How to Force Close an App on an Android Phone
Sometimes, apps that misbehave let you know. You see a warning on the Android phone screen announcing the app’s stubborn disposition. Touch the Force Close button to shut down the errant app.
When you see no warning or an app appears to be unduly obstinate, you can shut ’er down the manual way, by following these steps:
At the Home screen, press the Menu soft button.
Choose Settings, and then choose Applications.
Choose Manage Applications.
Touch the Running tab at the top of the Manage Applications screen.
Choose the application that’s causing you distress.
For example, a program might not start or might say that it’s busy or has another issue.
Touch either the Stop or Force Stop button.
The program stops.
After stopping the program, try opening it again to see whether it works. If the program continues to run amok, contact its developer: Open the Market app, press the Menu soft button, and choose My Apps. Open the app you’re having trouble with, and choose the option Send Email. Send the developer a message describing the problem.
