Unfortunately app has stopped in Android Emulator

问题:

I am new to Android and I am trying a few small apps (like Compass). When I run the app in the emulator, it gives the message Unfortunately, Compass has Stopped.

I have no compile time errors.

How do I solve this, and what is causing this?

Thanks in advance.

I had the same error message and found that, in commenting out uses-permission nodes in AndroidManifest.xml I had commented out one that was needed. When I put it back in the app ran fine. I was able to reproduce the error. I needed:

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

This was for a barebones index.html, single page app, that displays Hello World. And the permission above was the only one I needed to do Run As/ Android Application and get it to run in an emulator.

HTH

You have posted no code so it's difficult to see what your problem is. However I had the same issue which has been sorted out here Unfortunately HelloListView has stopped

It probably due to the fact that you don't have accelerometer and magnetic field support. Go to your AVD configuration and add the following hardware: Magnetic Field Support and accelerometer

回答4:

First check your AndroidManifest.xml file and write activity tag

For example, you have DisplayMessageActivity.class and package is me.user_interface

tag is:

<activity android:name="me.user_interface.DisplayMessageActivity"/>

You can write this after </activity> tag in AndroidManifest.xml file. Check the path carefully.
