Xamarin Forms Error APT1000: Found tag id where item is expected (Android)

Question

I'm trying to use Google Ads with the package MarcTron.AdMob.

After I install it, I need to install some dependencies and update some packages, as it said me to do:

Xamarin.AndroidX.Browser
Xamarin.Google.Android.Material
Xamarin.AndroidX.Lifecycle.LiveData
Xamarin.AndroidX.Legacy.Support.V4

But after I install/update all this dependencies, I compile again and get the error:

2>myproject.Android\obj\Debug\100\lp\111\jl\res\values\values.xml(1482): error APT1000: Attribute "android:translationX" has already been defined
2>myproject.Android\obj\Debug\100\lp\111\jl\res\values\values.xml(1486): error APT1000: Attribute "android:translationY" has already been defined
2>myproject.Android\obj\Debug\100\lp\111\jl\res\values\values.xml(1489): error APT1000: Attribute "android:translationZ" has already been defined
2>myproject.Android\obj\Debug\100\lp\83\jl\res\values\values.xml(4): error APT1000: Found tag id where item is expected
2>myproject.Android\obj\Debug\100\lp\82\jl\res\values\values.xml(4): error APT1000: Found tag id where item is expected
2>myproject.Android\obj\Debug\100\lp\76\jl\res\values\values.xml(4): error APT1000: Found tag id where item is expected

What I already did:

• Cleaned the project and compiled it again;
• Follow this solution here;
• Removed the whitespaces of colors.xml and styles.xml inside my Resources (it was another solution that I saw);
• Change the API level (28 - 9.0 and 29 - 10.0).
• Downgrade the packages.

Nothing worked.

I tried to using Xamarin.Firebase.Ads instead of MarcTron.AdsMob but the same error appears to me.

What is this error and how can I solve it? I really need to put ads on the application and I can't continue the project with this error.

Answer 1

In my case checking "Use incremental Android packaging system (aapt2)" in Android options in project Properties fixed the issue.

Answer 2

The solution was creating a blank project and copy/paste all my classes, folders, resources...

I really wanted to solve this because in several sites has the same question that I did, so it was good to help the community. For now, the solution was that.

EDIT:

All right ladies and gentlemen, I found the BIZARRE error of this: Just my folder that I have the folder of my project has an accent: "ó". Just that.
