我已经对这个问题进行了很多搜索，但对我没有任何帮助。我刚刚将 Android Studio 更新到 2.2 Preview 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（模块应用程序）：

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：我已经能够构建和安装 APK 一次，但大多数时候我收到此错误或“未知错误”。

EDIT2：在 Gradle Build 上我得到：

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

在 Gradle 控制台上，我得到：

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

去File - Invalidate Cache and Restart。除非您build.gradle在更新后更改了某些内容，否则您应该会很好。如果你这样做了，请恢复并检查这是否是导致问题的原因。
