what are the different numbers under the "bytes" section of the app when running?
Is the second number how much i have used or is it the first number ?

With the froyo update, there are so many apps running, both in my task killer, but also in the running apps section of the settings menu. Like Skype, and several I don't use and don't want running. Anyway with froyo to stop these from starting up and running all the time?
View 13 Replies View RelatedI'm working on a client-server Android application and trying to figure out how to identify different phones/users to the server unambiguously. My first attempt would be to use the phone number on the SIM card. Although now that I think about it, how common is it these days that your phone number changes when you e.g. change carrier? I guess it depends from country to country etc.Anyway, I've been trying to figure out, since I don't have actual Android phones, how to change the phone number of the emulator phone to simulate different users. Is it possible or should I just think about alternative ways of identification?
View 3 Replies View RelatedI have noticed some glitches with calls dropping and I don't think these instances are connected: 1) Sometimes I cannot dial numbers that are stored in the phone or using the favs widget and that includes returning a call so the number is already listed. If I hit the number it dials for about a second then says call disconnected. BUT if I manually dial the same number after it drops it will dial out fine. I haven't noticed any rhyme or reason for it doing this. It just seems to happen randomly. Maybe it is linked to low signal? It just seems odd that I can always dial the number after if I type it in. 2) When using GPS naviation (Maps) if I get an incoming call - no problem but if I dial out, after a few seconds on the phone the phone will reboot itself.

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 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
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:
CODE:....................
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 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'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'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'm building an android app and I'm currently having trouble retrieving a bitmap from an URL.
Here is the code I'm using :
CODE:..........
Everything works fine when the picture's write but when some bytes are wrong, result gets null. I think it's basically expectable as it's written this in the doc of BitmapFactory.decodeStream :
If the input stream is null, or cannot be used to decode a bitmap, the function returns null. The stream's position will be where ever it was after the encoded data was read.
The problem is, my wrong picture is well interpreted by my web browser and I can do so on iPhone platform.
Is there a way to sort of ignore those wrong pixels? maybe with the option parameter?
I bought iball andi 5li android smart phone a few days back. The configuration of the phone is:
512mb ram
4gb internal
1.2ghz cortex a9 processor
android 4.1.2
Although my device runs almost every app out there (including temple run, subway surfers etc.) but occasionally im facing problems.
Problem occurs after 3-4 days of restarting the phone. When i restart and check the ram usage it says 350 mb (approx) as used and 150mb(approx) as free ram every app runs smoothly but as days pass by gradually the free ram starts decreasing down to 30 mb where all the apps (games and browsers) start crashing with a low memory message. then the conditions get worse after approx 2 hrs free ram is now 0.0 bytes and even the launcher,settings etc crash with a low memory message. The only solution out is to restart the phone.
[used androids before and is quite aware of closing or killing apps but none is working]
Already Tried:
# removing apps from recent list
# stopping apps from Setting>apps>running apps & cached apps as well
# restoring to factory defaults
# used ram freeing apps (no change on ram)
I'm developing an android app that will play mp3 files. However the mp3 files are encrypted on the sd card or sqlite. Either ways, after decryption, i'll have a stream of bytes. How do i play them? MediaPlayer does not take inputstream as parameter, so i cannot consider that.
View 2 Replies View RelatedI have an app which I think could be in the featured section of the Android Market and was wondering the best way to proceed. The application is Scan2PDF Mobile which uses your phone's camera to "scan" documents and make PDF files which can be saved or emailed from the phone. The pages are enhanced and compressed and then made into a multi-page PDF. Think of it as having a scanner, photocopier and fax machine in your pocket/Sicen Scan2PDF Mobile has been on the Adroid market it is proving very popular, getting an average rating of 4.7. It is unlike any other app on the market and in our opinion would be a good candidate for the featured list - so how do we go about it?

View 3 Replies View RelatedI have a custom adapter to display a list of items with section headings. I've looked at Jeff Sharkey's SeparatedListAdapter and CommonsWare's MergeAdapter as examples of how to achieve this, and I now have a solution which works by providing a separate adapter for the content of each section. This creates a big performance problem, though. In my case, there are potentially thousands of items in the list, each with an associated date, and I want to use the date as section heading for all the items with that date. So, without section headings, I'd have a single Cursor which returns the items sorted by date. Nice and easy. With section headings, I'm currently doing this: One Cursor to select all distinct dates in the dataset. For each distinct date, a separate Cursor to return the items matching that date. Pour the dates (section headings) and separate SimpleCursorAdapters for each date's items, into my custom adapter.

View 7 Replies View RelatedSo I've recently released an application on to the Android Market. Whilst it was in the "Just In" section I was seeing decent download numbers, but since then interest seems to have dropped off significantly. I think now people can only find my app through a specific keyword search, which doesn't make me particularly confident about it ever becoming popular.
What can you do when your app has passed the 'Just In' stage but has not reached the 'Featured' stage? The majority of applications seem to be in this middle stage so I think other people must have a similar problem. It seems like the 'Featured' section just makes the popular apps more popular, and makes it really difficult for newer apps to ever catch up with them. Does anyone know if the situation with the Apple App Store is any different?
It seems to be possible to refresh your app and make it appear in the 'Just In' section again if you update it sometime after, but I can't find any real guidelines on this. Is anyone familiar with the specific rules for this, and is repeatedly riding the 'Just In' buzz the only viable strategy for a new app?
I'm adding section headers for my listView, there are few methods on the web. Since I'm using simpleCursorAdapter to manage my listView, I adopted phil bogle's method. http://thebogles.com/blog/2010/02/section-headers-for-android-listviews/
The error occurred at this part of the code:
CODE:.................
This is the LogCat shows how they compare while I scroll up the list:
CODE:..............
The correct output should be:
Sun, 05 Sep 2010
112
120
But when I scroll up, the setViewValue calls 120 first and compare with preDate(show above), it becomes:
Sun, 05 Sep 2010
112
Sun, 05 Sep 2010
120
So how can I make the section headers fixed after creating the headers? Why setViewBinder been called while scrolling?
Had my hero a few months and only just started to play about with it! I am unable to download apps through the market section. Any other way I can do it?
