Getting Started

Installation

1. Clone the repository:

     git clone https://github.com/Bhavyansh03-tech/Document_scanner.git

2. Open the project in Android Studio.

3. Build the project and run it on an emulator or a physical device.

Setup

1. Dependencies Add the following dependencies to your build.gradle file:

  implementation 'com.google.mlkit:document-scanner:16.0.0-beta1'
  implementation 'io.coil-kt:coil-compose:2.7.0'

2. Usage Here's the code to implement the document scanner:

val options = GmsDocumentScannerOptions.Builder()
    .setGalleryImportAllowed(false)
    .setResultFormats(
        GmsDocumentScannerOptions.RESULT_FORMAT_JPEG,
        GmsDocumentScannerOptions.RESULT_FORMAT_PDF
    )
    .setPageLimit(2)
    .setScannerMode(SCANNER_MODE_FULL)
    .build()

var selectedImageUri by remember {
    mutableStateOf(Uri.EMPTY)
}

val scanner = GmsDocumentScanning.getClient(options)

val scannerLauncher = rememberLauncherForActivityResult(
    contract = ActivityResultContracts.StartIntentSenderForResult()
) { result ->
    if (result.resultCode == RESULT_OK) {
        val scannerResult =
            GmsDocumentScanningResult.fromActivityResultIntent(result.data)

        scannerResult?.pages?.let { pages ->
            for (page in pages) {
                selectedImageUri = pages[0].imageUri
            }
        }
    }
}

// Context
val context = LocalContext.current as Activity

Column(
    modifier = Modifier.fillMaxSize(),
    verticalArrangement = Arrangement.Center,
    horizontalAlignment = Alignment.CenterHorizontally
) {
    AsyncImage(
        model = selectedImageUri,
        contentDescription = null,
        contentScale = ContentScale.Crop, modifier = Modifier.size(200.dp)
    )

    Spacer(modifier = Modifier.height(10.dp))

     Button(onClick = {
         scanner.getStartScanIntent(context)
             .addOnSuccessListener { intentSender ->
                 scannerLauncher.launch(
                     IntentSenderRequest
                         .Builder(intentSender)
                         .build()
                 )
             }
     }) {
         Text(text = "Start Scanning")
     }
}
