Why do I get in an AsyncTask which should a android.os.NetworkOnMainThreadException? I thought that an AsyncTask is the solution to that problem. The exxeption is on line 7.
private class ImageDownloadTask extends AsyncTask<String, Integer, byte[]> {
@Override
protected byte[] doInBackground(String... params) {
try {
URL url = new URL(params[0]);
URLConnection connection = url.openConnection();
InputStream inputStream = connection.getInputStream();
ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream();
int bufferSize = 1024;
byte[] buffer = new byte[bufferSize];
int len;
while ((len = inputStream.read(buffer)) != -1) {
byteBuffer.write(buffer, 0, len);
}
return byteBuffer.toByteArray();
} catch (IOException ex) {
return new byte[0];
}
}
}
I want to use it for downloading a picture.
public byte[] getProfilePicture(Context context, String id) {
String url = context.getString(R.string.facebook_picture_url_large, id);
ImageDownloadTask task = new ImageDownloadTask();
return task.doInBackground(url);
}
