启用multiDex后仍然出现Unable to merge dex

Question

我找到的所有解决方案都启用了 multiDex 我试过了但没有用另一个解决方案是启用它并添加 compile 'com.android.support:multidex:1.0.2' 但也没有用

Gradle :

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "recipe.bakes.bakesrecipe"
        minSdkVersion 21
        targetSdkVersion 26
        multiDexEnabled true
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    implementation 'com.android.support:support-v4:26.1.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
    compile 'com.android.support:support-fragment:26.1.0'
    compile 'com.android.support:cardview-v7:26.1.0'
    compile 'com.android.support:recyclerview-v7:26.1.0'
    implementation 'com.android.support:appcompat-v7:26.1.0'
    compile 'com.android.volley:volley:1.1.0'
    compile 'com.google.code.gson:gson:2.8.2'
    compile 'com.android.support:multidex:1.0.2'
    implementation files('libs/gson-2.8.2.jar'

)
}

Answer 1

不要为您的项目使用多个相同的依赖项。你只需要使用其中一个 gson.

从 libs 目录和 build.gradle 依赖项中删除 gson jar。你的依赖块应该是这样的：

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    ...
    implementation 'com.google.code.gson:gson:2.8.2'
    //implementation files('libs/gson-2.8.2.jar')
}

对于您当前的依赖项块，您实际上并不需要 multidex。

启用multiDex后仍然出现Unable to merge dex
