在Android应用中使用mapbox在地图上显示用户当前位置时出错

Question

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' } 
}

    implementation 'com.mapbox.mapboxsdk:mapbox-android-navigation:0.23.0'
    implementation 'com.mapbox.mapboxsdk:mapbox-android-plugin-locationlayer:0.11.0'
    implementation 'com.mapbox.mapboxsdk:mapbox-android-sdk:6.7.1'*
