Android :: Getting File Size Before Input Stream

Aug 12, 2010

I want to create a progress Bar for an FTP download. The server where I am downloading the file has all of its directories and files hidden. I want to display the progress of the download. Is there any way I can get the file size? Here is my current code:
FTP client = new FTP Client();
FTP client.setListHiddenFiles
FTP client.connect(host Part);
FTP client.login(user Name, password);
FTPclient.setFileType(FTP.BINARY_FILE_TYPE);
Input Stream instream = FTP client.retrieveFileStream(pathExcludingHostIncludingFirstSlash);
int l;
byte[] tmp = new byte[2048];
int update Counter = 0;
int bytes Downloaded = 0;
while ((l = instream.read(tmp)) != -1) {
Foss.write(tmp, 0, l);
bytes Downloaded+=2048;
update Counter++;
if(update Counter==3){
kilobytes Downloaded=(bytes Downloaded / 1024);
publish Progress((String[])null);
update Counter=0}

Is this possible?

Android :: IO Exception While Reading From Input Stream?

Aug 13, 2009

I'm running into a strange problem while reading from an Input Stream on the Android platform. I'm not sure if this is an Android specific issue, or something I'm doing wrong in general. The only thing that is Android specific is this call:
Input Stream is = getResources().openRawResource(R.raw.myfile);
This returns an Input Stream for a file from the Android assets. Anyways, here's where I run into the issue:
bytes[] buffer = new bytes[2];
is.read(buffer);
When the read() executes it throws an IOException. The weird thing is that if I do two sequential single byte reads (or any number of single byte reads), there is no exception. Ie, this works:
byte buffer;
buffer = (byte)buffer.read();
buffer = (byte)buffer.read();
Any idea why two sequential single byte reads work but one call to read both at once throws an exception? The Input Stream seems fine... is.available() returns over a million bytes (as it should).
Stack trace shows these lines just before the Input Stream.read():
java.io.IOException
at android.content.res.AssetManager.readAsset(Native Method)
at android.content.res.AssetManager.access$800(AssetManager.java:36)
at android.content.res.AssetManager$AssetInputStream.read(AssetManager.java:542)
Changing the buffer size to a single byte still throws the error. It looks like the exception is only raised when reading into a byte array.
If I truncate the file to 100,000 bytes (file is: 1,917,408 bytes originally) it works fine. Is there a problem with files over a certain size?

Android :: Chunked Encoding - GZIP Input Stream

Mar 3, 2010

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.

Android :: Parsing Speed / Reading Vs Converting Input Stream To String?

Jul 23, 2009

I'm downloading text data from a web server, and getting an Input Stream. The data will be relatively large and delimited. I want to split this data by the deliminator and store each piece in the DB. Is it faster to read the Input Stream byte by byte to split the data and store each piece in the DB, or would it be faster to convert the Input Stream to a String and use an existing function such as Split?

Android :: Change Internal Buffer Size Of Data Input Stream

Apr 1, 2010

I'm using this kind of code for my TCP/IP connection:

sock = new Socket(host, port);
sock.setKeepAlive(true);
din = new DataInputStream(sock.getInputStream());
dout = new DataOutputStream(sock.getOutputStream());

Then, in separate thread I'm checking din.available() bytes to see if there are some incoming packets to read. The problem is, that if a packet bigger than 2048 bytes arrives, the din.available() returns 2048 anyway. Just like there was a 2048 internal buffer. I can't read those 2048 bytes when I know it's not the full packet my application is waiting for. If I don't read it however - it'll all stuck at 2048 bytes and never receive more. Can I enlarge the buffer size of DataInputStream somehow? Socket receive buffer is 16384 as returned by sock.getReceiveBufferSize() so it's not the socket limiting me to 2048 bytes. If there is no way to increase the DataInputStream buffer size - I guess the only way is to declare my own buffer and read everything from DataInputStream to that buffer?

ftp.connect(host);
Log.i(TAG,"we connected");
if(!ftp.login(user,pass)){
ftp.logout();
//TODO: alert user it didn't happen
return;
}
String reply Status = ftp.get Status();
Log.i(TAG,reply Status);
int reply Code = ftp.triplicate();
if (!FTPReply.isPositiveCompletion(reply Code))
{
ftp.disconnect();
//TODO: alert user it didn't happen
return;}
Log.i(TAG,"we logged in");
ftp.changeWorkingDirectory(path);
ftp.setFileType(ftp.BINARY_FILE_TYPE);
for(int i = 0; i < content Uris.size(); i++){
Log.i(TAG,"uploading new file");
Uri stream = (Uri) content Uris.get(i);
//InputStream in = openFileInput(getRealPathFromURI(stream));
Input Stream in =this.getContentResolver().openInputStream(stream);
BufferedInputStream buffing=null;
buffing=new BufferedInputStream(in);
ftp.setFileType(ftp.BINARY_FILE_TYPE);
boolean Store = ftp.storeFile("test.jpg", buffing);

Android :: Use An Audio File As Input To Speech Recognition?

Nov 13, 2009

Is there a way to use an audio file as input to speech recognition? If not, is this feature expected in the foreseeable future?

A separate question (and this is going to sound ridiculous, but it might actually be okay for a joke app I'm thinking about): Would it be possible to play audio out of an Android handset, while at the same time having a recognizer listen to it via the microphone? (Guess I could just try it.)

Android :: Deleting Files Created With File Output Stream

Jul 20, 2010

I'm developing for the Android platform.

My app creates a temp file with a simple call to:

FileOutputStream fos = openFileOutput("MY_TEMP.TXT",Mode);

It works fine because I can write to it and read it normally.

The problem is that when I exit from the app I want to delete this file. I used:

File f = new File(System.getProperty("user.dir"),"MY_TEMP.TXT");
f.delete()

But it always returns false and the file is not deleted.
I have tried

File f = new File("MY_TEMP.TXT");
f.delete();

And it does not work either.

Android :: Method To Capture Video To File Or Stream From OpenGL App?

Sep 16, 2010

Does anyone knows some convinient method to capture video to file or stream from OpenGL app on Android device? For example, can we capture video from a view, opengl view?

I just found out the following:
1) We can get frames using glReadPixels. (No video on this step?)
2) MediaRecorder can encode video, but how can we provide it our raw source, if possible?
3) Any working ports of ffmpeg(for example) or other encoding libraries? There are some tutorials of portng ffmpeg to use withing NDK. So, having raw frames and working port of ffmeg we can create video? Any issues on this step? Anyone managed to port any encoding library successfully? What components do I need from ffpmeg?

Android :: Is It Efficient To Use Text File Or XML File To Store Static Data

Jul 31, 2009

I have some reference data in a text file (~5MB) that I want to use with might android application.The file is of the format:
1|a|This is line 1a
1|b|This is line 1b
2|a|This is line 2a
2|b|This is line 2b
2|c|This is line 2c

What I want to know is the most efficient way (less memory, fast, size etc.) to use this file within my application.

a.) Should I save the file as a raw resource and open and read the whole file whenever I need a certain line.
b.) Should I convert the file to XML and use XPath to query the file when ever I need to look up a value
<!--sample XML -->
<data>
<line number="1">
<entry name="a">This is line 1 a</entry>
</line>
</data>
c.) Should I just copy & paste the whole file as a static string array in the application and use that.
[EDIT] I will also need to search this file and jump to arbitrary keywords e.g. "line 1a".

Android :: Resize Large Bitmap File To Scaled Output File

Jul 26, 2010

I have a large bitmap (say 3888x2592) in a file. Now, I want to resize that bitmap to 800x533 and save it to another file.I normally would scale the bitmap by calling Bitmap.createBitmap method but it needs a source bitmap as the first argument, which I can't provide because loading the original image into a Bitmap object would of course exceed the memory (see here, for example).Is there a way to read a large image file with 10MP or more and save it to a new image file, resized to a specific new width and height, without getting an OutOfMemory exception?I also tried BitmapFactory.decodeFile(file, options) and setting the Options.outHeight and Options.outWidth values manually to 800 and 533, but it doesn't work that way.

HTC 4G :: Talking On EVO In Car Via AUX Input?

My friend claims that when he plugs his G1 into his car stereo AUX input, he can leave his phone on the dash and just make regular calls w/o using speaker phone. He says that the voice is pretty clear on the other end. Has anyone tried this with their previous phones? More importantly, does anyone know if the mic on the EVO would be sensitive enough to make descent calls via AUX? I know that it would depend on the background noise in the cabin as well, but I just wanna know if it'll work decently in an average car. this would alleviate the need for a bluetooth headset, which i dread using.

Android : Is There A File Picker Widget For Custom File Formats

Oct 27, 2010

I'm writing a bitmap editor. Each document consists of about 3 bitmap layers and documents are, at the moment, saved as a custom file with a .bme extension. These files can be converted to standard jpg/png files by rendering each bitmap on top of one bitmap and saving the latter. I need some way for the user to be able to select .bme files they've created already. Is there anything in Android that can make this easier for me? The only option I can see is to write an activity that creates a list view and write a list adapter that looks for .bme files on disk i.e. a copy of the standard "Media Gallery" app that works for my .bme files. The list adapter will either have to generate a thumbnail preview of the image to show to the user or I'll have to package such a preview in the .bme file when they're created. This is the only option I can think of. I thought I'd ask in case there is more Android friendly way of doing this. For example, can you add custom file support to the "Media Gallery" app?

Obviously the NAS is standalone, so I won't have a PC on (hence no tversity, twonky, orb, playon, etc).

I wish mVideoPlayer did this, i'd be in heaven.

I guess if such an app doesn't exist... is there anything that can play video from a DLNA/uPnP device over both 3g and wifi? Either way, still looking for a solution to streaming video on android heh.
