try
{
   //Get list of input methods
   List InputMethods=((InputMethodManager)myActivity.getSystemService(Context.INPUT_METHOD_SERVICE)).getEnabledInputMethodList();

   String nameIME = InputMethods.get(0).getServiceName();
   Log.i("Demo Error", "SWITCHING TO: "+nameIME);
   String NewInputMethodName=InputMethods.get(0).getId(); //Pick the first input method to switch to
   Log.i("Demo Error", "SWITCHING TO: "+NewInputMethodName);
   String curInputMethodId = Settings.Secure.getString(myActivity
       .getContentResolver(), Settings.Secure.DEFAULT_INPUT_METHOD);
   Log.i("Demo Error", "CURRENT IME: "+curInputMethodId);

   // Solution 1 (X)
   // switchInputMethod is a method of android.inputmethodservice.InputMethodService
//   switchInputMethod(NewInputMethodName); //This throws an error

   // Solution 2 (OK)
   Settings.Secure.putString(myActivity.getContentResolver(),
   Settings.Secure.DEFAULT_INPUT_METHOD, NewInputMethodName);

   // Solution 3 (OK)
   if (myActivity.checkCallingOrSelfPermission(
       android.Manifest.permission.WRITE_SECURE_SETTINGS)
                        != 0) {
                   // PERMISSION_GRANTED == 0
           Log.i("Demo Error", "myActivity requires permission "
               + android.Manifest.permission.WRITE_SECURE_SETTINGS);
   }

   ((InputMethodManager)myActivity.getSystemService(Context.INPUT_METHOD_SERVICE))
       .setInputMethod(null, NewInputMethodName);


   // Show SoftInput Keyboard
   EditText inputText = (EditText)myActivity.findViewById(R.id.inputText);
   ((InputMethodManager)myActivity.getSystemService(Context.INPUT_METHOD_SERVICE))
       .showSoftInput(inputText, 0);

} catch(Exception e) {
   Log.i("Demo Error", e.getMessage());
