iMX8QM Android Automotive OS Root Permission Error

cbl — Mon, 16 Jan 2023 13:04:23 GMT

Hello,

I compiled Android Automotive OS 10 with userdebug build option for NXP iMX8QM.

I need to give root privileges by running the "su" command from within the APK that I developed with Android Studio.

public static void sudo(String... strings) { try { Process su = Runtime.getRuntime().exec("su"); DataOutputStream outputStream = new DataOutputStream(su.getOutputStream()); for (String s : strings) { outputStream.writeBytes(s + "\n"); outputStream.flush(); } outputStream.writeBytes("exit\n"); outputStream.flush(); try { su.waitFor(); } catch (InterruptedException e) { e.printStackTrace(); } outputStream.close(); } catch (IOException e) { e.printStackTrace(); } }

I am using the code block below to do this. But I get the error "W/System.err: java.io.IOException: Cannot run program "su": error=13, Permission denied".

What should I do in this situation, could you please help me this issue?

Best regards,

Efecan

Hello,

Looks like the problem is in the host setup for su, the password of the BSP is "root".

Hi @Bio_TICFSL,

When I run the "su" command from the console of Android Automotive OS, I become root.

I want to do this with the APK I developed, but I can't.

As I said above, when I send the "su" command from within the APK, I get a "permission denied" error in the Android Studio console.

Best regards,

Efecan
