I'm currently using Android Studio to develop my own project for Android (my custom launcher)! The thing is, since last update (to version 0.4.0) I can't run my app.
Instead I get the following error:
FATAL EXCEPTION: main

I've searched everywhere I could remember for a solution (or something related) and tried a bunch of stuff already without any success.
- check the "compiler.xml" (there are no excludes)
- clean/build (error persists)
- check the "AndroidManifest.xml" (everything seems correct)
- recreated the whole project (only imported the code and the resources but the error persists)
One thing I did notice in this line
Caused by: java.lang.ClassNotFoundException: Didn't find class "com.natercio.myhome.Launcher" on path: DexPathList[[zip file "/data/app/com.natercio.myhome-2.apk"],nativeLibraryDirectories=[/data/app-lib/com.natercio.myhome-2, /system/lib]]
is that there is an "-2" (and sometimes a "-1") appended to the name of the app (both in the apk file and in the lib path) but I never really noticed this before so I can't tell for sure if this is somehow related with my problem.
Please also take in consideration that I use git and I've already tried to revert any changes to one of my previously stable commits.
UPDATE:
Has anyone else encountered this problem in Android Studio? Is there any other solution to this kind of error that I missed or is this likely to be some bug in the latest android plugin (for android studio).
UPDATE (build.gradle & manifest file):

}
