更改安卓手机默认软件安装路径方法（Change Android mobile phone default software installation path method） 更改安卓手机默认软件安装路径方法(Change Android mobile phone default software installation path method) Google Android mobile phone system default only to install the software on mobile phone memory, so that the already small mobile phone memory is difficult. If you are a mobile phone software madman, love to try all kinds of new and interesting software, with less memory space to the mobile phone, the software has been installed under the pain * *. Are you still tangled between installation and uninstall? Follow Me! We work together to expand Android system expansion, "robot" can also be potbellied, replacing the menace from the rear of insufficient storage space. Tips: memory is divided into random access memory (RAM) and read-only memory (ROM) two. Mobile phone ROM is equivalent to PC on the hard disk storage for mobile phone operating system and software, also called FLASH ROM, mobile phone determines the size of storage space. Mobile phone RAM is equivalent to PC of memory, it determines the running speed of the mobile phone. To put the elephant in the refrigerator is divided into three steps, and the Android system of the software installed to the SD card, more simple, the two step is enough: A memory card, partition First we need to partition the SD card mobile phone, a FAT32 partition and a Ext3 partition, FAT32 partition for normal store photos, music and video data, and Linux format Ext3 partition is used to install the software partition expansion. The author of the 2G SD card as an example, the FAT32 partition 1.35GB, Ext3 partition 494MB. Download and install Acronis Disk Director Suite software. The mobile phone SD card into the card reader is connected to the computer, and then run the Acronis DiskDirector Suite software. 1.FAT32 partition. Find the representative of SD card partition, right-click and select "delete" command, delete the existing partition. When a "unassigned" partition, right-click and select "create partition", in the pop-up dialog box, select the file system: FAT32, create a "partition", set the partition size 1.35GB, click the OK button. 2.Ext3 partition. In the rest of the 494MB partition, right click and select "create partition", in the pop-up dialog box, select the file system: Ext3, create a "partition", set the partition size 494MB, click the OK button. 3. confirm the partition. The partition set is complete, the software only records the partition operation, and no real partitions on the SD card. Click on the software toolbar in the "submit" button and confirm the implementation of partition operation, "operation completed successfully" partition success. Two, the software will move to SD card The memory card is completed we only need to partition the system default software installation directory /data/app transfer to SD card Ext3 partition, and then through the LN command to establish soft link, make the system to install the software automatically to the SD card, save the memory space of the mobile phone. The memory card loaded back to the mobile phone, restart, the system identifies the Ext3 partition. Run the super terminal in the mobile phone, in order to enter the following command to verify whether the system identification Ext3 partition: Su (Senior authorization will be prompted, select "always agree") Busybox DF - H If the system has successfully identified the Ext3 partition /dev/block/mmcblk0p2 display list information. Then enter the following commands: /data/app directory will be transferred to the SD card Ext3 partition: CP - a /data/app /system/sd/ (the /data/app directory to /system/sd/) RM - R /data/app (delete the /data/app directory) Ln - s /system/sd/app /data/app (a soft link) Reboot (mobile phone restart) After the restart, all software installed on the mobile phone is transferred to the SD card, look at the space available on your mobile phone is not increased. After installing the software is installed directly to the SD card, do not worry about the problem of insufficient space, and it also has a good, refresh ROM, previously installed software has not been cleared, but also saved in the SD card, enter the following commands can be easily recovered, not again installed, very convenient and practical. Su (Senior authority) CD /data (in the /data directory) CP - a app /system/sd/app (copy the contents of app to the /system/sd/app directory) RM - R app (delete the app directory) Ln - s /system/sd/app /data/app (a soft link) Reboot (restart) The expansion effect of experience: Refresh after ROM without installing any software, mobile phone space available for the 87MB, install some software, available space decreased to 73MB. The software directory transfer to SD card, available space into 80MB. Some of the "Torch" may have doubts, why not return to 87MB? This is because we will only move to the software on the SD card, and software cache data will still occupy the mobile phone memory, so the mobile phone memory or will drop. Of course, the software can also move the cached data to the SD card, but this will slow down the running speed of software, so we do not recommend the use of. Matters needing attention: 1. mobile software to the SD card, the original part of the desktop plug-in will not display properly, delete, re join the desktop. A part of the 2.SD card Ext3 partition can be regarded as the mobile phone hardware, remove the SD card after the installation of the software will not run. Insert the SD card, restart the mobile phone can be used normally.
