Android - Input Text within app doesn't work

I'm trying to input text into the current running application (not my own) using the adb input text method, this works if I run it from the command prompt such as 'adb input text "Android" and also if I run it from terminal emulator. However the below code run successfully but produces no output on the screen.. I have also tried various other methods to run shell commands which have also not failed but not output any text.. Anyone know what I am doing wrong?

try {
            //Runtime.getRuntime().exec("su");
            Runtime.getRuntime().exec("input text \":\"");
        } catch (IOException e) {
            e.printStackTrace();
        }
Solution

  • To inject text into an android app the injector must have 

       android.permission.INJECT_EVENTS

    permission, so it must be a system app.

    Your Runtime.getRuntime().exec has not this permission.
