Android-SharedPreference-Example

Hi Friends

       Today i am going to explain Android SharedPreferences.

Android SharedPreferences:

Android supports the usage of the SharedPreferences class for persisting key-value pairs (preferences)of primitive data types in the Android file system.

The definition of these preferences can be done via an XML resource.

The PreferenceManager class provides methods to get access to preferences stored in a certain file. 

Step to Create SharedPreference:-

1. create object of SharedPreference in following way.

SharedPreferences spref = (SharedPreferences)PreferenceManager.getDefaultSharedPreferences(this);

2. Getting value from SharedPreference:

count = spref.getInt("appcount", 0);

3. Setting new value for preference:

SharedPreferences.Editor editor = spref.edit();

       editor.putInt("appcount", count);

        editor.commit(); // Very important

Now i am going to explain shared preference with very simple example that count how many times your application open.

Java Source code for application:-

package in.androidshivendra.sharedpreferenceexample; import android.os.Bundle; import android.preference.PreferenceManager; import android.app.Activity; import android.content.SharedPreferences; import android.view.Menu; import android.widget.TextView; import android.widget.Toast; public class MainActivity extends Activity { TextView tv; SharedPreferences spref; int count ; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); spref= (SharedPreferences)PreferenceManager.getDefaultSharedPreferences(this); count = spref.getInt("appcount", 1); tv = (TextView)findViewById(R.id.textView1); tv.setText("you have "+count+"time open it"); count++; SharedPreferences.Editor editor = spref.edit(); editor.putInt("appcount", count); editor.commit(); // Very important } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } }

Layout xml code:-

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:paddingBottom="@dimen/activity_vertical_margin"

    android:paddingLeft="@dimen/activity_horizontal_margin"

    android:paddingRight="@dimen/activity_horizontal_margin"

    android:paddingTop="@dimen/activity_vertical_margin"

    tools:context=".MainActivity" >

   

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:text="@string/hello_world" />

   

        android:id="@+id/textView1"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_centerHorizontal="true"

        android:layout_centerVertical="true"

        android:text="Large Text"

        android:textAppearance="?android:attr/textAppearanceLarge" />

Simple-Android-PhoneGap-Example

Simple Android Phone Gap Application Example

Hi Friend
           We know that Phone Gap  provide facility to create Hybrid (cross plat form) application. In phonegap we create application using HTMLt5, CSS3 and JavaScript.

            Now i am going to explain how to create simple android phone gap exaple application using eclipse IDE.

you can download phone-gap SDK  here.

Step 1: First of all download phonegap SDK and extract Director structure like this.

click on lib

click on andorid
 

Now create an android application:

                              1. create www name folder in assets folder.
                              2. create index.html file with www folder that created previously.
                              3. Copy from \phonegap-2.3.0\lib\android\ cordova-2.3.0.js file and patse in www folder.
                               4.Copy from \phonegap-2.3.0\lib\android\cordova-2.3.0.jar file and paste in project lib folder and add to build path.
                               5. Copy from \phonegap-2.3.0\lib\android\xml folder and paste it into res folder.

Now your project file directory structure look like this.

Now open your java file and write code like this:

package in.android.androidphonegapexample;

import org.apache.cordova.DroidGap;

import android.os.Bundle;

public class MainActivity extends  DroidGap {

  

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        super.loadUrl("file:///android_asset/www/index.html");

    }

   

} 

Now open your application manifest.xml file and add these code.

add these code in activity tag android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale"

Now Run Your application you got out put like this:-

Android-Phonegap-Overview

Dear Friend
         In this post i have explain  knowledge about phone-gap application using Android. It is very simple.
But first of all i want write some information about phone-gap.

1. What is phone gap?

ans: 
       phone is  an open-source mobile application development framework,that offers programmers to build applications for mobile devices using JavaScript, HTML 5, and CSS 3, instead of device-specific languages such as Objective-C

2. What are characteristic of phone gap?

ans: The phone-gap application characteristic :
        The resulting applications are hybrid, meaning that they are neither truly native (because all layout rendering is done via web views instead of the platform's native UI framework) nor purely web-based (because they are not just web apps, but are packaged as apps for distribution and have access to native device APIs).

Conclusion about Phone-gap: phone-gap facilitate us to write cross platform mobile application.

you can get knowledge about phone gap here.

you can download phone-gap SDK  here.

you can download latest phone-gap SDK here.

Splash-screen-activity-example-in-android

Simple Splash Screen Activity Example using ProgressBar

In this example i explained how to create splash screen in android.

To create Splash screen we have to use sleep method on Main Thread. i have design it and after completing activity another screen open.

To create this example you have to create two activity 1. SplashActivity ii. HomeActivity

Java Source code for splash screen :

1. SplashActivity.java:

package in.androidshivendra.projectmodel;

import android.os.Bundle;

import android.app.Activity;

import android.content.Intent;

import android.view.Menu;

import android.widget.ProgressBar;

public class SplashActivity extends Activity {

int i =0 ;

ProgressBar pb;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_splash);

pb  = (ProgressBar)findViewById(R.id.progressBar1);

Thread t = new Thread(new Runnable() {

@Override

public void run() {

// TODO Auto-generated method stub

for(i=0;i<=100;i++)

{

pb.setProgress(i);

try {

Thread.sleep(100);

if(i==100)

{

Intent i = new Intent();

i.setClass (SplashActivity.this,HomeActivity.class);

startActivity(i);

}

} catch (InterruptedException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}

});

t.start();

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.splash, menu);

return true;

}

@Override

protected void onPause() {

// TODO Auto-generated method stub

finish();

super.onPause();

}

}

Xml layout code:-

    xmlns:tools="http://schemas.android.com/tools"

    android:id="@+id/LinearLayout1"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

Android Upload Image

Android Upload Image

Hi Friend
       Today i am going to explain how to upload image on application server using android.
There are two part for creating such type application.
1. Server part
2.android application creation

Server Part :

To work with Application Server you required knowledge about server programming language (like jsp, php, Asp etc). i have used PHP script.

Step 1:
         Open any text editor and write php script code that written below and save with index.php and also create a folder named uploads location C:\xampp\htdocs\

    $file_path = "uploads/";
   
    $file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
    if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
        echo "success";
    } else{
        echo "fail";
    }
 ?>

Android Application creation

Step 2:
        Create an android applcation.

     android:orientation="vertical"

     android:layout_width="fill_parent"

     android:layout_height="fill_parent"

     >

Required Permission are:

i.   android.permission.READ_EXTERNAL_STORAGE
ii. android.permission.INTERNET

To run this example you have to put an image file name a.jpg  in sdcard.

Step 3: Send image in emulator sdcard.

 i. start emulator and open file explorer by this way:-

ii. click on windows-> showview-> other-> android-> fileexplorer

iii. you got window like this

Now Run Application :-

   

Image Upload Process start

Image Uploading complete.

Basically your file is store in C:\xampp\htdocs\uploads folder

NOTE: THIS APPLICATION ONLY RUN WITH EMULATOR, to test this application on phone or blue stack then you have to chage Image path.

final String uploadFilePath = "/mnt/sdcard/";

    final String uploadFileName = "a.jpg";
according to current file location.
