NoClassDefFoundError on RoboSpice

Question

最近，我将我的Android项目从Eclipse迁移到了Android，这有点棘手，该项目使用RoboSpice (1.4.6)并在Android 22上运行，但是当我试图在一个真正的设备(Android 14)上运行它时，它会抛出一个NoClassDefFoundError异常。这是我的堆栈：

我想我需要一个额外的jar依赖--我在网上搜索了很多，但是，希望你能帮我。

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.2.3'
    }
}

模块gradle:我尝试过只使用jars (编译文件树和逐个编译)和通过Maven repo。

您在jars的注释部分中使用了robospice-1.4.6.jar，并且这个版本可能没有包含您要获得错误的类。由于第一个依赖项行compile fileTree(dir: 'libs', include: ['*.jar'])，libs目录中的每个jar文件都将包含在类路径中。

我建议考虑只使用Maven的依赖关系管理，从RoboSpice dir中删除所有与libs相关的jars，并且只包括您实际使用的RoboSpice扩展(对于您的情况，这似乎是'com.octo.android.robospice:robospice-spring-android:1.4.14' )。
