I am new to Android and I have installed "Advanced Task Killer" which I have noticed something that is really confusing me. If I kill all of the apps running, then check back moments later there are a ton of installed apps running in the background which I did not launch. Example: right now there are 27 apps running in the background. Can someone shed some light on this for me?

Every so often I check my memory with Advanced Task Manager and I see certain applications running in the background and my available memory has dropped quite a bit. Now I am using the HTC Incredible so I still have about 127 MB free, however what concerns me the most is why the programs are even launching themselves in the first place. I could see some application having to start themselves, like a twitter client or an email client, however one of the programs that seems to be launching itself is the eBay app. I installed the app in case I wanted to view an ebay listing however I never use the program and it still seems to launch itself. Is this an example of a poor application design (i.e. ebay app) or is there some other reason these programs are launching themselves?
View 2 Replies View RelatedSuddenly, my android phone have trouble with the issue that some of Applications close automatically right after launching, especially right after I reboot phone. What are the cause ?
After reboot, my phone still has about 200MB RAM free. however, after reboot about 1 or 2 minutes if I open Facebook,/xda,/viber ...it will automatically close immediately and back to home screen. BUT if I take the phone rest about 15mins, it becomes operating normally. No trouble with the issue that some of Applications close automatically right after launching anymore. So I don't know what's happen.
Although I have seen several threads and tutorials on this topic, I guess I still have some confusion on how an application can be chosen from a list of applications to display a file.
I have a Activity which has a list view in it. This list view is bound with file paths (so a file browser of sorts). When we click on a specific file type, I need a list of applications that can open that file.
So far this is what I have in the OnItemClick for the list item:
CODE:............
When I run this on my phone, the error is:
No Activity found to handle Intent { act=android.intent.action.VIEW cat=[android.intent.category.DEFAULT] dat=file:///
When I do the same in a file browser application (downloaded from the marketplace), I get two options (QuickOffice and Word to Go), both of which I have installed on my phone.
Could someone guide me as to what else is needed here? Things I have tried besides the above:
Add the following entries to the manifest:

I have written an application which calls native methods through JNI. In the native library 4 threads are started. On USB removal, the application is to be closed including the native threads. Upon receiving the USB removal event, we are trying to kill the threads (pthread_kill() ) and then finish (using finish()) the activity. After reconnecting the USB, the application is not launching due to memory corruption. In DDMS, it shows the threads are still attached to bionic. As the threads are not closed, I feel the resources were not released properly. If I reconnect again then application launches and works fine and the same repeats on every launch.
To solve this problem Can I use System.gc() ? Can I use pthread_exit() 1st and then pthread_join instead of pthread_kill ? Whats the procedure in Android to kill the native threads and also the application ? After the application is closed, will it not be listed in DDMS ?
I have an application with three tabs. Through various interactions with the items in the tabs I end up launching other activities. The client has reviewed this and would like the activities launched "within" the tabs, so the tabs remain visible and if the user clicks the tab it goes back to the original activity defined in the setContent function. Is this possible and how would I go about this from other activities? (ie the child activities, not the one that defines the TabHost and has access to call setContent)?
View 4 Replies View RelatedAbout 5 times now, I've noticed the TV Out application has launched, and I see the little TV icon up in the notification curtain. I have no idea how it opens, but when it does I have no audio. If I plug in headphones, I get audio through them. After headphone removal, there is still no audio from the external speaker. Also, I don't see any way of closing it. It sometimes closes on its own, but I usually wind up rebooting the phone.Anyone know how to close this app and keep it from launching? Does it automatically launch when the proper cable is inserted, or do you manually launch it.

Going through the ApiDemos sample code (in Android 2.1 platform), I saw that there are two activities that make use of the Instrumentation class: ContactsFilter and LocalSample. However, I'm having trouble finding the menu that will launch any one of these activities from the ApiDemos application. I just want to be able to run ApiDemos and hit the breakpoint in one of these Activities so I can understand how the Instrumentation class works. proper navigation in ApiDemos to launch ContactsFilter or LocalSample?
View 2 Replies View RelatedOn the market, there's an application called App Protector, which seems to effectively block the launching of configured activities until a password is correctly provided. By default, it blocks access to itself (not very interesting), Settings, and a few others. I wrote my own app to launch settings (rather than doing so through the home screen) and App Protector continued to do the job it claims to do.
When an activity that is protected is started, App Protector's password input activity is shown instead. Once the correct password is provided, the activity that was started comes to the front.
First -- does anyone know how this app is able to get between the rest of the system and the activities it protects? I would like to do something along these lines in my own application as well. Perhaps this app is receiving a broadcast about other activities coming to the foreground, and when the foreground activity is protected, it forces itself to the foreground?
Second -- does anyone know how well this technique will stand up to attack? Are there other ways to circumvent, where start Activity(...) fails to? It seems that one could use adb to un install it, thus removing its protection easily, but if I pursue my plans here, the app will be a part of a device's firmware (which, I assume, offers some protection against its apps being installed?)
I want to launch my application in market. I ahd go to http://market.android.com/publish/signup but there they are asking for Website URL. But i don't have any website then what should I enter there? or is it necessary to have our own website to launch application in market?
View 6 Replies View RelatedMy app has 4 activities on the stack A->B->C->D (top)
If you press home and re-enter the application, another instance of A is started, so the stack is A->B->C->D->A (top). I know this because when I press BACK, A is popped off and I now see D (instead of going to the Home screen).
What I want is that when the user re-enters the app, they re-enter on the same activity they were in before (D).

Is it possible to launch an app widget from another application.
For example, I have a button in an application. When I click on that button, an appwidget must be launched.
I would like to launch an app the user selects from within my application. However, I'm not sure how I'd go about doing this. I've tried this:
Intent intent = new Intent();
intent.setAction(Contacts.Intents.SHOW_OR_CREATE_CONTACT);
startActivity(intent);
But this seems to throw an error and force close my application. I also tried adding:
<action android:name="Contacts.Intents.SHOW_OR_CREATE_CONTACT"/>
in the AndroidManifest file, but to no avail.
A look at Logcat shows that it's an "IOexception - no such file or directory". A couple of questions arise from this. I read through the Android docs and noticed that the Contact.Intents class is deprecated. However, it's successor, ContactContracts is aimed at API level 5 whereas I'm targeting API level 3. Could this be the problem? Also, I've hardcoded this application into the code. Is there a way to retrieve the intents of any application the user selects so that they can be launched?

I have this error :

Have you declared this activity in your AndroidManifest.xml?
But when I replace this line
// myArray[i][0] = "com.android.settings" // myArray[i][1] = "com.android.settings.Settings" ComponentName compName=new ComponentName(myArray[i][0], myArray[i] [1] );

I am implementing a simple app. I need to start an activity based on the state of the Activity. Lets take i am using a button to start the activity.

2. If the XYZ activity is on focus, then i need to close the activity on the button press.
3. If the XYZ activity is not in focus (like onPause) state then, I need to change the button state.Can you please help me in the flags that i need to use for starting the intent. Is it possible to get the state of activity before I start that activity?
