Android :: Android Create Activity Within Process?
May 26, 2009
I'm developing a photo editor application. It will launched by android.intent.action.EDIT intent. I made two application to emit that intent. I found that two instance of my photo editor activity is created within the same process which is named as my activity. But there is a singleton class used in my photo editor activity and that two activities use the same singleton class instance which break my application logic. I wonder if there is any way to let Android create my activity within the process which the launcher activity lies in? So that the two instance of my photo editor activity can be separated into two different process. And so they can reference to different instance of.

Whenever the memory needs to be reclaimed, the process is being killed by Activity Manager Service in killPidsForProcess. I have a back button in my activity window on right corner of the title bar.
I want to kill the activity completely on clicking the close button. Can I reuse the same function and will it have any major effect? Please help me out in this.

My app is comprised of a set of reusable Activities that other apps can reuse. For various reasons, I would like my Activities to be launched in context of the invoking Activity's process, instead of always being launched in my Activity's process (default behavior on Android). How can I achieve this?

Instead of installing another program I would rather just use Astro's process manager, it works plenty well for what I want now.I know you can use Anycut to rename and create shortcuts to most things, but is there a way to create a shortcut to a function within a program? If not with Anycut, maybe a different program?

I'm working on a litte HTTP server application for the Android. Now I like to secure the communication by using SSL. But I got stuck by creating a suitable keystore file. Searching the archives I came to the conclusion that it will be best to use a BKS type keystore since all other keystore types (like JKS) are not supported on the android.
Unfortunately I can't figure out a way to setup the keystore file. I tried OpenSSL - wrong keystore format. I tried the keytool from JDK - right keystore format but it doesn't support BKS keystores. I tried the Keytool IUI - I could create a BKS type keystore but it alwais ends up in an InvalidKeyException "Illegal key size". No matter if I try to create a new certificate or import it from a JKS keystore. (I tried to create the RSA ver.3 certificate with a key size of 2048 and 1024 bits.) How do you create BKS keystores?
For completeness here's the code I trying to use for loading the keystore:..............................

When a TabWidget is using intents to designate the target Activity for each tab, is there any special handling of those Activities on the Activity Stack outside of the default operation? For Instance, if my app has tabs A, B, and C, and I click them in this order--A, B, A, C, A, B--how will the Activity stack change? My understanding of the default operation, if startActivity() is called each time on the intent, would have the Stack keep loading up new instances of the activities: A, AB, ABA, ABAC, ABACA, ABACAB It's hard to believe that's how it works though... Seems like it would be a waste of resources and could be endless. Can anyone tell me how this will actually work?

In order to keep some native code happy, I need to launch an activity in a new process. Does anyone know how to do this?
I can set the activity's process attribute in the manifest, but this will cause *all* instances of the activity to appear in the *same* process, which I can't have.
I'm willing to use internal APIs for this, and I've found Process.start(), but it's not at all clear how this is supposed to be used.

Suppose my application P started Activity A, and A started Activity B, then the activity stack contained A and B, with B at the top.
After that, I opened other apps by pressing Home button. Suppose after a while, the process of application P is killed by the OS. Then, I press Home button to select application P. At this time, which activity will be brought to the front, Activity A or Activity B?

I'm working on establishing a two-way communication between an Activity and a Service which runs in a different process.
Querying the process from the Activity is no big deal. But I want the process to notify the Activity on events. The idea behind it is this: the service runs independently from the actual app. It queries a webserver periodically. If a new task is found on the webserver the process should notify the activity.
I found this thread over at AndDev.org but it doesn't seem to work for me. I've been messing around with BroadcastReceiver. I've implemented an interface which should notify the Activity but the problem is that the listener is always null since the Broadcast from the process is done via Intent, hence the class that extends BroadcastReceiver will be newly instantiated.
How can I establish a 2-way communication? This has to be possible.

My application calls Runtime.exec() to launch an executable in a separate process at start up time. I would like this child process to get killed when parent activity exits. Now I can use onDestroy() to handle regular cases, but not "Force quit", shutdowns from DDMS, or kill from the console since those don't run onDestroy(). The addShutdownHandler() does not seem to be invoked in these cases either. Is there any other hook or signal handler that informs my activity that it's about to get terminated? As an alternative is there a way to have the system automatically kill the child process when the parent die?

I have an application consisting of two activities (call them Display and Preferences) and one service which listens for incoming phonecalls. When it detects one it launches the Display-activity with a delay of 3sec in order to let the PhoneApp launch first. The Display- activity is transparent so the user can still use the PhoneApp as normal (ie answering the call) even though my Display-activity is "on top". So far so good
Now to my problem. Lets say that the Preferences-activity is active when there is an incoming call. The PhoneApp is launched on top of the Preferences-activity as expected. However when the Display-activity is launched the Preferences-activity pops up as well, hiding the PhoneApp. My question is if it is possible to work around this in some way? Since I do not want my Preferences-activity to block the PhoneApp and hence making it impossible for the user to answer the incoming phone call.

My app is made of two activities, A and B. I'm considering this sequence of steps: Activity A is started. A launches B [A is paused, B is running]. B launches a map intent [A and B are both paused now]. Now the user is using the maps application and the system decides it needs more memory. Can the system kill only one of my activities for memory, or will it always kill all activities in a "process" in this situation?
Both activities share some static data like:
class Data {
public static String mName;
public void save() {
// write to file: mName;...................

like many others, I want to kill my Android application on "exit" button. Really kill, not just move to background and stop all active code. (I know very well that Android does not like it.) I found Process.killProcess(Process.myPid()); and System.exit(0) which both work fine (I have no problem with activity stack, the "exit" button is in my base Activity.). But there is a problem. When I kill my process and I am back in the shell, I press [Home] button. It shows list of applications that are on the background including my application which has been killed.
Is there a way how to do both: 1) kill the process and 2) remove it from the Android application list that is shown after user presses [Home] button? Thanks for all replays (with the exception of that stupid "you should not exit applications explicitly on Android"

When you do a Thread.currentThread().getId(), is the resulting thread id scoped per process or scoped to the current Activity/Service?

I have developed an App that launches and works fine on Android 1.5 and 1.6. When I try and use it on version higher then that the app's activity starts, progress dialogs pop up and I can see my Async Task executing and the info being returned via Logcat. No errors or exceptions are shown. But the Activity never displays. All I see is the progress dialog showing over the home screen and then nothing. The process is active and running under the DDMS view.

I am working on developing an app and I am not sure when should I use a new activity and when should I update the existing view.
For example, lets say I have a view that shows a multiple choice question.Now, when the user selects his choices and clicks on say "Evaluate", I want to show the same question view but along with the right answers and explanations for each option. So does that mean, I should send an Intent upon a click on Evaluate or I should just update the view (i am not sure how)?
If I send an intent and show a new screen, how can the user go back to the next question without displaying the answers? If I don't create an new activity, how can I update the existing view that is already displayed?

Here's my use case: The app starts at a login screen. You enter your credentials and hit the "Login" button. Then a progress dialog appears and you wait for some stuff to download. Once the stuff has downloaded, you are taken to a new activity. Exactly which activity you are taken to depends on the server response.
Here's my problem: If you go HOME during this login/download process, at some point in the near future your download will complete and will invoke startActivity(). So then the new activity will be pushed to the foreground, rudely interrupting the user. I can't start the activity before I start the download, because, as I mentioned earlier, the activity I start depends on the result of the download.
I would obviously not like to interrupt the user like this. One way to solve this is to refrain from calling startActivity() until the user returns to the app. I can do this by keeping track of the LoginActivity's onStop() and onRestart(). But I'm wondering, is there any way to create the activity while it is in the background? That way the user returns to the app and he is ready to go. otherwise he would have to wait for the new activity to be created (which could take some time because the new activity also has to download and display some data). Update: Guess what? I LIED! I could have sworn that starting this activity was causing it to come to the foreground, but I went back to test it again and the problem has magically disappeared. I tested in both 1.6 and 2.0.1 and both OSes were smart enough not to bring a backgrounded task to the front.

Once upon a time (Android 1.5 and earlier), when you would create a new project using the "android create project" command, it worked well -- you had an app that could immediately be compiled and installed.
Now, though, when you run that command, a number of places need fixing up, where ACTIVITY_NAME shows up instead of the activity name specified...depending on the API level you target.
For example:
CODE:............
leaves ACTIVITY_NAME in:
CODE:..........
If I change the target to 1, 3, or 4, it works as expected. If I have the target as 2 or 5, it gives me the ACTIVITY_NAME.
So, I'm curious to know if:
a. This is a bug, or
b. I'm missing something (despite this example coming straight from the docs), or
c. I've lost my marbles

I've gone through a few guides and tutorials, and they're quite clear on how to start an activity (with intent). However, how do I create a new activity in Eclipse? I can probably do this by hand by then I have to modify the R file which is auto-generated. I can create a new XML layout.

Sometimes the DDMS in the Eclipse not listing the process.
To do the debug in this condition,
1) Is their any way force the DDMS to list the process?
2) Any command to attach the process from the command line?

At a certain point in my program, when I'm completely done with my service, my activity executes unbindService() and stopService() -- yet the process persists. I can tell that it persists because I run "ps" in "adb -e shell":
CODE:.............
"adb logcat", I can show you the sequence of events:
ACTIVITY: context.unbindService(serviceConnection);
SERVICE: onUnbind();
ACTIVITY: stopService(serviceIntent); & returns true!
SERVICE: onDestroy();
First, my activity calls unbindService(serviceConnection). According to the documentation, unbindService() will "Disconnect from an application service. You will no longer receive calls as the service is restarted, and the service is now allowed to stop at any time." So that is fine, and it is happening.
Appropriately, we see the onUnbind() call happen on the service side. According to the documentation, onUnbind() is called when "all clients have disconnected from a particular interface published by the service." So this confirms the correct service connection is being passed, and that the service is responding accordingly.
Next, my activity calls stopService(serviceIntent), and returns true. According to the documentation, stopService() does the following: "If there is a service matching the given Intent that is already running, then it is stopped and true is returned; else false is returned." Again, this is happening and returning true.
In response, the service's onDestroy() method is called. According to the documentation, onDestroy() is "Called by the system to notify a Service that it is no longer used and is being removed. The service should clean up any resources it holds (threads, registered receivers, etc) at this point. Upon return, there will be no more calls in to this Service object and it is effectively dead."
At this point I expect the process to disappear from the process table. Yet it remains indefinitely. But why?
Also, the process is so persistent that I can bind to it again, and I see that it is the same exact process responding because the PID (process ID) is the same!

So, I decided to give Tridents ROM a try about 10-minutes ago.
I used ROM Manager, backed-up my old ROM, then downloaded Velocity 0.2.
Now, my phone will do nothing, it turns on and shows the red Droid eye, then when it's time to go to the home screen I get pop-up after pop-up saying that "The process com.android.phone has stopped unexpectedly. Please try again."
I have no way of getting on my phone at all, what can I do?

I Just installed a new theme (Live Wire) for my Lithium Mod Rom. Don't know if there is a connection, but when I need to update an app, I get the message something like "process android media process stopped unexpectedly" and it will not allow the update. Everything else works well. I have turned it off for awhile, and have done a battery pull.
