Android Platforms

Each platform release includes system images

that support a specific processor architecture,

such as ARM EABI, Intel x86 or MIPS. Platform

releases also include a system image that contains

Google APIs. The SDK Manager lists available

platform system images under each platform

version header, for example:

ARM EABI v7a System Image

Intel x86 Atom System Image

MIPS System Image

Google APIs

Publishing an App to google play

It is important that you have an existing

account in google play

You must have a credit card and is willing to

pay 25$ for registration

https://play.google.com/apps/publish/signup/

Publishing an App to google play All applications must be signed. The

system will not install an application on

an emulator or a device if it is not signed.

To test and debug your application, the

build tools sign your application with a

special debug key that is created by the

Android SDK build tools.

When you are ready to release your

application for end-users, you must sign it

with a suitable private key. You cannot

publish an application that is signed with

the debug key generated by the SDK tools.

You can use self-signed certificates to sign

your applications. No certificate authority

is needed.

The system tests a signer certificate's

expiration date only at install time. If an

application's signer certificate expires

after the application is installed, the

application will continue to function

normally.

You can use standard tools — Keytool and

Jarsigner — to generate keys and sign your

application .apk files.

After you sign your application for

release, we recommend that you use the

zipalign tool to optimize the final APK

package.

Publishing an App to google playRequirements

1. A completed Android application

project in Eclipse or an already

created “.apk” file

2. An Internet connection

3. A credit/debit card to pay for

Google Developer license

4. At least two screenshots of the

app, stored on your computer

5. Establishing Your Android File

Plugin Installation – Android

SDK Manager

The Android SDK separates tools, platforms, and other

components into packages you can download using the

SDK Manager.

For example, when the SDK Tools are updated

or a new version of the Android platform is released,

you can use the SDK Manager to quickly download them to

your environment.

Android Virtual Device Manager

AVD

An Android Virtual Device (AVD) is

an emulator configuration that lets

you model an actual device by

defining hardware and software

options to be emulated by the

Android Emulator.

Android Debug Bridge Android Debug Bridge (adb) is a versatile command line

tool that lets you communicate with an emulator instance

or connected Android-powered device. It is a client-server

program that includes three components:

A client, which runs on your development machine. You can

invoke a client from a shell by issuing an adb command.

Other Android tools such as the ADT plugin and DDMS also

create adb clients.

A server, which runs as a background process on your

development machine. The server manages communication

between the client and the adb daemon running on an

emulator or device.

A daemon, which runs as a background process on each

emulator or device instance.

An activity is a single,

focused thing that

the user can do, it

represents a single

screen in your app

IntentA.k.a. intention to do something, enable an application to transfer from one activity to another

Fragments

A Fragment represents a

behaviour or a portion of user

interface in an Activity
