[Original] 0 Basic learning SDL Development porting SDL2.0 to Android

In the [Original]SDL development tutorial we know how to use SDL for development under the PC, is it possible to use the same on Android? The answer is yes.

Here we are porting SDL to Android, which is based on the latest version of SDL, and is compiled in eclipse.

Development environment: Ubuntu 14.04 64-bit, Eclipse + CDT + adt,ndk

first, to the official website download http://www.libsdl.org/hg.php Download 2.0 of the source code can also be through the HG to clone the latest source code

Ii. compiling the SDL

Go to the downloaded file sdl2-2.0.3 import android-project into Eclipse, go to the Jni folder, create a new SDL file, and SDL2-2.0.3\SRC, Sdl2-2.0.3\include, The Sdl2-2.0.3\android.mk file is copied to the android-project\jni\sdl\. The contents of the Android-project\jni\sdl\android.mk file are as follows:

Configure the NDK in Eclipse, Eclipse->window->prefreneces->android->ndk.

Third, if the direct compilation will prompt the following error

file or directory  

View EGL support is above the 2.3 version, so we need to add platform support, so in the JNI directory modify the Application.mk file to specify the build platform:

if you're using the STL in your project with for more information# App_stl:= stlport_static app_abi:= Armeabi armeabi-v7ax86app_platform:= android-9

Iv. executing ctrl+b in eclipse will compile the libsdl2.so and compile the process as follows:

We'll be able to use SDL to develop it later.
