4,320 PointsIf you didn't go to one of your folders, probably UI.
Create a new class and paste the following code:
public class AlertDialogFragment extends DialogFragment {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Context context = getActivity();
AlertDialog.Builder builder = new AlertDialog.Builder(context)
.setTitle(context.getString(R.string.error_title))
.setMessage(context.getString(R.string.error_message))
.setPositiveButton(context.getString(R.string.error_ok_botton_text), null);
AlertDialog dialog = builder.create();
return dialog;
}
}

4,320 PointsOh the answer is pretty clear
You have AlertDialogFragment dialog = new AlertdialogFragment():
Capitalize the lowercase D in the new AlertDialogFragment();
50% of bugs are misspelling or lack of capitalization, They are super annoying, but they are super easy to fix.
Good luck!

1,205 PointsThe problem remains.... Its still showing the same error
Dhruv Gupta
4,320 PointsYou did create an AlertDialogFragment class right?
You can't import it if it doesn't exist.

package com.andrecolares.stormy;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import com.squareup.okhttp.Call;
import com.squareup.okhttp.Callback;
import com.squareup.okhttp.OkHttpClient;
import com.squareup.okhttp.Request;
import com.squareup.okhttp.Response;
import java.io.IOException;
public class MainActivity extends AppCompatActivity {
public static final String TAG = MainActivity.class.getSimpleName();
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String apiKey = "b58df3c3139b75263e389c950140c157";
double latitude = 37.8267;
double longitude = -122.423;
String forecastUrl = "https://api.forecast.io/forecast/" + apiKey + "/" + latitude +"," + longitude;
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url(forecastUrl)
.build();
Call call = client.newCall(request);
call.enqueue(new Callback() {
@Override
public void onFailure(Request request, IOException e) {
}
@Override
public void onResponse(Response response) throws IOException {
try {
Log.v(TAG, response.body().string());
if(response.isSuccessful()){
}
else {
alertUserAboutError();
}
} catch (IOException e) {
Log.e(TAG, "Exception caught: ", e);
}
}
});
Log.d(TAG, "Main UI code is running!");
}
private void alertUserAboutError() {
AlertDialogFragment dialog = new AlertDialogFragment();
dialog.show(getFragmentManager(), "error_dialog");
}
}
Don't forget to rename your package.
