Android :: Defining Data Encoding Of SMS Messages
Aug 24, 2010
I'm working on an application using the SMS apis for android. The receiving end is an embedded unit that only supports 7-bit encoded SMS and the string I'm sending consists only of symbols from this particular alphabet which makes you think that Android is going to send it encoded as 7 bit. But that is not the case.Therefore I'm searching for a way to specify what encoding to use. See below for what my code looks like today. The method gsm7BitPackedToString turns a byte-array to a 7-bit string, i.e. the string only consists of 7-bit compatible characters and is copied from the internal android api. Code...

My input is a InputStream which contains an XML document. Encoding used in XML is unknown and it is defined in the first line of XML document.
From this InputStream, I want to have all document in a String.
To do this, I use a BufferedInputStream to mark the beginning of the file and start reading first line. I read this first line to get encoding and then I use an InputStreamReader to generate a String with the correct encoding.
It seems that it is not the best way to achieve this goal because it produces an OutOfMemory error.
Any idea, how to do it ? code...

I am developing an application which is communicating with the server. Tha application can perform log-in and get different parameters from server.
The application consists of a RESTful client (custom class for making requests), Communication Service (the service which runs in the background) and the main activity.
For now I created multiple broadcast messages and multiple broadcast receivers in the main activity so when the application performs login operation a receiver (loginBroadcastReceiver) in the main activity receives a message and when another parameter is received from the server different message is broadcasted and another receiver handles the message.
This way however the application performance is poor but I am not sure whether it is due to multiple broadcast receivers.
Does anyone know what is the best way to exchange data between service and main activity - is it better to create a single broadcast receiver and retrieve all parameters from message or is it better to initialize multiple broadcast receivers for multiple parameters?

I have started to work with the WebView component of Android Platform, but the API to load data to the component is confusing me, because it includes a parameter with a encoding. In both methods: public void loadData (String data, String mimeType, String encoding); public void loadDataWithBaseURL (String baseUrl, String data, String mimeType, String encoding, String historyUrl); you have to specify an encoding. In both cases, the API documentation says that is is the encodign of the data (data parameter). Well, as know, if you provide data as a String object, the String is internally stored in UTF-16 (unicode). To get a String object from a external source, you need to specify the external source encoding to convert it to UTF-16 and get the String internal representation (String(byte[] data, String encoding)). So, at this moment, when you have an String instance, everything from the original source has been converted to UTF-16. So, why do you need to specify an encoding if you are providing the data as a String object?
I don't know the internal implementation of WebKit, but let's suppose that, WebKit has a method, to render a source, providing as content an InputStream and a default encoding. Well, as I know, when you process a HTML page, you use the default encoding to read the HTML characters, and if you find a <meta> tag specifing a different encoding, from that moment, you have to use the new encoding to decode the characters of the HTML page. But what happens if you supply a HTML page that contains this <meta> tag: <meta HTTP-EQUIV="content-type" CONTENT="text/html; charset=ISO-8859-1"/> using one of the methods specified at the top of this post, how are you going to read ISO-8859-1 encoding from a String that it is in UTF-16 encoding? if the WebKit filtering this <meta> tags, and doesn't taking in account the encoding specified in this tag? Well, all of this is very confusing for me, because I don't understand why the API includes this encoding parameter. I also don't know if the <meta> encoding tags are filtered when the source is provided as a String? Can anyone solve my doubts?

I am facing a problem about encoding.
For example,
I have a message in xml format encoding is "UTF-8".
CODE:.........
Now, this message are supporting multiple language.
Traditional Chinese (big5), Simple Chinese (gb), English (utf-8)
And it will only change the encoding in specific fields.
For example (Traditional Chinese),
CODE:..........
Only "蘋果" and "橙" are using big5, "<product_name>" and "</product_name>" stills in use utf-8.
<price>1.3</price> and <price>1.2</price> are using utf-8.
How do I know which word is using different encoding?

I am using spinners in my application, but when I click the drop down icon the options coverthe entire width of the screen. But I want the options to cover only some part of the screen(ie.. width). By using LayoutParams I am able to change only the spinner icon width but not the options width. I even searched for it,but of no use. Any one help me, I need it very badly.

I've added one new feature to Opencore & Framework to let them support encoding qcelp. But I found that Eclipse cannot figure out this new feature, e.g.
recorder.setOutputFormat(MediaRecorder.OutputFormat.RAW_QCELP);recorder.setAudioEncoder(MediaRecorder.AudioEncoder.QCELP);
Eclipse now does not think RAW_QCELP & QCELP as legal symbols. So, what should I do to update the SDK to pass though this issue? Overwrite its system.img, boot.img or some *.jar packages?

Is there a way to define set values (i.e. 0%, 25%, 50%, 75%, 100%) for the seekbar widget that enables the slider to "snap" to the nearest set value? For example instead of allowing the user to position the slider at an percentage through 0-100, instead the slider can only ever be positioned at one of the five set values? While were on the subject is there an easy solution for positioning the seekbar vertically, I'd rather not hack through the seekbar source code - but I fear I may have to!

I would like to create a widget that can reads its attributes from an XML file onCreate. I've created a Custom Button that extends Button widget. I would like to define its layout and styling in an XML, such that the widget can be reused across different views, with the same styling attributes. The notepad sample code does carry some pointers to this problem, however, it defines a XML layout with the component as View, inside LinearLayout, which is not really what I'm trying to achieve here.

I found a problem with GZIP input stream when wrapping InputStream from HttpURLConnection. When the server response with Transfer- Encoding=chunked, Content-Encoding=gzip and Connection=Keep-Alive. The second post always return -1. After digging into the source code, I found the place that could be a bug: InflaterInputStream.java (line 190 to 192) if (inf.needsInput()) { fill(); } Because InflaterInputStream doesn't need more input, it doesn't try to read the end of chunked encoding (0x)(30 0a 0d) that cause the second post to return with -1 every time.

I am having a specific problem that is preventing me using the android SDK from work. We are using a MS Proxy here that all internet traffic has to go through. The problem seems to be when the emulator is trying to access a site that uses 'Transfer-Encoding: chunked' If I attempt to download www.nds.com (no chunked encoding) into the browser, it works fine. However if I try to go to www.google.com (uses chunked encoding), the browser fails with the message: can't determine content length, and client wants to keep connection opened My feeling (and I'm no expert in this area) is that the underlying code managing the communication through the proxy is not dealing with the null terminator on the chunk encoded response when the connection to the proxy is being kept open? Does anyone have any experience in this area? Is the source to the emulator available so I can try and understand what is going on here?

I'm currently exploring Broadcast Receivers and Broadcast Intent. There are some aspects of the tutorials which are ambiguous to me. To my knowledge this is how the process works. I can broadcast an intent from my application and any receiver on the phone can act on that intent as long as the actions match. I can register a broadcaster receiver on anything that extends Context and when I do so I must provide a filter which will allow the receiver to act on one or more intent actions.The part which confuses me is defining a receiver via the manifest. Must the name of said receiver match a class name? Why should I ever define an intent filter with an action in the project manifest if I always have to provide another intent filter when I register my receiver in code?

Is there already functionality similar to the push registry or wireless messaging API in J2ME implemented in Android? Or at least plans to do so?I have been looking at this issue for a while, because in a corporate environment it is essential to be able to push information out, or trigger actions via SMS or other connections.I have successfully sent an SMS between emulator instances, and successfully received an SMS by using a BroadcastReceiver on another emulator instance. I have also been able to use SmsManager. sendDataMessage to send a data message to a port on another emulator instance, but in this case the BroadcastReceiver is never triggered. This seems to be the closest the API's get to what I'm looking for.

The android docs say that it adds the runnable to the queue and it runs in the UI thread. What does this mean? So, for example, the same thread I use to create my layout is used to run the Runnable? What if I want it as an independent thread that executes while I am creating my layout and defining my activity?

I have been having problem with the carrier, they use to say I have called many numbers and have sent many SMSs I didn't really call or send.
So I was wondering if there is an app which will record all the calls' duration, SMSs sent and 3G/Edge usage.
So I could have a report later and compare it to my phone bill.
