android.os.ServiceSpecificException: GPIO2_IO02 is already in use (code 16)
问题 I am working on android things(Pico i.MX7D I/O).I got android.os.ServiceSpecificException: GPIO2_IO02 is already in use (code 16) exception,What it means by this? Please help me. My sample program is cloned from https://github.com/androidthings/sample-button. 回答1: This means another app is running in the background and is currently accessing this pin. This may happen if one app is not fully stopped before a new one is opened. You can see all your installed apps by running: adb shell pm list
