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

我支持提交。idea文件夹(不包括workspace.xml和tasks.xml)。但我开始得出结论，.iml文件应该被忽略。

问题在于:

例如，在名为“foo”的目录下打开一个项目，你将得到foo。我和那一切看起来都很好。问题是，如果我只是将目录重命名为foo2(或克隆为另一个目录名)，当你尝试在Android Studio中打开项目时，你会得到三件事:

一个名为foo2.iml的新iml文件 你的Android项目的iml文件将被更改为指向foo2作为它的父文件 .idea/modules.xml将为foo2添加一行。它既有旧的Iml文件，也有新目录的Iml文件

我找不到方法来阻止Android工作室做这个iml文件生成时，项目存储在一个不同的目录。将它们添加到源代码控制中会导致问题。因此，我认为也许我们应该忽略*。Iml文件和。idea/modules.xml

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

Android Studio 3.5.3

我在我的库和项目中使用这个，它涵盖了大多数由android studio和其他著名工具生成的文件:

# Built application files
*.apk
*.ap_
*.aab

# Files for the ART/Dalvik VM
*.dex

# Generated files
bin/
gen/
out/
app/release/

# Gradle files
.gradle/
build/

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

# 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/assetWizardSettings.xml
.idea/dictionaries
.idea/libraries
.idea/caches

# Keystore files
# Uncomment the following lines if you do not want to check your keystore files in.
#*.jks
#*.keystore

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

# Freeline
