Android Variants, Hacks, Tricks and Resources – AnDevCon II

The second Android developer Conference (AnDevCon II) took place about 10 days ago. Karim Yaghmour of OperSys published the presentation slides he used during his two Android presentations. The first presentation was Embedded Android Workshop, the same presentation he did at Android Open 2011. The second presentation “Android Variants, Hacks, Tricks and Resources” slides can be found below. Those 48 slides cover the following: AOSP’s limitations: Rigid, closed development model, excludes many things… Tearing AOSP apart Forks: Cyanogenmod: After-market handset firmware with custom launcher and lots of tweaks and mods… Replicant: 100% open souce with FDroid marketplace. MIUI: Closed source with UI enhancements. Ports: RIM Playbook:  OMAP4 Tablet based on AOSP. Bluestacks: Android on Windows 7. Alien Dalvik: Android SDK + Meego SDK integration. Mods: XDA Developers. Melding with “Classic” Linux Stack: Rationale: Lots of available stacks in Linux, Android does not provide everything. Road blocks: File system, Bionic C […]

WebP Image Format Could Replace JPEG, PNG and GIF

In September 2010, Google announced the WebP image format with lossy compression.  Since last month, WebP can also support animation, ICC profile, XMP metadata and tiling. Today, it announced lossless compression and transparency support. WebP could be used as an alternative to JPEG, with 25–34% better compression compared to JPEG images at equivalent SSIM index as well as PNG as it now supports lossless compression and transparency – also known as alpha channel – in both the lossless and lossy modes. On average, Google got a 45% reduction in size when starting with PNGs found on the web, and a 28% reduction in size compared to PNGs that are re-compressed with pngcrush and pngout. Photos typically encoded as JPEG can be encoded in WebP lossy mode to achieve smaller file size. Icons and graphics can be encoded better in WebP lossless mode than in PNG. WebP lossy with alpha can […]
