First, the installation of serial debugging toolsDeveloping Linux drivers cannot be developed directly in Eclipse, like developing Android applications, but can be communicated through the serial port. So we need to install serial debugging tools, here we use the Serial debugging tool is minicom.1, first detect whether the current system supports USB to the serial port, because many notebooks do not support the direct use of the serial line;2, install
Android Development White is embedded in a, embedded products have a lot of, among them, Android development is now the most popular, Android development than the embedded to be more easy, if you want to develop in this area in th
In the fourth chapter, the Android application development environment and the Linux kernel development environment are introduced. Both sets of development environments are prerequisites for Linux development and testing. With two sets of development environments, it's a good place to think about where the Linux drivers should run and what the environment is. This is also the fifth chapter of the content.When a Linux driver that has finished testing
EditText is embedded in ListView, which causes Android keyboard crash. edittext android
Today, I encountered a strange problem. When I clicked EditText on my hammer and Samsung mobile phone, the keyboard flashed and fell back. I did not find this problem on other mobile phones, and I did not find it after searching for a long time, after that, I finally found th
Android source code-embedded clock (3) Proxy/Delegate Application framework Application, android‑clockI. overview when a project requires shell, plug-in, or Hotfix, you can use the Proxy/Delegate Application framework. In normal mode, a program generally has only one Application entry, in the Proxy/Delegate mode, two applications are required. The Application of

The chip is Samsung's 2416, which belongs to ARM9. the cross compiler is a self-transplanted compiler for the helper2416 Development Board. It supports the
My Android advanced tour ------> Android embedded image InsetDrawable usage, androiddrawable
Interview question: Can I specify a background image for a LinearLayout layout filled with the entire Screen to make the background image not full of the screen? Use code to describe the implementation process.
To solve this problem, you can use an Inset image resource to
The fifth chapter constructs the test environment of s3c6410 Development BoardExperienceStart the installation of the Serial debugging tool: minicom OK6410 Development Board with a serial port. Can be connected to the PC via serial cable. The Linux driver sends debug information to the PC at the same time as the output debugging message, so the Linux driver can view debugging information directly on the PC. (Use USB to RS232 serial cable for some note
