⑴ android-android怎么实现只混淆自己的代码，而不混淆第3方jar包
当项目中有第3方jar包时，怎么实现混淆打包，而不对第3方包混淆
在项目中有第3方包时打包出错日志：

我的proguard.cfg 文件时这样的

-keep class * implements android.os.Parcelable {

}
已经尝试的方案：方案一： 加入-ignorewarnings 可以正常打包了。 能过滤掉警告信息。但是治标不治本，打好的包，在实际运行中用到过的第3方包类库时，均报空指针。方案二：不使用-ignorewarnings 添加-dontwarn java.awt.datatransfer.Transferable.** 警告信息并没有减少，打包会失败。
⑵ Android Studio在真机上运行的APP启动速度特别慢，而通过签名打出的apk安装后app速度却很快怎么回事
Android Studio提供debug和release两种构建类型，默认采用debug类型调试Android项目，debug和release的区别有几个方面：
debug模式的几个特点：
1. 支持断点调试和log信息打印，debuggable属性值为true
2. 使用系统默认的密钥库签署apk文件
3. 没有对apk文件进行代码和资源文件的优化（包括文件压缩、冗余文件删除）
4. 没有对代码进行混淆
release模式需要注意的几个特点：
1. 不支持断点调试，debuggable默认为false
2. 没有压缩类文件代码，minifyEnabled，默认为false
3. 没有压缩资源文件，shrinkResources，默认为false
4. 没有指定自定义签名文件，默认使用系统的密钥库签署apk
真机上直接连接调试，因为没有代码、资源文件进行压缩，同时支持断点调试等原因造成运行缓慢；相反，签名后的apk文件，相对来说比较快，可以深入理解Android Studio构建文件build.gradle配置相关资料
⑶ android 不混淆可以打包吗
可以。
混淆打包流程：
1.在proguard-project.txt文件中添加不需要混淆的类和第三方的jar包
这个是保持自己包中不需要混淆的类，如果有些类调用了jni也不需要混淆，不然会出错。还有如果项目中有其他项目作为library引入，那这些项目的一些类也不能混淆。
这个是保持项目中的第三方jar不混淆
另外加上上面几句话，不然会在控制台中报warning警告
⑷ android studio怎么混淆代码
Android Studio上混淆打包apk方法：
//混淆,新版本是ninifyEnabled不再是runproguard
minifyEnabled true
//加载默认混淆配置文件及自定义混淆 配置
proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard.cfg'
设置minifyEnabled true,就会在打包的时候进行代码混淆处理. 其中proguard-android.txt不用管，在sdk目录里面，主要是配置了proguard.cfg文件。
直接在android studio创建项目不会有这个文件，而是 proguard-rules.pro文件，其实一样的，因为项目是从eclipse迁移过来的，之前在eclipse上混淆是 proguard.cfg文件.
