[android-beginners] Text box +radio menu(pop-up)
Hi, I had a general UI question, I didn't find this in many applications on Android and I was wondering if it is possible to have a text box( For some text input) in the radio menu which pops up if one is having a list to select from. Any feedback would be much appreciated. In case you guys feel a sketch or a pic would be helpful to explain what I am asking I could do that as well.

Thanks. I was thinking of a quick entry box according to the list items, It was a one click process on I-phone.

[android-beginners] Geo-tagging and OCR
Hi, I am trying to make a small prototype, which would involve taking pictures and then using some scanning mechanism like OCR to scan the text on the picture. After OCR processing a screen with a some text boxes with the geotagged present location of the user would be present on one of the text boxes. Do you know of any resource where I can look into some example code. I looked into some existing discussions for geotagging but it seemed quite complex for a beginner like me. Is there any resource which can help me a beginner like me in the idea I am trying to make. Thank you in advance. -- You received this message because you are subscribed to the Google Groups Android Beginners group. NEW!

[android-beginners] App installation
I asked a question yesterday about a application I am trying to make based on OCR and some other points. I tried to look for applications which have individual elements like current location finder, Camera capture etc. I tried to install individual elements after modifying some source codes, but I am not sure how I can install on my phone. I made a apk file, sent it to my e-mail as a attachment( since I don't have a key ), downloaded it and then through Astro file manager tried to find it but it never shows even if I try to search the application. I guess we need a sd card to install a application, is it possible to install applications if we don't have a sd card? Some help please.

[android-beginners] Duplicate case problems
Hello All,
I am trying to work on the notepad tutorial on the Android website. I
tried incorporating a menu function to see how I can try to use
mutiple functions. I keep getting errors of Duplicate case for the
switch cases like Menu_1, insert_ID. Does any one knows what are some
of the things I could do to avoid these errors please? Thank you.

[android-beginners] Re: Application crashing
Hello everybody. Thanks for the suggestions. I guess the problem is I am learning Java as well and at the same time I am learning Android. So it's sort of hard for me to follow the conventions and the syntax. But I do try to look into the existing questions related to the topic. I will certainly try to look more in depth in future to avoid redundant posts. Thanks everyone On Jun 23, 12:21 pm, Justin Anderson janderson@gmail.com wrote: One other thing to mention... These groups are not only great for posting questions but also for searching through them to find other posts with the same problem or question that may already have an answer. In particular, your question is one that has been answered many times over and a quick search for Force Close or Crash probably would have given you several posts with the same answers that Mark and Simon gave. Not only does it prevent the group from getting bloated with duplicate questions, it can also help improve your development time because you don't have to constantly wait for responses to your questions.

[android-beginners] Which Applications are most famous on Android
I am making a report on Android vs other smart phone comparison. One of the comparison is to look into 10 top applications on Android and other smart phones like I-phone. This comparison should help me answer if Android is geared more towards gaming or some other category of Applications. I visited the android market online and it has top applications section but it's divided into each category and I wasn't able to get hands on some article which spoke if Android is geared more towards helping developers make games ( or any other category of applications) more easily or is it having more user friendly features for the end users to play better games. I think I am focusing more on the present models out there in market like droid incredible. Any help in terms of links or opinions would be very appreciated.
