Question

我正在尝试在Android Studio中编译我的项目，我收到以下错误

UNEXPECTED TOP-LEVEL EXCEPTION:
    com.android.dex.DexException: Multiple dex files define Landroid/support/v13/app/FragmentCompat$FragmentCompatImpl;
      at com.android.dx.merge.DexMerger.readSortableTypes(DexMerger.java:594)

      at com.android.dx.command.dexer.Main.main(Main.java:199)
      at com.android.dx.command.Main.main(Main.java:103)

正在运行

$ gradle -q dependencies

产生以下结果

compile - Classpath for compiling the main sources.
+--- project :facebookSDK
+--- project :stripe
+--- project :paymentKitLibrary
+--- com.google.code.gson:gson:2.2.4
+--- com.google.android.gms:play-services:4.3.23
+--- com.android.support:appcompat-v7:+ -> 19.1.0
+--- com.squareup.picasso:picasso:2.2.0
+--- com.loopj.android:android-async-http:1.4.4
\--- com.android.support:support-v13:+ -> 19.1.0
     \--- com.android.support:support-v4:19.1.0

以下是我的gradle依赖项

dependencies {
    compile project(':facebookSDK')
    compile project(':stripe')
    compile project(':paymentKitLibrary')
    compile 'com.google.code.gson:gson:2.2.4'
    compile ('com.google.android.gms:play-services:4.3.23'){
        exclude module: 'support-v4'
    }
    compile ('com.android.support:appcompat-v7:+'){
        exclude module: 'support-v4'
    }
    compile 'com.squareup.picasso:picasso:2.2.0'
    compile 'com.loopj.android:android-async-http:1.4.4'
    compile "com.android.support:support-v13:+"
    compile files('libs/crashlytics.jar')
    compile files('libs/libGoogleAnalyticsV2.jar')
    compile files('libs/MobileAppTracker.jar')
    compile files('libs/twitter4j-core-3.0.5.jar')
}

我不明白冲突的来源。是否有可能来自其中一个jar文件？无论如何，问题是什么？

我认为问题是该类＆＃34; android.support.v13.app.FragmentCompat $ FragmentCompatImpl＆＃34;在依赖项中声明两次。此类包含在以下两个依赖项中：

compile ('com.android.support:appcompat-v7:+'){
    exclude module: 'support-v4'
}

compile "com.android.support:support-v13:+"

＆＃34; support-v13＆＃34;库已包含＆＃34; appcompat-v7＆＃34;库。

尝试删除＆＃34; appcompat-v7＆＃34;您的＆＃34; build.gradle＆＃34;中的库文件，它应该编译。

// *** remove this ****
compile ('com.android.support:appcompat-v7:+'){
    exclude module: 'support-v4'
}

希望这有帮助。

多个dex文件定义了Landroid / support / v13 / app
