关闭GPS时，广播接收机被叫2次？

Question

表现：

<receiver android:name=".GpsLocationReceiver">
    <intent-filter>
        <action android:name="android.location.PROVIDERS_CHANGED" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</receiver>

BroadcastReceiver：

public class GpsLocationReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d(TAG, "onReceive...");
        if(intent.getAction().matches("android.location.PROVIDERS_CHANGED")) {
            Log.d(TAG, "GPS provider changed...");
            EventBus.getDefault().postLocal(intent.getAction());
        }
    }

}:

为什么不检查您的接收器中是否启用了 GPS 提供商？

lm = (LocationManager) context.getSystemService(LOCATION_SERVICE);
isGPSEnabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
