Count How many times your application has run on device

Count howmany time your application has opened on device using shared preference.
put following code in your Main activity.




        // Get the app's shared preferences
        SharedPreferences app_preferences = 
        PreferenceManager.getDefaultSharedPreferences(this);
        
        // Get the value for the run counter
        int counter = app_preferences.getInt("counter", 0);
        
        // Update the TextView
        TextView text = (TextView) findViewById(R.id.text);
        text.setText("This app has been started " + counter + " times.");
        
        // Increment the counter
        SharedPreferences.Editor editor = app_preferences.edit();
        editor.putInt("counter", ++counter);
        editor.commit(); // Very important


YOUR CODE WILL LOOK LIKE FOLLOWING,



package com.AppOpenedCount;


import android.app.Activity;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.preference.PreferenceManager;
import android.widget.TextView;


public class CountAppOpenedActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        
        // Get the app's shared preferences
        SharedPreferences app_preferences = 
        PreferenceManager.getDefaultSharedPreferences(this);
        
        // Get the value for the run counter
        int counter = app_preferences.getInt("counter", 0);
        
        // Update the TextView
        TextView text = (TextView) findViewById(R.id.text);
        text.setText("This app has been started " + counter + " times.");
        
        // Increment the counter
        SharedPreferences.Editor editor = app_preferences.edit();
        editor.putInt("counter", ++counter);
        editor.commit(); // Very important
    }
        
    
}

Integrate AdMob in Android

How to Integrate AdMob in android device??

First of all open project.Properties file and set target to 15

# This file is automatically generated by Android Tools.
# Do not modify this file -- YOUR CHANGES WILL BE ERASED!
#
# This file must be checked in Version Control Systems.
#
# To customize properties used by the Ant build system use,
# "ant.properties", and override values to adapt the script to your
# project structure.
# Project target.
target=android-15

Now download GoogleAdMobAdsSdk-4.3.1.jar file and copy & paste it into your project.

Then Select your project--> Right Click-- > Properties --> Java Build path --> Libraries --> Add JARs --> select your project from list and select that GoogleAdMobAdsSdk-4.3.1.jar fiel --> ok

        // Lookup your LinearLayout assuming it’s been given
        // the attribute android:id="@+id/mainLayout"
        LinearLayout layout = (LinearLayout) findViewById(R.id.mainLayout);

        // Add the adView to it

Create Option Menu for Android device

We are going to create option menu when user touches option on device one menu will displayed like, Help and about Us.

DeviceOptionsMenuActivity.java (Main activity)

package pkg.DeviceOptionsMenu;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.Window;

public class DeviceOptionsMenuActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.main);
    }
   
    public boolean onCreateOptionsMenu(Menu menu) {
       
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.my_options_menu, menu);
        return true;
    }
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
        case R.id.about:
        startActivity(new Intent(this, About.class));
        return true;
        case R.id.help:
        startActivity(new Intent(this, Help.class));
        return true;
        default:
        return super.onOptionsItemSelected(item);
        }
    }
}

AboutUs.java

package pkg.DeviceOptionsMenu;

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

public class About extends Activity {
   
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.about);
    }
   

}
 

Help.java

package pkg.DeviceOptionsMenu;

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

public class Help extends Activity {
   

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.help);
    }
}
 

Dont change main.xml keep it as it is..we dont need that one for our example.

Now Create about.xml

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

   
        <RelativeLayout
            android:id="@+id/relativeLayout1"
            android:layout_width="fill_parent"
            android:layout_height="280dp"
            android:layout_weight="0.19" >

            <TextView
                android:id="@+id/textView1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentTop="true"
                android:layout_centerHorizontal="true"
                android:layout_marginTop="139dp"
                android:textSize="9pt"
                android:text="This Application is sponsored by"
                android:textAppearance="?android:attr/textAppearanceMedium"
                android:textColor="#717C40" />

            <TextView
                android:id="@+id/textView2"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignLeft="@+id/textView1"
                android:layout_below="@+id/textView1"
                android:textSize="8pt"
                android:text="Ronak Pandya"
                android:textAppearance="?android:attr/textAppearanceMedium"
                android:textColor="#717C40" />

            <TextView
                android:id="@+id/textView3"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignLeft="@+id/textView2"
                android:layout_below="@+id/textView2"
                android:textSize="8pt"
                android:text="You are free to use it."
                android:textAppearance="?android:attr/textAppearanceMedium"
                android:textColor="#717C40" />

            <TextView
                android:id="@+id/textView4"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignLeft="@+id/textView3"
                android:layout_centerVertical="true"
                android:textSize="8pt"
                android:text="Please contact us at,"
                android:textAppearance="?android:attr/textAppearanceMedium"
                android:textColor="#772020" />

            <TextView
                android:id="@+id/textView5"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignLeft="@+id/textView4"
                android:layout_below="@+id/textView4"
                android:textSize="8pt"
                android:text="support@support.com"
                android:textAppearance="?android:attr/textAppearanceMedium"
                android:textColor="#0F53FF" />
        </RelativeLayout>
 
</LinearLayout>

help.xml (Write whatever content you want to write....)

<?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>

Now Create a dir called menu--> in that create xml file called my_options_menu.xml in

i.e res/menu/my_options_menu.xml

my_options_menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/about"
android:title="About" />
<item android:id="@+id/help"
android:title="Help" />
</menu>

Finally Add Both activities Help and about.java to AndroidMenifiest.xml file 

Run it...
