    This is the wrong place to post it. However you should use a newer version of android.jar (Tools - Configure Paths).

    You should create a new thread in the questions sub forum, and also post a bit more info, specially as it seems to be B4A related too... If possible, the problematic sub should also be posted so that we can try to help you better
