Saunia se poloketi SDL2 e ta'avale ile Android

Talofa uma. O le asō o le a tatou vaʻavaʻai pe faʻapefea ona saunia se poloketi e faʻaaoga ai le sdl2 faletusi e taʻalo ai se taʻaloga i le Android.

Muamua e tatau ona e siiina le Android Studio, faʻapipiʻi ma mea uma e manaʻomia i lenei siosiomaga atinaʻe. Mo se faʻataʻitaʻiga, o loʻo ia te aʻu Kde Neon, ma i luga o lenei faiga o loʻo i ai se faila /etc/environment, o loʻo iai le faila tutusa i ubuntu. E mana'omia ona tu'u iai iina suiga nei.

ANDROID_HOME=/home/username/Android/Sdk
ANDROID_NDK_HOME=/home/username/ndk

E te manaʻomia foʻi le downloadina o le NDK mai le upega tafaʻilagi aloaia, tatala i totonu o lau lisi o fale ma toe faʻaigoaina ile NDK. O le isi mea e te manaʻomia e sii maia le SDL2 faletusi mai le upega tafaʻilagi libsdl.org. E faʻaaoga le sdl2 mo le Android, e taua le aua le faʻapipiʻiina mo le komepiuta, aua o le a le faʻapipiʻiina mo le Android. Ina ia mafai ona tuʻufaʻatasia le poloketi, e tatau ona e fatuina se poloketi i totonu o le Android studio, soʻo se tasi, e talia le laisene, a leai o le SDL2 o le a talosaga mo se laisene pe a fausia.

Ina ia faitau faila i le Android mai aseta, e tatau ona e faʻaogaina le SDL_RWops galuega. O se faʻataʻitaʻiga lea o le faʻaogaina i le code mo le galue i se vaimoa. I lenei tulaga, e le mafai ona matou fa'aogaina le FT_New_Face, ae o le a fa'aoga FT_New_Memory_Face e fa'aoga ai fa'amaumauga ua uma ona faitau.

#ifdef __ANDROID__
        snprintf ( path, 254, "fonts/%s", file );
        SDL_RWops *rw = SDL_RWFromFile(path, "r" );
        char *memory = ( char * ) calloc ( rw->hidden.androidio.size, 1 );
        SDL_RWread(rw, memory, 1, rw->hidden.androidio.size );

        FT_New_Memory_Face(*this->ft_library, ( const FT_Byte  * )memory, rw->hidden.androidio.size, 0, &this;->face );
        SDL_RWclose(rw);
        free ( memory );
#else
        snprintf ( path, 254, "%s/fonts/%s", DEFAULT_ASSETS, file );
        if ( access ( path, F_OK ) ) {
                fprintf ( stderr, "not found font: %sn", path );
                exit ( EXIT_FAILURE );
        }
        struct stat st;
        stat ( path, &st; );
        FILE *rw = fopen ( path, "r" );
        char *memory = ( char * ) calloc ( st.st_size, 1 );
        fread ( memory, 1, st.st_size, rw );

        FT_New_Memory_Face ( *this->ft_library, ( const FT_Byte * ) memory, st.st_size, 0, &this;->face );
        fclose ( rw );
        free ( memory );
#endif

Na ou faia foi se faila faila e faʻafesoʻotaʻi ulutala SDL2. NO_SDL_GLEXT e mana'omia mo le tu'ufa'atasiga ina ia manuia ile Android.

#ifdef __ANDROID__
#include "SDL.h"
#include "SDL_video.h"
#include "SDL_events.h"
#define NO_SDL_GLEXT 
#include "SDL_opengl.h"
#include "SDL_opengles2.h"
#else
#include <SDL2/SDL.h>
#include <SDL2/SDL_video.h>
#include <SDL2/SDL_opengl.h>
#include <SDL2/SDL_opengles2.h>
#endif

O lea ua sauni le poloketi, ua sauni le au paʻu mo Opengl Es 3.0. Ole taimi nei e tatau ona tatou fatuina se Android-poloketi. Ina ia faia lenei mea, tatala le SDL2 archive. Alu ile build-scripts. Ma tatou faia faapea.

./androidbuild.sh com.xverizex.test main.cpp

O le a aliali mai le savali o loʻo mulimuli mai.

To build and install to a device for testing, run the following:
cd /home/cf/programs/SDL2-2.0.10/build/com.xverizex.test
./gradlew installDebug

Alu ile com.xverizex.test. Alu ile com.xverizex.test/app/jni/src. Matou te kopiina la matou galuega faatino. Ma matou suia le faila Android.mk, i loʻu tulaga e pei o lenei.

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := main

SDL_PATH := ../SDL
FREETYPE_PATH := ../Freetype2

LOCAL_C_INCLUDES := $(LOCAL_PATH)/$(SDL_PATH)/include $(LOCAL_PATH)/$(FREETYPE_PATH)/include

# Add your application source files here...
LOCAL_SRC_FILES := ./engine/lang.cpp ./engine/actor.cpp ./engine/sprite.cpp ./engine/shaders.cpp ./engine/box.cpp ./engine/menubox.cpp ./engine/load_manager.cpp ./engine/main.cpp ./engine/font.cpp ./engine/model.cpp ./engine/button.cpp ./theme.cpp ./level_manager.cpp ./menu/menu.cpp

LOCAL_SHARED_LIBRARIES := SDL2 Freetype2

LOCAL_LDLIBS := -lGLESv1_CM -lGLESv2 -llog 

include $(BUILD_SHARED_LIBRARY)

E pei ona e matauina, ou te aofia ai foi le Freetype2 faletusi. Na ou mauaina se mea ua saunia i luga o le github mo le Android, ae e leʻi aoga, e tatau ona ou suia se mea. Matou te faia foʻi se faʻatonuga app/src/main/assets. Matou te tuʻuina a matou punaoa i totonu (fonts, sprites, 3D models).

Sei o tatou fetuutuunai le Freetype2 mo le Android. Sii mai la'u github fesoʻotaʻiga, ma kopi le Freetype2 directory i le app/jni/ directory. Ua sauni mea uma. Fa'atino nei le fa'atonuga ./gradlew installDebug i le com.xverizex.test. Ina ia mafai ona faʻaopoopo lenei taʻaloga i le Android, e tatau ona faʻaogaina le debugging i le Android. Ina ia faia lenei mea, e tatau ona e alu i tulaga, alu i le "System", alu i le "About tablet" ma kiliki le "Fausia numera" filifiliga e tusa ma le ono taimi. Ona toe foʻi lea ma faʻaalia le filifiliga mo tagata atiae. Alu i totonu ma liliu i luga, liliu foi i luga o le "USB Debugging" filifiliga. O lea la e tatau ona e maua se ki mo le laulau. Ina ia faia lenei mea, faʻapipiʻi le polokalame adb. Matou te faʻalauiloa le atigi adb i totonu o le faʻamafanafanaga, ma faʻaalia se ki i le laulau e tatau ona talia. O le mea lena, o lea e mafai ona sii mai taaloga i lau laulau.
