android8.0很多广播不能静态注册接受

查看log显示 Background execution not allowed: receiving

查看代码frameworks/base/services/core/java/com/android/server/am/BroadcastQueue.java

if (!skip) {

final int allowed = mService.getAppStartModeLocked(

info.activityInfo.applicationInfo.uid, info.activityInfo.packageName,

info.activityInfo.applicationInfo.targetSdkVersion, -1, true, false);

if (allowed != ActivityManager.APP_START_MODE_NORMAL) {

// We won't allow this receiver to be launched if the app has been

// completely disabled from launches, or it was not explicitly sent

// to it and the app is in a state that should not receive it

// (depending on how getAppStartModeLocked has determined that).

if (allowed == ActivityManager.APP_START_MODE_DISABLED) {

Slog.w(TAG, "Background execution disabled: receiving "

+ r.intent + " to "

+ component.flattenToShortString());

skip = true;

} else if (((r.intent.getFlags()&Intent.FLAG_RECEIVER_EXCLUDE_BACKGROUND) != 0)

|| (r.intent.getComponent() == null

&& r.intent.getPackage() == null

&& ((r.intent.getFlags()

& Intent.FLAG_RECEIVER_INCLUDE_BACKGROUND) == 0)

&& !isSignaturePerm(r.requiredPermissions))) {

mService.addBackgroundCheckViolationLocked(r.intent.getAction(),

component.getPackageName());

Slog.w(TAG, "Background execution not allowed: receiving "

+ r.intent + " to "

+ component.flattenToShortString());

skip = true;

}

}

}

所以我们要发送能静态注册接受的广播可以设置ComponentName,PackageName,或者设置FLAG_RECEIVER_INCLUDE_BACKGROUND 这个标志位

设置ComponentName,PackageName就只有指定的应用能接受这个广播,

/**

*

* @hide

*/

public static final int FLAG_RECEIVER_INCLUDE_BACKGROUND = 0x01000000;

这个FLAG是hide的,所以我们能设置intent.addFlags(0x01000000);去让广播能静态注册接受.
