How to change HomeAsUp indicator in new AppCompat Toolbar?

Question

I wanna change default ActionBar homeAsUp indicator (drawable) in my AppCompat Toolbar. How to achieve that? Only default arrow shows up.

styles (same for other API\

Answer 1

Unfortunately, if this style line is used in a commonly shared AppCompat ToolBar/App bar with other activities in the App, including the main activity, the "navigationIcon" specified will be automatically shown, unlike the standard default HomeAsUpIndicator, which is not shown unless explicitly enabled as desired in an Activity, typically as follows: (in the onCreate())

getSupportActionBar().setDisplayHomeAsUpEnabled(true);

With the above style line, since it behaves in an opposite manner, in a similar fashion, the indicator needs to be explicitly disabled if it is not desired to be shown, as on the main activity, as follows: (in the onCreate())

getSupportActionBar().setDisplayHomeAsUpEnabled(false);

(as observed on Android 4.0.4, 4.3, and 4.4.2 phones)
