com.android.builder.internal.aapt.v2.Aapt2Exception: Android resource compilation failed

Question

I have a old android project, Now I decided to run it, After migration to androidX and add some upgrade in libraries I got these errors when I am trying to run it:

* Exception is:

This is gradle.properies:

android.enableJetifier=true

android.useAndroidX=true

What is the problem?

Does the file cited in the error exist? If so, what does line 5159 contain? — CommonsWare

Sorry, I was referring to /mnt/Media/usb/mobile-android/client14/build/intermediates/incremental/mergeDebugResources/merged.dir/values/values.xml. The failures are complaining about several lines deep in this file, such as line 5159. I was interested in what those lines look like. — CommonsWare

there is ` <item name="does_not_have" type="id">ندارد.</item>` @CommonsWare — Cyrus the Great

This is about my ids.xml <?xml version="1.0" encoding="utf-8"?> <resources> <item name="wimax_number" type="id">شماره وایمکس</item> <item name="not_entered" type="id">وارد نشده</item> <item name="does_not_have" type="id">ندارد.</item> <item name="has" type="id">دارد.</item> <item name="wait" type="id">منتظر بمانید</item> </resources> — Cyrus the Great

An ID resource does not have a body. Are those really supposed to be ID resources, or are they supposed to be string resources? — CommonsWare

ID resources are not supposed to have text in the XML node, the way that yours do.

My best guess is that the build tools were more forgiving about this back when you worked on this project originally. Now, they are enforcing the rules more.

So, if you remove the text from those failing <id> elements, you should be in better shape.
