I have three activities in my android app. First activity is main application screen which gives option to open second screen containing second activity. But when I click on the button on second activity which was supposed to open third activity screen.
I get "Application has stopped unexpectedly" error.

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...........
I still have a problem to develop a convenient app to the user. because i am struggling using the activities, intent and intent filters. www.developer.android.com/reference not fit for me to understand these things. can you suggest me a fine example code or tutorial to understand how these things are getting worked.

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?
View 2 Replies View RelatedIs 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:

In the first example this line executes without errors so I'm wondering what could be wrong here.

How can I differentiate an android Activity from a SubActivity programatically?
Is there any api for that?
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.

View 7 Replies View RelatedI`m trying to develop an application, just to test the ability of android to call an activity with an intent based not in the specific class name but specifying the action, category and data information. Acording to this link
http://developer.android.com/guide/topics/intents/intents-filters.html
only three aspects are consulted when comparing an intent object to select the future activity to run. I created two android projects (and two activities), the first is the main project who sends the request and the second can be called directly or through the filter. This is the call of the activity in the main project:
CODE:..................
This is the part of the manifest that specifies (or at least I try to specify) in the secondary activity that it`s available to be selected to run with that information:
CODE:...............
I installed both separatelly and I was expecteing to see the second activity after the called but instead I got an ActivityNotFoundException. By the way if I comment the t3.addCategory (Intent.CATEGORY_HOME); line and change the t3.setAction (Intent.ACTION_EDIT); to t3.setAction(Intent.ACTION_VIEW); the browser is executed so I think the problem is in the manifest of the second activity.

View 4 Replies View RelatedSo I'm working on a service that will handle requests to send data to a socket.I've done socket programming in a service before, but only within the same application. I'd like this to just sit and do nothing until any application wants to give it data to send. That's all well and good.I have register an intent filter and the usual stuff and can process the data. But I want to process the data coming from different activities in different threads (subsequent calls from the same application will be computed on the same thread).Is there a way to get the calling package or app or whatever? I'd prefer not to require passing in an identifier as an extra to prevent spoofing. (It's not a serious security concern, it's just each application needs its data processed in the order that it's received.)

View 2 Replies View RelatedI have T-Mobile, with the old Hotspot@Home billing feature that gives me unlimited UMA minutes (used to have two blackberries and used UMA a lot). I have really missed this with my Nexus One. With TMO rolling out Kineto's application for "WiFi Calling" I am trying to figure out what is possible for my Nexus One, currently at Android 2.2.1 (FRG85).Is the Kineto deal only going to be for TMO builds of Android? I have read that Kineto's business model is to not sell direct, hence no availability in the Market. Since my Nexus One gets its Android system updates independently, this would mean I can never get an update with Kineto built-in, right? If I were able to install Kineto, would it look like UMA to TMO so the calls would be covered under my unlimited H@H plan? Any bright ideas on how I can get WiFi Calling (the TMO supported plan that uses my TMO number, not some SIP implementation or Google Voice)? I prefer not to root, but if I have to root to get UMA, I will.

View 2 Replies View RelatedI have been developing a game on Android and wrote a wrapper for J2ME classes,
When notifyDestroyed() is called in my ME program and calling finish() but the application doesn't close correctly.
The App goes to background and when launched again it shows an error message and presents an option to "force close" the App, if i force close it and launch again, the app launches fine but again the same has to be repeated upon every launch..
Can you please explain why the App is not being erased from memory when finish() is called.
when i check the log i found no exceptions when closing but when launched again it throws a null pointer exception.
for now to work around I placed "System.exit(0)" after calling finish () so that the app is exited abruptly, but am waiting for a valid answer on whats going on behind...?
I've been using code like: activity.finish(); activity.startActivity(new Intent(activity, activity.getClass()));
in two places: onResume(), and in an onClick() method of an AlertDialog. I'm getting the desired results when the code is called from onClick(), but I get mysterious null pointer exceptions while the runtime is trying to execute my onPause(). Is calling finish() from within one of the Activity lifecycle callbacks always a bad idea?
This code makes me nervous even though it works in the onClick(). After I call activity.finish(), I would think activity is in a questionable state by the time activity.startActivity() is invoked. Seems like an invitation to race conditions.
My use case is setting UI preferences (e.g. a different layout) in a PreferenceActivity. When I return to the main activity's onResume(), I check for preference changes and if a new layout is requested, I use the code snippet above.
