For more information, see Version Support and Package Names in this document. There are a few distinct uses for the support libraries. Backward compatibility classes for earlier versions of the platform is just one of them. Here is a more complete list of ways you can use the support libraries in your app:. Upon discovering this, you may wonder if you should use the framework version of the API or the support library equivalent. Here are the guidelines for when you should use support library classes in place of Framework APIs:.
Support Library classes that provide a compatible implementation of platform API classes may not be able to provide the full set of functionality available in the latest release, due to the limitations of the host device platform version. In these cases, Support Library classes are designed to degrade gracefully, and may not provide the all the functionality or data of the current, platform API. For this reason, you should review the reference documentation for the library classes and methods you use, and thoroughly test on devices running the earliest version of the platform supported by your app.
Note: The support libraries do not provide equivalent classes and methods for each framework API. In some cases, you may need to wrap a framework method call with an explicit SDK version check and provide alternative code to handle methods not available on a device. For more information on using version checks in your code, see Supporting Different Platform Versions. Some of the Support Library packages have package names to indicate the minimum level of the API they originally supported, using a v notation, such as the support-v4 package.
Starting with Support Library version For this reason, when working with any recent release of the support library, you should not assume that the the v package notation indicates a minimum API support level.

GCM library has been moved to Google Play Services Now: android update sdk --no-ui -a --filter "extra-android-m2repository" Hope this helps someone. I wasted a LOT of time tracking this guy down. Well, you really helped me, i can't find the Android support Library item in SDK manager, only this command helps.
Thank you. Saved my life. I am on a mac, and the SDK manager won't show that an update is available for the support library. Edited post to reflect this. K 1, 15 15 silver badges 20 20 bronze badges. Padma Kumar Padma Kumar I dont even find Extras folder in android as you said. Like i said before i managed all others like Platforms,Platform tools and so by my self not by SDK manager.
FilmCreator that's y I asked you to make sure you location might be possible of you have different android SDK folders. But as i knew i never downloaded Support libraries by my notice atleast,so how come they r there??
Brain I can not see an option in SDK Manager to download android support libs, But I can see, there is a option to download android support repository. Issue Fixed a crash in OrientationHelper.

You can use this to add multiple buttons. This method will only succeed if it is given a valid id and the browser session is in the foreground.
Vector assets can be considerably smaller than image assets and should help reduce app size by reducing the amount of assets required to support multiple device screens.
This library is now a dependency of the v7 AppCompat library , allowing developers and AppCompat to easily use vector drawables. To keep referencing attribute IDs on API level 20 or lower, add the following appt flag to your build,gradle file: If you are building with Android Plugin for Gradle 1.

Added the following features to the MediaRouteControllerDialog class: Recognizes screen casting and provides a proper description. Supports various album art sizes and aspect ratios, and loads the art asynchronously. For example, the v7 appcompat and v7 gridlayout libraries include resources. If you are not sure if a library contains resources, check the Support Library Features page.
The following sections describe how to add a Support Library with or without resources to your application project. Using Eclipse. Using Android Studio. To add a Support Library with resources such as v7 appcompat for action bar to your application project:. Create a library project based on the support library code:. You now have a library project for your selected Support Library that you can use with one or more application projects. Note: If you are using the android-support-v7-mediarouter support library, you should note that it depends on the android-support-v7-appcompat library.
In order for the v7 mediarouter library to compile, you must import both library projects into your development workspace. Then follow the procedure above to add the v7 appcompat project as a library to the v7 mediarouter library project. Support Library classes that provide support for existing framework APIs typically have the same name as framework class but are located in the android. Caution: When using classes from the Support Library, be certain you import the class from the appropriate package.
For example, when applying the ActionBar class:. Note: After including the Support Library in your application project, we strongly recommend using the ProGuard tool to prepare your application APK for release. In addition to protecting your source code, the ProGuard tool also removes unused classes from any libraries you include in your application, which keeps the download size of your application as small as possible.
