I am developing a financial app that stores data in a file.I have noticed that text file i/o is pretty slow. If I switch to a binary format, how much faster will it be? 2x? 10x?I could write my own timing tests but I am hoping someone else has already done it.

View 1 Replies View RelatedI'm trying to unbundle a binary file (sound1.ogg) and store it on the sdcard.So it starts out as a raw resource (R.raw.sound1) and should end up as a copy named /sdcard/ mydir/sound1.ogg I wrote a method called something like copyResourceToFile() and did a copy via file descriptors / streams. But the target file just isn't right.If I do a buffered read, the target file ends up being WAY bigger - like 10x bigger.If I just do a byte-by-byte read for the size of the original file, the target file is the right size but is not the same file. Is there a simpler (well, correct/working) way to do this thing?

View 1 Replies View RelatedI bought an android 2.3.6 phone which no one has tried to root( it seems). So I was wondering if I could root it by creating an update.zip file containing the su binary and the superuser apk and then installing it in the recovery mode. Will this work? I have failed with gingerbreak, unlockroot and z4root.

View 1 Replies View RelatedIn my Android app I want to have an input field with autocomplete. The number of items will be about 300000. The best solution seems to be to put the items into a file (on sdcard), one item per line, each line would have the same number of characters so that I can seek to specific line number. If the user enters something in the text field, I would binary search (via RandomAccessFile) the file and show suggestions.I want the autocomplete to be super fast (ideally under 100ms but I guess it's impossible), what optimizations I can do?
Update 1:
I will convert the users input to lowercase english characters (a-z) with spaces. So 'A/b' would be converted to 'a b' and then searched.
Uodate 2:
I now realized I need additional thing - to search for word-starting substrings.
so I'm trying to write in "Update-Binary" in a Zip File .
In The Zip The Update-Binary is Located : META-INF < COM < GOOGLE < ANDROID < (Here)
I'm trying to write and edit some things into the file , which I have tried with NotePad++ and Notepad and WordPad . None will work ... When I go to Flash I have a Error right away since The Update binary is the system to start the Flash it won't work .

I've tried looking around google, xda search tool, have read all pages (3 of them) in Xposed wiki. I've been trying to cheat in a game called Galaxy On Fire 2 HD (I have purchased it), I've found some tutorials how to do that on iOS by modifying some binary files (assetsdatainships.bin and items.bin), on android those files are in game apk, and I cannot modify them without breaking signature.
I found Xposed framework and I think it could be perfect for my purposes. Is there an easy way to replace those asset files by my own? I have very little programming skills though, but I'll try. I've found a short example in wiki, but I don't understand it. I've read wiki tutorial 2 times but still have only vague idea how all this works.
I am using MapView in my application.I ma getting "android.view.inflateException:Binary XML file line #43:Inflating Class<unknown>" Exception while loading the map second time. First Time it shows correctly

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".

View 1 Replies View RelatedWhen the app starts up it shows the activity label property in the title bar. If you set a different title for the activity in onCreate that will show up later. You see the launcher activity title for a while and then the programmatic title replaces it, which is not very nice visually. The icon on the home screen uses the label for the activity. What I'm trying to do is get a label for the icon on the home screen that is different from the activity title bar. I tried setting the intent- filter label, but that didn't appear under the home screen icon. There is a label property for the application, the activity, and the intent-filter. The activity label is shown for the icon and the title and the other label properties are not shown.

Is someArray[index] a faster way to get to a value than someObject.field?
E.g.: if(intArray[i] == 42) {//do stuff}

I will try to test it soon and post the results; just wondering if you all had any thoughts.
I have a problem drawing a background for my OpenGL app on the emulator. It all works well on an actual G1, but i'm worried that if the emulator has a problem, other android phones may have the same problem. On an actual G1 the background is drawn on the background. All other drawing is drawn in front of it. On the emulator, the background is always drawn on the foreground, obsuring any other drawing. Here are two screenshots, where i have my background only occupying half of the screen: From emulato. Code...

One theory is that the 2.1 signal values are different and thus report a difference in signal in the bars and in settings.
