Hey Developers
im working on this for several days and I have no clue what the
problem is:
Ok first, what I want to do.
I have an app (the service) that includes a native method, which needs
a lot of time. And I have another app (the activity) which shows the
results of this method. For the communication between them I used IPC,
like it is explained in the book I use (Android 2, it is german...:
( ). I tested it in one project where the service is in a separate
process and it worked. But when I start with two separate applications
I got the following errors in logcat:

the service is called mittwochnachtservice
and the activity mittwochnacht

public class mittwochnacht extends Activity implements OnClickListener

private ServiceConnection mServiceConnection = new ServiceConnection()
{
public void onServiceConnected(ComponentName className,IBinder
binder) {

bindService(new
Intent("test.versuch.fuenf.service.intent.action.GET_NATIVE_STRING"),
mServiceConnection,Context.BIND_AUTO_CREATE);
//GET_NATIVE_STRING is defined in my manifestfile for the service
}
}
and this is my service
public class mittwochnachtservice extends Service{
private static Manager manager= new Manager(); //manages the native
code
private final RemoteCallbackList<IServiceCallback> callbacks = new
RemoteCallbackList<IServiceCallback>();
private final IServiceRemote.Stub mBinder = new IServiceRemote.Stub()
{

{
final String teststring = manager.stringFromJNI();
return teststring;
}
@Override
public void getnativeStringAsynchron() throws RemoteException
{

for(int i = 0; i<countCallbacks;i++){

}
@Override

}
};
@Override
public IBinder onBind(Intent intent) {

}
}
and the two aidl files:
package test.versuch.fuenf.service;
import test.versuch.fuenf.service.IServiceCallback;
interface IServiceRemote{
String getnativeString();
oneway void getnativeStringAsynchron();
void registerCallback(IServiceCallback callback);
void killCallback(IServiceCallback callback);
}
________
package test.versuch.fuenf.service;
interface IServiceCallback{
void nativeString(in String strong);
}
It already crashes without calling one of the methods of the
interface... If I comment the "private ServiceConnection
mServiceConnection = new ServiceConnection(){.." and the "private
final IServiceCallback serviceCallback = new
IServiceCallback.Stub()..." it is showing me my activity. with this
methods it crashes...
Can you help me?
Thanks for you help
