/**
|
||||||
|
* <p>A utility class which helps ease integration with Barcode Scanner via {@link Intent}s. This is a simple
|
||||||
|
* way to invoke barcode scanning and receive the result, without any need to integrate, modify, or learn the
|
||||||
|
* project's source code.</p>
|
||||||
|
*
|
||||||
|
* <h2>Initiating a barcode scan</h2>
|
||||||
|
*
|
||||||
|
* <p>To integrate, create an instance of {@code IntentIntegrator} and call {@link #initiateScan()} and wait
|
||||||
|
* for the result in your app.</p>
|
||||||
|
*
|
||||||
|
* <p>It does require that the Barcode Scanner (or work-alike) application is installed. The
|
||||||
|
* {@link #initiateScan()} method will prompt the user to download the application, if needed.</p>
|
||||||
|
*
|
||||||
|
* <p>There are a few steps to using this integration. First, your {@link Activity} must implement
|
||||||
|
* the method {@link Activity#onActivityResult(int, int, Intent)} and include a line of code like this:</p>
|
||||||
|
*
|
||||||
|
* <pre>{@code
|
||||||
|
* public void onActivityResult(int requestCode, int resultCode, Intent intent) {
|
||||||
|
* IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
|
||||||
|
* if (scanResult != null) {
|
||||||
|
* // handle scan result
|
||||||
|
* }
|
||||||
|
* // else continue with any other code you need in the method
|
||||||
|
* ...
|
||||||
|
* }
|
||||||
|
* }</pre>
|
||||||
|
*
|
||||||
|
* <p>This is where you will handle a scan result.</p>
|
||||||
|
*
|
||||||
|
* <p>Second, just call this in response to a user action somewhere to begin the scan process:</p>
|
||||||
|
*
|
||||||
|
* <pre>{@code
|
||||||
|
* IntentIntegrator integrator = new IntentIntegrator(yourActivity);
|
||||||
|
* integrator.initiateScan();
|
||||||
|
* }</pre>
|
||||||
|
*
|
||||||
|
* <p>Note that {@link #initiateScan()} returns an {@link AlertDialog} which is non-null if the
|
||||||
|
* user was prompted to download the application. This lets the calling app potentially manage the dialog.
|
||||||
|
* In particular, ideally, the app dismisses the dialog if it's still active in its {@link Activity#onPause()}
|
||||||
|
* method.</p>
|
||||||
|
*
|
||||||
|
* <p>You can use {@link #setTitle(String)} to customize the title of this download prompt dialog (or, use
|
||||||
|
* {@link #setTitleByID(int)} to set the title by string resource ID.) Likewise, the prompt message, and
|
||||||
|
* yes/no button labels can be changed.</p>
|
||||||
|
*
|
||||||
|
* <p>Finally, you can use {@link #addExtra(String, Object)} to add more parameters to the Intent used
|
||||||
|
* to invoke the scanner. This can be used to set additional options not directly exposed by this
|
||||||
|
* simplified API.</p>
|
||||||
|
*
|
||||||
|
* <p>By default, this will only allow applications that are known to respond to this intent correctly
|
||||||
|
* do so. The apps that are allowed to response can be set with {@link #setTargetApplications(List)}.
|
||||||
|
* For example, set to {@link #TARGET_BARCODE_SCANNER_ONLY} to only target the Barcode Scanner app itself.</p>
|
||||||
|
*
|
||||||
|
* <h2>Sharing text via barcode</h2>
|
||||||
|
*
|
||||||
|
* <p>To share text, encoded as a QR Code on-screen, similarly, see {@link #shareText(CharSequence)}.</p>
|
||||||
|
*
|
||||||
|
* <p>Some code, particularly download integration, was contributed from the Anobiit application.</p>
|
||||||
|
*
|
||||||
|
* <h2>Enabling experimental barcode formats</h2>
|
||||||
|
*
|
||||||
|
* <p>Some formats are not enabled by default even when scanning with {@link #ALL_CODE_TYPES}, such as
|
||||||
|
* PDF417. Use {@link #initiateScan(java.util.Collection)} with
|
||||||
|
* a collection containing the names of formats to scan for explicitly, like "PDF_417", to use such
|
||||||
|
* formats.</p>
