Clone USB Keyboard App to Android Studio

[luke-par]

Hello, I would like to load the source code of the USB Keyboard app into Android Studio(Windows). I have cloned the git repository (https://github.com/pelya/commandergenius.git), but the app cannot be compiled. (Compilation button greyed out). Unfortunately I haven't used Git yet and I'm not familiar with it.

Can you help me?

Thanks for your help in advance.

That would be very complicated. The app itself is written in C++ and won't compile on Windows.

Thanks for your quick answer.

Is it possible to send the commands directly to the shell (with the help of the hid-gadget-test)? I tried the following code, but unfortunately it doesn't work. But if I insert the commands in a terminal under Android it works without problems.

`import android.support.v7.app.AppCompatActivity; import android.os.Bundle;

import android.view.View; import android.widget.Button;

import java.io.IOException;

public class MainActivity extends AppCompatActivity {

Button button;

Process shellprocess;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    button = findViewById(R.id.button);

    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            try {

                shellprocess = Runtime.getRuntime().exec("su");
            } catch (IOException e) {
                e.printStackTrace();
            }
            try {
                shellprocess = Runtime.getRuntime().exec("echo a | /data/local/tmp/hid-gadget-test /dev/hidg0 keyboard");
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    });

}

} ` Permissions: Write read/write internal and external storage

Thanks for your help.

That would work, but you need to do 'su -c hid-gadget-test ...' because your code is creating two independent shell processes like that.

        } catch (IOException e) {

        }
    }
});

}

} `

Thanks for your help.

Can you paste the full command please? Thanks

[pelya]

This one should work:

echo left-shift b | su /data/local/tmp/hid-gadget-test /dev/hidg0 keyboard

I got the error: Unknown id: /data/local/tmp/hid-gadget-test

[luke-par]

I got it. The right command is: su -c "echo left-shift b | ./data/local/tmp/hid-gadget-test /dev/hidg0 keyboard"

Thanks

Note: on emulator the 'su' command does not accept -c argument, but I think most rooted devices have more advanced version of 'su' so your code should work okay.
