android - java.lang.NoClassDefFoundError:无法解决以下问题:Lcom/mapbox/android/telemetry/MapboxTelemetry;

Question

我正在学习mapbox，并且已经在kotlin和following mapbox tutorial之后实现了mapbox
但是当我运行代码时，我在运行真实设备时遇到异常

我想知道是什么导致异常
我尝试过的操作我添加了以下mapbox proguard-rules
在我的proguard-rules.pro下面

# Add project specific ProGuard rules here.
# You can control the set of applied configuration files using the
# proguardFiles setting in build.gradle.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
#   public *;
#}

-dontwarn com.mapbox.services.android.location.LostLocationEngine
-dontwarn com.mapbox.services.android.location.MockLocationEngine


# Uncomment this to preserve the line number information for
# debugging stack traces.
#-keepattributes SourceFile,LineNumberTable

# If you keep the line number information, uncomment this to
# hide the original source file name.
#-renamesourcefileattribute SourceFile

在build.gradle(:app)下面

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.2"

    defaultConfig {
        applicationId "com.example.myapplication"
        minSdkVersion 14
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: "libs", include: ["*.jar"])
    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    implementation 'androidx.core:core-ktx:1.1.0'
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation project(':mapbox-android-sdk-9.5.0')

    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}

我想知道我到底在哪里犯了错误，任何提示，建议，帮助都非常有用!

我认为当您将mapbox添加为本地依赖项时，某些依赖项未包含在项目中，因此请添加以下代码行；解决了我的问题，当然会产生新的错误，但要消除遥测错误:

implementation 'com.mapbox.mapboxsdk:mapbox-android-telemetry:6.2.0'
