Cause: failed to decrypt safe co

Android studio签名打包时报错：

错误内容：

Cause: failed to decrypt safe contents entry: javax.crypto.BadPaddingException: 
Given final block not properly padded. Such issues can arise if a bad key
 is used during decryption.

错误原因：

在app build.gradle文件里面签名配置项中jks签名文件密码配置错误。

解决方法：

如果有正确密码，则改正。否则重新生成一个签名文件即可。
