Build an android + SDK + ndk + eclipse + cygwin + ant in the compilation environment of powervr insider SDK/OpenGL ES 2.x SDK/Android JNI

 

 

 

 

Background:

On the imagination website, I studied a powervr SDK for OpenGL ES 2.0.

Http://www.imgtec.com/powervr/insider/sdkdownloads/index.asp#GLES2

3D engine development can be performed across different platforms. Currently, popular Android and IOS

Register and download the SDK on the Android platform and study the two-day environment.

 

Applicable:

It is suitable for Android users who use ndk to develop OpenGL ES-related 3D applications in C ++.

 

Purpose

I have encountered many problems during the construction process. I am only providing document backup, and the readers can use it for their own purposes and will not communicate with each other.

Use android in Eclipse:

1. Install JDK

Jdk-6u25-windows-i586.exe
(Not detected after the first installation)

 

2. Install the android SDK (JDK required)

Installer_r11-windows.exe

Installation directory on
E:/Android-SDK

 

3. Start the SDK Manager SDK
Manager.exe (Android SDK must be installed)

Download and install android
SDK platform 2.3.3 api10 and Android SDK platform-tools R5

 

4. Install Android ndk

Android-ndk-r5-windows.zip

Extract
E:/Android-ndk

 

5. Install cygwin_setup

Select the default download and Installation

And additional download and Installation
Make GCC package under devlep

Install to E:/cygwin

6. Install ant, which must be later than version 1.8

Apache-ant-1.8.2-bin.zip

Decompress the package to E:/apacheant.

6.1 install ipvs with built-in ant, but it seems that the version is only 1.7, So I press 6 to directly install

Eclipse-java-helios-SR2-win32.zip

Decompress the package to E:/eclipse.

6.2 install ADT, eclips required

ADT-10.0.1.zip

Decompress the package to the eclipse installation path. E:/eclipse merge folder

6.3 configure ADT

Open eclipse and set the SDK path in Windows> preferences> androidy.

Click Apply to check the available Android versions under the SDK. Steps 1, 2, 4 are required.

7. set E:/cygwin. bat

Optional

Home
-- Home in cygwin installation path

Ndk
-- Ndk installation path

SDK
-- SDK installation path

Demo
-- Test the program path. I tested the powervr Android SDK.

Ant
-- Ant installation path

"

@ Echo off

 

E:

Chdir E:/cygwin/bin

 

Set Home =/cygdrive/e/cygwin/home/

Set ndk =/cygdrive/e/Android-ndk

Set SDK =/cygdrive/e/Android-SDK

Set demo =/cygdrive/f/data collection/powervr/sdk_android/demos

Set ant =/cygdrive/e/apacheant

 

Bash -- login-I

"

 

8. Run the demo experiment of cygwin.

1) test make and GCC. If the following command is correct, make and GCC are installed successfully.

Make
-V

Gcc
-V

2) view variables, reference variables, and set variables

Printenv
Home

$ Ndk
(Add the symbol "$" before referencing ")

Export
Path =.: $ ndk (path is a series of paths connected)

3) switch the directory to CD dir

CD
$ Demo/navigation3d/ogles2/build/android

Dir
View files in the current directory

 

4) run the android update project setting command: Android
Update Project-P

Android commands cannot be found
-Bash: Android: Command not found

Commands not referenced or environment variables not set

$ SDK/tools/Android. bat
(Note: There is no direct Android command. I only find the Android. BAT file)

Update
The-p parameter is missing in the project.

$ SDK/tools/Android. bat
Update Project-P./(./is under the current directory, and CD is required to the current directory)

5) Use ndk to compile the C ++ code into the so file ndk-build, provided that the CD is under the compilation directory.

The problem that the ndk-build command cannot be found
-Bash: ndk-Build: Command not found

$ Ndk/ndk-build
Clean

$ Ndk/ndk-build

6) Use ant to package the so and java files into APK, ant debug

The ant command cannot be found.

$ ANT/bin/ant
Debug or use eclipse to right-click build. xml and run as with ant.

The problem that cannot be found by com. Android. Ant. setuptask: taskdef
Class com. Android. Ant. setuptask cannot be found

The premise is that the current Android project has updated the properties and generated local. properties, which sets the SDK directory.

For example, my local. properties file is:
SDK. dir = E: // Android-SDK

Or you have used the command to update: Android
Update Project-P

The ant version is too low.

The
Android ant-based build system requires ant 1.8.0 or later. Current version is
1.7.1

Install a later version of ant and run it in cygwin.
$ ANT/bin/ant debug

 

 

7) install Android 2.3 and include OpenGL
The APK file is tested on the elasticsearch 2.0 hardware-accelerated mobile phone (Samsung i9000) and runs normally.
