My manifest file is

manifest.java 
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.niyamat.stoormyy" >
    <uses-permission android:name="ANDROID.PERMISSION.INTERNET"/>
    <uses-permission android:name="ANDROID.PERMISSION.ACCESS_NETWORK_STATE"/>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:screenOrientation="portrait">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

And my main Activity is

MainActivity.java 
package com.example.niyamat.stoormyy;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;

import com.squareup.okhttp.Call;

import java.io.IOException;

public class MainActivity extends AppCompatActivity {
    private static final String TAG = MainActivity.class.getSimpleName();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        double latitude = 37.8267;
        double longitude = -122.423;
        String apiKey = "4782d6d6e5aee3f63ad0f4191c2e9f15";
        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 {
                    String jsonData = response.body().string();
                    Log.v(TAG, jsonData);
                } catch (Exception e) {
                    Log.e(TAG, "Exception caught", e);
                }
            }
        });

    }

If memory serves, I think the permissions are:

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Notice the difference in case. Try that and see if it helps. Post back if you are still stuck.

Happy coding,
Ken

Hi Ken Alger

Thank you Its work.

But one thing I don't understand that when first time I set the permission the android studio auto completed

<uses-permission android:name="ANDROID.PERMISSION.INTERNET"/>

that line but second time when I set the permission the android studio auto completed

<uses-permission android:name="android.permission.INTERNET" />

that line.So I don't understand why that happen.
