硕士学位论文 基于Android的绘图软件开发 摘要 Android是Google于2007年发布的一款开源手机操作系统，由于Android最近几年的软件和硬件高速发展，越来越多的人开始使用Android并Android平台并没有很多具有很好绘图效果的绘画工具应用。考虑到Android绘图软件的开发价值和很好的应用前景，本文主要研究基于Android移动平台的绘图软件开发。 本文所做的研究工作主要在以下几个方面： 将开源绘图软件MyPaint的笔刷引擎以Java语言重写并移植到Android平台，并以此引擎进行本文的Android。FFMPEG成功移植到Android平台，利用此库进行用户绘画过程的录制，并生成MP4格式的视频。 分析了Android底层开发的原理和方法，探讨了一种利用JNI机制进行Android底层c/c++开发技术。 实现了Android绘图软件的开发。 关键词： Android, MyPaint, FFMPEG, NDK, 绘图软件 Abstract Android is the opensource mobile operation system which release by Google in 2007. In recent years, more and more people begin to use Android devices as entertainment and working platform, because of the high speed development of Android software and hardware. Meanwhile, with the development of modern drawing software, the traditional drawing has lost its advantage, and made it possible copying nature painting experience through digital method. But the Android platform didnt have a lot of application which have good effect of paint. This paper mainly discuss about Android painting software development, considering of the value and good prospect for Android painting software. In this paper, the main research work done in the following aspects: 1. Rewrite the MyPaints brush engine in Java language and transplant it in Android platform.We will use this engine in our painting software development. 2. Transplant the FFMPEG to Android platform succeed and using it for recording users painting process, at last it will generate video file which is MP4 format. 3. Analysis the principle and method of low level component development in Android and discusses one of c/c + + development technology by using JNI method. 4. Of the painting software for Android development is realized. Key Words：Android，MyPaint, FFMPEG, NDK, Painting Software 摘要 i Abstract ii 目录 III 图目录 V 第1章 绪论 1 1.1 课题背景及意义 1 1.1.1 课题背景 1 1.1.2 课题意义 1 1.2 论文主要内容 2 1.3 本章小结 2 第2章 Android平台整体结构分析 3 2.1 Android系统架构 3 2.2 Android应用组件 6 2.2.1 AndroidManifest.xml 6 2.2
