Answer 1

The error says

android.view.InflateException: Binary XML file line #7: Error
inflating class com.digitalaria.gama.tile.Tile

which means that you have an error on line 7 in your xml file where you’re declaring
com.digitalaria.gama.tile.Tile so check if that class is available.

In your class where you are using the xml file put :

 import com.digitalaria.gama.tile.Tile;

EDIT :

To add Gama library remove it from javaBuildpath and do this instead:

 1. Create a new folder, libs, in your Eclipse/Android project.
 2. Right-click libs and choose Import -> General -> File System, then
    Next, Browse in the filesystem to find the library's parent
    directory and add your GAMA jar.
 3. Right-click on your project, choose Build Path -> Configure Build
    Path, then click the Libraries tab, then Add JARs..., navigate to
    your new JAR in the libs directory and add it.
 4. Clean the project
