未找到Android Studio 3 appcompat资源

嗨,我有一个Android Studio 3(Beta-2)的问题

每当我创建新的/打开现有的项目,它显示我以下错误:

错误

清理,重建,重新启动Studio,删除gradle文件不起作用。

在工作室2.3,一切都很好。

我的build.gradle文件:

 apply plugin: 'com.android.application' android { compileSdkVersion 25 buildToolsVersion "25.0.2" dataBinding.enabled = true defaultConfig { applicationId "com.valentun.findgift" minSdkVersion 16 targetSdkVersion 25 versionCode 1 versionName "1.0" testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" vectorDrawables.useSupportLibrary = true buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { exclude group: 'com.android.support', module: 'support-annotations' }) annotationProcessor 'com.jakewharton:butterknife-compiler:8.7.0' compile 'com.jakewharton:butterknife:8.7.0' compile 'com.google.dagger:dagger:2.11' annotationProcessor 'com.google.dagger:dagger-compiler:2.11' compile 'com.android.support:appcompat-v7:25.4.0' compile 'com.android.support:cardview-v7:25.4.0' compile 'com.android.support:design:25.4.0' compile 'com.google.firebase:firebase-storage:11.0.2' compile 'com.android.support.constraint:constraint-layout:1.0.2' compile 'com.squareup.picasso:picasso:2.5.2' compile 'com.squareup.retrofit2:converter-jackson:2.3.0' compile 'com.github.aakira:expandable-layout:1.6.0@aar' testCompile 'junit:junit:4.12' } apply plugin: 'com.google.gms.google-services' 

项目的渐进式文件:

 // Top-level build file where you can add configuration options common to all sub-projects/modules. buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:3.0.0-beta2' classpath 'com.google.gms:google-services:3.1.0' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } } allprojects { repositories { jcenter() maven { url 'https://jitpack.io' } maven { url "https://maven.google.com" } } } task clean(type: Delete) { delete rootProject.buildDir } 

从项目文件夹(C:\ Users ….. gradle)中删除Gradle文件(.gradle文件夹),然后尝试重新打开Android Studio。

希望这会有所帮助。

将版本25更改为26

 apply plugin: 'com.android.application' apply plugin: 'kotlin-android' apply plugin: 'kotlin-android-extensions' android { compileSdkVersion 26 buildToolsVersion "26.0.1" defaultConfig { applicationId "seesaa.vn.testandroidstudio" minSdkVersion 17 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' } } } dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) implementation"org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version" implementation 'com.android.support:appcompat-v7:26.0.1' implementation 'com.android.support.constraint:constraint-layout:1.0.2' testImplementation 'junit:junit:4.12' androidTestImplementation 'com.android.support.test:runner:1.0.0' androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.0' } 

您的编译SDK版本必须与支持库的主要版本相匹配。

由于您使用的是支持库的版本25,因此需要针对Android SDK的版本25进行编译。

尝试文件 – >无效缓存/重新启动 。 希望这会有所帮助。
