Question

我一直在尝试从过去2天为我的应用程序生成安全签名的apk但仍然没有取得任何成功。

我已经检查了StackOverflow的这么多答案并尝试了所有解决方案，但没有任何方法可以帮助我。所以我在这里，如果有人能帮助我，那将是非常感激，并将非常感谢帮助。

以下是我在生成安全签名apk时遇到的错误。

编辑：

我的proguard文件中有一些更改，现在我的错误

  Proguard returned with error code 1. See console

You should check if you need to specify additional program jars.

请帮助我，任何帮助将不胜感激。

Answer 1

我已通过在proguard.cfg文件中添加以下两行来解决了我的问题。

-keep class android.support.v4。** {; }
-dontwarn android.support.v4。 *

Answer 2

使用

-dontwarn android.support.v4.**

另一次尝试：

下载lates proguard（我下载了4.9）并更改了lib文件夹

另一个尝试：

您可以使用标准程序。例如，请参阅here

最近我还遇到了一些问题，并计划深入学习progruard机制。但目前我对此一无所知。但前三个解决方案为我省了几次
