New to Android etc.
So I was recommended this demo:
http://dj-android.blogspot.in/2013/02/android-google-map-v2-part-1.html
I followed it, but something must have gone wrong.
...
In workspace I have my own project:
Inside this project: In "Libs" I have added "android-support-v4.jar"
Inside this project: In Android Depencides I have "android-support-v4.jar"
Inside this project: In References Libraries I have "google-play-services.jar"
Inside this project: In References Libraries I have "android-support-v4.jar"
...
In workspace I have google-play-services_lib as a project:
Inside this project: In "Libs" I have "google-play-services.jar"
Inside this project: In "Libs" I have "google-play-services.jar.properties"
Inside this project: In "Android Dependencies" I have "google-play-services.jar"
...
When I run above project on SGII v4.1.2 I get black screen followed by crasj followed by error:

NOTE 1:
Do you guys belive it can be a problem related to the API key somehow? I use this as API key:
HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH;com.exampledomain.exampleproject
Notice the ending. Is that correct?
I had to edit the output from keytool, so not 100% sure the API key is good. See:
Maps v2 API Key on Android
NOTE 2:
Some screenshots of my current configuration:
If you believe the cause of my problems is that Google Play Services is not installed correctly, I have created a separate SO for that at: Can not install google-play-services into Eclipse correctly (trying to get maps working)
Try this one:
link
it's a blog post i wrote on creating a Google Map API V2.
UPDATE:
I took a picture from my working map project. ignore the crash reporting services libs like acra, flurry, bugsense and crittercism. other then those you project looks the same?
do you have google-play-services_lib.jar in your Android Dependencies folder?
In References Libraries I have added "google-play-services.jar"
That is incorrect. Please remove that. Then, import the Play Services Android library project to your Eclipse environment, and attach it to your project.
Quoting the documentation:
Copy the /extras/google/google_play_services/libproject/google-play-services_lib library project into the source tree where you maintain your Android app projects.
If you are using Eclipse, import the library project into your workspace. Click File > Import, select Android > Existing Android Code into Workspace, and browse to the copy of the library project to import it.
To set up a project to use the Google Play services SDK... Reference the library project in your Android project. See the Referencing a Library Project for Eclipse or Referencing a Library Project on the Command Line for more information on how to do this.

I recently moved to MoPub and it all appears to be working well except for I have started getting this exception saying that com.millennialmedia.android.VideoPlayer can not be found. I looked and it isn't on the Millennial jar (I just got the latest from their site). Also my AndroidManifest mentions that class and Android Studio also says it can't be found.
This is what I have there:
<activity android:name="com.millennialmedia.android.MMActivity" android:theme="#android:style/Theme.Translucent.NoTitleBar" android:configChanges="keyboardHidden|orientation|keyboard" />
<activity android:name="com.millennialmedia.android.VideoPlayer" android:configChanges="keyboardHidden|orientation|keyboard" />
On Android Studio the VideoPlayer part is red.
This is the exception I got:
java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{mypackage/com.millennialmedia.android.VideoPlayer}: java.lang.ClassNotFoundException: Didn't find class "com.millennialmedia.android.VideoPlayer" on path: /data/app/mypackage-1.apk

Looking at the latest Millennial Media documentation, it looks like
com.millennialmedia.android.VideoPlayer
isn't included. This may be an update that needs to be made.

I am doing a project in a company so I had to hide the urls in the error code above, but urls are working, they are not problem. Any help appreciated, thanks.
I learned that this AsyncHttpClient library is not for Android, so it is not working properly on all versions of Android. There is a library parallel to this library for Android: http://loopj.com/android-async-http/
Android is throwing NoClassDefFoundError for ~1% of my users, no specific SDK version.
It's happening In my activity in the onCreate function when it try's to get an instance to a Singleton class i have in my project.
The singleton class it self doesn't reference any libs jar.
I tried on same devices it's heppening (e.g. SGH-T989) with no success.
Edit: adding the stack trace

I have a problem when I run my app and select an item from my spinner instead of opening a new class like it is supposed to the app crashes, I was wondering if anyone could help me with why this is happening. I am not sure what part of the code to include, so I will include the Logcat and if you request any code I will edit this post.
Thanks.

Normally when app crashes with the click on spinner, the problem lies with the adapter you are using to populate the spinner, check carefully the length of apapter you defined. Follow this code
int num = SpinnerData.length;
SpinnerData = new String[num];
Log.d("ArrayAdapter",""+ SpinnerData.length);
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(CurrentActivity.this, android.R.layout.simple_list_item_1, SpinnerData);
//spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(spinnerArrayAdapter);
check carefully length ..I hope this help
I have a project that uses the GoogleMaps API, and the support library for Fragments. I have a working map in one activity already, so I know that the API and library are all set up right. I am trying to add a map in a fragment as part of a new activity.
The activity extends an android.support.v4.app.FragmentActivity, and the xml file contains:
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="250dp"
android:name="com.google.android.gms.maps.SupportMapFragment" />
But when I run I get the error:

All the information I can find about this error is about not having the google-play-lib properly installed both as a jar and an imported module, but I have that done - and a working map in another activity.
Any ideas?
You have to reference google play services library instead of adding jar and map_attrs.xml (and other files, like strings.xml) to your project.
If you do, you also might have deleted res/values/map_attrs.xml by accident.
