Xamarin - Classes not found (android support library)

Question

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

Following the tutorial .

But I'm getting the following error

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

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

Answer 1

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

I also installed Google APIs and Sources for Android SDK

Answer 2

I had a similar issue to yours and resolved it by:

1. Downloading the "android_m2repository_r22.zip" at " https://dl-ssl.google.com/android/repository/android_m2repository_r22.zip "
2. Create a folder called "content" in the directory "C:\\Users\\Javaad\\AppData\\Local\\Xamarin\\Xamarin.Android.Support.v4\\23.0.1.3", yours will have a different user name.
3. Then extract the contents of that zip file into the "content" folder.
4. Clean your project
5. Build

Hope this helps.
