I was wondering if would be possible to perform an action for each time the USB status of the device changes.
For example if the user plugs in the cable and it is in sync/charge mode it performs a certain action, if the user then changes the phone into USB Memory Card mode another action is performed and if the user then disconnects the cable then the another action is done.

I'm basically trying to check that the device is connected to the internet to that I can access and parse an RSS feed. This is also the 1st android app I have written so I'm still finding my way around so any help/advice would be appreciated. I'm sure the variables should be assigned to something but I don't know what. The classes don't appear to have public constructors so I can't do "WifiInfo info = new WifiInfo()".............

I'm trying to check if the phone is currently asleep in a service. It's currently a very messy implementation (I'm reading a file in the filesystem that says if the phone is asleep or awake every 10 seconds) so I'm wondering if this is possible with PowerManager or something.

I already checked the LocationListener onStatusChanged method but somehow it seems that is not working, or just the wrong possibility. So basically i just need to know if the gps icon at the top of the screen is blinking (no actual fix) or solid (fix is available)..
I have made an app that sets notifications in the drop-down status bar of Android phones. However, there is a bug in my code (sometimes the notifications are set, sometimes they are not). I want to be able TO CHECK (in the code) IF THE NOTIFICATION IS VISIBLE TO THE USER. (i.e. can the user see the notification in the status bar?).
How can I do this?
Android developers can check this code to check the network status on wifi and 3g mobile
You need the following permission to get status view source print? 1 <uses-permission android:name="android.permission.INTERNET"></uses- permission> 2 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses- permission>
What is the simplest way to check whether my app can access the internet? I am using some APIs that use the internet, but they crash if there is no connectivity. So I just want to check if there is internet access by any means.

I'm doing Major Project on my final year and I'm very new to Android plus I;m not good at codings. I need help with my login page. I've created something like a database connection java file which is this:
CODE:......................
I've already created a database for users using SQLite. The database name is Users and the table is called User. The records inside the table are Username, Password, LastName, FirstName. I've inserted one user's info into the database. The problem is I do not know whether my UserDB.java is correct.
And I've also created login.java. Hardcoded Login page:
CODE:........
So I want to know how I should apply the database connection on the login.java. Should I insert database connection something like db.Open();? I studied ASP.Net a few months back and I kind of forget most of what I've learnt.
So how should I open the database connection on login.java and how to check with database whether the user enters the right username and password?
Just incase you need my xml, here's the code:
CODE:......
I need to learn how to do it so that I can apply for other pages for example Register.java page.
I was trying to make an anonymous class to upload a file to a server.
I wanted to make that easily reusable much like some kind of component.
Everything works fine but as a final touch i wanted to add a function to check if internet connection is available.
Problem is, the call to the connectivity manager needs the Context :
ConnectivityManager connec = (ConnectivityManager) getSystemService (Context.CONNECTIVITY_SERVICE);
Since i'm in an anonymous class and I've read that it's not a good idea to pass the whole context to classes, I wondered about two things :
1 - Is there another way to check internet connection without the Context ? 2 - Why in Android internals make it necessary to have the context just to check if the device is connected to internet ?
I want to check that the network connection is alive on the phone from program but when i try to run this code
Code:
private boolean isOnline() {
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo netInfo = cm.getActiveNetworkInfo();
if (netInfo != null && netInfo.isConnectedOrConnecting()) {
return true;
}
return false;
}
I get the message "Sorry 'Appname' is stopped unexpectedly. Try again".I might have to search the solution elsewhere, i added permissions for network, run the application and got the same error but when i tried to start it from the menu it said application not installed.
Any other Tweeters gettin tired of Twidroid? The dev had it perfect, in my opinion, about a month or two ago.
Since then, there's been this odd bug where sometimes you can't update, in fact, MOST of the time you can't update normally. You have to uninstall it first and then install the new version. And their solution is just to "suggest" this in the description.
Last week they had two updates and I had to install them 3-4 times each before they would work. I'd install, have it running and get told "there's a new update!" which is actually just the same update. Now when you tap exit it asks you "do you want to clear your username, password, and cache now?" If you press "no" it doesn't exit.
Unistalling/reinstalling wouldn't be such a huge deal except you have to re-enable it, re-enter your login info, and do all your settings over. By default it saves the cache to the phone, so you have to switch it to the SD card. By default it's going to check every 5 minutes and drain your battery, by default it doesn't show full messages in the notification shade, etc, etc...
It's a shame, as it worked perfectly with statusinator (for facebook). So, I could update my facebook status in statusinator and have automatically ask me if I wanted it copied to twitter, too.
But since statusinator doesn't work with cupcake, and appears to have been abandoned by the dev some time ago, I'm looking for a new twitter client.
I'm not going to pay for a client. I find it ridiculous for someone to expect me to pay for an app that runs a free service. That's like paying someone to turn on my television and change the channels.
I'm trying BuddyMob and twittered and they're both "okay" so far. Anything that's awesome, does notifications, and has a connection for facebook status updates?

Info about when the phone was last connected to the charger? I ran across that last night (my first day with the Evo) and I wanted to look at it again since I unplugged it in the middle of the night and don't remember when I did so. I've only had the phone since about 5 pm yesterday but I've put it through very heavy use and so far I'm 'very' pleased with the battery life. Definitely better than my Hero so far.

It states that enabling this will "require more battery plus view of sky"
When checked, it states "deselect to conserve battery"
So, the question is, should this be enabled?
I imagine for some applications, knowing your precise location should be useful, especially if the turn-by-turn maps are installed and used.
I'm thinking to deselect this, and selecting it at times when I need it.
So, to check or not to check?

I'm using ThreadSafeClientConnManager to manage a pool of client connections, because my application has several threads, which are simultaneously connecting to a webserver.
Abstract sample code:
CODE:..............
Now lets say on of this threads is downloading a large file, but then the user of my application is switching to another activity/screen. Therefor the file is needless and I'd like to abort this download connection.
In ThreadSafeClientConnManager I found this method: public ClientConnectionRequest requestConnection (HttpRoute route, Object state) Returns a new ClientConnectionRequest, from which a ManagedClientConnection can be obtained or the request can be aborted.
So far I've been using:
CODE:.........
Now from what I understand, I've to use:
httpclient.getConnectionManager().requestConnection(HttpRoute route, Object state);
And that's the point where I'm stuck. I assume that for the route I can just use new HttpRoute(new HttpHost("10.0.0.1")) or whatever my server is, but what to put in for Object state?
And second, as soon as I've the ClientConnectionManager I can call getConnection(long timeout, TimeUnit tunit). But then from there, how I do I execute my HttpGet httpRequest = new HttpGet(URL_TO_FILE); as I did before with HttpResponse response = (HttpResponse) httpclient.execute(httpRequest);?
I've been gone through the documentation and tried out quite a few different things, but I wasn't able to obtain a working solution. Therefor any suggestions and/or code examples are more than welcome.

I'm coding a very basic FTP client on top of my application and I have 2 activities. The first one is the file explorer and the second one is the image viewer. Once I click on the image filename on the explorer, I want to pass the connection to the other activity to handle extra stuff. Basically, I want to keep the same org.apache.commons.net.ftp.FTPClient object (which handles the connection) alive in-between the 2 activities. I know I can't pass an object inside an intent so I don't know what my best bets are.
