How to store large blobs in an android content provider?

由 无人久伴 提交于 2019-11-27 04:00:58
I have some large files (images and video) which I need to store in a content provider. The android documentation indicates... If you are exposing byte data that's too big to put in the table itself — such as a large bitmap file — the field that exposes the data to clients should actually contain a content: URI string. This is the field that gives clients access to the data file. The record should also have another field, named "_data" that lists the exact file path on the device for that file. This field is not intended to be read by the client, but by the ContentResolver. The client will

问题 I am developing a set of apps that are distinguished only in certain brandings (think different sports teams); however, I am running into a problem where I am using one Library project for all of the specifically branded apps and want to use the same ContentProvider for all of them. When I created the ContentProvider I declared the AUTHORITY as a constant in the class (per the dev example code) and I am using the same authority in every specific app in the manifest files. It looks like I can

can we get chrome browsing history/bookmarks like we get in default browser using READ_HISTORY_BOOKMARKS permission? PS:I Just want to know is it possible? Yes it is very much possible. Use this uri: content://com.android.chrome.browser/bookmarks instead of Browser.BOOKMARKS_URI String[] proj = new String[] { Browser.BookmarkColumns.TITLE,Browser.BookmarkColumns.URL }; Uri uriCustom = Uri.parse("content://com.android.chrome.browser/bookmarks"); String sel = Browser.BookmarkColumns.BOOKMARK + " = 0"; // 0 = history, 1 = bookmark Cursor mCur = getContentResolver().query(uriCustom, proj, sel,

Cursor.getType() for API Level <11

由 那年仲夏 提交于 2019-11-27 03:05:19
问题 I'm querying the CallLog content provider and need to detect the column types. In Honeycomb and newer (API Level 11+) you can get a columns preferred data type by calling the method Cursor.getType(int columnIndex) which returns one of the following types: FIELD_TYPE_NULL (0) FIELD_TYPE_INTEGER (1) FIELD_TYPE_FLOAT (2) FIELD_TYPE_STRING (3) FIELD_TYPE_BLOB (4) How can I accomplish this on pre-Honeycomb <11 devices? I've tried the following: for ( int i = 0; i < cursor.getColumnCount(); i++ ) {

Download image from new Google+ (plus) Photos Application

由 北慕城南 提交于 2019-11-27 02:03:23
问题 Recently Google added the Photos app for Google+ (plus) and it shows up when you launch an Intent to choose an image. However, if I select an image from Google+ Photos and try to use it in my application none of my current logic is able to return a usable URI or URL to actually get an image that I can download and manipulate. I'm currently using the "common" methods to try to manipulate the URI that can be found here on Stack Overflow and elsewhere. I can provide code if needed, but at this

How to restrict content provider data across applications

由 纵然是瞬间 提交于 2019-11-27 01:58:47
How can we ensure that certain applications are not able to access my data stored in content provider where in certain other applications can access that? Basically I need to allow some application of my interest to access my data stored in Content Provider but I do not want all the applications to be able to access that data. How can I achieve this? Thanks. The easiest way is to protect the content provider with a permission you define. Make it a signature a permission so only apps signed with your certificate are allowed to get it.

What is cursor.setNotificationUri() used for?

问题 I did research on how to use ContentProviders and Loaders from this tutorial How I see it: We have an Activity with ListView , SimpleCursorAdapter and CursorLoader . We also implement ContentProvider . In an Activity we can call getContentResolver().insert(URI, contentValues); via a button click. In our implementation of ContentProvider , at the end of insert() method, we call getContentResolver().notifyChange(URI, null); and our CursorLoader will receive message that it should reload data
