  - supportsNativeImageCache
```
public boolean supportsNativeImageCache()
```
    Returns true if the platform supports a native image cache. The native image cache is different than just FileSystemStorage.hasCachesDir(). A native image cache is an image cache that the platform provides that is full transparent to Codename One with respect to how images are stored, and whether they are cached. Currently only the Javascript port supprts a native image cache.
    This is used by URLImage.createCachedImage(java.lang.String, java.lang.String, com.codename1.ui.Image, int) to determine if it should use a cached image, or to defer to its storage and filesystem methods.
    
    Returns:
    
    True on platforms that support a native image cache. Currently only Javascript.

```
public Rectangle getDisplaySafeArea(Rectangle rect)
```
    This method returns a rectangle defining the "safe" area of the display, which excludes areas on the screen that are covered by notches, task bars, rounded corners, etc.
    This feature was primarily added to deal with the task bar on the iPhone X, which is displayed on the screen near the bottom edge, and can interfere with components that are laid out at the bottom of the screen.
    
    Most platforms will simply return a Rectangle with bounds (0, 0, displayWidth, displayHeight). iPhone X will return a rectangle that excludes the notch, and task bar regions.
    
    Parameters:
    
    rect - Out parameter where safe bounds are set.

                           String targetOrigin)
```
    Posts a message to the window in a BrowserComponent. This is intended to be an abstraction of the Javascript postMessage() API.
    This is only overridden by the Javascript port to provide proper CORS handling. Other ports use the implementation in BrowserComponent.
    
    Web pages wishing to receive messages via this mechanism should register a "message" event listener. See Javascript postMessage() docs for more details about this.
    
    Parameters:
    
    browserComponent - The browser component peer.
    
    message - The message to send
    
    targetOrigin - The target origin for the message.

  - createNativeOverlay
```
public Object createNativeOverlay(Component cmp)
```
    Creates a native overlay for the given component. A native overlay is a native component that is always present over the given component. It can be used to help processing user events in a more native way. In the Javascript port, native overlays are used on TextFields, for example, so that users can tap on the text field and activate the keyboard. This was necessary because iOS doesn't allow us to programmatically activate the keyboard. Without a native overlay, the user would first have to tap the lightweight keyboard - upon which we create a native text field, and then the user would have to tap again to activate the keyboard. Using native overlays in that case yields better UX.
    
    When using native overlays, you will need to implement createNativeOverlay(com.codename1.ui.Component), hideNativeOverlay(com.codename1.ui.Component, java.lang.Object), and updateNativeOverlay(com.codename1.ui.Component, java.lang.Object). createNativeOverlay(com.codename1.ui.Component) is called in Component.initComponent() (i.e. when the component is added to the form). This is where you would create the native view and add it to the native view hierarchy above the CN1 canvas. updateNativeOverlay(com.codename1.ui.Component, java.lang.Object) is called in Component.laidOut() (i.e. when the component is resized/positioned). This is where you can reposition the native view or change its properties to be appropriate for the "occasion". hideNativeOverlay(com.codename1.ui.Component, java.lang.Object) is called in Component.deinitialize() (i.e. when the component is removed from the form). You should destroy the native view and remove it from the native view hierarchy here.
    
    Parameters:
    
    cmp - The component to create the overlay for.
    
    Returns:
    
    A native object. The object type/format is decided by the implementation.

    Deprecated. This method was never well-supported across platforms other than Android - and it will no longer work even in Android for SDK >= 17, unless o's class has the @JavascriptInterface annotation which would only be available if implemented inside a Native Interface. Don't use this.
    
    Allows exposing the given object to JavaScript code so the JavaScript code can invoke methods and access fields on the given object. Notice that on RIM devices which don't support reflection this object must implement the propriatery Scriptable interface http://www.blackberry.com/developers/docs/5.0.0api/net/rim/device/api/script/Scriptable.html
    
    Parameters:
    
    browserPeer - browser instance

    nativeImage - the native image
    
    name - the name/file name identifying the image
  - areMutableImagesFast
```
public boolean areMutableImagesFast()
```
    On most platforms it is quite fast to draw on a mutable image and then render that image, however some platforms have much slower mutable images in comparison to just drawing on the screen. These platforms should return false here and Codename One will try to use less mutable image related optimizations in transitions and other operations.

  - canGetSSLCertificates
```
public boolean canGetSSLCertificates()
```
    Checks if the platform supports getting SSL certificates.
    
    Returns:
    
    True if the platform supports SSL certificates.
  - checkSSLCertificatesRequiresCallbackFromNative
```
public boolean checkSSLCertificatesRequiresCallbackFromNative()
```
    SSL certificate checks must be performed via a callback from the native side, rather than explicitly checking as part of NetworkManager's connection flow. This is mainly for iOS POST requests. If we try to get the SSL certs explicitly, it forces the connection to be sent without a POST body. Hence we need to let iOS do the check on the native side, and callback into Java to run the checkSSLCertificates method of the request.
    
    Returns:
    
    True if the platform requires a native callback fo check SSL certificates
  - setConnectionId

                                    int bufferLen)
```
    This method is used to enable streaming of a HTTP request body without internal buffering, when the content length is not known in advance.

```
public void cancelLocalNotification(String notificationId)
```
  - setPreferredBackgroundFetchInterval
```
public void setPreferredBackgroundFetchInterval(int seconds)
```
    Sets the preferred time interval between background fetches. This is only a preferred interval and is not guaranteed. Some platforms, like iOS, maintain sovereign control over when and if background fetches will be allowed. This number is used only as a guideline.
    This method must be called in order to activate background fetch.>
    
    Note: If the platform doesn't support background fetch (i.e. isBackgroundFetchSupported() returns false, then this method does nothing.
    
    Parameters:
    
    seconds - The time interval in seconds.
    
    See Also:
    
    isBackgroundFetchSupported(), getPreferredBackgroundFetchInterval(), BackgroundFetch, com.codename1.ui.Display.setPreferredBackgroundFetchInterval(int)

```
public int getPreferredBackgroundFetchInterval()
```
    Gets the preferred time (in seconds) between background fetches.
    
    Returns:
    
    The time interval in seconds.
    
    See Also:

```
public boolean isBackgroundFetchSupported()
```
    Checks to see if the current platform supports background fetch.
    
    Returns:
    
    True if the current platform supports background fetch.

```
public boolean isGaussianBlurSupported()
```
  - isJailbrokenDevice
```
public boolean isJailbrokenDevice()
```
    Returns true if this device is jailbroken or rooted, false if not or unknown. Notice that this method isn't accurate and can't detect all jailbreak/rooting cases
    
    Returns:
    
    true if this device is jailbroken or rooted, false if not or unknown.
  - getProjectBuildHints
```
public Map<String,String> getProjectBuildHints()
```
    Returns the build hints for the simulator, this will only work in the debug environment and it's designed to allow extensions/API's to verify user settings/build hints exist
    
    Returns:
    
    map of the build hints that isn't modified without the codename1.arg. prefix
  - setProjectBuildHint
```
public void setProjectBuildHint(String key,
                                String value)
```
    Sets a build hint into the settings while overwriting any previous value. This will only work in the debug environment and it's designed to allow extensions/API's to verify user settings/build hints exist. Important: this will throw an exception outside of the simulator!
    
    Parameters:
    
    key - the build hint without the codename1.arg. prefix
    
    value - the value for the hint
  - canInstallOnHomescreen
```
public boolean canInstallOnHomescreen()
```
    Checks to see if you can prompt the user to install the app on their homescreen. This is only relevant for the Javascript port with PWAs. This is not a "static" property, as it only returns true if the app is in a state that allows you to prompt the user. E.g. if you have previously prompted the user and they have declined, then this will return false.
    Best practice is to use onCanInstallOnHomescreen(java.lang.Runnable) to be notified when you are allowed to prompt the user for installation. Then call promptInstallOnHomescreen() inside that method - or sometime after.
    
    Example
```
 
 onCanInstallOnHomescreen(()->{
      if (canInstallOnHomescreen()) {
           if (promptInstallOnHomescreen()) {
               // User accepted installation
           } else {
               // user rejected installation
           }
      }
 });
 
```
    https://developers.google.com/web/fundamentals/app-install-banners/
    Returns:
    
    True if you are able to prompt the user to install the app on their homescreen.
    
    See Also:
    
    promptInstallOnHomescreen(), onCanInstallOnHomescreen(java.lang.Runnable)
  - promptInstallOnHomescreen
```
public boolean promptInstallOnHomescreen()
```
    Prompts the user to install this app on their homescreen. This is only relevant in the javascript port.
    
    Returns:
    
    The result of the user prompt. true if the user accepts the installation, false if they reject it.
    
    See Also:
    
    canInstallOnHomescreen(), onCanInstallOnHomescreen(java.lang.Runnable)
  - onCanInstallOnHomescreen
```
public void onCanInstallOnHomescreen(Runnable r)
```
    A callback fired when you are allowed to prompt the user to install the app on their homescreen. Only relevant in the javascript port.
    
    Parameters:
    
    r - Runnable that will be run when/if you are permitted to prompt the user to install the app on their homescreen.
  - supportsNativeTextAreaVerticalAlignment
```
public boolean supportsNativeTextAreaVerticalAlignment()
```
    Checks whether the platform's native text areas support vertical alignment.
    
    Returns:

public void postMessage(MessageEvent message)
```
    Posts a message to the native platform.
    
    Parameters:
    
    message - The message.
    
    Since:
