Best practices Android Resposiveness : Using background Intent service for background job

An IntentService isn't affected by most user interface lifecycle events, so it continues to run in circumstances that would shut down an AsyncTask.

Creating a background services

Create a class RSSPullService and extends IntentService to create component IntentService

          public class RSSPullService extends IntentService {
    protected void onHandleIntent(Intent workIntent) {
        // Gets data from the incoming Intent
        String dataString = workIntent.getDataString();
        // Do work here, based on the contents of dataString

Define IntentService with application Manifest

Create a background work request and send it to IntentService

Create a new, explicit Intent for the IntentService called RSSPullService.

mServiceIntent = new Intent(getActivity(), RSSPullService.class);

Call startService()

// Starts the IntentService

Fun time : Five reason to hate beautiful android

Everyone around me having android in their hand

Off course everyone around me have android in their hand and i am fed up of being one of them. I want to look different so i am switching to costly iPhone which gonna change my status among people around. Even its easy to be identify, people generally say "Ohh you'r talking about guy with iPhone".

Android is open source and vulnerable to security of personal data

Even i don't care if somebody try to explain me that android is no less secure than windows and ios. I am smart enough to secure my personal data even i don't have any. I like apple annoying pop up for asking permission again and again.

I don't like customization of home screen in android

Come on we are using smartphone so why to allow user to customize home screen ? I like rigid way of iPhone and windows. I don't like change at all so i love iOS and windows

Being a philanthropist i always support sinking ship

I was big fan of android when Google launch it. But when i see iOS start dying and windows crawling, i almost cry that day. Then i decided no matter what android do, i will support windows and iOS. Even i continue forced my all relative to use expensive iOS untill they kick on my ass.

I hate android for no reason

OK ! I am free to do what i want, so do i hate damn beautiful android and its huge app market.
Note : This article is written for fun. Keep this in mind

WRITE_EXTERNAL_STORAGE permision limit to primary memory acess : Weirdest update of Android KitKat 4.4

Post Address Issue -

  • WRITE_EXTERNAL_STORAGE  doesn't work with Android KitKat 4.4
  • Android KitKat 4.4 doesn't allowing writing to secondary storage
  • Error accessing the SD card on Android KitKat (4.4.x)

I had gone through Weirdest  issue recently, My app suddenly got bad reviews as  app is not working with Android KitKat 4.4 and above. I dig out and find problem, My android application was not able to read from android secondry memory storage (i.e called Sdcard also.). Android KitKat 4.4 support WRITE_EXTERNAL_STORAGE  in certain manner now.

Interesting point for KitKat is that writing to secondary external storage (such as SD memory card) is prohibited, except of app's specific directory, which is deleted during app uninstall.Only solution to this problem is to get your phone rooted.

Google Android cleary says

The WRITE_EXTERNAL_STORAGE permission must only grant write access to the primary external storage on a device. Apps must not be allowed to write to secondary external storage devices, except in their package-specific directories as allowed by synthesized permissions. Restricting writes in this way ensures the system can clean up files when applications are uninstalled.

If your phone is rooted you will have access to /system/etc/security/permissions.xml . media_rw is clearly missing here

<permission name="android.permission.WRITE_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
<group gid="sdcard_rw" />
<group gid="media_rw" />

still its not clear why Google android KitKat 4.4 has logic behind this Weirdest . See Reported BUG to Android 4.4 does not allowing writing to secondary storage.

WebView Scroll Vertically : WebView scroll in one direction after zoom in android

Android WebView allow to load HTML content. Recently i was facing issue regarding zoom of WebView. What my requirement was, for scroll WebView content vertically regardless of its zoom level. Simply i want to stop horizontal scroll of webview.
I came across meta tag ViewPort and it did a lot of help with some attribute of WebSettings dynamically.

  • Wrap WebView inside ScrollView
  • Meta Tag viewport : Attach this meta tag immediately after <head>

<meta name="viewport" content="width=device-width,height=device-height,target-densityDpi=device-dpi,user-scalable=yes,initial-scale=0.5, maximum-scale=2, minimum-scale=0.5" />

If you don't have control on HTML content, then read HTML content in one string and then append above tag and then write to file again or use with webview's method loadwithBaseURL

StringBuilder mBuilder = new StringBuilder(mBuffer.toString().replace("<head>",
"<head><meta name=\"viewport\" content=\"width=device-width,height=device-height,target-densityDpi=device-dpi,user-scalable=yes,initial-scale=0.5, maximum-scale=2, minimum-scale=0.5\" />"));

mBuffer is the HTML string. you can change WebView's scale according to requirement

  • Attribute need to set dynamically are 


where view is reference of WebView.

Achieve Through this Article 

  •  Content will fit to new line to scroll WebView only vertically
  •  Fit content to initial scale using Meta Viewport
  • Content will not go more than WebView width

Samsung to launch Tizen O.S : Why South Korean giant Samsung choose India?

Samsung is going to launch Tizen new mobile o.s in India on new sub-$100 smartphone. They had a plan to launch it in Russia but they scrap the plan. Samsung mostly device are running android o.s platform. Android is responsible for their recent success over Apple. They thoroughly enjoyed selling their overprice devices but cheap compare to Apple iPhone. But now they are coming up with their own Tizen operating System.

Why they choose specifically India?

India had a huge market which is not still explored totally so they had huge opportunity to reach out million of customer with their Tizen mobile operating. Its kind of beta phase and they don't want to cost their prime customer in USA and Europe with developing O.S. Indian are pretty much price sensitive and they will buy Tizen loaded device with $100 (INR 6000). In recent survey, its stated that Indian smart phone user prefer low end and cheap device and they never complain about quality of product. And Samsung choose rightly this point and in the mean time they will try to improve Tizen before they go to USA or Europe.

There is section in India which has capability of purchase high end phone and those will not give a shit to $100 Tizen phone.

Its will be good to see weather Samsung can survive without Android !

Motorola Google Nexus 6 Launch : A big no to 5.9 Inch android phone

LG  collaboration wit Google provide us a good nexus 5, which is still amazing phone. It has been a long time around til the day nexus 5 was launched. But still price of android nexus 5 is not down like Samsung devices.
Now there are rumor about nexus 6(Nexus X) will be a Motorola. Motorola has taken android market by storm with their two device Moto X and Moto G.

 According to AnTuTu, the handset will be running Android 5 L, have a 5.9in QHD screen, Qualcomm Snapdragon 805 SoC processor and 3GB of RAM. Which is surely quite impressive. 

The key point of Nexus 6 is its bulky size of 5.9 inch, which obviously a Phablet. Google may have decide to try their hand in Phablet. Nexus is undoubtedly favorite phone among android lover because of its latest update, Google flagship and handy design. I never see a Nexus lagging anywhere.

 Is Google mistaking by competing with Samsung note series ?

  •  I talk to many existing android user who have a thought about Nexus 6, And they say Big no to this. And main cause was its bulky size. Samsung had targeted  corporate user via Note series which commendable. Samsung has fragment user base , but Nexus doesn't. 

  •  Second, Samsung had worked hard to customize and optimize android O.S to fit requirement of bigger Phablet. So performance are surely good. I doubt Goolge and Motorola can spend such amount of time on this.

 Release date of Nexus 6

 Google Nexus 6 is expected to launch around same time(October) when Nexus 5 was launched. This will launch with Android L version of android.

Customizing Support Android Action bar Tab : and Action Bar

Action Bar is integral part of android design guidelines. Action Bar API was intruduces in android version 3.0 and above but few months ago Google launch backward compatibility support for ActionBar with Support v7 library. Here see Action Bar Tab integration with Fragment

I have gone through some customization of Support Action Bar android Action Bar. So here I am sharing those piece of source code which help me to beautify Android Action Bar

Action Bar Background Color -

   <!-- ActionBar styles -->  
   <style name="MyActionBar" parent="@style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">  
     <item name="android:background">@color/name</item>  
     <!-- Support library compatibility -->  
     <item name="background">@color/name</item>  

Action Bar Title Text Customization

   <!-- ActionBar styles -->  
   <style name="MyActionBar" parent="@style/Widget.AppCompat.ActionBar">  
     <item name="android:titleTextStyle">@style/MyActionBarTitleText</item>  
     <!-- Support library compatibility -->  
     <item name="titleTextStyle">@style/MyActionBarTitleText</item>  
   <!-- ActionBar title text -->  
   <style name="MyActionBarTitleText" parent="@style/TextAppearance.AppCompat.Widget.ActionBar.Title">  
     <item name="android:textColor">@color/tabText</item>  
     <!-- The textColor property is backward compatible with the Support Library -->  

Action Bar Tab Customization

  • Action Bar Tab Text Customization

   <!-- ActionBar tabs text -->  
   <style name="MyActionBarTabText" parent="@style/Widget.AppCompat.ActionBar.TabText">  
     <item name="android:textColor">@color/tabText</item>  
     <!-- The textColor property is backward compatible with the Support Library -->  

  • Action Bar Tab's View and Selector Customization - Action bar Tab View can be customize. You can use your own custom view or set custom selector align Tab Text, and Change padding of Tab Text inside action bar Tab

   <!-- ActionBar tabs styles -->  
   <style name="MyActionBarTabs" parent="@style/Widget.AppCompat.ActionBar.TabView">  
     <!-- tab indicator -->  
     <item name="android:background">@drawable/tab_selector</item>  
     <!-- Support library compatibility -->  
     <item name="background">@drawable/tab_selector</item>  
     <item name="android:paddingLeft">0dp</item>  
     <item name="android:paddingRight">0dp</item>  
     <item name="android:paddingTop">0dp</item>  
     <item name="android:paddingBottom">0dp</item>  

Here how you create Tab Selector XML to apply all effect (i.e Selected,Pressed,Unselected) – All Images should be placed rightly in drawables

 <?xml version="1.0" encoding="utf-8"?>  
 <selector xmlns:android="">  
   <item android:drawable="@android:color/transparent" android:state_focused="false" android:state_pressed="false" android:state_selected="false"/>  
   <item android:drawable="@drawable/tab_selected_example" android:state_focused="false" android:state_pressed="false" android:state_selected="true"/>  
 -   <!-- Focused states -->  
   <item android:drawable="@drawable/tab_unselected_focused_example" android:state_focused="true" android:state_pressed="false" android:state_selected="false"/>  
   <item android:drawable="@drawable/tab_selected_focused_example" android:state_focused="true" android:state_pressed="false" android:state_selected="true"/>  
 -   <!-- Pressed -->  
 -   <!-- Non focused states -->  
   <item android:drawable="@drawable/tab_unselected_pressed_example" android:state_focused="false" android:state_pressed="true" android:state_selected="false"/>  
   <item android:drawable="@drawable/tab_selected_pressed_example" android:state_focused="false" android:state_pressed="true" android:state_selected="true"/>  
 -   <!-- Focused states -->  
   <item android:drawable="@drawable/tab_unselected_pressed_example" android:state_focused="true" android:state_pressed="true" android:state_selected="false"/>  
   <item android:drawable="@drawable/tab_selected_pressed_example" android:state_focused="true" android:state_pressed="true" android:state_selected="true"/>  

Now give all theme Reference to main theme and use this theme for any activity in Android manifest 

   <style name="AppBaseTheme" parent="@style/Theme.AppCompat.Light">  
     <item name="android:actionBarStyle">@style/MyActionBar</item>  
     <!-- Support library compatibility -->  
     <item name="actionBarStyle">@style/MyActionBar</item>  
     <item name="android:actionBarStyle">@style/MyActionBar</item>  
     <item name="android:actionBarTabTextStyle">@style/MyActionBarTabText</item>  
     <item name="android:actionMenuTextColor">@android:color/background_light</item>  
     <!-- Support library compatibility -->  
     <item name="actionBarStyle">@style/MyActionBar</item>  
     <item name="actionBarTabTextStyle">@style/MyActionBarTabText</item>  
     <item name="actionMenuTextColor">@color/tabText</item>  
     <item name="android:actionBarTabStyle">@style/MyActionBarTabs</item>  
     <!-- Support library compatibility -->

Android FTP client tutorial with example of uploading, downloading and authentication with FTP server

FTP protocol is standard network protocol for transferring file. It works on peer to peer base network. In recent days I had written few articles about file transfer protocol and comparison among them to choose best. After research, research shows that FTP outperformed everything in android. So I decide to write about FTP client implementation. This tutorial will teach you
  • Android FTP client Authentication - How to connect with FTP server?
  • Android FTP client Download - How to download a file from FTP server?
  • Android FTP client Upload -How to upload a file to FTP server?

Basic requirement for this tutorial is one simple FTP server setup at your desktop. You can use file-Zilla or IIS server for this requirement.

  • Android FTP client authentication and listing file from FTP server

       * @param ip  
       * @param userName  
       * @param pass  
      public void connnectingwithFTP(String ip, String userName, String pass) {  
           boolean status = false;  
           try {  
                FTPClient mFtpClient = new FTPClient();  
                mFtpClient.setConnectTimeout(10 * 1000);  
                status = mFtpClient.login(userName, pass);  
                Log.e("isFTPConnected", String.valueOf(status));  
                if (FTPReply.isPositiveCompletion(mFtpClient.getReplyCode())) {  
                     FTPFile[] mFileArray = mFtpClient.listFiles();  
                     Log.e("Size", String.valueOf(mFileArray.length));  
           } catch (SocketException e) {  
           } catch (UnknownHostException e) {  
           } catch (IOException e) {  

  • Android FTP client download a file from FTP server – you can browse through directory saved on FTP server and can download desired file or directory. I just write code here for downloading a single file and writing it to sdcard/phone memory.

Best file transfer protocol : Which to use among SMB, Socket (TCP/UDP) and FTP?

I had gone through the requirement of file transfer using peer to peer in a same network. I tried the case of server and client too because I had not any issue to run server script (in case of Socket Connection). Main purpose was to attain maximum transfer speed of data. So I tried with three most popular protocols for file transfers which are –
  • SMB – Server Message Protocols known also as sambha file sharing
  • Socket- Work on the base of client server concept
  • FTP- File transfer protocol

Comparison for performance –

Max Speed
1.3 GB
5 Meter
16 Min
1.3 MB/S
0.7 GB
5 Meter
25 Min
0.5 MB/S
1.3 GB
5 Meter
14 Min
1.6 MB/S

Notable Point about file transfer protocols –

  • Socket – Server scripting required for file transfer. This connection cannot be named as peer to peer
  • SMB – No scripting required for file transfer. It can read any file structure of peer computer
  • FTP FileZilla can do the trick for file transfer. No Server script required

Term and Condition – These all testing has been done between an android and a low configuration desktop (Windows 7). Both were connected to one dedicated wifi local network

Android sambha/ JSIFS file sharing example and source code

Look at ES File explorer functionality of connecting to peer computer (either android or Desktop) and reading file structure of that device on your own device to copy content. I just implemented this functionality using SMB file sharing system in android. I will explain with source code and example. You can connect to any peer computer using its IP and password. It will allow you to read full directory of this computer. This process is called peer to peer connection.

  • Why to use Sambha File Sharing system

           For making file sharing system like ES Android file explorer which connect peer device on LAN

You will need IP and Password of that peer which you want to connect through SMB file transfer system.
Connecting android with peer using SMB file sharing -

      public void connectingWithSmbServer() {  
           try {  
                String yourPeerPassword = "administrator";  
                String yourPeerName = "abcd1234";  
                String yourPeerIP = "";  
                String path = "smb://" + yourPeerIP;  
                NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(  
                          null, yourPeerName, yourPeerPassword);  
                Log.e("Connected", "Yes");  
                SmbFile smbFile = new SmbFile(path, auth);  
                /** Printing Information about SMB file which belong to your Peer **/  
                String nameoffile = smbFile.getName();  
                String pathoffile = smbFile.getPath();  
                Log.e(nameoffile, pathoffile);  
           } catch (Exception e) {  
                Log.e("Connected", e.getMessage());  

Once you connected you can browse through the file system easily and you can download any file from peer to android sdcards. Once see below code to download file from peer to android sdcard using SMB file sharing system -

      public void downloadFileFromPeerToSdcard(File mLocalFile, SmbFile mFile) {  
           try {  
                SmbFileInputStream mFStream = new SmbFileInputStream(mFile);  
                mLocalFile = new File(Environment.getExternalStorageDirectory(),  
                FileOutputStream mFileOutputStream = new FileOutputStream(  
                byte[] buffer = new byte[1024];  
                int len1 = 0;  
                while ((len1 = > 0) {  
                     mFileOutputStream.write(buffer, 0, len1);  
           } catch (MalformedURLException e) {  
                Log.e("MalformURL", e.getMessage());  
           } catch (SmbException e) {  
                Log.e("SMBException", e.getMessage());  
           } catch (Exception e) {  
                Log.e("Exception", e.getMessage());  

Note : Keep all methods inside background thread (i.e Asynchronous Task, Service)

You need to add one JSIFS Sambha jar file. Enjoy
