I'm developing an android video uploading app and uploading large amounts of video is a problem, I get different type of exception sometimes (host not resolved, pipe broken), I do a multipart POST but I have a feeling if I upload chunk of bytes one at at time that'll increase upload speed as well as solve connection timeout and these type of problems.

I have a function I am using to upload files. How can I get the number of bytes of the file that have been uploaded (transferred)? Can I setup a timer that does this? If so, what variable to I read to get the number of bytes uploaded?
Here is my code:

First off, let me just say that I recently switched over to the Droid from my Palm Pre on Sprint, which was a huge letdown for me. I'm loving my Droid so far and I just rooted it today with Sholes 1.2 ROM. I'm not that impatient to install a 2.1 ROM on my phone, as I already like 2.0.1 enough to keep it stock.I was curious about installing some of the 2.1 apps on it, which is why I ended up installing Sholes 1.2. However, I've noticed that it seems to take quite a bit of my memory compared to stock 2.0.1. In fact, it seems to run slower in general than the stock 2.0.1. Is there any way to improve this, or should I just wait for the 2.1 OTA?

Especially if it is uploading video recordings off my phone. Is there a way to place a speed limit to the data upload rate? Kind of like a bandwidth limiter for Android?

My wifi is old and dodgy and whenever it gets overloaded it crashes, is there any way on android to limit the upload/download speed?

I just ran a speed test on my 4g in york pennsylvania with one bar and i had 342kb/s. i did not realize how fast it really was. even thought the upload speed for some reason drops to like 50 some. my 3g speeds average is around 150 with a similar upload speed. WOW am i too excited or is this incredible for a phone? also my friend at work just texted me and claims his GayPhone4 is faster than mine we shall find out when i get there.

View 3 Replies View RelatedEpic users are all reporting slow speeds on 3G.Our upload speeds seem to be capped at 200KBPS. Can you Galaxy owners check your speeds with speedtest.net app ?
I'm curious if this is just a Sprint issue. Evo on Sprint is much faster ,so its not a network issue.
I have the same problem as described here, but I will supply a few more details. While trying to upload a video in Android, I'm reading it into memory, and if the video is large I get an OutOfMemoryError. Here's my code:
// get bytestream to upload
videoByteArray = getBytesFromFile(cR, fileUriString);
public static byte[] getBytesFromFile(ContentResolver cR, String fileUriString) throws IOException {
Uri tempuri = Uri.parse(fileUriString);
InputStream is = cR.openInputStream(tempuri);
byte[] b3 = readBytes(is);
is.close();
return b3;
}
public static byte[] readBytes(InputStream inputStream) throws IOException {
ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream();
// this is storage overwritten on each iteration with bytes
int bufferSize = 1024;...........................
I am trying to create a NinePatchDrawable programmatically, but there is no documentation on the constructor's argruments (Bitmap bitmap, byte[] chunk, Rect padding, String srcName). Does anyone know what chunk and padding are... and how to specify them?

The Donut VoiceDialer is far from ideal for in-car use because it requires users to confirm their selection by tapping on the screen. My idea is to enhance it so that it can be hands-free from start to finish.I was looking at VoiceDialerActivity.java and the most interesting part is the function onRecognitionSuccess(), which starts at line 383.We could modify it so that if there is more than one item, it reads the items out loud and then does another recognition cycle among those items.

After graduation I got hired as a Java developer for a company in my area (been there for about a little over a month now). I also starting picking up Android development late in my college career since it closely resembles Java syntax and was easy to jump into.My question is, what would be some good Java / Android projects to do and books to read for recent post-graduates in the software development field focusing on Java?

I have a 16mb binary file and I want to read bytes without using any loop. like if i want to read 16 byte i can pass 16 to some method(if there is any) and it give me my desired result... right now i am using loop for reading bytes but my application is so huge i am afraid that it do not get slow.
View 4 Replies View RelatedI have a frame of 22 bytes. The frame is the input stream from an accelerometer via bluetooth. The acceleromter readings are a 16 bit number split over two bytes.
When i try to merge the bytes with buffer[1] + buffer[2], rather than adding the bytes, it just puts the results side by side. so 1+2 = 12.
How to combine these two bytes to obtain the original number. (btw the bytes are sent little endian)

I have been finishing off the port of one of my games to Android, with the last two things being music and sound effects. I have implemented the music system now, using a series of MediaPlayer instances, and that all seems to be working fine (I only need to do limited things with music, just playing, pausing and stopping really). I am now trying to finish of the sound effects, but I am struggling.
1. I am targeting Android 1.6+ and therefore do not have access to the setOnLoadCompleteListener function. What is my best way to wait until all sound effects are loaded? I am thinking my best bet is to load all my sounds, then load a dummy (short, silent) sound, and then sit in a loop attempting to play that sound (and then sleeping for 1ms) until the play returns non zero. Does this sound reasonable? Would it be crazy to do this process for every sound effect I load, as the calling code expects the load function to stall as long as it takes for the load to complete - I am not interested in the sound pool trying to do any async stuff for me, all of my background loading is done in a separate thread, and this thread can stall as long as it likes, as long as it actually loads what I am asking it to.
2. Is there anyway I can find out when a sound effect has finished playing? The games I am porting might have code along the lines of 'play sound effect, wait for it to complete, then fade the screen out and load next context' which on other platforms is easy enough to implement. In OpenAL for example, at the end of each frame I check if the OpenAL state for a given SFX is now stopped, in which case I update the game side sound handle to let it know it's now in the stopped state. But I just can't seem to find a way to achieve the same thing on Android. I am beginning to think my only option would be to (somehow) work out the length of the sample, and then when play is called, set a timer to trigger 100ms after the sample time (100ms to account for any delay in the sound starting), and in the timer function set the game side sfx state to be stopped. Does this sound reasonable? Are there any better ways of handling this?
3. Will a sound pool run out of ids? It seems it have been designed so you have one sound pool per 'level' and after each level you release the pool. This doesn't really fit too well with all my code so I am trying to avoid it. But I notice the documentation states a lot of functions will work even after a sound id is no longer valid (it has stopped for example), the functions won't do anything, but they want break anything. This to me says that id's are never recycled. So are there limits? If so what are the limits?
4. Finally, are there any plans for improving the sound pool system? Ideally I'd like to see it work in a similar way to the other main sound APIs. The reason being I target multiple platforms on the engine side, and have 100% generic game code, so I need to establish a base level interface to the API which will work across the board. This is made very difficult by the SoundPool API being set up to work in a specific way, as opposed to just having reasonable low level functions, and allowing the end user to wrap this up how they see fit. I like the fact there are high level classes around to handle this work of work, and I agree these should remain, but I'd like to see something perhaps lower level exposed, which the SoundPool could wrap around perhaps.
I wrote a simple test driver to test the bluetooth apis. Anyone can verify whether I am using the API correctly?

I am using the AudioRecord class to analize raw pcm bytes as it comes in the mic.
So thats working nicely. Now i need convert the pcm bytes into decibel.
I have a formula that takes sound presure in Pa into db. db = 20 * log10(Pa/ref Pa)
So the question is the bytes i am getting from audiorecorder from the buffer what is it is it amplitude pascal sound pressure or what.
I tried to putting the value into te formula but it comes back with very hight db so i do not think its right
An Android app I'm writing involves quite a lot of downloading of content (think podcatcher/RSS).
I would like to be able to give the user an indication of how many bytes they've downloaded, so they can make the decision whether they want to use Wifi or not.
To this end, I have found a way of counting the number of bytes read by the app, by wrapping an InputStream in a simple CountingInputStream.
However, this does not take into consideration basic things like packet headers and HTTP headers. More importantly, it does not take into consideration any compression that content may be encoded with.
So, how many bytes did my application download over the network? I'm not so interested in the number of bytes uploaded, but if know how, don't be shy.
I have gone down a fairly low level approach as I am feeding the input stream into an XML PullParser. I will also be needing to do a similar exercise with dumping bytes (images in this case) straight onto the SD Card.
I am going to create an application via improving an existing code which has Apache License 2.0. In the license, it is implied that I need to attach "Notice" and "License" files for the previous code while distributing my new application.
Where is the best place to put these files, before publishing the new version on Android Market?
I create data file in android for my application in the app's data directory. The write is successful with no exceptions but file contents are not complete. It truncates at 90112 bytes. Any idea what is going on ? Is there a limit ?

I have a problem.
1 - From a webservice. NET 2008 (vb), I have a method that returns an array of bytes, the byte array is actually a string "Hola Mundo" ("Hello World" in English) compressed with the Class of System.IO.Compression GZipStream.
2 - The method returns the string "Hola Mundo" compressed, and this is what the webservice returns:
CODE:..............
3 - if I do a test from a windows application from Visual Basic. NET to run this method returns me this string and Unzip with another function I have, it brings me the "Hola Mundo" ....
4 - On Android (Eclipse) and I managed to make the request and bring me the previous string ... but do not know how to decompress and show me "Hola Mundo" ...
5 - I have tried several codes from the web, but none work.

I've tried recording video using MediaRecorder API but the file that gets saved each time is of 0 bytes.
I use the MediaRecorder recorder = new MediaRecorder(); ad then recorder.setVideoSource . . .recorder.prepare() to generate the preview and when the user clicks record, i say recorder.start() but the file recorded is of 0 bytes. And after some time, recorder.stop() -on user click that is.
I just wanted to brag a little about my Aria.I have had it for almost two weeks now and I love it! I was a bit worried at first about the battery life.It seemed to deplete quickly.It was barely lasting a whole day. And that was with moderate use. I think a lot of that was due to the lack of signal where I work. It really drains the battery.I noticed the last couple of days the battery life getting better. I checked the battery monitor and it shows that I have been unplugged from the charger for 2 days and still have at least half my batter left.That is with moderate use. I set it so that everything is not always syncing. I think that helps a lot. Anway, I just wanted to share since there seems to be a lot of talk about the poor battery life. So far I've been impressed and happy with my little Aria!
