Answer 1

So after a lot of searching i came to know that this problem was due to the multidexing. On some phones multidexing don't work. May be due to their Android Version. However i fixed this by introductng an application class

public class MyApplication extends Application {

    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(this);
    }
}

and in menifest i entered the name in application tag like:

<application
        android:name=".MyApplication"
        android:allowBackup="true"
        android:icon="@mipmap/xxxxxx"
        android:label="@string/app_name"
        android:manageSpaceActivity="xxxxxxxxxx"
        android:theme="@style/AppTheme" >

+) Building Apps with Over 65K Method will cause this Error.

+) When your application and the libraries it references reach a certain size ( DEX file of your application can have total number of methods upto 65,536 including Android framework methods, library methods, and methods in your own code), you encounter build errors that indicate your app has reached a limit of the Android app build architecture.

+) To resolve it, include Multidex Configuration in your build.gradle like the highlighted one in picture, along with this override the attachBaseContext(Context base) method in your Application class with the below content.

public class YourParentApplication extends Application {

@Override
protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    MultiDex.install(this);
 }
}

Add this in you Androidmanifest.xml:

<application
    android:name=".YourParentApplication"
    android:allowBackup="true"
    android:icon="@drawable/radiius_logo"
    android:label="@string/app_name"
    android:largeHeap="true"
    android:theme="@style/MyMaterialTheme">

How to enable multidexing with the new Android Multidex support library

Answer 3

It is due to multidexing, your application uses more than 64k methods update your

build.gradle(app level) with

defaultConfig{

.....

multiDexEnabled true

}

dependencies{

.....

compile 'com.android.support:multidex:1.0.1'

}

and

@Override

protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    MultiDex.install(this);
}

in your Application Class
