This is placeholder for documentation about Fedora used as Android development box

Abstract

This page should provide "how-to" document about using Fedora Linux for developing applications for Android platform.

This document will cover requirements, steps how to go from source code till final application and how to use Android Emulator for testing of application.

Target Fedora version

F-12 and higher

Requirements

  • Eclipse IDE (3.5 and higher is needed because of ADT plugin dependency on Equinox P2)
yum install eclipse-jdt
  • Android SDK

Download SDK from page

http://developer.android.com
  • ADT plugin for Eclipse
    • Start Eclipse, then select Help > Install new software...
    • Click on the Available Software site hyperlink.
    • In Available software sites dialog, click Add....
    • In the Add Site dialog that appears, enter a name for the remote site (for example "Eclipse Update") in the "Name" field. In the Location field, enter this URL:
http://download.eclipse.org/releases/galileo/

This will add dependency which are required for ADT plugin.

    • Again click on Add button and enter a name for the another remote site (for example, "Android Plugin") in the "Name" field. In the "Location" field, enter this URL:
https://dl-ssl.google.com/android/eclipse/ 

Note: If you have trouble acquiring the plugin, you can try using "http" in the URL, instead of "https" (https is preferred for security reasons).Click OK.

    • Back in the Available Software view, you should now in see in drop down list "Android Plugin", select it and in box below see "Developer Tools" added to the list. Select the checkbox next to Developer Tools, which will automatically select the nested tools Android DDMS and Android Development Tools. Click Next.
    • In the resulting Install Details dialog, the Android DDMS and Android Development Tools features are listed. Click Next to read and accept the license agreement and install any dependencies, then click Finish.
    • Restart Eclipse.

Install Android SDK

  • download android-sdk_r05-linux_86.tgz from http://developer.android.com/sdk/index.html
  • unpack it in your home directory into ~/AndroidSDK
  • add into path environment variable ~/AndroidSDK in .bash_profile file in your home directory.
    For example:
PATH=$PATH:$HOME/AndroidSDK
export PATH
  • logout and login back to apply path change

Android Emulator

This is important
If you have 64-bit systems, you will need to polute your system with 32bit packages, because Android SDK is 32bit

32 bit packages


# yum install glibc.i686
# yum install glibc-devel.i686
# yum install libstdc++.i686
# yum install zlib-devel.i686
# yum install ncurses-devel.i686
# yum install libX11-devel.i686
# yum install libXrender.i686
# yum install libXrandr.i686

AVD device


  1. cd into the ~/AndroidSDK directory and run tools/android to configure and create your first Android Virtual Device.
  2. Go to "Available Packages", select components for just those versions of Android you want to work with. For example:
    • SDK Platform Android 2.1
    • Documentation for Android SDK
  3. Click on "Install selected", then click on "accept all" and confirm with clicking on "Install". This will start component installation, when it will be done, click on close. When this will be done, we could proceed with creation of AVD device itself.
  4. Go to "Virtual Devices", Click on "New", this will open screen where you need to specify SD card size (I will use 62MiB), name of device (I will use "android_dev1", target (Android 2.1, if you want to develop for different target, you need to go to step 2 and install SDK platform for different version).
  5. Now click on "Create AVD" which will create Android Virtual Device.

Running Emulator


Now we have created Android Virtual Device and we should start it, however, due to issues in AndroidSDK with sound, we will need to run it from command line

./emulator -noaudio -avd android_dev1

And this will start emulator for us.

Hello Fedora


Configure Android in Eclipse


  1. Go to Window -> Preferences, click on Android and set SDK location to directory. (for example /home/user/AndroidSDK) and click on Apply.
  2. Click on apply to reload available targets
  3. choose target android SDK
  4. click on OK

Create a New Android Project


After you've created an AVD, the next step is to start a new Android project in Eclipse.

  1. From Eclipse, select File > New > Project. If the ADT Plugin for Eclipse has been successfully installed, the resulting dialog should have a folder labeled "Android" which should contain "Android Project". (After you create one or more Android projects, an entry for "Android XML File" will also be available.)
  2. Select "Android Project" and click Next.
  3. On next screen type Project Name ("HelloFedora"), Application name (Hello, Fedora), package name (com.example.hellofedora) which represent your namespace and name of activity in "Create Activity" box (HelloFedora). Choose target (if you have multiple targets) and click on "Finish". This will create project for you.
  4. open HelloFedora.java and paste there example code from Hello Fedora Code section.
  5. click on windows -> preferences. In new window, open Android -> Launch and into "Options" text box insert "-noaudio"
  6. open separate console, cd ~/AndroidSDK/tools and execute ./emulator -noaudio @android_dev1 to start emulator. Wait for start of emulator (it could take several minutes)
  7. in eclipse, click on "run" and it will deploy application into Android Virtual Device.

Hello Fedora Code

package com.example.hellofedora;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class HelloFedora extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        TextView tv = new TextView(this);
        tv.setText("Hello, Android Developer\n Thank you, for using Fedora Linux");
        setContentView(tv);

    }
}
