【问题描述】:
我是一名 android 初学者,正在 Android 上测试一些 Estimote-Beacons。我的项目使用 Estimote 库,但现在我想尝试更开放的 altbeacon-library,但我遇到了几个问题。
我的应用程序的功能应该是这样的: 当应用程序启动时,BeaconApplication 应该启动 BeaconsMonitoringService。应监测两个区域。如果输入了一个区域,服务应该使用广播管理器发送一个意图。使用意图信息,应在主活动中选中/取消选中复选框。 当应用被杀死或蓝牙状态发生变化时,该服务也会启动。
问题是:
- 未检测到区域
- 未设置扫描周期
显示所有调试日志,除了来自 onBeaconServiceConnect 的“Entered”和“Left”。 任何帮助,将不胜感激。希望这只是一个愚蠢的/新手错误,并且通常可以正常工作。 :)
这是我的 BeaconApplication 代码:
package de.mcd.presencealtbeacon;
import android.app.Application;
import android.content.Intent;
import org.altbeacon.beacon.BeaconManager;
public class BeaconApplication extends Application {
private BeaconManager beaconManager = null;
@Override
public void onCreate() {
super.onCreate();
beaconManager = BeaconManager.getInstanceForApplication(this);
startService(new Intent(getApplicationContext(), BeaconsMonitoringService.class));
}
public BeaconManager getBeaconManager() {
if (beaconManager == null) {
beaconManager = BeaconManager.getInstanceForApplication(this);
}
return beaconManager;
}
}
BeaconsMonitoringService 的代码如下:
