atal Exception: java.lang.IndexOutOfBoundsException setSpan (4 ... 4) ends beyond length 3 only occuring on Nexus 5X devixes

Question

I see this crash for a while now in my crashlytics and I cannot find a way to fix it. It only occurs on Nexus 5X devices with Android 6.0.1.

Crashlog:

I cannot reproduce the crash. Neither with a physical device nor with the emulator. It seems to have something to do with the TextChanged listener. It crashes when this gets executed.

Code Example:

        editTextCotton.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {

            }

            @Override
            public void afterTextChanged(Editable s) {
                calculateRaidLevel();
            }
        });


public void calculateRaidLevel(){

    double CROP_VALUE_COTTON = 1.5;

    double cropValue;

    int cottonValue = 0;
    if(!editTextCotton.getText().toString().isEmpty())           cottonValue = Integer.valueOf(editTextCotton.getText().toString());

    cropValue =  cottonValue * CROP_VALUE_COTTON;

}
