How To publish android application in market.

Process of publish an application in the android market (Google-Play).

Android Market:

            https://play.google.com/store

Android Market now called Google Play is a digital-distribution multimedia-content service from Google which includes an online store for music, movies, books, and Android applications and games, as well as a cloud media player.

For publishing the application in the market we need to check the following points:

·         Getting application ready

a.       Request necessary android permission

b.      Specify a name and icon

c.       Configure  version manifest data

d.      Set compatibility option

e.       Cleanup file and removing logging

f.       Sign in and zip align the application

·         Becoming a market publisher

a.       Register as a publisher and setup your profile

b.      Read and agree to the Android Market Developer Distribution Agreement.

c.       Pay a registration fee of $25 USD via Google Checkout.

To publish applications on the Android Market, you must be a registered developer. Head over to http://market.android.com/publish and sign in with your Google account. Next, fill out all the required information along with your real phone number, which Google will use to contact you in the event of an emergency or a problem with any of your Android applications. If you can’t decide on a developer name, don’t worry. Just use your real name for now – you can always change that later via your profile page.

You should read the Android Market Developer Distribution Agreement carefully, as you are required to accept the terms and you will be legally bound to them upon paying the registration fee.

Click the Google Checkout button and pay the one-time registration fee and you’re done!

·         Uploading an application

Login to your publisher account and click “Upload an Application”. Fill in all of the form data and include screenshots if you can and provide a precise, short and well-formatted description. You can also choose whether or not you want to release it as a free or paid app – though you need to be a registered Google Checkout Merchant to do the latter and it’s currently only available in a handful of countries. Lastly, click “Publish.”

Check Internet Connection in Android

       public boolean isOnline() {

              ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

              NetworkInfo netInfo = cm.getActiveNetworkInfo();

              if (netInfo != null && netInfo.isConnectedOrConnecting()

                           && cm.getActiveNetworkInfo().isAvailable()

                           && cm.getActiveNetworkInfo().isConnected()) {

                     return true;

              }

              return false;

       }

there another method you want to use 

       public static boolean haveNetworkConnection(final Context context) {

              boolean haveConnectedWifi = false;

              boolean haveConnectedMobile = false;

              final ConnectivityManager cm = (ConnectivityManager) context

                           .getSystemService(Context.CONNECTIVITY_SERVICE);

              if (cm != null) {

                     final NetworkInfo[] netInfo = cm.getAllNetworkInfo();

                     for (final NetworkInfo netInfoCheck : netInfo) {

                           if (netInfoCheck.getTypeName().equalsIgnoreCase("WIFI")) {

                                  if (netInfoCheck.isConnected()) {

                                         haveConnectedWifi = true;

                                  }

                           }

                           if (netInfoCheck.getTypeName().equalsIgnoreCase("MOBILE")) {

                                  if (netInfoCheck.isConnected()) {

                                         haveConnectedMobile = true;

                                  }

                           }

                     }

              }

              return haveConnectedWifi || haveConnectedMobile;

       }

=============================================================

         if (haveNetworkConnection(Activity.this))

           {

                //Conneced

           }

       else

           {

                //No Connected

           }

Note:- you also give User Permission

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Convert String in to base64 in Android

Convert String in to base64 in Android

byte[] data;

              String str = "xyzstring";

              try {

                     data = str.getBytes("UTF-8");

                     String base64 = Base64.encodeToString(data, Base64.DEFAULT);

                     Log.i("Base 64 ", base64);

              } catch (UnsupportedEncodingException e) {

                     e.printStackTrace();

              }

Base 64 of "xyzstring" is “eHl6c3RyaW5n”

SharedPreference example in Android

 SharedPreference example in Android

Application shared preferences allows you to save and retrieve data in key, value pair.
Initialization of SharedPreference in Android:.

Application shared preferences can be fetched using getSharedPreferences() method.The following code can be used to get application shared preferences.

       SharedPreferences pref = getApplicationContext().getSharedPreferences(

                           "any_prefname", MODE_PRIVATE);

Available mode for shared preference:

• MODE_WORLD_READABLE
• MODE_WORLD_WRITEABLE
  
• MODE_PRIVATE
  

To edit sharedpreference value, we need editor to edit and save the changes in shared preferences.

Editor editor = pref.edit();

and to save data commit() is used.

Editor.commit();

You can save data into shared preferences using editor. All the primitive data types like booleans, floats, ints, longs, and strings are supported. Call editor.commit() in order to save changes to shared preferences.

              editor.putBoolean("key_name", true); // Storing boolean - true/false

              editor.putString("key_name", "string value"); // Storing string

              editor.putInt("key_name", "int value"); // Storing integer

              editor.putFloat("key_name", "float value"); // Storing float

              editor.putLong("key_name", "long value"); // Storing long

         editor.commit(); // commit changes

Get data from Shared Preference:

Data can be retrived from saved preferences by calling getString() (For string) method.for boolean getBoolean() Remember this method should be called on Shared Preferences not on Editor.

// returns stored preference value

// If value is not present return second param value - In this case null

              pref.getString("key_name", null); // getting String

              pref.getInt("key_name", null); // getting Integer

              pref.getFloat("key_name", null); // getting Float

              pref.getLong("key_name", null); // getting Long

              pref.getBoolean("key_name", null); // getting boolean

Delete data from shared preference and delete sharedpreference:

To delete data from shared preferences we can use remove(“key_name”).If we want to delete all the data, call clear()

editor.remove("student_name");//will delete student_name editor.commit();

Following will clear all the data from shared preferences

editor.clear(); editor.commit();
