Question

I am writing a very simple Android app constituted by an activity and a service. I load my service in the activity by doing

@Override
public void onResume()
{
    super.onResume();

    mServiceIntent = new Intent(this, RemoteIntegerService.class);
    ComponentName name = startService(mServiceIntent);
    TextView mainText = (TextView)findViewById(R.id.mainText);
    mainText.setText(name == null ? "(null)" : name.getClassName());
}

When I run the application on my Galaxy Tab or in a virtual device, everything looks fine, and the mainText reads the correct class name.

But when I start the app in Eclipse with adb’s “debug over usb feature”, I have an error in the Intent constructor (in the real device as well as in a virtual one). Here’s the stack trace :

Edit

• Copied the full stack trace

• MyService -> RemoteIntegerService (real name, to be coherent with stack trace)

Edit 2 – Sub-question

I can’t find any information about the error. The program just stops, I see the stack trace, but nothing else. On Visual Studio I have a popup describing the Exception that occured. Is there anything like that in Eclipse ?

Answer 1

As Julien pointed out the debugger may stop with the message:

defineClass(String, ClassLoader, int, ProtectionDomain) line: not available [native method]

because a breakpoint has been set on a class. Removing the breakpoint solve this problem.
