Question

我已经搜索了很多关于这个问题的内容，但没有任何对我有用。我刚刚将Android Studio更新为2.2预览版3，我收到以下错误：

Gradle'myApp' project refresh failed

我检查了我的gradle设置，清理并重建了我的项目甚至删除了.gradle文件。

这是我的build.gradle（模块应用）：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion '24.0.0'

    defaultConfig {
        applicationId "fogames.thecolourapp"
        minSdkVersion 12
        targetSdkVersion 24
        versionCode 4
        versionName "1.0.3"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:24.0.0'
    compile 'com.android.support:design:24.0.0'
    compile 'com.google.android.gms:play-services-appindexing:9.2.1'
    compile 'com.android.support:support-v4:24.0.0'
}

编辑：我已经能够构建并安装一次APK，但大部分时间我都会收到此错误或“未知错误”。

EDIT2：关于Gradle Build我得到：

Error:Failed to complete Gradle execution. Cause: unknown.

在Gradle控制台上，我得到：

Executing tasks: [:app:generateDebugSources, :app:compileDebugSources]

转到File - Invalidate Cache and Restart。除非您在更新后更改了build.gradle中的内容，否则您应该做得很好。如果您这样做，请还原并检查是否是导致问题的原因。
