main:

    //定义经纬度
    double longitude=104.10;
    double latitude=30.67;

    //定义半径
    float radius=5000;

    //定义Intent
    Intent intent=new Intent(this,ProximityAlertReceiver.class);

    //将Intent包装成PendingIntent
    PendingIntent pi=PendingIntent.getBroadcast(this, -1, intent, 0);

    //添加临近警告
    /**
     * 参数说明
     * 维度
     * 经度
     * 半径
     * 过期时间 -1永不过期

    lm.addProximityAlert(latitude, longitude, radius, -1, pi);
}

广播接受者:

public class ProximityAlertReceiver extends BroadcastReceiver{

@Override
public void onReceive(Context context, Intent intent) {

    //获取是否进入指定区域
    boolean isEnter=intent.getBooleanExtra(LocationManager.KEY_PROXIMITY_ENTERING, false);

    Log.e("isEnter", isEnter+"");

    if(isEnter){

        Toast.makeText(context, "您已经进入到B8", Toast.LENGTH_LONG).show();

    }
    else{

        Toast.makeText(context, "您已经离开奇虎B8", Toast.LENGTH_LONG).show();
    }

}


}

动态权限也加了，但不管在模拟器还是手机当中，都出不来Toast

as 是3.6版本，问题的原因应该与广播发送和接收有关
