Hello everyone.
I'm having a problem with an Android app. The app use a webview control to display and navigate a webpage. On the webpage I have a radasyncupload for uploading images. This woks perfectly both on the web page and the app FOR LOLLIPOP(Android 5.1.1).
My problem happens when I try to upload an image on Jellybean (Android 4.1.2), I'm able to upload the file to the control but when I hit the "Upload" button, that process the images I get the error "Parameter no valid" in the WEBPAGE code line "Bitmap upBmp = (Bitmap)Bitmap.FromStream(CurrentFile.InputStream);"
On the android app, when I hit the file upload bar it calls the following code:
public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType, String capture) {
//openFileChooser(uploadMsg, acceptType);
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 );
}
And after I choose the file:
public void onActivityResult (int requestCode, int resultCode, Intent data) {
// code for all versions except of Lollipop
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
if(requestCode==FILECHOOSER_RESULTCODE) {
if (null == this.mUploadMessage) {
return;
}
Uri result=null;
try{
if (resultCode != RESULT_OK) {
result = null;
} else {
// retrieve from the private variable if the intent is null
result = data == null ? mCapturedImageURI : data.getData();
}
}
catch(Exception e) {
Toast.makeText(getApplicationContext(), "activity :"+e, Toast.LENGTH_LONG).show();
}
mUploadMessage.onReceiveValue(result);
mUploadMessage = null;
}
} // end of code for all versions except of Lollipop
...
It's a very strange problem and every help will be very appreciated.
