Summary

Inherited constants

From class Context

`String`	`ACCESSIBILITY_SERVICE` Use with `getSystemService(java.lang.String)` to retrieve a `android.view.accessibility.AccessibilityManager` for giving the user feedback for UI events through the registered event listeners.
`String`	`ACCOUNT_SERVICE` Use with `getSystemService(java.lang.String)` to retrieve a `android.accounts.AccountManager` for receiving intents at a time of your choosing.
`String`	`ACTIVITY_SERVICE` Use with `getSystemService(java.lang.String)` to retrieve a `android.app.ActivityManager` for interacting with the global system state.
`String`	`ALARM_SERVICE` Use with `getSystemService(java.lang.String)` to retrieve a `android.app.AlarmManager` for receiving intents at a time of your choosing.
`String`	`APPWIDGET_SERVICE` Use with `getSystemService(java.lang.String)` to retrieve a `android.appwidget.AppWidgetManager` for accessing AppWidgets.
`String`	`APP_OPS_SERVICE` Use with `getSystemService(java.lang.String)` to retrieve a `android.app.AppOpsManager` for tracking application operations on the device.
`String`	`AUDIO_SERVICE` Use with `getSystemService(java.lang.String)` to retrieve a `android.media.AudioManager` for handling management of volume, ringer modes and audio routing.
`String`	`BATTERY_SERVICE` Use with `getSystemService(java.lang.String)` to retrieve a `android.os.BatteryManager` for managing battery state.
`Int`	`BIND_ABOVE_CLIENT` Flag for `bindService`: indicates that the client application binding to this service considers the service to be more important than the app itself. When set, the platform will try to have the out of memory killer kill the app before it kills the service it is bound to, though this is not guaranteed to be the case.
`Int`	`BIND_ADJUST_WITH_ACTIVITY` Flag for `bindService`: If binding from an activity, allow the target service's process importance to be raised based on whether the activity is visible to the user, regardless whether another flag is used to reduce the amount that the client process's overall importance is used to impact it.
`Int`	`BIND_ALLOW_OOM_MANAGEMENT` Flag for `bindService`: allow the process hosting the bound service to go through its normal memory management. It will be treated more like a running service, allowing the system to (temporarily) expunge the process if low on memory or for some other whim it may have, and being more aggressive about making it a candidate to be killed (and restarted) if running for a long time.
`Int`	`BIND_AUTO_CREATE` Flag for `bindService`: automatically create the service as long as the binding exists. Note that while this will create the service, its `android.app.Service#onStartCommand` method will still only be called due to an explicit call to `startService`. Even without that, though, this still provides you with access to the service object while the service is created. Note that prior to `android.os.Build.VERSION_CODES#ICE_CREAM_SANDWICH`, not supplying this flag would also impact how important the system consider's the target service's process to be. When set, the only way for it to be raised was by binding from a service in which case it will only be important when that activity is in the foreground. Now to achieve this behavior you must explicitly supply the new flag `BIND_ADJUST_WITH_ACTIVITY`. For compatibility, old applications that don't specify `BIND_AUTO_CREATE` will automatically have the flags `BIND_WAIVE_PRIORITY` and `BIND_ADJUST_WITH_ACTIVITY` set for them in order to achieve the same result.
`Int`	`BIND_DEBUG_UNBIND` Flag for `bindService`: include debugging help for mismatched calls to unbind. When this flag is set, the callstack of the following `unbindService` call is retained, to be printed if a later incorrect unbind call is made. Note that doing this requires retaining information about the binding that was made for the lifetime of the app, resulting in a leak -- this should only be used for debugging.
`Int`	`BIND_EXTERNAL_SERVICE` Flag for `bindService`: The service being bound is an `isolated`, `external` service. This binds the service into the calling application's package, rather than the package in which the service is declared. When using this flag, the code for the service being bound will execute under the calling application's package name and user ID. Because the service must be an isolated process, it will not have direct access to the application's data, though. The purpose of this flag is to allow applications to provide services that are attributed to the app using the service, rather than the application providing the service.
`Int`	`BIND_IMPORTANT` Flag for `bindService`: this service is very important to the client, so should be brought to the foreground process level when the client is. Normally a process can only be raised to the visibility level by a client, even if that client is in the foreground.
`Int`	`BIND_INCLUDE_CAPABILITIES` Flag for `bindService`: If binding from an app that has specific capabilities due to its foreground state such as an activity or foreground service, then this flag will allow the bound app to get the same capabilities, as long as it has the required permissions as well.
`Int`	`BIND_NOT_FOREGROUND` Flag for `bindService`: don't allow this binding to raise the target service's process to the foreground scheduling priority. It will still be raised to at least the same memory priority as the client (so that its process will not be killable in any situation where the client is not killable), but for CPU scheduling purposes it may be left in the background. This only has an impact in the situation where the binding client is a foreground process and the target service is in a background process.
`Int`	`BIND_NOT_PERCEPTIBLE` Flag for `bindService`: If binding from an app that is visible or user-perceptible, lower the target service's importance to below the perceptible level. This allows the system to (temporarily) expunge the bound process from memory to make room for more important user-perceptible processes.
`Int`	`BIND_WAIVE_PRIORITY` Flag for `bindService`: don't impact the scheduling or memory management priority of the target service's hosting process. Allows the service's process to be managed on the background LRU list just like a regular application process in the background.
`String`	`BIOMETRIC_SERVICE` Use with `getSystemService(java.lang.String)` to retrieve a `android.hardware.biometrics.BiometricManager` for handling biometric and PIN/pattern/password authentication.
`String`	`BLOB_STORE_SERVICE` Use with `getSystemService(java.lang.String)` to retrieve a for contributing and accessing data blobs from the blob store maintained by the system.
`String`	`BLUETOOTH_SERVICE` Use with `getSystemService(java.lang.String)` to retrieve a `android.bluetooth.BluetoothManager` for using Bluetooth.
`String`	`CAMERA_SERVICE` Use with `getSystemService(java.lang.String)` to retrieve a `android.hardware.camera2.CameraManager` for interacting with camera devices.
`String`	`CAPTIONING_SERVICE` Use with `getSystemService(java.lang.String)` to retrieve a `android.view.accessibility.CaptioningManager` for obtaining captioning properties and listening for changes in captioning preferences.
`String`	`CARRIER_CONFIG_SERVICE` Use with `getSystemService(java.lang.String)` to retrieve a `android.telephony.CarrierConfigManager` for reading carrier configuration values.
`String`	`CLIPBOARD_SERVICE` Use with `getSystemService(java.lang.String)` to retrieve a `android.content.ClipboardManager` for accessing and modifying the contents of the global clipboard.
`String`	`COMPANION_DEVICE_SERVICE` Use with `getSystemService(java.lang.String)` to retrieve a `android.companion.CompanionDeviceManager` for managing companion devices
`String`	`CONNECTIVITY_DIAGNOSTICS_SERVICE` Use with `getSystemService(java.lang.String)` to retrieve a for performing network connectivity diagnostics as well as receiving network connectivity information from the system.
`String`	`CONNECTIVITY_SERVICE` Use with `getSystemService(java.lang.String)` to retrieve a for handling management of network connections.
`String`	`CONSUMER_IR_SERVICE` Use with `getSystemService(java.lang.String)` to retrieve a `android.hardware.ConsumerIrManager` for transmitting infrared signals from the device.
`Int`	`CONTEXT_IGNORE_SECURITY` Flag for use with `createPackageContext`: ignore any security restrictions on the Context being requested, allowing it to always be loaded. For use with `CONTEXT_INCLUDE_CODE` to allow code to be loaded into a process even when it isn't safe to do so. Use with extreme care!
`Int`	`CONTEXT_INCLUDE_CODE` Flag for use with `createPackageContext`: include the application code with the context. This means loading code into the caller's process, so that `getClassLoader()` can be used to instantiate the application's classes. Setting this flags imposes security restrictions on what application context you can access; if the requested application can not be safely loaded into your process, java.lang.SecurityException will be thrown. If this flag is not set, there will be no restrictions on the packages that can be loaded, but `getClassLoader` will always return the default system class loader.
`Int`	`CONTEXT_RESTRICTED` Flag for use with `createPackageContext`: a restricted context may disable specific features. For instance, a View associated with a restricted context would ignore particular XML attributes.
`String`	`CROSS_PROFILE_APPS_SERVICE` Use with `getSystemService(java.lang.String)` to retrieve a `android.content.pm.CrossProfileApps` for cross profile operations.
`String`	`DEVICE_POLICY_SERVICE` Use with `getSystemService(java.lang.String)` to retrieve a `android.app.admin.DevicePolicyManager` for working with global device policy management.

`Int`	`MODE_ENABLE_WRITE_AHEAD_LOGGING` Database open flag: when set, the database is opened with write-ahead logging enabled by default.
`Int`	`MODE_MULTI_PROCESS` SharedPreference loading flag: when set, the file on disk will be checked for modification even if the shared preferences instance is already loaded in this process. This behavior is sometimes desired in cases where the application has multiple processes, all writing to the same SharedPreferences file. Generally there are better forms of communication between processes, though. This was the legacy (but undocumented) behavior in and before Gingerbread (Android 2.3) and this flag is implied when targeting such releases.

`Unit`	`clearWallpaper()`
`Context`	`createAttributionContext(attributionTag: String?)` Return a new Context object for the current Context but attribute to a different tag. In complex apps attribution tagging can be used to distinguish between separate logical parts.
`Context!`	`createConfigurationContext(overrideConfiguration: Configuration)`
`Context!`	`createDeviceProtectedStorageContext()`
`Context!`	`createDisplayContext(display: Display)`
`Context!`	`createPackageContext(packageName: String!, flags: Int)`
`Context`	`createWindowContext(type: Int, options: Bundle?)` Creates a Context for a non-activity window. A window context is a context that can be used to add non-activity windows, such as `android.view.WindowManager.LayoutParams#TYPE_APPLICATION_OVERLAY`. A window context must be created from a context that has an associated `Display`, such as `Activity` or a context created with `createDisplayContext(android.view.Display)`. The window context is created with the appropriate `Configuration` for the area of the display that the windows created with it can occupy; it must be used when `inflating` views, such that they can be inflated with proper `Resources`. Below is a sample code to add an application overlay window on the primary display: ... final DisplayManager dm = anyContext.getSystemService(DisplayManager.class); final Display primaryDisplay = dm.getDisplay(DEFAULT_DISPLAY); final Context windowContext = anyContext.createDisplayContext(primaryDisplay) .createWindowContext(TYPE_APPLICATION_OVERLAY, null); final View overlayView = Inflater.from(windowContext).inflate(someLayoutXml, null); // WindowManager.LayoutParams initialization ... mParams.type = TYPE_APPLICATION_OVERLAY; ... mWindowContext.getSystemService(WindowManager.class).addView(overlayView, mParams); This context's configuration and resources are adjusted to a display area where the windows with provided type will be added. Note that all windows associated with the same context will have an affinity and can only be moved together between different displays or areas on a display. If there is a need to add different window types, or non-associated windows, separate Contexts should be used. Creating a window context is an expensive operation. Misuse of this API may lead to a huge performance drop. The best practice is to use the same window context when possible. An approach is to create one window context with specific window type and display and use it everywhere it's needed..

`T`	`getSystemService(serviceClass: Class<T>)` Return the handle to a system-level service by class. Currently available classes are: `android.view.WindowManager`, `android.view.LayoutInflater`, `android.app.ActivityManager`, `android.os.PowerManager`, `android.app.AlarmManager`, `android.app.NotificationManager`, `android.app.KeyguardManager`, `android.location.LocationManager`, `android.app.SearchManager`, `android.os.Vibrator`, `android.net.ConnectivityManager`, `android.net.wifi.WifiManager`, `android.media.AudioManager`, `android.media.MediaRouter`, `android.telephony.TelephonyManager`, `android.telephony.SubscriptionManager`, `android.view.inputmethod.InputMethodManager`, `android.app.UiModeManager`, `android.app.DownloadManager`, `android.os.BatteryManager`, `android.app.job.JobScheduler`, `android.app.usage.NetworkStatsManager`. Note: System services obtained via this API may be closely associated with the Context in which they are obtained from. In general, do not share the service objects between various different contexts (Activities, Applications, Services, Providers, etc.) Note: Instant apps, for which `PackageManager#isInstantApp()` returns true, don't have access to the following system services: `DEVICE_POLICY_SERVICE`, `FINGERPRINT_SERVICE`, `KEYGUARD_SERVICE`, `SHORTCUT_SERVICE`, `USB_SERVICE`, `WALLPAPER_SERVICE`, `WIFI_P2P_SERVICE`, `WIFI_SERVICE`, `WIFI_AWARE_SERVICE`. For these services this method will return `null`. Generally, if you are running as an instant app you should always check whether the result of this method is `null`.
`CharSequence`	`getText(resId: Int)` Return a localized, styled CharSequence from the application's package's default string table.
`TypedArray`	`obtainStyledAttributes(attrs: IntArray)` Retrieve styled attribute information in this Context's theme. See `android.content.res.Resources.Theme#obtainStyledAttributes(int[])` for more information.
`TypedArray`	`obtainStyledAttributes(resid: Int, attrs: IntArray)` Retrieve styled attribute information in this Context's theme. See `android.content.res.Resources.Theme#obtainStyledAttributes(int, int[])` for more information.
`TypedArray`	`obtainStyledAttributes(set: AttributeSet?, attrs: IntArray)` Retrieve styled attribute information in this Context's theme. See `android.content.res.Resources.Theme#obtainStyledAttributes(AttributeSet, int[], int, int)` for more information.
`TypedArray`	`obtainStyledAttributes(set: AttributeSet?, attrs: IntArray, defStyleAttr: Int, defStyleRes: Int)` Retrieve styled attribute information in this Context's theme. See `android.content.res.Resources.Theme#obtainStyledAttributes(AttributeSet, int[], int, int)` for more information.
`Unit`	`registerComponentCallbacks(callback: ComponentCallbacks!)` Add a new `ComponentCallbacks` to the base application of the Context, which will be called at the same times as the ComponentCallbacks methods of activities and other components are called. Note that you must be sure to use `unregisterComponentCallbacks` when appropriate in the future; this will not be removed for you.
`Unit`	`sendBroadcastWithMultiplePermissions(intent: Intent, receiverPermissions: Array<String!>)` Broadcast the given intent to all interested BroadcastReceivers, allowing an array of required permissions to be enforced. This call is asynchronous; it returns immediately, and you will continue executing while the receivers are run. No results are propagated from receivers and receivers can not abort the broadcast. If you want to allow receivers to propagate results or abort the broadcast, you must send an ordered broadcast using `sendOrderedBroadcast(android.content.Intent,java.lang.String)`. See `BroadcastReceiver` for more information on Intent broadcasts.
`Unit`	`unregisterComponentCallbacks(callback: ComponentCallbacks!)` Remove a `ComponentCallbacks` object that was previously registered with `registerComponentCallbacks(android.content.ComponentCallbacks)`.

Public methods

setBaseContext

Added in API level 1

open fun setBaseContext(base: Context!): Unit

Change the base context for this ContextWrapper. All calls will then be delegated to the base context. Unlike ContextWrapper, the base context can be changed even after one is already set.

Parameters
`base`	Context!: The new base context for this wrapper.
