1、 首先再AndroidMainfest.xml里配置

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

2、使用代码

/**
    * 忽略电池优化
    */
   private void ignoreBatteryOptimization(Activity activity) {
       if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
           PowerManager powerManager = (PowerManager) getSystemService(POWER_SERVICE);

           boolean hasIgnored = powerManager.isIgnoringBatteryOptimizations(activity.getPackageName());
           //  判断当前APP是否有加入电池优化的白名单，如果没有，弹出加入电池优化的白名单的设置对话框。
           if (!hasIgnored) {
               Intent intent = new Intent(Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS);
               intent.setData(Uri.parse("package:" + activity.getPackageName()));
               if (intent.resolveActivity(getPackageManager()) != null) {
                   startActivity(intent);
               }
           } else {
               Log.d("ignoreBattery", "hasIgnored");
           }
       }
   }
