I only see one rare thing in the buildPath. It only contains this:
I have read another posts with this problem but i dont know why does not works if the build path contains the projects.
All helps are welcome. Thanks.

Android - Is there any reason why my app should crash when I add a sound file to raw?

My app crashes when I try to open in. The only change I've made was adding a .ogg file to my res/raw directory. It's really weird. I haven't added any codes or made any other changes. I just dragged a sound file into raw and compiled. It just keeps saying "unfortunately blah has stopped". Are there any obvious things I should check?
MainActivity.onCreate:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.engine_layout);
myEngineView = (EngineView) findViewById(R.id.engineviewid);
myEngineView.setKeepScreenOn(true);
}
I get this in logcat:

Your manifest file has wrong package name when starting the main activity. Replace
android:name="com.signalatrength.gsmece.MainActivity"
with
android:name="com.signalstrength.gsmece.MainActivity"

You can't call getSystemServices until onCreate is called. Move the lines where you get a TelephonyManager and those that rely on it into onCreate

the ClassNotFoundException is usually caused when you try to run your app on lower sdk version than the target sdk

Add your HelloActivity in Manifest file.Due to this your Activity is not found and you are getting ClassNotFoundException as
E/AndroidRuntime(277): Caused by: java.lang.ClassNotFoundException: com.exampe.helloww.HelloActivity

Help with app, (force close)

I created an app, on eclips, but when i try to run it is force close why?

It looks like the class com.soundboard.Jaribarh.LIL_SIDDI/.Jaribarh_soundbord doesn't exist. Possibly a misspelling of soundboard?

This is the important line from your log:
java.lang.ClassNotFoundException: com.soundboard.Jaribarh.LIL_SIDDI.Jaribarh_soundbord
Is there a typo in the class name, or is it possible that this Activity is not declared in the Manifest?
