Create xml for main view from layout folder
mainview.xml 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:orientation="vertical" >

        <Button
            android:id="@+id/button1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:onClick="onClickFragment"
            android:text="Button1" />

        <Button
            android:id="@+id/button2"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"

            android:layout_height="wrap_content"
            android:onClick="onClickFragment"
            android:text="Button3" />
    </LinearLayout>

    <LinearLayout
        android:id="@+id/frg_container"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="3"
        android:orientation="vertical" >
    </LinearLayout>

Create xml from layout folder for fragments

fragment1.xml  
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Fragment 1"
        android:textAppearance="?android:attr/textAppearanceLarge" />

</LinearLayout>

fragment2.xml 
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Fragment 2"
        android:textAppearance="?android:attr/textAppearanceLarge" />

</LinearLayout>
 
fragment3.xml  

 <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

        android:layout_height="wrap_content"
        android:text="Fragment 3"

Coding Part

Create MainActivity class from your Package name. 
 
This is the parent Activity which extends FragmentActivity

public class MainActivity extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        FragmentTransaction frgTrans = getSupportFragmentManager()
                .beginTransaction();
        FirstFragment firstFragment = new FirstFragment();
        frgTrans.add(R.id.frg_container, firstFragment);
        frgTrans.commit();
    }

    public void onClickFragment(View view) {

        Fragment newFragment;
        if (view == findViewById(R.id.button1)) {
            newFragment = new FirstFragment();

        } else if (view == findViewById(R.id.button2)) {
            newFragment = new SecondFragment();
        } else if (view == findViewById(R.id.button3)) {
            newFragment = new ThirdFragment();
        } else {
            newFragment = new FirstFragment();
        }
        FragmentTransaction newfrgTrans = getSupportFragmentManager()
                .beginTransaction();
        //newfrgTrans.setCustomAnimations(R.anim.pop_enter,R.anim.pop_exit); //you can also set animations
        newfrgTrans.replace(R.id.frg_container, newFragment);
        newfrgTrans.addToBackStack(null);
        newfrgTrans.commit();
    }


Create FirstFragment class:

public class FirstFragment extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // TODO Auto-generated method stub

        return inflater.inflate(R.layout.fragment1, container, false);
    }

}

Create SecondFragment class:  


public class SecondFragment extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        return inflater.inflate(R.layout.fragment2, container, false);
    }

}

Create ThirdFragment class: 


public class ThirdFragment extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        return inflater.inflate(R.layout.fragment3, container, false);
    }

}

Changing the install location of Android Application

Hi all, Today we are going to learn how to change/modify the install location of Android Application without rooting your Android-device

Some of the Android Devices has no enough space(internal memory) to install the application from google play, so here we have tricky solution for that

Steps to Follow :

1.Download Android SDK 

2.Open Command prompt in ur windows(win+r,type cmd)

3.Type th path of platform-tools where SDK is installed (eg, C:\Users\Anu\android-sdks\platform-tools)

4.Enable the USB Debbuging (Goto Settings-Developer options-USB debugging) in your Device before connecting to the system

5.Now in windows type adb devices, you will get list of devices attached to your system

6.After getting list of devices, type adb shell and you will get $ symbol(Non Rooted)  or # symbol(Rooted) which is ready to execute your command

7.Type set pm setInstallLocation 2 or pm-set-Install-Location 2 

8.Exit & unplug your device and Enjoy by installing your apps to your external memory.

Identifying Outgoing call Phone Number Through our Application

How To Identify Outgoing call Phone Number Through our Application 

1. Use BroadcastReceiver.
2. Add Permission to Your Manifest File.

1.Add the following code 

public class OutgoingCallReceiver extends BroadcastReceiver {

   @Override

   public void onReceive(Context context, Intent intent) {

           Bundle bundle = intent.getExtras();

           if(null == bundle)

                   return;

           String phonenumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);

           Log.i("GetPhoneNumber",phonenumber);

          

           String outgoingNumber =  phonenumber;

           Toast.makeText(context, outgoingNumber , Toast.LENGTH_LONG).show();

   }

}

2.In your Manifest

<receiver android:name=".OutgoingCallReceiver" >

            <intent-filter>

                <action android:name="android.intent.action.NEW_OUTGOING_CALL" />

            </intent-filter>

        </receiver>
