Android :: Android Application Isn't Showing On Main List Of Application
Sep 1, 2010
I'm beginner of Android.I want to run my first application on emulator. I use eclipse.I don't know what's happen. I installed my apk. I "register" my acitivity in manifest file, but I can't see it in list of application. When I open manage application setting it's written that my apk is installed. I searched about it everywhere. Even in faq of Android Development there is post about but I did all this things.

I guess that Android won't let people to do this, because they think they have perfect handle for the task/applications. However, I really need to do this in my case.
I have an activity A acting as the entry point of my application. In that activity, it reads the preference and decided which activity to start, say B or C. After that, it finishes itself. So, activity A never appears to the users.
My application stores things on sdcard, and reads from it constantly. So, when the sdcard is unmounted, I need to display a message to the user that the sdcard is unavailable, instead of opening B or C. I set a check in A to display that message when sdcard is unavilable. When that message is displayed, A will not try to start B or C.
Things works perfectly if user only enter my application from application launcher. However, I found that user can also enter my application by long pressing home and choose it from the recent application list, if he has opened it recently. When user does that, it skips A and goes directly to B or C. I don't have the check in both of them, so exception is thrown while I am trying to access sdcard, and force close dialog pops up.
I can simply move my check to both B and C to fix this problem. But in the future, the number of activities started from A will increase. If there are 6 of them, I'll need to copy this check to 6 places. Needless to say, this looks very ugly, and is a maintenance nightmare.
So, the best fix should be removing my application from recent application list when the sdcard is uunmounted. However, I can't find how to do this. Even killing the process or use ActivityManager.restartPackage, it still appears in the list. Can anyone tell me how to remove it from the list?

Is there any way to hide an application icon from Android applications list ? The application should be downloaded from Market and opened some GUI for configuring my application. I don't want to see any icon of my application in applications list. User should not be able to run it.
By the way I know some way:
remove this line from manifest
<category android:name="android.intent.category.LAUNCHER" />
But it is not worked for me, because the GUI is not shown.

Is 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.

Curious to know the reason behind not allowing updating UI elements from background thread in Android. Will main thread does something more (probably interacting with framework) after updating the UI elements so that changes can be seen on the screen? Is it the same case with other GUI tool kits?

I want to hide my application icon from main menu at the run time. I believe that a filter with category Launcher in the application's manifest file is responsible for the application's presence in the main menu. Is there any way to change the category at run time? or any other way to hide the icon from main menu?

My application starts a remote service and binds to it. If I close the application with the "back" button there are still some threads running (listed in the Debug View of Eclipse) - main thread, and three Binder threads. In onDestroy() I call unbindService(service_connection) - is there something else to clean up?

I've implemented an onSaveInstanceState function in the main activity of my TabHost-based application. I need to save the state of various objects I am keeping in memory that I have all marked as serializable, as well as some basic int and string values. I have stepped through my application and watched it call the onSaveInstanceState function and presumably save everything without any manner of exception or problem. The issue is that my onCreate function is being called with a null Bundle value every time after I start the application again. I'm really at a loss and unsure why it would call the save but not pass anything into the create.

The normal phone And when I click on my app, it just opens my app. I do not understand what is causing this and do not want my app to be shown in that list.

old question: "Why does creating a Toast crash my application?" My application runs fine if I don't use toasts but if I want to create and show a simple Toast I get these lines in the log and then the app crashes.

I need help finding the right email app.The default one is horrible. The problem I am having is that it doesn't differentiate new emails from old. Every time I open the inbox in any of my email accounts, it always shows all emails as new. I don't know which one's I read or not. It's not bad if it takes me directly to the email, but when I have emails for multiple inboxes, I don't know which ones have the new email. I called tmobile tech support and was told that unless I delete the read emails from the server, the phone will keep reloading them as new. On my old phone, the messages I read where marked as read and stayed that way. When I got a new email, it was clear which one it was because it was highlighted.
Also, I've just switched to the g1 from a business phone, so I'm really new to this still. The couple things that I would like to figure out how to do is, first, I would like to know how I can search my contacts both by name or business. I've transfered the contact info from outlook to the g1 and so I have both name and business information. However, when I search using the keyboard, I can only search by name. If I put in the name of the company, it doesn't show up. Also, is it possible to have both shown. On my old phone when searched for either the person name or business name, the result showed both. For example, if I searched for lauren or Unico, it would show up as Lauren with Unico below it. Also, this way if I have more than one lauren, I can distinguish between them without having to click through each one.
Secondly, is it possible to set up "speed dial" function. Basically, if I pull up the dialer and press 2 for like 2 seconds it will. Third, I used to have my phone setup that I would have what ever my next appointment was, it would show on the home screen. Is that possible with this phone. Is it possible to allocate certain space on the home screen to preview upcoming appointments.

I have uploaded an application in Android market. But when I search for the app the app do not appear in the autocomplete box which appears below the search box. For example, if I type "h" in the search box the autocomplete box will have the applications with "h". But in my case I need to type the complete name of the application.

Is there any way to change the four main icons (I'm not sure what to call it) that appear at the bottom on every page? I downloaded Handcent to use for my SMS because I like the way it looks better, etc. But I wish I could just remove the "Messaging" and replace it with Handcent so that I have access to it from every page instead of having to click on the Handcent App every time.

I am a freelance graphic designer, and I just bought the Droid for Verizon as a tool to help organize jobs and business.
I'm looking for an application to help organize my jobs, and I think the features and abilities I'm looking for in ONE program may be too advanced, but we'll see.
I want to find a sort of To-Do list application that will let me do all of the following:
Organize Jobs by Clients and allow me to select the job, read the general description of the job. I want to be able to have an appendix to each note that will allow me to view people, businesses and contacts that will be involved in the job aside from the main client, ie Print shops, mailing houses, owners of rights to imagery, etc. I also want to be able to directly contact any of them as a link through the list note. and I'd also like to be able to have another annex section to each note that will allow me to set up a to-do list for each project, example: Illustration job list would be: Finish pencils Finish Inks Finish Colors Scan etc.
Anything out there for something like that? Understandably there probably isnt a program out there specifically for graphics jobs organization, but I am wondering if there is a to do list or general list application that has that intricate of an organizational structure.

I am new to android and have been teaching myself how to create apps through the android developers website. My app itself is like a recipe book. It lets me add my favourite recipes to a database so therefore where ever I am I am able to see what ingredients and the method for creating my favourite dishes. The list is getting rather long now so I was wondering if there was a way to search through a list like you do for contacts in your phone book.

I think that it should be possible to get all the activities from 'third-party' application, described in the manifest file. I can't figure out how.
for example: List<Activity> aList = packManager.getActivitiesForPackage("package.name");
