From my MainActivity, when I press a button, I have to open another activity that extends AppCompacActivity. The problem is that I get my application to crush because of an unhandled exception. Here is the code
MainProgram code:
Button NextButton = (Button)findViewById(R.id.next_button);
NextButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(getApplicationContext(), GeofenceMainActivity.class);
startActivity(intent);
}
});
GeofenceMainActivity code:
package com.clb.apokalos.todolistas;
import android.app.PendingIntent;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

import java.util.ArrayList;
import java.util.Map;
/**
* Demonstrates how to create and remove geofences using the GeofencingApi. Uses an IntentService
* to monitor geofence transitions and creates notifications whenever a device enters or exits
* a geofence.
*
* This sample requires a device's Location settings to be turned on. It also requires
* the ACCESS_FINE_LOCATION permission, as specified in AndroidManifest.xml.
*
* Note that this Activity implements ResultCallback<Status>, requiring that
* {@code onResult} must be defined. The {@code onResult} runs when the result of calling
* {@link GeofencingApi#addGeofences(GoogleApiClient, GeofencingRequest, PendingIntent)} addGeofences()} or
* {@link com.google.android.gms.location.GeofencingApi#removeGeofences(GoogleApiClient, java.util.List)} removeGeofences()}
* becomes available.

public class GeofenceMainActivity extends AppCompatActivity implements
ConnectionCallbacks, OnConnectionFailedListener, ResultCallback<Status> {

super.onCreate(savedInstanceState);

public void populateGeofenceList() {...}
private void setButtonsEnabledState() {...}
}
This code has been modified since in it's original implementation, it was extending ActionBarActivity (now deprecated), so I modified the code by substituting ActionBarActivity with AppCompatActivity.
The error code is just: threadid=1: thread exiting with uncaught exception (group=0x41da6438)
Could you help me? Try blocks doesn't seem to help me to find a solution.
EDIT: I've got the stacktrace

try adding this theme in your manifest:
android:theme="@style/Theme.AppCompat" >
in activity tag
<activity
android:name=".GeofenceMainActivity"
android:label="@string/app_name"
android:theme="@style/Theme.AppCompat" />
