Or do I need to create another folder called values-xlarge , values-normal? For example if you got values-v11 and values-v14 folders, then values-v11 and will be used on APIs 11, 12, 13 but on API 14 and higher, content of values-v14 will be used. It is not guaranteed or even assumed that every xlarge devices have to be running v14 API or that every ICS device features xlarge screen.

Before setting these attributes, make sure that you understand Google Play filters. The API Level expressed by an application will be compared to the API Level of a given Android system, which may vary among different Android devices. Despite its name, this element is used to specify the API Level, not the version number of the SDK software development kit or Android platform. The API Level is always a single integer. You cannot derive the API Level from its associated Android version number for example, it is not the same as the major version or the sum of the major and minor versions. Also read the document about Versioning Your Applications. If you do not declare this attribute, the system assumes a default value of '1', which indicates that your application is compatible with all versions of Android. If your application is not compatible with all versions for instance, it uses APIs introduced in API Level 3 and you have not declared the proper minSdkVersion , then when installed on a system with an API Level less than 3, the application will crash during runtime when attempting to access the unavailable APIs. For this reason, be certain to declare the appropriate API Level in the minSdkVersion attribute. 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. 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. 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. 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. In the case of re-validation after system update, this effectively removes your application from the device. To illustrate how this attribute can affect your application after system updates, consider the following example:. A user whose device is running Android 1. After a few weeks, the user receives an over-the-air system update to Android 2. The application functions as normal. However, some time later, the device receives another system update, this time to Android 2. The system prevents the application from being visible to the user, in effect removing it from the device. Declaring this attribute is not recommended. First, there is no need to set the attribute as means of blocking deployment of your application onto new versions of the Android platform as they are released. By design, new versions of the platform are fully backward-compatible. Your application should work properly on new versions, provided it uses only standard APIs and follows development best practices. Most devices on which your application is likely to be installed will receive periodic system updates over the air, so you should consider their effect on your application before setting this attribute. API Level is an integer value that uniquely identifies the framework API revision offered by a version of the Android platform. The Android platform provides a framework API that applications can use to interact with the underlying Android system. The framework API consists of:. Each successive version of the Android platform can include updates to the Android application framework API that it delivers. Updates to the framework API are designed so that the new API remains compatible with earlier versions of the API. That is, most changes in the API are additive and introduce new or replacement functionality. As parts of the API are upgraded, the older replaced parts are deprecated but are not removed, so that existing applications can still use them. In a very small number of cases, parts of the API may be modified or removed, although typically such changes are only needed to ensure API robustness and application or system security. All other API parts from earlier revisions are carried forward without modification. The framework API that an Android platform delivers is specified using an integer identifier called 'API Level'. Each Android platform version supports exactly one API Level, although support is implicit for all earlier API Levels down to API Level 1. The initial release of the Android platform provided API Level 1 and subsequent releases have incremented the API Level. The table below specifies the API Level supported by each version of the Android platform. For information about the relative numbers of devices that are running each version, see the Platform Versions dashboards page. The API Level identifier serves a key role in ensuring the best possible experience for users and application developers: Each Android platform version stores its API Level identifier internally, in the Android system itself. The element offers three key attributes:. The value of android: The system allows the installation to begin only if these conditions are met:. The principal reason that an application would declare an API Level in android: The system prevents such an outcome by not allowing the application to be installed if the lowest API Level it requires is higher than that of the platform version on the target device. For example, the android. If an application uses that API, it must declare a android: The application will then be installable on platforms such as Android 1. The sections below provide information related to API level that you should consider when developing your application. Because almost all changes to the framework API are additive, an Android application developed using any given version of the API as specified by its API Level is forward-compatible with later versions of the Android platform and higher API levels. The application should be able to run on all later versions of the Android platform, except in isolated cases where the application uses a part of the API that is later removed for some reason. Forward compatibility is important because many Android-powered devices receive over-the-air OTA system updates. The user may install your application and use it successfully, then later receive an OTA update to a new version of the Android platform. Once the update is installed, your application will run in a new run-time version of the environment, but one that has the API and system capabilities that your application depends on. In some cases, changes below the API, such those in the underlying system itself, may affect your application when it is run in the new environment. To help you test your application on various versions of the Android platform, the Android SDK includes multiple platforms that you can download. Each platform includes a compatible system image that you can run in an AVD, to test your application. Android applications are not necessarily backward compatible with versions of the Android platform older than the version against which they were compiled. Each new version of the Android platform can include new framework APIs, such as those that give applications access to new platform capabilities or replace existing API parts. The new APIs are accessible to applications when running on the new platform and, as mentioned above, also when running on later versions of the platform, as specified by API Level. Conversely, because earlier versions of the platform do not include the new APIs, applications that use the new APIs are unable to run on those platforms. Even among devices that receive OTA updates, some might lag and might not receive an update for a significant amount of time. When you are developing your application, you will need to choose the platform version against which you will compile the application. In general, you should compile your application against the lowest possible version of the platform that your application can support. You can determine the lowest possible platform version by compiling the application against successively lower build targets. After you determine the lowest version, you should create an AVD using the corresponding platform version and API Level and fully test your application. Make sure to declare a android: If you build an application that uses APIs or system features introduced in the latest platform version, you should set the android: This ensures that users will only be able to install your application if their devices are running a compatible version of the Android platform. In turn, this ensures that your application can function properly on their devices. If your application uses APIs introduced in the latest platform version but does not declare a android: To do so, create an AVD that uses the platform version required by your application. Additionally, to ensure forward-compatibility, you should run and test the application on all platforms that use a higher API Level than that used by your application. The Android SDK includes multiple platform versions that you can use, including the latest version, and provides an updater tool that you can use to download other platform versions as necessary. You can launch the SDK updater by executing android sdk. You can also simply double-click the android. To run your application against different platform versions in the emulator, create an AVD for each platform version that you want to test. For more information about AVDs, see Creating and Managing Virtual Devices. If you are using a physical device for testing, ensure that you know the API Level of the Android platform it runs. See the table at the top of this document for a list of platform versions and their API Levels. Reference documentation pages on the Android Developers site offer a 'Filter by API Level' control in the top-right area of each page. You can use the control to show documentation only for parts of the API that are actually accessible to your application, based on the API Level that it specifies in the android: To use filtering, select the checkbox to enable filtering, just below the page search box. Then set the 'Filter by API Level' control to the same API Level as specified by your application. Notice that APIs introduced in a later API Level are then grayed out and their content is masked, since they would not be accessible to your application. Filtering by API Level in the documentation does not provide a view of what is new or introduced in each API Level — it simply provides a way to view the entire API associated with a given API Level, while excluding API elements introduced in later API Levels. By default, API Level filtering is disabled, so that you can view the full framework API, regardless of API Level. Also note that the reference documentation for individual API elements specifies the API Level at which each element was introduced. The API Level for class members is specified in their detailed description headers, at the right margin. Except as noted, this content is licensed under Creative Commons Attribution 2.
