如何找到问题 Android SDK 3.0 Error:(9, 5) error: resource android:attr/colorError not found

如何在我制作时找到此错误的问题我收到此错误消息:错误:(9, 5) 错误:找不到资源 android:attr/colorError

How to find issue to this error when I did a make I have got this error message : Error:(9, 5) error: resource android:attr/colorError not found

奇怪的是我有 2 个 build.gradle 文件:这是我的 build.gradle (Project:Projectname) 文件:

Thing strange I've 2 build.gradle files : Here my build.gradle (Project:Projectname) File :

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

这里是我的 build.gradle (Module:app) 文件:

Here my build.gradle (Module:app) File :

apply plugin: 'com.android.application'
android {
    compileSdkVersion 22
    defaultConfig {
        applicationId "org.acme.nfcedit"
        minSdkVersion 22
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    productFlavors {
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}
