Android installation

Software requirement for Android

1)      First check the system requirement for install the Android sdk for hardware and software supported or not.

2)      Also install the JDK 5.0 or 6.0  and Eclipse v 3.4 or 3.5.

Hardware requirements

The Android SDK requires disk storage for all of the components that you choose to install. The table below provides a rough idea of the disk-space requirements to expect, based on the components that you plan to use.

Component type	Approximate size	Comments
SDK Tools	50 MB	Required.
Android platform (each)	150 MB	At least one platform is required.
SDK Add-on (each)	100 MB	Optional.
USB Driver for Windows	10 MB	Optional. For Windows only.
Samples (per platform)	10M	Optional.
Offline documentation	250 MB	Optional.

Note that the disk-space requirements above are in addition to those of the Eclipse IDE, JDK, or other prerequisite tools that you may need to install on your development computer.

Supported Operating Systems

·        Windows XP (32-bit) or Vista (32- or 64-bit)

·        Mac OS X 10.5.8 or later (x86 only)

·        Linux (tested on Linux Ubuntu Hardy Heron)

64-bit distributions must be capable of running 32-bit applications. For information about how to add support for 32-bit applications, see the Ubuntu Linux installation notes.

Note: If any case you have not Sdk starter package please download and install the sdk starter package

How-To Use Eclipse To Develop Android Applications

In order to begin development on your Android applications you will first need to create a new Android project and then configure a launch configuration.

Configuration For Eclipse

In order to be able to run and debug your own Eclipse applications you must first create a launch configuration. Simply, a launch config is used to specify which project to launch, which activity to start and the specific emulation options to use.
To create a launch configuration for the application, please see the following steps:
1. Select Run > Open Run Dialog… or Run > Open Debug Dialog… as appropriate.
2. In the project type list on the left, right-click Android Application and select New.
3. Enter a name for your configuration.
4. On the Android tab, browse for the project and Activity to start.
5. On the Emulator tab, set the desired screen and network properties, as well as any other emulator startup options.
6. You can set additional options on the Common tab as desired.
7. Press Apply to save the launch configuration, or press Run or Debug
Installing the Android SDK.
To add /tools:

Linux

1. Edit the ~/.bash_profile or ~/.bashrc files looking for a line that sets the PATH variable.
2. Add the full path location to your $SDK_ROOT/tools location for the PATH variable.
3. If no PATH line exists you can add the line by typing the following:
4. export PATH=${PATH}:<path to your $SDK_ROOT/tools>

Mac OS X

1. In the home directory locate the .bash_profile and locating the PATH variable add the location to your $SDK_ROOT/tools folder.
