Android :: Convert Binary Data (ISO-8859-1) To String?

Oct 6, 2010

I have created an android app. It sends a data message on a port for communicating with the same app on some other phone. While sending the message, i have encoded it into binary data using ISO8859_1 encoding.

byte[] b1=payload.getbytes();

I am able to receive the data message at the receiving end. But the problem is that after receving it in binary format , My app needs to decode the message back to string or human read-able format. But i am not able to do the same.

I have tried to convert it into String using 'toString()' but string contains binary character .

Android :: Convert InputStream To String With Encoding Given In Stream Data?

May 20, 2010

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...

Android : How Can I Convert A String To UTF-8 In Droid?

Jul 1, 2010

I am using a html parser called jsoap, to load and parse html files. The problem is that the webpage I'm scraping is encoded in ISO-8859-1 charset while Android is using UTF-8 encoding(?). This is results in some characters shows up as question marks. So now I guess I should convert the string to UTF-8 format. Now I have found this Class called CharsetEncoder in the Android SDK, which I guess could help me. But I can't figure out how to implement it in practice, so I wonder if could get som help with by a practical example.

Android :: Get User Selection And Convert It To A String

May 5, 2010

I just got a Droid, and after having used it for a while, I felt like I wanted to make a program for it. The program that I am trying to make calculates the actual storage capacity of secondary storage mediums. The user select from a list of units that ranges from KB to YB and the size the entered gets put into a formula depending on the chosen unit.However, there is a bit of a problem with the program.From my testing,I have narrowed it down to the fact that the user's selection is not really being obtained from the spinner.Everything I look up seems to point me to a method quite similar to how it works in J2SE, but it does nothing. How am I actually supposed to get that data?

Android :: Fast Way To Compress Binary Data?

Nov 2, 2010

I have some binary data (pixel values) in a int[] (or a byte[] if you prefer) that I want to write to disk in an Android app. I only want to use a small amount of processing time but want as much compression as I can for this. What are my options?In many cases the array will contain lots of consecutive zeros so something simple and fast like RLE compression would probably work well. I can't see any Android API functions for this though. If I have to loop over the array in Java, this will be very slow as there is no JIT on most Android devices. I could use the NDK but I'd rather avoid this if I can.

Android :: Way To Get Binary Data From External Device To Droid?

Jul 8, 2010

I'm looking for some input on how to go about a problem I have. We have a device that has binary data that it needs to send out (they are mainly just symbols, but in a custom binary format) over ethernet. I need to intercept this data on the phone and display the symbols over google maps. I'm just wondering the best way to go about this, I have a few ideas but am not sure if they are possible or feasable: 1. Is it possible for the phone to connect directly to the device if the device had some sort of server running on it, then poll for new data? If so, what is the protocol needed to be able to direct connect like that? 2. Perhaps modify the device software to send data to the phone(s) in SMS data message format? Im not sure if it is possible for software to "spoof" an SMS to a phone when it is not a phone itself? 3. Have the device software upload all its binary data to a ftp/http server that is sitting out there somewhere, have the phone(s) connect to that server and poll for new data periodically? I'm brand new to android development, basically all I want to do is grab this binary data from the device on my phone and parse/display it over google maps. How do any of those ideas sound, or is there a much easier way I am overlooking?

How To Parse Binary Data Into Structures

May 15, 2014

I primarily do hardware and firmware design, but a new product my company is developing has the need for an Android app and since I have the most Android programming experience (which is extremely limited) that leaves the task to me. I need a little guidance figuring out how to do a few things so that I can get this app up and running. I already have a simple GUI to display some stuff, but what I need is a way to handle data.

I am trying to receive a 148 byte stream of data over a serial connection, parse it into a structure and display certain values from that structure. The data is packed in a struct that is sent from a micro controller and due to that it has a very specific layout (i.e. the first 8 bytes mean this, the next 16 bytes are this... ). In C, I can just declare a struct with those values and use the #pragma pack function to eliminate any extra spacing the compiler would otherwise inject for alignment purposes, receive the data and do a memcpy into the struct to write the data. It's not the safest or cleanest way to do it, but it takes very little time and if you do CRC tests to make sure the data received is valid it works like a charm.

Now to the root of the problem: How do I declare structs in Java? Is there a way to pack them tightly like you can using C? Once I've received the binary data, is there a way to parse it into the structure easily? These are the issues we hardware programmers face when dealing with Java...

Parse Binary Data Received Through Bluetooth

Sep 22, 2011

I have an application that receives data in binary form through bluetooth. I read the data using bluetoothsocket to an byte[]. But i must parse all messages, because they must have an given format and they are in binary.

My solution was to convert byte[] to a string and then split the string and parse all received messages.

An example of the data to parse:
0000000010000001

I should know that the first 8 zeros are the header and 10000001 the real data.

My idea was to create a string that represents -> 0000000010000001 and then split the whole string in one byte and check the value, like:

string1 had 00000000
string2 had 10000001

I know that 8 zeros are the header, therefore string2 has the representation of the data.

Android : How To Convert A String To An Android.net.Uri

Oct 7, 2010

Question:
I have found that java.net.URI has a create(String uri) option but the android.net.uri does not.

More Specific:
I am trying to grab the output of RingtoneManager's RingtonePicker and set it as the default ringtone with SetActualDefaultRingtoneUri;

Intent intent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);
intent.putExtra( RingtoneManager.EXTRA_RINGTONE_TYPE,RingtoneManager.TYPE_RINGTONE);
intent.putExtra( RingtoneManager.EXTRA_RINGTONE_TITLE, "Select Tone For Rainy Days");
startActivityForResult(intent, 0);

RingtoneManager.setActualDefaultRingtoneUrl (this,RingtoneManager.TYPE_RINGTONE,RingtoneManager.EXTRA_RINGTONE_PICKED_URI);

Problem being that ,RingtoneManager.EXTRA_RINGTONE_PICKED_URI returns a string not a uri.There might be a better way than to convert the string to a Uri. I cannot find a reason why java.net.URI can do it and android.net.Uri can't.

Android : How To Convert SDP Data From Byte Into Object?

Mar 18, 2010

I am currently sending and receiving SIP messages across a network. When I want to add SDP data to a SIP message I use the SessionDescription object in jrtp. This object is then added to the SIP message. But when I get a SIP message from the server its SDP is in a byte[] array. So I'm wondering is there anyway to convert the byte[] back into a SessionDescription object so I can use the SessionDescription object's methods to parse the data?

Android : App To Convert Website Into More Readable Data For Phone?

Nov 12, 2010

I am looking into developing an App that will convert a website into more readable data for an android app. I am at university and have an online notice board which can be viewed on the web but if possible I would like to transfer this into an app on android to make it more easy to read on mobile devices.

What I thinking is that the app would go to the website where the notice board is held and read in the html code to display each notice in a list adapter view. Each notice is within its own div so I assume I could use that to split each notice up into its own button on the list adapter view. Is this possible and if so how I can go about doing this. I have tried google for an answer but I have not yet found a solution to this problem.
