我在将Twitter Fabric SDK集成到我的应用程序时遇到了困难.我按照
Twitter tutorial的步骤进行操作,但是当我尝试用gradle构建我的项目时,我得到了这个错误：
- Error:Execution Failed for task ':app:dexDebug'.
- > com.android.ide.common.internal.LoggedErrorException: Failed to run command:
- D:\Android\android-studio\sdk\build-tools\android-4.4W\dx.bat --dex --output ...
- Error Code: 2
- Output:

我尝试从我的app模块lib文件夹中删除我的静态Gson库,之后一切都很顺利.删除从gradle模块依赖项添加twitter sdk的行时也一样,所以我很确定这两者之间存在某种冲突,我正在寻求解决它.
任何帮助将不胜感激 ！
如果它对人们有任何用处,这里有我的gradle app模块文件：
- apply plugin: 'com.android.application'
- apply plugin: 'io.fabric'
- android {
- ...
- buildTypes {
- release {
- runProguard false
- proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro'
- }
- debug {
- signingConfig signingConfigs.debug
- ext.enableCrashlytics = false
- }
- }
- }
- repositories {
- jcenter()
- mavenCentral()
- maven{ url 'https://maven.fabric.io/repo'}
- }
- dependencies {
- compile fileTree(dir: 'libs',include: ['*.jar'])
- compile project(':facebook')
- compile 'com.android.support:support-v13:20.0.0'
- compile 'com.google.android.gms:play-services:6.1.11'
- compile('com.twitter.sdk.android:twitter:1.0.0@aar') {
- transitive = true;
- }
- }
解决方法
我是Twitter Android开发人员.
尝试运行./gradlew app：dependencies以查看gradle任务的所有依赖项.您的编译依赖项将包括以下内容：
- +--- com.twitter.sdk.android:twitter-core:1.0.0
- | | +--- com.squareup.retrofit:retrofit:1.6.1
- | | | \--- com.google.code.gson:gson:2.2.4
- | | +--- com.google.code.gson:gson:2.2.4
- | | \--- io.fabric.sdk.android:fabric:1.0.0
这表明GSON确实被Fabric内部使用.
我的建议是从你的libs /文件夹中删除GSON,并将其作为直接依赖项添加到build.gradle中,而不是将其从Twitter deps图中排除.您也可以利用构建工具中的依赖项解析机制.
- dependencies {
- compile fileTree(dir: 'libs',include: ['*.jar']) // Maybe remove this.
- compile project(':facebook')
- compile 'com.android.support:support-v13:20.0.0'
- compile 'com.google.android.gms:play-services:6.1.11'
- compile('com.twitter.sdk.android:twitter:1.0.0@aar') {
- transitive = true;
- }
- compile 'com.google.code.gson:gson:2.2.4' // Added.
- }
