Android 使用Radius Networks Pro iBeacon SDK的后台BLE触发器

我正在使用运行Android 4.3的三星Galaxy Tab 2上的Radius Networks iBeacon SDK的专业版进行开发。该应用程序已经成功使用非专业版本0.7一个月了，但我想要背景事件，所以我选择了专业版本1.0。AndroidProximityLibrary项目是Eclipse中的一个项目依赖项，

ProximityKit.properties

文件位于

src/

中

下面的代码是我的应用程序子类，如中所述。该应用程序具有蓝牙和蓝牙管理权限。请注意，从LogCat输出中可以看出，

didDeterminateStateForRegion（）

方法在按预期进入睡眠状态后不会被调用。为了在后台发生一些事情，需要做什么改变

我看到过一个类似的问题，但问题似乎是调用了

IBeaconManager.unbind（）

，这导致操作系统清理了服务。我的代码从不调用

IBeaconManager.unbind（）

，只调用

IBeaconManager.bind（）

我在信标范围外运行应用程序，然后进入范围。30秒后什么也没发生，所以我按下了电源按钮，仍然什么也没发生。我插上电话，从ADB那里得到了线索

在睡眠（家庭，然后通电）和30秒后醒来（通电）之间，LogCat处于信息级别

---

使用

RegionBootstrap

时，不需要调用

iBeacon.bind（this）

也不需要实现

onibeacerviceconnect（）

。这是因为这些任务由

RegionBootstrap

类在内部处理

---

要解决此问题，请尝试手动调用

iBeacon.bind（this）

解决方案是在调用了

setBackgroundBetweenScanPeriod（）

或

setBackgroundScanPeriod（）

之后调用。由于我的代码没有这样做，Radius SDK仍然以默认的间隔（10分钟在后台）扫描。

我删除了

iBeacon.bind（this）

，开始偶尔看到回调发生。但是，当我删除onIBeaconServiceConnect（）时，一切都停止了，直到我读取它。是什么条件导致从“后台”状态调用

dideterministateforregion（）

和

didEnterRegion（）

？在我的测试中，我的成功率只有10%左右。只有当信标消失或从视图中重新出现时，才会调用这些方法。这就是您所期望的吗？我注意到您在OnibeAccerviceConnect（）中有开始范围设置的代码，但我没有看到您在任何地方设置范围通知程序。是否存在未显示的执行此操作的代码？您是否希望使用测距功能而不是RegionBootstrap提供的监控功能？是的，我总是在信标范围外运行应用程序，或者在信标关闭的情况下运行应用程序，然后进入范围或打开信标。这是所有相关的代码-我之所以实现了

ibeaconsumer

，是因为没有它，

didEnterRegion（）

和

didExitRegion（）

没有记录任何内容。我应该澄清，目前，为了让这些东西正常工作，我没有使用任何测距。一旦事情看起来不错，然后是的，我需要合并到一个现有的应用程序，这确实需要范围。

public class ExampleApp extends Application implements BootstrapNotifier, IBeaconConsumer {

    private static final String LOG_TAG = ExampleApp.class.getName();
    private RegionBootstrap regionBootstrap;
    private IBeaconManager iBeacon;
    private Region region;

    public ExampleApp() {
        String uuid = "EBEFD083-70A2-47C8-9837-E7B5634DF520";
        region = new Region("com.example.ble", uuid, null, null);
    }

    @Override
    public void onCreate() {
        super.onCreate();
        iBeacon = IBeaconManager.getInstanceForApplication(this);
        iBeacon.setBackgroundBetweenScanPeriod(10000);
        iBeacon.setBackgroundScanPeriod(3000);
        iBeacon.bind(this);
        regionBootstrap = new RegionBootstrap(this, region);
    }

    @Override
    public void onIBeaconServiceConnect() {
        Log.d(LOG_TAG + ".onIBeaconServiceConnect", "connected to iBeacon service");
        try {
            iBeacon.startRangingBeaconsInRegion(region);
        } catch (RemoteException e) {
            String msg = "caught exception while enabling beacon ranging";
            Log.e(LOG_TAG + ".onIBeaconServiceConnect", msg, e);
        }
    }

    @Override
    public void didEnterRegion(Region region) {
        Log.d(LOG_TAG + ".didEnterRegion", "YEAH ENTERED");
    }

    @Override
    public void didDetermineStateForRegion(int state, Region region) {
        Log.d(LOG_TAG + ".didDetermineStateForRegion", "YEAH STATE");
        Intent intent = new Intent(this, LaunchActivity.class);
        startActivity(intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK));
    }

    @Override
    public void didExitRegion(Region region) {
        Log.d(LOG_TAG + ".didExitRegion", "YEAH EXITED");
    }

}
