_ write_to_log_kernel.Look at the implementation of _ write_to_kernel (), which is basically a write operation:static int __write_to_log_kernel(log_id_t log_id, struct iovec *vec, size_t nr){ ssize_t ret; int log_fd; if (/*(int)log_id >= 0 */ (int)log_id To sum up, the println_native () operation is to open the device file (if it has not been opened) and then write data. But how to write it depends on the implementation of the logger driver

function. If the word_count_read function returns N, you can read n characters from the Buf. Of course, if n is 0, no characters can be read. If n is less than 0, an error occurs (n is the error code ). The Buf in the word_count_write function indicates the data written by the user space application. There is a "_ User" macro before the Buf parameter, indicating that the Buf's memory zone is located in the

Apache-based The software for the source code of the LICENCE2.0 protocol must also be open source. Since HAL is part of Android, it doesn't have to be open source.The next step is to use the LED driver porting to demonstrate the Linux driver that supports HAL, so let's get an initial look at its steps.* Write a service called Hal Die Missing1. Because JNI uses a lot of C + + code, LedHalService.cpp cannot be changed to LEDHALSERVICE.C.The leds_hat.h

Android UI operations are not thread-safe, and only the main thread can operate the UI. At the same time, the main thread has a certain time limit on UI operations (up to 5 seconds ). To perform some time-consuming operations (such as downloading and opening large files), Android provides some column mechanisms. The articles in the "android basics 02-thread secur

This design features differences in media stream processing when decoding different types of files at the underlying layer, and provides control functions for external camera devices, the player is finally implemented on the Android platform [1.2.
