Hear ye! Hear Ye! CyanogenMod needs our help

This image has no alt text

Ever since the day the Ice Cream Sandwich source code was released, most of us have eagerly been waiting for CM9. The huge changes in code meant that the task of the team was already an extremely difficult one. Unfortunately, they face another obstacle: funding.

Cyanogen posted earlier today the need for some cash to help maintain and distribute the source code.

As you may know, our nightly builds have recently been sporadic at best. The reason behind this is that previously, we had access to a large compute cluster to perform these builds. This was really great, and gave us all the power we needed to pump out 50+ builds a day. Unfortunately, we no longer have access to this cluster, and have not for quite some time. With CM9 coming up, and CM7.2 ready to go out the door, we are now in quite a bit of a mess.

So come on, people. Let’s contribute in whatever way we can, even if it means not ordering fries the next time we eat out, or canceling that gym subscription that we never use. The PayPal link is at the bottom of the CyanogenMod website.

Pro Android Apps Performance Optimization

Today’s Android apps developers are often running into the need to refine, improve and optimize their apps performances. As more complex apps can be created, it is even more important for developers to deal with this critical issue.

Android allows developers to write apps using Java, C or a combination of both with the Android SDK and the Android NDK.Pro Android Apps Performance Optimization reveals how to fine-tune your Android apps, making them more stable and faster. In this book, you’ll learn the following:

  • How to optimize your Java code with the SDK, but also how to write and optimize native code using advanced features of the Android NDK such as using ARM single instruction multiple data (SIMD) instructions (in C or assembly)
  • How to use multithreading in your application, how make best use of memory and how to maximize battery life
  • How to use to some OpenGL optimizations and to Renderscript, a new feature in Android 3.0 (Honeycomb) and expanded in Android 4.0 (Ice Cream Sandwich).

After reading and using this book, you’ll be a better coder and your apps will be better-coded. Better-performing apps mean better reviews and eventually, more money for you as the app developer or your indie shop.

What you’ll learn

  • How to optimize your applications in Java
  • How to optimize your applications using the NDK
  • How to best use memory to maximize performance
  • How to maximize battery life
  • How and when to use multi-threading
  • How to benchmark and profile your code
  • How to optimize OpenGL code and use Renderscript

Who this book is for

Android developers already familiar with Java and Android SDK, who want to go one step further and learn how to maximize performance.

Table of Contents

  1. Optimizing Java code
  2. Getting started with the Android NDK
  3. Using advanced NDK features
  4. Using memory efficiently
  5. Multithreading and synchronization
  6. Benchmarking and profiling your application
