Android Development Environment setup and ndk installation in Linux)

I am also a newcomer to Linux. It takes about half a year to get Linux, and I am also a newcomer to the android team.

Since I recently used centos 5.5 every day, I chose centos5.5 as my development environment.

I used to dive in linuxsir for the first time. I wrote down my post carefully. At the same time, as my study notes, I will send my learning achievements.

As a newbie, if anything is wrong, I hope you will not give me any further advice and take care of it ~

Directory

1. Establish the environment

1.1 JDK Installation

1.2 install eclipse

1.3 ADT Installation

1.4 Android SDK Installation

1.5 install Android ndk

Content

1.1 JDK Installation

No centos built-in Java environment, download the latest version of Oracle Java, for the http://www.oracle.com
/Technetwork/ja...sp-136632.html

Directly download and select Platform
In Linux download, I did not register, directly click continue to enter the next page, select the type of the package you want to download, I select

Jdk-6u21-linux-i586-rpm.bin network speed faster, then it will be finished.

Modify executable permissions after the download is complete # chmod + x jdk-6u21-linux-i586-rpm.bin

Then execute it

#./Jdk-6u1-linux-i586-rpm.bin

Some options may appear in the process, direct Yes

After installation, the environment variable program is installed under/usr/Java by default.

Note: In Windows, multiple values are separated by semicolons (;), but in Linux, the colon is used:

# Vim/etc/profile

Add the following content at the end of the file

Export java_home =/usr/Java/jdk1.6.0 _ 21

Export java_bin =/usr/Java/jdk1.6.0 _ 21/bin

Export Path = $ path: $ java_home/bin

Export classpath =.: $ java_home/lib/dt. jar: $ java_home/lib/tools. Jar

Export java_home java_bin path classpath

Check the Java version later.

# Java-version

Java (TM) se Runtime Environment (build 1.6.0 _ 21-b06)

Java hotspot (TM) server VM (build 17.0-f8, mixed mode)

After the Java environment is configured, install ide again. Eclipse is recommended for Google.

1.2 install eclipse

I am also a newbie, and of course everything is up to date. Eclipse also downloads the latest version of eclipse (Helios version ). Download eclipse

Http://www.eclipse.org/downloads/

Eclipse IDE for Java developers, 98 MB Linux 32 bit

People who have experience in Java Development basically know that eclipse is a green version and can be used after decompression. Double-click the eclipse file in the eclipse folder.
Run Eclipse IDE for Java dvelopers. You are familiar with it. Set up the workspace. You are welcome to turn off the interface and go to the development environment.

I put eclipse under/home/Android/, and I will put everything I need under it later.

1.3 ADT Installation

ADT version:

ADT 0.9.7 (May 2010) Android Development Tool

(1) Use the eclipse upgrade manager to install ADT:

1. Start eclipse and go to help> install new software.

2. In the available software dialog box, click Add ....

3. In the Add site dialog box, enter a name (for example, "android plugin") in the Name field"
Enter URL in the domain: https://dl-ssl.google.com/android/eclipse/

4. Note: If you have any questions, you can change HTTPS to HTTP. Click OK.

5. Return to the available software interface and you should see "Developer Tools ". Select checkbox. Click
Next, accept the license agreement, and then click Finish.

6. Restart eclipse.

(2) manually install ADT and download the ADT. ADT 0.9.7

Http://dl.google.com/android/ADT-0.9.7.zip

After the download is complete, decompress the package and copy the corresponding file to the corresponding eclipse directory ..

You can also point the help> install new software. installation address to the ADT folder after decompression, as shown in the preceding figure.

1.4 Android SDK Installation

Download the android SDK core package

For linux version http://dl-ssl.google.com/android/rep..._r01-linux.zip

You need to know that this zip package is not a complete package. Android
The software package is in the form of "components". You can select components as needed. The preceding ZIP file contains only one component management tool and one basic tool component.

.

Next we will configure the ADT installed above

Configure the ADT in eclipse to point it to the android SDK.

1. Select eclipse WINDOW> preferences...

2. Select android

3. Click Browse... to find the android SDK
Directory. For example, my directory:/home/Android/android-sdk-linux_86

4. Click Apply and OK.

The development environment has been set up with the baseline, but we still need to upgrade and download some things and complete the SDK. There are many update packages, including the doc documentation, sample code for samples, and
SDK file. The whole process will automatically download and install:

1. Run eclipse and select Window> Android SDK and AVD manager.

2. Select installed packages in the left-side navigation pane.

3. Click Update all.

The choose packages to install dialog appears. Select accept all and click Install

About 1.4gb capacity. If there is no problem with the internet, it will definitely be done in one night.

4. Create an AVD

To enable the Android Application to run on the simulator, you must create an AVD.

(1) In eclipse. Choose Windows> Android SDK and AVD Manager

(2) Click virtual devices on the left panel, and then click New on the right.

(3) Fill in the name and select the target API. the SD card is of any size and skin is selected. Currently, hardware retains the default value.

(4) Click Create AVD to create AVD.

After reading some materials, we have developed all of them based on 1.6. You only need to compile the version later. I have not tried it ~

1.5 install Android ndk

Some Java developers have abandoned the Procedural language like C. Compared with open-source Android projects, the C world has accumulated many open-source projects that can be reused (including many famous games such
Quake, doom), which involves a large number of mathematical operations in execution efficiency can also be considered by C.

To develop C/C ++ programs, you may need to integrate eclipse CDT.

CDT, which is the C/C ++ environment of eclipse. Online installation address
Http://download.eclipse.org/tools/cdt/releases/galileo.

You can also manually install it after the download is complete, as I described above.

1. Start eclipse and go to help> install new software.2 at available software
In the dialog box, click Add ....

3. Add and decompress the folder address-> select local and click OK. Then select the required content for installation.

After running an ndk example project, I found that CDT is not necessary and may be used later, or integrated with the QT development environment.

Ndk: http://dl.google.com/android/ndk/and...-linux-x86.zip

The installation of ndk is very simple, that is, to extract the downloaded package to the specified location. After decompression, we usually need to configure the environment variable. Here we put the configuration of the Environment Variable together for configuration.

Unzipping location:/home/Android/android-NDK-r4b

# Vim/etc/profile

# Set ndk env

Ndkroot =/home/Android/android-ndk-r4b

Export Path = $ ndkroot: $ path

When compiling ndk, you also need to configure some, with hellojin. Very classic Hello ~ Create an android project and import it to the existing source.

Open the hello-JNI project properties, select builder, select program, and click OK.

The configuration is as follows: ndk_builder, location, and working directory.

/Usr/bin/bash and/usr/bin

Arguments must be consistent with your project directory.

My arguments is: -- login-c "CD
/Home/Android/android-ndk-r4b/samples/Hello-JNI &&
$ Ndkroot/ndk-build"

After completion, you can run.
