Android Error: Unable to add window — token null is not for an application

Hello Friends,
                 most of us facing the issue of  Unable to add window — token null
while calling alert dialog from our service class.

As, I am using activity class not the fragment so I am using getApplicationContext()
(as from service we face context issue so instead of using "this" am using
application context) for creating "AlertDialog.Builder" but still facing the issue
while calling dialog.show.

android.view.WindowManager$BadTokenException:
  Unable to add window -- token null is not for an application
    at android.view.ViewRoot.setView(ViewRoot.java:509)
    at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:177)
    at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:91)
    at android.app.Dialog.show(Dialog.java:241)

Here is my code:

AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
     getApplicationContext());
//ok and cancel button code
...........
...........
AlertDialog alertDialog = alertDialogBuilder.create();
alertDialog.show();

Then after searching a lot I found the solution, I made following few changes in my
code and Its worked for me.

AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
     getApplicationContext());
//ok and cancel button code
...........
...........
AlertDialog alertDialog = alertDialogBuilder.create();
/*
* Window token null exception, when trying to show alert dialog from
* service class.use alertDialog.getWindow() for getting window and
* add permission in manifest
*/
alertDialog.getWindow().setType(WindowManager.LayoutParams.
    TYPE_SYSTEM_ALERT);
alertDialog.show();

Also need to add following permission in your manifest file

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />

Hope this will helps some one.
Enjoy coding... cheers :)

Android Block App | Android blacklist few application

Hello Friends,
               Today, I am sharing my another tutorial. Actually I want to blacklist
some application from my android application.So, that whenever user try to open
facebook,whatsapp,youtube and any other app, my app prevent them and it
ask user to enter the admin for accessing that app.

I go through many tutorial and android forum and found that they are doing by
making phone as "rooted device" or by installiing some 3rd party application
for eg:AppLock.

But, I don't want any 3rd party app and also don't want to make my device as rooted.
As this app is not for my personal use and making device as rooted is not good idea,
because, its have lots of side effects.

After doing lots of R&D I found an way to achieve this. I used android service which
running in background and monitoring the launcher app.

Here is my code:

1.ServiceDemoActivity.java

package com.android.services;

import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.support.v4.content.LocalBroadcastManager;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;

public class ServiceDemoActivity extends Activity {

 TextView notification;
 Button stop;
 Context ctx = ServiceDemoActivity.this;

 /** Called when the activity is first created. */
 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);
  notification = (TextView) findViewById(R.id.notification);
  if (Helper.CheckIfServiceIsRunning(ctx)) {
   notification.setText("Continuation of last started service");
  } else {
   notification.setText("Service started now only");
   startService(new Intent(this, MyService.class));
  }

  stop = (Button) findViewById(R.id.stop);

  stop.setOnClickListener(new View.OnClickListener() {

   @Override
   public void onClick(View v) {
    if (Helper.CheckIfServiceIsRunning(ctx)) {
     ctx.stopService(new Intent(ctx, MyService.class));
     notification
       .setText("Service stopped - to start the          service go out and come inside the application");
        LocalBroadcastManager.getInstance(ctx).unregisterReceiver(
       broadcastReceiver);
    }
   }
  });
 }

private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
 @Override
 public void onReceive(Context context, Intent intent) {
  // blockApp();
  System.out.print("-------testing----------");
  Toast.makeText(getApplicationContext(), "Installing any app",
     Toast.LENGTH_LONG).show();
  }
 };

 @Override
 public void onResume() {
  super.onResume();
  LocalBroadcastManager.getInstance(this)
    .registerReceiver(broadcastReceiver,
      new IntentFilter(MyService.BROADCAST_ACTION));
 }

 @Override
 public void onPause() {
  super.onPause();
  // unregisterReceiver(broadcastReceiver);

}

  toast.show();

}
public static BroadcastReceiver locationBroadcastReceiver = new BroadcastReceiver() {
 @Override
 public void onReceive(Context context, Intent intent) {
  Log.d("======Service is called", "true");
 }
};

public static boolean CheckIfServiceIsRunning(Context ctx) {
 // If the service is running in background

        d) Also Install the "Intel Atom x86 System Image" which is 
             available in under Android 2.3.3 and Android 3.2.
 

2. Creating the  "Google TV Emulator " for running and testing the app:
      1, Open AVD manager
      2.  Select "Device Definitions" tab from top
      3.  Create an "New Device"

     Note : 
            -For 1080p use a resolution of 1920×1080 and a density of xhdpi.
            -For 720p use a resolution of 1080×720 with a density of tvdpi.       

   

        4. Now Create Google TV Emulator :
           

           Note: You may also face the following issue while creating the Google TV AVD

1. go Help | Install New Sofware
2. select "Android Developer Tools Update Site - http://dl-ssl.google.com/android/eclipse/"
3. press "Select All"
4. press "Finish"

Note : While doing above steps I faced other issue i.e:
    You may have an "No repository found error" while installing the tools.

Then I do following tweak I removed the http://dl-ssl.google.com/android/eclipse/ site and then re-added it, then everything downloaded fine.

Hope, this will helps some one.

Android Robotium Test -run robotium tests in a specific order

Hello Friends,
                         This is very common scenario when you are running any testsuits. It
by default runs in alphabetical order. I too faces the same problem while writing the
test case using Robotium.

In my case I want to execute the testcase in following order :
MainLoginScreenTest -> EmailSignUpScreenTest -> EmailLoginScreenTest

But it actually runs in alphabetical order like,
 EmailLoginScreenTest -> EmailSignUpScreenTest - > MainLoginScreenTest

Then I follow this link and find the way to come out from this problem. Here is
my code.

1. AllTests.java

package com.android.test;
import junit.framework.TestSuite;
import android.app.Activity;
import android.test.ActivityInstrumentationTestCase2;

public class AllTests extends 
        ActivityInstrumentationTestCase2<Activity>{
 
 public AllTests(Class activityClass) {
  super(activityClass);
 }

 public static TestSuite suite() {
  TestSuite t = new TestSuite();
  t.addTestSuite(MainLoginScreenTest.class);
  t.addTestSuite(EmailSignUpScreenTest.class);
  t.addTestSuite(EmailLoginScreenTest.class);
  
  return t; 
 }
 
 @Override
 public void setUp() throws Exception {
  
 }
 
 
 @Override
 public void tearDown() throws Exception {
 }

}

2.MainLoginScreenTest.java

package com.android.test;

import android.app.Activity;
import android.test.ActivityInstrumentationTestCase2;
import android.widget.ImageButton;

import com.android.Login.EmailSignUpScreen;
import com.android.Login.MainLoginScreen;
import com.android.android.R;
import com.robotium.solo.Solo;

public class MainLoginScreenTest extends
          ActivityInstrumentationTestCase2<MainLoginScreen> {
 
 private Solo solo;
 private Activity activity;
 
 public MainLoginScreenTest() {
  super(MainLoginScreen.class);
  // TODO Auto-generated constructor stub
 }
 
 @Override
 public void setUp() throws Exception {
  //setUp() is run before a test case is started. 
  //This is where the solo object is created.
  this.activity = this.getActivity();
  this.solo = new Solo(getInstrumentation(), this.activity);
 }
 
 
 @Override
 public void tearDown() throws Exception {
       solo.finishOpenedActivities();
 }

 public void testDisplay() throws Exception {
   solo.waitForActivity(MainLoginScreen.class);
   ImageButton emailLogin = (ImageButton) this.solo.getView(R.id.btn_email_login);
   assertEquals(emailLogin.getId(), R.id.btn_email_login);
   this.solo.clickOnImageButton(1);
   this.solo.waitForActivity(EmailSignUpScreen.class, 1000);
   assertEquals(EmailSignUpScreen.class, solo.getCurrentActivity().getClass());
   //this.solo.goBack();
 }

java.lang.RuntimeException: Stub! in Robolectric

Hello Droid Friends,
                              Have you facing following error while running a test case using
Roboelectric and Junit-4.

Most of stub!  exceptions are because the tests are not annotated with the correct TestRunner. For example in my case I forgot to add:
@RunWith(RobolectricTestRunner.class)

After adding the above annotation the above issue will be fixed.

import static org.junit.Assert.assertNotNull;
import static org.robolectric.Robolectric.shadowOf;

import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.robolectric.Robolectric;
import org.robolectric.RobolectricTestRunner;
import org.robolectric.annotation.Config;
import org.robolectric.shadows.ShadowActivity;

import android.content.Context;

import com.android.Places.MyPlaces;

@RunWith(RobolectricTestRunner.class)
public class MyPlacesTest {
 
 private MyPlaces activity;
 Context ctx;
 ShadowActivity shadowActivity;
 
 @Before
 public void setUp() throws Exception {
  activity = Robolectric.buildActivity(MyPlaces.class)
                .create()
                .get();
  shadowActivity = shadowOf(activity);
  ctx = activity;
 }
 
 /**
   * @testdox: for activity instance test 
   * given: 
   * when:  app launch
   * then: checking the instance of activity
   */
  @Test
  @Config(reportSdk = 10)
  public void testActivityInstance() {
   assertNotNull(shadowActivity.getApplicationContext());
   Assert.assertEquals("Result",activity.getApplicationContext(),sh                       adowActivity.getApplicationContext());
  }

Hope this will help you during writing the test case for your android project.
