One of my apps was executing a native C file using exec command which is no longer supported (in Android Q or above) if executed from within the application home directory as shown in the post below:

The suggestion is to put the file in libs folder so that Android extracts during runtime then I can run the command from the directory:

B4X:

context.getApplicationInfo().nativeLibraryDir + "/" + NativeFileName;

I wanted to know how I can put the file in libs folder

ok. I had tried that but the file was still not found during runtime. The code

B4X:

File libDirectory = new File(context.getApplicationInfo().nativeLibraryDir);
String files[] = libDirectory.list();

always returns an empty list during runtime, though i thought the libraries will be in nativeLibraryDir
