“Conversion to Dalvik format failed with error 1” — on export only

由 牧云@^-^@ 提交于 2019-12-17 17:38:36
问题 I know this is a repeat question but I've read and tried every solution on this site and I'm still getting the error; also, I'm getting it ONLY when I export my signed apk from Eclipse. I'm able to build and run the unsigned apk. I have: Deleted (and later restored) all libraries from the build path Cleaned and rebuilt all my projects Restarted Eclipse with -clean option Re-create the app project from scratch I know error 1 means I have duplicate symbols but I've checked, clean and rebuilt my

Android多主题调研之Overlay机制

由 China☆狼群 提交于 2019-12-17 17:28:38
【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> Miui的多主题效果非常cool，但应该如何实现呢？有些人可能会想到使用Android系统提供的Overlay机制。但是Overlay机制能否实现多主题呢？通过调研，我的答案是：部分实现。 为何是部分实现？究竟什么是部分实现？ 部分实现指的是Overlay机制可以实现framework资源的多主题替换，但是无法做到App的多主题。Overlay机制本身的目的是为OEM厂商提供一种替换原生系统资源的机制。通过阅读framework的AssetManager.cpp代码(addAssetPath)可以知道，系统在加载framework资源时，会查找是否有framework-res.apk的overlay资源，他是在/vendor/overlay/framework目录下进行查找的。这意味着只要替换/vendor/overlay/framework中的framework-res.apk就能实现framework资源的替换，当然前提需要重启系统。 但是APP资源的Overlay只能在APP编译时完成，一旦编译完成，Overlayed资源也就固定在一个APP中了。当然framework-res.apk也支持这种overlay方式。看AssetManager.cpp代码注释中提到， // add overlay

Android札记【3】——关于Android反编译方面[首届 Google 暑期大学生博客分享大赛]

由 不问归期 提交于 2019-12-17 11:37:10
[首届 Google 暑期大学生博客分享大赛——2010 Android 篇] 写个东西不容易啊！第一次写了一半，上传个文件后，结果网络崩溃了。把我气得......(实践了几次之后发现，在Chrome浏览器下上传图片是会崩溃的，换了搜狗，一切才正常。)其实按照我的札记的顺序，这次本应该写一写关于Android的基本的技术和相关的知识。毕竟这样比较符合逻辑。可是最近学习的时候碰到了关于反编译方面的知识，所以自己留心进行了一系列的实践并做了一下总结，希望能够为大家提供一些帮助。通过反编译，我们可以去看一下别人的一些Android优秀的应用程序是怎样写的，这样也是一种学习的过程（虽然这种学习有点“不道德”。） （ps：对于软件开发人员来说，保护代码安全也是比较重要的因素之一，不过目前来说Google Android平台选择了Java Dalvik VM的方式使其程序很容易破解和被修改，首先APK文件其实就是一个MIME为ZIP的压缩包，我们修改ZIP后缀名方式可以看到内部的文件结构，类似Sun JavaMe的Jar压缩格式一样，不过比较去别的是Android上的二进制代码被编译成为Dex的字节码，所有的Java文件最终会编译进该文件中去，作为托管代码既然虚拟机可以识别，那么我们就可以很轻松的反编译。所有的类调用、涉及到的方法都在里面体现到，至于逻辑的执行可以通过实时调试的方法来查看

Andriod APK体积优化

由 霸气de小男生 提交于 2019-12-17 10:28:47
随着项目的不断迭代，功能越来越多，构建出来的apk文件的大小也会越来越大，这样会导致在移动网络情况下下载时，使用的网络流量会增大，并且apk太大，导致下载的时间也增加，虽然当前每个人的手机的流量都很多，对用户流量影响不大，但是据一些网站统计，安装包越大，用户的转化率是在降低的，所以减少apk的体积，可以让更多的用户愿意去下载和体验产品。所以，对apk体积进行瘦身还是很有必要的。在对apk体积进行瘦身前，最好保证这个apk已经是经过Proguard优化过的。 经过了Proguard对apk进行压缩，优化，混淆后，在去对这个已经进行优化过的apk进行瘦身更有意义。 下面是项目总常用的对apk进行优化的方式： 在app的主module下的gradle文件中做如下配置 buildTypes { release { //开启代码混淆 minifyEnabled true //Zipalign优化 zipAlignEnabled true //移除无用的resource文件 shrinkResources true proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } 使用 shrinkResources 进行移除,配合 //Zipalign优化 使用
