Known direct subclasses

Activity

Activity An activity is a single, focused thing that the user can do.

Known indirect subclasses

AccountAuthenticatorActivity, ActivityGroup, AliasActivity, ExpandableListActivity, LauncherActivity, ListActivity, NativeActivity, PreferenceActivity, TabActivity

AccountAuthenticatorActivity	This class was deprecated in API level 30. Applications should extend Activity themselves. This class is not compatible with AppCompat, and the functionality it provides is not complex.
ActivityGroup	This class was deprecated in API level 13. Use the new `Fragment` and `FragmentManager` APIs instead; these are also available on older platforms through the Android compatibility package.
AliasActivity	This class was deprecated in API level 30. Use `<activity-alias>` or subclass Activity directly.
ExpandableListActivity	This class was deprecated in API level 30. Use `RecyclerView` or use `ExpandableListView` directly
LauncherActivity	This class was deprecated in API level 30. Applications can implement this UI themselves using `RecyclerView` and `PackageManager.queryIntentActivities(Intent, int)`
ListActivity	This class was deprecated in API level 30. Use `ListFragment` or `RecyclerView` to implement your Activity instead.
NativeActivity	Convenience for implementing an activity that will be implemented purely in native code.
PreferenceActivity	This class was deprecated in API level 29. Use the AndroidX Preference Library for consistent behavior across all devices. For more information on using the AndroidX Preference Library see Settings.
TabActivity	This class was deprecated in API level 13. New applications should use Fragments instead of this class; to continue to run on older devices, you can use the v4 support library which provides a version of the Fragment API that is compatible down to `Build.VERSION_CODES.DONUT`.

A context wrapper that allows you to modify or replace the theme of the wrapped context.

Public constructors

ContextThemeWrapper

Added in API level 1

public ContextThemeWrapper ()

Creates a new context wrapper with no theme and no base context.

Note: A base context must be attached using attachBaseContext(android.content.Context) before calling any other method on the newly constructed context wrapper.

ContextThemeWrapper

Added in API level 1

public ContextThemeWrapper (Context base, 
                int themeResId)

Creates a new context wrapper with the specified theme.

The specified theme will be applied on top of the base context's theme. Any attributes not explicitly defined in the theme identified by themeResId will retain their original values.

Parameters
`base`	`Context`: the base context
`themeResId`	`int`: the resource ID of the theme to be applied on top of the base context's theme

ContextThemeWrapper

Added in API level 23

public ContextThemeWrapper (Context base, 
                Resources.Theme theme)

Creates a new context wrapper with the specified theme.

Unlike ContextThemeWrapper(android.content.Context, int), the theme passed to this constructor will completely replace the base context's theme.

Parameters
`base`	`Context`: the base context
`theme`	`Resources.Theme`: the theme against which resources should be inflated

Public methods

applyOverrideConfiguration

Added in API level 17

public void applyOverrideConfiguration (Configuration overrideConfiguration)

Call to set an "override configuration" on this context -- this is a configuration that replies one or more values of the standard configuration that is applied to the context. See Context#createConfigurationContext(Configuration) for more information.

This method can only be called once, and must be called before any calls to getResources() or getAssets() are made.

Parameters
`overrideConfiguration`	`Configuration`

getAssets

Added in API level 1

public AssetManager getAssets ()

Returns an AssetManager instance for the application's package.

Note: Implementations of this method should return an AssetManager instance that is consistent with the Resources instance returned by getResources(). For example, they should share the same Configuration object.

Returns
`AssetManager`	an AssetManager instance for the application's package

getResources

Added in API level 1

public Resources getResources ()

Returns a Resources instance for the application's package.

Note: Implementations of this method should return a Resources instance that is consistent with the AssetManager instance returned by getAssets(). For example, they should share the same Configuration object.

Returns
`Resources`	a Resources instance for the application's package

getSystemService

Added in API level 1

public Object getSystemService (String name)

Return the handle to a system-level service by name. The class of the returned object varies by the requested name. Currently available names are:

WINDOW_SERVICE ("window"): The top-level window manager in which you can place custom windows. The returned object is a WindowManager. Must only be obtained from a visual context such as Activity or a Context created with createWindowContext(int, android.os.Bundle), which are adjusted to the configuration and visual bounds of an area on screen.
LAYOUT_INFLATER_SERVICE ("layout_inflater"): A LayoutInflater for inflating layout resources in this context. Must only be obtained from a visual context such as Activity or a Context created with createWindowContext(int, android.os.Bundle), which are adjusted to the configuration and visual bounds of an area on screen.
ACTIVITY_SERVICE ("activity"): A ActivityManager for interacting with the global activity state of the system.
WALLPAPER_SERVICE ("wallpaper"): A WallpaperService for accessing wallpapers in this context. Must only be obtained from a visual context such as Activity or a Context created with createWindowContext(int, android.os.Bundle), which are adjusted to the configuration and visual bounds of an area on screen.
POWER_SERVICE ("power"): A PowerManager for controlling power management.
ALARM_SERVICE ("alarm"): A AlarmManager for receiving intents at the time of your choosing.
NOTIFICATION_SERVICE ("notification"): A NotificationManager for informing the user of background events.
KEYGUARD_SERVICE ("keyguard"): A KeyguardManager for controlling keyguard.
LOCATION_SERVICE ("location"): A LocationManager for controlling location (e.g., GPS) updates.
SEARCH_SERVICE ("search"): A SearchManager for handling search.
VIBRATOR_MANAGER_SERVICE ("vibrator_manager"): A VibratorManager for accessing the device vibrators, interacting with individual ones and playing synchronized effects on multiple vibrators.
VIBRATOR_SERVICE ("vibrator"): A Vibrator for interacting with the vibrator hardware.
CONNECTIVITY_SERVICE ("connectivity"): A ConnectivityManager for handling management of network connections.
IPSEC_SERVICE ("ipsec"): A IpSecManager for managing IPSec on sockets and networks.
WIFI_SERVICE ("wifi"): A WifiManager for management of Wi-Fi connectivity. On releases before Android 7, it should only be obtained from an application context, and not from any other derived context to avoid memory leaks within the calling process.
WIFI_AWARE_SERVICE ("wifiaware"): A WifiAwareManager for management of Wi-Fi Aware discovery and connectivity.
WIFI_P2P_SERVICE ("wifip2p"): A WifiP2pManager for management of Wi-Fi Direct connectivity.
INPUT_METHOD_SERVICE ("input_method"): An InputMethodManager for management of input methods.
UI_MODE_SERVICE ("uimode"): An UiModeManager for controlling UI modes.
DOWNLOAD_SERVICE ("download"): A DownloadManager for requesting HTTP downloads
BATTERY_SERVICE ("batterymanager"): A BatteryManager for managing battery state
JOB_SCHEDULER_SERVICE ("taskmanager"): A JobScheduler for managing scheduled tasks
NETWORK_STATS_SERVICE ("netstats"): A NetworkStatsManager for querying network usage statistics.
HARDWARE_PROPERTIES_SERVICE ("hardware_properties"): A HardwarePropertiesManager for accessing hardware properties.
DOMAIN_VERIFICATION_SERVICE ("domain_verification"): A DomainVerificationManager for accessing web domain approval state.
DISPLAY_HASH_SERVICE ("display_hash"): A DisplayHashManager for management of display hashes.

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.

Note: When implementing this method, keep in mind that new services can be added on newer Android releases, so if you're looking for just the explicit names mentioned above, make sure to return null when you don't recognize the name — if you throw a RuntimeException exception instead, your app might break on new Android releases.
