我正在尝试测试 LibGDX 开发，但我在尝试让最基本的应用程序在我的 Android 手机上运行时遇到错误，因为我的 keystore 或它的使用方式存在问题，而且我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keypass，有时使用命令行，有时通过Android Studio的“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
经过一番努力，我最终意识到我必须将我的 keystore 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，填写一个Name，“Key Alias”，“Key Password”，“Store File”和“Store密码”，确保它们与我创建的最新 key 密码相匹配。
创建签名后，我选择它，然后单击“确定”，然后确实在我的 gradle 文件中看到它已添加到我的 gradle android 模块中
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，或者运行它并单击通过插入的 Android 手机运行它的选项时，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，但我一直小心翼翼地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， keystore 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:

最佳答案
好吧，我发现了问题，我只是错过了一个额外的步骤，我不得不在“项目属性”->“模块:android”下转到“构建类型”，然后选择 keystore ，我以为我已经选择了，通过在签名下突出显示它。
