android.os.NetworkOnMainThreadException in android

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".

Caused by: android.os.NetworkOnMainThreadException
10-30 15:07:35.341: E/AndroidRuntime(732):  at android.os.StrictMode$AndroidBlockGuardPolicy.onNetwork(StrictMode.java:1117)

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.
Enjoy Coding :)

Android Shake animation

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:

package com.mukesh.shakeanimation;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.Toast;

public class MainActivity extends Activity implements View.OnClickListener {

 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);

  View loginButton = findViewById(R.id.login);
  loginButton.setOnClickListener(this);
 }

 public void onClick(View v) {
  Animation shake = AnimationUtils.loadAnimation(this, R.anim.shake);
     findViewById(R.id.pw).startAnimation(shake);
     Toast.makeText(this, "Wrong Password", Toast.LENGTH_SHORT).show();
 }

}

2) activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:background="@drawable/blue_gradient"

    android:orientation="vertical"

    android:padding="10dip" >



    <TextView

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:layout_marginBottom="10dip"

        android:text="Please enter your password:"

        android:textColor="@android:color/white"

        android:textStyle="bold" />



    <EditText

        android:id="@+id/pw"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:clickable="true"

        android:password="true"

        android:singleLine="true" />



    <Button

        android:id="@+id/login"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:background="@drawable/btn_active_pressed"

        android:padding="5dp"

        android:text="Login"

        android:textColor="@android:color/white"

        android:textStyle="bold" />



</LinearLayout>

3. res/anim/shake.xml

<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="500"
    android:fromXDelta="0"
    android:interpolator="@anim/cycle_7"
    android:toXDelta="10" />

4. res/anim/cycle_7.xml

<cycleInterpolator xmlns:android="http://schemas.android.com/apk/res/android"
    android:cycles="7" />

May this will helps someone.
Enjoy coding  :)

Open a new Activity on Receiving the notification in Android

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.

      @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 :)

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 “
             

Step-4. Go to API Access tab from the left menu of web pagee and press Create new
                  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

Photo capture Intent causes NullPointerException on Samsung phones only

Hello Dorid Guys,

Yesterday, I came across  a weird situation . In my application ,I am capturing an image from camera and displaying it inside an imageview. I tested its functionality on many of android device and its working 
fine except "Samsung Galaxy Tab".
In Samsung device the capture intent will be "Null" and I am getting null pointer exception while capturing image from camera in android Samsung S2.

Following code I am using which running fine in all devices except Samsung :

For capturing Image from camera:

Intent captureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

startActivityForResult(captureIntent, CAMERA_CAPTURE);

For choosing an image from gallery:

Intent gallaryIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(gallaryIntent, RESULT_LOAD_IMAGE);


And finally the onActivityResult(int requestCode, int resultCode, Intent data) :

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
       
       if (requestCode == RESULT_LOAD_IMAGE) {
         picUri = data.getData();
         performCrop();
        }

       if (requestCode == CAMERA_CAPTURE) {
  // get the Uri for the captured image
  picUri = data.getData();
  if (picUri != null) {
   performCrop();
  }
 }
 // user is returning from cropping the image
  if (requestCode == PIC_CROP) {
  // get the returned data
  Bundle extras = data.getExtras();
  // get the cropped bitmap
  rectangleBitmap = extras.getParcelable("data");
  // retrieve a reference to the ImageView
  GraphicsUtil graphicsUtil = new GraphicsUtil();
  rectangleBitmap = graphicsUtil.getRoundedCornerBitmap(
  rectangleBitmap, 16);
  ImageView picView = (ImageView) findViewById(R.id.imgView);
  // display the returned cropped image
  picView.setImageBitmap(rectangleBitmap);
  btnMakeMotekon.setBackgroundDrawable(getResources()
                .getDrawable(R.drawable.make));
  btnMakeMotekon.setEnabled(true);
  btnNext.setEnabled(true);
 }
}
}

Now the crop image method, picking the image from gallery or camera and crop it.

private void performCrop() {
 // take care of exceptions
 try {
 // call the standard crop action intent (the user device may not support it)
 Intent cropIntent = new Intent("com.android.camera.action.CROP");
 // indicate image type and Uri
 cropIntent.setDataAndType(picUri, "image/*");
 // set crop properties
 cropIntent.putExtra("crop", "true");
 // indicate aspect of desired crop
 cropIntent.putExtra("aspectX", 1);
 cropIntent.putExtra("aspectY", 1);
 // indicate output X and Y
 cropIntent.putExtra("outputX", 256);
 cropIntent.putExtra("outputY", 256);
 // retrieve data on return
 cropIntent.putExtra("return-data", true);
 // start the activity - we handle returning in onActivityResult
 startActivityForResult(cropIntent, PIC_CROP);
 }catch (ActivityNotFoundException anfe) {
  // display an error message
  String errorMessage = "Whoops - your device doesn't support the 

                   crop action!";
  Toast toast = Toast.makeText(this, errorMessage,

                    Toast.LENGTH_SHORT);
  toast.show();
 }
}

The above code is working fine in most of the devices but when test it on Samsung S2 . I am getting the NullPointerException.
This is very tough time for me because my client wants to release the Application ASAP. And because of this issue he is delaying its time. 

After spending a full day and a night a found the fix for this problem, I added some extra code inside the
onActivityResult method.

The trick is:

if(picUri != null) {
    // do it the normal way
else {
    // do it the "Samsung" way
}

And it works :)

Here is my source code:

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
   super.onActivityResult(requestCode, resultCode, data);  
  if (resultCode == RESULT_OK) {  
  if (requestCode == RESULT_LOAD_IMAGE) {  
    picUri = data.getData();  
    performCrop();  
  }  
  if (requestCode == CAMERA_CAPTURE) {  
  // get the Uri for the captured image  
  picUri = data.getData();  
  /*  
  * In samsung , the picUri will be null and application will  
  * give runtime error In else part we are doing the code for  
  * samsung device  
  */  
  if (picUri != null) {  
    // do it the normal way  
    performCrop();  
  } else {  
   // Describe the columns you'd like to have returned.  
   // Selecting from the Thumbnails location gives you both the  
   // Thumbnail Image ID, as well as the original image ID  
   String[] projection = {  
     MediaStore.Images.Thumbnails._ID, // The columns we wANT  
  MediaStore.Images.Thumbnails.IMAGE_ID,  
  MediaStore.Images.Thumbnails.KIND,  
  MediaStore.Images.Thumbnails.DATA };  
   String selection = MediaStore.Images.Thumbnails.KIND + "=" + // Select  
                // only        // mini's  
     MediaStore.Images.Thumbnails.MINI_KIND;  
      String sort = MediaStore.Images.Thumbnails._ID + " DESC";  
      // At the moment, this is a bit of a hack, as I'm returning  
   // ALL images, and just taking the latest one. There is a  
   // better way to narrow this down I think with a WHERE  
   // clause which is currently the selection variable  
      Cursor myCursor = this.managedQuery(  
   MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,  
   projection, selection, null, sort);  
   long imageId = 0l;  
   long thumbnailImageId = 0l;  
   String thumbnailPath = "";  
   try {  
     myCursor.moveToFirst();  
     imageId = myCursor.getLong(myCursor   .getColumnIndexOrThrow(MediaStore.Images.Thumbnails.IMAGE_ID));  
         thumbnailImageId = myCursor.getLong(myCursor   .getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID));  
     thumbnailPath = myCursor  
  .getString(myCursor    .getColumnIndexOrThrow(MediaStore.Images.Thumbnails.DATA));  
   } finally {  
     myCursor.close();  
  }  
  // Create new Cursor to obtain the file Path for the large  
  // image  
  String[] largeFileProjection = {  
         MediaStore.Images.ImageColumns._ID,  
   MediaStore.Images.ImageColumns.DATA };  
  String largeFileSort = MediaStore.Images.ImageColumns._ID  
     + " DESC";  
  myCursor = this.managedQuery(  
   MediaStore.Images.Media.EXTERNAL_CONTENT_URI,  
   largeFileProjection, null, null, largeFileSort);  
   String largeImagePath = "";  
  try {  
    myCursor.moveToFirst();  
       // This will actually give yo uthe file path location of  
    // the image.  
    largeImagePath = myCursor  
   .getString(myCursor  
  .getColumnIndexOrThrow(MediaStore.Images.ImageColumns.DATA));  
  } finally {  
  myCursor.close();  
  }  
  // These are the two URI's you'll be interested in. They  
  // give you a handle to the actual images  
  Uri uriLargeImage = Uri.withAppendedPath(  
  MediaStore.Images.Media.EXTERNAL_CONTENT_URI,  
  String.valueOf(imageId));  
  Uri uriThumbnailImage = Uri.withAppendedPath(  
  MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,  
   String.valueOf(thumbnailImageId));  
  picUri = uriLargeImage;  
  performCrop();  
  }  
  }  
 }  

Hope this will helps Some one.

Close Popup window on click of backbuttun in android

 Hello Dorid Guys,  
 Yesterday, I stuck in a weird situation , the android popup button will not closed on pressing back  
 button . On android physical back button pressed I am calling popupWindow.dismiss();  
 But it not works for me :( .  
 After spending 1-2 hrs on it , finally I Solved this issue.  
 I am Doing following three steps :  
 1. Initializing the popup window first:  
    View view = LayoutInflater.from(MyDialogActivity.this).inflate(R.layout.poup_icon, null);  
    popupWindow = new PopupWindow(view, LayoutParams.WRAP_CONTENT,    
                 LayoutParams.WRAP_CONTENT, true);  
 2. After initialization call this  
     popupWindow.setBackgroundDrawable(new BitmapDrawable());   
 3. Finally, at the end inside your back button pressed code call this  
     @Override  
      public void onBackPressed() {  
       if(popupWindow != null)  
         popupWindow.dismiss();  
       else  
         super.onBackPressed();  
      }  
 Here is my full source code:  
 package com.popup.activities;  
 import android.app.Activity;  
 import android.content.Context;  
 import android.os.Bundle;  
 import android.widget.ImageView;  
 import android.widget.PopupWindow;  
 public class MyDialogActivity extends Activity {  
  Context mContext = MyDialogActivity.this;  
  PopupWindow popupWindow;  
  ImageView emojiIcon;  
  @Override  
  public void onCreate(Bundle savedInstanceState) {  
   super.onCreate(savedInstanceState);  
       setContentView(R.layout.activity_my_dialog);  
   ImageView emojiIcon = (ImageView) findViewById(R.id.motekon_icon);  
   //onclick of icom  
   emojiIcon.setOnClickListener(new OnClickListener() {  
   @Override  
     public void onClick(View v) {  
  View view = LayoutInflater.from(mContext).inflate(R.layout.popup_        icon, null);  
  popupWindow = new PopupWindow(view, LayoutParams.MATCH_PARENT,  
           LayoutParams.WRAP_CONTENT, true);  
      popupWindow.setBackgroundDrawable(new BitmapDrawable());  
      popupWindow.showAtLocation(view, Gravity.BOTTOM, 0, 0);  
      final GridView gridView = (GridView)view.  
                     findViewById(R.id.gridView1);  
  gridView.setOnItemClickListener(new OnItemClickListener() {  
  public void onItemClick(AdapterView<?> arg0, View v,   
                      int position, long arg3) {  
   popupWindow.dismiss();  
  }  
  });  
      gridView.setAdapter(your adapter);  
  }  
  });  
   }  
   @Override  
   protected void onPause() {  
  super.onPause();  
  if (popupWindow != null)  
  popupWindow.dismiss();  
   }  
  @Override  
  public void onBackPressed() {  
   if (popupWindow != null)  
  popupWindow.dismiss();  
   else  
     super.onBackPressed();  
  }  
 }  
 This is what I am doing in my code and it solve my problem.  
 May this will help some one.  
 Enjoy Coding :)
