如何在打ze模式下将清单白名单应用Android 6.0

Question

这个问题与将于本月底最终发布的Android 6.0 Preview 3有关。

我正在Nexus 5“ hammerhead”上通过Google在预览版3中测试Android 6.0中的某些功能。

新功能是“打mode模式”-类似于深度睡眠模式（当网络被禁用且电话处于睡眠状态时），只有SMS，电话或高优先级GCM消息才能将其唤醒。但是像WhatsApp一样-在打ze模式下，它会在2小时或更长时间后接收消息，具体取决于计时器。但是，有一个名为“白名单”的“未优化”应用程序列表，您可以在其中手动添加应用程序。

好的，我想找到一种方法，以编程方式将我的应用程序添加到电池设置中设备中存在的“白名单应用程序列表”中，而无需用户交互。

尝试使用反射进入它，我发现：

在android.os.IDeviceIdleController中，有一个方法：

公共抽象无效addPowerSaveWhitelistApp（字符串packageNameOfApp）

但这是一个接口...因此，我们无法创建接口的实例。

尚无有关此接口，方法或任何继承树的文档。

也许您有一些想法，我应该在哪里寻找以编程方式添加我的应用程序的可能性？

还有一种方法

公共抽象布尔isPowerSaveWhitelistApp（字符串packageName）

我认为应该可以以某种方式访问哪个？检查该应用程序是否存在于白名单中，并且可能最终希望ASK用户将其添加到白名单中。

所以我的问题是，你们当中有人尝试过做出更好的结果吗？因为我被卡住了，我认为这是一个死胡同。

Answer 1

添加权限<uses-permission&nbsp;android:name="android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS"/>请求将您的应用列入白名单&nbsp;if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Intent intent = new Intent();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; String packageName = getPackageName();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; PowerManager pm = (PowerManager) getSystemService(POWER_SERVICE);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if (!pm.isIgnoringBatteryOptimizations(packageName)) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; intent.setAction(Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; intent.setData(Uri.parse("package:" + packageName));&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; startActivity(intent);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; }

Answer 2

如果没有在Android M预览版3上进行用户交互，则无法禁用电池优化（=打ze模式的白名单应用程序）。可以通过以下方式与用户交互来完成：Intent intent = new Intent();String packageName = context.getPackageName();PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);if (pm.isIgnoringBatteryOptimizations(packageName))&nbsp; &nbsp; intent.setAction(Settings.ACTION_IGNORE_BATTERY_OPTIMIZATION_SETTINGS);else {&nbsp; &nbsp; intent.setAction(Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS);&nbsp; &nbsp; intent.setData(Uri.parse("package:" + packageName));}context.startActivity(intent);

我认为该帮助班应该满足您的所有需求。要使用它来请求操作系统将您的应用列入白名单，您可以使用prepareIntentForWhiteListingOfBatteryOptimization。如果您得到null，则表示您不需要它或无法使用它。您可以使用其他功能查询您所处状态的更好状态。public class PowerSaverHelper {&nbsp; &nbsp; public enum PowerSaveState {&nbsp; &nbsp; &nbsp; &nbsp; ON, OFF, ERROR_GETTING_STATE, IRRELEVANT_OLD_ANDROID_API&nbsp; &nbsp; }&nbsp; &nbsp; public enum WhiteListedInBatteryOptimizations {&nbsp; &nbsp; &nbsp; &nbsp; WHITE_LISTED, NOT_WHITE_LISTED, ERROR_GETTING_STATE, UNKNOWN_TOO_OLD_ANDROID_API_FOR_CHECKING, IRRELEVANT_OLD_ANDROID_API&nbsp; &nbsp; }&nbsp; &nbsp; public enum DozeState {&nbsp; &nbsp; &nbsp; &nbsp; NORMAL_INTERACTIVE, DOZE_TURNED_ON_IDLE, NORMAL_NON_INTERACTIVE, ERROR_GETTING_STATE, IRRELEVANT_OLD_ANDROID_API, UNKNOWN_TOO_OLD_ANDROID_API_FOR_CHECKING&nbsp; &nbsp; }&nbsp; &nbsp; @NonNull&nbsp; &nbsp; public static DozeState getDozeState(@NonNull Context context) {&nbsp; &nbsp; &nbsp; &nbsp; if (VERSION.SDK_INT < VERSION_CODES.LOLLIPOP)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return DozeState.IRRELEVANT_OLD_ANDROID_API;&nbsp; &nbsp; &nbsp; &nbsp; if (VERSION.SDK_INT < VERSION_CODES.M) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return DozeState.UNKNOWN_TOO_OLD_ANDROID_API_FOR_CHECKING;&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; final PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);&nbsp; &nbsp; &nbsp; &nbsp; if (pm == null)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return DozeState.ERROR_GETTING_STATE;&nbsp; &nbsp; &nbsp; &nbsp; return pm.isDeviceIdleMode() ?
