Is there a robust way to detect if Thread.currentThread() is the Android system GUI-thread in an application? I would like to put some asserts in my model code that asserts that only one thread (eg the gui-thread) accesses my state, to assure that no kind of synchronization is necessary.

I have an AIDL service that is intended to be used by both out-of- process remote users and in-process local users. As a result, my common interface methods will either be invoked on the UI thread or in a binder background thread. The logic between the two is not the same. How do I distinguish between these two cases?
View 4 Replies View RelatedHow can I implement a run() method of thread if I create a Thread Global?
I mean If I create a Thread Globally then can I implement its run() method {" public void run()"} anywhere in my Application?
In the run() method I have to write the code to perform some action.
IF I can do it then please can anyone show me briefly how to do it particularly.
I am writing an application in which i need to handle messages between the main thread(the deafult UI related thread) and the user created Gamethread.
The requirement is like this.
An activity(say "Activity_X") is setting the view by "setContentView(some "View_Y")". In "Activity_X" i have implemeted "onCreateOptionsMenu()" and "onOptionsItemSelected()" fucntions for creating menus & a switch case for action to be taken on selecting those menus.Menu has items like "resume/pause/zoom/" .
All action to be take on selecting these menus are implemented in "View_Y" in a separate Gamethread by extending "Thread" class.
So whenever a menu is selected in "Activity_X" i need to send a message to "View_Y". And on receiving this ,a particular action/method should be called in View_Y(GameThread).
How can i achieve this using Handlers?Is there any other way of doing this? Please do share with me some code snippets for these.
I have a separate thread running to get data from the internet. After that, I would like to update the ListView in the main thread by calling adapter.notifyDataSetChanged(). But it does not work. Any workaround for that?

I was told to do this but don't quite understand why that would speed things up. Is it GameView that should implement Runnable?

View 2 Replies View RelatedI have ported the Android to a x86 platform. And i want to detect the USB plug-in.But follow the information about the android.intent.action.MEDIA_MOUNTED in the SDK's DOC, i can't receive the event of the USB's plug-in. i have checked my code and it can receive the other event ( ps:intent action) .
Besides, in the CLI, i could mount the USB device to /sdcard but it couldn't mount automatically. have seen some source code about the mount and mountlistener and it should be effective. my SDK's version is 1.5.
I would like to have my code run slightly differently when running on the emulator than when running on a device. (For example, using 10.0.2.2 instead of a public URL to run against a development server automatically.) What is the best way to detect when an Android application is running in the emulator?
View 9 Replies View RelatedI want to incorporate some Accelerometer code into a Android application im working and want to see if this is possible. Basically what I need is for the code to detect car acceleration motion. I am not wanting to determine speed with the code but just distinguish if the phone is in a car and has accelerated motion (Hence the car is moving for the first time). I have gone through many different accelerometer applications to see if this motion produces a viable profile to go off of and it appears it does. Just looking for something that popups a "Hello World" dialog when it detects your in the car and its moving for the first time down the street. Any help would be appreciated and a simple yes or no its possible would work. I would also be interested in compensating anyone that is capable of doing this as well.
View 2 Replies View RelatedI need to implement HorizontalScrollView which is scrolled to predefined positions (similar to Home behaviour). It works with slow gestures, but does not work with neither flings nor arrow key press.
I hooked to View.onScrollChanged() and it is called when scrolling happened, but I can't determine when scrolling animation ends.
In theory there should be a way to say that fling movement is over. Is there such API?

View 1 Replies View RelatedIs there a way to get a system notification when an app has been uninstalled?I would like to maintain a table of all clients' info currently using my app. However, that seems impossible if there is no way to detect this event. The first solution I can think of is to have an always running service in the background listening for android.intent.action.PACKAGE_REMOVED. But then would that service be killed once the uninstallation process has ended, or would it be stopped just before the process has kicked off? Also even if this is a solution it's has the potential to put off a lot of people when they realise that part of the app is running in the background.
View 2 Replies View RelatedI've asked "how to detect home screen" before. I'm still searching. I noticed when I press "home" button on Android emulator, I got this statement in catalog so I went to ActivityManager to see if I can find a clue there. Here is my findings: 1. I can not instantiate ActivityManager because it's constructor is not public, and it's not a singleton 2. it has a function called: getRunningAppProcesses sounds promising -- would it give me all the running processes? 3. since I can not instantiate ActivityManager I tried to use one of the derived class: RunningAppProcesseInfo to see if I can use it's parent methods: getRunningAppProcesses. Nope.

I am looking for a way in which I can detect any tap on the screen (not just in my app), I don't mind not having the information of what the tap was (control/letter), just the fact that a tap was made will suffice for me for now. Is there any possible way to achieve this?

View 3 Replies View RelatedIn my application I need to react on APN changes (including going back and forth between WiFi and GSM connections) and change proxy settings in case it needs to be taken into account to connect with the network. I'm listening for ConnectivityManager.CONNECTIVITY_ACTION broadcasts to check for APN changes which contains 'reason' extra among others. Unfortunately the 'reason' for APN change is not documented, maybe it should not be used? I was using (with limited success) reason:apnChanged and reason:apnSetupComplete as indicators of APN change being done but that does not work well with going back and forth between WiFi and mobile connection. What is the correct way of listening for changes of current network APN/Interface?
