Summary
Inherited constants
|

|
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.
|

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.

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.

createWindowContext
open fun createWindowContext(
type: Int,
options: Bundle?
): Context
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..
| Parameters |
type |
Int: Value is android.view.WindowManager.LayoutParams#TYPE_ACCESSIBILITY_OVERLAY, android.view.WindowManager.LayoutParams#TYPE_APPLICATION, android.view.WindowManager.LayoutParams#TYPE_APPLICATION_ATTACHED_DIALOG, android.view.WindowManager.LayoutParams#TYPE_APPLICATION_MEDIA, android.view.WindowManager.LayoutParams#TYPE_APPLICATION_OVERLAY, android.view.WindowManager.LayoutParams#TYPE_APPLICATION_PANEL, android.view.WindowManager.LayoutParams#TYPE_APPLICATION_STARTING, android.view.WindowManager.LayoutParams#TYPE_APPLICATION_SUB_PANEL, android.view.WindowManager.LayoutParams#TYPE_BASE_APPLICATION, android.view.WindowManager.LayoutParams#TYPE_DRAWN_APPLICATION, android.view.WindowManager.LayoutParams#TYPE_INPUT_METHOD, android.view.WindowManager.LayoutParams#TYPE_INPUT_METHOD_DIALOG, android.view.WindowManager.LayoutParams.TYPE_KEYGUARD, android.view.WindowManager.LayoutParams#TYPE_KEYGUARD_DIALOG, android.view.WindowManager.LayoutParams#TYPE_PHONE, android.view.WindowManager.LayoutParams#TYPE_PRIORITY_PHONE, android.view.WindowManager.LayoutParams#TYPE_PRIVATE_PRESENTATION, android.view.WindowManager.LayoutParams#TYPE_SEARCH_BAR, android.view.WindowManager.LayoutParams#TYPE_STATUS_BAR, android.view.WindowManager.LayoutParams#TYPE_STATUS_BAR_PANEL, android.view.WindowManager.LayoutParams#TYPE_SYSTEM_ALERT, android.view.WindowManager.LayoutParams#TYPE_SYSTEM_DIALOG, android.view.WindowManager.LayoutParams#TYPE_SYSTEM_ERROR, android.view.WindowManager.LayoutParams#TYPE_SYSTEM_OVERLAY, android.view.WindowManager.LayoutParams#TYPE_TOAST, or android.view.WindowManager.LayoutParams#TYPE_WALLPAPER |

extraFlags |
Int: Always set to 0. |
options |
Bundle?: Additional options for how the Activity should be started. See android.content.Context#startActivity(Intent, Bundle) Context.startActivity(Intent, Bundle)} for more details. If options have also been supplied by the IntentSender, options given here will override any that conflict with those given by the IntentSender. This value may be null. |
startService
open fun startService(service: Intent!): ComponentName?
| Parameters |
service |
Intent!: Identifies the service to be started. The Intent must be fully explicit (supplying a component name). Additional values may be included in the Intent extras to supply arguments along with this specific start call. |
| Return |
ComponentName? |
If the service is being started or is already running, the ComponentName of the actual service that was started is returned; else if the service does not exist null is returned. |
| Exceptions |
java.lang.SecurityException |
If the caller does not have permission to access the service or the service can not be found. |
java.lang.IllegalStateException |
If the application is in a state where the service can not be started (such as not in the foreground in a state when services are allowed). |
stopService
open fun stopService(name: Intent!): Boolean
| Parameters |
service |
Description of the service to be stopped. The Intent must be either fully explicit (supplying a component name) or specify a specific package name it is targeted to. |
| Return |
Boolean |
If there is a service matching the given Intent that is already running, then it is stopped and true is returned; else false is returned. |
| Exceptions |
java.lang.SecurityException |
If the caller does not have permission to access the service or the service can not be found. |
java.lang.IllegalStateException |
If the application is in a state where the service can not be started (such as not in the foreground in a state when services are allowed). |
unbindService
open fun unbindService(conn: ServiceConnection): Unit
| Parameters |
conn |
ServiceConnection: The connection interface previously supplied to bindService(). This parameter must not be null. This value cannot be null. |
updateServiceGroup
open fun updateServiceGroup(
conn: ServiceConnection,
group: Int,
importance: Int
): Unit
| Parameters |
conn |
ServiceConnection: The connection interface previously supplied to bindService(). This parameter must not be null. This value cannot be null. |
group |
Int: A group to put this connection's process in. Upon calling here, this will override any previous group that was set for that process. The group tells the system about processes that are logically grouped together, so should be managed as one unit of importance (such as when being considered a recently used app). All processes in the same app with the same group are considered to be related. Supplying 0 reverts to the default behavior of not grouping. |
importance |
Int: Additional importance of the processes within a group. Upon calling here, this will override any previous importance that was set for that process. The most important process is 0, and higher values are successively less important. You can view this as describing how to order the processes in an array, with the processes at the end of the array being the least important. This value has no meaning besides indicating how processes should be ordered in that array one after the other. This provides a way to fine-tune the system's process killing, guiding it to kill processes at the end of the array first. |
Protected methods
attachBaseContext
protected open fun attachBaseContext(base: Context!): Unit
Set the base context for this ContextWrapper. All calls will then be delegated to the base context. Throws IllegalStateException if a base context has already been set.
| Parameters |
base |
Context!: The new base context for this wrapper. |
