Android :: Pass multiple parameters to AsyncTask


Android :: How To Pass Parameters To AsyncTask's OnPreExecute()

Jun 19, 2010

I use an AsyncTask for loading operations that I implemented as an inner class. In onPreExecute() I show a loading dialog which I then hide again in onPostExecute(). But for some of the loading operations I know in advance that they will finish very quickly so I don't want to display the loading dialog. I wanted to indicate this by a boolean parameter that I could pass to onPreExecute() but apparently for some reason onPreExecute() doesn't take any parameters.

The obvious workaround would probably be to create a member field in my AsyncTask or in the outer class which I would have to set before every loading operation but that does not seem very elegant.

Android :: Can Pass Different Types Of Parameters To An AsyncTask

Oct 13, 2010

I want to implement a generic, thread save class which takes the RessourceId of an ImageView and the Url (http) where the desired image file is stored. It'll download the image and fills the src of the ImageView in the UiThread.

I thought AsyncTask would be the best thing for me. However I noticed that I only can pass one type of parameters to the doInBackground() Method. Like an Array of Urls. Is that true? What would u suggest me?

Android :: Pass ArrayList Parameters Between Two Activities

Apr 19, 2010

Today I met a problem, I need to pass a ArrayList<MyClass> from an activity to another. I dont know what the Intent exactly do when I use putExtra to pass in an ArrayList<MyClass> object. I guess MyClass need to implement Parcelable interface, so I just did it. But still, it does not work. Maybe I need to create a Bundle and then use Bundle's putParcelableArrayList method to put my ArrayList<MyClass> object in, and then pass this bundle as parameter of putExtra to the intent. So crazy! I am lazy, I just want to pass an ArrayList<MyClass> object simply, is there a simple way??

Android :: Pass Parameters To The Marketplace Installer For An App?

Feb 10, 2010

When providing a user on a mobile, a link to an android application via a web page, it is possible for params from the url to be passed to the app being installed.

I'm guessing the answer is no - but it doesn't help to ask.

The reasoning being that it would be handy for some situations to have a generic app that pulls config information from the referrer.

Android : Pass ActivityContext To AsyncTask In Order To Manipulate Views?

Oct 13, 2010

This function runs on the UiThread, but it seems that doesnt mean it also has access to the activity context. Shall I implement to my AsyncTask a public Setter to pass the activity (as reference)?

protected void onPostExecute( Bitmap bitmap ) {
//following is underlined red due to missing context
(ImageView)findViewById(ResId)).setImageBitmap(bitmap);}

Android :: Contact Search With Multiple Parameters

Aug 4, 2010

I am trying to do a Contacts search on Android using Contacts Contract. I would like to search on multiple parameters, e.g. - Where name = myname AND email = myemail AND nickname = mynickname, etc. I have it working w/ just name, but need the syntax to add email and nickname as search params. I know they are stored separately from display name & have a different format. The code below is what is working for the search by just name. How can I add to the selection variable to also search by email and nickname? CODE: String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '" + ("1") + "'"; selection += "AND " + ContactsContract.Contacts.DISPLAY_NAME + "= '" + cp.name + "'"; Uri uri = ContactsContract. Contacts.CONTENT_URI; String sortOrder = contactsContract. Contacts. DISPLAY_NAME + " COLLATE LOCALIZED ASC"; Cursor myCursor = mApp.managedQuery(uri, null, selection, null, sortOrder);

Android :: Instance Variable Of Activity Not Being Set OnPostExecute Of AsyncTask - Return Data From AsyncTask

Jul 28, 2010

I'm trying to figure out the correct way to create an AsyncTask to retrieve some data from the internet and then to take that data and bundle it up in an Intent and pass it to a new activity(A list display). So in the first activity I just have an EditText and Button. In the event of an OnClick the task should be called and when it is finished the data should be bundled inside an Intent and passed to the next Activity. The problem is when I take the results from onPostExecute and set them to an instance variable of the main activity, that instance variable is still null when the task is complete. Here is the barebones version of the code:

CODE:...........

When I debug the application I see onPostExecute does contain a valid PlacesList full of results, so why is the instance variable places set to null after the task is executed? I am going about "returning data" from an AsyncTask incorrectly?

Android :: Passing Parameters To New Activity

Mar 2, 2009

I'm programming an Activity that launches a second one through startActivity just like in the Forwarding example. The main difference is that I'd like to pass some data to the second Activity when starting it, for example an item selected in a list owned by the first Activity. I can't find how to do that. Am I missing something? I guess I do.

Android :: Search Market By Using Various Parameters

Feb 18, 2010

This link describes how to search the Android Market for apps using various parameters:
http://developer.android.com/guide/publishing/publishing.html
I'm having a heck of a time figuring out how to format a link for my apps published by my company using this format. For searching by developer name, the doc says to use the following format:
market://search?q=pub:<Developer Name>

It also says it returns exact matches only. My publisher name is "Polyclef Software". I guess I'm wondering why Google can't make a market search feature that searches for substrings in the publisher's name, but aside from that, how am I supposed to format the link? Neither of the following work:
market://search?q=pub:Polyclef Software market://search?q=pub:Polyclef+Software
I've tried a number of variations now and nothing works.

Android :: Add Parameters To A HTTP GET Request?

Jun 2, 2010

I have a HTTP GET request that I am attempting to send. I tried adding the parameters to this request by first creating a BasicHttpParams object and adding the parameters to that object, then calling setParams( basicHttpParms ) on my HttpGet object. This method fails. But if I manually add my parameters to my URL (i.e. append '?param1=value1¶m2=value2') it succeeds.

Android :: Camera.Parameters.getFlashMode­()

Jan 19, 2010

I am developing an app that uses the phone camera, and I want to set the Flash Mode, if flash exists. From documentation, it looks like I need to call Camera.Parameters.getFlashMode() and check if it returns null to determine if flash exists. Note: getFlashMode() is supported from API level 5

However, when I try to run this app on a phone with cupcake, I get an error: 01-19 14:02:43.404: ERROR/dalvikvm(18891): Could not find method android.hardware.Camera$Parameters.getFlashMode, referenced from method ...

I tried to call this code based on SDK version as follows, but that does not work either. Looks like there is a class verification thats fails at init:

CODE:............................

So now I am wondering if there is any other way to check if flash exists? or is there a way to conditionally compile code based on mSdkVersion?

Android :: Launching Google Maps With More Parameters

Aug 20, 2010

I have read a lot of stuff about launching Google Maps in Android. That's pretty easy:
Uri uri = Uri.parse("geo:38.899533,-77.036476");
Intent it = new Intent(Intent.ACTION_VIEW, uri);
startActivity(it);

The problem is that the map is shown at a high zoom level and there is no marker on the map. So, if the user move a little bit or something happen, the point is lost. Is that possible to add a marker like this:

http://img.skitch.com/20100820-da3n4r7h5xbsu6bsx4p4ujjghc.jpg
or like this:
http://img.skitch.com/20100820-qg7k2m5wtwm3j5phphrgc8tb53.jpg

So I can be sure that even if the user move the map, he will be able to find this place again.

Android :: Set Flash Mode Camera.parameters

Oct 7, 2010

I'm trying to use the camera in an Android app using the 1.5 API. I want the camera to flash for every picture. However, when I looked at the API for camera.parameters, the setFlashMode() method is only supported for 2.0 and higher. Yet my Cliq XT, which runs 1.5, has a flash that I can set in the menu - I take this to mean there is a way to do this for the 1.5 API, though I was unable to find it.Does anyone know how to set the flash mode using the 1.5 API?

ImageView i = new ImageView(this);
i.setImageResource(R.drawable.blue_1);

mRelativeLayout.addView(i);
setContentView(mRelativeLayout);

Android :: Open A New Screen With Additional Parameters?

I've read through the FAQ of Android Dev Guid (http://developer.android.com/guide/appendix/faq/commontasks.html#opennewscreen) but I'm not sure how can I open a new screen with additional parameters passed into it.

Let's say I'm going to open screen2, with a variable indicating the current user name so that I could greet the users. Is it possible?

Intent i;
i = new Intent(this, screen2.class);
//How to pass variable to screen2?
startActivity(i);
