Family Link is Google's official parental control app. You will need to install the Google Family Link for parents on the parent phone and Google Family Link for children and teens on your child's phone. Use this method to block apps that have already been installed on your child's device. Sign in to Google Family Link. You will need to sign in to the parent's Google account on the parent's phone and the child's Google account on the child's phone.
Open Google Family Link on the parent phone. It has an icon that resembles a yellow, green, and blue icon. Tap your child's account. It has a profile image of your child. Tap More below "Installed Apps. Tap the app you want to block. This displays options for that app. Tap the goggle switch next to "Allow app. Method 2. In AGP 4. This change reflects the new Gradle behavior and supports configuration caching.
For more information on setting values in gradle. In previous releases, JDK 8 was bundled with Studio. When using the new bundled JDK to run Gradle, this may result in some incompatibility or impact JVM performance due to changes to the garbage collector. These issues are described below. Android Studio 4. For more information about Gradle compatibility, see Update Gradle.
To potentially improve build performance, we recommend testing your Gradle builds with the parallel garbage collector. In gradle. To measure build speed with different configurations, see Profile your build. This causes an increase in APK size, but it results in a smaller installation size on the device, and the download size is roughly the same.
This means that:. This means that it is no longer possible to write the following in Kotlin scripts for some collections that previously supported it:.
Android Gradle plugin 4. To export your native libraries, add the following to the android block of your library project's build. In this example, the mylibrary and myotherlibrary libraries from either your ndk-build or CMake external native build will be packaged in the AAR produced by your build, and each will export the headers from the specified directory to their dependents.
Kotlin uses custom metadata in Java class files to identify Kotlin language constructs. R8 now has support for maintaining and rewriting Kotlin metadata to fully support shrinking of Kotlin libraries and applications using kotlin-reflect. For more information, see Shrinking Kotlin libraries and applications using Kotlin reflection with R8 on Medium. When you build the debug version of your app using Android Gradle plugin 4.
The cleanBuildCache task and the android. The android. Starting with this release, fields from R classes are no longer kept by default , which may result in significant APK size savings for apps that enable code shrinking. This should not result in a behavior change unless you are accessing R classes by reflection, in which case it is necessary to add keep rules for those R classes. The experimental flag android. Set in the gradle. For library projects only, the BuildConfig.
Additionally, these values were discarded during manifest merging. In a future version of Android Gradle plugin, the versionName and versionCode properties will also be removed from the DSL for libraries.
You can set the path to your local NDK installation using the android. If you use this property together with the android. We've changed the behavior of how library unit tests are compiled and run. This configuration typically results in better testing. In some cases library unit tests that use data binding may encounter missing DataBindingComponent or BR classes. Those tests need to be ported to an instrumented test in the androidTest project, since compiling and running against those classes in a unit test may produce incorrect output.
The io. Gradle 6. To learn more, read the section about updating Gradle. This minor update supports compatibility with new default settings and features for package visibility in Android In previous versions of Android, it was possible to view a list of all apps installed on a device.
Starting with Android 11 API level 30 , by default apps have access to only a filtered list of installed packages. For more information on this new feature, see Package visibility in Android The Build Analyzer window helps you understand and diagnose issues with your build process, such as disabled optimizations and improperly configured tasks.
This feature is available when you use Android Studio 4. You can open the Build Analyzer window from Android Studio as follows:. The Build Analyzer window organizes possible build issues in a tree on the left.
You can inspect and click on each issue to investigate its details in the panel on the right. When Android Studio analyzes your build, it computes the set of tasks that determined the build's duration and provides a visualization to help you understand the impact of each of these tasks. You can also get details on warnings by expanding the Warnings node.
In Android Studio 4. This means that you can now include standard language APIs that were available only in recent Android releases such as java. The desugaring process rewrites your app's code to instead use this library at runtime. To enable support for these language APIs, include the following in your app module 's build. Note that you may also need to include the above code snippet in a library module 's build.
The library module's instrumented tests use these language APIs either directly or through the library module or its dependencies. You want to run lint on the library module in isolation. This is to help lint recognize valid usages of the language APIs and avoid reporting false warnings.
When new features are added, they will be disabled, by default. You can then use the buildFeatures block to enable only the features you want, and it helps you optimize the build performance for your project.
You can set the options for each module in the module-level build. Keep in mind, you can still use the buildFeatures block in the module-level build. In previous versions of the Android Gradle plugin, all feature modules could depend only on the app's base module. When using Android Gradle plugin 4. That is, a :video feature can depend on the :camera feature, which depends on the base module, as shown in the figure below.
Feature module :video depends on feature :camera , which depends on the base :app module. This means that when your app requests to download a feature module, the app also downloads other feature modules it depends on. For example, the :video module declares a dependency on :camera as follows:. When building your app using Android Gradle plugin 4.
When uploading your app, the Play Console inspects this metadata to provide you with the following benefits:. The data is compressed, encrypted by a Google Play signing key, and stored in the signing block of your release app. When you follow the configuration steps described below, Gradle automatically makes these native libraries available to use with your external native build system, such as CMake. Note that Gradle only makes these libraries available to your build; you must still configure your build scripts to use them.
Libraries are exported using the Prefab package format. Each dependency can expose at most one Prefab package, which comprises one or more modules. A Prefab module is a single library, which could be either a shared, static, or header-only library. Typically, the package name matches the Maven artifact name and the module name matches the library name, but this is not always true. Because you need to know the package and module name of the libraries, you might need to consult the dependency's documentation to determine what those names are.
CMake ndk-build. This value will be set automatically by Gradle when CMake is invoked, so if your build system modifies this variable, be sure to append rather than assign to it.
This command searches for config-file packages that match the given package name and version and exposes the targets it defines to be used in your build. For example, if your application defines libapp. When you build your project, your external native build system automatically links libapp.
For additional information, refer to the curl prefab sample. The behavior for app signing configurations in the signingConfig block has changed to the following:. These changes allow AGP to optimize builds by disabling the signing mechanism based on whether the user has explicitly enabled these flags.
Prior to this release, it was possible for v1Signing to be disabled even when explicitly enabled, which could be confusing. Android Gradle plugin 3. Or, are you worried that they are downloading apps inappropriate for their age? This will let you prevent your child from downloading unwanted apps on your device, as well as their own. The majority of apps have an age rating that helps determine which apps are most appropriate. You can block the downloads of apps that surpass a certain age by using parental controls within the Google Play Store.
Note: Apps on your phone that were downloaded before you set any parental controls are accessible, despite their age rating. You can set certain restrictions on their mobile phone or tablet usage, like app downloads, in-app purchases, and screen time. The solution is to hide the app. Certain smartphone brands have a built-in option to hide apps. You can also manually disable this feature by setting android.
