Error and several warnings in my app

Platform & version: Android 2.3.7.

Host Operating System: Windows 7.

My application is working perfectly, but in some console errors and warnings appear.

I would like to know the explanation for these errors and warnings. Can place links to other questions if there is already a solution to some of the errors.

• First code: the app is started on device. The screen in question is to login into the app

  Titanium Command-Line Interface, CLI version 3.2.1, Titanium SDK version 3.2.1.GA

• Second code: the user is already logged. On this screen there is a tableview, and it is also the first error that occurs and unique the application (I think).

• Third code: the application is closed.

  [WARN] :   KeyCharacterMap: Can't open keycharmap file

Look at each line if possible please!
