Android Studio の次期バージョンをいち早く入手したい場合は、既存の安定バージョンを置き換えなくても利用できます。Android Studio のプレビュー バージョンは、安定バージョンと同時にインストールできますので、同じアプリ プロジェクトを両方のバージョンで処理できます。
この処理ができるのは、Android Studio が、バージョン固有のフォルダに各インストールの設定を保管できるためです。たとえば、Android Studio 2.3 の安定版と Android Studio 3.0 のプレビュー版が Windows にインストールされている場合、各設定の保存先ディレクトリは次のようになります。

You can install the Android Studio preview side by side with the stable\nversion and work on the same app projects in both.\n\nThis is possible because Android Studio stores its settings for each install in version-specific\nfolders. For example, if you have the stable version of Android Studio 2.3\nand a preview version of Android Studio 3.0 installed on Windows, the settings for each\nare saved in directories such as the following: \n\n```\nC:\\Users\\Jamie\\.AndroidStudio2.3\\\nC:\\Users\\Jamie\\.AndroidStudioPreview3.0\\\n```\n\nOn Mac, these directories are in `~/Library/Preferences/` and\n`~/Library/Application Support/`. On Linux, they're in your home directory.\n\nBy default, all Android Studio installations share the same Android SDK tools location as\nspecified in the [SDK Manager](/studio/intro/update#sdk-manager), so updates to your other\nSDK tools are available in all versions of Android Studio.\n| **Note:** Newer versions of Android Studio might change some configuration data in your projects (such as code style settings in the `.idea` file), which might not be compatible with the older version of Android Studio.\n\nIf you don't already have it, [download Android Studio stable here](/studio). It's good to have\njust in case you encounter a new bug in the preview version.\n\nInstall alongside your stable version\n-------------------------------------\n\nAfter you [download an Android Studio preview](/studio/preview), simply save the application\nalongside any other version of Android Studio as described below.\n\n**Windows:**\n\n1. Unpack the ZIP file.\n2. Rename the resulting folder to something unique like \"Android Studio Preview.\"\n3. Move it to a permanent location, such as next to your existing Android Studio install in `C:\\Program Files\\Android\\`.\n4. Inside `C:\\Program Files\\Android\\Android Studio Preview\\bin\\`, launch `studio64.exe` (or if you're on a 32-bit machine, launch `studio.exe`).\n5. To make the preview version available in your Start menu, right-click `studio64.exe` and click **Pin to Start Menu**.\n\n**Mac:**\n\n1. Unpack the ZIP file. **Note:**\n If you download version 2.3 or lower, the application name does not\n include the version number, so you must first rename it before moving\n the new version into your apps directory. Otherwise, you might override your\n existing version of Android Studio.\n\n2. Drag the app file into your **Applications** folder.\n3. Now launch it.\n\n**Linux:**\n\n1. Unpack the ZIP file.\n2. Rename the resulting folder to something unique like \"android-studio-preview.\"\n3. Move it to wherever you have your stable version, such as within `/usr/local/` for your user profile, or `/opt/` for shared users.\n4. Open a terminal, navigate into `android-studio-preview/bin/` and execute `studio.sh`."]]
