问题六:
Android Studio 2.3打包后,安装到手机失败。
标红的地方已经提到,选择 V2 签名,则无效,我这里也得到了相应的提示了。也就是说,V2 签名之后,当前 apk 是不能做任何操作了。
后面我也做了一下尝试,除了 单独勾选 V2 签名无效之外,其他的单选 V1 , 或者 V1 , V2同时勾选,签名之后的包都能正常发放了。

Android studio2.3之前是可以直接安装到设备上的,安装方式之一就是在docs命令行里用adb install <apk绝对路径>命令去安装到连接到PC上的Android设备。
问题五:
Warning:Exception while processing task java.io.IOException: Can't write [G:\JingYeProject\JingYeApplication\JingYeLogistics\build\intermediates\transforms\proguard\91\release\jars\3\1f\main.jar] (Can't read [C:\Users\lenovo\.gradle\caches\modules-2\files-2.1\com.umeng.analytics\analytics\6.1.1\4bff754fc05336940a8cb348e455c01515b5d883\analytics-6.1.1.jar(;;;;;;**.class)] (Duplicate zip entry [analytics-6.1.1.jar:com/umeng/analytics/pro/cq$1.class]))

compile 'com.umeng.analytics:analytics:latest.integration'
和umeng的两个jar包,采用其中一种形式就可以。
问题四(已解决):
Warning:Exception while processing task java.io.IOException: The same input jar [G:\JingYeProject\JingYeApplication\JingYeLogistics\libs\umeng-analytics-v6.1.1.jar] is specified twice.
compile files('libs/umeng-analytics-v6.1.1.jar')
需要在build.gradle文件中添加上上面导入jar包的语句。
Exception while processing task java.io.IOException: The same input jar is specified twice.

解决方法如下:
打开 proguard.cfg
在所有的-libraryjars 前插入 # 成 #-libraryjars xxxx.jar
原因分析
原因是build.gradle文件配置了dependencies { compile fileTree(include: '*.jar', dir: 'libs')}里面已经添加过jar包,混淆文件proguard.cfg里面又加了句-libraryjars libs/***.jar,将-libraryjars libs/***.jar 前面用#号注释或者直接删掉即可。
sdk 通过 proguard 混淆代码时默认已经将 lib目录中的 jar 都已经添加到打包脚本中,所以不需要再次手动添加。

(2)问:警告io的,将okio避免混淆就可以了
