Execute file from Android device programatically
I have finished my Chess UI application and now want to load a chess engine to test if my UI truly is UCI-compatible. The chess engine is inside the Download folder of the Android device ('/storage/emulated/0/Download'). This is the code that is run:
try {
File f = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
String path = f.getAbsolutePath();
String stockfishPath = path + "/Stockfish-9-armv64v8";
engineProcess = Runtime.getRuntime().exec(stockfishPath);
processReader = new BufferedReader(new InputStreamReader(
engineProcess.getInputStream()));
String sCurrentLine;
ArrayList<String> output = new ArrayList<>();
while ((sCurrentLine = processReader.readLine()) != null) {
output.add(sCurrentLine);
}
processWriter = new OutputStreamWriter(
engineProcess.getOutputStream());
} catch (Exception e) {
e.printStackTrace();
}
When I run this it fails on the exec() method because it claims it cannot find the file, even though the file exists on the Android device. I tried running the "ls" command on the exec() method, but the folder inside "emulated" is empty. The obvious reason for this is probably because I do not have permission to view/access these files, but I need to know how I can do that (despite adding the READ_EXTERNAL_STORAGE and WRITE_EXTERNAL_STORAGE in the manifest file).
Is it maybe possible to embed the engine somewhere in the project (in resources?) and somehow adb-shell into that?

you cannot do that, simply because the SD card is being mounted with -noexec flag.
using the internal storage with chmod +x would be the only option available.

@DanZoe this is not the internal storage; just see how often you've used the word external above. usegetFilesDir().getAbsolutePath()and.exec("chmod +x " + stockfishPath). while it possibly might not run without root, because the SE Linux labels could prevent it from doing so - and unless being root, there is nosemanagecommand available to label the file.

I see. Is there another way of executing the stockfish executable. I have searched and searched, and the only thing I need, is to actually execute it, no matter the location. Do you have any tips?

@DanZoe have you tried the suggested method yet? "I see" does not exactly sound alike.
