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. Also if in any way Android code is similar, then will it be hard to bring the iPhone (Xcode) files, or copy and paste my iPhone code into the Android code.

The Samsung i7500 Galaxy is, except the support from Samsung itself, a great Android smartphone with a very good (the best?) price for value. It's with 11,9mm the second slimmest Android phone after Nexus One with 11,5mm (right?) and has unlike the HTC phones a flash light and build in storage of 8GB. On most sites the Galaxy is (one of) the cheapest Android phones, I wonder if it's because Samsung is cheaper or HTC/Motorola more expensive by itself?
I personally would compare the i7500 with the HTC Hero, although in my opinion the i7500 still has a much better price for value.
Is it even possible to define if and which Android phone is a low, middle, or high-end smartphone?
Sure, it also depends for what purposes you bought and use your phone, but I still wonder were the i7500 would be if 1=low and 10=high end Android phone, and if there even is a number 10? I also think that the D-Pad is a big plus and not a minus in comparison to the scroll ball from HTC.
I want upgrade my samsung i7500 device to android 1.6 (new build).

View 3 Replies View RelatedWhich is the way to attach the custom event handlers for the activities, in case they support one, when the activity is started using Intent and startActivity() methods. Does intent has a special way to take up the handler callback references. Basically, I wish to handle call end activity after invoking the call activity.
View 2 Replies View RelatedI've more than one Handlers in an Activity. I create all the handlers in the onCreate() of the main activity. My understanding is the handleMessage() method of each handler will never be called at the same time because all messages are put in the same queue (the Activity thread MessageQueue). Therefore, they will be executed in the order in which are put into the Queue. They will also be executed in the main activity thread. Is this correct ? Code...
View 1 Replies View RelatedSorry if this thread seems inconsequential but I have been rendering myselves sleepless nights over the past couple of days ( and nights ) due to my inability to choose between the above two said android phones. I like the i5700 for its zippy 800 MHz processor and that its got the 2.1 update. I like the i7500 for its 5 MP camera and flash + a larger screen to play with I would have gone in for the i7500 but have been hearing about Samsung deciding against not updating it to version 2.1 which can off course be done taking the un-official channel. Moreover the 528 Mhz processor is certainly lagging.
But still I see people in here Going after the i7500 .... Adding to it there is more threads and discussions going around on the i7500 as compared to the i5700. Am I missing something in the i7500 or is it just that i am a stupid newbie ... I have gone through many many pages of information on this thread before posting this query.
I was wondering if it is possible to have different behavior depending on a click on the icon and the text inside a TextView... Any suggestions?

This question is related to an existing question I asked. I though I'll ask a new question instead of replying back to the other question. Cannot "comment" on my previous question because of a word limit. Marc wrote - I've more than one Handlers in an Activity." Why? If you do not want a complicated handleMessage() method, then use post() (on Handler or View) to break the logic up into individual Runnable. Multiple Handlers makes me nervous. I'm new to Android. Is having multiple handlers in a single activity a bad design ?
I'm new to Android.My question is - is having multiple handlers in a single activity a bad design ? Here is the sketch of my current implementation. I've a mapActivity that creates a data thread (a UDP socket that listens for data).
My first handler is responsible for sending data from the data thread to the activity. On the map I've a bunch of "dynamic" markers that are refreshed frequently. Some of these markers are video markers i.e., if the user clicks a video marker, I add a ViewView that extends a android.opengl.GLSurfaceView to my map activity and display video on this new vide.
I use my second handler to send information about the marker that the user tapped on ItemizedOverlay onTap(int index) method.The user can close the video view by tapping on the video view. I use my third handler for this. I would appreciate if people can tell me what's wrong with this approach and suggest better ways to implement this.
I am writing an Application that has multiple layouts with buttons. I have set up onClickListners for the buttons. Some buttons will change the activity and bring up a new layout with new buttons, and others will send outgoing SPP strings over Bluetooth. The strings will be defined in an XML file and will not change (serial commands).I can hard code the MAC address of the Bluetooth Server and only need to send data, not receive.
I am looking for some general guidance on the direction to go as far as setting up my Bluetooth connection and outgoing transmissions. I have looked at the BluetoothChat example extensively but do not have any good resources in the case of multiple activities.
-Do I use a separate activity to manage all Bluetooth transmissions and connections and create handlers for every case where I would send a Bluetooth message?
-Should I add Bluetooth connection+transmission threads in every activity (seems like i would run into issues losing the connection when changing activities)?
-Can I use handlers that are not class specific where the BluetoothService Activity could send whatever was prompted by the active/current activity?
-Could I just hard code all strings to be sent in the BluetoothService Activity and the UI activity could prompt the BluetoothService Activity to send the requested string based on the button click?
