Question

我一直在开发一款Linphone应用程序，但却陷入了困境。我已经更改了应用名称并重构了所有相关包。应用程序没问题，直到我将gradle升级到3.0.0。

AGPBI: {"kind":"error","text":"error: resource android:attr/fontStyle not found.","sources":[{"file":"~/.gradle/caches/transforms-1/files-1.1/support-compat-27.0.0.aar/61646c6d4479aff22f7047873e2edd7d/res/values/values.xml","position":{"startLine":20,"startColumn":4,"startOffset":1254,"endColumn":69,"endOffset":1319}}],"original":"","tool":"AAPT"}

我已经阅读了有关无法找到属性错误但无法找到答案的其他问题。我尝试了下面的方法，但没有一个工作：

删除应用程序的bin /目录
清理缓存并重新构建应用
使缓存无效并重新启动（其中的每个选项）
更改sdk版本（api）
multiDexEnabled true / false

以下是日志的详细信息：

Answer 1

要解决此问题，您应该：

安装mathching SDK版本（27）
在模块build.gradle中，您应将compileSdkVersion设置为27并更改com.android.support:appcompat-v7版本以匹配com.android.support:recyclerview-v7:（或您的其他支持库组件）使用）版本（27.0.0）

<强> UPD：

如果由于某种原因它对您没有帮助，请参阅@madu下面的评论

Answer 2

我能够通过将以下值更新为＆＃39; 27＆＃39;来解决此问题：

android {
    compiledSdkVersion 27

    defaultConfig {
        targetSdkVersion 27
    }
}

Answer 3

我遇到了同样的问题。只需调整compileSdkVersion和buildToolsVersion。

这是以前的版本：

这是没有问题的版本：

Answer 4

从v4：27.0.1降级到25.3.1后，好吧。之前res文件中有11个错误。

Answer 5

我曾尝试将targetSdkVersion降级，并将compileSdkVersion 27降级到25，但是当我发现有某种松散性时，就会出现此错误，并且效果很好

我只是在gradle文件的代码行下面添加了

configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == 'com.android.support') {

                details.useVersion '25.2.0'

        }
    }
}

如果您想将27降级到23、24、25等而不是更改详细信息。useVersion'_._._'<-放在此处yorr版本

Answer 6

我通过更新targetSdkVersion和compileSdkVersion解决了这个问题。

targetSdkVersion 28
compileSdkVersion 28

Answer 7

我遇到过同样的问题而且尚未解决问题。问题是com.android.support:support-v13或v7（可能是support-combat）依赖版本。如果是23.0.0或24.0.0则没有问题，但如果设置为27.0.0就会出现此错误。

Answer 8

我能够通过将以下值从“25”更新为“27”来解决此问题：

buildscript {
    repositories {
        jcenter()
        google()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
    }
}

apply plugin: 'com.android.application'

repositories {
    jcenter()
    google()
}

dependencies {
    implementation "com.android.support:support-v4:27.0.2"
    implementation "com.android.support:support-v13:27.0.2"
    implementation "com.android.support:cardview-v7:27.0.2"
    implementation "com.android.support:appcompat-v7:27.0.2"
    implementation 'com.android.support:recyclerview-v7:25.0.1'
    implementation 'com.android.support:design:25.0.1'
}

// The sample build uses multiple directories to
// keep boilerplate and common code separate from
// the main sample code.
List<String> dirs = [
    'main',     // main sample code; look here for the interesting stuff.
    'common',   // components that are reused by multiple samples
    'template'] // boilerplate code that is generated by the sample template process

android {
    compileSdkVersion 27

    buildToolsVersion '27.0.3'

    defaultConfig {
        minSdkVersion 24
        targetSdkVersion 27
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }

    sourceSets {
        main {
            dirs.each { dir ->
                java.srcDirs "src/${dir}/java"
                res.srcDirs "src/${dir}/res"
            }
        }
        androidTest.setRoot('tests')
        androidTest.java.srcDirs = ['tests/src']

    }

}

Answer 9

这只是一个缓存问题。内容在缓存文件中更新。

从中删除“ support-compat-27.0.0.aar”文件夹 C：/ USER /用户名/.gradle/caches/transforms-1/files-1.1/support-compat-27.0.0.aar / ...
注意：转到错误显示的路径。
构建项目。
运行您的应用。

它将解决您的问题。

Answer 10

我只是通过使用CTRL + SHIFT + F并在代码（整个作用域）中查找有问题的属性来找到问题的根源。在我看来，罪魁祸首是第三方的依赖。一旦我卸载它是固定的。我猜问题出在更新gradle以及这些过时的库以某种方式干扰了它。我仍然不完全了解问题的性质，但我希望这可以帮助其他人处理同一问题。我只是花了很长时间才看这个。在您的情况下，我想可能是v4和v7库的混合

Answer 11

也许卸载并重新安装整个android studio会有所帮助......记得备份你的项目。
