Hi,
I know there are many posts around the issue I am facing but I havent
been able to see any yet which addresses my issue.
This is what I am doing:
1. Create 2 apks. (1 with an activity - lets call it F1App and 2nd
with a service - F1Service)
2. Both APKs have same sharedUserId and same android.process and are
signed with the same key - I have been able to confirm that the 2 are
now running in the same process.
3. From App 1 I bind to F1Service
4. Bind returns successfully but I am unable to access the classes
using the binder. The same code works fine in the sample code but the
2 there are in the same apk.
Here is the F1App code.
package f1.f1;
import com.fusionone.F1Service;
import android.app.Activity;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.Bundle;
import android.os.IBinder;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
public class F1App extends Activity {
private boolean mIsBound;
public F1Service mBoundService;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layout);
// Watch for button clicks.
Button button = (Button)findViewById(R.id.bind);
button.setOnClickListener(mBindListener);
button = (Button)findViewById(R.id.unbind);
button.setOnClickListener(mUnbindListener);
}
private ServiceConnection mConnection = new ServiceConnection() {
public void onServiceConnected(ComponentName className,
IBinder service) {
// This is called when the connection with the service has
been
// established, giving us the service object we can use to
// interact with the service. Because we have bound to a
explicit
// service that we know is running in our own process, we
can
// cast its IBinder to a concrete class and directly
access it.
Log.d("Got Binder", "Got Binder" + service);
mBoundService =
((F1Service.LocalBinder)service).getService();
}
public void onServiceDisconnected(ComponentName className) {
// This is called when the connection with the service has
been
// unexpectedly disconnected -- that is, its process
crashed.
// Because it is running in our same process, we should
never
// see this happen.
mBoundService = null;
Toast.makeText(F1App.this,
R.string.local_service_disconnected,Toast.LENGTH_SHORT).show();
}
};
private OnClickListener mBindListener = new OnClickListener() {
public void onClick(View v) {
// Establish a connection with the service. We use an
explicit
// class name because we want a specific service
implementation that
// we know will be running in our own process (and thus
won't be
// supporting component replacement by other
applications).
Intent toSend = new Intent("com.fusionone.F1Service");
bindService(toSend, mConnection, Context.BIND_AUTO_CREATE);
mIsBound = true;
}
};
private OnClickListener mUnbindListener = new OnClickListener() {
public void onClick(View v) {
if (mIsBound) {
// Detach our existing connection.
unbindService(mConnection);
mIsBound = false;
}
}
};
}
Now the F1Service looks like this:
public class F1Service extends Service {
private NotificationManager mNM;
/**
* Class for clients to access. Because we know this service
always
* runs in the same process as its clients, we don't need to deal
with
* IPC.
*/
public static class LocalBinder extends Binder {
public static F1Service myServiceObj;
LocalBinder(F1Service x){
myServiceObj = x;
}
public F1Service getService() {
return myServiceObj;
}
}
@Override
public void onCreate() {
mNM =
(NotificationManager)getSystemService(NOTIFICATION_SERVICE);
// Display a notification about us starting. We put an icon
in the status bar.
showNotification();
}
@Override
public void onDestroy() {
// Cancel the persistent notification.
// mNM.cancel(R.string.local_service_started);
// Tell the user we stopped.
//Toast.makeText(this, R.string.local_service_stopped,
Toast.LENGTH_SHORT).show();
}
@Override
public IBinder onBind(Intent intent) {
return mBinder;
}
// This is the object that receives interactions from clients.
See
// RemoteService for a more complete example.
private final IBinder mBinder = new LocalBinder(this);
/**
* Show a notification while this service is running.
*/
private void showNotification() {
}
}
The error I get is during install time:

I would really appreciate all help on this!
Thanks!
