硕士学位论文基于 Android 的绘图软件开发 摘要Android 是 Google 于 2025 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进展，越来越多的人开始使用 Android 并作为娱乐和工作平台。与此同时随着现代绘图软件的进展，这使得通过数码手段复制自然绘画体验成为可能，传统意义上的纸上作图已经失去优势。但是，目前 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，本文主要讨论基于 Android 移动平台的绘图软件开发。本文所做的讨论工作主要在以下几个方面：1. 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 绘图软件的开发。2. 将开源视频编码库 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。3. 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。4. 实现了 Android 绘图软件的开发。关键词： Android, MyPaint, FFMPEG, NDK, 绘图软件AbstractAndroid is the opensource mobile operation system which release by Google in 2025. 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 didn't 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 MyPaint's brush engine in Java language and transplant it in Android platform.We will use this engine in our painting software develop...
