du bist immer richtig dude ... @ Samir – sagar
Aber woher kennst du den Fehler von einem so langen Programm. Überprüfen Sie die Protokollkatze auf den Fehler? wenn ja, aus welcher Zeile im Logcat hast du meinen Fehler kennengelernt ??? – sagar
von Ausnahme 'Resources $ NotFoundException: String Ressource ID # 0x1 ' und ich sehe Ihren Code ... so verstehe ich es ... –
