Answer

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:

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