Android Studio 堆栈跟踪错误

Question

我最近刚开始接触 Android 开发，我需要帮助找出导致错误的原因。我昨天正在处理我的项目并且它运行良好，直到我关闭它并在第二天打开它收到渲染问题从而阻止我看到预览屏幕。我的堆栈跟踪如下:

还有我在项目中处理过的文件:

activity_sign_in.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

            android:textColor="#306e50"
            android:textStyle="bold" />

    </LinearLayout>

</LinearLayout>

如果这里需要任何其他文件的代码是我的项目菜单:

Answer 1

            android:textAppearance="@color/colorAccent"

这两行是我在 xml 中的问题。一定是设置错误的值。以为我会把这篇文章留给其他人。
