继续[MonoDroid] Java.Lang.NoClassDefFoundError：抛出了类型'Java.Lang.NoClassDefFoundError'的异常。在发布模式下

Question

如果我在调试模式下运行我的应用程序，一切正常。 如果我在发布模式下构建它，它会运行0错误但是一旦我启动应用程序，我就会在发布模式下出现以下错误

[MonoDroid] Java.Lang.NoClassDefFoundError：抛出了类型'Java.Lang.NoClassDefFoundError'的异常。

我该如何解决这个问题？ 这是我的输出

Answer 1

what are the steps for that? where is AppCompat located?

在此处下载支持库：

http://developer.android.com/tools/support-library/setup.html

如果您使用的是Eclipse：

转到顶部的标签页并选择（Windows - ＆gt; Android SDK Manager）。在“额外”部分下，选中“Android支持库”并检查其是否安装。

之后，可以在以下位置找到AppCompat库：

android-sdk/extras/android/support/v7/appcompat

您需要在Android项目中引用此AppCompat库。

将库导入Eclipse。

右键点击您的Android项目。

选择属性。

点击底部的“添加...”添加图书馆。

选择支持库

清理并重建您的项目。
