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

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

我的建议是不要忽略。idea文件夹。

我已经将一个基于git的Eclipse项目导入到Android Studio，效果很好。后来，我想用Git导入这个项目(就像第一次一样)到另一台带有Android Studio的机器上，但没有成功。Android Studio确实加载了所有文件，但无法将项目“视为”项目。我只能打开Git-files。

当第一次导入项目(从Eclipse到Android Studio)时，我的旧的.gitignore被覆盖了，新的看起来像这样:

.idea / . name .idea / compiler.xml .idea /版权/ profiles_settings.xml .idea / encodings.xml .idea /图书馆/ libs.xml .idea / misc.xml .idea / modules.xml .idea /范围/ scope_settings.xml .idea / vcs.xml .idea / workspace.xml

所以，我试着用一个空的gitignore，现在它工作了。另一个Android Studio可以加载文件和项目。我猜有些文件对于Git和导入来说并不重要(profiles_settings.xml)，但我很高兴它起作用了。

我知道这是一个老话题，当然有很多选择，但我真的更喜欢西蒙惠特克的gibo。它使用起来超级简单，跨平台(mac， *nix和windows)，并使用github gitignore repo，所以它(基本上)总是最新的。

确保你的本地缓存是最新的:

    $ gibo --upgrade
    From https://github.com/github/gitignore
     * branch            master     -> FETCH_HEAD
    Current branch master is up to date.

搜索你需要的语言/技术:

    $ gibo --search android
    Android

显示.gitignore文件:

    $ gibo Android
    ### Android

    # Built application files
    *.apk
    *.ap_

    # Files for the Dalvik VM
    *.dex

    # Java class files
    *.class

    # Generated files
    bin/
    gen/

    # Gradle files
    .gradle/
    build/

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

    # Proguard folder generated by Eclipse
    proguard/

    # Log Files
    *.log

现在，将它附加到项目的.gitignore文件中:

    $ gibo Android >> .gitignore

(确保你使用>>附加到你的项目的。gitignore文件;一个>将覆盖它-因为我已经做了很多次意外!)

我知道这不是回答OP的确切问题，但使用gibo使它使你几乎不必再考虑“问题”!. .很高兴!；）
