我试图建立最基本的接近警戒，但似乎没有发生。我是相当新的Android的编程，所以请让我知道我做错了还是我缺少什么。我从一些源$ C $ CS这里拿出来和的这个。这是我的code：
包com.example.proximityalert;
进口android.location.LocationManager;
进口android.os.Bundle;
进口android.app.Activity;
进口android.app.PendingIntent;
进口android.content.Context;
进口android.content.Intent;
进口android.content.IntentFilter;
公共类MainActivity延伸活动{
私有静态最后弦乐PROX_ALERT_INTENT =com.example.proximityalert;
私人IntentReceiver locationReminderReceiver;
@覆盖
保护无效的onCreate（包savedInstanceState）{
super.onCreate（savedInstanceState）;
的setContentView（R.layout.activity_main）;
意向意图=新的意图（PROX_ALERT_INTENT）;
PendingIntent pendingIntent = PendingIntent.getBroadcast（MainActivity.this，0，意向，PendingIntent.FLAG_ONE_SHOT）;
LocationManager locationManager =（LocationManager）this.getSystemService（Context.LOCATION_SERVICE）;
locationManager.addProximityAlert（55.586301,13.045417，200，-1，pendingIntent）;
this.locationReminderReceiver =新IntentReceiver（）;
最后IntentFilter的过滤器=新的IntentFilter（PROX_ALERT_INTENT）;
this.registerReceiver（this.locationReminderReceiver，过滤器）;
}
}
和接收器
包com.example.proximityalert;
进口android.content.BroadcastReceiver;
进口android.content.Context;
进口android.content.Intent;
进口android.location.LocationManager;
进口android.util.Log;
进口android.widget.Toast;
公共类IntentReceiver扩展的BroadcastReceiver {
// @燮pressWarnings（德precation）
@覆盖
公共无效的onReceive（上下文的背景下，意图意图）{
字符串键= LocationManager.KEY_PROXIMITY_ENTERING;
布尔进入= intent.getBooleanExtra（键，FALSE）;
如果（进入）{
Toast.makeText（上下文中，LocationReminderReceiver输入，Toast.LENGTH_SHORT）.show（）;
Log.i（LocationReminderReceiver，输入）;
} 其他 {
Toast.makeText（上下文中，LocationReminderReceiver退出，Toast.LENGTH_SHORT）.show（）;
Log.i（LocationReminderReceiver，退出）;
}
}
}

您必须更换数据库查询和一些code，以满足您的应用程序，这是一个多接近警报这就是为什么有n的增量。
I'm trying to set up the most basic proximity alert, but nothing seems to happen. I'm fairly new to Android programming, so please let me know what I'm doing wrong or what am I missing. I got inspired from some source codes out here and this one. Here's my code:
package com.example.proximityalert;
import android.location.LocationManager;
import android.os.Bundle;
import android.app.Activity;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
public class MainActivity extends Activity {
private static final String PROX_ALERT_INTENT = "com.example.proximityalert";
private IntentReceiver locationReminderReceiver;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent intent = new Intent(PROX_ALERT_INTENT);
PendingIntent pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
locationManager.addProximityAlert(55.586301,13.045417, 200, -1, pendingIntent);
this.locationReminderReceiver = new IntentReceiver();
final IntentFilter filter = new IntentFilter(PROX_ALERT_INTENT);
this.registerReceiver(this.locationReminderReceiver, filter);
}
}
and the Receiver
package com.example.proximityalert;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.location.LocationManager;
import android.util.Log;
import android.widget.Toast;
public class IntentReceiver extends BroadcastReceiver{
// @SuppressWarnings("deprecation")
@Override
public void onReceive(Context context, Intent intent) {
String key = LocationManager.KEY_PROXIMITY_ENTERING;
Boolean entering = intent.getBooleanExtra(key, false);
if (entering) {
Toast.makeText(context, "LocationReminderReceiver entering", Toast.LENGTH_SHORT).show();
Log.i("LocationReminderReceiver", "entering");
} else {
Toast.makeText(context, "LocationReminderReceiver exiting", Toast.LENGTH_SHORT).show();
Log.i("LocationReminderReceiver", "exiting");
}
}
}

This is the service that i use to get proximity alerts, your welcome to use it, it doesnt need the reciever in the manifest, just the service

}
public void onProviderEnabled(String s) {
}
@Override

}
}
}
you would have to replace the database query and some of the code to fit your app, this is for multiple proximity alerts thats why there is the increment of n.
