我是android的新手，我只是推出了我的第一个应用程序。我遇到了以下错误，我很难理解代码中的哪些地方出错了代码中的哪一行崩溃了（我习惯了Log。 d（，＆＃34;＆＃34;））在此先感谢任何帮助或解释。

2 个答案:

答案 0 :(得分：1)

这与您的日志无关。您的某个用户发生了崩溃，并通过Play Developper控制台进行了报告。

在您的代码的某个时刻，您正在尝试将ColorDrawable对象转换为RoundRectDrawableWithShadow，从而导致崩溃。

以下几行为您提供了发生这种情况的地方：

  

在android.support.v7.widget.CardViewEclairMr1.getMinWidth（CardViewEclairMr1.java:150）

如果它不属于您自己的类，您可能会检查您是否没有错误地使用支持库，因为崩溃似乎来自使用android.support.v7.widget包。 / p>

当您使用proguard缩小，混淆或优化时，也会发生这种错误。

答案 1 :(得分：1)

两件事：

一：

将myHolder.itemView.setBackgroundColor(Color.SOME_COLOR);更改为((CardView)myHolder.itemView).setCardBackgroundColor(Color.SOME_COLOR);，无论您在哪里使用

二：

我认为您在将应用程序上传到Play商店之前已经对其进行了测试。这意味着错误与发布apk有关。通常，当我们构建一个签名的apk时，ProGuard将尝试缩小包括外部库的代码。那个原因有时会崩溃。

因此，您可以做的是从ProGuard缩小过程中排除所有外部库。找到模块中名为proguard-android.txt的文件。并添加以下内容，

-keep class org.** { *; }
-keep interface org.** { *; }
-keep enum org.** { *; }

这将排除包名称以org开头的所有类/接口/枚举。对所有外部库执行相同操作。再次构建签名发布apk。确保使用签名的apk测试应用程序，而不是调试版。
