How to fix "Android resource linking failed" error in Android Studio?

Question

I just started learning and working with "Android Studio" software and editing a project. It took too long to figure out how to work with that. I just fixed many errors and now i know many thing about errors but one thing happened to me and it's making me crazy! I can't fix this error and don't know what is wrong with that. This is Error:

File which addressed in error text is out of my project folder and sure it is a Cached folder for gradle! Tried to clear caches, rebuilding project, deleting code lines from files, etc. nothing works! Hope someone can help me about this.

And my "build.gradle" file's codes is:

apply plugin: 'com.android.application'

Answer 1

I faced a similar issue which I solved by downgrading the google services dependency.

My gradle had:

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.1"

    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
}

dependencies {
    implementation 'com.google.android.material:material:1.5.0-rc01'
}

to

android {
        compileSdkVersion 26
        buildToolsVersion "26.0.1"
    
        defaultConfig {
            minSdkVersion 15
            targetSdkVersion 26
            versionCode 1
            versionName "1.0"
    }

dependencies {
    implementation 'com.google.android.material:material:1.2.0'
}

This resolved the issue for me. You could give it a try

Answer 2

The problem is here:

defaultConfig {
    targetSdkVersion 21
}

The attribute android.R.attr.contextPopupMenuStyle was not added until API level 24, so you must target at least 24 for the Material Components library to access that attribute.

Looks like there is missing styles in your project. If there is another project you are studying and copying from, check its res/values/styles.xml file and compare with yours. Otherwise you need to create these styles.
