1 HAL is a set of libraries built on Linux drivers that are not part of the Linux kernel but belong to the application layer on the Linux kernel layer. Its purpose is to protect "private property" and to avoid direct access to Linux Drivers by the application . 2 There are two ways to use Linux drivers in an Andro

Some problems encountered during the learning of PHP, but not all of them can be solved smoothly. In the PDO abstraction layer, rowCount () is used (); when the data can be queried normally, the returned result is 0. I searched the internet for a day without a specific explanation and solution. Many friends asked, but

InitSDK first parses the parameters: In the UCUser's initSDK method, we get the parameters required by the current SDK through the U8SDK. getInstance (). getSDKParams () method. So what are these parameters. These parameters are the parameters that need to be passed in w
