Android Studio 2.3：无法在android中使用字符串资源：versionName

Question

我今天升级了Android Studio 2.2 - > 2.3，并且在Android Studio中构建我的应用程序时，现在有一个编译器错误，我之前没有。

Error:No resource found that matches the given name (at 'versionName' with value '@string/BRAND_VERSION'). 

这是字符串资源。

<string name="BRAND_VERSION">2.0</string> 

这是清单中的相关部分。

<manifest package="com.metaswitch.cp.unbrandedpackage" 
     xmlns:android="http://schemas.android.com/apk/res/android" 
     xmlns:tools="http://schemas.android.com/tools" 
     android:versionCode="5" 
     android:versionName="@string/BRAND_VERSION"> 

据Android documentation，字符串资源被允许在中的versionName清单或的build.gradle。

这不是特定于我的应用程序。我可以用此代替Android sample

它构建和安装对我来说很好。当我将这一行更改为build.gradle中的versionName（从strings.xml中选取一个随机字符串资源）时，它会失败并显示相同的错误。

// versionName "1.0" 
versionName "@string/add_task" 

这是Android示例中的build.gradle（注意我的编辑为versionName）。

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion rootProject.ext.compileSdkVersion 
    buildToolsVersion rootProject.ext.buildToolsVersion 

    defaultConfig { 
     applicationId "com.example.android.architecture.blueprints.todomvploaders" 
    minSdkVersion rootProject.ext.minSdkVersion 
    targetSdkVersion rootProject.ext.targetSdkVersion 
    versionCode 1 
    // I really want to use a string resource here! 
    // versionName "1.0" 
    versionName "@string/add_task" 

    testInstrumentationRunner 'android.support.test.runner.AndroidJUnitRunner' 
} 

buildTypes { 
    debug { 
     minifyEnabled true 
     // Uses new built-in shrinker http://tools.android.com/tech-docs/new-build-system/built-in-shrinker 
     useProguard false 
     proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     testProguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguardTest-rules.pro' 
    } 

    release { 
     minifyEnabled true 
     useProguard true 
     proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     testProguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguardTest-rules.pro' 
    } 
} 

// If you need to add more flavors, consider using flavor dimensions. 
productFlavors { 
    mock { 
     applicationIdSuffix = ".mock" 
    } 
    prod { 

    } 
} 

// Remove mockRelease as it's not needed. 
android.variantFilter { variant -> 
    if(variant.buildType.name.equals('release') 
      && variant.getFlavors().get(0).name.equals('mock')) { 
     variant.setIgnore(true); 
    } 
} 

// Always show the result of every unit test, even if it passes. 
testOptions.unitTests.all { 
    testLogging { 
     events 'passed', 'skipped', 'failed', 'standardOut', 'standardError' 
    } 
} 
buildToolsVersion '25.0.0' 

}

Answer 1

我升级过Android Studio后有同样的问题。关闭首选项的即时运行有助于应用程序再次运行。

Answer 2

参考Google issue tracker，这已经是固定。这可与Android studio 3.0.0-alpha6 build。

如果有任何问题仍然存在，请在Google issue tracker举报，他们将重新开放审查。
