}3. 源码走读-关联自启动的逻辑
如之前的走读记录，上层主要是通过界面完成黑白名单的设置，写入 AppPowerSaveConfig 中，故接下来的重点是查看 AppPowerSaveConfig 中尤其是关联自启动白名单调用的逻辑事件
3.1 AppPowerSaveConfig
- vendor/sprd/platform/frameworks/base/core/java/android/os/AppPowerSaveConfig.java
package android.os;
public class AppPowerSaveConfig implements Parcelable{
private static final String APPCONFIG_FILENAME = "appPowerSaveConfig.xml";
// 构造器
public AppPowerSaveConfig() {
for (int i=0; i<ConfigType.TYPE_MAX.value; i++) {
setConfigWithType(this , i, mDefConfig[i]);
}
}
// 类型
public enum ConfigType {
TYPE_NULL(-1),
TYPE_OPTIMIZE(0), // 电池优化总开关
TYPE_ALARM(1), // 对齐唤醒
TYPE_WAKELOCK(2), // 待机优化
TYPE_NETWORK(3), // 网络
TYPE_AUTOLAUNCH(4),// 自启动
TYPE_SECONDARYLAUNCH(5), // 关联唤醒
TYPE_LOCKSCREENCLEANUP(6), // 锁屏后清理
TYPE_POWERCONSUMERTYPE(7), // 耗电情况，GPS耗电，长时间持锁、频繁唤醒
TYPE_MAX(8);
public final int value;
private ConfigType(int value){
this.value = value;
}
}其中上述配置文件的存放位置
- /data/system/appPowerSaveConfig.xml

</app_powersave_config>3.2 查看 AppPowerSaveConfig的调用情况，尤其是secondLaunch的调用
全局搜索发现如下只有 BackgroundCleanHelper.java 比较靠谱，但是没有看到AMS\Broadcast相关，查询记录如下

上述主要为了dump出白名单调用-关联唤醒相关 2

boolean bInBlackList = false;
// 黑名单
if ((autoLaunch == AppPowerSaveConfig.VALUE_OPTIMIZE)

}调用-关联唤醒相关 3

if ((secondLaunch == AppPowerSaveConfig.VALUE_OPTIMIZE) && launchByOther) {
if (DEBUG_MORE) Slog.d(TAG, "in apppowerconfig 2ndlaunch black list: " + targetApp);
bInBlackList = true;
}上述中 checkLaunchStateByUserSetting 为被 judgeAppLaunchAllowedInternal 唯一调用
3.3 查看 judgeAppLaunchAllowedInternal 及其被调用关系
看了描述这里很清晰了，这个就是判断是否要拦截应用启动的核心函数

* 2. not allow start service from ""com.android.shell"
* 3. not allow background app to launch other third party app
* 4. not allow self started third party app to start other third party app
* 5. not allow third party app to start other third party app during standby
*
* Note: This api is call from AMS in other threads and may be in variable calling context
* SO BE CAREFULL : avoid call other system API that may hold lock. Otherwise, a deadlock may HAPPEN
