Android :: Send String / Int From SubActivity To MainActivity Without Close SubActivity
May 5, 2010
does anyone know how to get result from subactivity to MainActivity without close the subactivity? i know the usual way is using method called "startActivityForResult (Intent intent, int requestCode)" and inside the subActivity set the result 1st before finish(); method
setResult(requestCode,intent); finish(); then the function called "protected void onActivityResult(int requestCode, int resultCode, Intent data)" which is inside main activity will get the result. BUT... by using that way, it will close my sub activity and the system will go back to main activity...........

My application supports twitter and needs to open browser for OAuth. When the user clicks the Share on Twitter button, the main activity will create another subactivity (TwitterActivity) to handle twitter authentication issues. Here is a flow graph showing how activities are invoked currently. Main is short for MainActivity and Twit for Twitter Activity. startActivity() OAuth intent OAuth callback finish()Main ---------------> Twit ------------> Browser --------------> Twit --------> Browser As you may notice, after the TwitterActivity calls finish() to stop, it will now return back to MainActivity, but Browser instead. How can I make it return back to MainActivity?

Is there any way to send String messages from the parent Activity (running on B/g) to the subActivity (currently running)?
SubActivity is invoked using intent and startActivity(intent);
I want to open EditBox(sub activity) using this method and then update this editBox according to the process going on in the parent activity () and later want to finish() this Box when process in the parent activity completed.

I created an application which consists of several activities. If I start a subactivity named DlgTitleTags from main activity everything goes well.
Another case is when I start a subactivity DlgLibrary and then from DlgLibrary DlgTitleTags the execution fails on line:
CODE:..................
In the first example this line executes without errors so I'm wondering what could be wrong here.
This is the copy from log:

I am developing a simple app which does a little bit of image-processing. It's divided in two activities; the main one with some display elements and the second one which is used to capture images off the phone's camera.
To discribe my problem: I start the app, capture an image (by starting a new Intent with the subactivity) and all data is displayed correctly. If I capture another image after this, I run in an java.lang.OutOfMemoryError - bitmap size exceeds VM budget
I dont store the captured bitmap, in the second activity I just extract some data from it and pass it to the main-activity; finishing (finish()) the sub-activity afterwards.

Usually, I putExtra inside an Intent to transfer stuff between Activities. But it seems like I can't do this with a Service? Bundle extras = getIntent().getExtras(); That doesn't work for a android Service. How do I send a string from an Activity to a Service then?

How to fix the MMS issue with MIUI V5 on the HTC One XL(AT&T version). I noticed that the One S has a fix, however I can't figure out what they are saying about replacing the framework files and what not. If your not familiar with the issue, trying to send/receive MMS causes the messaging app to force close.

Are there any tools that go through the file taken from the xcode project and build the xml needed to use the strings in android? This tool should be easy to build but I appreciate any pointers to already working tools.

In Android, capturing date from datepicker and storing as string in sqlite. Sorting by date doesn't work because they're strings (unless I'm doing it wrong.I've googled this issue for ~5 days, and it looks like there should be a way to capture the date from the date picker, convert it to a Long, store it in sqlite as a Long, select and sort on the Long date value, then convert the Long back to a "mm/dd/yyyy" string for display. I've tried various combinations of parse statements, Date, FormatDate, etc. with no luck at all.On activity start, get today's date and display it in button which calls the datepicker.Capture new date from datepicker (if one is entered), save it as a long to sqlite.On opening an activity showing a listview of records, select from sqlite with orderby on date (Long), convert Long to "mm/dd/yyyy" string for display in ListView.

I have preferences where you can enable/disable what items will show up on the menu. There are 17 items. I made a string array in values/arrays.xml with titles for each of these 17 items.
I have preferences.xml which has the layout for my preferences file, and I would like to reference a single item from the string array to use as the title.
In the Android developer reference, I see how I can reference a single string with XML, but now how I can reference a string from an array resource in XML.

I have a class that creates a view to gather data via a function getView() that provides a view with an EditText.This class has also has variable answer.When the user chances the EditText I want to store the content of the EditText in answer.If I would use an onKeyListener I fear that the answer will probably get stored before the last letter is entered.Is there a good way to handle this in the getView() function via some other listener?

I have an Android app where I want to check to see if an app name that is installed matches a string passed to the function containing this code.Assuming you called checkInstalledApp('SetCPU'); and the app name on the phone is called the same thing it should return true. However, it never does. I logged the results and it should match up but it does not. Can anyone please enlighten me as to why this doesn't work?

Does anyone have any idea how to find the n-th field (string) in a delimited string where the delimiters (separator) could be either a single char or several chars.and the syntax for user-defined function is FindNthField(string,separator,position)so position 3 would return three,The separator in use would actually be Chr(13).This has to run on Android and so should be efficient.

I just want to read <string-array> resource elements into a String array. I don't want to make a view or anything and mess with adapters - just want to transfer the elements. Is there a built in class for this? Or do I need to treat the resource file as a regular file?
