使用gitignore提供的api。Io，你可以得到的是自动生成的。这里是gitignore.io/api/androidstudio的直接链接

### AndroidStudio Patch ###

!/gradle/wrapper/gradle-wrapper.jar

# End of https://www.gitignore.io/api/androidstudio

这份来自JetBrains Support的官方文档认为应该包含以下内容:

All files under .idea directory except workspace.xml and tasks.xml because
    they store specific user settings
All the *.iml files that can be located in different module directories

它还给出了其他需要注意的事项的建议。

不需要在源代码控件中添加以下任何内容:

.idea/
.gradle/
*.iml
build/
local.properties

所以你可以相应地配置hgignore或gitignore。

开发人员第一次克隆源代码控件时可以这样做:

Open Android Studio 导入项目 浏览构建。Gradle在克隆的存储库中并打开它

这是所有

PS: Android Studio将通过maven获得gradle插件，假设您的构建。Gradle看起来像这样:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.12.2'
    }
}

allprojects {
    repositories {
        mavenCentral()
    }
}

Android studio将生成.idea文件夹(包括workspace.xml，它不应该在源代码控制中，因为它是生成的)和.gradle文件夹的内容。

这种方法是eclipse友好的，因为源代码控制并不真正了解Android Studio。Android Studio只需要构建。Gradle导入项目并生成其余部分。

Android Studio Chipmunk 2021.2.1

如果你使用Android Studio创建Gradle项目，.gitignore文件将包含以下内容:

. gitignore

*.iml
.gradle
/local.properties
/.idea/caches
/.idea/libraries
/.idea/modules.xml
/.idea/workspace.xml
/.idea/navEditor.xml
/.idea/assetWizardSettings.xml
.DS_Store
/build
/captures
.externalNativeBuild
.cxx
local.properties

我建议忽略完整的”。目录，因为它包含特定于用户的配置，对于构建过程没有什么重要的。

Gradle项目文件夹

在存储库克隆之后，你的(Gradle)项目文件夹中唯一应该存在的东西是这样的结构(至少对于我目前遇到的用例来说是这样的):

app/
.git/
gradle/
build.gradle
.gitignore
gradle.properties
gradlew
gradlew.bat
settings.gradle

注意:建议像这里描述的那样签入gradle包装器脚本(gradlew, gradlew.bat)。

要使Wrapper文件对其他开发人员和执行环境可用，您需要将它们检入版本控制。

基本上是自动重新生成的任何文件。

一个很好的测试是克隆你的repo，看看Android Studio是否能够立即解释和运行你的项目(生成缺少的东西)。 如果没有，找到丢失的内容，并确保它没有被忽略，而是添加到回购中。

也就是说，你可以在现有的.gitignore文件上举例，比如Android文件。
