How to debug Android * x86 applications and the tools to be used

1. Introduction As we all know, Android * developers are often referred to as designers, programmers, and so on, and often referred to as fault repair engineers. Errors in the Code cannot be avoided. Therefore, whether or not you cause errors at the beginning or not, it is important to understand debugging tools and how to quickly and effectively track and resolve errors. Now, Android Developers must master effective debugging skills. This article provides a simple tutorial on debugging tools f

Openwrt x86 compilation Diary

Label: style blog Io color OS AR for SP Background Some time ago, I saw the c1037u multi-network port version. I liked it very much. I replaced the 4530r and found that there were fewer people playing openwrt x86. I wrote a diary for later use. Please point out any errors. 0. Configure the compiling environment Linux 1.

The performance gap between ARM and X86 is not comparable, which may be several thousand times larger.

Transferred from CNBETA, original address: http://www.cnbeta.com/articles/167883.htmarmand x86are not comparable. The performance gap may be several thousand times higher. Here we will not care about the details. Let's just talk about why ARM and X86 are not comparable. To clarify this question, first of all, we need to understand what architecture is. Many people have mentioned that the architecture is different, but what does the architecture mean?

[Graphic] Android-X86 + VirtualBox to build a high performance Android development environment

I don't know how many Android developers have a problem with the tragic performance of Android virtual machines, anyway, my opinion is: That's too much speed! Why are Android virtual machines much slower than iOS and WP7 's virtual machine? For the following reasons: 1. The Android simulator simulates the ARM architecture (Arm-eabi), while the target architecture for iOS and WP7 simulators is x86, and the App running in iOS emulator is compiled to

Android2.2 source code compilation Environment: -- ubuntu10.04 (x86) + android2.2 + jdk1.6 Note: The official statement is that JDK 1.5 must be used in a 32-bit system. This is because Android API docs is compiled.Requires 1.5. To use JDK, you must use a 64-bit system-why is it 64. If you want to succeed at a time, you 'd better use jdk1.5 as officially said (of course you use 64-bitLinux is more convenient). In this case, there is basically no big pr
