无法运行程序“adb”：错误=13，权限被拒绝

Question

I have a program, which must execute only one command

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        Runtime.getRuntime().exec("adb shell input tap 0 0")
    }
}

But I'm getting an error

Process: com.example.tomfo.pokerclicker, PID: 11578
java.io.IOException: Cannot run program "adb": error=13, Permission denied

Although I've added adb to path into properties on Windows and can run abd commands throw Android Studio console (but in Android Studio console command is not green). How to solve this problem? This command is working throw Studio console command

Answer 1

adb is a tool you use on your computer, "adb shell" opens a shell on the device (or emulator), and "adb shell command" runs the command on it.

So if you want to run the command programmatically on the device, just remove "adb shell":

Runtime.getRuntime().exec("input tap 0 0")

Answer 2

I got it like this

 fun commandAdb() {
    InstrumentationRegistry.getInstrumentation().uiAutomation.executeShellCommand("svc wifi disable")
    InstrumentationRegistry.getInstrumentation().uiAutomation.executeShellCommand("svc data disable")
}
