AndroidHttpClient not found (when running Robolectric)

I was able to solve this problem by creating a new class called AndroidHttpClient within a new package android.net.http. After that I had to annotate my Unit Test class with @Config(constants = BuildConfig.class, sdks = 21) which will run the tests against an emulated version of API 21 which is the last version of Android Robolectric supports currently.

There is currently an issue opened here, so once they release version 3.1 everything should be fine and you won't have to use this workaround.

I've just added fake class android.net.http.AndroidHttpClient in my test sources. And it solved the issue for now. Waiting for Robolectric to be updated

AndroidHttpClient was removed from the SDK in v23 of the build tools.

As Robolectric is running against earlier versions, it expects it to be there, which is why you're seeing this error.

For now, you can add it back in:

android {
    useLibrary 'org.apache.http.legacy'
}

As detailed here.

There is a GitHub ticket open for Robolectric to fix this. You can follow the thread/ticket here.

Update:

As some people have correctly pointed out, a better way of doing this would be to create a class android.net.http.AndroidHttpClient in your test resources. This would be a preferred method because you're only modifying the test sources, not the production code, in order to accommodate the tests.

Apparent problem and solution:

AndroidHttpClient was removed from the SDK in API Level 23, while Robolectric was set to run tests with SDK 21:
