I am using MediaStore.Images.Media.insertImage(ContentResolver cr, String imagePath, String name, String description) function to insert a newly created image into gallery. System is naming the file by default, but its different than names of pictures taken by original app(Time stamp). Is there easy way to set it up?

View 2 Replies View RelatedAfter I've used a MediaStore.ACTION_IMAGE_CAPTURE intent to take a photo, when I try to retrieve the captured image, I sometimes get an out of memory error as shown below. The odd thing is the huge size of the memory trying to be allocated is always reported as 10,077,696 (x99c600). However, the image file is much smaller, typically around 750,000 bytes.Any suggestions on how to get around this problem? I'm testing this on a Nexus One with firmware version: 2.1-update1 and Build number: ERE27. Code...
View 2 Replies View RelatedI have seen a number of posts from people who had trouble retrieving a full size image from MediaStore.EXTRA_OUTPUT with code...
Should this code work? I mean, should this result in a file containing the picture?
I manage media (images, sound) of my app directly, reading and saving to the SD card. Should I be using the MediaStore instead? I'm not quite sure what the MediaStore is for, and the javadoc is not very helpful. When should an app use the MediaStore? A brief overview of the pros and cons of the MediaStore.
View 2 Replies View RelatedI wonder if anyone knows whether the built in media player uses some kind of caching of mp3 files ID3 tag information, because after I change the tag of a file it doesn't show the updated data. Only after the phone restart, I guess after /sdcard remount, does it show correct tag info.
View 2 Replies View RelatedI'm using Android SDK 1.5 r3. I have source code of Media Provider which i wanted to modify. My intention behind is: add http server files in the data base & Music application can list urls & can play on Media Player. So that i've created new project with package like com.android.Media & copied all the java files & related resource & manifest files in project. But Media Provider is using some internal packages like android.media.MediaScanner, android.media.IMediaScannerListener, android.media.IMediaScannerService, android.os.FileUtils, android.os.SystemProperties, etc. I guess these packages are not available in SDK. So my question is how do I build the Media Provider source code & do my task ? What is the alternate development method is available in Android for this kind of task? Is is possible to create SDK from Android source code which contains above mentioned packages ? and I can use this SDK in windows to build Media Provider application.

I'm writing a simple budget app for myself, and I'm having trouble figuring out how to write to internal storage. I don't seem to be writing to the file properly and I can't find any more in depth examples than the Data Storage article on developer.android.com. Basically, I'm trying to write a test float to the MyBalance file, then read it into balance. In my actual code I use try/catch statements around the file in/out operations but I skipped them to make the code more readable.
float test = 55; float balance; byte[] buffer = null;
FileOutputStream fos = openFileOutput( "MyBalance", Context.MODE_PRIVATE );
fos.write(Float.floatToRawIntBits(balance));
fis.read(buffer); //null pointer
ByteBuffer b = ByteBuffer.wrap(buffer);
balance=b.getFloat();
That's the gist of it, anyone see what I'm doing wrong? I went ahead and converted to/from String but I still don't think the file is being created. I have an if statement that reads from it if it exists in onResume() and it isn't being run. Lemme post some of my code. Here's how I'm writing the file, (setbal is an EditText and balanceview is a TextView):
balance = Float.valueOf(setbal.getText().toString());
balanceview.setText(setbal.getText());
balstring = String.valueOf(balance);
for (int i = 0; i < balstring.length(); ++i)
try { fos.write((byte)balstring.charAt(i));
} catch (IOException e) { e.printStackTrace();
}
I check if the file exists in onResume() like so:
File file = new File("data/data/com.v1nsai.mibudget/balance.txt");
Is that where an internal file for that context would be stored?

View 1 Replies View RelatedI have an image on a private file.
I read the file, create the drawable, and assign it to an ImageView.
The ImageView has WRAP_CONTENT so the size is automatic.
On 320x480 screens, the image looks good
But on screens with more resolution and high density 480x800 or 480x854 (N1, droid) , when the image is for example 150x150, I see the image as 100x100.
Of course it has something to do with the density but not sure how should I resolve this.
This is my code...
if I then inspect the size of the icon, android thinks the size is 100x100, when really is 150x150.
Looks like its reducing the image by the density.
Can anybody explain this and how to avoid this.

View 1 Replies View RelatedI searched the Incredible forums and sub forums and could not find an answer to this question, though I am sure it has been asked: If I want to go from my stock 2 GB card to a new card, and I want to preserve data AND have all apps still be able to read whatever data they were reading off the card, do I just transfer the files from one card to the other? I bet the only thing I need to make sure of is that new card is formatted with the same file system as the original card, right? I know copying data from one card to the other will preserve data, but I want to make sure I have no problems with apps, either, after inserting the newer card.

. index x y orientation
vertex 1 0 0 0
vertex 2 5 0 0.5
vertex 3 10 2 0.3
so i need to do in java something like fscanf does in c (fscanf scans the text file for known formatted data... example, in the file i written i know each line has a string float float float and i need to put them into a specific data structure that can be a list of elements "vertex"
next, when i have all the data, draw a simple image rappresenting the data..
my questions are...
there is a function like fscanf?
and then.. what's better for drawing the 2d map? i have tu use Opengl? At the end i have to draw the image pixel by pixel.. i hope there is something easier then openGL
