There is the Error 802 which has appeared in the app created in 2018. I think the problem may be from the setting of Sound Recorder. Might there have been any change of setting which makes the previous built apps not works? Would there be any solution on it?
Even I have typed the absolute path and name of the saved recording data to solve the Error 804, another error code comes:
ERROR 701:Unable to load /storage/emulated/0/Download/recording.3gp
