我创建了一个侦听Firebase位置的服务。
这是一项内存使用率低的简单服务。不幸的是，我看到一个名为MeasurementBrokerService的Google Play服务加入了我的服务而没有释放内存。
与相关问题不同： "Service MeasurementBrokerService is in use" is showing in my application process
上述问题没有被接受的答案，所以请不要将此标记为重复
我没有使用firebase-appindexing。

有人可以指导我如何阻止服务加入我的流程。
服务如下：

sessionPref = getSharedPreferences("SessionPref",0);

我检查过谷歌AppMeasurement服务仍然在我的设备上运行。
我采用了以下方法：
以下内容阻止了firebase的数据收集。
https://firebase.google.com/support/guides/disable-analytics告诉我们以下方法
<meta-data android:name="firebase_analytics_collection_deactivated" android:value="true" />
仅此一项仍无法阻止appMeasurement初始化。
已解决的第二步是将以下内容添加到应用程序级别gradle文件中：
configurations {
all*.exclude group: 'com.google.firebase', module: 'firebase-core'
}
这基本上删除了firebase分析使用的所有代码。
如果它仍然不起作用，请确保gradle不包含广泛的播放服务依赖性
例如：compile＆＃39; com.google.android.gms：play-services-location：10.0.1＆＃39;
而不是com.google.android.gms：play-services：10.0.1＆＃39;
最糟糕的情况，我没有对此进行测试，因为以上解决了它是：
https://developers.google.com/analytics/devguides/collection/android/v4/advanced
如果没有开发人员的许可，谷歌应该停止放置不需要的东西。希望这有助于某人
