Google Play 免安裝功能可讓搭載 Android 5.0 (API 級別 21) 以上版本的裝置啟動原生應用程式和遊戲，不必安裝。您可以使用 Android Studio 建構這類體驗，也就是免安裝應用程式和免安裝遊戲。讓使用者執行免安裝應用程式或遊戲 (即提供免安裝體驗)，有助於提升應用程式或遊戲的曝光度，吸引更多活躍使用者或使更多人安裝。
本指南將概略介紹 Google Play 免安裝體驗。
即時體驗的運作方式
有了 Google Play 免安裝技術，使用者只要輕觸 Play 商店、Google Play 遊戲應用程式或網站橫幅中的按鈕，即可使用應用程式或暢玩遊戲，不必先行安裝。圖 1 和圖 2 顯示這些探索介面的範例。
Google Play 收到即時應用程式或遊戲的這類要求後，會將必要檔案傳送至傳送要求的 Android 裝置。裝置隨即執行應用程式或遊戲。
免安裝體驗分為兩類：Google Play 商店中的「試用」體驗，以及 Google Play 遊戲應用程式中的「免安裝試玩」遊戲。

Starting December 2025,\nInstant Apps cannot be published through Google Play, and all\n[Google Play services Instant APIs](https://developers.google.com/android/reference/com/google/android/gms/instantapps/package-summary)\nwill no longer work. Users will no longer be served Instant Apps by Play using any\nmechanism.\n\nWe're making this change based on developer feedback and our continuous investments\nto improve the ecosystem since the introduction of Google Play Instant.\n\nTo continue optimizing for user growth, we encourage developers to refer users to\ntheir regular app or game, using [deeplinks](https://support.google.com/googleplay/android-developer/answer/12463044)\nto redirect them to specific journeys or features when relevant.\n\nGoogle Play Instant enables native apps and games to launch on devices\nrunning Android 5.0 (API level 21) or higher without being installed. You can build these\ntypes of experiences, called *instant apps* and *instant games* , using Android\nStudio. By allowing users to run an instant app or instant game, known as\nproviding an *instant experience*, you improve your app or game's discovery,\nwhich helps drive more active users or installations.\n| **Note:** Instant apps and games can use only a subset of APIs within the Android SDK and the Android NDK. When creating an instant experience, make sure you [request only supported permissions](/topic/google-play-instant/getting-started/instant-enabled-app-bundle#request-supported-permissions).\n\nThis guide presents an overview of the Google Play Instant experience.\n\nHow the instant experience works\n--------------------------------\n\nWith Google Play Instant, users can tap on\na button in the Play Store, Google Play Games app, or a website banner to use an app or game without\ninstalling it first. Figures 1 and 2 show examples of these discovery surfaces.\n\nWhen Google Play receives one of these requests for an instant app or game, it\nsends the necessary files to the Android device that sent the request. The\ndevice then runs the app or game.\n\nInstant experiences fall into two categories: \"Try\" experiences in the Play\nStore and \"Instant play\" games in the Google Play Games app. \n**Figure 1.** The **Try Now** button that appears on an instant-enabled app or game's page on Google Play \n**Figure 2.** The **Instant play** button appears on a full experience game in the [Google Play Games app](https://play.google.com/store/apps/details?id=com.google.android.play.games)\n\n### Instant \"Try\" experience in the Play Store\n\nInstant experiences are shown using a **Try now** button in the Play Store (as shown in Figure 1). This\ntype of experience is typically a smaller trial version of your app or game\ncreated with the goal of driving installs. For example, game developers may want\nto build the first level of their game as an instant experience and then prompt\nusers to install the full game.\n\nGoogle Play Instant also allows you to [display a\nprompt](/topic/google-play-instant/getting-started/instant-enabled-app-bundle#install-prompt)\nwithin your instant experience, inviting users to install the full experience on\ntheir device.\n\n### \"Instant play\" full game experience in the Play Games app\n\nFull games that are packaged using Google Play Instant are eligible to be\nfeatured prominently on the homepage of the\n[Google Play Games app](https://play.google.com/store/apps/details?id=com.google.android.play.games). These \"Instant play\" games are *full experience* games, not trial versions. Players tap\non the **Instant play** button (as shown in Figure 2) to play the full game\nwithout installing it first. To learn more, see\n[Instant play games](/topic/google-play-instant/instant-play-games).\n\nEnable instant experiences by reducing app or game size\n-------------------------------------------------------\n\nYour app or game must be under 15 MB to enable these instant experiences,\nbut the smaller you make it, the better it will be for users.\n\nReducing the size of your instant app or game has a number of benefits including:\n\n- Higher user engagement or installations and business success\n- Enabling all instant surfaces including the **Try now** button in the Play Store\n- \"Instant play\" homepage featuring in the Google Play Games app\n\nTo learn how you can reduce the size of your app or game, see [Reduce the size\nof your instant app or\ngame](/topic/google-play-instant/guides/reduce-module-size).\n\nConsiderations\n--------------\n\nSome apps contain more advanced architectural elements, which the following\nsections describe. If your app or game contains any of the following elements,\nread the section for that element.\n\n### Deep links\n\nIf your existing app already uses deep links or Android App Links, see the guide\non how to [create app links for your instant\nexperience](/training/app-links/instant-app-links).\n| **Note:** Users can opt out of opening links within apps. A menu in the device's system settings called **Instant apps** provides this option.\n\n### Multiple entry points\n\nIt's possible to provide different instant experiences from the same app or game\nby creating multiple entry points. For example, a puzzle game might have two\ndifferent modes: a single-player, timed challenge and a multi-player matchup.\nYou could deploy these modes as separate instant experiences, allowing players\nto try out different aspects of gameplay.\n\nTo create these different entry points, configure a different entry point\nfor each experience that you'd like to provide. To learn more, see [Provide\nmultiple entry points into an instant\nexperience](/topic/google-play-instant/guides/multiple-entry-points).\n| **Caution:** Don't use a central routing activity in your instant experience. Instead, provide multiple entry points so that the Android framework does the routing for you. This approach enables you to achieve more modularization in your app or game.\n\nLearn more\n----------\n\nTo learn more about Google Play Instant, see the following resources:\n\n- [List of known\n issues](https://issuetracker.google.com/issues?q=status%3Aopen+componentid%3A316045)\n- [StackOverflow component for instant apps](https://stackoverflow.com/questions/tagged/android-instant-apps)\n- [Developer stories](/stories/instant-apps)\n\nAdditional resources\n--------------------\n\nFor more information about Google Play Instant, consult the following\nresources.\n\n### Training\n\n- Google I/O 2018: [The future of apps on Android and Google Play: modular,\n instant, and dynamic](https://www.youtube.com/watch?v=0raqVydJmNE&t=1057s)\n- Google I/O 2018: [How game developers are providing\n success](https://youtu.be/LN1YQeo6yNk)"]]
