Article last updated on :  March 14, 2021

The Android Webview doesn’t support file upload readily, We need additional codes to make the WebView support file upload. In this article, you can learn how to make your android webview app to handle html file input or file upload support. If this is hard for you, you can contact me and i will do it for you.

If you want a great android webview source code that has already functions for file upload, download, notifications and to easily create your android webview app. check out this page 

The code is a bit Complex , so you need carefully implement it to your webview activity, remember to place the code below the setWebviewClient method

Note: Starting from android Marshmallow, we need ask user permission to access storage and camera for uploading and capturing images.

The code for enabling file upload in webview

First, add these code above the OnCreate method of your webview Activity

    private static final int REQUEST_STORAGE = 1;
    private static final int REQUEST_LOCATION = 2;
    public ValueCallback<Uri> mUploadMessage;
    public static final int FILECHOOSER_RESULTCODE = 5173;

Then add this code in webChromeClient

public void openFileChooser(ValueCallback<Uri> uploadMsg) {
this.openFileChooser(uploadMsg, "*/*");

public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType) {
this.openFileChooser(uploadMsg, acceptType, null);

public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType, String capture) {
mUploadMessage = uploadMsg;
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
WebActivityDark.this.startActivityForResult(Intent.createChooser(i, "File Browser"),

public boolean onShowFileChooser(

WebView webView, ValueCallback<Uri[]> filePathCallback,
FileChooserParams fileChooserParams) {
if (mUMA != null) {
mUMA = filePathCallback;
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(WebActivityDark.this.getPackageManager()) != null) {
File photoFile = null;
try {
photoFile = createImageFile();
takePictureIntent.putExtra("PhotoPath", mCM);
} catch (IOException ex) {
Log.e(TAG, "Image file creation failed", ex);
if (photoFile != null) {
mCM = "file:" + photoFile.getAbsolutePath();
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));
} else {
takePictureIntent = null;

Intent contentSelectionIntent = new Intent(Intent.ACTION_GET_CONTENT);
Intent[] intentArray;
if (takePictureIntent != null) {
intentArray = new Intent[]{takePictureIntent};
} else {
intentArray = new Intent[0];

Intent chooserIntent = new Intent(Intent.ACTION_CHOOSER);
chooserIntent.putExtra(Intent.EXTRA_INTENT, contentSelectionIntent);
chooserIntent.putExtra(Intent.EXTRA_TITLE, "Image Chooser");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentArray);
startActivityForResult(chooserIntent, FCR);
return true;

protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
if (Build.VERSION.SDK_INT >= 21) {
Uri[] results = null;
//Check if response is positive
if (resultCode == Activity.RESULT_OK) {
if (requestCode == FCR) {
if (null == mUMA) {
if (intent == null) {
//Capture Photo if no image available
if (mCM != null) {
results = new Uri[]{Uri.parse(mCM)};
} else {
String dataString = intent.getDataString();
if (dataString != null) {
results = new Uri[]{Uri.parse(dataString)};
mUMA = null;
} else {
if (requestCode == FCR) {
if (null == mUM) return;
Uri result = intent == null || resultCode != RESULT_OK ? null : intent.getData();
mUM = null;

private class Callback extends WebViewClient {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(getApplicationContext(), "Failed loading! try reloading", Toast.LENGTH_SHORT).show();

// Create an image file
private File createImageFile() throws IOException {
@SuppressLint("SimpleDateFormat") String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "img_" + timeStamp + "_";
File storageDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
return File.createTempFile(imageFileName, ".jpg", storageDir);


This is it, if you place the code in your activity the right way, your app should now support file upload
