Inner Nested Static Class cannot be called from another class

Question

I have one class in a file named WeatherContract.java which has a static inner class, as follows:

public class WeatherContract {
...
...
    public static final class WeatherEntry implements BaseColumns {
    ...
    ...
    }
}

Now I am trying to call the inner class in another file called TestWeatherContract.java as follows

...
import com.example.android.sunshine.app.data.WeatherContract;
...

public class TestWeatherContract extends AndroidTestCase {
...
    public void testBuildWeatherLocation() {
        Uri locationUri = WeatherContract.WeatherEntry.buildWeatherLocation(TEST_WEATHER_LOCATION);
...

Now in the following line, the word "WeatherEntry" is marked in red and when I hover on the word I get the following error "Cannot resolve symbol 'WeatherEntry'.

Uri locationUri = WeatherContract.WeatherEntry.buildWeatherLocation(TEST_WEATHER_LOCATION);

Please note that I am not getting any error in the import statement, so I'm assuming that there are no errors in stating the path of the class.

Also, I have another file called FetchWeatherTask.java. I have the following import statement at the beginning of the file:

import com.example.android.sunshine.app.data.WeatherContract.WeatherEntry;

In this case, in the import statement again the word "WeatherEntry" is marked in red and I get the error "Cannot resolve symbol 'WeatherEntry'".

Please help. I'm on Android Studio 1.5. I have posted this question earlier, but it was put on hold because I provided incomplete details. So I am posting it again with all details. I'm sorry if I have violated the rules of the community, I am new here. Thank you.

remove final from WeatherEntry and check

WeatherEntry is a class and not a member. To access methods of WeatherEntry you still need an instance of it. E.g.

WeatherContract.WeatherEntry.buildWeatherLocation(TEST_WEATHER_LOCATION);

should be

WeatherEntry weatherEntry = new WeatherContract.WeatherEntry();
weatherEntry.buildWeatherLocation(TEST_WEATHER_LOCATION);
