Im writing a program that offers a quick reply dialog upon receipt of an SMS.
However, I am getting an unexpected result. When I receieve an SMS, the appropriate dialog activity comes up displaying the correct phone number and message, however there is a second activity behind it that is the 'default' activity in my program (it is what opens when i launch my application)
I do not want this second activity to come up. The quick reply activity should come up by itself over top of whatever the user was doing before.
The 'floating' activity:

I'm writing an application that starts with a loading activity. In the loading activity the app requests html from web and parses the html, then it sends the parsing result to the main activity. The main activity has several tabs, and contents of these tabs are based on the result of parsing.For example, the result of parsing is a list of strings ["apple", "banana", "orange"], and I need to pass this list to main activity, so that the main activity can create three tabs named after three fruits.I would like to know if there is any way to pass a list of strings among activities, BTW, is it the common way of do this?

This is the method from main activity. When onPause() is executed isRunningInBackground is set true.
When I tried to debug it when the main application was running in the background the line
startActivity(intent) had no effect (the activity didn't appear).
Does anyone know how to midify the logic in order to start an activity from the main activity when the main activity is running in the background (after onPause() is called)?
Need an example of how to create/start a new activity from the main activity. I have a button click event on the main layout. Originally I just used setContentView(R.layout.secondactivity); which brings up the layout but I don't think that is correct since the secondactivity class is not instantiated at this point yet. I have looked for such an example and can not find one.
View 3 Replies View RelatedI hav an app that is like a relational database. There is a main app activity that users manage things with. There is also a widget that will display important info and add data to the database. When the widget is clicked, a configure class displays a way for the user to edit data. When the configure activity is done, the widget is updated and instead of going back to the home screen, the apps main activity is started. I can't find where the main activity is being called from. Wouldn't I have to create an intent and start Activity() to get this behavior? When done updating, I want the home screen and not my app.

I'm working on an app that launches the browser activity to perform a Twitter OAuth authorization. This process uses a callback url which will re-launch the activity that started the browser activity in the first place.My problem is that the browser pages remain in the history stack and when the user then clicks back from the preferences activity that launched the browser in the first place, they don't go back to the app's main activity, but instead are brought back to the browser. I've tried adding flags to the launching intent to prevent history and reset on clear, but it doesn't seem to work when running on my phone, only on the emulators.
View 1 Replies View RelatedFrom digging around a bit, getAssets() is an inherited method from ContextWrapper. It returns an AssetManager, and using open() it can return an InputStream. What I'm attempting to do at this point, is use the GLSurfuceViewActivity, Cube and CubeRenderer to work and learn off of and read in vertex data from a binary file. I've already created the binary output by parsing a model obj file and added to the assets directory. My Shape class (modified from the Cube class) does not have access to calling getAssets() since it's not a subclass of Activity or ContextWrapper. Once I accepted that, I tried to think of the best way to read in the data (without storing it extra places) to the Shape class. What I did, and seems to be working okay, was modify the Shape and ShapeRenderer constructors to accept an AssetManger as a parameter.
View 3 Replies View RelatedIs there a way to manage application activities by hand, like this: user activating an application from menu, it does some initialization, then creates some activity (is it necessar y to declare all activities in the application manifest?), and listens to it's events. On some event application decides to close one activity and open another - so it contains all the application logic. Didn't found anything like this in examples, they all have all the logic in the activity classes. Maybe I need to user Services? (Maybe I don't understand right, what an activity represents. For me it's like window in windows, or Displayable in j2me) I'm very new to android development, trying to understand the basics.

View 5 Replies View Relatedso the application I've written has a service (that tracks GPS data) with a single main activity that binds to it with bindService in it's onStart() method, and unbinds from the service in it's onStop() method using unbindService( ServiceConnection ). I also have an activity which is an options screen, that is launched by pressing a button on the main activity. On this options screen, I have a checkbox that says "Run in background", which, if set to true, means that when the user exits the application with eier the Home or Back buttons, the service will continue running, not turning the GPS off. I do this by calling this.startForeground onUnbind, and this.stopForeground onRebind, if the setting is set to true, and stopping and starting my location reader onUnbind and onRebind respectively if the setting is false. If the service is running in the background, it also displays a notification to ensure the user understands that the GPS is still running and draining their power. This notification is displayed and stopped by relying on the startForeground and stopForeground methods......

View 5 Replies View RelatedAre there any scenarios on Android where a process can be instantiated (classes loaded, etc.) and a non-main activity launched without going through the main activity? Background: my app has a single main activity (android:name="android.intent.action.MAIN" and android:name="android.intent.category.LAUNCHER"), some secondary activities, and a preferences class providing static methods meant to be called from anywhere. These static methods' implementations require a Context, and so the class has a static Context member s_context; the static methods assert that s_context is non-null before using it. The very first thing I do in my main activity's onCreate() method is pass getApplicationContext() into the preferences class so it can set s_context.

I need to be able to be able to call readAsset from outside of the main activity of my application. I have heard people mention needing to pass the Context around, but the language has been very vague. Can someone describe the steps necessary to add the ability to call readAsset to an existing class that is not the main activity? Creating a public function in the main activity and having others call that will not work as the place I need to add readAsset to, is in a separate thread.
View 1 Replies View RelatedI have activities A and B. The A is the one with LAUNCHER intent-filter (i.e. the activity that is started when we click the app icon on home screen). A launches B using start Activity(new Intent(A.this, B.class)). When the user has the B activity open, and then put my application into the background, and later my application's process is killed, when the user starts my application again, B is opened instead of A. This caused a force close in my app, because A is the activity that initializes the resources my app needs, and when B tried to access the uninitialized resources, B crashes.

This is my new Activity for a WebView. When the user clicks back, I simply want to close this Activity and return to my previous one. Notice, I put "onKeyDown" -> Finish. However, it's not working. Instead, I click "back", a blank white screen comes up.. (it doesn't even hit that onKeyDown Statement when I try to debug it)! When I hit "back" the second time, then it will go back to my previous Activity.
Im wanting to stop all threads when my main activity closes as some are still running afterwards and are giving NullPointerException as they try to access Array Lists which no longer exist. however none of the obvious methods are working and they are also deprecated. is it possible as im currently using a try/catch statement as a workaround but would prefer a fix.
View 1 Replies View RelatedI think I've missed something in how Android is supposed to work! I have the main Activity with a menu option that opens the preferences screen. What I need is a way for any changes that were made to be communicated back to the main Activity as soon as the preference is activated. At the moment the only way I could get it working is by using the intent data that gets sent back when the prefs activity closes but this isn't really enough. The reason why it needs to be instantaneous is that one of the preferences is a 'Clear cache' button, so I would like the data to be deleted when the user requests it and no later!
