Share With Intents

On Android, it’s a declaration to the system that you would like to scan a barcode.

public void scanSomething() {
    // I need things done!  Do I have any volunteers?
    Intent intent = new Intent("com.google.zxing.client.android.SCAN");

    // This flag clears the called app from the activity stack, so users arrive in the expected
    // place next time this application is restarted.
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);

    intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
    startActivityForResult(intent, 0);
}
...
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
    if (requestCode == 0) {
        if (resultCode == RESULT_OK) {
            //  The Intents Fairy has delivered us some data!
            String contents = intent.getStringExtra("SCAN_RESULT");
            String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
            // Handle successful scan
        } else if (resultCode == RESULT_CANCELED) {
            // Handle cancel
        }
    }
}
