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.

- * - *

Initiating a barcode scan

- * - *

To integrate, create an instance of {@code IntentIntegrator} and call {@link #initiateScan()} and wait - * for the result in your app.

- * - *

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.

- * - *

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:

- * - * 
{@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
- *   ...
- * }
- * }
- * - *

This is where you will handle a scan result.

- * - *

Second, just call this in response to a user action somewhere to begin the scan process:

- * - * 
{@code
- * IntentIntegrator integrator = new IntentIntegrator(yourActivity);
- * integrator.initiateScan();
- * }
- * - *

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.

- * - *

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.

- * - *

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.

- * - *

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.

- * - *

Sharing text via barcode

- * - *

To share text, encoded as a QR Code on-screen, similarly, see {@link #shareText(CharSequence)}.

- * - *

Some code, particularly download integration, was contributed from the Anobiit application.

- * - *

Enabling experimental barcode formats

- * - *

Some formats are not enabled by default even when scanning with {@link #ALL_CODE_TYPES}, such as - * PDF417. Use {@link #initiateScan(Collection)} with - * a collection containing the names of formats to scan for explicitly, like "PDF_417", to use such - * formats.
