How To Convert ASCII Character To Decimal Number In Android
Jul 28, 2013
I'm working on an Android app. I have a TextView which contains an ASCII character. This character changes every 2 hours. I need to be able to read this character and convert it to decimal number, and then write it to an another TextView. So let's say the character is "[" and it's decimal value is 91. 2 hours later this character changes to "U" and it's decimal value is 85.
what kind of code should I use in my app to be able to convert ASCII character to decimal number?

I'm compiling using android tools without eclipse.
I compile launching "ant debug" from command line.
I have found many many instructions around the web about how to remove with annoying warning, but I haven't been able to make any of them work.
I've tried -D option, I've tried randomly tweaking build.* files, I've tried exporting an environment variable... nothing.
I guess some of these methods just don't work, and some others would work but I've been doing them incorrectly. Anything is possible and I can't stand it any more: any advice on how to do it?

I have passed a url String from java to C code as jstring data type. And my library method needs a char * as url. How can I convert jstring in char * ? p.s. Is there any advantage of using jcharArray in C? (i.e. Passing char [] instead of string in native method).

I prepared following method to convert JIS character string to UTF8 on Android SDK v.1.5. However when I pass JIS character array into JIS the returned string value is same as input. I supposed it should return "undefined" or UTF8 string, Would anybody tell me why this phenomena is occurred?
public String JIS2UNICODE(char[] jis) { String unicode = new String(jis); try { unicode = new String(unicode.getBytes("ISO2022JP"), "ISO2022JP"); } catch (Exception e) { unicode = "undefined"; } return unicode; }

I have phone numbers stored that was transferred from my HTC phone that have a "p" in the dialing sequence to introduce a pause for e.g. a calling card. When this number is used in the X10 it will not recognize the "p" as a pause.
What is the correct character to use?

I'd like to know whether it's possible to have phone numbers converted
into international format when a call is outgoing.
For instance, if a french user (sorry it's the only format i know i
won't make a mistake :-) try to call with the national format :
01.47.12.34.56 then a method will convert it into international format
like this : +33.1.47.12.34.56
I've looked into the doc of the PhoneNumberUtils but i don't know if
there is a method doing what i want.

In Android if I have an edit text and the user entered 123456789012, how could I get the program to insert a dash every 4th character. ie: 1234-5678-9012? I guess you need to say something along the lines of:- a=Characters 1~4, b=Characters 5~8, c=Characters 9-12,

I just moved over from the iphone, one of the things I miss is imessenger. Mainly because I get almost no signal and it can send out most texts through my wifi connection. I want to be able to use my number and I don't want to have to have all my friend install a special app. But I don't mind paying a few dollars for the app or a even a small monthly fee.

I want to have input type for the text boxes that only takes numbers and decimal point. Input type of Number or Decimal, still brings the full keypad and the buttons are small. Input type of Phone does the trick, but not all phones have a comma or a dot to enter the decimal point. What is the best way around?

I am trying to do something that I thought would be simple, yet I still haven't found the right approach. I have a Edit Text field that should only accept unsigned decimal entries. Using android:input Type="number Decimal" in my layout xml file achieves this, however the soft keyboard that is raised with this input Type is the standard keyboard but just uses the alternate view with the number row on top. This is far from ideal for a field that only allows numbers. A much better soft keyboard for numeric entry is the "phone" one. It has all of the numbers and a decimal. Perfect!! Well, except that for the life of me I cannot figure out how to use both the phone keyboard AND allow only numeric entry. I've tried everything I can think of but if I use the phone soft keyboard then the input field also allows things like "(" and any of the other symbols available on that keyboard. Is there any way to get the nice big numeric buttons of the phone keyboard along with only allowing decimal entry?

Alright how does one catch and stop a one decimal point error? The user inputs a single . and that is all; you can not allow that because you will be doing math with that input.if you have this in your xml file:
Code:
<EditText
android:id="@+id/edittext01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:inputType="number|numberDecimal"
android:lines="1" >
</EditText>
and the user types just one decimal and nothing else the program will blow up.I tried the following code but the program blows up at the second IF.At first the two IFs were just one line, they got broken up to see where the problem was As you can see if the length of the user input is only 1 we check to see if it is only one decimal only
The program blows up at the second IF, but errx is a STRING.I used the Log.i to see how far to program went. And the errx is a "."
Code:
if (stop == 0) // checking for one decimal only and nothing else
{
String errx =null;
errx = (edtxt01.getText().toString());
Log.i("ONE DEC:", "START OF IF xxxx: " + errx);
if (edtxt01.length() == 1 ) // *********** 1st if
[code]...

I have a Droid with Android 2.1. I am on a CDMA network. I send messages to some people on a GSM and when we use non-ascii characters, like ± or ¡ or Japanese and such, over sms, the other end gets them as question marks �. I don't know anybody on a CDMA network so I can not test if the problem would be there too. I don't know if it is a problem between the networks or something wrong with my phone or what. Finding information in google has proven unsuccessful. Though I found some text naming it a 'common' problem.

I would like to forward all calls to my number on to the new predefined number automatically. Is it possible to forward incoming call? Probably it is possible for Froyo at least. I found application called Easy Call Forwarding. But many people reckon it dosen't work actually. We can notice forwarded call by onCallForwardingIndicatorChanged() from PhoneStateListener but I have no idea how to set forwarding mode.

My son decided to lock his tablet with a random number he plucked from the universe! one that he can't remember! I'm pretty sure it's a MID here is the link to where I got it from. 8G 7" Android Tablet 4.1 Dual Cam Keyboard Case | Trade Me. I have tried all the different power volume button combos that were suggested on web, also have tried downloading the program to my pc to share info with the tablet, but the information sharing must not be turned on in the tablet, as when the device showed up in my computer it was empty! Where I purchased it from will send me a Getroot, but I have to pay and I'm not sure if this will even work!

I've recently gotten my Andriod phone (on Telus) and have been texting my friends.My phone cuts up text messages to 160 character messages and sends them all to my friends.However, when my friends receive them the 160 character message gets cut in to one 150 and one 10 character message, often splitting up words. So 4 160 character messages are received by their Blackberries (several models) or Samsung (Slyde?) phones as 4 150 character messages and 4 10 character messages.Is there an app that lets you sent 150 or even 140 character messages? Handcent doesn't help with all the split options it has.I tried them all, but it splits at 160 so it doesn't matter.Is there any way to split messages at a lower character count?(All my friends also use Telus (and Kobo which is Telus). Does Telus have a 150 limit? Or is it their phones?I receive messages from them just fine, but that's probably because their phones only send 140 or 150 character messages.)

I am developing application for android phone. Currently I am testing my system in the emulator. In my application, I want to send Unicode character (Amharic language character) via SMS to the other emulator instance. But in the receiver side, the message is not viewed properly. I think the problem is some character encoding related problem. In addition similar problem happens for texts which are queried for the sqlite database. That is when I send a query result via SMS the same problem occurs.
