MediaStore: get image data, thumbnail and folder

阅读更多关于 MediaStore: get image data, thumbnail and folder

问题 I have two lists. Let's call them AlbumsList and PicturesList. The first one shows photo album cover (one of the images from it) it's name and number of pictures in it. The second one shows all of the images contained in a chosen album. I've already done it using File class but it works too slow and finds all of the images on device when I need only those from gallery. I've read about MediaStore content provider but have never used it. So I have 2 questions: How to find "photo albums"

Android duplicate provider authority problem

阅读更多关于 Android duplicate provider authority problem

问题 We're trying to publish a pay ad-free version of a casual app that's currently published free with ads. We refactored all package names to com.mycompanyname.appname.pro , the free one on market doesn't have the .pro at the end, basically. We also went into our content provider and changed the authority to the same as the package name. So the "free version" has AUTHORITY = "com.mycompanyname.appname" and the "ad-free pay version has AUTHORITY = "com.mycompanyname.appname.pro" but still we are

问题 I'm trying to batch delete some items in a table. String ids = { "1", "2", "3" }; mContentResolver.delete(uri, MyTables._ID + "=?", ids); However I keep getting this following error java.lang.IllegalArgumentException: Too many bind arguments. 3 arguments were provided but the statement needs 1 arguments. 回答1: The error occurs because you have a single placeholder (?) in your where clause, while you pass three arguments.

Master-detail Using ContentResolver.applyBatch()?

阅读更多关于 Master-detail Using ContentResolver.applyBatch()?

I was wondering if its possible to save master and detail records to a content provider using the android.content.ContentResolver.applyBatch() method in the same operation where subsequent ContentProviderOperation items in the providers parameter depend on the result of previous items. The problem I'm having is that the actual Uri isn't known at the time that the ContentProviderOperation.newInsert(Uri) method is called and the Uri is immutable. What I have come up with is shown below: Master Uri: content://com.foobar.masterdetail/master Detail Uri: content://com.foobar.masterdetail/master/#
