I use BufferedInputStream in my code: socket = new Socket(ip, Integer.parseInt(port)); socket.setReceiveBufferSize(64000); output = socket.getOutputStream(); input = new BufferedInputStream(socket.getInputStream(), 64000); I read incoming packets like this: if (input.available() != 0) { System.out.println("Get Packet: " + input.available() + " bytes"); byte[] b = new byte[input.available()]; input.read(b); incParser(b); }

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?
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}

View 3 Replies View RelatedThis may be impossible but is there any way that I can get a smaller buffer size for AudioTrack than what is provided by getMinBufferSize method?
This is how I am instantiating AudioTrack right now: SR = 44100; bufSize = AudioTrack.getMinBufferSize(SR, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT); audioTrack = new AudioTrack(AudioManager.STREAM_MUSIC, SR, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, bufSize, AudioTrack.MODE_STREAM);
With sample rate of 44100, getMinBufferSize always returns 4800. If I try to make the buffer size smaller than 4800 then I get the following error message: E/AudioTrack( 318): Invalid buffer size: minFrameCount 1200, frameCount 600 E/AudioTrack-JNI( 318): Error initializing AudioTrack E/AudioTrack-Java( 318): [ android.media.AudioTrack ] Error code -20 when initializing AudioTrack.

The following works fine on a G1 but gives an error on the Samsung Galaxy. I was hoping cross-platform support would be better than this. See error below.
private final static int RATE = 44100; private final static int CHANNEL_MODE = AudioFormat.CHANNEL_CONFIGURATION_MONO; private final static int ENCODING = AudioFormat.ENCODING_PCM_16BIT; private AudioRecord recorder_; public boolean open() { int bufferSize = 4 * AudioRecord.getMinBufferSize(RATE, CHANNEL_MODE, ENCODING); recorder_ = new AudioRecord(AudioSource.MIC, RATE, CHANNEL_MODE, ENCODING, bufferSize);
last line gives the following on the Samsung Galaxy phone: 11-14 19:04:07.507: ERROR/AndroidRuntime(7617): java.lang.IllegalArgumentException: Invalid audio buffer size.
When I used BufferedInputStream and I specify a buffer size, Dalvik gives me this warning - Default buffer size used in BufferedInputStream constructor. It would be better to be explicit if an 8k buffer is required.
But right now, my buffer size is already at 8k. What am I doing wrong?

View 4 Replies View RelatedI'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?
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'm writing an image file up loader for android for my favorite image gallery software and it uses FTP.
I've started using Apache-Commons Net FTP as my ftp library based on past stack overflow questions. Like so:
FTP Client ftp = new FTP Client();
try{
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);

I'm trying to clean up some rendering issues for a 3D game -- CowPotato (http://www.cyrket.com/package/ com.froogloid.android.cowpotato).
Basically I'm seeing some flickering, like the next frame is getting flushed before everything is drawn. It is definitely the last few items in my display list that seem to flicker -- if I reorder the list, it's always the last part of the list that flickers.
I understand that the GLSurfaceView automatically provides double- buffering -- it certainly appears to be the case looking at the source. So any suggestions as to why I might be seeing flicker? I put counters into the drawing methods to make sure that all the objects are called each frame, they just don't show up on screen all the time.
I am trying to write a streaming application.I have my own decoder and I am playing PCM audio using AudioTrack. At any point in time I want to know how much data is buffered with the device. I want to use this so that if the data with the device go below a level, I want to go into a buffering mode where I will buffer 2-3 seconds of data before continuing playback again. Can someone please tell me how to do this?

View 6 Replies View RelatedIs it possible to generate an EGL Config with an alpha buffer on the G1? When I request a non-zero number of bits for the alpha buffer I can get a R5G5B5A1 or R8G8B8A8 visual, but neither of them renders correctly to the screen. I assume that's because the G1 only supports R5G6B5 visuals. It does surprise me that I can even get those visuals though. It's fairly obvious looking at the 32bpp visual artifacts that the frame buffer is indeed laid out with 32bpp, but display hardware is treating it as 16bpp, resulting in the left and right halves of my scene rendering in alternate scan lines, with distorted colors. So does anyone know if there is any way to get an alpha buffer on the G1? I've tried using FBO's but they don't seem to be implemented either. Or I'm using them incorrectly. If I call glGenFrameBuffersOES on a GL11ExtensionPack reference I get an UnsupportedOperationException. I am getting my GL11ExtensionPack reference by casting the return value from my EGLContext.getGL() call.
View 2 Replies View RelatedSince Google groups doesn't let you add posts to threads more than 60 days old, and I want to leave a solution to the problem I encountered a while back, I'm posting this message with the same title in hopes that anyone running into the problem I had will find this message as well. I was having trouble getting my G1 to render an RGBA_8888 OpenGL context to the screen. Everything was twice the size it should be because the 8888 pixels were being interpreted as two 565 pixels. The colors were obviously wrong as well. I had missed a critical function call. You must configure the Surface that is being used by EGL using the SurfaceHolder method setFormat. The pixel format needs to be TRANSLUCENT, or more specifically you can use RGBA_8888.
View 2 Replies View RelatedHow can I empty the logcat buffer in Android? I use adb logcat from command line and pipe the output to a file, since the DDMS has a very limited buffer. At the moment, when I restart my app (after fixing bugs etc) the logcat buffer has data from the previous launch as well. Even uninstalling the app does not clear the buffer. The only way I've found so far to clear the buffer, is reboot. This is effective, but would like to know if there's an easier way.

So I'm loading images from a web service, but the size of the images are sometimes smaller or bigger than other images and the visualization looks silly when I put them in a ListView in android. I'd like to fix the size of my ImageView so that it only shows a portion of the image if it's larger than a preset amount. I've tried everything I can think of setting the setMaxWidth/setMaxHeight, setting the scale type to centerCrop, using ClipableDrawable wrapping my BitmapDrawable, setting using Drawable.setBounds(). I've tried setting in the XML and programmatically, but neither worked. I'm very surprised setting max width/height didn't do anything. Below is the XML I'm using ImageView definition in my layout file
