AndroidVersionAdapter
1.0.0
Project address: Github
It was very painful when I was doing Android version adaptation work. At that time, I was wondering if there was a document that could collect all the information about Android version adaptation, so that I wouldn’t need to look around online. can devote time and energy to adaptation work. Whenever a new Android version is released, this idea becomes stronger and stronger. Finally, we planned this matter when Android 11 was just released, and finally rushed to Android 12. It was completed when it was first released. The whole process took a long time because I was constantly collecting high-quality information. At the same time, I was also constantly thinking about what kind of adaptation documents everyone needed. I will simply divide the adaptation documents into Became the following parts:
Official documentation
new features
behavior change

Adaptation framework link
Why make this an open source project? Because I will continue to update, and if you have good articles, you can recommend them to me through issues. I will put them up after I review them. Making an open source project requires everyone's contribution. Open source is a process of mutual help. There is no It’s hard for me to do it well with everyone’s support.
Android 14 as an example. The first step is to modify the values of targetSdkVersion and compileSdkVersion in the build.gradle file in the main module. android {
compileSdkVersion 34
defaultConfig {
......
targetSdkVersion 34
}
} if ( Build . VERSION . SDK_INT >= Build . VERSION_CODES . UPSIDE_DOWN_CAKE ) {
......
} else {
......
} if ( context . getApplicationInfo (). targetSdkVersion >= Build . VERSION_CODES . UPSIDE_DOWN_CAKE ) {
......
} else {
......
}At this point, you may have a question, what is the difference between targetSdkVersion and compileSdkVersion?
targetSdkVersion: Target adaptation version, informs the system of App adaptation situation. If the application's targetSdkVersion is lower than the system version, then the new system will perform downward compatibility processing on some new features. If we want to adapt to an Android version, the targetSdkVersion must be adjusted to be above this version level, otherwise some adaptation abnormalities may occur on some models. If we simply increase the targetSdkVersion level without adapting to the features of the new version, the application may function abnormally on the new system. Generally, the application crashes or cannot obtain data.
compileSdkVersion: Compile source code version. We can change the version of the Android SDK source code we see in the code by modifying this version level. It also determines the version used by the compiler when performing code inspection.
Finally, a corresponding table of Android version information is attached.

Android API Levels
Distribution Information Center (Google Official)
Top Android OS versions (requires circumvention)
Mobile & Tablet Android Version Market Share Worldwide
Mobile Android operating system market share by version worldwide from January 2018 to January 2022
Requirements that Google Play applications need to meet in terms of target API levels (need to circumvent the firewall)
Each new Android version introduces changes to improve security and performance, and improve the overall Android user experience. Each application's manifest file has a targetSdkVersion parameter (also called the target API level), which tells the system how your application should run on different Android versions.
Configuring your app's target API level to a recent API level ensures that users enjoy security, privacy, and performance improvements while still allowing your app to run on older versions of Android (down to minSdkVersion ).
To provide Android and Google Play users with a safe and secure experience, Google Play requires all apps to meet the following requirements for target API levels.
| new application | Apps that are not yet published on the Play Store (for example, brand new apps) |
|---|---|
| Apply updates | New versions of apps published on the Play Store |
| Existing applications | Published apps not getting updates |
| Android OS version | new application | Apply updates | Existing applications |
|---|---|---|---|
| Android 13 (API level 33) | August 1, 2023 | November 1, 2023 | November 1, 2024 |
| Android 12 (API level 31) | August 1, 2022 | November 1, 2022 | November 1, 2023 |
| Android 11 (API level 30) | August 1, 2021 | November 1, 2021 | November 1, 2022 |
Tip : For technical guidance on changing your app's target API level to meet the above requirements, see the migration guide.
| Android OS version | new application | Apply updates | Existing applications |
|---|---|---|---|
| Android 11 (API level 30) | August 1, 2022 | November 1, 2022 | No requirement |
| Android 10 (API level 29) | No requirement | No requirement | No requirement |
| Android 9 (API level 28) | August 1, 2019 | November 1, 2019 | No requirement |
| application | Influence |
|---|---|
| new application | You will not be able to publish app bundles in the Play Console that do not meet the target API level requirements. |
| Apply updates | You will not be able to submit app bundles or APKs in the Play Console that do not meet the target API level requirements. |
| Existing applications | New users whose devices have a version of the Android OS higher than your app's target API level won't be able to get your app on Google Play. This means that these new users will not be able to discover or install your app from Google Play. Users who have previously installed the app from Google Play can still discover, reinstall, and use it. These existing users will still be able to use your app even if they switch to a new Android device. |

| Privacy changes | Affected apps | Mitigation strategies |
|---|---|---|
| Enforce Partitioned Storage Apps targeting Android 11 or higher will always be affected by Partitioned Storage behavior | Apps that target Android 11 or higher, and apps that target Android 10 and do not set requestLegacyExternalStorage to true to disable scoped storage | Update your app to use partitioned storage Learn more about partitioned storage changes |
| Single authorization allows users to grant temporary access to location, microphone, and camera | Apps running on Android 11 or higher that request location, microphone, or camera permissions | Before trying to access data protected by a permission, check that your app has the permission. Follow best practices for requesting permissions. |
| Automatically reset permissions If the user has not interacted with the app for several months on Android 11 or higher, the system automatically resets the app's sensitive permissions | Apps that target Android 11 or higher and do most of their work in the background | Ask users to prevent the system from resetting app permissionsLearn more about automatic reset permissions |
| Background location access Android 11 changes how users grant background location permissions to apps | Apps targeting Android 11 or higher that need to access location information in the background | Progressively requests permission to access location information in the foreground (coarse or precise) and in the background through multiple separate calls to the permission request method. If necessary, describe the benefits the user will gain by granting the permission. Learn more about accessing location in the background in Android 11 |
| Package visibility Android 11 changes how apps query and interact with other installed apps on the same device | Apps that target Android 11 or higher and interact with other installed apps on the device | Add the <queries> element to your app's manifest Learn more about package visibility |
| Foreground Services Android 11 changes the way foreground services access location information, camera and microphone related data | Apps running on Android 11 or higher that access location, camera, or microphone in a foreground service | For the front-end services that need to access the camera and microphone, declare camera and microphone front-end service types respectively. Note, however, that foreground services started while an app is running in the background typically do not have access to location, camera, or microphone.
