我用的是参考,http://altbeacon.github.io/android-beacon-library/samples.html。我还使用了How to detect Region Enter/Exit for multiple beacons using AltBeacon android-beacon-library?
我正在尝试使用AltBeacon的Android Beacon库在后台检测iBeacons。我从我的项目中包含了以下代码片段。到目前为止,我还没有在后台检测到ibeacons……任何帮助都是值得感谢的。
我用beaconmanager
setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24"));
但是,我没有得到错误和信标检测。在三星galaxy 4设备上运行app-in-debug时,app会启动,但不会检测到活动的信标。我的信标是rad信标,配置为ibeacons。rad beacon应用程序会检测到它们,我在前台运行的另一个altbeacon库应用程序也会检测到我的ibeacons。这些应用程序运行在三星Galaxy 4上。
我为后台信标检测设置的应用程序…不检测iBeacons。
这是我的密码。JavaSt.java只是我的应用程序的常量文件。

我没有发现任何伊贝肯病毒。没有发布预期的logcat列表。我是不是漏了一步?
最佳答案
编辑project.properties文件并添加行:
manifestmerger.enabled=true
请参阅此处的完整说明:
http://altbeacon.github.io/android-beacon-library/configure.html
这个问题与你试图识别的信标类型无关。如果没有启用清单合并,androidmanifest.xml文件没有从库继承的服务定义来启动Beaconservice,因此永远不会检测到任何类型的信标。
使用eclipse,您可以通过执行构建来判断清单合并是否正常工作,然后在bin/androidmanifest.xml中查看生成的清单。此清单应包括以下条目。
如果所有其他操作都失败,则可以手动将这些条目复制到项目清单中:
<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
<!-- nest the entries below underneath your application tag -->
<service android:enabled="true" android:exported="true" android:isolatedProcess="false" android:label="beacon" android:name="org.altbeacon.beacon.service.BeaconService">
</service>
<service android:enabled="true" android:name="org.altbeacon.beacon.BeaconIntentProcessor">
</service>
<receiver android:name="org.altbeacon.beacon.startup.StartupBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
<action android:name="android.intent.action.ACTION_POWER_CONNECTED"/>
