Hello Droid Guys,
Yesterday , I found a strange issue, my application is running fine on most of
the android devices. But when I run the same application on Samsung S-3, S2,
Samsung Galaxy Duos it will be crashed and give me the error
"android.os.NetworkOnMainThreadException".
In my application basically I am showing a alert dialog with an logout button and on click of logout
button I am calling the service. This functionality is not working on above few device
and crashes every time on clickinng the logout button .
After spending a lot of time on it I came to know that on device api version below 9 we
can call or write network call in Main UI Thread but above api version 9 it gives error
android.os.NetworkOnMainThreadException. This is happening my case.
There are Two way to fix this Issue:
1.Instead of writing network call in Main UI Thread use Async Task.
2.Add below code into your activity class inside onCreate() method just after the
setContentView(R.layout.activity_main).
if( Build.VERSION.SDK_INT >= 9){
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
Hoping , this will helps you.

Hello Droid Friends,
This is my another android blog in which I am going to explain the Animation
effect(shake Animation ) in android. When you fill wrong input then instead of
showing the toast messege you can also shake the view.
Steps :
1. Create a project with name "Shake animation" and package name
"com.mukesh.shakeanimation".
2. add an "anim" folder inside the res folder.see the image below.
Source Code:
1. Activity Class:
2) activity_main.xml
4. res/anim/cycle_7.xml
May this will helps someone.
Enjoy coding :)

Hello Droid Guys,
In this tutorial , I am going to explain how to open a new activity class
whenever a push notification comes on your device.
Step 1. For this first of all follow Android Goggle Cloud Messaging .
In this blog I already explain how to register your application for GCM,
Obtaining the sender id and getting the registration id from GCM server.
step 2. Once you complete the step-1 then inside your GCMIntentService.java class add
following code.

step 2. Once you complete the step-1 then inside your GCMIntentService.java class add
following code.
@Override
protected void onMessage(Context context, Intent arg1) {
Log.i(TAG, "new message= ");
String message = "success on server";
// displayMessage(context, message);
// notifies user
generateNotification(context, message);
}
Now,
/**
* Issues a notification to inform the user that server has sent a message.
*/
private static void generateNotification(Context context, String message) {
int icon = R.drawable.ic_launcher;
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager)
context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message, when);
String title = context.getString(R.string.app_name);
Intent notificationIntent = new Intent(context, Messenger.class);
notificationIntent.putExtra("MESSAGE",message);
notificationIntent.putExtra("ISNOTIFICATION",true);
// set intent so it does not start a new activity
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent intent =
PendingIntent.getActivity(context, 0, notificationIntent, 0);
notification.setLatestEventInfo(context, title, message, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(0, notification);
}
This , will helps you to open a new class whenever apush notification comes.
On tapping the Notification from notification bar.
Enjoy Coding... :)
Cheers :)

1. Google Cloud Messaging
Sunday, December 23, 2012
Android Goggle Cloud Messaging | GCM | Android push notification
Hello Droid Guys,
This tutorial helps you to implement “Google Cloud Messaging for Android (GCM)" and
sending "Android Push Notification" using GCM.
According to Google, “Google Cloud Messaging for Android (GCM)" is a service which
helps developer in sending data from server to there "Android Application" whenever
there is new data added on server. Also , No need to request server after every time
period(the timely fashion which we mostly did to fetch updated data from server after a
fixed time period for e,g after every 6hrs,or a day).
1. How it works ?
1. Android device sends a "sender id" and "application id" to GCM server for
registration.
2. After Successfully registration on server, the GCM server generate a
"Registration id" and returns it.
3. After receiving this "registration id" the device send this "registration id "
to our server (i.e. my mysql server).
4. Our server store this "registration id" into database for later usage.
Registering Your Application for “Google Cloud Messaging for Android (GCM)":
Step-1. Goto Here and create a new project. (If you haven’t created already
otherwise it will take you to dashboard).
Step-2. Click on create project and check your browser url, It will change some thing
like:
" https://code.google.com/apis/console/#project:4815162342 "
Note: This Id will be used by the Android Device while Registering for Push Notification.
Step-3. Choose Service tab from the left side menu on the web page. and turn on
“ Google Cloud Messaging for Android “
Server key and note down the generated key.
Creating Andrid application for GCM:
Note: Before starting to create android application , first update your ADT plugin to 20.
1. Go to window => android Sdk => extras=> choose Google Cloud Messaging for Android Library.
Now Start Creating Android application project and remember to add gcm .jar inside your project lib folder.
You can easily find this gcm.jar inside your android_sdk/extras/google/gcm after updating your ADT and
SDk.
Now place following file inside your project
1.PushAndroidActivity.java
package com.mukesh.gcm;
import static com.mukesh.gcm.CommonUtilities.SENDER_ID;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;
import com.google.android.gcm.GCMRegistrar;
public class PushAndroidActivity extends Activity {
private String TAG = "** pushAndroidActivity **";
private TextView mDisplay;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
checkNotNull(SENDER_ID, "SENDER_ID");
GCMRegistrar.checkDevice(this);
GCMRegistrar.checkManifest(this);
setContentView(R.layout.main);
mDisplay = (TextView) findViewById(R.id.display);
final String regId = GCMRegistrar.getRegistrationId(this);
Log.i(TAG, "registration id ===== " + regId);
if (regId.equals("")) {
GCMRegistrar.register(this, SENDER_ID);
} else {
Log.v(TAG, "Already registered");
}
mDisplay.setText("ffffff " + regId);
}
private void checkNotNull(Object reference, String name) {
if (reference == null) {
throw new NullPointerException(getString(R.string.error_config,
name));
}
}
@Override
protected void onPause() {
super.onPause();
GCMRegistrar.unregister(this);
}
}
2.GCMIntentService.java
package com.mukesh.gcm;
import static com.mukesh.gcm.CommonUtilities.SENDER_ID;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import com.google.android.gcm.GCMBaseIntentService;
public class GCMIntentService extends GCMBaseIntentService {
public GCMIntentService() {
super(SENDER_ID);
}
private static final String TAG = "===GCMIntentService===";
@Override
protected void onRegistered(Context arg0, String registrationId) {
Log.i(TAG, "Device registered: regId = " + registrationId);
}
@Override
protected void onUnregistered(Context arg0, String arg1) {
Log.i(TAG, "unregistered = " + arg1);
}
@Override
protected void onMessage(Context arg0, Intent arg1) {
Log.i(TAG, "new message= ");
}
@Override
protected void onError(Context arg0, String errorId) {
Log.i(TAG, "Received error: " + errorId);
}
@Override
protected boolean onRecoverableError(Context context, String errorId) {
return super.onRecoverableError(context, errorId);
}
}

package com.mukesh.gcm;
public final class CommonUtilities {
static final String SENDER_ID = "4815162342";
}
