Debug a service

The the debugger will not be able to connect to a service because there is no Main activity. Processes are started by the Android system at some point. To connect the code to the debugger add some code to your project that is executed at an early stage:

//TODO: wjv: remember to remove this for the final code
Toast toastwjv =  Toast.makeText(getApplicationContext(), "waitForDebugger", Toast.LENGTH_LONG);
toastwjv.show();
android.os.Debug.waitForDebugger();

• modify AndroidManifest.xml
• modify project.properties
• Project - clean
