Android Resource Linking Failed - Android Studio

Question

I build my project and there is no error but when i try to run it on my device it throws this error.

C:\Users\FAISAL NAZIR\.gradle\caches\transforms-2\files-2.1\eaf17b24d60dc773c7680b20ac141638\material-1.1.0\res\layout\mtrl_calendar_month_navigation.xml:32: AAPT: error: 'textEnd' is incompatible with attribute iconGravity (attr) flags [start=1, textStart=2] [weak].

This is the xml file in which it is showing error, the worst thing is, this file is auto-generated so i cannot edit or manipulate it.

Answer 1

Tried to upgrade to 1.2.1-rc1 the error is still there. It works after downgrading the nuget to 1.0.0.1

Answer 2

error: 'textEnd' is incompatible with attribute iconGravity

Use com.google.android.material:material:1.1.0 for Material Components

because it was given support from 1.1.0-alpha06, if you are using below 1.1.0-alpha06, it will not work. see releases

Answer 3

It looks like it a confliction between packages. In my case, I had to downgrade the following packages to the following versions:

• Xamarin.AndroidX.Core : 1.6.0.3 (currently latest is 1.6.0.4)
• Xamarin.AndroidX.Activity : 1.3.1.2 (currently latest is 1.3.1.3)

Clean your project and remove bin/obj folders to get fresh build, and try to build. If it fails, just try building again (without cleaning). The above is currently solution in my case after hours of headache. I wish it helps a lot of developer facing similar issue.

If you still have issues, do the following: In case you have Xamarin.Android.Support.V4 installed, uninstall it and use the latest versions of following packages instead:

• Xamarin.Android.Support.Compat
• Xamarin.Android.Support.Core.UI
• Xamarin.Android.Support.Core.Utils
• Xamarin.Android.Support.CustomTabs
• Xamarin.Android.Support.Design
• Xamarin.Android.Support.Fragment
• Xamarin.AndroidX.Legacy.Support.Core.UI

Use AndroidX instead of Support library in your code.

The above is what I use in my project which might help you solve confliction issues for many of us.
