Doze 模式列表

上述备注规则如下

if(powerWhitelist.isSysWhitelisted(pkg)) {// Summary of app which doesn't have a battery optimization setting
    show:Battery optimization not available
} else {if(powerWhitelist.isWhitelisted(pkg)) {// Summary of app allowed to use a lot of power
    show:Not optimized} else {// Summary of app which doesn't have a battery optimization setting
    show:Optimizing battery use}
}

• 由于Android O 解耦的思想，上述源码即如下路径

1.RootDirectory 
etc/sysconfig/ 
etc/permissions/

我的机器没有etc/sysconfig/路径
Z50:/etc/permissions # ls
ls
android.software.live_wallpaper.xml  mediatek-packages-teleservice.xml

• 2.VendorDirectory

• 3.OdmDirectory

odm/etc/sysconfig/ 
odm/etc/permissions/

很可惜，都没有，这里主要给ODM自己建立对应文件夹进行配置
2|Z50:/ # ls
ls
acct       data             init.preload.rc      nvdata    sdcard

d          init.environ.rc  nvcfg                sbin

• 3.oemDirectory

oem/etc/sysconfig/ 
oem/etc/permissions/

没有具体文件
Z50:/oem # ls
ls

• 具体文件

具体源码

    void readPermissions(File libraryDir, int permissionFlag) {// Read permissions from given directory.if (!libraryDir.exists() || !libraryDir.isDirectory()) {if (permissionFlag == ALLOW_ALL) {Slog.w(TAG, "No directory " + libraryDir + ", skipping");}return;}if (!libraryDir.canRead()) {Slog.w(TAG, "Directory " + libraryDir + " cannot be read");return;}// Iterate over the files in the directory and scan .xml filesFile platformFile = null;for (File f : libraryDir.listFiles()) {// We'll read platform.xml last// 这个文件最后会读的if (f.getPath().endsWith("etc/permissions/platform.xml")) {platformFile = f;continue;}if (!f.getPath().endsWith(".xml")) {Slog.i(TAG, "Non-xml file " + f + " in " + libraryDir + " directory, ignoring");continue;}if (!f.canRead()) {Slog.w(TAG, "Permissions library file " + f + " cannot be read");continue;}readPermissionsFromXml(f, permissionFlag);}// Read platform permissions last so it will take precedence// 我就是最后if (platformFile != null) {readPermissionsFromXml(platformFile, permissionFlag);}}

• 接下来很明显就是读取各种XML了

private void readPermissionsFromXml(File permFile, int permissionFlag) {
我们重点关注下面的即可
...} else if ("allow-in-power-save-except-idle".equals(name) && allowAll) {String pkgname = parser.getAttributeValue(null, "package");if (pkgname == null) {Slog.w(TAG, "<allow-in-power-save-except-idle> without package in "+ permFile + " at " + parser.getPositionDescription());} else {mAllowInPowerSaveExceptIdle.add(pkgname);}XmlUtils.skipCurrentTag(parser);continue;} else if ("allow-in-power-save".equals(name) && allowAll) {String pkgname = parser.getAttributeValue(null, "package");if (pkgname == null) {Slog.w(TAG, "<allow-in-power-save> without package in " + permFile + " at "+ parser.getPositionDescription());} else {mAllowInPowerSave.add(pkgname);}XmlUtils.skipCurrentTag(parser);continue;
...

• 取出白名单

手机路径 /etc/permissions/platform.xml

对应源代码路径如下

    <!-- These are the standard packages that are white-listed to always have internetaccess while in power save mode, even if they aren't in the foreground. --><allow-in-power-save package="com.android.providers.downloads" /><!-- This is a core platform component that needs to freely run in the background --><allow-in-power-save package="com.android.cellbroadcastreceiver" /><allow-in-power-save package="com.android.shell" />

• 系统源码路径 frameworks\base\data\etc\platform.xml

当然内容是一样的啦<!-- These are the standard packages that are white-listed to always have internetaccess while in power save mode, even if they aren't in the foreground. --><allow-in-power-save package="com.android.providers.downloads" /><!-- This is a core platform component that needs to freely run in the background --><allow-in-power-save package="com.android.cellbroadcastreceiver" /><allow-in-power-save package="com.android.shell" />

• 手机路径 /vendor/etc/permissions/抱歉这里没有

系统源码路径 vendor\mediatek\proprietary\frameworks\base\data\etc\抱歉这里也没有，需要自行配置

系统源码路径 \vendor\partner_gms\etc\sysconfig\google.xml

这里是亲爱的Gms包设置Line 23:     <allow-in-power-save package="com.google.android.gms" />Line 28:     <allow-in-power-save-except-idle package="com.google.android.apps.work.oobconfig" />Line 41:     <allow-in-power-save-except-idle package="com.android.vending" />Line 44:     <allow-in-power-save package="com.google.android.volta" />Line 48:     <allow-in-power-save package="com.google.android.ims" />

• 软件接口设置

    // Doze 模式新增白名单public void addApp(String pkg) {try {mDeviceIdleService.addPowerSaveWhitelistApp(pkg);mWhitelistedApps.add(pkg);} catch (RemoteException e) {Log.w(TAG, "Unable to reach IDeviceIdleController", e);}}// Doze 模式移除白名单public void removeApp(String pkg) {try {mDeviceIdleService.removePowerSaveWhitelistApp(pkg);mWhitelistedApps.remove(pkg);} catch (RemoteException e) {Log.w(TAG, "Unable to reach IDeviceIdleController", e);}}

• 软件接口的配置也会体现这这个路径下

data/system/deviceidle.xml

Z50:/data/system # cat deviceidle.xml
cat deviceidle.xml
<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<config>
<wl n="com.google.android.apps.maps" />
<wl n="com.google.android.gsf" />
</config>

• 具体相关源码

 public final AtomicFile mConfigFile;public DeviceIdleController(Context context) {super(context);mConfigFile = new AtomicFile(new File(getSystemDir(), "deviceidle.xml"));mHandler = new MyHandler(BackgroundThread.getHandler().getLooper());}

• 总结

Doze模式的白名单我们可以预设置还可以进行软件接口调用。 
1.主要预设置在 
frameworks\base\data\etc\platform.xml 
随着Android O 的代码控制雄心，以后路径可能需要厂商自己定义 
vendor\mediatek\proprietary\frameworks\base\data\etc\platform.xml

2.不要忘记GMS包里面也可以配置的 
\vendor\partner_gms\etc\sysconfig\google.xml

3.接口调用同样Google提供给我们了，使用起来同样简单粗暴，查看设置结果 data/system/deviceidle.xml
