    and the app won't run. what thus it mean?

    You are using which version of the AppCompat library?
    V3.52 is up to date (i think)

    So; use v3.51 from the #1 of this thread.

    After Update to 3.52

    AppCompat 3.52 + MSMaterialDrawer 0.93 combination i cannot solve.

    there is a large space between Menu icon and Logo Drawable, or Menu icon and Tittle Subtittle without Logo Drawable that cause tittle and subtitle need to be more shortened.

    how to short this space?? .. thanks

    Are you receiving the following error message in your apps using AppCompat and B4A 7.80+

    Error below copied from another users post.
    Compiling generated Java code. Error
    17: error: cannot find symbol
    public class main extends android.support.v7.app.ActionBarActivity implements B4AActivity{
    Well if you are you should swap the original line below
    #Extends: android.support.v7.app.ActionBarActivity
    With this line
    #Extends: android.support.v7.app.AppCompatActivity
    @corwin42 very first post quotes the following line.
