cannot run my android app on actual device or AVD

Question

Iam doing some android development using android studio 2.0, recently Iam failing in running any app neither in my actual device nor on my AVD. I have make the last updates required for android studio and SDK.

Here are some of the error messages:

Error:Exception in thread "main" 
Error:  at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:482)
Error:  at java.lang.ClassLoader.loadClass(ClassLoader.java:358)
Error:  at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308)

Answer 1

I solved this issue by checking the Use in-process build in the compiler settings.

Ctrl + Alt + s → Build, Execution, Deployment → Compiler
