Is it possible to install an apk without user intervention by putting prompt commands in the codeword or something?

Question

Actually, it’s update I need to do, does anyone know if it’s possible to do this without user intervention? I just inform that there is an update close the application and update alone. I thank you from now.

Only possible on routine devices.

    public static boolean InstallAPK(String filename)
    {
        File file = new File(filename);
        if(file.exists())
