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/

我有忽略构建文件的问题，但这似乎是有效的:-)

# 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

# Android Studio
.idea/
.gradle
/*/local.properties
/*/out
/*/*/build
/*/*/production
*.iml
*.iws
*.ipr
*~
*.swp

*/build
*/production
*/local.properties
*/out

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

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。

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

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
