Android :: General Activity Order - Linear Implementation
Jul 17, 2010
First I have my app running currently and its working fine, I just question how I implemented it. I come from a linear C++ background and this Activity/Intent thing is a little new to me. Here is how my app works currently (order of activities started)
("->" = Starts Activity, "<-" = Returns from activity)
MainActivity -> Login Activity <- onActivityResult function displayListOfItems ...
I am wondering if I should switch the starting intent as follows:
LoginActivity MainActivity function displayListOfItems
The issue I had with the second scenario was that pressing the back hard key would take me from the MainActivity back to the LoginActivity and I didn't like this. I guess to sum up my question, is it normal for the MainActivity to handle all subsequent starting of activities or is it common to do a more linear implementation?

For a rather crazy reason I am trying to pass a linear Layout from one activity to another. Should I use an intent extra for this? What would be the right way to create a Linear Layout in one activity and then spawn a new activity using that linear Layout.

I'm developing an app that starts with a main menu, and then continues through three different steps (activities) to a final activity where the task is marked complete. On this last activity, i have several additional options (add note, share, etc..) and i also have a return to main menu button.
My question is.. how do i stack the activities so that calling finish() on the final activity will return back to the first activity launched? i am currently just starting the new activity via an intent, so pressing back on this screen doesn't return me to home as i would like.

I wanted to implement the application specific VPN client in android, that is vpn connection once established should be only available to our application and rest of the apps in android device should make use of normal internet connection.
To elaborate my need more, i have an application already which connects to corporate email, files and other data from internet normally but for some security reason we need it to be go through tunnel within our application and access everything within via tunnel basically want we are looking here is security while accessing company corporate network.
Since we are new to something like this we don't have a hint on how to start what protocols to use etc (we are assuming ipsec l2tp for now).
And between we are just looking to send and receive data over tunnel, there is nothing more or need to control computer on the network all we need is to route data through corporate firewall and should support multiple vpn servers such as cisco, microsoft etc. How complex or how feasible to implement it.

I have run mediaplayer in SDK which can play media in res/raw folder successfully on emulator , but now I wanted to run it on my hardware which have already successfully implemented the android kernal and file system and audio, video drivers etc. I have no experience to implement JAVA app . I once implemented mplayer app written in C to my linux OS which only need to copy the final executable file , but now I don't know which files or folder should I copy to my platform because I have no basic knowledge of Java although I have run successfully on my emulator.

I've been playing around with the new LVL announced yesterday and wanted to write a policy which only stops the user when it is certain that he does not have a license. In other words, the policy will only "dontAllow" the user if the last meaningful response from the licensing service was NOT_LICENSED. Therefore, if the user is offline when they first use the app, then they will be allowed in. The idea behind this is that I don't want genuine paying users to ever (within reason) be inconvenienced by this licensing system. The downside is that all the user needs to do is clear the app data and go offline before restarting the app. The app will continue working until they go online (and restart the app). My thoughts are: 1. Most users won't know about that workaround 2. Those users that are happy to use that workaround, probably wouldn't pay for the app anyway.

We have discovered a potential bug in the implementation of AppWidgets. Here is a simple reproducer.
Attached is the code for an application containing a TestActivity and a TestWidget. TestActivity extends MapActivity and TestWidget is a simple widget provider which updates a TextView every 2 seconds. Now if the TestActivity is launched with no instance of TestWidget running, it works just fine. But if the TestActivity is launched after placing the TestWidget on the home, it results in ClassNotFoundException. Here is what we get:
CODE:.............
So it seems we have an inconsistency in the way the class loader works for the same apk.
WORKS - Launch the application by itself, without invoking the Widget. DOES NOT WORK - Create a Widget on the Home screen and then launch the application from the launcher.
The source code for this application (http://www.yousendit.com/ download/TzY3ZGVhZy96NE4zZUE9PQ) has been attached. Hope someone from the Android team can shed light on this behavior.
This error is seen on the 1.5r3 SDK. Not sure if this has been addressed in 1.6 and 2.0 SDKs..

I'm working on an LVL implementation and I want to use as many different device identifiers as I can. I have considered using IMEI numbers but I've discarded that because a) it's intrusive and b) not all devices will have them.
What might I use to fingerprint a phone for license verification?
As an aside, how have your experiences with LVL been so far? Any pitfalls? I'm not asking for anyone to share their implementation details as that would give the hackers ideas.

I would like to implement the similar widget as QuickContactBadge from which I can launch some internal activities. I checked out the source code for QuickContactBadge, QuickContactActivity etc and simplified them to accommodate our requests. It can launch and display at correct position. However, I can not see the original view below the quick contact tack no matter how I try. And I found the window created by QuickContactWindow is quite small and I tried to set the background etc. Nothing works. Who can help or give some guidance about how window works? Say, from Activity A, I click on image, I launch a new activity (or window), how can I make the Window of Activity A is still visible? Or more general, what is the best way to achieve similar behavior like QuickContactBadge?

In iPhone there is Cocoa Asynchronous socket library. Is there a similar library in Java for Android? Can it be done using Java Asynchronous sockets(NIO library) or is there a way I can make use of NDK for Android and use native libraries for asynchronous sockets?

Has anyone tried to write his own implementation of ViewGroup with some TextViews in it? I have a problem, that TextViews in such an implementation don't respect gravity attribute (TextView.setGravity(Gravity.CENTER);) and text is positioned in the top left corner.
If enyone is interested, I just overwrote method onMeasure() (for all my TextViews) and changed call from super.onMeasure() to setMeasuredDimension(int, int) and gravity started to work normally.
Basically, in my custom layout I use the following class to display text:

I'm implementing a service that contains a thread to handle all time consuming operation. My core service logic is in a different thread than the ui or main thread. According to the Android document, when the OS plans to free some system resource, it will call onDestroy () on the service and only when onDestroy() returns it will kill the process hosting the service, thus giving opportunity to the service to cleanup.Now, when onDestroy() is called, I want to send a message to my service thread to do the necessary cleanup. Only when the service thread acknowledges that the cleanup or shutdown is complete, onDestroy () should return. I could find a way to send asynchronous messages to threads and the corresponding processing of the messages, but not able to figure out how I need to implement onDestroy(), such that it would send a message to the service thread and should wait for a result, before returning.

I'm trying to make (for learning purposes) my own implementation of a simple AdapterView where items comes from an basic Adapter (ImageAdapter from sdk samples).
Actual code is like this:
public class MyAdapterView extends AdapterView<ImageAdapter> implements AdapterView.OnItemClickListener{
private ImageAdapter mAdapter;
public MyAdapterView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
initThings();}
private void initThings(){
setOnItemClickListener(this);}
@Overridepublic ImageAdapter getAdapter() {
// TODO Auto-generated method stubreturn mAdapter;}
@Overridepublic void setAdapter(ImageAdapter adapter) {
// TODO Auto-generated method stub
mAdapter=adapter;
requestLayout();}
View obtainView(int position) {
View child = mAdapter.getView(position, null, this);
return child;} code...
This isn't a coding masterpiece, it just displays a pseudo-listview with pictures. I know i could've used ListView, GridView, Spinner, etc. but i'm relative new to android and i'm trying to figure out some things on it. Well, the question here is Why is my onItemClick not firing?
Using the same ImageAdapter with a GridView, everything works ok, but when i use with above class, i get nothing. Inside AdapterView.java there is code for those click, longclick, etc events... so why can't i just fire them? Maybe i'm misunderstanding basic things on how AdapterView works? Should I extend other base classes instead? And why? Hoping to find more experienced guidance on here, thanks in advance.

I have used RelativeLayout for a custom implementation of a ListAdapter and I am not sure if I can continue using this or if I need to use TableLayout. In the first example I have the text positioned as I would like by using one image view and one text view containing the book name and the author name. However, I want to style the author text differently so I think I will need two text views. In the second example I have added another text view but it floats to the right. Second eg is Clipboard02.png. How can I make the second text view go under the first text (as in eg 1). I have done this in code rather than using XML layout.
http://carriehall.co.uk/Clipboard01.png
LinearLayout.LayoutParams skyParams = new LinearLayout.LayoutParams( 70, LayoutParams.WRAP_CONTENT );
ImageView skyControl = new ImageView( context );
skyControl.setImageResource( R.drawable.the_eyre_affair );
addView( skyControl, skyParams );
LinearLayout.LayoutParams bookParams = new LinearLayout.LayoutParams( LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
bookParams.setMargins( 5, 10, 5, 10 );
TextView bookControl = new TextView( context );
bookControl.setTextAppearance( context, R.style.SpecialText );
bookControl.setText( book.getTitle( ) + "
" + book.getAuthor( )); addView( bookControl, bookParams );

I have a ListView populated via a CursorAdapter. I give my user the ability to alter the data in the list. For example, the user can mark a row as being unread (the data are messages).
Suppose my user marked a row unread. Would a proper implementation mark the row in the database as read and then requery the Cursor?

I want to be able to show the Battery Info activity in my app, which shows things such as the exact level, battery health, etc.I'm not sure how I can get it, though a few applications such as Power Manager, Any Cut, etc. show this screen as well. I found in the source code of Settings this intent in a file called testing_settings.xml,But I don't know how to use it. I would guess from the fact that Any Cut has a list of activities, that a list of said activities exists somewhere, and therefore an easy way to access them exists, but I haven't found it.

I am rather new to android. I have the Samsung Galaxy Note II (AT&T), and i have not rooted it or put any custom ROMs or whatever onto it. i have been using the music player app that came with the device. (not the google play one that looks like headphones, the app that i use is a blue and white circle with a blue play symbol in the middle and a green musical note on the right side. just for reference) i just added a playlist, expecting the songs to be in the order that they were when i made the playlist in Kies. however, they were actually in alphabetical order and had numbers next to them (01, for example). i would like to be able to change the order somehow, or sync it so that the songs appear in the order they are in on kies.

When I purchase something from the market, it hangs on authorising payment in the market app. In the meantime the payment is taken from my card, I get an email with receipt for the order, then the market will error with the message "You will receive email when your purchase is resolved". The app then seems to freeze in a state of permanent purchased but not delivered. 24 hours has passed and I can still hit the refund button and process a refund.
This happens both on my Xoom and SGS2 whether purchased from the market on the respective device or from the website. The entries on Google wallet appear to be the same as previous successful purchases just without the delivered/shipped detail on them, and the message this item will be automatically downloaded to your device is absent.
I'm stuck in hospital at the moment and my tablet and phone are all I have, so this really sucks.I have tried multiple payment methods with no success.

I am configuring a tablet for my grandparents, and I am struggling to find an Android keyboard which arrange keys in alphabetical order (A B C D ...) instead of QWERTY.
I am not looking for a keyboard with combined keys using dictionaries like dialpad/T9 (which would be too complicated for them), I just need a basic keyboard with one virtual key per letter.
I thought that this would be very common and easy to find, but it's not The only applications that I found are :
Keyboard for Senior Citizens : would be perfect but does not scale up correctly on tablet.
Keyboard for Dyslexics (lol) : seems to be exactly the same as the "senior" version, did not try because it s an other pay app and has same developer, screenshots and description.
Kids Keyboard : Scale problem in landscape on tablet : too small.
Alphabetical Keyboard : takes the whole screen in landscape on tablet.
Simple Large Button Keyboard : Scale problem in landscape on tablet : too small.
SlideIT English - ABC pack : layout addon for SlideIT keyboard, but I don't like the suggestion panel remaining on the top.
Dextr Alphabetic Keyboard : the only functional from the list, but I would rather use a design closer to a traditional keyboard.
If any better keyboard with ABCD order or a keyboard which would let me customize the layout, I would be very interested.
