Unable to get provider com.nt4f04und.android_content_provider_example.MyAndroidContentProvider

Hello,

I'm trying to add functionality of providing data to example. I'm following instructions in README and I did all steps.

When I'm trying to build it - it stacks and shows me an error.

Looks like it failed to found instance of class MyAndroidContentProvider.

Hi @GlebUstimenkoWMG, I bet what was misleading/not clear from those instructions is that you also need to add a package directive at the top of the file where you defined MyAndroidContentProvider

package com.nt4f04und.android_content_provider_example

I added an example of AndroidContentProvider into example and made the README instructrions more clear in #4 - can you take a look if that's more helpful now?
