The two implementations you mention in your post both offer all of the benefits of the CursorLoader except the ability to receive notifications when the underlying content changes. I’ve been looking into this a lot recently and I can confidently tell you that the Android API currently does not provide a means of doing this … Read more
There are two basic methods you can use when making a SyncAdapter: Fill data into an existing ContentProvider. Create your own ContentProvider to store a new kind of data. The former is what’s going on in this example app. They have some website that has a list of contacts, and they want to store those … Read more
I found some explanation here. In summary Content Resolver resolves a URI to a specific Content provider. Content Provider provides an interface to query content. The way to query a content provider is contentResolverInstance.query(URI,…..)
I wasted now lots of hours and now i found a solution which works in all cases without any magic downloading in special threads or something. The following method returns a stream from the content which the user selected and this works with everything in the wild. FileInputStream getSourceStream(Uri u) throws FileNotFoundException { FileInputStream out … Read more
Your android device has many databases, each of which is identified by a unique Content Authority. This is the “domain name” equivalent part in the content:// uri — everything before the first slash. ContentResolver stores data providing a mapping from String contentAuthority to ContentProvider. When you call ContentResolver.query() or update() or what have you, the … Read more
There are two ways to solve this problem. 1. Save bitmap which you received from onActivityResult method You can start camera through intent to capture photo using below code Intent cameraIntent=new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(cameraIntent, CAMERA_REQUEST); After capture photo, you will get bitmap in onActivityResult method if (requestCode == CAMERA_REQUEST) { Bitmap photo = (Bitmap) data.getExtras().get(“data”); } … Read more
I had the same question by the way. And I found a sample here which answers my question. Hope it does the same with you. In short, this is in the DAO object which would be called from Content Provider’s query() method. /** * Select all cheeses. * * @return A {@link Cursor} of all … Read more
The bind value apparently refers to the selectionArgs for the selection, that you insert into query(). If such a selectionArgs value is null, you get this.
According to Dianne Hackborn (Android framework engineer) there is no need to close the database in a content provider. A content provider is created when its hosting process is created, and remains around for as long as the process does, so there is no need to close the database — it will get closed as … Read more
You can also try this: Uri.fromFile(new File(your image path));
