ContentObserver should call if and only if ContactsContract.Contacts.CONTENT_URI changes

阅读更多关于 ContentObserver should call if and only if ContactsContract.Contacts.CONTENT_URI changes

As my application uses content from android.provider.ContactsContract.Data (API > 11) and ContactsContract.Contacts.CONTENT_URI (API < 11) to populate Contacts . I've tried to registerContentObserver() against these provider. But it calls my ContentObserver even if I tries to Call a person from device as soon as I put the call.

How to show more providers with ACTION_OPEN_DOCUMENT

阅读更多关于 How to show more providers with ACTION_OPEN_DOCUMENT

I want to use the android system dialog provided as part of the Storage Access Framework to open a file. I do this with Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT); intent.addCategory(Intent.CATEGORY_OPENABLE); intent.setType("application/pdf"); startActivityForResult(intent, EDIT_REQUEST); and then handle the returned URI in onActivityResult() . The problem is that, in the resulting menu, I get far less content providers than I expected. Only Google Drive and Downloads (see left screen shot below). Others, like Dropbox, Solid Explorer,... are not show. I suspect the reason is that

阅读更多关于 Own ContentProvider with SQLite and multiple tables

问题 I am reading this tutorial on implementing my own ContentProvide for working with SQLite. Int the ContentProvider.query there are a few thing that puzzles me.

Now if I wanted to query another table, lets say nodo, how would I change the ContentProvider? Should I append the table names somehow in queryBuilder.setTables(String inTables)? What about the CONTENT_TYPE and CONTENT_ITEM_TYPE

阅读更多关于 Listen to android calendar changes. (Sync/Delete/Insert etc..)

问题 I've understand I have to use Content Provider to get all changes, but I also realized starting API14 there is a ready Content Provider for the calendar which I can use to listen to instead of "building" my own custom one. Is there anywhere I can see an example of this ? Can someone please post the core of this listener ? Thanks 回答1: First you need to add this type of receiver to the Manifest: <receiver android:name="your.package.name.CatchChangesReceiver" android:priority="1000" > <intent

Possible to use multiple authorities with FileProvider?

阅读更多关于 Possible to use multiple authorities with FileProvider?

Background I maintain a library whose core functionality involves sharing programmatically-captured screenshots to external email applications.
