According to new IDE for android I decided to import projects from my old eclipse.
Unfortunatelly I cannot run them because of information Error: Activity Class not specified This error can be found I user reproduce steps:
Module navigation list
Launch default activity or Launch
No matter what I do, I still get at the bottom of Run/Debug Configurations windows error.
How am I supposed start my android projects?

Obviously, try to clean your project from android studio : “Build -> Clean Project”. This will clear your build folders. Clear the cache of Android Studio using “File -> Invalidate Caches / Restart” choose “Invalidate and restart option” and close Android Studio.
The flags you can use to modify the default behavior are: FLAG_ACTIVITY_NEW_TASK. Start the activity in a new task. If a task is already running for the activity you are now starting, that task is brought to the foreground with its last state restored and the activity receives the new intent in onNewIntent() .
How do I fix launching Studio error? Open Start menu > computer > System Properties > Advanced System Properties. In the Advanced tab > Environment Variables, add a new system variable JAVA_HOME that points to your JDK folder, for example, C:\Program Files\Java\jdk1. 7.0_21.
Please check if your src folders are added into the build path. I imported my workspace from Eclipse by export to Gradle, and by default only gen folders were marked as source files. Because of that, IDE cannot compile your source files and cannot launch any activities.
Hope that will help.
