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;
}

I'm having a trouble creating this new activity - Udacity Project Sunshine Lesson 3

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?

ActionBar won't show up on new Activity

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:

Trying to set element state from SharedPreferences, but only the default value is applied

OK so I'm trying to make a settings activity, and that's not going well. Right now it only has one setting which is displayed as a Spinner.
I'm successfully saving the selected item to SharedPreferences, but I can't figure out how to make the activity apply the saved data to the View on start.
I am trying to apply whatever int is paired with the key "spinnerPosition" to Spinner.setSelection();, but the default value in sharedPreferences.getInt(String key, int defValue); overrides it.
Here is the file sharedPreferences saves to:
<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<map>
<string>com.example.SettingsActivity$1#277a0f70</string>
<string name="finalWeighType">Pounds</string>
<int name="spinnerPosition" value="1" />
</map>
And some Logcat:

You're trying to read spinnerPosition value from SharedPreferences instance with name spinnerPosition, while saving spinnerPosition value for SharedPreferences with name WeightType. You should either read the spinnerPosition value from SharedPreferences instance with name WeightType or save it to the SharedPreferences instance with name spinnerPosition.

Android - Activity with YouTubePlayerFragment blank and unresponsive

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.

Text Fields and Spinners in Eclipse

How do i set a text field in Eclipse to work in conjunction with an item selected in a Spinner? EXAMPLE- If the user selects the second item (out of lets say 3 in the drop down menu) i want them to be able to use the text field to the fight of the spinner to set a value to that item selected. Think of it like a translation tool. If the person selects English out of the menu of languages and then types in an english word (in the text field) i want it to be able to CONVERT that to whatever they chose in the second spinner (Spanish) once they hit the "convert" button.
I apologize if this question seems more in need of a java/eclipse lesson then code help, but i appreciate any help at all :)

Well, i cannot tell you about your conversion thingy but i will tell you how to listen to do something based on a selected spinner entry and how to manipulate textfields. The rest you have to code :-)
Here comes a class that implements a spinner, and does something based on the selected option in the spinner. It can be made very different too but this should explain things easy.
public class MyClass extends Fragment implements AdapterView.OnItemSelectedListener {
// Your Spinner
public Spinner spinner;
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
final View view = inflater.inflate(R.layout.tab2, container, false);
// Customize from here
final TextView textview = (TextView) view.findViewById(R.id.textView);
final Button button = (Button) view.findViewById(R.id.btn_calculate);
setSpinnerContent( view );
// attach an OnClickListener
button.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
Integer selectedOption = spinner.getSelectedItemPosition();
if (selectedOption==0) {
myString = "Option 1 selected";
}
if (selectedOption==1) {
myString = "Option 2 selected";
}
if (selectedOption==2) {
myString = "Option 3 selected";
}
textview.setText(myString);
}
}
);
return view;
}
private void setSpinnerContent( View view )
{
spinner = (Spinner) view.findViewById( R.id.spinner );
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(getActivity(), R.array.planets_array, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter( adapter );
}
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) { // ItemsSelected
//An alternate way to listen to the selected items
}
public void onNothingSelected(AdapterView<?> parent) {
// Another interface callback
}
}
The spinner gets content from an String XML resource like this:
<string-array name="planets_array">
<item>Euro</item>
<item>US-Dollar</item>
<item>Yen</item>
</string-array>

spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
String val = spinner.getSelectedItem().toString();//Getting Value of Selected Item
txtPerc.setText(val);//TextView
}
public void onNothingSelected(AdapterView<?> parent) {
// TODO Auto-generated method stub
}
});
Do Something Like This.. And please Clear Your Question.
Hope Its Help..
