为什么我没有拿到接近alterts即使我已经注册警报？ [英] Why don't I get proximity alterts even though I've registered alerts?
问题描述
我想简单地设置一个接近后一个区域的测试，我只是添加到了我的主要活动的onCreate 方法。
I'm trying to simply set a proximity later for an area an for testing, I simply added this to the onCreate method of my main activity.
public void onCreate(Bundle bndBundle) {
IntentFilter filter = new IntentFilter(WidgetService.ACTION_STOP_PROXIMITY);
registerReceiver(new ProximityIntentReceiver(), filter);
LocationManager locManager = (LocationManager) this.getSystemService(LOCATION_SERVICE);
Intent ittIntent = new Intent(this, ProximityIntentReceiver.class);
ittIntent.putExtra(WidgetService.KEY_STOP_IDENTIFIER, 1000);
PendingIntent pitIntent = PendingIntent.getBroadcast(this, 0, ittIntent, 0);
locManager.addProximityAlert(60.15769, 24.94150, 150, -1, pitIntent);
super.onCreate(bndBundle);
getActionBar().setDisplayHomeAsUpEnabled(false);
}
..这里是我使用简单的接收器类
..and here's the simple receiver class that I'm using
public class ProximityIntentReceiver extends BroadcastReceiver {
private static final int NOTIFICATION_ID = 1000;
@Override
public void onReceive(Context context, Intent intent) {
String key = LocationManager.KEY_PROXIMITY_ENTERING;
Boolean entering = intent.getBooleanExtra(key, false);
if (entering) {
Log.d(getClass().getSimpleName(), "entering");
}
else {
Log.d(getClass().getSimpleName(), "exiting");
}
}
}
我对我的模拟器测试这一点，当我使用DDMS控制台手动设置手机的坐标，我还没有看到日志消息。
I'm testing this on my emulator and when I use the DDMS console to set the co-ordinates of the phone manually, I still don't see the log message.
我的清单文件没有任何特殊的code。我已经添加了正确的权限，并有code一个简单的活动 - 没有服务或任何东西。
My manifest file doesn't have any special code. I've added the correct permissions and have the code for a simple activity- no services or anything.
我经历了一大堆在计算器上的职位读，但我一直没能解决这个问题。我缺少的东西在我的代码片段？
I read through a whole bunch of posts on StacKOverflow but I haven't been able to resolve the issue. Am I missing something in my snippet?
推荐答案
您的动态注册这个接收器，通过 registerReceiver（），有它的广播的行动作出回应字符串 WidgetService.ACTION_STOP_PROXIMITY 。
You are registering this receiver dynamically, through registerReceiver(), to have it respond to broadcasts whose action string is WidgetService.ACTION_STOP_PROXIMITY.
不过，您发送的实际广播试图用一个明确的意图，确定您的接收器类。这不排队的IntentFilter 您使用的是与 registerReceiver（）。
However, the actual broadcast you are sending is trying to use an explicit Intent, identifying your receiver class. This does not line up with the IntentFilter that you are using with registerReceiver().
或者：
-
填写您的接收器清单，摆脱
registerReceiver的（），在这种情况下，您明确意图将工作或
Register your receiver in the manifest and get rid of
registerReceiver(), in which case your explicitIntentwill work, or
使用新意图（WidgetService.ACTION_STOP_PROXIMITY）而不是新意图（这一点，ProximityIntentReceiver.class），所以你的意图与排队的的IntentFilter
Use new Intent(WidgetService.ACTION_STOP_PROXIMITY) instead of new Intent(this, ProximityIntentReceiver.class), so your Intent lines up with your IntentFilter
您不能使用明确的意图对象发送广播通过 registerReceiver注册接收机（）。一个明确的意图将只与清单登记的接收工作。
You cannot use explicit Intent objects to send broadcasts to receivers registered via registerReceiver(). An explicit Intent will only work with a manifest-registered receiver.
