File Explorer not opening on webview, opening on regular mobile browser - android

So I've made a WebView for a friend's website for a project, the website includes a file's uploader, which when you click on it on a regular mobile/pc browser it opens the filesbrowser/explorer to look for the file to upload into the website.
But in the case of the WebView I've made, when I click the file uploader it just clicks without lunching the File Explorer of the phone so I can select files I wish to upload.
Any suggestions ? Thanks.

#Simo You have to set chrome client for your WebView. Please check below code
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setAllowFileAccess(true);
webView.getSettings().setAllowContentAccess(true);
webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
webView.setWebChromeClient(new WebChromeClient()
{
// For 3.0+ Devices (Start)
// onActivityResult attached before constructor
protected void openFileChooser(ValueCallback uploadMsg, String acceptType)
{
mUploadMessage = uploadMsg;
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("image/*");
startActivityForResult(Intent.createChooser(i, "File Browser"), FILECHOOSER_RESULTCODE);
}
// For Lollipop 5.0+ Devices
public boolean onShowFileChooser(WebView mWebView, ValueCallback<Uri[]> filePathCallback, WebChromeClient.FileChooserParams fileChooserParams)
{
if (uploadMessage != null) {
uploadMessage.onReceiveValue(null);
uploadMessage = null;
}
uploadMessage = filePathCallback;
Intent intent = fileChooserParams.createIntent();
try
{
startActivityForResult(intent, REQUEST_SELECT_FILE);
} catch (ActivityNotFoundException e)
{
uploadMessage = null;
Toast.makeText(getApplicationContext(), "Cannot Open File Chooser", Toast.LENGTH_LONG).show();
return false;
}
return true;
}
//For Android 4.1 only
protected void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType, String capture)
{
mUploadMessage = uploadMsg;
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("image/*");
startActivityForResult(Intent.createChooser(intent, "File Browser"), FILECHOOSER_RESULTCODE);
}
protected void openFileChooser(ValueCallback<Uri> uploadMsg)
{
mUploadMessage = uploadMsg;
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("image/*");
startActivityForResult(Intent.createChooser(i, "File Chooser"), FILECHOOSER_RESULTCODE);
}
});
Also override onActivityResult like below
#Override
public void onActivityResult(int requestCode, int resultCode, Intent intent)
{
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
{
if (requestCode == REQUEST_SELECT_FILE)
{
if (uploadMessage == null)
return;
uploadMessage.onReceiveValue(WebChromeClient.FileChooserParams.parseResult(resultCode, intent));
uploadMessage = null;
}
}
else if (requestCode == FILECHOOSER_RESULTCODE)
{
if (null == mUploadMessage)
return;
// Use MainActivity.RESULT_OK if you're implementing WebView inside Fragment
// Use RESULT_OK only if you're implementing WebView inside an Activity
Uri result = intent == null || resultCode != MainActivity.RESULT_OK ? null : intent.getData();
mUploadMessage.onReceiveValue(result);
mUploadMessage = null;
}
else
Toast.makeText(getApplicationContext(), "Failed to Upload Image", Toast.LENGTH_LONG).show();
}

Android Webview Duplicate Files when Selecting Image

I'm having a problem with uploading files on android webview which occurs when I select a file or camera to select then a CAPUTURE_OOOOOOOO.jpg file is formed which should only be formed when I manage to take a photo and take the image into the selected image file, here's the code with kotlin
myWebView.webChromeClient = object : WebChromeClient() {
override fun onShowFileChooser(webView: WebView, filePathCallback: ValueCallback<Array<Uri>>, fileChooserParams: FileChooserParams):Boolean {
chooserCallback = filePathCallback
val fileCamera = File(
Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES
), "CAPTURE_" + System.currentTimeMillis().toString() + ".jpg"
)
chooserCamera = Uri.fromFile(fileCamera)
val captureIntent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
captureIntent.putExtra(MediaStore.EXTRA_OUTPUT, chooserCamera)
val imageIntent = Intent(Intent.ACTION_GET_CONTENT)
imageIntent.addCategory(Intent.CATEGORY_OPENABLE)
imageIntent.type = "image/*"
val chooserIntent = Intent.createChooser(imageIntent, "Select Image")
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, arrayOf(captureIntent))
startActivityForResult(chooserIntent, requestChooser)
return true
}
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (requestCode == requestChooser) {
if (resultCode == Activity.RESULT_OK) {
Log.v("chooserCamera", data?.dataString.toString())
Log.v("dataString", data?.dataString.toString())
val result: Uri = if (data?.dataString == null) chooserCamera as Uri else data.data as Uri
chooserCallback?.onReceiveValue(arrayOf(result))
chooserCallback = null
}
if (resultCode == Activity.RESULT_CANCELED) {
Toast.makeText(applicationContext, "No Image", Toast.LENGTH_SHORT).show()
chooserCallback?.onReceiveValue(null)
chooserCallback = null
}
}
}
the CAPUTURE_OOOOOOOO.jpg file should only be formed when I take a photo with the camera and select it, not when I press the choose button so there is a duplication of files in this process, thank you

How can I upload multiple images from gallery?

I can choose single image from gallery but can't choose multiple images.
I google information about that and found add EXTRA_ALLOW_MULTIPLE to putExtra, but it doesn't work for me. Can anyone help me?
My problem is file upload on webview. I am targeting at os6, os7 or os8.
my code :
mWebview.setWebChromeClient(new WebChromeClient() {
protected void openFileChooser(ValueCallback uploadMsg, String acceptType) {
mUploadMessage = uploadMsg;
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("image/*");
i.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
i.setAction(Intent.ACTION_PICK);
startActivityForResult(Intent.createChooser(i, "File Browser"), FILECHOOSER_RESULTCODE);
}
update

Try this. Working in all versions.
use image picker
ImagePicker.create(UploadPhotosActivity.this)
.showCamera(false)
.limit(2) // set your limit here
.imageTitle(getString(R.string.select_image))
.folderTitle(getString(R.string.folder))
.theme(R.style.ImagePickerTheme)
.start(RC_CODE_PICKER);
add these to your dependency
compile 'com.github.esafirm.android-image-picker:imagepicker:1.5.0'
compile 'com.github.esafirm.android-image-picker:rximagepicker:1.5.0'
Edit your code i.e. Remove:
i.setAction(Intent.ACTION_PICK);
Follow below code :
Intent intent = new Intent();
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"), 1);

I have a splash before ... but what I do not get all white if the page has not yet been charged. I want to show a shipment and then only when you are 100% loaded, display the page.
Thanks
Put your webview inside framelayout and putan imageview also in framelayout. While page is loading show the imageView(animate if you want).

FilePicker from android webview working only once

I need to pick an image from webview and upload it onto server. The code works, but if I press back without picking anything, next time the control does not goes in onShowFileChooser.
I have checked the same on android browser and it works there, so there has to be something that I am missing.
Below is the code:
web.setWebChromeClient(new BizzerClient());
web.setWebViewClient(new WebViewClient(){
//=========================================
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url){
if(url.contains(Domain) && !url.startsWith(SMS)){
//== if url is of same site and not related to sms, do nothing
}else{
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
return true;
}
return false;
}
});
//=========================================
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
if(requestCode==FileChooser){
Uri result = intent == null || resultCode != RESULT_OK ?null:Uri.parse(intent.getDataString());
if(result==null) return;
if(fPathCallback!=null){
fPathCallback.onReceiveValue(new Uri[]{result});
fPathCallback = null;
}else{
upload.onReceiveValue(result);
upload = null;
}
}
}
//=====================================================
class BizzerClient extends WebChromeClient{
//=========================================
public void openFileChooser(ValueCallback<Uri> uploadMsg) {
upload = uploadMsg;
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("image/*");
startActivityForResult(Intent.createChooser(i,"File Chooser"), FileChooser);
}
//=========================================
//== For Android 3.0+
public void openFileChooser( ValueCallback uploadMsg, String acceptType ) {
upload = uploadMsg;
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("*/*");
startActivityForResult(Intent.createChooser(i, "File Browser"),FileChooser);
}
//=========================================
//== For Android 4.1
public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType, String capture){
upload = uploadMsg;
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("image/*");
startActivityForResult( Intent.createChooser( i, "File Chooser" ), FileChooser );
}
//=========================================
public boolean onShowFileChooser(WebView webView, ValueCallback<Uri[]> filePathCallback,WebChromeClient.FileChooserParams fileChooserParams) {
fPathCallback = filePathCallback;
Toast.makeText(getApplicationContext(), "A", Toast.LENGTH_SHORT).show();
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("image/*");
startActivityForResult(Intent.createChooser(i,"File Chooser"), FileChooser);
return true;
}
}
Does anyone know how to fix this?
My workmate has exactly same issue, he has fixed it by
upload.onReceiveValue(null)
I had the same issue, the problem was I was expecting an OnActivityResult, but when you press the back button, this was not triggered.
The solution was implementing on onResume the following code, to tell the callback the answer was empty and being able to reuse it:
#Override
protected void onResume() {
super.onResume();
if (fPathCallback == null)
return;
fPathCallback.onReceiveValue(new Uri[]{});
fPathCallback = null;
}
