I'm implementing an Activity that uses a CameraSource and SurfaceView(to
show the camera's view) along with the new BarcodeDetector API and after
detection I'm trying to perform a finish() but it doesn't go back to the
prior Activity it just keeps running this one.
Here is a code snippet from my onCreate Activity, as you can see once I
detect a barcode I attempt to call finish but it doesn't seem to do
anything.
Is there something I have to shutdown prior to this?
I'm testing on a real device using Android 4.4.4
barcodeDetector = new BarcodeDetector.Builder(context).build();
barcodeDetector.setProcessor(new
FocusingProcessor<Barcode>(barcodeDetector, new Tracker<Barcode>()) {
@Override
public void receiveDetections(Detections<Barcode> detections) {
if(detections != null) {
SparseArray<Barcode> barcodes = detections.getDetectedItems();
if(barcodes != null && barcodes.size() > 0) {
int key = barcodes.keyAt(0);
Barcode bc = barcodes.get(key);
if(bc != null) {
barcode = bc.rawValue;
Intent resultData = new Intent();
resultData.putExtra("BARCODE", barcode);
setResult(Activity.RESULT_OK, resultData);
curActivity.finish();
}
}
}
}
}
@Override
public void release() {
super.release();
}
@Override
public int selectFocus(Detections<Barcode> arg0) {
return 0;
}
});
mCameraSource = new CameraSource.Builder(context, barcodeDetector)
.setFacing(CameraSource.CAMERA_FACING_BACK)
.build();
