Will this app appear on the Play Store?

Question

I have heard in many places that if my application uses a resolution that is not applicable to a specific device, it will not appear in the playback store for that device. Now, in my code, I play audio. I will mute this sound when there is a phone call by doing this:

 private PhoneStateListener phoneStateListener = new PhoneStateListener() {
        @Override
        public void onCallStateChanged(int state, String incomingNumber) {
                if (state == TelephonyManager.CALL_STATE_RINGING) {
                    onPhoneCallInterrupt(); //Method I made that mutes audio for phone call
                } else if (state == TelephonyManager.CALL_STATE_IDLE) {
                } else if (state == TelephonyManager.CALL_STATE_OFFHOOK) {
                    onPhoneCallInterrupt(); //Method I made that mutes audio for phone call
                }
        }
    };

The manifest now uses the following permission:

<uses-feature android:name="android.permission.READ_PHONE_STATE"  android:required="false" />

Will I get exceptions because I made the resolution optional by running android:required = "false"on devices that do not support phone compatibility (tablets)?

The reason I am so confused about this is because I am checking if the phone is being used, but I am not using it. So, will my application work on tablets, not to mention the appearance in the store for them?

    return retval;
}
