Please anybody have already faced this problem? Please help me find out the solution. Thanks in advance.

Answer 1

In your stacktrace log you can se - it means that system is not able to find following method:

As mentioned in documentation: http://developer.android.com/reference/android/app/ActionBar.html#setHomeAsUpIndicator(android.graphics.drawable.Drawable)

Don't know exactly which one you are trying to use, but both:

setHomeAsUpIndicator(Drawable)

and

setHomeAsUpIndicator(int)

were added in . This means that they wont be available on lower API versions. This is probably the reason for your issue - you are trying to execute this code on phone with lower API version (below JELLY_BEAN_MR2).

You have 2 options:

. Check the API version before calling this method:

if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.JELLY_BEAN_MR2) {
    actionBar.setHomeAsUpIndicator(int);
}

This will avoid crash, but won't take any effect on lower API versions - so you probably want to go with the second option to achieve your styling goals.

. Instead of trying to set homeAsUpIndicator from code - you can do it safely from styles (because it is ) by adding "android:homeAsUpIndicator" attribute. http://developer.android.com/reference/android/R.attr.html#homeAsUpIndicator

<style name="AppTheme" parent="@android:style/Theme.Holo.Light">
    <item name="android:homeAsUpIndicator">@drawable/my_home_as_up_indocator</item>
</style>
