Android Studio Gradle 构建问题(无法运行项目)

Question

我刚刚将我的 Android Studio 更新到最新版本 2.2.2。之后需要更新 gradle。但是在更新两者之后我无法运行我之前运行良好的项目。

下面是 gradle 日志错误:-

Answer 1

在您的情况下，解决方案应该是将以下行添加到依赖项:

androidTestCompile 'com.android.support:recyclerview-v7:25.0.0'
androidTestCompile 'com.android.support:support-v4:25.0.0'

您还应该调整支持库版本。 在您的情况下，所有这些都应该是 25.0.0

这是类似的问题:Resolved versions for app (22.0.0) and test app (21.0.3) differ

更新: 为了使依赖控制更容易，您可以定义变量，您可以在其中存储当前支持库版本。

因此，您的依赖 block 应该如下所示:

def support_version = '25.0.0'

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile files('libs/YouTubeAndroidPlayerApi.jar')

    // support libraries that should have the same version
    compile "com.android.support:appcompat-v7:$support_version"
    compile "com.android.support:cardview-v7:$support_version"
    compile "com.android.support:support-v4:$support_version"
    compile "com.android.support:recyclerview-v7:$support_version"
    compile "com.android.support:support-annotations:$support_version"
    compile "com.android.support:design:$support_version"

    compile project(':library')
    compile project(':rate-me')
    compile project(':volleyNew')

    compile 'com.facebook.rebound:rebound:0.3.7'
    compile 'com.google.code.gson:gson:2.3.1'
    compile 'com.github.castorflex.smoothprogressbar:library-circular:1.0.2'
    compile 'com.facebook.android:facebook-android-sdk:4.+'
    compile 'com.facebook.android:notifications:1.0.2'
    compile 'com.google.android.gms:play-services:9.6.1'
    compile 'de.keyboardsurfer.android.widget:crouton:1.8.5@aar'
    compile 'com.loopj.android:android-async-http:1.4.6'
    compile 'de.greenrobot:eventbus:2.4.0'
    compile 'org.igniterealtime.smack:smack-android-extensions:4.1.0'
    compile 'org.igniterealtime.smack:smack-experimental:4.1.0'
    compile 'org.igniterealtime.smack:smack-tcp:4.1.0'
    compile 'org.igniterealtime.smack:smack-im:4.1.0'
    compile 'com.loopj.android:android-async-http:1.4.6'
    compile 'com.android.support:multidex:1.0.0'
    compile 'com.squareup.picasso:picasso:2.4.0'

    compile('com.crashlytics.sdk.android:crashlytics:2.6.2@aar') {
        transitive = true;
    }
    compile('com.paypal.sdk:paypal-android-sdk:2.15.0') {
        exclude group: 'io.card'
    }

    androidTestCompile "com.android.support:recyclerview-v7:$support_version"
    androidTestCompile "com.android.support:support-v4:$support_version"
    androidTestCompile "com.android.support:support-annotations:$support_version"

    androidTestCompile 'com.android.support.test:runner:0.2'
    androidTestCompile 'com.android.support.test:rules:0.2'
    androidTestCompile 'com.android.support.test.espresso:espresso-core:2.1'
    androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.0'
}
