There are two ways to replace launcher on Android: one is to input the launcher when the IMG is burned to the device, or try to replace the launcher. Test the second type. You want to modify and replace the following Android launcher, but the directory/system/app where the laucher is located is read-only. You need to set it to RW through remount first.

Because of the wide range of systems involved, it is impossible to clarify the logs of all UNIX-class systems, but most of them are similar. Below I will only use the common SunOS RedHat for introduction. for other systems, see related information. UNIX system log files are usually stored in the "/var/log and/var/adm" directory. Generally, you can view syslog. conf to check the log configuration, for example, CAT/etc/syslog. conf. Under/var/log and/var/adm of SunOS, there is also a link with/us

After the system is started, it is found that the same USB device has been attached multiple times, causing problems in the File Manager applications. The process of attaching a USB device is in Android/system/vold/volume. cpp and is handled by the volume: mountudiskvol function. You can solve this problem by checking whether the device has been mounted before mounting: Bool isusbdevicemounted (const char * path) {char device [256]; char mount_pa

So I don't need to go to the Linux system every time I have to mount it again! Of course you can! Then go straight to the /etc/fstab and fix it! But before we start, let's talk about some of the limitations of the system mount:Th

Yesterday, we introduced how to manually execute commands to mount a file system. If you often need to mount some file systems, how can I enable the system to automatically mount them at startup? The following two methods are described: Method 1. Place the mount command in/etc/rc. d/rc. local. This is a method, but it is not recommended to do so, because our system has a unified planning solution, so the second method is recommended. Method 2. Modify the configuration file/etc/
