我该如何解决这个错误？资源链接失败

Question

我正在尝试在手机上运行我的新应用，但遇到了这个错误：

Android 资源链接失败 C:\Users\HP PAVILION G6- 1310\Miok\app\build\intermediates\merged_manifests\debug\AndroidManifest.xml:20： 错误：在中发现意外元素 .

我在 stackoverflow 中找到了答案，但没有一个对我有用。 这是我所有的文件：

应用：

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 29
    buildToolsVersion '29.0.2'

    defaultConfig {
        applicationId "com.example.android.miwok"
        minSdkVersion 15
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}
dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'

}

ma​​in\AndroidManifest.xml：

Answer 1

您可能从 git 存储库“https://github.com/udacity/ud839_Miwok/tree/Starter-code”复制并粘贴了所有代码。而不是复制和粘贴，写入字符串值（例如，“ @string/category numbers") 在 AndroidManifest.xml 文件中。您看到此错误是因为 Android Studio 无法识别它。 确保res文件夹中的strings.xml文件完整。
