I am facing this problem for the last two weeks. Can you help me why this problem occurs?
Error occur at this line allClient.callPhoneNumber("+16315192247");

App enters infinite loop trying to connect to HC-06, but no loop is present

My application enters an infinite loop when I press the Connect button to connect to an HC-06 Bluetooth module (Arduino shield). However, there are no loops anywhere in the code when the button is pressed.

For some reason, this problem just suddenly appeared when I tried to employ a loop to keep trying to connect while the connection is not established. I removed that code, but could it still be there somewhere?

Have you overridden the fragment's onActivityResult method?
If not, try overriding it and calling connectService() inside of it, by adding this to your fragment:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
connectService()
}

Android Error with Websocket

Im working on Websocket android application. I want to create Register and Login application with websocket. I am able to connect to websocket server with websocket android project. I have created Register,Login activity with online reference.In register Activity, when I'm storing Registered data to Server using "send" method of websocketclient Java Class I'm getting "java.lang.NullPointerException: Attempt to invoke virtual method 'void org.java_websocket.client.WebSocketClient.send(java.lang.String)' on a null object reference" Error on my Log-cat window.

Do I have to use again below code in Registered activity?
private void connectWebSocket() {

public void onOpen(ServerHandshake serverHandshake) {
Log.i("Websocket", "Opened");
}
#Override
public void onMessage(String s) {
final String message = s;
runOnUiThread(new Runnable() {
#Override
public void run() {
}
});
}
#Override
public void onClose(int i, String s, boolean b) {
Log.i("Websocket", "Closed " + s);
}
#Override
public void onError(Exception e) {
Log.i("Websocket", "Error " + e.getMessage());
}
};
nWebsocketClient.connect();
}

The problem is that your nwebsocket is never initialized, its value is null and that's why you get this error when trying to execute the send method.
You need to initialize it somewhere:
nwebsocket = new WebSocketClient(...);
NB: If you want to share the same instance of WebSocketClient between MainActivity and Register activity, you could make it public static in MainActivity
public static WebSocketClient mWebSocketClient;
Then remove your WebSocketClient nwebsocket from Register and use MainActivity.mWebSocketClient instead.

I think problem might be here. You have just declared your variable
private SimpleFacebook mSimpleFacebook;
you haven't initialized that variable so you got NPE
So initialized it on onCreateView() method.
mSimpleFacebook = SimpleFacebook.getInstance(getActivity());
And yet you get error then you need to finally change
mSimpleFacebook = SimpleFacebook.getInstance();
Add this line to manifest file..
<activity android:name="com.facebook.LoginActivity" android:screenOrientation="portrait" android:configChanges="keyboardHidden|orientation">
</activity>
which would be finally works for you.!!

Calling activitygroup from customlistadapter

Please suggest me how to call activtygroup from listadapter.

Make it like this you can access everything by doing like this.
public class AddRemoveFriendScreen extends ActivityGroup implements OnClickListener, IServerResponse
{
#Override
protected void onCreate(Bundle savedInstanceState)
{
.......
}
class AllyListAdapter extends BaseAdapter
{
//Now you can call everything from ActivityGroup
}
}
Hope this will help you.

According to the android developper reference, you may use Fragments.
ActivityGroup is deprecated. Use the new Fragment and FragmentManager APIs instead; these are also available on older platforms through the Android compatibility package.
You can try this trick.
inviteBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if(ctx instanceof ActivityGroup){
Intent intent = new Intent(ctx.getParent(),AddRemoveFriendScreen.class);
//intent.putExtra("friendId", allyBean.getUserId());
ctx.getParent().startActivity(intent);
}
else{
Intent intent = new Intent(ctx,AddRemoveFriendScreen.class);
//intent.putExtra("friendId", allyBean.getUserId());
ctx.startActivity(intent);
}
}
});
If it doesn't work just use internal class for your adapter in your AddRemoveFriendScreen class.
