Improve some error messages. Fix fastboot flashall on Nexus 7. Fix crash when using adb -H. Added a comment to explain that. When creating an AVD with avdmanager, it is no longer necessary to specify --tag if the package specified by --package only contains a single image as is the case for all images currently distributed by Google.
Add --fastdeploy option to adb install, for incremental updates to APKs while developing. Available Packages: SDK Tools Contains tools for debugging and testing, plus other utilities that are required to develop an app. If you've just installed the SDK starter package, then you already have the latest version of this package.
Make sure you keep this up to date. SDK Platform-tools Contains platform-dependent tools for developing and debugging your application. These tools support the latest features of the Android platform and are typically updated only when a new platform becomes available. These tools are always backward compatible with older platforms, but you must be sure that you have the latest version of these tools when you install a new SDK platform.
It includes an android. Like other uses in this Stackoverflow question:. Can't build Java project on OSX yosemite. We were unfortunate enough to have to use AUSKey some ancient dinosaur Java authentication key system used by Australian Government to authenticate our computer before we can log into Australian business portal website. My speculation is tools.
If you're worried, instead of deleting this file, you can make a backup of the whole folder and save it somewhere just in case you can't login to Australian Business Portal again. Please also notice if you came across an error about Java 8 language features requires Jack enabled , you need to add the following to your gradle file as shown above :.
I am developing an Android App in Android Studio. Not quite sure what went wrong. I was successfully building a few days ago. Any help would be great. I encountered the same error. All support libraries and build tools updated. Was still facing the same issue. I am using Android annotations in my project. I added a new View.. When I run the project, instead of indicating the view already exists, I was receiving the above error.
I faced a similar problem, but I had to set manually the jdk folder on program files, so I recommend to everybody specially the ones that are upgrading to java 8, to point directly in the project settings of the android studio, either using the embed option or choosing the folder. But changing the compileSdkVersion alone does not actually change the behaviour of the app that you created. So how does the Android system know if it can use new functionalities with your app or not?
If the user runs your app on a device with an android version that is higher than the targetSdkVersion defined in your app, for new android features, the system may introduce some backwards-compatibility behaviour to ensure your app still looks and works in a way that you designed it.
In Android 12 the appearance of custom notifications was changed. Previously they could use the whole notification area, but in Android 12 system applies the standard template to all custom notifications so they look more consistent. Only after you update the target SDK version to 31 the new notification appearance will be used.
No, not all changes that are introduced in new Android versions are targeted and use these backwards-compatibility mechanisms. For each Android version release, in documentation, you can see that changes are split into two groups:. An example of the latter may be the introduction of one time permissions in Android When the device uses Android version 11 or higher and the app asks for location permission, the user can grant temporary access to that data and the app has to handle that case properly no matter if it targets SDK version 30 or not.
Even if the compileSdkVersion and targetSdkVersion have completely different meanings they are obviously not independent. Adds support for encapsulation of user interface and functionality with fragments , enabling applications to provide layouts that adjust between small and large-screen devices. This module has dependencies on compat , core-utils , core-ui , and media-compat. Note: The v13 support library provides a FragmentCompat class. The v4 Fragment class is a standalone class that provides bugfixes which were added in later platform versions, whereas the v13 FragmentCompat class provides compatibility shims for the framework implementation of the Fragment class.
Apps that reference more than methods are required to use multidex configurations. These libraries provide specific feature sets and can be included in your application independently from each other. Note: The appcompat library has migrated into the AndroidX library, which is an Android Jetpack component. See it in use in the Sunflower demo app. This library adds support for the Action Bar user interface design pattern. This library includes support for material design user interface implementations.
This library adds support for the CardView widget, which lets you show information inside cards that have a consistent look on any app. These cards are useful for material design implementations, and are used extensively in layouts for TV apps. After you download the Android Support Libraries, this library adds support for the GridLayout class, which allows you to arrange user interface elements using a grid of rectangular cells. For detailed information about the v7 gridlayout library APIs, see the android.
In general, the APIs in the v7 mediarouter library provide a means of controlling the routing of media channels and streams from the current device to external screens, speakers, and other destination devices. The library includes APIs for publishing app-specific media route providers, for discovering and selecting destination devices, for checking media status, and more. For detailed information about the v7 mediarouter library APIs, see the android.
At this time, we recommend using the library only in connection with Google Cast. The v7 palette support library includes the Palette class, which lets you extract prominent colors from an image. For example, a music app could use a Palette object to extract the major colors from an album cover, and use those colors to build a color-coordinated song title card.
The recyclerview library adds the RecyclerView class.
