Android ActionBar missing after extending Appcompatactivity

Question

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 HockeyApp SDK to launch their FeedbackActivity

Here is my code:

FeedbackManager.showFeedbackActivity(this, Uri.fromFile(file));

And here a screenshot (you can see the ActionBar is gone).

It used to work before until I started extending Appcompatactivity.

For the rest of Activities it works. The ActionBar is gone only when I launch an external library Intent.

Any ideas?

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

 <application
    android: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

protected void onCreate(Bundle savedInstanceState) {
    .......
    Toolbar myToolbar = (Toolbar) findViewById(R.id.my_toolbar);
    setSupportActionBar(myToolbar);
}

@Ale what is the error now? same or different. Please make sure that u add Toolbar as a first child of xml — PushpikaWan, Nov 05 '18 at 15:30
your solution is correct but it doesn't work in out context because we are launching an external Intent. When we launch `FeedbackManager.showFeedbackActivity(this, Uri.fromFile(file));` it opens a new `Activity` (from the HockeyApp SDK) but we cannot modify its layout. — Ale, Nov 07 '18 at 09:12

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.
