Compile the JNI method for the hardware abstraction layer (HAL) module of Android in Ubuntu to provide the Java access hardware service interface (Lao Luo study note 4), androidjni In the last two articles, we introduced how to write drivers for Android hardware, including how to implement kernel drivers in Linux kernel space and Hardware Abstraction Layer interfaces in user space. The purpose of both is to provide a hardware access interface to the p

Add the hardware abstraction layer (HAL) module on Ubuntu to access the Linux Kernel Driver (Lao Luo study note 3) and ubuntuandroid In the overview and learning plan of the hardware abstraction layer (HAL) of Android, we briefly introduce how to write a driver for the hardware in Android. To put it simply,Hardware drivers are distributed in the Linux kernel and in the hardware abstraction layer of the user space.. Next, compile the Linux kernel drive

interfaces, based on delegation, and based on HTTP + XML, represent three styles from constraints to protocols, from strict to flexible. Of course, there are more methods, but here we only list these three methods as the representative. The dynamic and static interfaces must be controlled in a specific sense, and the interface is too rigid. The HTTP + XML method is completely based on the runtime protocol, and you need to perform a lot of checks on your own; the advantage of delegation is that

For non-static external member variables (such as: Context, View) that need to be used in static internal classes, you can use weak references in static inner classes to refer to variables of external classes to avoid memory leaks4. For an internal class object with a longer life cycle than the activity, and the internal class uses the member variables of the outer cl
