RecyclerView with multiple View Type | RecyclerView with different view types | View Pager inside RecyclerView

Hello Friends,
              Today I am going to share my another android tutorial, with the help
of this we can easily create a Recyclerview with multiple different types
of view .
Also this tutorial helps you to create a View pager inside RecyclerView,

1. MainActivity.java :

package com.developer.solutions.recyclerviewwithmultipleviewtype.activity;

import android.app.Activity;
import android.content.Intent;
import android.os.Binder;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

    protected void onCreate(Bundle savedInstanceState) {
        //((TextView) findViewById(R.id.tv)).setText("Welcome user");
        mUnbinder = ButterKnife.bind(this);

        ArrayList list = new ArrayList<>();
        list.add(new Data(Data.VIEW_PAGER, "Hello. This is the View Pager view type with images", 0));
        list.add(new Data(Data.IMAGE_TYPE, "A view type with Image and Textview", R.drawable.disneys_cinderella));
        list.add(new Data(Data.AUDIO_TYPE, "Hey, A view type with Button and Textview", 0));
        list.add(new Data(Data.IMAGE_TYPE, "Hi again. A view with Image and Textview", R.drawable.snow));

        MultiViewTypeAdapter adapter = new MultiViewTypeAdapter(list, this);
        final LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);
        mRecyclerView.setItemAnimator(new DefaultItemAnimator());

    protected void onDestroy() {

App crashed on launch | Android Studio App crashed on launch | App crashed on launch- Android 4.4

Hello friends,

Today I found the strange issue while making an signed/released Apk.

My app getting crashed when app launched on Android 4.4, 4.2 and other devices
and Its working fine with Debug build. After spending lots of time I found that the
issue is with Android studio 2.0 or higher.

The reason of crash is in Android studio 2.0 and higher Google added a new feature
of Instant Run which makes your development/emulation faster.The Instant run is
enabled in latest android studio. We need to make it disable while making a signed
release build.

Steps to Disable:
1. Open the Settings or Preferences dialog: On Windows or Linux, select File > Settings
    from the main menu. On Mac OSX, select Android Studio > Preferences from
    the main menu.
2. Navigate to Build, Execution, Deployment > Instant Run.
3  Unchecked the box next to Enable Instant Run to hoot swap code/resource
    changes on display. 

What is Instant Run??
Instant Run: This feature is supposed to dramatically improve your workflow by letting you quickly see changes running on your device or emulator. It lets you see your changes running “in a near instant,” which means you can continuously code and run your app, hopefully accelerating your edit, build, run cycles. When you click on the Instant Run button, it will analyze the changes you have made and determine how it can deploy your new code in the fastest way. Instant Run works with any Android Device or emulator running API 14 (Ice Cream Sandwich) or higher.

Hope this will help someone.
Enjoy Coding.... :)

Unity | Unity Read SMS Plugin | Unity Pluging : Read all incoming sms

Hello Friends,
              I read a lot that people facing problem in register and un-register the incoming
sms broadcast from Unity. Also reading incoming sms in Unity app .


              So, today I am going to share my first blog on Unity. This post helps you
to read all android incoming sms in your unity app.  Also you can easily register
and un-register the broadcast base on need.

In this tutorial I am going provide you a Unity Plugin(i.e:smsreader.jar) which
communicate b/w your unity app and android native callbacks. Below are the
steps to use it in your unity app :

1. Note: The package name which you have to use to access the plugin method is

    Permission:  Add below permission inside your unity app manifest.xml file.
         <uses-permission android:name="android.permission.RECEIVE_SMS"/>
         <uses-permission android:name="android.permission.READ_SMS" />

2.  The plugin contains to static method which will be call from unity app :
          A. registerBroadcastReceiver() :  When your unity app launch we first need to
              call this method for registering the broadcast receiver. Below is code snapshot.
              These two methods and class are there in plugin we just need to add that
               plugin as a jar and call it.
  * This method register the Broadcast receiver
  * @param view
 public static void registerBroadcastReceiver() {
    if (broadCastReceiver == null) {
  broadCastReceiver = new IncomingSms();
  new IntentFilter("android.provider.Telephony.SMS_RECEIVED"));

          B. unregisterBroadcastReceiver() : Whenever you want to stop reading incoming
               sms call this method or when your unity app goes in background.
  * This method un-register the Broadcast receiver
  * @param view
 public static void unregisterBroadcastReceiver() {

  if (broadCastReceiver != null) {
   broadCastReceiver = null;

3. IncomingSms.java:
package com.affle.smsreader;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.telephony.SmsMessage;
import android.util.Log;

import com.unity3d.player.UnityPlayer;

public class IncomingSms extends BroadcastReceiver {

 final SmsManager sms = SmsManager.getDefault();

 public void onReceive(Context context, Intent intent) {

  // Retrieves a map of extended data from the intent.
  final Bundle bundle = intent.getExtras();

  try {

   if (bundle != null) {

    final Object[] pdusObj = (Object[]) bundle.get("pdus");

    for (int i = 0; i < pdusObj.length; i++) {

     SmsMessage currentMessage = SmsMessage
       .createFromPdu((byte[]) pdusObj[i]);
     String phoneNumber = currentMessage

     String message = currentMessage.getDisplayMessageBody();

     if (UnityPlayer.currentActivity != null) {
        "OnMessageReceived", "" + message);
    } // end for loop
   } // bundle is null

  } catch (Exception e) {
   Log.e("SmsReceiver", "Exception smsReceiver" + e);



Download the plugin from here : SmsReader.jar
Hope this will help some one.
Happy Coding ... :)
