You are using the wrong version of B4AShared.jar (a core library). Reinstall B4A in a new folder.

I reinstall b4a in other location but again get error

 

[Erel]

Which version of B4A are you installing?

 

[omidaghakhani1368]

3.8 4.0 4.3

Only install the latest version. Make sure that the internal libraries folder is empty before you start.
