What are the requirements for two similar device's kernels to be interchangeable?If they have the same soc,same screen resolution and same amount of RAM,the kernel should be intercompatible,right?

Can someone explain a couple of very simple concepts to me - I'm interested in mobile devices running android and how they are identified over networks. Some scenarios: Device is connected over WiFi - presumably the device has a standard IP address as with any host and can communicate with any other android host over TCP/IP (assuming it knows the participating device's IP? device is connected over bluetooth - how are devices identified in this case? device is connected over mobile operator's network - this is the one I'm interested in and confused by - is there anyway for two or more devices to discover each other and communicate via the mobile operator's network? How does a device communicate with a backend server in this scenario? In other words, how do apps and devices communicate when not connected to a WiFi network?

I just updated my app to use 2.1 api's instead of 1.6; maybe this will make a difference? I upped my min version requirements to 7. My question is how can you make sure your app works on all phones and not just the phone your are building and testing on? Is there a way to emulate a particular device?

What do you think is the best ROM at the moment and why? To qualify as one of the best it must be stable not a stable build but stable that theres not a crazy amount of force close or reboots and no other significant problems. Also post what kernel you are using with it.

View 1 Replies View RelatedJust say I have two applications, each with one activity running on separate processes and I want to send a simple string between them. For the purposes of this example, let us say I have a button that sends whatever is typed into an EditText view to the other application where it is then displayed. Do I have to expose a remote interface via a service that co-resides between the two applications? Or can I do something simpler (is there a way to pass data between processes without defining your interface using AIDL)? Thanks for clearing this up for me, as I seem to be struggling with performing IPC at the moment. I'm pretty sure I have to use the Android IPC path and generate a remote interface using AIDL. I'm just not sure about the binding to service part.
View 7 Replies View RelatedHere's the deal: I have an Android application that needs to call a web service every X seconds (currently 60 seconds). This application has multiple tabs and these tabs all need to interact with the data themselves. One is a MapView, one is a ListView and then the third is irrelevant but will need to also get some global data eventually. The issue is that I want my main activity to have a thread that runs in the background, gets the results and then instructs both child activities in the TabHost to update themselves with the latest data. Also, when the user clicks on the tabs and the onCreate/onResume activities fire, I would also like to force a redraw by getting the latest data from the main activity. I'm really at a loss here. I've tried this with a service and some ghetto static methods to pass an instance of the Activities to the Service to call specific functions to update their views whenever the timer fired, but the slowdowns were pretty bad and the code was just ugly ugly ugly.
So I implemented it as a timer-driven thread in the tabhost activity and then I have timer-driven threads in each child activity that then grab the data (in a synchronized fashion) and update their map/list. It's much faster but still feels slightly hack-ish, especially the part where I'm calling a custom function in the parent activity like so:
((MainActivity)getParent()).getNearbyMatches();
This adds an element of strong coupling that I'm not entirely thrilled with, but from a performance standpoint it's much better than it was. I appreciate the answers that have already been given and will do a bit of research on the content provider front but I'm not sure I want to go back to the service model.
I'm having an issue with inter-process communication with a Service and Notifications
The structure of my application is as follow: - ListActivity (TunnelDroid), once the user presses a listitem it will start a Service. The ListActivity is binded to the service for intra-process communication
- Service (TunnelManagerService): running in the background. This service will add a (permanent) Notification in the statusbar. Using a Handler I sometimes need to communicate with the ListActivity (to show GUI Dialogs)
- Notification: Once this notification is clicked it should open the ListActivity.
To add the action when the user touches the notification I use the following code: notificationIntent.setClassName("net.sourceforge.tunneldroid","net.sourceforge.tunneldroid.TunnelDroid"); Then I use the intent to create the notification.
Unfortunately a new Intent is opened. When I press the back button the original ListActivity is shown. So I have two instances of my same class/list.
How could I make sure the original ListActivity is opened when the user touches the Notification?
It's OK for me if the original ListActivity was previously destroyed, but I cannot have two instances. The problem is that the Handler in the Service has a reference to the ListActivity (PARENT_ACTIVITY), so if another instance is created I have invalid references. I could overwrite the PARENT_ACTIVITY, but then when the user presses the back button I have an instance with no correct link to my Service resulting in a crash/nullpointer.
The complete source can be found here: http://tunneldroid.svn.sourceforge.net/viewvc/tunneldroid/tunneldroid. Attached you can find a drawing of (most of the) inter-process communication. Could someone point me in the right direction?

I'm sick to death of my iPhone. It's been playing up to the point that using offline apps is about the extent to which I can use it half the time - calls drop/don't come through, messages don't send & the phone doesn't receive them either, the connection to the internet (Wi-Fi & cellular) suddenly drops & doesn't return unless I restart the phone...
I'm due an upgrade on my contract, and the two options with the right plans are the Samsung Galaxy S3 & Sony Xperia T, both of which have a reputation of being decent, if not fantastic phones (one more so than the other). I definitely want to go to android rather than stay on with another iPhone (which is another possible option), but I'm worried about it's compatibility with my computer.
I own a 2006 iMac which is currently running Mac OS X 10.5.8 (Leopard), which, despite only being released a few years ago and is more recent than Windows Vista, has been declared obsolete & is no longer receiving updates for any software (Flash, iTunes, Firefox, Chrome, etc.), so I'm concerned as to what may happen if I choose to switch to Android. I'm already struggling to keep my iPhone working well with the computer because of the fact that I can't even update it's software any more.
I do intend to update the software to Snow Leopard, and possibly Lion depending on whether my mac will accept it or not (the apple store assistants didn't really know anything about the 2006 model, one of whom didn't even know that the older white design existed -.- ). However, I'd like to get my phone before I upgrade.
1) Will my computer's current software (and future software) be able to effectively sync my android? & yes, I know this will require some third-party software to assist.
2) Which of the two phones would be better? My intentions are for browsing, social networking, texting, and listening to music.
I had a Huawei X5, and switched to a Huawei Ascend P1. Both have the same screen dpi, 240 and I have not changed it. However, the P1 has a higher resolution. That is the only difference I can find for this problem.
I can see and install all my apps from google play on the X5, but on the P1 they don't appear. On the web page it says it's incompatible and if I try to install the apk directly, it also does not allow.
What compatibility check is it failing? One example is google googles, I can install it just fine in my 7'' tablet and in my X5, but not in the P1.Is there anything I can do to bypass this check?
Do you think it could be rom related (I use official miui for the P1 and unofficial miui for the X5)?
Is there any manual / tutorial / guide related to compatibility of Android configuration files (build.prop, for example) between different android versions (ICS and JB for example)?
Is it possible to use optimized build.prop (or it's fragments) from JB inside ICS?

View 1 Replies View Relatedwhere I have got right now on my phone, which is:
1. I updated to stock 2.1 using the sprint update tool.
2. I followed the video tutorial to root the phone
3. then i used joey's page (http://www.joeyconway.com/sdx/custom/index.php) to install the his kernel (joeykrim-SDX-kernel v2.0.4 (includes root)).
I have done nothing else to the phone but this and removing a couple of bloatware apps (i checked the list of permitted deletions before i removed anything.) I have not installed a new recovery..at least i dont think that I did as part of one of the other operations I performed (as an aside, i am not really sure what the custom recovery is or what it is used for, so i didnt install it...i guess i need to read up more...)
So that is where I am..but i have a couple of questions.
1) i am now having issues with my wifi connection - the signal reception is very spotty in areas where i should have atleast 2 bars of reception, and the wifi often cuts out completely....Is there any know corellation between joey's kernel and this wifi issue? I have searched the forums and have found nothing that answers this.
2) Is there an easy way to get back to the stock kernel? I have read that i can get back to stock everything by using the sprint download center where I did my original 2.1 update. But is there a way to get back to just the stock kernel without wiping the phone?
Is it possible to run multiple apps at the same time on Android? I have an app that has two separate layers and which they are normally launched separately. They open sockets and talk to each other via those sockets. I am not sure if this would be possible under Android - may be generate two separate projects and their corresponding UIs and then launch them at the same time. If that is not possible I am assuming I will need to launch them from the same UI - their interprocess sockets should be able to connect to each other. Is this something that is worth pursuing?
