I have a binary file which contains image. I have to jump on different locations in file to read the image file. So far I am using mark and reset methods but these are not helping me as I want. And I am using Input Stream to read the file.

View 4 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

Any widget that will display a moving google map with my current location centered? There are a couple apps I've found that are close, they just don't update in realtime. The reason I ask is because I have my 7" galaxy tab mounted in my truck. I use a program called torque to add gauge widgets (coolant temp,boost pressure, rpm,etc) to my home screen and would like to have a moving map display as well. I understand this would be a battery hog,but the tablet is always plugged in.

View 2 Replies View RelatedI am currently making an app which works with images. I need to implement functionality where the user picks a file stored on the SD card. Once they pick the picture (using the Android gallery), the the file-location of the image will be sent to another Activity, where other work will be done upon it. I have seen similar posts here on SD, but none to answer my question specifically. Basically this is the code I am doing when the user clicks the "Load a Picture" button:
// Create a new Intent to open the picture selector:
Intent loadPicture = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
// To start it, run the startActivityForResult() method:
startActivityForResult(loadPicture, SELECT_IMAGE);
From that code, I then have a onActivityResult() method to listen to the call-back:
// If the user tried to select an image: if(requestCode == SELECT_IMAGE) {
// Check if the user actually selected an image: if(resultCode == Activity.RESULT_OK) {
// This gets the URI of the image the user selected: Uri selectedImage = data.getData();
// Create a new Intent to send to the next Activity:
Intent i = new Intent(currentActivty.this, nextActivity.class);
// - Problem Area -
// I would like to send the filename to the Intent object, and send it over.
// However, the selectedImage.toString() method will return a
// "content://" string instead of a file location. How do I get a file
// location from that URI object? i.putExtra("PICTURE_LOCATION", selectedImage.toString());
// Start the activity outlined with the Intent above: startActivity(i);
As the code above states, the uri.toString() will return a content:// string instead of the file location of the selected picture. How do I obtain the file location?
Another possible solution is to send over the content:// string and convert that into a Bitmap (which is what happens in the next Activity). However, I don't know how to do that.
I want to move some files from sdcard to /data/data/myapp/files folder, I can use OpenInputFile and OpenOutputFile and write to it, then delete the original one. But it is slow, so, I tried to use oldFile.Rename(newFile), but it always return false. Any idea? The reason I am doing this is to hide some files from my sdcard, so, nobody can see them.

Where is the best place to put this collection of text files? I am guessing "Assets", but am unsure.
I realize this isn't exactly a programming question. However I seem unable to discover this information elsewhere, so thanks if anyone can answer this. I'm on a Samsung Moment running Android 1.5.
Is there an official support forum for this type of question, or a preferred forum along the lines of ubuntuforums.org?
I've been looking through the filesystem of android, and for the life of me cannot find the files that make up the settings menu in android. It's been a long while since I've attempted modifying anything myself.
