In layout XML files, the red exclamation mark is displayed left of
@drawable references. Almost all
drawables have this mark:
The content of
shape_detail_btn_border.xml is as below. It is a group of shapes and does not have any broken image resource:
<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> <solid android:color="@android:color/white"/> <corners android:radius="5dp"/> <stroke android:width="1dp" android:color="@color/bapul_color_d5d5d5"/> </shape>
I hover the mouse on the mark and nothing shows up. what does this mean?
Note that the Android Studio version is 1.4 (AI-141.2288178), currently the most recent version. And, there's no problem to build and run the app at all.
