Android 2.2 – How to install apps directly in SD card

by André under Android, Configurations, Tutorial

ome Android smartphones have low capacity internal memory and not allow you to install many apps.

At Android 2.2 there is a possibility migrate the apps to SD card after instalation, but some applications not allow to do this.

Looking for a fix to solve this problem in my Motorola Droid, I found a way to install apps directly in SD card, like show in Mundo Zoom, and not need root.

Download ZIP file from Android SDK and extract. Browse to folder “android-sdk-windows\platform-tools“.

Set your Android to debug mode. Don’t you know? “Settings” > “Applications” > “Development” and enable “USB debugging” option.

Connect your smartphone in USB and enable “Charge Only” on USB Connection Management.

Click in Start Menu, Run. Type “cmd” e press Enter to open command prompt.

With command prompt and Windows Explorer opened, click and drag file “adb.exe” to prompt window, after, insert a space and type “shell”. Press Enter.

The “$” simbol and cursor should appear. Now type “pm setInstallLocation 2” and press Enter

This command sets partition “2″ (SD Card) as default to install applications.

Done! That`s all you need for apps to be installed directly in your SD card

Why to use File.separator and File.pathSeparator

by André under Development, Java, Quick tips

Java programmers knows about methods quoted in title, but many doesn’t care with them.

These methods are useful for programmer that do not knows wich characters represents file separator and path separator at OS that supports your application.

Linux/Unix, the methods File.separator and File.pathSeparator returns “/” and “.”, while in Windows, these methods returns “\” (or “\\” – escape) and “;”.

In recent case, the code below threw exception FileNotFoundException running over Linux, but not running over Windows:

String appPath = ctx.getRealPath();
String filePath = appPath + "\\" + "WEB-INF/classes/my/application/packages/";

File file = new File(filePath, "report.pdf");
OutputStream out = new FileOutputStream(file);
...

Worked in both systems after to replace “\\” by File.separator in line 2:

String appPath = ctx.getRealPath();
String filePath = appPath + File.separator + "WEB-INF/classes/my/application/packages/";

File file = new File(filePath, "report.pdf");
OutputStream out = new FileOutputStream(file);
...

Utilization of these methods, besides a good practice, is very usefull when same version of an application is running over differents operacional systems.
