It is said in renpy
documentation and I quote:
If you don't want to download the SDK each time, you can create a file named sdk.txt containing a single line that is the path to the already-installed SDK
The problem is that, after I create the file with the content going to the Android SDK parent path, the renpy
GUI Android still needs to download Android SDK(did not see the pre-installed Android SDK). I cannot access the configuration button when it cannot see the Android SDK installed path.
Note: I checked the Android SDK path and it is correct. D:\android-sdk\
