||
| Privacy | Private space Private space 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. Apps in the private space show up in a separate container in the launcher, and are hidden from the recents view, notifications, settings, and from other apps when the private space is locked. |

This update adds support for data types across fitness, nutrition, skin temperature, training plans, and more. |
||
| Privacy | Partial screen sharing Android 15 supports partial screen sharing so users can share or record just an app window rather than the entire device screen. This feature, first enabled in Android 14 QPR2, includes MediaProjection callbacks that allow your app to customize the partial screen sharing experience. |
||
| Security | Integrate Credential Manager with autofill Starting with Android 15, developers can link specific views like username or password fields with Credential Manager requests, making it easier to provide a tailored user experience during the sign-in process. |

Also, in-progress media projection is automatically stopped when the device screen is locked. |
Change (all apps)
| Qt | Qt Detail | Domain | Detail |
|
AudioTrack directly used in qtmultimedia in QtAudioDeviceManager.java and qopenslesengine.cpp QTBUG-137397 |
Camera and media | Direct and offload audio playback invalidates previously open direct or offload audio tracks when resource limits are reached Beginning with Android 15, when an app requests direct playback, the system invalidates any currently open direct AudioTrack objects which prevent fulfilling the new track request. |
|
FLAG_STOPPED not directly used | Core functionality | Changes to package stopped state In Android 15, apps are only be removed from the FLAG_STOPPED state through direct or indirect user action. In addition to the existing restrictions, the system also cancels all pending intents when the app enters the stopped state on Android 15. |
|
C++ impacted. Qt 6.5 & 6.8 LTS (NDK27). NDK29 & AGP 8.5.1 <= should support it. QTBUG-131514 |
Core functionality | Support for 16 KB page sizes Beginning with Android 15, the Android system supports development devices that are configured to use a page size of 16 KB. If you use native code in your app, you should rebuild your app with support for 16 KB devices, and all developers should test their apps using a 16 KB environment to verify that there are no unexpected regressions in app behavior. |
|
If Qt (Quick) for Android (Automotive) app is medical or launcher app read this. QtAA QAA-2975 | Core functionality | Required changes for some apps to support private space Private space is a 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. Because apps in the private space have restricted visibility, some types of apps need to take additional steps to be able to see and interact with apps in a user's private space. |
|
Not used | Core functionality | PNG-based emoji font removed The legacy, PNG-based emoji font file (NotoColorEmojiLegacy.ttf) has been removed, leaving just the vector-based file. |
|
Qt 6.5 LTS forward minimum supported SDK 26 Qt 5.15 LTS does not support Android 15 |
Core functionality | Minimum installable target API level Apps with a targetSdkVersion lower than 24 can't be installed. |
|
No Qt implementation QTBUG-103569 | User experience and system UI | Predictive back animations enabled for apps that opted in The developer option for predictive back animations has been removed. Instead, system animations such as back-to-home, cross-task, and cross-activity appear for apps that have opted in to the predictive back gesture either entirely or at an activity level. |
Change (app targeting Android 15 <=)
| Qt | Qt Detail | Domain | Detail |
|
Not used; requestAudioFocus, focusRequest nor AudioFocus | Camera and media | Restrictions on requesting audio focus Apps that target Android 15 must be the top app or running an audio-related foreground service in order to request audio focus. |
| Core functionality | Media processing foreground service type Android 15 introduces a new foreground service type, mediaProcessing. This service type is appropriate for operations like transcoding media files. |
||
| Core functionality | Restrictions on BOOT_COMPLETED broadcast receivers launching foreground services For apps targeting Android 15, BOOT_COMPLETED receivers are not allowed to launch some types of foreground services. |
||
| Core functionality | Changes to when apps can modify the global state of Do Not Disturb mode Apps that target Android 15 can no longer change the global state or policy of Do Not Disturb (DND) on a device (either by modifying user settings, or turning off DND mode). |
||
| Core functionality | OpenJDK API changes As part of the OpenJDK API updates, there are some changes that can affect app compatibility, such as changes to some string formatting APIs, language code handling, and random int sequences. |
||
| Non-SDK interface restrictions | Updates to non-SDK interface restrictions Android 15 includes updated lists of restricted non-SDK interfaces based on collaboration with Android developers and the latest internal testing. |
||
| Security | Restricted TLS versions Android 15 restricts the usage of TLS versions 1.0 and 1.1. These versions had previously been deprecated in Android, but are now disallowed for apps targeting Android 15. |
||
| Security | Secured background activity launches For apps targeting Android 15, we've included further changes to prevent malicious background apps from bringing other apps to the foreground, elevating their privileges, and abusing user interaction. |
||
| Security | Safer intents For apps targeting Android 15, intents that target specific components must accurately match the target's intent-filter specifications, and intents without an action no longer match any intent filters. |
||
|
SafeArea margins covers this Qt 6.9 <= Qt 6.5 & 6.8 LTS's does not support it, but Android 15 has a flag\ to disable the feature. |
User experience and system UI | Edge-to-edge enforcement For apps that target Android 15, we're including several changes related to edge-to-edge. Your app's user experience might be negatively impacted by these changes if your app has UI elements near the top or bottom of the screen and your app doesn't handle insets. |
| User experience and system UI | Stable configuration If your app targets Android 15 or higher, Configuration no longer excludes the system bars. |
||
| User experience and system UI | elegantTextHeight attribute defaults to true For apps targeting Android 15, the elegantTextHeight TextView attribute becomes true by default, replacing the compact font used by default with some scripts that have large vertical metrics with one that is much more readable. |
||
| User experience and system UI | TextView width changes for complex letter shapes In previous versions of Android, some cursive fonts or languages that have complex shaping might draw the letters in the previous or next character's area. In some cases, such letters were clipped at the beginning or ending position. Starting in Android 15, a TextView allocates width for drawing enough space for such letters and allows apps to request extra paddings to the left to prevent clipping. |
||
| User experience and system UI | Locale-aware default line height for EditText For apps targeting Android 15, a minimum line height is reserved for EditText to match the reference font for the specified Locale. |
Deprecation (from Android 15 <=)
| Qt | Qt Detail | Domain | Detail |
|
Not used | Camera and media | Use Spatializer instead of Virtualizer In Android 15, we're deprecating the Virtualizer class. |
