D2DF-SDL for ANDROID
--------------------

Doom 2D Forever ported to Android 4.1+.

Building
--------

Requirements:
* Android SDK build-tools >= 19.1.0;
* Android SDK platforms >= android-19;
* Android NDK >= r16b;
* Open JDK >= 8;
* FPC >= 3.0.4;
* SDL >= 2.0.7;
* SDL_mixer >= 2.0;
* libenet >= 1.3.13;
* nanoGL.

D2DF uses special version of nanoGL ( https://github.com/DeaDDooMER/nanogl ) with some added functions.
Build all shared libraries using NDK toolchain and put into directory ./ass/lib/armeabi-v7a/.
Also you need to build FPC crosscompiler ( http://wiki.freepascal.org/Android ).

Generate keys:
```
keytool -genkey -validity 10000 \
        -dname "CN=AndroidDebug, O=Android, C=US" \
        -keystore d2df.keystore \
        -storepass android \
        -keypass android \
        -alias androiddebugkey \
        -keyalg RSA \
        -keysize 2048 \
        -v
```

Build D2DF:
```
rm -rf tmp
mkdir -p tmp
cd ../src/game
ppcrossarm \
        -g -gl -dUSE_SDLMIXER -dUSE_NANOGL -O3 \
        -Tandroid \
        -Cparmv7a \
        -Cfvfpv3 \
        -Fi../lib/vampimg \
        -Fi../lib/vampimg/JpegLib \
        -Fi../lib/vampimg/ZLib \
        -Fu../lib/vampimg \
        -Fu../lib/vampimg/JpegLib \
        -Fu../lib/vampimg/ZLib \
        -FU../../android/tmp \
        -FE../../android/ass/lib/armeabi-v7a \
        -Fl../../android/ass/lib/armeabi-v7a \
        -olibDoom2DF.so \
        Doom2DF.lpr
```

Build APK and sign it:
```
rm -rf bin obj gen
mkdir -p bin obj gen
aapt package -f -m -S res -J gen -M AndroidManifest.xml -I ${ANDROID_JAR}
javac -source 1.6 -target 1.6 -d obj -bootclasspath ${ANDROID_JAR} -sourcepath src `find src -name '*.java'`
dx --dex --output=bin/classes.dex obj
aapt package -f \
        -M AndroidManifest.xml \
        -S res \
        -J gen \
        -I ${ANDROID_JAR} \
        -F bin/d2df.unsigned.apk \
        bin ass
jarsigner -sigalg SHA1withRSA -digestalg SHA1 \
        -keystore d2df.keystore \
        -storepass android \
        -keypass android \
        -signedjar bin/d2df.signed.apk \
        bin/d2df.unsigned.apk androiddebugkey
```

Where ${ANDROID_JAR} is path to android.jar file. Typically placed in ~/Android/android-sdk/platforms/android-19/android.jar.
