A lot of friends have asked me to help them build an Android Wallpaper. To people who have HD pictures and want to build their own Android Wallpaper apps, an Android app template will be very helpful. So I give you this Android Naruto HD wallpaper app. I figured I should sell the source code cheap so that more people will be able to access it and make easy money on it.

Compare to write the Android app source code line by line, using an Android App template is really basic and really cheap. As long as you have HD photos or Wallpapers, you can easily replace images in this app template. Within 5 minutes, you will get your own Android app ready to make money in your Google Play account or with your AdMob ads banner.

With this Wallpaper Android app template, you can customize the look and feel to make like 20 stand-alone Wallpaper apps if you want. Or you can put all HD wallpapers in one app.

If you want to test this app yourself, you can download and install it by following link, or scan the QR code to download and install on your android phone directly.

Memo English Fruit Master

In last month, I have created a new Android app, Memo English: Fruit Master. The purpose of this app is helping me to remember some fruits name in English. I collect 75 most common fruits in this app. Some of them are quite challenge actually. In this app, you can learn the fruit name in English, listen the voice over and do some spelling practice to remember the English word. Currently, I am using Google Translate to localize this app in Spanish, Russian, Korean, Chinese, and Vietnamese.

Create Transparent PNG Image in PHP

This is a very old topic. When I search this title online, I can get some articles which are published as early as 2003. Though there are so many reference, it still takes me a huge amount of time to figure this out when I am working on my open source project “Free Online Sprite Sheet Decomposer“. The concept of this project is dividing the PNG sprite sheet into pieces of frame by frame png files. The challenge is copying the color info from source image to the destination image and keeping the transparent info as the same. However, PNGs have several different types and each type supports the transparency feature in different way. For more details, you can check this article: Transparency Concept in PNG.

Transparency Concept in PNG

Transparency-In-PNG

Transparency is fully supported in PNG, but it is very complicated to manipulate in program. PNG supports three main types: truecolor(rgb or 24-bit), grayscale, and palette-based(8-bit). All of them can have alpha information, but it’s most commonly used with truecolor image. The truecolor (RGB) PNGS, are supported in only two depths: 8 and 16 bits per sample (for each pixel, generally 8 bits or 16 bits are used for each channel), corresponding to 24 and 48 bits per pixel. Normally, the truecolor is 24 bits per pixel. The truecolor png with alpha channel is known as RGBA (32-bit). This transparency feature is important to create special effects such as making a central oval region fully opaque, the outer regions fully transparent, and the transition region that varies smoothly between the two extremes. A real case is a square picture with a solid red ball with shadow. The solid red ball is fully opaque, the shadow is transition region, the rest of space is fully transparent.

Core data is the simplest way to save and load local data in ios apps. In previous tutorial, I already gave some example source code to show you how efficient it is to save data in core data. I am pretty sure you will get more exciting once you see how easy to fetch data form core data and filter core data results.

In last tutorial, we successfully create a new iOS project with Core Data Framework. We also design a Managed Object Model in the Xcode data model design tool and automatically generate the classes associated with the entities in the model. So, in this post, we will continue doing the app and I will show you how to initialise the managed object model in the app and how to save save data by core data.

IOS Core Data Example With Sample Code

IOS core data is the most efficient way to save and load data in iPhone and iPad app. It is also more complicated than another ways such as NSUserDefaults or NSFileManager. The best way to help us fully understand how IOS core data works is writing an real project. In this tutorial, I will design a simple iPhone app to demonstrate the whole process of using core data in iOS app. The process includes:

  • How to design the data structure with core data
  • How to initialise the core data
  • How to add data in core data
  • How to fetch data from core data
  • How to fetch data from core data by filter

Before we start the core data tutorial, let me briefly describe this small app first. This app will store 4 people’s information by using core data framework. The information includes name, password, gender, email and address. The main features of this example app is showing people’s information and search people by name. All above tasks will be implemented by core data framework.
