go to "Settings → Applications → All" in turn, find and click the icon of the APP, select "Clear Data" and "Clear Cache" in the application information interface, and then run the app again.

In addition, if an APP only occasionally gives an error message that "the application stops running", it may be caused by insufficient system memory. Just clean up the background program before running.

There may be network reasons, so I suggest going to a place with a better network environment.
