public class DMSDetectorView extends android.widget.LinearLayout implements android.view.View.OnTouchListener
DMSDetectorView is a drop in component that packages up media capture (video & audio), detection (image & audio) and Digimarc resolving into a single UI control.

As with all of DM SDK 3.0 components a license key is required to construct a DMSDetectorView object. The license key must be located in the application's manifest. To add your license key to the manifest, create an entry similar to the following inside the <application> section. 


 <meta-data android:name="com.digimarc.LicenseKey"
           android:value="license-key-goes-here">

The android:value="" entry can either contain your key string itself or it can contain an Android path to a string resource (i.e. "@string/license_key").

Many of DMSDetectorView's features may be configured via layout attributes. To use these you will need to add 'xmlns:custom="http://schemas.android.com/apk/res-auto"' to your layout if it is not already present.

Attributes:
   "custom:enableTapToFocus" - Enable/disable tap-to-focus behavior. See setTapFocusState(boolean).
   "custom:imageOnly" - Setting this to true will disable audio capture. See setImageOnly(boolean).
   "custom:showHelpPrompts" - If set this will show a rotating series of help messages on the screen.
   "custom:visualizerType" - Enables display of an audio visualizer. Possible values: none, microphone
   "custom:visualizerLocation" - Sets location of audio visualizer. Possible values: topLeft, topRight, bottomLeft, bottomRight
   "custom:visualizerBelowHelp" - If the visualizer is at the top of the screen and help text is also visible, should the visualizer appear below the text. Default: false
   "custom:showSpinner" - Set whether a spinner should be shown while payloads are being resolved. Default: true
   "custom:overlayType" - Set the type of UI overlay. Possible values: none, aiming_view, detect_region
Default: aiming_view
   "custom:showDetectionLocations" - Set whether image detection locations are drawn over the camera preview. Default: false

Deprecated Attributes:
   "custom:showDetectRegion" - Set whether the image detection region is highlighted on screen. See showDetectRegion(Context, boolean). Note that "custom:overlayType" will override this value.
   "custom:showAimingView" - Set whether aiming view should be inflated/added to the component. Note that "custom:overlayType" will override this value. Default: true
   "custom:aimingView" - Allows a custom aiming view to be used. See setAimingView(View, FrameLayout.LayoutParams).
   "custom:centerOffsetVertical" - Moves the location where the aiming view and spinner are shown up or down in the component. Value is a percentage of the screen height, and negative values move the view up. Supported value range is (-25, 25)

  • Method Details

    • setImageOnly

      public void setImageOnly(boolean imageOnly)
      Set this to true if audio detection is not needed. Note that to enable image only mode this method must be called before calling initialize(int, ReaderOptions, DISResultListener, DISErrorListener).
      Parameters:
      imageOnly - set to true to disable audio detections

    • initialize

      @RequiresPermission("android.permission.CAMERA") public boolean initialize(int readerSymbologies, @Nullable ReaderOptions readerOptions, @NonNull DISResultListener resultListener, @Nullable DISErrorListener errorListener)
      Initialize the view component. Note that the DMSDetectorView can only be initialized once. Calling this method a second time without first calling uninitialize() will cause an error to be raised via the error listener (if one is present).

      Note that this method does not support reading Digimarc Secure Digital Watermarks. In order to read these watermarks an application must use the initialize(int, ReaderOptions, DISResultListener, DISErrorListener, SecureWatermarkReadinessListener) method instead.

      Parameters:
      readerSymbologies - Bitmask of symbologies to search for. Bitmask values for both image and audio symbologies may be specified here, and the appropriate readers and media capture components will be configured to support it. Several pre-defined constants are available with support for major blocks of symbologies (All_Image_Symbologies, All_Audio_Symbologies & All_Symbologies). You can also build your own set of symbologies via the BaseReader.buildSymbologyMask(BaseReader.Symbology...) method. The available symbologies can be found in BaseReader.ImageSymbology and BaseReader.AudioSymbology. Note that if no audio symbologies are specified then audio capture will not be performed, and likewise for image symbologies and capture.
      readerOptions - Optional dictionary of reader options values. Possible options may be found in ReaderOptions.
      resultListener - Callback for SDK notifications. This may be either a DISResultListener or a DISResultListener object.
      errorListener - Optional listener for errors. If this is not supplied then error dialogs will be displayed instead.
      Returns:
      true for success. False will be returned if initialize is called after the component has already be initialized.

    • initialize

      @RequiresPermission("android.permission.CAMERA") public boolean initialize(int readerSymbologies, @Nullable ReaderOptions readerOptions, @NonNull DISResultListener resultListener, @Nullable DISErrorListener errorListener, @NonNull SecureWatermarkReadinessListener readinessListener)
      Initialize the view component. This version of the initialize() method supports reading Digimarc Secure Digital Watermarks. Note that the DMSDetectorView can only be initialized once. Calling this method a second time without first calling uninitialize() will cause an error to be raised via the error listener (if one is present).
      Parameters:
      readerSymbologies - Bitmask of symbologies to search for. Bitmask values for both image and audio symbologies may be specified here, and the appropriate readers and media capture components will be configured to support it. Several pre-defined constants are available with support for major blocks of symbologies (All_Image_Symbologies, All_Audio_Symbologies & All_Symbologies). You can also build your own set of symbologies via the BaseReader.buildSymbologyMask(BaseReader.Symbology...) method. The available symbologies can be found in BaseReader.ImageSymbology and BaseReader.AudioSymbology. Note that if no audio symbologies are specified then audio capture will not be performed, and likewise for image symbologies and capture.
      readerOptions - Optional dictionary of reader options values. Possible options may be found in ReaderOptions.
      resultListener - Callback for SDK notifications. This may be either a DISResultListener or a DISResultListener object.
      errorListener - Optional listener for errors. If this is not supplied then error dialogs will be displayed instead.
      readinessListener - Listener for secure watermark readiness status. Reading Digimarc Secure Digital Watermarks requires a readiness listener. Passing null for this parameter will disable secure watermark reading.
      Returns:
      true for success. False will be returned if initialize is called after the component has already be initialized.

    • setNotifyListener

      public void setNotifyListener(@Nullable DISNotifyListener listener)
      Set the camera notification listener
      Parameters:
      listener - The application's implementation of DISNotifyListener interface

    • start

      public boolean start()
      Starts the view's animations and background services, including audio detection (if enabled) and resolver notifications. This is typically invoked in an activity/fragment's onResume() event.

      Note that this method does not affect image detection. The camera preview stream and detection are started automatically when DMSDetectorView becomes visible. No further action is required by the developer. Use setDetectionEnabled(boolean) to manage detection independent of the view's lifecycle.

      Returns:
      true if successful

    • stop

      public void stop()
      Stops the view's animations and background services, including audio detection (if enabled) and resolver notifications. This method is intended to be invoked from an activity/fragment's onPause() event.

      Note that this method does not affect image detection. The camera preview stream and detection are stopped automatically when DMSDetectorView loses visibility. No further action is required by the developer. Use setDetectionEnabled(boolean) to manage detection independent of the view's lifecycle.

    • setLicenseKey

      public void setLicenseKey(@NonNull String key)
