我可以像下面这样获得当前设备支持的语言环境列表：
for (Locale each : Locale.getAvailableLocales())
if(1 <= myTTS.isLanguageAvailable(each))
supportedLocales.add(each);
但是我的问题是，方法
isLanguageAvailable()总是记录不支持的语言环境的警告消息，如下所示：08-15 20:10:08.163 5056 5672 W TTS Local voice not installed, we will not be able to do local fallback

每当我启动我的TTS应用程序时，我都会收到很多这样的东西，但我真的不想这么做。
对于我的发行版，如何抑制这些不必要的警告消息？
最佳答案
一种解决方法是将logcat筛选器设置为除TextToSpeech之外的所有内容（您需要启用正则表达式）：^((?! TextToSpeech).)*$
我认为您无法对来自核心api的日志做任何事情。当您从某些电话进行调试并始终获取蓝牙或连接日志时，也会出现相同的问题。
