How To Set Up a New SDL Android project

Get SDL sources SDL2-2.0.12.tar.gz and extract to a location of your choice

cd /tmp
curl -O https://www.libsdl.org/release/SDL2-2.0.12.tar.gz
tar zxvf SDL2-2.0.12.tar.gz

Set ANDROID_HOME and ANDROID_NDK_HOME. NDK must have a platform/ directory underneath it to be compatible with SDL's androidbuild.sh
```
export ANDROID_HOME=$HOME/Android/Sdk
export ANDROID_NDK_HOME=$ANDROID_HOME/ndk/21.1.6352462/
```

Run androidbuild.sh script (with COPYSOURCE=1):

COPYSOURCE=1 /tmp/SDL2-2.0.12/build-scripts/androidbuild.sh \
  com.orangetide.hellodungeon \
  $HOME/my-prototype/src/hellodungeon.c

Move project to somewhere suitable:

mv /tmp/SDL2-2.0.12/build/com.orangetide.hellodungeon ~/DEVEL/hellodungeon

move include/ to include/SDL2 by shuffling it around

cd ~/DEVEL/hellodungeon
mv app/jni/SDL/include app/jni/SDL/SDL2
mkdir app/jni/SDL/include
mv app/jni/SDL/SDL2 app/jni/SDL/include/

Change to LOCAL_C_INCLUDES := $(LOCAL_PATH)/include/SDL2
```
vim app/jni/SDL/Android.mk
```

Touch up some of the header files for the new include path

cd ~/DEVEL/hellodungeon
sed -i -e 's,../../include,&/SDL2,' $(grep -rl ../include app/jni/SDL/src/events/)

Move your source

cd ~/DEVEL/hellodungeon
mkdir src
mv app/jni/src/*.c src/

Edit LOCAL_SRC_FILES := ../../../src/hellodungeon.c
```
vim app/jni/src/Android.mk
```
Edit target_sources(main PRIVATE ../../../src/hellodungeon.c)
```
vim app/jni/src/CMakeLists.txt
```

Upgrade gradle / Edit to version 7.0.3 or 7.0.2:

cd ~/DEVEL/hellodungeon
vim gradle.properties
vim gradle/wrapper/gradle-wrapper.properties

Fix deprecated gradle features Replace jcenter() with mavenCentral() in both places
```
vim build.gradle
```

Build from command-line

cd ~/DEVEL/hellodungeon
./gradlew assembleDebug
