CursorLoader for Multiple ContentProviders

阅读更多关于 CursorLoader for Multiple ContentProviders

I need to make a ListAdapter that presents data from multiple ContentProviders. The ContentProviders themselves represent one table each from relational database. I want to use the CursorLoader system to retrieve aggregate data into ListView. Is this possible to do with 1 loader or do I need to use multiple loaders? I'd prefer to use one. I'm not sure how I can have 2 ContentProviders interact with each other beyond doing the join manually in code which doesn't seem like a great option either. rOrlig You will have to write a Custom Loader class. For example: public class FooLoader extends

阅读更多关于 How do I restrict access to my ContentProvider to only my apps?

I want to export a ContentProvider for use by another one of MY apps. How do I prevent other apps from accessing it?

If I use an android:permission attribute, can't 3rd party apps just apply that permission to their app? Well, you can use a signature -level custom permission ( android:protectionLevel="signature" ). Then, the app holding the permission and the app defending itself with the permission have to be signed by

Android Schematic content provider library configuration?

阅读更多关于 Android Schematic content provider library configuration?

问题 Jake Wharton mentioned this library in a recent talk and it looks like a great way to avoid a load of boilerplate so I gave it a go. But without any success. https://github.com/SimonVT/schematic Below is the definition of the content provider with the annotation attached and the manifest provider element. The issue is that Android Studio does not like the provider definition because the content provider class does not extend ContentProvider. Caused by: java.lang.ClassCastException: com.myapp

问题 I am trying to query for the playlists created by "Google Play Music" app but haven't been able to do so. I created a playlist using locally stored content. I used the following code to query: Cursor c = managedQuery(MediaStore.Audio.Playlists.EXTERNAL_CONTENT_URI, new String[] {MediaStore.Audio.Playlists._ID, MediaStore.Audio.Playlists.NAME }, null, null, null); This works fine for Winamp but not for Google Play Music.

问题 So I've just implemented a widget for my app. It gets its data from the database through my ContentProvider . I define my own read/write-permissions in my manifest, state that I use them (doesn't seem to make a difference), and require them in the content provider:  <permission android:name="com.nononsenseapps.notepad.permissions.read" android:description="@string/permission_read_desc" android:label="@string/permission_read_label" android

Android private content provider?

问题 I am developing an application that involves some sensitive user information. I retrieve this information via a private web API. I am trying to determine the best way to get this data into my app. Right now I'm exploring creating a content provider that can do so; my hesitation is in making it secure. I want this data to be usable only by my application. Ideally, no other apps would even know it exists. Do you have any pointers or advice on how to do this effectively and securely? Any info on
