java.lang.NoClassDefFoundError: risoluzione non riuscita di: Lcom / mapbox / android / telemetry / MapboxTelemetry;

Question

Sto imparando mapbox e ho implementato mapbox con kotlin seguito dal tutorial di mapbox

ma quando eseguo il codice ottengo la seguente eccezione quando eseguo il dispositivo reale

java.lang.NoClassDefFoundError: Failed resolution of: Lcom/mapbox/android/telemetry/MapboxTelemetry;

Voglio sapere cosa sta causando l'eccezione

quello che ho provato l'ho aggiunto seguendo le regole del programma mapbox

sotto il mio proguard-rules.pro

# 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

sotto build.gradle (: app)

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'
        }
    }
}

    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'

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

Voglio sapere esattamente dove ho commesso l'errore, eventuali suggerimenti, suggerimenti, aiuto molto apprezzato!

Answer 1

Penso che quando aggiungi mapbox come dipendenza locale, alcune dipendenze non sono incluse nel progetto, quindi aggiungi questa riga di codice; che ha risolto il mio problema, ovviamente produce un nuovo errore, ma rimuovi l'errore di telemetria:

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