android floating view bubble

Question

ich baue eine app für android mit android studio, und wenn ich die app direkt auf meinem handy laufen, stürzt es ab, wenn ich einen FloatingViewService auf taste klicken. Ich muss es auf meinem Handy laufen lassen, weil ich keine Virtualisierung auf meinem Laptop habe.

Und ja, ich habe fügen Sie die Erlaubnis:

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

Und ich erklärte auch FloatingViewService in der AndroidManifest.xml Datei:

<service android:name=".FloatingViewService" /> 

Aber noch kein Glück. Was mache ich falsch?

Hier ist meine gesamte Code:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:paddingLeft="@dimen/activity_horizontal_margin" 
android:paddingRight="@dimen/activity_horizontal_margin" 
android:paddingTop="@dimen/activity_vertical_margin" 
android:paddingBottom="@dimen/activity_vertical_margin" 
tools:context="com.icetea09.demofloatingview.MainActivity"> 

<Button 
    android:id="@+id/btn_show_floating_view" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_centerInParent="true" 
    android:text="Show Floating View"/>

    return null; 
} 

@Override

    if(!mIsFloatingViewAttached){ 
     mWindowManager.addView(mImgFloatingView, mImgFloatingView.getLayoutParams()); 
    } 
    return super.onStartCommand(intent, flags, startId); 
}

        initialY = params.y; 
        initialTouchX = event.getRawX();

        return true;

        return true; 
      } 
      return false; 
     } 
    }); 
} 

public void removeView() { 
    if (mImgFloatingView != null){ 
     mWindowManager.removeView(mImgFloatingView); 
     mIsFloatingViewAttached = false; 
    } 
} 

@Override 
public void onDestroy() { 
    Toast.makeText(getApplicationContext(), "onDestroy", Toast.LENGTH_SHORT); 
    super.onDestroy(); 
    removeView(); 
} 

}

public class MainActivity extends ActionBarActivity implements View.OnClickListener{ 

private Button mBtnShowView; 
private boolean mIsFloatingViewShow; //Flag variable used to identify if the Floating View is visible or not 

@Override

       mIsFloatingViewShow = false; 
       mBtnShowView.setText(R.string.show_floating_view); 
      } 
      else{

       mBtnShowView.setText(R.string.hide_floating_view);

      break; 
    } 
} 

private void showFloatingView() { 
    startService(new Intent(getApplicationContext(), FloatingViewService.class)); 
} 

private void hideFloatingView() { 
    stopService(new Intent(getApplicationContext(), FloatingViewService.class)); 
} 

}

Verwenden

WindowManager.LayoutParams.TYPE_TOAST 

statt

WindowManager.LayoutParams.TYPE_PHONE
