I would like to share a cache file across activities, which are running in different processes but in a same application.So, is there any way to make it thread safe (probably not "thread safe", should we call it "activities safe" or "process safe" ?

Some times after installing my application and first running my application is creating two processes as follows.
CODE:................
I wrote a JAVA application with native methods, and trigger encoding program in native methods. That makes two processes, one is application process, another is encoding process.I would like to know if there is a way to get encoded data from encoding program and pass them to JAVA application.
View 2 Replies View RelatedI have an application with a multi-instance activity. I would like each instance of the activity to appear in a new task and process. Any suggestions on how to do this? By manipulating the manifest I can cause all instances of the activity to appear in a specific task and
process, but I haven't found any way to cause each instance to appear in a different task and process.(The requirement to have different tasks is that we want each instance of the activity to appear separately in the task list; the requirement for different processes is that each instance of the activity is backed by a chunk of native code with global state. We can't change either of these.)
I am designing an app that will have some activities separated in tabs. Some of them will have to perform tasks in the background will the user is in another tab. What is the best strategy for designing an app like this? I was thinking about using a service but it can be killed by android dalvik, isnt it?

View 1 Replies View RelatedI have advanced task killer on my phone but am amazed at the numbers of processes it seems to kill. I have the ones I know I need set not to close down like adw launcher the HTC keyboard etc however it regularly reports its closed down 40 + processes when I run it.The I run it a few moments later, not having launched anything, and it reports shutting down another 20 or so.Is this right?Could this be the cause of the lagging? I am currently running JM5 firmware which seemed amazing to start with but now seems as laggy as it was before.

View 2 Replies View RelatedWell, I decided to keep my Behold and let the ol' 2g iPhone go.Most of my stuff on this phone seems to be working fairly well. Decent battery life, nothing hangs up too bad.But, I just installed ATK and it's weird.I kill all the processes, then they mysteriously come back a little while later without being open by me.Why? Yet the available memory seems damn decent, 100 available most of the time.Also I installed LockBot And every once in a while it just wont be on my screen. It will just go back to it's original hit unlock to unlock screen.
View 3 Replies View RelatedI don't use task killers or any nonsense like that, but I keep OS Monitor running so I can see if my CPU is running when it shouldn't be. While opening OS monitor and looking at my processes I noticed last night that there were like 6 flicker processes. They weren't currently using any cpu or anything, but why are there 6? And now today I noticed there are 2 running. (after re-start / battery charge)

It would be nice if StackOverflow had a section where we could post tutorials like mine so that I can answer literally hundreds of questions that have been asked here with a single blow. See... every day I read questions about how to pass complex objects between activities, how to save state so that your app can resume after orientation change, how to update listviews when the data changes, etc, etc. Here is the second part of a tutorial series I posted on my blog... I hope that you actually read it... because I haven't seen any examples like it anywhere... and it has changed how I think about developing for Android across the board. The question is... is there a downside or negative affect of developing like this?
Beyond Smart Lists - How Observable Singletons change the game. Please read through both of these tutorials carefully... I will answer any questions about it here that I can... I really want to know what you think about this and if it might solve issues for you. NOTE TO MODERATORS: there are no advertisements of any kind on my blog.. so don't just close this because you think I am spamming somehow... I am not going to duplicate my post here.
I've been flashing ROMs built on the latest code for Jelly Bean (4.1.1). (The phone is the Galaxy Nexus LTE.)
The battery has been draining fast and upon checking with OS Monitor, I learned that a bunch of android.process.acore processes, sometimes alone and sometimes with another, have been registering high CPU loads continuously until they run the battery down.They are Contacts Storage, User Dictionary, and DRM Protected Content Storage. (DRM is probably not an acore service but it is making trouble just the same.)
I tried winnowing down the problem by deleting the contact store data and resyncing while de-activating third party syncers like HacSync. I even tried cleaning up the contacts via Google on the web. The contacts number only a few hundred. Again, the processes up claiming huge load after the initial sync period.
I scoured the web for reports but have only found mentions dating back to Gingerbread or ICS involving Facebook. Facebook sync doesn't work with JB and again, I have disabled HaxSync.
I also froze User Dictionary with Titanium Backup but that did nothing to keep the process from running, even after a reboot.
I want to run tcpdump on the NDK using Process.start() and want to capture this output to a buffer.Can anybody show me how i can do this?Also is the process created in the same Dalvik Vm as the JNI call or is it in a different VM?
View 1 Replies View RelatedAfter searching, I was unable to find any post that deals with my particular problem, and I don't know if it's a problem or something I have to deal with. On my LG Eve (unlocked, not yet rooted), when I run Task killer, I notice that there are two items in the list that look like configuration files (window with a gear in front of it):
com.tni.Task killer:Captain Obviously, the first one is linked to Task killer and if I kill the configuration file, it kills the Task killer process. When I try to kill beware.com, though, it does nothing. The file remains in the list and is also visible in the Task killer widget. (Speaking of the widget, when I kill Task killer, the icon for the 2 configuration files usually remain, even if I auto kill everything.) Doing a little searching on the tubes, I found that beware.com are the developer for Quick Settings. I don't think I downloaded that app yet, but I might have and subsequently deleted it. Is it possible that the configuration file remains after I un install an app? If so, how do I remove that con fig file?
I have an API Object that I made, and I would like to share it between a running Service and various Activities in my app, almost like if I was to make the class static. How could I go about sharing the created object between the two?
View 2 Replies View RelatedI have developed a simple android application, which when started opens a Timer. User is given two buttons, start/ pause. This is working fine.What i want to do is to add a way to support multiple timers when a user swipes his finger on the screen.When he swipes from left to right, a new timer should show up, but the previous timer should not stop. This is a way to add multiple timers.Also, when he swipes from right to left, i want a previous timer to show.This is what i have done so for. I have a timer activity. I have added a touch event on it. When, a person swipes his finger, i get the co-ordinates and decide whether its from left to right or right to left.This functionality is working fine, as i can see the appropriate log messages.The problem is when I'm trying to load Timer Activity.It just loads the previous Activity and doesn't really create a new one (I figured this from the timer).Is there any way to do it?

View 1 Replies View RelatedIs there a way I can test if there are any other activities in my app still alive? I am looking to stop a service in an onDestroy method, but only want to do this if there are no other activities from my app still alive on the stack.
I have the call stop the service in the main activity's onDestroy() method. This works perfect EXCEPT that if a user launches my app, then launches a few activities in my app, then hits the home screen and RELAUNCHES my app, they will subvert my order and the main activity will now be above other activities of my app. From this state, if they hit the back button and 'back out' of my home screen they will trigger the onDestroy() method and kill the service even though there are other activities open on the stack. I want to avoid this by stopping the service ONLY if I am sure there are no other activities of mine open on the stack.
Can we run two activities on a single screen? if so, then could anyone give me an as to how its done?
