I know there's lot's of these questions, and "solution" is make sure that Android Private Libraries are checked. In my case they are, any other hints? App crash at very beginning.
Here goes stack trace

Solved. From some odd reason ADT preconfigured by google attached same file in /libs directory of project. When you add facebook SDK to class path it attaches it as well. Problem is they have diffrent versions (and sha-1 hash) so eclipse had problem what to do. I just remove /libs directory and it worked. Runs app from facebook tutorial successfully.

The output in Logcat should be read from top(in your case, FATAL EXCEPTION: main onwards). However, you need to find how your activity contributes to the error. In most cases(and definitely not all), you will find Logcat informing you about a line of code inside the scope of your app. This is where the exception originated:
08-02 20:48:37.443: E/AndroidRuntime(3575): Caused by: android.database.CursorIndexOutOfBoundsException: Index 0 requested, with a size of 0
08-02 20:48:37.443: E/AndroidRuntime(3575): at android.database.AbstractCursor.checkPosition(AbstractCursor.java:424)
08-02 20:48:37.443: E/AndroidRuntime(3575): at android.database.AbstractWindowedCursor.checkPosition(AbstractWindowedCursor.java:136)
08-02 20:48:37.443: E/AndroidRuntime(3575): at android.database.AbstractWindowedCursor.getString(AbstractWindowedCursor.java:50)
-------->>>>>>>>> 08-02 20:48:37.443: E/AndroidRuntime(3575): at com.example.note.NoteEdit.populateFields(NoteEdit.java:231)
After this, the error propagates towards the top before reaching:
08-02 20:48:37.443: E/AndroidRuntime(3575): FATAL EXCEPTION: main
08-02 20:48:37.443: E/AndroidRuntime(3575): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.note/com.example.note.NoteEdit}: android.database.CursorIndexOutOfBoundsException: Index 0 requested, with a size of 0
Another thing to be careful about: exceptions don't always occur independently. You can have several exceptions stacked up. In this case, find the exception that is thrown first(lowest in the Logcat output) and work your way to the top.
I am implementing the system andEngine multiplayer for first, then be able to adjust all imports and libraries and runs without any error in MOTODEV, but the emulator "has stopped unexpectedly".
You can see code here.
Error on emulator:

Pay attention to this line from your log:
Unable to instantiate activity ComponentInfo{com.multiplayerand/com.multiplayerand.MainActivity}: java.lang.ClassNotFoundException: com.multiplayerand.MainActivity in loader dalvik.system.PathClassLoader
That line says,you tried to instantiate activity that it's name is MainActivity and it would be in com.multiplayerand pakage,but system could not find any Activity with this Component-info,and so java.lang.ClassNotFoundException has been occurred.
I guess you can solve problem if you:
Check that your Activity name be MainActivity.
Check that MainActivity be in package with name com.multiplayerand.
Check that you registered MainActivity in manifest of your project.

You should check whatever object you are using is not null and re-create it if it is.
