Android Essentials: Creating Android-Compliant Libraries - Tuts+ Code Tutorial - 1 views

  •  
    For a library to be compatible with Android, it can only reference classes available as part of Android and other classes implemented specifically in the library itself.Android Libraries can contain Java classes, resources, and other project information, but not assets. They can reference other libraries and leverage third party JAR files. They have Android manifest files just like regular Android projects. However, they differ from normal Android projects in an important way: they cannot be compiled into their own application packages or deployed onto devices. They can also not be exported as standalone JAR files. Once referenced from an Android project, the library components are incorporated into the Android application that references them at build time and added to the application package. There is no need to declare the component as the library classes are rolled into the APK directly. In terms of compatibility, the Android project must have an API Level higher than or equal to the API Level set in the Android library.

Android Cookbook: Home - 0 views

  •  
    "We are building a community-written web site which has also been used to create an O'Reilly Cookbook, both about how to build great Android applications. It is full of how-to information along with code snippets that illustrate the ideas presented. It features both how-to's that overlap with the official documentation, and material that goes beyond this to be more tutorial, more in-depth, or explaining "lessons from the trenches": what actually works to get the application functioning well. Unlike most books written by one, two or a few individuals, this one has input from dozens of contributors, who were all able to view and comment on each others' recipes before the book was published. The published version(s) include printed books, eBooks, and other uses"

Card UI - 0 views

  •  
    "Ever wondered about Google play store UI which is built around cards. Card is nothing but a single row item of ListView or GridView. As depicted below, card can be of various sizes and can be either app card, movie, books, games or app suggestions card or birthday card or even it can be a simple list/grid item too. The main benefit of designing app with card UI is it gives consistent looks throughout the application, doesn't matter whether it gets loaded in mobile or tablet."

Android Fragmentation Visualized - OpenSignal - 1 views

  •  
    "Fragmentation matters to the entire Android community: users, developers, OEMs, brands & networks. It's a blessing and a curse. The Blessing. Fragmentation allows users to take their pick from thousands of devices. You can choose from phones with 3D screens, projectors, CDMA, GSM, or even CDMA & GSM. You may not care that Tag Heuer has made an Android phone but at least one person does (and they use OpenSignalMaps). It's a triumph for Android that as a single OS it can target so many markets. The Curse. The proliferation of devices with their associated screen sizes, internal hardware and custom ROMs creates some difficulties. We spend a lot of time making the app presentable (or at less functional) on exotic devices - this is the most common request we get from app users"

Google strengthens Android security muscle with SELinux protection | Ars Technica - 0 views

  •  
    The other big security enhancement introduced in Android 4.3 is a more robust way to store cryptographic credentials used to access sensitive information and resources. This means changes to the Android KeyChain, which stores digital certificates used to access Wi-Fi networks and virtual private networks used by large corporations and government agencies. With the keychain enhancements, the system-wide keys are bound to a hardware-based root of trust process devices that support this.The phone needs to have a secure element such as a Trusted Platform Module so that private keys can't be stolen even if the phone is rooted and the attacker has full access to the operating system. Phones that don't have this hardware capability will fall back to software protections for securing credentials.Enhancements to the Android Keystore, a similar resource that also stores credentials, allows users to create keys that can be accessed and used exclusively by a single application. Under version 4.3, "apps can create or store private keys that cannot be seen or used by other apps and can be added to the keystore without any user interaction A third enhancement is Android's ability to create secondary user profiles that implement fine-grained restrictions.

Custom Drawing | Android Developers - 1 views

  • Creating objects ahead of time is an important optimization. Views are redrawn very frequently, and many drawing objects require expensive initialization. Creating drawing objects within your onDraw() method significantly reduces performance and can make your UI appear sluggish.
    • Simon Pan
       
      將物件在初始化時就實例化是很重要的概念,onDraw()的運作速度很快,如困每一個Paint畫圖物件都臨時才在onDraw()產生,將會大幅下降整体程式的流暢效能。
  • If your view doesn't need special control over its size, you only need to override one method: onSizeChanged().
  • is mandatory.

A Visual Guide to Relative Layouts In Android » Mark Lapasa - 0 views

  •  
    " I will walk through the 4 kinds of Relative Layout use cases. 1.Target view position in relation to parenting View Group (i.e. a layout container) 2.Target view alignment in relation to parenting View Group 3.Target view position in relation to another View 4.Target view alignment in relation to another View We'll use Jack and Jill buttons to demonstrate this. The first two categories are in relation to a parent layout (Jack and the parent view group). The last two categories show laying out in relation to another View (i.e. Jack + Jill)"
