获取 "Cause: failed to decrypt safe contents entry: javax.crypto.BadPaddingException: Given final block not properly padded"

Question

我正在尝试测试 LibGDX 开发，但在我 android phone 上尝试将最基本的应用程序设置为运行时出现错误，因为我的密钥库或它的使用方式存在一些问题，我不确定到底是什么问题。

在更详细地描述问题和我尝试过的方法之前，我将首先描述一些关于我的环境的事情：

我正在使用：

 - `Android Studio 3.1.4,`              with
 - `Gradle 4.6`                         inside of it, my os is
 - `Linux Mint 18.1 (Serena)            (which is based on...
 -  `Ubuntu 16.04`,                     my kernel is 
 -  `Linux 4.4.0-53-generic`.

为了解决这个问题，我多次生成新的密钥密码s, sometimes using the command line, and sometimes through Android Studio's "Build" -> "Generate Signed APK" -> "Create New..."选项。

我生成的最新一个是使用“Build" -> "Generate Signed SPK" -> "Create New..." 选项

然后经过一番努力，我最终意识到我必须将我的密钥库添加到我的 gradle 文件中，这是我做错的第一件事，我最终偶然发现了 "File" -> "Project Structure" -> "android" -> "Signing" 选项，点击绿色“+”号并填写名称，"Key Alias"、"Key Password"、"Store File" 和 "Store Password"，确保它们与最新的 keypass 匹配我创造了。

创建签名后，我选择了它，然后单击 "OK"，然后确实在我的 gradle 文件中看到它，它已添加到我的 gradle android模块

我将 gradle 文件与我的应用程序重新同步，然后清理了我的应用程序。

但是，当我尝试重建我的应用程序时，或者运行它并通过我插入的 Android Phone 单击运行宁它的选项，我收到错误消息：

Cause: failed to decrypt safe contents entry: javax.crypto.BadPaddingException: Given final block not properly padded

我做了一些研究试图解决这个问题，一种可能是我使用了错误的密码，但我一直小心确保我使用了正确的密码，但并没有解决这个问题.

我在做一些研究后发现的另一种可能性是，密钥库的密码有一定的规则，我认为不使用特殊字符是其中之一，所以我确保我遵循了那个规则。

但我也知道有 2 个不同的密码，也许它们有不同的规则，但我不确定这是我的问题，我认为是其他原因。

非常感谢您帮助解决此签名问题，非常感谢。

编辑：我要添加一些我的 gradle 文件内容：

Answer 1

好吧，我发现了问题，我只是少了一个额外的步骤，我不得不在 "Project Properties"->Modules: android 和 [=15= 下进行 "Build Types" ] 密钥库，我以为我已经 selected，通过在签名下突出显示它。

Answer 2

我的解决方案：

1.- 在 Android Studio 4.0.1 中：构建/生成签名构建/APK 生成New Key Store 没有的情况下，把所有参数都放上去。

2.- 一旦你已经有了密钥库，就可以生成 APK 的签名版本，使用与点 1

相同的密码和别名

3.- 我选择调试并启用检查：V2（完整 APK 签名）并按下按钮完成

4.- 最后，在文件/项目结构中，转到模块/签名配置并再次对参数进行数字化并确定。

按照 Android 工作室中的这些步骤，我可以毫无问题地将我的应用程序部署到我的 AVD 中。
