Link2SD 4.0.11

Source:Bulent Akpinar

Link2SD is an application that makes it easy for Android 1.6+ users with root privileges on their phone to move applications to the SD card.

The idea behind is same with apps2sd scripts, linking applications to SD card's second partition but differs in two ways.

One, instead of linking /data/app folder (that means moving all applications), you can select applications that you want to move.
Two, it's an application which means has a user interface. You can manage your applications with few clicks.

- Create and remove link for apk, dex and lib files of the applications you select
- Automatically link newly installed apps (optional)
- Batch link, unlink, reinstall and uninstall the applications (multi-select mode)
- Uninstall system applications
- List applications, show detailed size information and link status
- Sort and filter applications
- Display available space information of internal storage, SD card and SD card 2nd partition

What you need:
- root permission.
- a second partition on your SD card.

You should have two partitions on SD card and both should be primary.
The first FAT partition is your standard SD card storage. The second partition is used for application files and can be ext2, ext3, ext4 or FAT32.
Some phones lack the ext2, ext3 or ext4 file system support and you may get mount errors like "no such device", "invalid argument". These phones need ext2.ko or ext3.ko modules and even some additional modules to be able to mount. Using FAT32 on the second partition will eleminate such problems, because FAT32 is supported on all phones.

Link2SD does not create the second partition, you need to create it yourself. You can use any partition manager such as Minitool, Paragon, Easeus etc. for this.

How it works:
Link2SD mounts the second partition of your SD card and makes OS mounts it at boot time.

When you select an application and press "Create Link" button Link2SD moves apk file, dalvik-cache (.dex) file and lib files (.so) to SD card's second partition and creates symbolic links in original directories.

Note: On Android 1.6 and 2.1, shortcut and the widget of the app should be re-added to homescreen if you move the apk file.

Can I remove the links and put application files back to phone?
Yes, just click on application that is linked and press "Remove Link" button. Link2SD removes the symbolic links and moves the files to original directories.

What happens if I uninstall a linked application?
If you uninstall a linked application apk, dex and lib files will be automatically deleted from the SD card by Link2SD.

What happens if I update a linked application?
If you update a linked application new apk, dex and lib files will be placed in the internal memory at first and then they will be automatically relinked by Link2SD in the background.
You don't have to manually relink after updating applications.
Note: Since the app is linked again, On Android 1.6 and 2.1, shortcut and the widget of the app should be re-added to homescreen if the apk file is linked.

Some points
- Link2SD detects the apps which are already moved to SD card on Android 2.2+ natively and disables link operations.
- System applications should not be linked to SD card. Link2SD does not allow these applications to be linked.
- When you connect your phone to PC as mass storage, Android unmounts the first FAT partition but the second partition remains mounted. Therefore linked applications are not affected and can be run without problems.
- Link2SD does not move application's private data directory; it moves apk, dex (dalvik-cache) and lib files.
