I am trying to build sample Android app in which the main activity contains several fragments, including a YouTubePlayerFragment. I get no errors with my implementation, but when I run the app in an emulator or on my phone, the main activity is completely blank and unresponsive. The app works fine if I remove the fragment containing the YouTube player.
Any help is greatly appreciated.
Here is my code:

YouTubeFragment ytf = newInstance();
ytf.init();
//inside fragment use getFragmentManager instead of getFragmentSupportManager
getFragmentManager().beginTransaction()
.add(R.id.youTubePlayer, ytf)
.commit();
return view;
}

Because the class is somewhat old, and the IDE changed so much, i'm struggling a bit trying to do the same steps of the class.
I have created my Intent and i can send it by clicking on the ListView Item. Then it switches activities from the MainActivity to the DetailActivity. Yet when the DetailActivity is displayed (using DetailActivityFragment) the toolbar disappears. I compared XML's and made some improvements but now the toolbar isn't populated like the previous toolbar. The activity also "fills" the notification bar (the bar that extends to the drawer).
Question is, what am I doing wrong and what can i do to replicate the MainActivity toolbar to the new DetailActivity?

Some ScreenCaptures from debugging on my mobile:
MainActivity
DetailActivity Where the bug happens
I am following the Android Development tutorials on Udacity and I have came across a problem in the app that I can't seem to work out how to fix.
I have created the new activity, and the Intent works perfectly fine in loading the new activity, the only problem is that when the second activity loads there is no actionbar that loads. Any Ideas?

When changing the XML and Java file to include the toolbar, the frame layout and toolbar now overlap each other. See below.

Should add Toolbar into the second activity's layout, and
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
EDIT
activity_detail.xml should be like this:

When I go into the view hierarchy it show RelativeLayout as the Viewgroup for the TextView and AnalogClock. So where did the fragment view go? Isn't the fragment contain the RelativeLayout, TextView, and AnalogClock in fragment_main.xml since it is the one that is inflated in MainActivity.java? Also, where did the TextView with "TestTest" as its text go?

Do below changes to your code:
implement AdapterView.OnItemSelectedListener:
public class MainActivity extends ActionBarActivity implements AdapterView.OnItemSelectedListener {
Change switch cases to 0 and 1. (The count starts with 0)
Comment out the line: if (mp != null && mp.isPlaying())
Change onItemSelected() callback method to:
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
soundSelection = pos;
}
was testing som things in Android Studios and ran in to this error:

The problem is the way you're doing this. For the Activity, you don't set the Fragment's view, you set a separate view that has a spot to put a Fragment. Depending on how you did your PlaceHolderFragment, the following ought to get a working app.
First add this file:
activity_main.xml
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
Then change this stuff in your Activity:
LoginActivity.java
/* Same stuff*/
#Override
protected void onCreate(Bundle savedInstanceState) {
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
//This is the important change right here!
setContentView(R.layout.activity_main);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new PlaceholderFragment())
.commit();
}
//The stuff that you had handling buttons should go in your
//PlaceHolderFragment class's onCreateView() method
}
I hope this helps. Good Luck!
