How to run adb command in Android Studio sourcecode? [duplicate]-CodePudding

        muteButton.setOnClickListener {
            Runtime.getRuntime().exec("adb shell settings put system csc_pref_camera_forced_shuttersound_key 0");
        }

This is my code, and below is Log message.

    java.lang.RuntimeException: java.lang.reflect.InvocationTargetException

I think

Caused by: java.io.IOException: Cannot run program "adb": error=13, Permission denied

is a cause. How should I modify my code?

CodePudding user response：

The adb command is a program which is installed on your PC and it opens a shell in the android device. If you use native code, you don't need (and cannot) to use it - just remove it and call the command directly:
Runtime.getRuntime().exec("settings put system csc_pref_camera_forced_shuttersound_key 0");
