Android Actionbar Missing After Extending Appcompatactivity

I've recently updated my app extending Appcompatactivity in my Activities. Since then, the Actionbar is gone when I launch an external library Intent. For example, I'm using the H

Solution 1:

First, check your theme it may be like below ("NoActionBar"). Then the action bar is not appearing. If this is your issue. please add an appropriate theme for your application

<applicationandroid:theme="@style/Theme.AppCompat.Light.NoActionBar"
    />

if your theme is not a problem, you can add below content to your XML file. (add this as a first child of your XML file)

<android.support.v7.widget.Toolbar
   android:id="@+id/my_toolbar"
   android:layout_width="match_parent"
   android:layout_height="?attr/actionBarSize"
   android:background="?attr/colorPrimary"
   android:elevation="4dp"
   android:theme="@style/ThemeOverlay.AppCompat.ActionBar"
   app:popupTheme="@style/ThemeOverlay.AppCompat.Light"/>

and add below content to your activity on create method

protectedvoidonCreate(Bundle savedInstanceState) {
    .......
    ToolbarmyToolbar= (Toolbar) findViewById(R.id.my_toolbar);
    setSupportActionBar(myToolbar);
}

Solution 2:

The reason is probably that FeedbackManager.showFeedbackActivity(this, Uri.fromFile(file)) opens a new FeedbackActivity.class which is subclass of Activity.class instead of AppCompatActivity.class, so it can not show the ActionBar.Here is a link https://stackoverflow.com/questions/30681918/nullpointerexception-with-actionbar-setdisplayhomeasupenabledboolean-on-a-nu that explains some reasons.
