I have an xml file where I am displaying the text from the first tag, treasure name, in a spinner for the user to select. Once selected, I need to be able to access the other data associated to the treasure name selected that is stored in the xml document (in data file stored on device). I've parsed through the xml file and store each item in a separate array list. When a user clicks on a button (Get Clue), I need to be able to display the first clue associated to that treasure. This project is due today by midnight, and this is the last piece I just can't seem to get. Any help would be greatly appreciated. I added code to try and do this:

I ran into same Error (java.lang.ArrayIndexOutOfBoundsException: length=12; index=-1) with spinners too. In my case, I was trying to setAdapter on spinner outside the ui thread. After wrapping the related code inside runOnUiThread, the issue is solved.

the problem is in your sdcard path, use this code to get path of sdcard
String DIR_SDCARD = Environment.getExternalStorageDirectory().getAbsolutePath();
and there is no need to add "/sdcard/" to it, also change your GetFiles method, and remove mkdirs() because sdcard exists before.
look at this example
File sdcard_files_and_folders[] = new File(DIR_SDCARD).listFiles();
for (File fileOrFolder: sdcard_files_and_folders) {
// do any thing that you want, add them to list or...
Log.i("FILE", fileOrFolder.toString());
}

It is my 1st try and I already stucked. Logcat is throwing tons of exceptions and to be honest I can't understand what I'm doing wrong.

I'm sure that I miss something inside of the xml layout file, but I'm not able to spot it as a total beginner.
Ps. here the layout is:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".AllJokes" >
<ListView
android:id="#+id/allJokesList"
android:layout_height="wrap_content"
android:layout_width="match_parent">
</ListView>
</RelativeLayout>
Should I declare something in it? Please, give me a clue!
Caused by: java.lang.UnsupportedOperationException: addView(View) is not supported in AdapterView
you cant add a view to adapterview
your issue is with
ListView layout = (ListView) findViewById(R.id.allJokesList);
layout.addView(adView);
You need to add the adView inside the adapter
http://googleadsdeveloper.blogspot.co.il/2012/03/embedding-admob-ads-within-listview-on.html
Don't try to add an AdView as an element in a ListView. It is a recipe for pain as it will be entirely different to your other items with different needs.
Add it as it's own element either above or below your ListView.
Instead create a LinearLayout either above or below your ListView
<LinearLayout android:id="#+id/adViewContainer
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
and then change this part of your onCreate to
// Add the AdView to the view hierarchy. The view will have no size
// until the ad is loaded.
final ViewGroup adViewContainer = (ViewGroup) findViewById(R.id.adViewContainer);
adViewContainer.addView(adView);
I have problem whit getting my project to work i will
paste the java files and error log hopefully someone can give me a hint.
The app crash when button R.id.bskickaTidSc3 in TidSc3.java is clicked.

In your 2nd Class {{ spinnerListen }} your have declared a flied called spinner2 which is never intiated, but your tying to set an adapter to it.
