最好在整个开发过程中添加.gitignore列表，以防止版本控制由于某处预定义的(复制/粘贴)列表而无法工作时产生未知的副作用。对于我的一个项目，忽略列表只有:

.gradle
.idea
libs
obj
build
*.log

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!；）

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

为了更好地理解，您只需要以下文件

应用程序 build.gradle settings.gradle

您可以将其他所有内容放在.gitignore文件中。你所有的应用变化都在这些文件和文件夹中。你在基本项目中看到的其他文件是gradle构建文件或Android Studio配置文件。

如果你正在使用Android Studio，你可以使用“Import project”来成功构建项目。或者你也可以使用命令行构建，使用Gradle构建Android项目。

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:
