無法在應用程序啓動時調用廣播接收器

Question

您好，我一直在試圖創建一個廣播接收器，但我無法調用它，即從應用程序啓動時啓動它，這裏是我的代碼，請告訴我，是否有東西丟失或不在這裏是我嘗試到現在爲止的事情

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.testing.broacast" android:versionCode="1" android:versionName="1.0" android:installLocation="auto"> 
<uses-sdk android:minSdkVersion="16" /> 
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" /> 
<application android:label="App4"></application> 
<receiver android:name=".Broadcast"> 
    <intent-filter> 
     <action android:name="android.intent.action.BOOT_COMPLETED" /> 
    </intent-filter> 
</receiver> 
</manifest> 

這裏是我的廣播reciever

[BroadcastReceiver] 
[IntentFilter(new[] { Intent.ActionBootCompleted })] 


public class Broadcast : BroadcastReceiver 
{ 
    public override void OnReceive(Context context,Intent intent) 
    { 

      Toast.MakeText(context, "Hello", ToastLength.Long).Show(); 
      // Create your application here} 

    } 
} 

Answer 1

這是如何工作的我的設備上

[BroadcastReceiver(Enabled = true)] 
[IntentFilter(new[] { Intent.ActionBootCompleted })] 
public class Broadcast : BroadcastReceiver 
{ 
    public override void OnReceive(Context context, Intent intent) 
    { 
     Toast.MakeText(context, "Hello", ToastLength.Long).Show(); 
    } 
} 

不同的是[BroadcastReceiver(Enabled = true)]

而且我也沒必要把receiver標籤在我AndroidManifest.xml。
