Question

我设置了一个广播接收器，但它没有收到我发送的广播消息：

我的清单

<receiver android:name="BootReceiver" >
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
        <action android:name="com.example.manyexampleapp.LocationService.LOCATION_BROAD_MSG" />
    </intent-filter>
</receiver>

发送（调试显示我到达发送线）

public class LocationService extends Service {
public static final String LOCATION_BROAD_MSG = "Hello";
private static final int TWO_MINUTES = 1000 * 60 * 2;

public LocationManager locationManager;
public MyLocationListener listener;
public Location previousBestLocation = null;

Intent intent;
int counter = 0;

@Override
public void onCreate() {
    super.onCreate();
    intent = new Intent(LOCATION_BROAD_MSG);      
}

@Override
public void onStart(Intent intent, int startId) {      

}

    public class MyLocationListener implements LocationListener
    {

        public void onLocationChanged(final Location loc)
        {
       intent = new Intent(LOCATION_BROAD_MSG); 
            Log.i("**************************************", "Location changed");
            if(isBetterLocation(loc, previousBestLocation)) {
                intent.putExtra("Latitude", loc.getLatitude());
                intent.putExtra("Longitude", loc.getLongitude());     
                intent.putExtra("Provider", loc.getProvider());                 
                sendBroadcast(intent);          

            }                               
        }

}

接收（在调试期间从未到达onReceive）

public class BootReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context arg0, Intent intent) {
        // TODO Auto-generated method stub


        if (intent != null)
        {

            String action = intent.getAction();

            if (action != null)
            {
                if (action.equalsIgnoreCase(Intent.ACTION_BOOT_COMPLETED))
                {
                                            //   Log.d("receiver","action is: boot");
                }

                if (action.equalsIgnoreCase(LocationService.LOCATION_BROAD_MSG))
                {
                        //Toast.makeText(, "wee hee", Toast.LENGTH_LONG);
                }

            }
            }
    }

}

Answer 1

更改此行：

public static final String LOCATION_BROAD_MSG = "com.example.manyexampleapp.LocationService.LOCATION_BROAD_MSG";

您已在接收方注册com.example.manyexampleapp.LocationService.LOCATION_BROAD_MSG作为意图过滤器。

Answer 2

问题是您正在注册广播以接收来自以下内容的消息： com.example.manyexampleapp.LocationService.LOCATION_BROAD_MSG而你发送的是： LOCATION_BROAD_MSG = "Hello" ..

你应该

public static final String LOCATION_BROAD_MSG = "com.example.manyexampleapp.LocationService.LOCATION_BROAD_MSG";

广播接收器不响应广播消息
