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.

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.
How can I check got a successful Internet connect (Wifi/3G/whatever else) I already display an error to the user if they don't have Wifi connection but how can I make sure then that the user does got 3G connection if they wish to connect to use the application without the Wifi connection?

View 2 Replies View RelatedI'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()".............

public class ServiceExampleActivity extends Activity { Intent intent; Button start,stop; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); intent = new Intent(this, ServiceExample.class); // service example is service class Log.i("-----service------", "Service Created"); }
How do I check if a background service (on Android) is running? I want an android activity that toggles the state of the service -- lets me turn it on if it is off and off if it is on.

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.
Sorry for the newbie question, but does anyone know how I can check whether an IntentService is already running? I'm starting an IntentService from onCreate within a normal Activity, and that means that if the user minimises and maximises the application, it gets called twice. I'm wondering if I need to use something like the solution here http://bit.ly/du3VW5 or whether there's a simpler way.
View 3 Replies View RelatedI have an app that starts a service, then starts another activity previously selected by the user. Everything works on my app except I'm trying to get the service to kill itself, after it leaves the other activity without it having to come back to my activity. I've looked everywhere to see if anyone knows how to peek() search() the Activity Stack from a Service. Another way of wording is to check the foreground process from a service.

View 20 Replies View RelatedI have a service that is running within the context of my application. It gets invoked at the start of the activity and then gets update when new data is inserted or deleted from the database. The problem is that everytime I start the activity , it restarts the service. As you may have guessed - not a very intuitive design. Therefore I was wondering if there is a way to determine if the service is already running before starting it. I know I can bind to the service but I do not want that since the main activity needs to exits after the database operation is completed. I know for system services, you can get the service details from the application context. How do you do it for user defined service?

View 1 Replies View RelatedI wanna background service which is looking every minute for the location.
So I created a service and created a broadcast receiver connected to the alarm service.
That works generally fine.
Now I wanna check the Location in that Service, I have a Service which is looking first for "gps" and if not available then for "network" location. That works fine!
Now my confusing case: If I am at home and connected to the WLAN the Location is found every minute and give me an notification in android bar all is fine!
But if I am on street and go around it doesnt work. The Service is just running when I touch the screen and make it active, then the service starts and gives me the location.
Why the service just works at street when I have the screen active? And at home in my WLAN it works always even the screen is not active.
I do a ((Context)thingy).bindService(...) from within the onCreate callback of an Activity. I've observed that the onServiceConnected() callback of my associated Service Connection does not execute immediately, but rather, is delayed until after the Activity resumes, or more precisely, after return from the onResume() callback of the Activity. I discovered this the hard way (through a null pointer exception) because I was unable to use the Service (I call a method in the Service to start a Thread) immediately upon return from the bindService () call.
I assume this is normal behavior, but I don't understand why, and I further assume that there is a good reason for it and that I would benefit from understanding it. I'm guessing that maybe the Service isn't eligible to run because there are fewer than 1 processes bound that are in an active state.(?) But once it starts, if I then start the Thread within, it continues to completion of its task, even if the Activity calls unbindService() and terminates first! I don't mind that behavior (it's what I want to happen), but I want to know whether I can generally rely on it. I'm seeking some wisdom from the forum. Please help me clear my fog on all these points.
This is the class that calls my Service:
public class TicketList extends ListActivity {
private ArrayList<Tickets> alTickets = new ArrayList<Tickets>();
private boolean listCreated = false;
private static Drawable background = null;
private Resources res;
private Tickets ticket = null;
private TicketConnector localService;
[Code]
Here is the output of LogCat at verbose mode while activating the TicketList Activity:
09-28 23:22:11.420: INFO/ActivityManager(795): Starting activity: Intent { cmp=org.mw88.cmdb/.gui.TicketListActivity }

View 13 Replies View RelatedI have followed the Local Service example provided by Google, but my Context::bindService(...) always returns false and there is Service Connection::onServiceConnected is also never called. I understand that Context::bind Service() returns immediately, but my Service Connection object is never triggered. I don't know if these apply My activity is running inside a tabHost and I was wondering if that can affect service binding in any way. The Service itself may have a problem, but I can call start service to the same service with the same Intent and it works as expected. Does anyone have experience with this? Please help me out.
View 2 Replies View RelatedI've looked through the other SMTP threads on here also, but didn't see anything that seemed to fit. I have a Desire and I use it over a WiFi link in my home, fine for surfing and reading mail, but when I try to set up an outgoing mail account on my 'usual' mail account I run into a problem. Because I travel a lot I use a service called authsmtp to provide me with an smtp address wherever I am, works fine, annual fee is low (not a recommendation, works for me).
However, in order to work it needs an SMTP address of the form mail.authsmtp.com and a password. I can enter the mail.authsmtp.com ok but it always says it cannot check the account. Is this 'cos it cannot check the smtp or is it something else? All the other data seems to be ok.
I'm looking for a protocol to secure a connection between a mobile device and a web service. I want to ensure that only the mobile device can perform actions on the web service and vice versa. Data doesn't need to be encrypted. I know Oauth, but it seems that it's more used to secure connections when you got 3 different entities (Server, Consumer and Auth). Here, the Consumer and the User would be the same person. Is there a simple protocol to do that (without requiring the user to login and then authorize the access token like it is the case for Oauth)? I need to use it on different plateforms, so the protocol needs to be available at least on iPhone and PHP.

Most of the time the data connection works fine. But if I go into an area with no cell phone reception for a little while, once I come out into a full-bars area where data normally works, my data connection never resumes. Once that happens, I can make calls just fine, but can't use the internet/market/etc. The only thing that solves this problem is to go to network settings, enable 2G networks only, then turn that setting off. That is a huge pain, obviously. Has anyone else had this problem? This was happening with my old SIM, so I had T-mobile give me a brand new one, but it is still happening.
