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。

# built application files
*.apk
*.ap_

# files for the dex VM
*.dex

# Java class files
*.class

# generated files
bin/
gen/

# Local configuration file (sdk path, etc)
local.properties

# Eclipse project files
.classpath
.project

# Proguard folder generated by Eclipse
proguard/

# Intellij project files
*.iml
*.ipr
*.iws
.idea/

Github为各种项目维护有用的gitignore条目。 下面是android项目中有用的gitignore项列表。

# Built application files
*.apk
*.ap_

# Files for the ART/Dalvik VM
*.dex

# Java class files
*.class

# Generated files
bin/
gen/
out/

# Gradle files
.gradle/
build/

# Local configuration file (sdk path, etc)
local.properties

# Proguard folder generated by Eclipse
proguard/

# Log Files
*.log

# Android Studio Navigation editor temp files
.navigation/

# Android Studio captures folder
captures/

# Intellij
*.iml
.idea/workspace.xml
.idea/tasks.xml
.idea/gradle.xml
.idea/libraries

# Keystore files
*.jks

# External native build folder generated in Android Studio 2.2 and later
.externalNativeBuild

# Google Services (e.g. APIs or Firebase)
google-services.json

# Freeline
freeline.py
freeline/
freeline_project_description.json

更新到Android Studio 3.0 请在评论中分享遗漏的项目。

一个迟来的答案，但这个替代答案不适合我们……

这是我们的gitignore文件:

#built application files
*.apk
*.ap_
*.aab
                           
# files for the dex VM
*.dex
                            
# Java class files
*.class
                            
# generated files
bin/
gen/
                            
# Local configuration file (sdk path, etc)
local.properties
                        
# Windows thumbnail db
Thumbs.db
                
# OSX files
.DS_Store
                            
# Android Studio
*.iml
.idea
#.idea/workspace.xml - remove # and delete .idea if it better suit your needs.
.gradle
build/
.navigation
captures/
output.json 
    
#NDK
obj/
.externalNativeBuild

从Android Studio 2.2到3.0，新项目都是用这个gitignore文件创建的:

*.iml
.gradle
/local.properties
/.idea/workspace.xml
/.idea/libraries
.DS_Store
/build
/captures
.externalNativeBuild

已弃用-对于旧的项目格式，将此部分添加到您的gitignore文件:

/*/out
/*/*/build
/*/*/production
*.iws
*.ipr
*~
*.swp

该文件应该位于项目的根文件夹中，而不是在项目的模块文件夹中。

编辑笔记:

从0.3+版本开始，似乎你可以提交和推送*。我和建造。gradle文件。如果你的项目基于Gradle:在新的打开/导入对话框中，你应该选中“使用自动导入”复选框，并标记“使用默认Gradle包装器(推荐)”单选按钮。所有路径现在都是相对的@George建议。 根据@128KB附件来源和@Skela建议更新了答案

这是使用http://gitignore.io/的引用创建的，在这里您可以为任何项目创建最新更新的gitignore文件。Android http://gitignore.io/api/androidstudio。希望这能有所帮助。目前我使用的是Android Studio 3.6.3

### AndroidStudio Patch ###

!/gradle/wrapper/gradle-wrapper.jar

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

从Android Studio 0.8.4开始，启动新项目时自动生成gitignore文件。默认情况下，它包含:

.gradle
/local.properties
/.idea/workspace.xml
/.idea/libraries
.DS_Store
build/
/captures

我同意这个说法，但是我修改了这个文件来改变 /建造到建造/ (包括/build和/app/build) 这样我就不会把所有的文件都放在app/build中。

还要注意，如果从Eclipse导入项目，.gitignore不会被复制，也不会“自动地”为您创建。
