Permission Error in Android Device
-
Hello,
I am quite new to Android app development. I had a Window app developed on Qt for serial port. I cross-compiled it for Android phone. It successfully build and run on Android Phone as well, but when I try to connect to the available serial Port I got an error saying - "Permission Error: Unable to create Lock file." I cross verified with other available Google Play store app for serial port, it is working fine with it.
I tried google for similar issue, I got some reference but unable to fix the issue. Please let me know if anyone have simpler & straightforward way of fixing it.
Thanks

QSP does not supported on Android in common case. It can work (theoretically) only with the rooted Android devices, when an application starts with the root rights.
I want to say, that this "Permission Error: Unable to create Lock file." maybe can be fixed by modification of the QSP sources. But, next you will got a new error, related to permission rights for opening of device.
