When I try to test my application via SmartPhone this error appears.
12:34:20 Session 'app': Error Installing APK
This message appears in Debug
com.android.ddmlib.AdbCommandRejectedException: device unauthorized. This adb server's $ ADB_VENDOR_KEYS is not set Try 'adb kill-server' if that seems wrong. Otherwise check for a confirmation dialog on your device. Error while Installing APK
Can anyone help me?
