檢查運行時清單中是否聲明瞭BroadcastReceiver？

Question

有沒有辦法在運行時檢查清單中聲明瞭哪些BroadcastReceivers？

Answer 1

謝謝，但不是我的本意。我想獲得知道，如果一個特定的接收器在運行的應用程序中聲明運行時，取得這樣說：

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()找到誰將回應一個特定的Intent和getInstalledPackages()，你可以找到每個包安裝的接收器。

Answer 3

的代碼會是這樣的相似，從活動中：

// 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... 
    } 
}

傳入應用程序對象作爲第一個參數，你可以做到這一點與(Application)context.GetApplicationContext()如果你有，那麼你的類，它實現了廣播接收器類作爲第二通論點例如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; 
}
