Xamarin-未找到类(Android支持库)

问题描述：

我正在尝试使用AppCompat向后兼容实现Material Design.

I'm trying to implement Material Design with backward compatibility using AppCompat.

但是我遇到了以下错误

Error 1 error: package android.support.v4.app.FragmentManager does not exist android.support.v4.app.FragmentManager.OnBackStackChangedListener C:\Users\Italo\Documents\Xamarin\TemaMaterial\TemaMaterial\obj\Debug\android\src\mono\android\support\v4\app\FragmentManager_OnBackStackChangedListenerImplementor.java 8 41 TemaMaterial Error 2 error: package android.support.v4.content.Loader does not exist android.support.v4.content.Loader.OnLoadCompleteListener C:\Users\Italo\Documents\Xamarin\TemaMaterial\TemaMaterial\obj\Debug\android\src\mono\android\support\v4\content\Loader_OnLoadCompleteListenerImplementor.java 8 36 TemaMaterial Error 3 error: package android.support.v4.content does not exist public void onLoadComplete (android.support.v4.content.Loader p0, java.lang.Object p1) C:\Users\Italo\Documents\Xamarin\TemaMaterial\TemaMaterial\obj\Debug\android\src\mono\android\support\v4\content\Loader_OnLoadCompleteListenerImplementor.java 27 56 TemaMaterial

表示该软件包不存在，但存在. 我仍然无法添加图片，因此，这是链接

It says that the package does not existe, but it exists. I still can't add images, so, here is the link

答

显然，由于zip文件android_m2repository_r14已损坏，因此出现了问题.因此必须手动下载并在%localappdata%\Xamarin\Android.Support.v4和%localappdata%\Xamarin\Android.Support.v7.AppCompat文件夹中解压缩

Apparently the problem occur because the zip file android_m2repository_r14 is corrupted. So is necessary download manually and unzip at %localappdata%\Xamarin\Android.Support.v4 and %localappdata%\Xamarin\Android.Support.v7.AppCompat folders

我还安装了适用于Android SDK的Google API和源代码

I also installed Google APIs and Sources for Android SDK
