I have a little idea of the Utility Classes with a slight doubt on demand.
If I use a Utility class in my Application than to use that class in my main Activity do I have to create the object of that class or I can directly Import that class in my main activity?
In the nutshell, all I want to be clear about is that basically how can I use the utility class in my Main Activity?

As HTC device it is a reference model for Android ecosystem; it will run system version 2.0; it has fair features/price ratio.
Are there any arguments against Hero? Or maybe there is another handset more suitable for programming classes?
I have made apps for the iPhone, but want to also code for the Android but want to know if it is first worth my time, second worth my having to learn another language, and third worth the effort in the sense that am I going to make a profit from this.

Moreover, after signing the application when I try to install the application it gave me "com.satloc signatures do not match the previously installed version; ignoring!". To remove this error I tried -wipe_data. After doing this I again tried to load the application with adb install SatLoc.apk but it again gave me an error this time it
DDM dispatch reg wait timeout Can't dispatch DDM chunk 52454151: no handler defined Can't dispatch DDM chunk 48454c4f: no handler defined pkg: /data/local/tmp/SatLoc.apk Failure [-12]
What is this and how to remove this? I want to load the signed application in emulator. Is zipalign necessay for this purpose? If yes then from where can I get zipalign utility.
I've got a common use-case wherein a user selects one item out of many (say, on a spinner or autocomplete list), then enters the data. For example, let's say the user selects a country. Ultimately, the data I want is the country code, not the country name; but the users will want to select based on name, not code. To put it another way, user's will select "United States", but I ultimately want that to translate into "US".
There are a lot of countries. Is there an easy way to setup a mapping in Android to hash from the name to the code? I've thought of a few solutions, none of them are quite satisfactory in my mind:
A database containing country/code, which I can query on. Setting up all countries as strings in strings.xml, then retrieving the resource by name. Creating a huge Map in code and using that. (This is the least satisfactory answer).
Find a lib which can provide url parsing/building functionality which can be used with Android platform. Character escaping is desired.
View 1 Replies View RelatedI am trying to use the SDK's DDMS utility to capture screens off my Droid X. I have installed the Java JDK and the Android SDK. I set up the USB driver on my Windows laptop and connected my Droid X to the USB port. Windows XP can see the Droid just fine in Windows Explorer as a removable USB device, but the DDMS utility shows no devices. Running "adb devices" in a DOS window lists no devices either. Yes, the java.exe location has been added to my PATH. Yes, the Droid is set to allow USB debugging. So why can't DDMS see my phone?

View 11 Replies View RelatedSometimes I need to provide a Context object to call specific functions, such as
Intent intent = new Intent(context, MyClass.class);
in order to start a service
context.startService(intent);
Or, provide a Context object to do a query
Cursor cursor = context.managedQuery(uri, projection, null, null, null);
If this is done in a UI class which extends Activity, that's fine.
However, If I want to create my own utility class (a singleton) that doesn't extend anything and call these functions, I don't have necessary Context object. Now my workaround is to pass an activity reference while initializing the utility class and have that reference to call those functions. I'm wondering what's the correct way to do that. It should not be reasonable to have every class to extends Context so that it can call those functions.
Following the big guide and I am at the nanroid backup stage in the recovery utility. I've got
Android system recovery utility
Use trackball to highlight, click to select.
Options:
Reboot system now [home+back]
Apply sdcard:update.zip [alt+s]
Wipe data/factory reset [alt+w]
Then at the bottom it says
E: Cant open /cache/recovery/command
Thats the full screen, nothing about backup/restore
It would work something like this
someUtility.replace ("Hello, my name is {1}. What is your {2}?", "Mark", "name");
Always seems to be running. Anybody know what it does?

View 6 Replies View RelatedWe can now do partial flashes with the CL14 SBL.... If you have not had the CL14 official update yet, you can follow these steps to get it:
Remember... THIS WILL PUT THE CL14 BOOTLOADER ON YOUR PHONE!
What you need:
Sprints Update Utility
1. Create a datatool back-up.
2. Download and install Sprints Update Utility found above.
3. Run the program (now called SWUpdater) and follow all the directions until it says "Flash Downloading Complete".
Once you have the official CL14 update on your phone, or if you already had it, and you would like to flash SDX/Joey's Kernel (and Max's Recovery), follow the steps below.
What you need:
CL14 official update
An SDX/Joey's Kernel
Max's Recovery
1. Create a datatool back-up... (Although you most likely wont need it if you are just flashing a kernel.... But JUST in case, you should create a datatool back-up if you aren't confident that you wont wipe your data!)
2. After downloading and installing Sprints Update Utility, go into the binary folder (C:Program FilesSamsung ElectronicsSWUpgradeModelsBinary) and move the CL14 file to a safe place, MAKE SURE IT IS NO LONGER IN THE BINARY FOLDER.
3. Find the Kernel you want to flash and put it in the binary folder.
Note: Now you should only have one file in the binary folder (the custom kernel). Also make sure that if the file you are putting into the binary folder says 7zip or winrar, extract it!! If you dont you will get the message "Cannot access bin folder!", and you will not be able to start the download.
4. On your desktop there should be a program named SWUpgrade. Run the program and follow all of the steps through the end. After every thing finishes successfully, you will end up with STOCK CL14, this includes the CL14 SBL, along with the custom kernel you put in the binary folder (you are root).
5. Double check that everything worked by going into Settings-About Phone, under BaseBand version you should see S:M900.8.0S.CL14, under Kernel version= 2.6.27 moment(at)momentdev, under Build number= Joey's name (or any other developer who's kernel you put in the binary folder).
6. Repeat steps 1-4, putting Max's recovery in the binary folder instead of the kernel.
7. You're all set.
(If you happen to want to flash one of Zefie's kernels, repeat steps 1-4 also.)
It wasn't a great thing to get the CL14 update before, because it was hard to obtain root. But now with Sprints Update Utility, and all the new kernels, we are able to get root with the CL14 SBL easily.
If you've upgraded to official froyo you probably know that downgrading can be difficult, especially if you have an SLCD screen. If you did a branded upgrade (e.g. Vodafone) then the old methods won't work at all.Since current rooting methods won't work on froyo this can be a big problem.I've created a tool that will downgrade Froyo to stock 2.1. It requires a goldcard if your phone is branded. The download details as well as instructions can be found here: http://forum.xda-developers.com/showthread.php?t=768256
