After spending several hours I found the fixed. Actually I am doing a silly mistake during configuring
the test environment.Just forgot to add the project reference , due to this my test project could not
find the Androidmanifest.xml file.

Go to argument tab under junit test run configuration and select the second radio buttoni.e Other and browse and select you android project.

All done now run your project.

Enjoy coding... :)

Hello Droid Guys,
           This is my first android Hello World test project using Roboelectric.
This tutoial covers  following testing topic.

                                                                                 

1. How to test text on a TextView using Roboelectric in Android.                          
2. How to test image on a ImageView using Roboelectric in Android
3. How to test New Activity call using Roboelectric in Android
4. Testing Button is visible or not in Android using Roboelectric
5. Test case for button click in android using Roboelectric
5. How to check intent using Roboelectric in Android
6. How to make API call using Roboelectric in Android
7. Calling HTTP request in Android Roboelectric test project

Before starting writing the above listed test case , If you are thinking about how to setup
your First android test project , then see the Robolectric Setup  tutorial .

First of all I am going to create an android Project "RoboElectric" .

Here is my Android Code:

1. MainActivity.java :

package com.example.roboelectric;

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;

public class MainActivity extends Activity {

 Button login;
 EditText name;
 EditText password;

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

  login = (Button) findViewById(R.id.login);
  name = (EditText) findViewById(R.id.name);
  password = (EditText) findViewById(R.id.password);

  login.setOnClickListener(new OnClickListener() {

   @Override
   public void onClick(View v) {
    Intent home = new Intent(MainActivity.this, Home.class);
    startActivity(home);
   }
  });

 }

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  // Inflate the menu; this adds items to the action bar if it is present.
  getMenuInflater().inflate(R.menu.activity_main, menu);
  return true;
 }

}

2. Home.java

package com.example.roboelectric;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;

public class Home extends Activity {

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

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  // Inflate the menu; this adds items to the action bar if it is present.
  getMenuInflater().inflate(R.menu.activity_home, menu);
  return true;
 }

}

3. Second.java

package com.example.roboelectric;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;

public class Home extends Activity {

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

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  // Inflate the menu; this adds items to the action bar if it is present.
  getMenuInflater().inflate(R.menu.activity_home, menu);
  return true;
 }

}

4. AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.roboelectric"
    android:versioncode="1"
    android:versionname="1.0" >

  <uses-sdk
        android:minsdkversion="8"
        android:targetsdkversion="16" >

        <application
            android:allowbackup="true"
            android:icon="@drawable/ic_launcher"
            android:label="@string/app_name"
            android:theme="@style/AppTheme" >

            <activity
                android:name="com.example.roboelectric.MainActivity"
                android:label="@string/app_name" >
                <intent-filter>
                  <action android:name="android.intent.action.MAIN" >
                     <category android:name="android.intent.category.LAUNCHER" >
                     </category>
                   </action>
                </intent-filter>
            </activity>
            <activity
                android:name="com.example.roboelectric.Home"
                android:label="@string/title_activity_home" >
            </activity>
          <activity
                android:name="com.example.roboelectric.Second"
                android:label="@string/title_activity_second" >
            </activity>
        </application>
  </uses-sdk>
</manifest>

What Are the expected test case for above android project ?? 

 1. checking hello world text
 2. login button is visible or not
 3. test startActivity() starts a new activity or not on click of login button '
 Now, I am Going to write my test Project "RoboElectricTest"

1.MyActivityTest.java

import java.io.IOException;

import org.robolectric.Robolectric;
import org.robolectric.RobolectricTestRunner;
import org.robolectric.matchers.StartedMatcher;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;

import android.util.Log;
import android.view.View;
import android.widget.Button;

import com.example.roboelectric.Home;
import com.example.roboelectric.MainActivity;
import com.example.roboelectric.R;
import com.example.roboelectric.Second;

import static org.hamcrest.CoreMatchers.equalTo;
import static org.junit.Assert.assertThat;

@RunWith(RobolectricTestRunner.class)
public class MyActivityTest {

 private MainActivity activity;
 private Button login;
 
 @Before
 public void setUp() throws Exception {
   activity = new MainActivity();
   activity.onCreate(null);
   login = (Button) activity.findViewById(R.id.login);
 }
 
  // checking hello world text
 @Test 
 public void shouldHaveHappySmiles() throws Exception {
  String hello = new MainActivity().getResources().getString( R.string.hello_world);
  assertThat(hello, equalTo("Hello world!"));
 }   
 // Button visible 
 @Test 
 public void testButtonsVisible() { 
  assertThat(login.getVisibility(), equalTo(View.VISIBLE)); 
 } 
 
 // startnew activty 
 @Test 
 public void shouldStartNextActivityWhenButtonIsClicked() { 
  login.performClick();
  assertThat(activity, new StartedMatcher(Home.class));
  }
}

Hope this will helps you ,in writing UI test case for your android project using Roboelectric .

Setting working Environment for Android

Hello My Droid Friends,

Set Working environment for Android

To work on android we need to setup working environment. Before setting up android environment we

need to fulfill some basics like

1. JDK must be installed (to install

http://www.oracle.com/technetwork/java/javase/downloads/index.html)

2. Eclipse for java must be installed (http://www.eclipse.org/downloads/)

We are expecting that eclipse is working fine.

1. Download Android SDK

It includes only the core Standard development Kit (SDK) Tools, which will help us in developing Android Applications.

Download Android SDK from http://developer.android.com/sdk/index.html

After downloading .zip or .tgz package (instead of the SDK installer), unpack it to a safe location on your machine.

We will be using it later on in coming steps.

2. Install Android development Tools (ADT)

In Eclipse From Help menu click on Install New Software option

Click on Add button and on Add Site window fill following url to download Android ADT, you can enter any name in Name field, and click on Ok button.

Eclipse will search for the available tools and show their list.

Select all tools and click on Next. It will start checking the things and will show list of tools which will be installed.

Click on Next button and after a license verification it will start downloading and may take some time depending upon the speed of Internet. After successfully installing it will ask to restart eclipse.

Restart it.

3. Adding SDK Location

From Window menu click on Preferences there would be Android option visible (which is also assurance that android ADT is installed :) ). Here we need to tell Eclipse where the Android SDK is located. So click on Android from list, and then browse it to the SDK unzipped directory and click on Ok.

4. Install SDK Latest Version

After that come up on Android SDK and AVD Manager from the Window menu. Select available packages and select the latest version of the SDK, in my case I will select followings, you can select based on your own choice and click on Install Selected to complete the installation, and restart eclipse after it.

During installation It would be looking like this.

5. Set Up Device

As we are almost done, last step is we need to set up device to work, real device can be attached, but we will be using simulator for the scope of our work. From eclipse interface click on this icon from top left side of IDE.

               

                                                                                                   

Select the option Virtual Devices and click on New.

On Android Virtual Device screen fill the followings and click on Create AVD.

It will show the device added in Android SDK and AVD manager screen

Now our setup is complete and we are ready to develop android applications.


Enjoy Coding :)
Cheers...... :)

android.os.NetworkOnMainThreadException in android

Hello Droid Guys,

Yesterday , I found a strange issue, my application is running fine on most of
the android devices. But when I run the same application on Samsung S-3, S2,
Samsung Galaxy Duos it will be crashed and give me the error

"android.os.NetworkOnMainThreadException".

Caused by: android.os.NetworkOnMainThreadException
10-30 15:07:35.341: E/AndroidRuntime(732):  at android.os.StrictMode$AndroidBlockGuardPolicy.onNetwork(StrictMode.java:1117)

In my application basically I am showing a alert dialog with an logout button and on click of logout
button I am calling the service. This functionality is not working on above few device
and crashes every time on clickinng the logout button .

After spending a lot of time on it I came to know that on device api version below 9 we 
can call or write  network call in Main UI Thread but above api version 9 it gives error
android.os.NetworkOnMainThreadException. This is happening my  case.

There are Two way to fix this Issue:
    1.Instead of writing network call in Main UI Thread use Async Task.
    2.Add below code into your activity class inside onCreate() method just  after the 
      setContentView(R.layout.activity_main).
      
     if( Build.VERSION.SDK_INT >= 9){
            StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
            StrictMode.setThreadPolicy(policy); 
     }



Hoping , this will helps you.
Enjoy Coding :)

Android Shake animation

Hello Droid Friends,

This is my another android blog in which I am going to explain the Animation
effect(shake Animation ) in android. When you fill wrong input then instead of
showing the toast messege you can also shake the view.

Steps :
1. Create a project with name "Shake animation" and package name
    "com.mukesh.shakeanimation".
2. add an "anim" folder inside the res folder.see the image below.

 
Source Code:

1. Activity Class:

package com.mukesh.shakeanimation;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.Toast;

public class MainActivity extends Activity implements View.OnClickListener {

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

  View loginButton = findViewById(R.id.login);
  loginButton.setOnClickListener(this);
 }

 public void onClick(View v) {
  Animation shake = AnimationUtils.loadAnimation(this, R.anim.shake);
     findViewById(R.id.pw).startAnimation(shake);
     Toast.makeText(this, "Wrong Password", Toast.LENGTH_SHORT).show();
 }

}

2) activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:background="@drawable/blue_gradient"

    android:orientation="vertical"

    android:padding="10dip" >



    <TextView

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:layout_marginBottom="10dip"

        android:text="Please enter your password:"

        android:textColor="@android:color/white"

        android:textStyle="bold" />



    <EditText

        android:id="@+id/pw"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:clickable="true"

        android:password="true"

        android:singleLine="true" />



    <Button

        android:id="@+id/login"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:background="@drawable/btn_active_pressed"

        android:padding="5dp"

        android:text="Login"

        android:textColor="@android:color/white"

        android:textStyle="bold" />



</LinearLayout>

3. res/anim/shake.xml

<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="500"
    android:fromXDelta="0"
    android:interpolator="@anim/cycle_7"
    android:toXDelta="10" />

4. res/anim/cycle_7.xml

<cycleInterpolator xmlns:android="http://schemas.android.com/apk/res/android"
