lStar 上的资源链接失败并出现错误

Question

I'm working on a android Native application. My Android builds began to fail without any changes.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':etndoorcontrol:processHesuan_faceDebugResources'.
> Android resource linking failed
  C:\Users\xqf\.gradle\caches\transforms-2\files-2.1\fe7b90aa462d9a2e04dd8216aa450a51\res\values\values.xml:2422:5-2449:25: AAPT: error: resource android:attr/lStar not found.

  error: failed linking references.

Then I tried 2 solutions

//soultion 1.
configurations.all {
    resolutionStrategy {
        // Java language implementation
        force "androidx.core:core:1.6.0"
        // Kotlin
        force "androidx.core:core-ktx:1.6.0"

    }
}

After I add this to app/build.gradle, the app can build correct.but after I install the apk and run.there is a new problem.

After this, I tried the other solution, as below:

ext{
  androidX = 1.6.0
}

but this is not working for me.

Answer 1

axel8888 thank your sir, yes, I have solved this problem. yes, you are right , when I try solution one again

configurations.all {
    resolutionStrategy {
        // Java language implementation
        force "androidx.core:core:1.6.0"
        // Kotlin
        force "androidx.core:core-ktx:1.6.0"

    }
}

and as you the problem is now in

androidx.appcompat:appcompat:1.4.0-alpha

so I checked the gradle dependencies, yes , even I used

androidx.appcompat:appcompat:1.3.1

but my project shows the version is 1.4.0-alpha. here is my solution

    configurations.all {
        resolutionStrategy.eachDependency { details ->
            def requested = details.requested
            
            if (requested.group == "androidx.appcompat") {
                if (requested.name == "appcompat") {
                    details.useVersion "1.3.1"
                }
            }


        }
    }

and it worked, now my project can build and run correctly, thank you, sir!

Answer 2

Obveiously the problem is now in androidx.appcompat:appcompat:1.4.0-alpha. If your UI use Toolbar, you will get the MenuHost not found crash.BUT, evenif I use resolutionStrategy to force 'androidx.appcompat:appcompat:1.3.1', dependency still make it toandroidx.appcompat:appcompat:{strictly 1.4.0-beta01}

It still confuse me a lot.

SOLVED -- someone write a update code for appcompat before... now it can force to 1.3.1 and solve the problem

Answer 3

change implementation 'androidx.appcompat:appcompat:1.4.0' to implementation 'androidx.appcompat:appcompat:1.3.1'

that's it

Answer 4

implementation 'androidx.appcompat:appcompat:1.4.1'

was causing the problem, going back to 1.3.1 worked.

implementation 'androidx.appcompat:appcompat:1.3.1'

ill update once I get an official solution.
