我用这个。gitignore。我在http://th4t.net/android-studio-gitignore.html找到了它

*.iml
*.iws
*.ipr
.idea/
.gradle/
local.properties

*/build/

*~
*.swp

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/

编译:

#built application files
*.apk
*.ap_

# files for the dex VM
*.dex

# Java class files
*.class

# generated files
bin/
gen/

# Gradle files
.gradle/
build/
/*/build/

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

# Proguard folder generated by Eclipse
proguard/

# Log Files
*.log

# Windows thumbnail db
Thumbs.db

# OSX files
.DS_Store

# Eclipse project files
.classpath
.project

# Android Studio
*.iml
.idea
#.idea/workspace.xml - remove # and delete .idea if it better suit your needs.
.gradle
build/

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

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。

在我正常的Android .gitignore的基础上，在阅读Intellij IDEA网站上的文档和阅读StackOverflow上的帖子后，我构建了以下文件:

# built application files
*.apk
*.ap_

# files for the dex VM
*.dex

# Java class files
*.class

# built native files (uncomment if you build your own)
# *.o
# *.so

# generated files
bin/
gen/

# Ignore gradle files
.gradle/
build/

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

# Proguard folder generated by Eclipse
proguard/

# Eclipse Metadata
.metadata/

# Mac OS X clutter
*.DS_Store

# Windows clutter
Thumbs.db

# Intellij IDEA (see https://intellij-support.jetbrains.com/entries/23393067)
.idea/workspace.xml
.idea/tasks.xml
.idea/datasources.xml
.idea/dataSources.ids

还要注意，正如所指出的，当你用Android NDK构建自己的本机代码时，构建的本机文件部分主要是有用的。另一方面，如果您正在使用包含这些文件的第三方库，则可能希望删除这些行(*。O和*.so)来自你的。gitignore。
