在Eclipse下导入vlc-android并编译

2022-09-02 12:35:58

在Ubuntu14.04下载好了VLC的源码后，VLC的Eclipse工程存放在"vlc-android"目录

root@dzt-VirtualBox:/home/dzt/android_vlc/android# ls
android-headers-gingerbread compile.sh find_modules.sh NEWS
android-headers-hc configure.sh gcc rename_package.sh
android-headers-ics COPYING gen-env.sh vlc
android-libs dump-libs.sh java-libs vlc-android
assets env.sh Makefile

根据官网的提示
Package in Eclipse [optional]
In Eclipse, create a new Android Project from existing source by importing from the vlc-android path.
Import the three projects from the java-libs folder.
Export unsigned/signed apk.
Note: Building against JDK6 is recommended for optimal compatibility (Set Java Compiler Compliance to 1.6).
在Windows的Eclipse下导入vlc-android工程

还要导入java-libs目录下的几个工程

root@dzt-VirtualBox:/home/dzt/android_vlc/android/java-libs# ls -l
总用量 12
drwxrwxrwx 5 root root 4096  7月 21 15:59 appcompat
drwxrwxrwx 5 root root 4096  7月 21 15:59 SlidingMenu
drwxrwxrwx 5 root root 4096  7月 21 15:59 WheelView

官网推荐我们使用JDK6

vlc-android工程导入Eclipse后的目录结构如下

由于project.properties文件关联了三个工程

# This file is automatically generated by Android Tools.
# Do not modify this file -- YOUR CHANGES WILL BE ERASED!
#
# This file must be checked in Version Control Systems.
#
# To customize properties used by the Ant build system use,
# "ant.properties", and override values to adapt the script to your
# project structure.

# Project target.
target=android-19
android.library.reference.3=../SlidingMenu
android.library.reference.1=../appcompat
android.library.reference.2=../WheelView

所以也要把appcompat 、SlidingMenu 、WheelView这三个工程导入，我的工程都存放在同一目录下

这里只以WheelView为例

导入后的WheelView工程

在VLC工程右键

这时再对VCL工程Clean

对应的APK就生成了

运行后的效果图

相关VLC源码下载：http://download.csdn.net/detail/deng0zhaotai/7661753

这个工程编译出来的apk只适合运行的ARM系列的处理器上，其它MIPS、X86的需要生成不同的库才行

在安装时碰到一个问题，记录下

我是在终端上用命令

sh-4.2# cp mnt/card/VLC.apk /system/app/

报了以上错误，后来查看了：/data/data/org.videolan.vlc/lib 目录，发现是空的，后来才使用以下命令安装就可以了

sh-4.2# pm install -r /mnt/card/VLC.apk /system/app/
        pkg: /mnt/card/VLC.apk
        ver: /system/app/
Success

在Eclipse下导入vlc-android并编译
