1:ubuntu 16.04安裝完
sudo apt-get update
sudo apt-get upgrade

2:

protoc --version

4:
git config --global user.name "jimmy.chen"
git config --global user.email jimmy.chen@hotmail.com.tw

5: 不一定要做, openjdk8也ok
sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt-get update
sudo apt install openjdk-11-jre openjdk-11-jdk

update-alternatives --config java
update-alternatives --config javac

export ANDROID_SDK=/home/zinwell/Android/Sdk
export ANDROID_NDK=/home/zinwell/android-ndk-r18b
export PATH=$PATH:$ANDROID_SDK/platform-tools:$ANDROID_SDK/tools:$ANDROID_NDK


7:
vim build.gradle
minSdkVersion = 25
targetSdkVersion = 28
compileSdkVersion = 28


8: 參考網址

git clone https://code.videolan.org/videolan/vlc-android.git







遇到的問題
1: configure.ac:38: error: required file './config.rpath' not found
到libdsm資料夾下達
autoreconf -fiv -I/home/jimmy/work/vlc-android/vlc/contrib/arm-linux-androideabi/share/aclocal
會發現同樣的問題出現, autoreconfig -I指的是多加一個搜尋路徑,
到arm-linux-androideabi/share/aclocal 做grep config.rpath 會發現是lib-link.m4問題. 但是其變數
ac_aux_dir是出現在gettext source code.

將vlc-android/vlc/contrib/contrib-android-arm-linux-androideabi/gettext/build-aux/config.rpath
copy 到
vlc-android/vlc/contrib/contrib-android-arm-linux-androideabi/libdsm

或者直接在libdsm下產生config.rpath空檔, 因為參考其他的config.rpath似乎是shell, 如果亂寫一通, 一樣可以編譯過關. 所以產生一個空檔案也可以.



這個是因為使用到最新的source code, 如果切到舊的
git branch haha 4eb4b1bf6864711ed62是可以的
git branch 3.2.3  eaf34547


錯誤: Execution failed for task ':medialibrary:compileDevJavaWithJavac'.
echo "org.gradle.java.home=/usr/lib/jvm/java-8-openjdk-amd64" >> ~/.gradle/gradle.properties
這個已經驗證過可以解決
