问题 Firstly there are 2 different asynch classes called AsyncMySqlInsert and CallSoap and I am using CallSoap in AsyncMySqlInsert. Secondly each one of them has progressdialog. They can display their progressdialogs without exception if they run separate from each other. But if they run together an exception called java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare() occurs. So how can I manage progress dialogs in separate threads? class

问题 Perhapse I am lucky on the fatal error on different signals.

问题 I know that there are lot of questions about this but I couldn't figure out the solution from those questions. I am getting null in a token from GCM. many people have done this using class, but I am doing this in background thread in same class. It returns null in regId. OnCreate if (checkPlayServices()) { gcm = GoogleCloudMessaging.getInstance(this); regid = getRegistrationId(context); if (regid.isEmpty()) { Log.e(TAG, "registering in background"); registerInBackground(); } else { Log.e(TAG,

问题 This question already has answers here : AsyncTask, must it take such a performance penalty hit…? (4 answers) Closed 6 years ago . I'm having a strange behaviour in my code: parsing a local xml file on simulator with asyncTask takes longer than parsing it on main thread. Here is my code with AsyncTask: public class MostraTutti extends SherlockActivity { ListView lv; final List<ListViewItem> items = new ArrayList<MostraTutti.ListViewItem>(); final ArrayList<String> nome = new ArrayList<String>

问题 I want to transfer data from Android device to the java desktop server. I have a text and button. As I press the button on the device, the text should be displayed on the java desktop server. I also have added AsyncTask in the client. The error code has also been added. The port i have used is 4444 and the ip address I used is of my local host address. I am doing a very silly mistake. Can you please guide me. I run the server code, it first gives me : Server started. Listening to the port

问题 I have this peace of code, that fetches some xml data from an url. It does it's job properly but the problem is that while it downloads and parses xml the UI freezes, and that might be a problem for the users. Here is the class @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.kategoria); // getting intent data Intent in = getIntent(); String cat_name = in.getStringExtra("kategoria"); //Update Textview TextView kategoriatw

问题 EDIT: SOLVED. Sorry guys, it occurred to me that while my loading of my data was occurring in a background thread, the callback that parsed the data was not. The parsing of the data took a very long time, and that was what was locking my thread. EDIT: It has come to my attention that my overarching problem (the ProgressDialog no longer spinning) may be caused by a problem with my use of a ProgressDialog rather than the UI thread being blocked. If that is the case, how do I fix that? EDIT: to

问题 While I'm updating my database I want to display a progress dialog. My problem is that the ProgressDialog is getting late to appear,after 4-5 seconds, then appears and disappears very fast, it stays on screen few milliseconds almost you can't see it, then new data are shown in the list immediately. This makes me think that the ProgressDialog is waiting for database to be updated(it doesn't take much, about 4,5 seconds) and then it shows on the screen but is dismissing very fast. I would like
