I have valid JPG files and now I want to load them into a layout containing an ImageView. I have code to findViewId(R.id.myimage). I followed some sample code using File but it did not work. The file is stored at /data/data/com.myapp/files/someimage.jpg.
What is the easiest and efficient way to load and display?

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. The most recent one was in January 2010: http://groups.google.com/group/android-developers/browse_thread/threa.
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.

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've got the URL of a .png image, that needs to be downloaded and set as a source of an ImageView. I'm a beginner so far, so there are a few things I don't understand:
1) Where do I store the file?
2) How do I set it to the ImageView in java code?
3) How to correctly override the AsyncTask methods?
Like the title. I have a small drawable file, but the ImageView is much larger than it. How I can fill it without left any extra space?

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?
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.
Suppose i have an application "MyApp" which has a button and when clicked it should start another application say"App2" but this "App2" should not be installed on the phone it should dynamically be executed.how do i do this in android.it will be helpful if u can explain with some sample code.

I'm now trying to implement my own content provider. My original data was stored on network or local/remote file systems, so I want to provide data via input stream. I know that client may call ContentResolver.getnputStream to retrieve the input stream to access data. But I don't know how to implement content provider in this situation, I searched the Internet but all the tutorials for content provider are talks about how to expose data that stored on local database. how to expose data that stored on file systems using a content provider? what happened when client call ContentResolver.getnputStream? I want to know how to return an input stream to my client.
