show() progressdialog in asynctask inside fragment
- by just_user
I'm trying to display a progressDialog while getting an image from a url to a imageview.
When trying to show the progressDialog the parent activity has leaked window...
Strange thing is that I have two fragments in the this activity, in the first fragment this exact same way of calling the progressdialog works but when the fragment is replaced and i try to make it again it crashes.
This is the asynctask I'm using inside the second fragment with the crash:
class SkinPreviewImage extends AsyncTask<Void, Void, Void> {
private ProgressDialog progressDialog;
@Override
protected void onPreExecute() {
progressDialog = new ProgressDialog(getActivity());
progressDialog.setMessage("Loading preview...");
if(progressDialog != null) progressDialog.show();
progressDialog.setOnCancelListener(new OnCancelListener() {
public void onCancel(DialogInterface arg0) {
SkinPreviewImage.this.cancel(true);
}
});
}
@Override
protected Void doInBackground(Void... params) {
try {
URL newurl = new URL(url);
Bitmap mIcon_val = BitmapFactory.decodeStream(newurl.openConnection().getInputStream());
skinPreview.setImageBitmap(mIcon_val);
} catch (IOException e) {
Log.e("SkinStoreDetail", e.getMessage());
}
return null;
}
@Override
protected void onPostExecute(Void v) {
if(progressDialog != null) progressDialog.dismiss();
}
}
I've seen a few similar questions but the one closest to solve my problem used a groupactivity for the parent which I'm not using.
Any suggestions?
