android - Android 中的运行时异常 java.lang.NoClassDefFoundError : retrofit2. 平台

Question

我正在使用 Rtofit 来处理来自移动设备的服务器端数据在实现改造后我得到以下异常任何知道这个问题的人告诉我我哪里做错了

初始化改造:

mRetrofit = new Retrofit.Builder()
                    .baseUrl(AppConstance.APP_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();
            Iservice = mRetrofit.create(IdeaService.class);

Gradle 文件

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.2.1'
    compile 'com.squareup.retrofit2:retrofit:2.0.2'
    compile 'com.squareup.retrofit2:converter-gson:2.0.0'
    compile 'com.squareup.okhttp:okhttp:2.2.0'
    compile 'com.squareup.okhttp:okhttp-urlconnection:2.0.0'
    compile 'com.squareup.okio:okio:1.7.0'
}

Answer 1

我遇到了同样的问题。可能的解决方案(解决了我的问题):

1) 添加gradle依赖: 编译 'com.android.support:multidex:1.0.0'(文件 build.gradle)

2) 设置multiDexEnabled true (文件build.gradle)

3) 添加android:name="android.support.multidex.MultiDexApplication" (文件AndroidManifest.xml)

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme"
    android:name="android.support.multidex.MultiDexApplication">
 </application>
