I have been working hard trying to upload files from a webview. I tried many solutions but none worked.
http://m0s-programming.blogspot.tw/2011/02/file-upload-in-through-webview-on.html
filechooser works fine in a desktop browser like chrome when I click the button and the browser opens a dialog box where I can choose a file to upload.
When I use my cellphone to test the program and I click choose file the Dialog box has no reaction
Can someone help me? Thanks
Refer this Documentation :

public boolean onShowFileChooser(
WebView webView, ValueCallback<Uri[]> filePathCallback,
WebChromeClient.FileChooserParams fileChooserParams){
if(mUMA != null){
mUMA.onReceiveValue(null);
}
mUMA = filePathCallback;
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if(takePictureIntent.resolveActivity(MainActivity.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);
contentSelectionIntent.addCategory(Intent.CATEGORY_OPENABLE);
contentSelectionIntent.setType("image/*");
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;
}
Create image file function, as mentioned in the above code we need this to create new temp file to upload.
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);
}
