我正在android应用中使用mapbox。首次正确运行，但随后的attemtps崩溃
我遇到的错误-
11-30 10:04:41.161 2842-2842/? E/ActivityThread: Activity com.android.launcher2.Launcher has leaked IntentReceiver com.android.launcher2.Launcher$2@2227827 that was originally registered here. Are you missing a call to unregisterReceiver()?
相应的权限，依赖项和代码
我在清单中添加了位置权限。
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
在build.gradle中，我使用了maven {}，在依赖项中，我使用了导航，位置层和mapbox库
repositories {
mavenCentral()
jcenter()
maven { url 'https://mapbox.bintray.com/mapbox' }
