检查运行时清单中是否声明了BroadcastReceiver？

Question

有没有办法在运行时检查清单中声明了哪些BroadcastReceivers？

Answer 1

谢谢，但不是我的本意。我想获得知道，如果一个特定的接收器在运行的应用程序中声明运行时，取得这样说：

private <Receiver extends CyborgReceiver<?>> boolean checkIfBroadcastReceiverIsRegisteredInManifest(Class<Receiver> receiverType) { 
    PackageManager pm = application.getPackageManager(); 
    try { 
     ActivityInfo info = pm.getReceiverInfo(new ComponentName(application, receiverType), PackageManager.GET_RECEIVERS); 
     return info.enabled; 
    } catch (NameNotFoundException e) { 
     return false; 
    } 
} 

Answer 2

使用PackageManager，你可以queryBroadcastReceivers()找到谁将回应一个特定的Intent和getInstalledPackages()，你可以找到每个包安装的接收器。

Answer 3

的代码会是这样的相似，从活动中：

// Query all packages that have the BroadcastReceivers... 
Intent mainIntent = new Intent(Intent.ACTION_MAIN, null); 
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER); 
PackageManager pm = getPackageManager(); 
final List<ResolveInfo> listPkgs = pm.queryBroadcast(mainIntent, 0); 
if (listPkgs != null && listPkgs.size() > 0){ 
    for(ResolveInfo resInfo : listPkgs){ 
     // Now resInfo will contain the list of packages that has receivers... 
    } 
}

传入应用程序对象作为第一个参数，你可以做到这一点与(Application)context.GetApplicationContext()如果你有，那么你的类，它实现了广播接收器类作为第二通论点例如broadcastReceiver.class

public static boolean validateReceiverInManifest(Application application, Class receiverClass) throws PackageManager.NameNotFoundException { 
    PackageManager pm = application.getPackageManager(); 
    String packageName = application.getPackageName(); 

    PackageInfo packageInfo = pm.getPackageInfo(packageName, PackageManager.GET_RECEIVERS); 
    ActivityInfo[] receivers = packageInfo.receivers; 
    String receiverClassName = receiverClass.getName(); 
    for (ActivityInfo activityInfo : receivers) { 
     if (activityInfo.name.equals(receiverClassName)) { 
      return true; 
     } 
    } 
    return false; 
}
