Android java.lang.NoClassDefFoundError:com.nineodeldroids.view.ViewHelper

我正在使用。我导入了所有依赖项，如Nineolandroid、毕加索和这个'com.daimajia.slider:library:1.1。2@aar'并按照Github上的指导进行编码。但每当我尝试运行应用程序时，它都会停止并显示错误。我的biuld.gradle for app是。非常感谢。已经花了两天了

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:appcompat-v7:22.1.0'
compile 'com.squareup.picasso:picasso:2.3.2'
compile 'com.daimajia.slider:library:1.1.2@aar'
compile 'com.android.support:recyclerview-v7:21.0.+'
compile files('C:/Users/Vinit/Downloads/Coupan/library/volley.jar')
compile files('C:/Users/Vinit/Downloads/Coupan/library/nineoldandroids-2.3.0.jar')}

不知道我在哪里做错了什么。这是我的日志文件

检查libs文件夹是否存在

检查android下的右键单击属性，如果您的lib是外部lib，则正确添加；如果存在，则检查构建路径

---

GL

在android studio中将lib文件夹中的所有库移动到应用程序文件夹下，然后将其路径添加到build.gradle dependencies中

前-

compile files('lib/volley.jar')

---

两天后，我终于找到了解决办法。我刚才补充说：

---

实现'com.nineodandroid:library:2.4.0'

不推荐使用nineodandroid。不会有新的发展。现有版本（当然）将继续发挥作用。新应用程序应使用minSdkVersion=“14”或更高版本，该版本可以访问平台动画API。

我的库中有nineodandroid.jar，外部库文件夹中有picasso和daimajia。我使用的是android studio。好吧，我只知道在eclipse sryuse中是如何处理它的——编译'com.nineodeldroids:library:2.4.0'而不是添加.jar文件。希望这能在你回答之前3分钟起作用。你从sajal那里得到了同样的答案：3你节省了我的时间
