【移动开发】android:targetSdkVersion
android:targetSdkVersion
- An integer designating the API Level that the application targets. If not set, the default value equals that given to
minSdkVersion
.This attribute informs the system that you have tested against the target version and the system should not enable any compatibility behaviors to maintain your app‘s forward-compatibility with the target version. The application is still able to run on older versions (down to
minSdkVersion
).As Android evolves with each new version, some behaviors and even appearances might change. However, if the API level of the platform is higher than the version declared by your app‘s
targetSdkVersion
, the system may enable compatibility behaviors to ensure that your app continues to work the way you expect. You can disable such compatibility behaviors by specifyingtargetSdkVersion
to match the API level of the platform on which it‘s running. For example, setting this value to "11" or higher allows the system to apply a new default theme (Holo) to your app when running on Android 3.0 or higher and also disables screen compatibility mode when running on larger screens (because support for API level 11 implicitly supports larger screens).There are many compatibility behaviors that the system may enable based on the value you set for this attribute. Several of these behaviors are described by the corresponding platform versions in the
Build.VERSION_CODES
reference.To maintain your application along with each Android release, you should increase the value of this attribute to match the latest API level, then thoroughly test your application on the corresponding platform version.
