[안드로이드 TTS 관련 오류]ActivityNotFoundException : Unable to find explicit activity class {com.android.settings/com.android.settings.TextToSpeechSettings}; have you declared this activity in your AndroidManifest.xml?

새로운 오류가 보고 되었다. 오류는 구글픽셀2폰에서 발생된 것으로 확인되었다. 픽셀2폰이 마침 나에게 있다. 

그러나 오류는 재현되지 않았다. 

Fatal Exception: java.lang.RuntimeException: Unable to start activity ComponentInfo{com.manage.MainActivity}: android.content.ActivityNotFoundException: Unable to find explicit activity class {com.android.settings/com.android.settings.TextToSpeechSettings}; have you declared this activity in your AndroidManifest.xml?

안드로이드 11이 설치된 픽셀2폰에서는 TTS관련 설정 액티비티가 존재하지 않는 것일까?

오류가 발생한 코드는 다음과 같다.

public void callTTSettingClicked(View v){
	try {

		// Unable to find explicit activity class {com.android.settings/com.android.settings.TextToSpeechSettings}; have you declared this activity in your AndroidManifest.xml?
		//        ComponentName componentToLaunch = new ComponentName(
		//                "com.android.settings",
		//                "com.android.settings.TextToSpeechSettings");
		//        Intent intent = new Intent();
		//        intent.addCategory(Intent.CATEGORY_LAUNCHER);
		//        intent.setComponent(componentToLaunch);
		//        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
		//        startActivity(intent);

		Intent intent = new Intent();
		intent.setAction("com.android.settings.TTS_SETTINGS");
		intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
		startActivity(intent);

		//        Intent intent = new Intent();
		//        intent.addCategory(Intent.CATEGORY_LAUNCHER);
		//        intent.setComponent(new ComponentName("com.android.settings", "com.android.settings.TextToSpeechSettings"));
		//        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
		//        startActivity(intent);
	}catch (Exception e) {
		Toast.makeText(TTSActivity.this, getResources().getString(R.string.cont_24), Toast.LENGTH_LONG).show();
	}
}
