you've given us any critical feedback before non-beta users start getting Android 15.</p> <h1 style="text-align: left;"><span style="font-size: x-large;">What's in Beta 4?</span></h1> <p>This is our second <a href="https://developer.android.com/about/versions/15/overview#platform_stability" target="_blank">Platform Stability</a> release; the developer APIs and all app-facing behaviors are final for you to review and integrate into your apps, and apps targeting Android 15 can be made available in Google Play. Beta 4 includes our latest fixes and optimizations, giving you everything you need to complete your testing. Head over to our <a href="https://developer.android.com/about/versions/15/summary" target="_blank">Android 15 summary page</a> for a list of the features and behavior changes we've been covering in this <a href="https://android-developers.googleblog.com/search?q=Android+15" target="_blank">series of blog posts</a>, or read on for some of the top changes to be aware of.</p> <image><div style="text-align: center;"><img alt="Timeline of Android 15 release schedule" border="0" id="imgCaption" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi4SpnV5kD_e-FuS3p-PaveD2DEEP014RYaj30Ck_hH0AeHQulsCiLc9cWeP478OaawXrpuojFnJd5V8ogRXXde-NrXz0IMT8mf1XRzQNU9caNioZdymZJWGVPx8gbY_RSC06Pnd_DY1jBiEk3Z8VvwfUv0HhdhQW6HJP-ZPgBAQaKhdv95E5O9i_zkBxM/s1600/image1.png" width="100%" /></div></image> <h3 style="text-align: left;"><span style="font-size: large;">Removed PNG-based emoji font</span></h3> <p>Android 15 removes the legacy PNG-based emoji font file (NotoColorEmojiLegacy.ttf) meaning that some Android 15 devices such as Pixel will only have the vector-based file. Beginning with Android 13, the emoji font file used by the system emoji renderer changed from a PNG-based file to a vector based file. We kept the old font file around in Android 13 and 14 for compatibility reasons, so that applications with their own font renderers could continue to use the old font until they were able to upgrade.</p> <p>You can choose to adapt your app in a number of ways:</p> <ul><ul> <li>Use platform text rendering. You can render text to a bitmap-backed <span style="font-family:Courier;"><a href="https://developer.android.com/reference/android/graphics/Canvas" target="_blank">Canvas</a></span> and use that to get a raw image if necessary.</li></ul></ul><ul><ul> <li>Make sure your text library <a href="https://developer.chrome.com/blog/colrv1-fonts" target="_blank">supports COLRv1 fonts</a>. The <a href="https://freetype.org/" target="_blank">FreeType</a> open source library version <a href="https://sourceforge.net/projects/freetype/files/freetype2/2.13.0/" target="_blank">2.13.0</a> or later supports it.</li></ul></ul><ul><ul> <li>As a last resort, you can <a href="https://github.com/googlefonts/noto-emoji/blob/main/fonts/NotoColorEmoji.ttf" target="_blank">bundle the legacy emoji font</a> (currently 10.1MB) into your APK.</li> </ul></ul> <h2 style="text-align: left;"><span style="font-size: x-large;">Get your apps, libraries, tools, and game engines ready!</span></h2> <p>If you develop an SDK, library, tool, or game engine, it's important to prepare any necessary updates now to prevent your downstream app and game developers from being blocked by compatibility issues and allow them to target the latest SDK features. Please let your developers know if updates are needed to fully support Android 15.</p> <p>Testing your app involves installing your production app using Google Play or other means onto a device or emulator running Android 15 Beta 4. Work through all your app's flows and look for functional or UI issues. Review the <a href="https://developer.android.com/about/versions/15/behavior-changes-all" target="_blank">behavior changes</a> to focus your testing. Each release of Android contains platform changes that improve privacy, security, and overall user experience, and these changes can affect your apps. Here are several changes to focus on that apply even if you don't yet target Android 15:</p> <ul><ul> <li><a href="https://developer.android.com/about/versions/15/behavior-changes-all#enhanced-stop-states" target="_blank">Package stopped state changes</a> - Android 15 updates the behavior of the package <span style="font-family:Courier;"><a href="https://developer.android.com/reference/android/content/pm/ApplicationInfo#FLAG_STOPPED" target="_blank">FLAG_STOPPED</a></span> state to keep apps stopped until the user launches or indirectly interacts with the app.</li></ul></ul><ul><ul> <li><a href="https://developer.android.com/about/versions/15/behavior-changes-all#16-kb" target="_blank">Support for 16KB page sizes</a> - Beginning with Android 15, Android supports devices that are configured to use a page size of 16 KB. If your app or library uses the NDK, either directly or indirectly through an SDK, then you will likely need to rebuild your app for it to work on these devices.</li></ul></ul><ul><ul> <li><a href="https://developer.android.com/about/versions/15/behavior-changes-all#private-space-changes" target="_blank">Private space support</a> - <a href="https://developer.android.com/about/versions/15/features#private-space" target="_blank">Private space</a> is a new feature in Android 15 that lets users create a separate space on their device where they can keep sensitive apps away from prying eyes, under an additional layer of authentication.</li> </ul></ul> <p>Remember to thoroughly exercise libraries and SDKs that your app is using during your compatibility testing. You may need to update to current SDK versions or reach out to the developer for help if you encounter any issues.</p> <p>Once you’ve published the Android 15-compatible version of your app, you can start the <a href="https://developer.android.com/preview/migration#setup_sdk" target="_blank">process</a> to <a href="https://developer.android.com/distribute/best-practices/develop/target-sdk" target="_blank">update your app's <span style="font-family:Courier;">targetSdkVersion</span></a>.
