BroadcastReceiver不工作

Question

我已经加入AndroidManifest.xml，我认为每分钟都会记录日志的标记“CWCGR1”。 但没有发生，似乎onReceive()不运行，我的应用程序有什么错误？谢谢！

的AndroidManifest.xml：

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example.enabledisablebroadcastreceiver" 
    android:versionCode="1" 
    android:versionName="1.0" > 
    <uses-sdk 
     android:minSdkVersion="15" 
     android:targetSdkVersion="15" /> 
    <application 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" 
     android:theme="@style/AppTheme" > 
     <activity 
      android:name="com.code4reference.enabledisablebroadcastreceiver.EnableDisableBroadcastReceiver" 
      android:label="@string/title_activity_enable_disable_boradcast_receiver" > 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 
       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity> 

     <!-- Broadcast receiver --> 
     <receiver android:name="com.code4reference.enabledisablebroadcastreceiver.AlarmManagerBroadcastReceiver" > 
      <intent-filter> 
       <action android:name="android.intent.action.TIME_TICK" > 
       </action> 
      </intent-filter> 
     </receiver> 
    </application> 

</manifest>

public class EnableDisableBroadcastReceiver extends Activity { 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
    } 

    public void enableBroadcastReceiver(View view){ 
     ComponentName receiver = new ComponentName(this, AlarmManagerBroadcastReceiver.class); 
     PackageManager pm = this.getPackageManager(); 

     pm.setComponentEnabledSetting(receiver, 
       PackageManager.COMPONENT_ENABLED_STATE_ENABLED, 
       PackageManager.DONT_KILL_APP); 
     Toast.makeText(this, "Enabled broadcast receiver", Toast.LENGTH_SHORT).show(); 
    } 

    public void disableBroadcastReceiver(View view){ 
     ComponentName receiver = new ComponentName(this, AlarmManagerBroadcastReceiver.class); 
     PackageManager pm = this.getPackageManager(); 

     pm.setComponentEnabledSetting(receiver, 
       PackageManager.COMPONENT_ENABLED_STATE_DISABLED, 
       PackageManager.DONT_KILL_APP); 
     Toast.makeText(this, "Disabled broadcst receiver", Toast.LENGTH_SHORT).show(); 
    }  

} 

AlarmManagerBroadcastReceiver.java：

package com.code4reference.enabledisablebroadcastreceiver; 
import java.text.Format; 
import java.text.SimpleDateFormat; 
import java.util.Date; 
import android.content.BroadcastReceiver; 
import android.content.Context; 
import android.content.Intent; 
import android.os.PowerManager; 
import android.util.Log; 
import android.widget.Toast; 

public class AlarmManagerBroadcastReceiver extends BroadcastReceiver { 

    final public static String ONE_TIME = "onetime"; 
    @Override 
    public void onReceive(Context context, Intent intent) { 

     //You can do the processing here update the widget/remote views. 
     StringBuilder msgStr = new StringBuilder(); 

     Format formatter = new SimpleDateFormat("hh:mm:ss a"); 
     msgStr.append(formatter.format(new Date())); 

     Toast.makeText(context, msgStr, Toast.LENGTH_SHORT).show(); 

     Log.d("CWCGR1",msgStr.toString()); 
    } 
}

你必须从你的活动叫sendBroadcast：

Intent broadcast = new Intent(); 
broadcast.setAction("android.intent.action.TIME_TICK"); 
sendBroadcast(broadcast); 

你可以把PARAMS到你的意图。
