[android-developers] content provider and full text search - best practice?

[dorjeduck]

Hi 

i am in the process of writing my first content provider. The content 
provided includes a fulltext search in the database underlying the 
provider. I was wondering how to design my content provider to hide the 
specifics, should sqlite specific terms like MATCH be given in the *
selection* argument of the ContentResolver or be hidden in one way or the 
other ... Any suggestion how to do this in a nice way would be great.

Thanks

martin

Re: [android-developers] Content Provider in Adobe not working.

[Justin Anderson]

I have run into this before...  Are you using a Samsung device, by chance?

I don't know if your problem is exactly the same as ours, but for us we
were able to get around the problem by temporarily creating a copy of the
PDF in a publicly readable location, and then giving that location instead.

Thanks,

[android-developers] content provider and syncronization

[giugio]

Hello.
I have an application that works with db (sqllte).
I worked with db for a long time, so i know well the commands sql select, 
insert, update, delete, 
I have to create an application that can communicate with a web service 
using php json to synchronize data.
I have a few tables 5/6.
I saw that Android provides tools for synchronization ,many already made
 classes I wondered if i can evaluate the hypothesis of a content provider, 
even if the application does not need to share data with other applications.

for synchronization can be useful work with content providers ? or can be 
an unnecessary waste of time?

these sync api can benefit from the content provider implementation?
Thank you.

[android-developers] Content Provider JUnit Test and Null Pointer Exception

[Dionysus1983]

I am attempting to test the update() method of my custom content
provider. I receive a null pointer exception due to the getContext()
method call within the update() method being null. To alleviate this
issue I have attempted implementing
http://stackoverflow.com/questions/6516441/why-does-androidtestcase-getcontext-getapplicationcontext-return-null
to no avail. My test class looks like the following:

public class AddressContentProviderTest extends
ProviderTestCase2 {
public void testInsert() {
Uri CONTENT_URI = Uri.parse("content://" +
AddressContentProvider.AUTHORITY + "/address");
AddressContentProvider addressContentProvider = new
AddressContentProvider();
ContentValues initialValues = new ContentValues();
boolean isException = false;
Uri returnURI = null;
initialValues.put("country", "USA");
initialValues.put("region", "test");
initialValues.put("city", "Jacksonville");
initialValues.put("state", "FL");
initialValues.put("zip", "32258");
initialValues.put("province", "test");
initialValues.put("geo_location_id", "");

returnURI = addressContentProvider.insert(CONTENT_URI,
initialValues);

assertTrue(returnURI != null);

}

The insert method looks like the following:

@Override
public int update(Uri uri, ContentValues values, String where,
String[] whereArgs) {
SQLiteDatabase db =dbHelper.getWritableDatabase();
int count;

switch (sUriMatcher.match(uri)) {
case ADDRESS:
count = db.update(ADDRESS_TABLE_NAME, values, where, 
whereArgs);
break;
default:
throw new IllegalArgumentException("Unknown URI " + 
uri);
}
getContext().getContentResolver().notifyChange(uri, null);
return count;
}

[android-developers] Content provider with multiple tables

[Andreea Sandu]

I have a question about content providers, or maybe I didn't understand it 
well.
I have an application which uses a content provider. I know the number of 
tables
needed and their names only at run-time (I use Java Reflection), but by 
then the
content provider has already been initialized. 

How can I make a more generic Content Provider, which uses x number of 
tables?

Have the service do a callback to activities during just before starting

[android-developers] content provider locking?

[bob]

 

So, I have a content provider that maintains a list of movies.

Also, there is a service that runs in the background and refreshes the list 
of movies every five minutes.

Is there a good way to ensure no one accesses the content provider's list 
of movies while they are being refreshed?  I don't want an activity to get 
a partial list of movies.  

Thanks.

Re: [android-developers] content provider

[Mark Murphy]

A content provider would have nothing much to do with it.

If you wish to upload files, upload them. If you wish to download
files, download them. There is nothing in the Android SDK that is a
"sync this directory of stuff with this online counterpart". I'm not
even aware of a third-party solution for that, though I seem to recall
there was some work going on for a git client library.

[android-developers] Content Provider using external file storage (text file)

[André Coelho]

I'm trying to code a system for running user studies. I have a webpage
and a webservice on top of a user DB.
My Android app is a client to run the studies on. I'm use the Account
Manager to store user credentials authenticated via the webservice.
The point is to then implement a sync adapter that will send a text
file with study data to my server, via the webservice (using the
credentials).

My problem is that I'm having difficulty with the Content Provider,
I've searched a lot throught the web but I can't seem to find an
example of how to code a Content Provider tied to a file on external
storage. All the examples I find use Content Providers tied to
database tables. Can someone please point me in the right direction or
shed some coding light? (BTW, I have read the Android Developer texts
on Content Providers, also, I'm using Android 2.2).

Any help is appreciated.

Cheers,
André Coelho

Re: [android-developers] Content Provider for Private Database?

[Kostya Vasilyev]

Jake,

ContentProvider isn't just for exporting data.

One useful thing it provides is data change notifications (based on data 
URIs). In practice, it means that ListViews with content 
provider-supplied data refresh automatically, and it's really easy to 
make other UI elements also update automatically by registering data 
change observers.


Another useful thing is that it forces you to map your data into a 
hierarchical URI-based scheme. This, IMO, results in a cleaner 
conceptual model for your data.


Yet another is that you can easily pass data references between 
activities by using a data URI.


On the other hand, with content providers you can't just run a raw sql 
statement whenever you feel like it - all data access is structured, so 
you've got to do some planning first.


Howerver, for debug info, I probably wouldn't bother with a content 
provider or a database at all. Just a text log file, with timestamps, so 
it can be cross-referenced with the logcat (if you can collect that too).


And speaking of debug reports - have you looked at ready-made solutions 
for this? For example, this one is often recommended on this list:

ContentResolver cr = getContentResolver();
ContentValues values = new ContentValues();

values.put(Video.VideoColumns.BUCKET_DISPLAY_NAME,

[android-developers] Content provider persistence

Hi,

I'm writing an application where the user needs to choose a timezone so I'm
using the search capability of Android. For having the time zone as a
recommendation inside the search, I've implemented a Content Provider for
the time zone. The problem is that the content provider remains "alive"
after the selection is made... and I want to destroy it.

How can I do that?

Re: [android-developers] Content Provider and Content Resolver

[Kostya Vasilyev]

A ContentProvider is a generic mechanism for an application to provide 
access to data. This is done by subclassing ContentProvider, 
implementing certain methods, and publishing information in the manifest.


To access data provided by ContentProvider(s), you use ContentResolver. 
There is no need to subclass.


http://developer.android.com/guide/topics/providers/content-providers.html

This mechanism is used in certain Google applications.

Some of those, but not all, are considered to be part of the SDK, and 
can be used by other applications as well:


http://developer.android.com/reference/android/provider/package-summary.html

Some others are internal, and should not be used by other applications.

These internal providers can change at any time: with a new Android 
release, a new version of a Google application, or even when Android is 
customized by a device manufacturer.


These include Calendar and GMail, and perhaps more. It's not a good idea 
to use them in your application.


If you do, and make it work somehow, be aware that your code can break 
at any time.

[android-developers] Content Provider - any file type store..?

[Purushottam Sholapur]

Hi ,

In android it is not directly possible to share files and folders
across different application. The only way is Content Providers.

1. Is there any general (any file type) content store? Today there is
Audio, Video and Image Store.

2. Wanted to write new Content Provider to store Big files, like Video
and Audio. Saw some examples, like
  (
http://developer.android.com/guide/topics/providers/content-providers.html
)

   Uri uri =
getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, values);

   OutputStream outStream =
getContentResolver().openOutputStream(uri);

   sourceBitmap.compress(Bitmap.CompressFormat.JPEG, 50,
outStream);
   outStream.close();

But what functions in Content Provider get called when we do
"getContentResolver().openOutputStream(uri)" ?
Which all function need to overload/implement in cont provider  . .?

3. Is there any example for content provider which stores big files
like video, audio ?
  I want through MediaStore.Image / Video etc , but could not makeout
much.

regards
Purush

That's not supposed to work. AFAIK, the second one will fail to be
used (and I would have expected it to fail to install), since it
attempts to use the same authority (my.authority.com).

I doubt it.

[android-developers] Content Provider Question

[Adam Hammer]

I think I've got to write a content provider for handling a add-on
style architecture for my app.

If I have 2 seperate providers, different .apks and manifests, and
lets say one has the authority

content://my.authority.com/addon1
and the second
content://my.authority.com/addon2

They are both installed and registered. If I do a query on
content://my.authority.com will it come back with both addon1 and
addon2 in the result set?

Basically can you query what tables are available, and not just the
table itself? Will the content resolver sort that out even though it's
not in either actual providers authority?

The content provider described in that thread is undocumented and

None that is documented and supported.

[android-developers] Content Provider URIs Documented?

[the2bears]

Hello,

I found http://groups.google.com/group/android-developers/
browse_thread/thread/eac04c2a99eb681c/4a6c25fe0a956d17?
lnk=gst&q=broadcastreceiver">this link very helpful regarding how
to react to the arrival of an email.

The content: schema seems very sparsely documented, though.  Is there
an equivalent "content://gmail-ls" provider URI for Google Talk/Chat?
Can I have a ContentObserver monitoring chat sessions and then react
based on certain criteria?

Thanks in advance,

Bill

Re: [android-developers] Content Provider for shared preferences. ?

[Olivier Guilyardi]

I think that you want to make a Content Provider:
http://developer.android.com/guide/topics/providers/content-providers.html

With this you can allow other apps to retrieve data from your app. Internally,
you can store this data the way you want, in shared preferences, in a sqlite
database, etc..

[android-developers] content provider failes on insert row

[martinmike2]

Hello, what i cam trying to do is this:

1. Check for db on startup (no problem)
2. If no db, create one (no problem)
3. input some data into the db (problem)
4. save the db (not there yet)


The exception is being thrown when i call cp.insert


I have stepped through the code line by line and the line that throws
the exception, every time, is:

[android-developers] Content provider / ListView - Close the database but leave the cursor open?

[Jawon]

I have a ContentProvider that stores data in a SQLite database. I also
have an app with a ListView that displays data queried from the
ContentProvider. I run a query() on the ContentProvider, then I take
the returned Cursor, make an adaptor, and set it to the ListView, like
so:

dbAdapter = getContentResolver();
deviceList = (ListView)this.findViewById(R.id.deviceList);

Cursor allDevices =
dbAdapter.query(BluetoothContentProvider.CONTENT_URI,

BluetoothContentProvider.ALL_COLUMNS,
null,
null,

BluetoothContentProvider.KEY_ROWID + " ASC");
startManagingCursor(allDevices);
SimpleCursorAdapter cursorAdaptor =
new SimpleCursorAdapter(this, R.layout.device, 
allDevices,
COLUMN_HEADINGS, DISPLAY_FIELDS);
deviceList.setAdapter(cursorAdaptor);


If I close the database inside the query() of the Provider, I get an
"Invalid statement in fillWindow()" error from the returned Cursor,
but I don't want to leave the database permanently open either. What
should I do?

[android-developers] Content provider implementation questions

[Alex Xin]

Hi, All

I'm now trying to implement my own content provider. My original data was
stored on network or local/remote file systems, so I want to provide data
via input stream. I know that client may call ContentResolver.getnputStream
to retrieve the input stream to access data. But I don't know how to
implement content provider in this situation, I searched the Internet but
all the tutorials for content provider are talks about how to expose data
that stored on local database.

Could anyone please help me on this or give me some code snippets to show
how to expose data that stored on file systems using a content provider?

Also could anyone please tell me what happened when client
call ContentResolver.getnputStream? I want to know how to return an input
stream to my client.

Thank you

Alex

[android-developers] Content Provider not updating strings from locale

[swgillan]

Hello.

I have an app that has 3 string arrays. These arrays are coded in both
default english and spanish.

When I update my lists with 2 of the string arrays, they use the
correct language if I change my locale on the phone.

The 3rd array is used as a suggestion list for a search function
(using the startSearch() method). I have a content provider that
updates the list based on the R.array.name, it seems that never seems
to be updated (ie, always shows up in english).

Is there another setting I have to use for it?

I am using it like this inside my class:

public class LocationProvider extends ContentProvider {

@Override
public boolean onCreate(){
Resources resources = getContext().getResources();
LocationList.fill(resources);
return true;

}

The fill method does some other stuff, but I have just echoed out to
logCat to see what is happening:

public void fill(Resources res){
String[] locations = res.getStringArray(R.array.name);
//TEST to see what is in R.array.name
for(int i =0;i<10;i++){
System.out.println(locations[i]);
}
}

In each print statement, it is just the english value that is being
display. Even when I change locale to spanish, run the application,
all my strings are correctly showing spanish except for this list.

Any help or suggestions would be appreciated.

Regards,

Steven Gillan

You are wrong here. If your query is for all rows, it will do the work
to load all rows out of the database and into memory when you access the
first one.

Then don't implement a content provider.

[android-developers] content provider, activity.startManagingCursor and simple dao

[kamiseq]

hi all,
I am writing simple app that will read callLog content provider
transform data and write it to my own table. my app will not show data
directly from calllog content provider.

1. now one problem that I have is I cannot limit how much rows query
will return (by calling activity.managedQuery) but I assume that
Cursor delays access to the db and I can use moveToNext as many times
as desired to get few rows from table and the call will be efficient.
is that good thinking?? OR am I wrong here? I really dont want to
query all rows from table. is there any other way to access calllog??

2. I dont want to implement my own content provider for my app. I will
use rawQuery many times and group data so contentprovider's callbacks
are not enough for me.
more I want my dao to be private to my application so I think there is
no need to bother with conentprovider. and If I got this right I also
dont need to bother with activity.startManagingCursor as long I query
data inside same method call (because I need to deactivate all
intermediate Cursor objects anyway)

thanks for any help

That's really only helpful if the ContentProvider will be used by
something else in the same process, and it is never strictly necessary.

 It's declared in a different class.  So when

Look at the  element in the manifest.

Each ContentProvider declares, for a given Uri, what the MIME type is.
This allows an activity, with only a Uri, to ask Android "hey, please
start an activity that can view one of these...u...things". The
activity creates an Intent with that Uri. Android uses the
ContentProvider to figure out the MIME type for that Uri. Android then
finds an activity that supports the desired action (e.g., ACTION_VIEW)
on that MIME type.

[android-developers] Content Provider General Questions For a Newbie

[Hunk of Hulk]

Hi there,

I am having a hard time understanding content providers.

In the notepad example and others, the content provider never even
declares its CONTENT_URI anywhere inside itself, yet the docs say to
publicly declare this.  It's declared in a different class.  So when
an activity queries a content provider with a CONTENT_URI, how does
Android know which one I want.  I see no link between a content
provider and its CONTENT_URI declared in another class.

I also don't how to think about intents and content providers.  I know
that you don't call an intent on a content provider.  But an activity
queries a content provider without an intent, and an activity has a
mimetype attribute in the manifest that would seem to tie it to a
content provider.

Can someone please help?

I would like to know the exact difference between Content provider and
SQLiteDatabase. If we have to share our data among applications then
we use Content provider, otherwise SQLiteDatabase. Is this is the ONLY
difference, OR using Content Provider has something to do with
performence???
Any input will be highly appreciated.

Thanks

[android-developers] content provider implementation

[vishal bhoj]

Hello Everyone,

Can anyone explain the usage of selection and slectionargs  in content
provider implementation? It states that it filters the rows.


Is it possible to filter based on substrings in the rows?

example db entry has
 _DATA
fun/abc/1
fun/abc/2
fun/abc/3
fun/xyz/1
fun/xyz/2
fun/xyz/3

Can I qwery my content provider to return data column with "abc" entries?

[android-developers] Content Provider Permission

[Isis]

Hi All,
 I want to delete Downloads provider data. And I have added
permission in AndroidManifest.xml,  But it doesn't work, the log gave
me a pid and an uid, I guess the problem is caused by these two ids.If
it's true, what can I do  to solve this problem.

AndroidManifest.xml as follows:
...


...

Java code as follows:
...
ContentResolver resolver = context.getContentResolver();
resolver.delete(DownLoads.URI, null, null);
...

Log as follows:
...
07-07 13:59:10.038: ERROR/ContentProvider(726):
java.lang.SecurityException: Permission Denial: writing
com.android.providers.downloads.DownloadProvider uri 
content://downloads/download
from pid=1714, uid=10085 requires
android.permission.ACCESS_DOWNLOAD_MANAGER
...


Any suggestion or best an example is greatly appreciated.

[android-developers] content provider supports transactions

[ozzoozzo]

Question about ContentProviders being atomic.The spec says  " If the
content provider supports transactions the update will be atomic".

What does this mean ? Who implements the transaction code  ? Is it in
reference to the JDBC drivers?

Thank u

[android-developers] Content Provider and Files

[jphdsn]

Hi,

I want create a Content Provider for JSON files. In that case, where
could I store the files?

First, I thought that I could store the files in an SDCARD, but not
all the devices have or will have an SDCARD.

Second, if I create this files in the app, can I use Content Provider?
And what's the maximum of  kilobits the files could have?

Third, Is there another solution?

Thanks and regard

[android-developers] Content Provider: create/open a file in the overrided "openFile" function

[polo777]

Hello Everyone,

I am trying to override the openFile function of a contentProvider so
that I can use the URI in the loadURL function. The following code is
really spread on the forum but nobody seems to meet any problems on
this line File file = new File(...).
As far as I am concerned, I got a FileNotFoundException and I really
dont understand why!

If anyone has an idea that would be great.
Thanks in advance
Polo


private static final String file_path = "file:///data/data/
com.android.orange.myApp/files";
private static final String file_name = "HtmlView";

@Override
public ParcelFileDescriptor openFile(Uri uri, String mode)
{
try
{
mDbH.open();
// content that I want to add in my file
Cursor c = mDbH.fetchContent();
String content = c.getString(c.getColumnIndex
(DbAdapter.KEY_WEBVIEW_CONTENT));
c.close();
mDbH.close();
//
File file = new File(file_path,file_name);
FileWriter out;

out = new FileWriter(file);
out.write("  ");
out.close();
}

   catch (FileNotFoundException ex)
{
// Checked for file existance already, so this should
not happen
return null;
}
catch (IOException ex)
{
// read or close failed
return null;
}

int m = ParcelFileDescriptor.MODE_READ_ONLY;

if (mode.equalsIgnoreCase("rw"))
m = ParcelFileDescriptor.MODE_READ_WRITE;

if (file.canRead())
{
ParcelFileDescriptor pfd = 
ParcelFileDescriptor.open(file, m);
}

ParcelFileDescriptor pfd = ParcelFileDescriptor.open(file, m);
return pfd;

}
catch (FileNotFoundException e)
{

}
return null;
}

[android-developers] Content Provider and notifying changes

[wonderoid]

Let's say i update a certain note in a database and it has a uri like
the following: ".../notes/2". Now when i notify a change in this uri
using ContentResolver.notifyChange(uri);  is it only cursors
having a single item
" ../notes/2" that will be notified? If i have another cursor that
holds a query for all the notes in the provider ".../notes", (hence it
includes note 2 too), is this going to receive the notification?
Actually i have tried this and it does not seem to get any
notification, so am i doing something wrong or do i have to explicitly
notify that base uri too? (Using cursor adapters so content observers
exist)
