this is Async Task
这是异步任务
public void Gtalk_logInComplete(String Uname, XMPPConnection _connection) {
Log.i(TAG, "Uname" +Uname);
Uname = current_username;
_connection = current_connection;
ForwardAction task = new ForwardAction(); // this is line no 579
task.execute();
}
private class ForwardAction extends AsyncTask<Void, Void, Void> {
private ArrayList<String> contactJids;
private GmailXmppClient Gtalk_xmpp_client;
private ArrayList<String> contactNames;
@Override
protected void onPreExecute() {
super.onPreExecute();
show();
}
protected Void doInBackground(Void... params) {
// new Thread() {
// public void run() {
synchronized (this.contactJids) {
Roster roster = this.Gtalk_xmpp_client.getRoster();
String file_name;
for (RosterEntry entry : roster.getEntries()) {
if (entry.getType() == ItemType.to || entry.getType() == ItemType.both) {
this.contactJids.add(entry.getUser());
this.contactNames.add(entry.getName());
contact_db.open();
boolean yes = contact_db.checkUsername(entry.getUser());
Log.i(TAG, "Con=" + yes);
if (!yes) {
Bitmap buddy_img = buddyImage(entry, current_connection);
if (buddy_img != null)
file_name = Store(buddy_img);
else
file_name = "";
if (entry.getName() == null)
contact_db.createContact(entry.getUser(), entry.getUser(), current_username, file_name, "GOOGLE");
else
contact_db.createContact(entry.getName(), entry.getUser(), current_username, file_name, "GOOGLE");

contact_db.close();
return null;

protected void onPostExecute(Void aVoid) {
super.onPostExecute(aVoid);
hide();
}
}

This error happens when you try to update a view from a thread which you can't do. You'll either need to update your view from onPostExecuteor use runOnUiThreadto update your view.
当您尝试从无法执行的线程更新视图时，会发生此错误。您要么需要更新视图，onPostExecute要么使用runOnUiThread来更新视图。
You can use runOnUiThread as follows:
您可以按如下方式使用 runOnUiThread：
runOnUiThread(new Runnable() {
public void run() {
// your code to update the UI thread here
}
});
