Please direct me to a description of the techniques that the ContentProvider employs to access data. I am trying to understand how it works as well as what is tunable or even if its meant to be tunable. It the memory management tiered, cached, virtual, flat? Is it file based, shmem based, stream based? Can there be a combination thereof?
Any information, suggestions, or references are welcome. The android fundamentals page says: "The data can be stored in the file system, in an SQLite database, or in any other manner that makes sense;" but the android ContenProvider page barely skins the onion.

View 1 Replies View RelatedI am currently in the process of creating an application that records current location of a mobile device in intervals, displaying the route as a coloured line on the device in real-time. At the same time the application is storing the longitude and latitude in a SQLite database as I want the user to be able to bring up that specific route again.The route has a primary key and each waypoint is linked to that route by a foreign key. What would be the easiest way to display the saved route on the map?

I've been playing around with some of them basically just looking @ command syntax for the different programs. Some of them seem promising, and some of them look like they can make ur eris into a stylish paperweight. One app i actviated was $ Toolbox, the only thing this did was echo back Toolbox! in the termina editor lol. Ive seen posts where ppl used dmesg to find out how the internal memory was partitioned. I'll admit i'm a total linux shell newb, but playing around with it is fun for me.

View 5 Replies View RelatedI need to write a ContentProvider to provide a dynamically generated audio stream to be playable by MediaPlayer. That is MediaPlayer will use ContentResolver.openInputStream() to play it. I have read a lot of discussions about this problem but no one had a solution yet.

View 6 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.
Does somebody knows where the file with the actual stored SharedPreferences is located?
View 1 Replies View RelatedHere is what I am trying to do:
- have a database that contains a word, and the name of an image file associated with that word.
- the words from the database will be displayed in a listview
- when the word is selected, a new activity will start displaying the word and the image in an image view.
Would it be best to store the terms in an array and have the list view populate from this array and then pull from the database onitemclick? Or can the list view be populated with the terms from the database?
Will android be able to display the image if the name of the file is stored in the db?

I have an Android app that saves a text file directly onto the phone, in the app's install directory. I need to allow the user to create a new email, attaching this saved text file. When I start the intent to send the email, everything shows up in Gmail correctly, but the attachment does not get sent. All of my searches on stack overflow seem to only deal with attaching an image file from the SD card. Below is the code that I used. Please let me know if I have done something incorrectly.
File myFile = new File(getFilesDir() + "/" + "someFile.txt");
FileOutputStream stream = null;
if( file != null )
steam = openFileOutput("someFile.txt", Context.MODE_WORLD_READABLE);
stream.write(some_data);
Uri uri = Uri.fromFile(myFile);
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType("text/plain");
sendIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
sendIntent.putExtra(Intent.EXTRA_TEXT, email_text);
sendIntent.putExtra(Intent.EXTRA_STREAM, uri);
file.close();
startActivity(Intent.createChooser(sendIntent, "Email:"));
I've also tried sendIntent.setType("application/octet-stream"); but that didn't make a difference. I'm at a loss for why the file doesn't attach and get sent.
Just purchased album washer from winamp (which grabs album art from grace note), I was wondering where the artwork goes and how can I remove it when desired?
I deleted the winamp database but the artwork is still there.
I have also used the stock HTC app to get album art (from gracenote again) and can't get rid of that artwork
why after getting the artwork it shows on other music apps but not others?
Do different apps look in different data bases?
