Manually enable app2sd in Android 2.2

<Doctype HTML public-wcdtd XHTML stricten httpwwwworgtrxhtmldtdxhtml-strictdtd>

Because app2sd of Android 2.2 is not fully enabled by default, only a few pieces of software can be installed on the SD card, so to install the software on the SD card, you need to manually activate it.

There are two methods:
The first is to use ADB on the computer. For example, the PC assistant can install the program on SD.
The second method is to directly operate on the mobile phone and use a Super Terminal to input commands.

The second method is described below.

The premise for this solution is that your mobile phone is already root. To determine whether the program is root, check whether the program "authorization management" exists in the program menu. If yes, It is root.

First, install "terminal emulator" on your mobile phone"
After the installation is complete, open the software, first enter Su, and press Enter. To obtain the highest permissions. After you press enter, the authorization dialog box is displayed. Click allow.

Enter PM setinstalllocation 2 and pay attention to space and case. Press enter after the input is complete. OK. app2sd is enabled successfully.

In this case, you can go to program management and check that all the software you have installed can be moved to the SD card. Subsequent installation is also installed on the SD card by default. However, you must note that some software must be installed on your mobile phone,

For example, for desktop plug-ins and input methods, if the input method is installed on the SD card, the input method will change to the system default value after each restart and needs to be selected again. Inconvenient.

PS: unexpected situations also occur. For example, when you enter Su at the beginning, the authorization prompt is not displayed, but the character "Permission denied" is returned. This is yours.

Rom root has a problem and the authorization is denied. It is recommended that you change the Rom, because not only this software, many software will be unable to be authorized. In addition, you cannot root this ROM again (I personally test it), because the Rom has been root, although it is a failed root. So change the Rom.

In addition, if you want to change to the default installation on your mobile phone, enter PM setinstalllocation 0.
Okay. 2.2 enabling app2sd is so easy.
