在 AndroidManifest.xml 文件中配置一下权限

<uses-permission android:name="android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS" />

加入白名单工具类

使用

if (!AlwaysLive.isIgnoringBatteryOptimizations(this)){AlwaysLive.requestIgnoreBatteryOptimizations(this);}

使用2：通过测试发现以下方法不能使用，会出现崩溃现象

if (!AlwaysLive.isIgnoringBatteryOptimizations(this))AlwaysLive.gotoWhiteListSetting(this);
