Android studio打包apk遇到的问题

问题一、Android studio 生成apk文件时的 key store path 的问题

使用Android studio生成apk文件时，Key store path 是密钥库文件地址的意思，新手菜鸟会想，我怎么知道他在哪里，其实他的地址是你来决定的。如下图，你选择一个文件夹后，填写file name，然后点击ok就生成了

用户密码：

app->build.gradle-->signingConfigs {config

问题二、Errors while building APK. You can find the errors in the 'Messages' view.解决办法

当你出现这种情况，有两种解决办法：（都是在build.gradle中修改）

一

android{
    lintOptions {
        checkReleaseBuilds false
        abortOnError false
    }
}

二

 aaptOptions.cruncherEnabled = false
 aaptOptions.useNewCruncher = false

问题三：A failure occurred while executing com.android.build.gradle.tasks.MergeResources$FileGenerationWorkA

报错内容如下：

Error:There were multiple failures while executing work items

Error:Execution failed for task ':app:mergeDebugResources'.There were multiple failures while executing work items
A failure occurred while executing com.android.build.gradle.tasks.MergeResources$FileGenerationWorkAction

这个bug解决起来也比较简单，在你的app的build.gradle的defaultConfig中添加如下的代码就可以了：

defaultConfig{  
   vectorDrawables.useSupportLibrary = true  
}  

添加完 vectorDrawables.useSupportLibrary = true这行代码之后，gradle一下就可以了。
