Sprint HTC Hero :: PDF Viewer Unable To Open File

Jan 13, 2010

All of the tickets are electronic tickets (pdf) saved in my gmail, and I thought I would be able to open up the files and just let them scan my phone. Yet when I tried to open the file, it pulled up the PDF viewer app and then told me it wasn't able to open it. Why is this? I also just tried saving the attachment to my sd card from the gmail app and open it from there, but I couldn't figure out how to save an attachment from an email to my phone. Any help here would be great.

Android :: Open Helper To Open Database And Get A Cursor To Pass To CursorAdapter

Jul 1, 2010

I have a ListActivity that uses a CursorAdapter to fill the rows in the view. I wrote a database helper class that gives me back results for common queries I make for my app, and it uses an SQLiteOpenHelper implementation I wrote to open the database. I use the open helper to open the database and get a cursor to pass to my CursorAdapter.

Here's a code snippet:

CODE:...................

The problem I'm having, that I didn't have before I implemented the open helper (before I just opened the database directly without a helper), is when I click on an item, which takes me to another activity, and then go back to this activity. When it initializes everything is fine, and my list is populated fine, but when I go back from the activity that follows, the list is empty and in the LogCat I see "Invalid statement in fillWindow()".

It appears from a few post I've seen that the reason is, when I requery the cursor, the database is closed. But I'm not closing it! I'm scratching my head on this one.

Android :: How To Use SQLite Database? (Create / Open)

Apr 18, 2010

I am trying to use

SQLiteDatabase.openDatabase( "/data/data/edwin11.myapp/databases/myapp.db", null, (SQLiteDatabase.CREATE_IF_NECESSARY | SQLiteDatabase.NO_LOCALIZED_COLLATORS));

To create/open a database instead of making use of the SQLiteOpenHelper (because I want to pass in the flag SQLiteDatabase.NO_LOCALIZED_COLLATORS. However, I am getting this exception for that line of code:

04-18 09:50:03.585: ERROR/Database(3471): sqlite3_open_v2("/data/data/edwin11.myapp/databases/myapp.db", &handle, 6, NULL) failed

04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at android.database.sqlite.SQLiteDatabase.openDatabase(SQLiteDatabase.java:638)...

Doing some testing just before that line of code (using File.isExists) shows that the file /data/data/edwin11.myapp/databases/myapp.db does not exist. Would that be the cause of the error? (Or am I just using SQLiteDatabase.openDatabase the wrong way?) Would it help if I create the file beforehand? (Shouldn't that be taken care of by the SQLiteDatabase.CREATE_IF_NECESSARY flag that I passed in?) If creating the file manually is the way to go, is it just an empty file, or do I have to write something to it?

Android :: Cannot Open Database In Service Layer Class

Sep 15, 2010

When I create a instance of the SQLiteOpenHelper, I always need a "Context" to be passed as its constructor's argument. To use this "Context", in my service layer class, I extends Activity class, though I do not display this activity on the screen because it is my service layer. I always get NullPointer exception when I open the SQLiteOpenHelper in my service layer class, Is it because my service layer class extends the Activity class but I did not show this activity on mobile screen? (That's there is no intent to my service layer class), if it is so, how to get rid of it if I wanna open a SQLiteOpenHelper in my service layer class which do not need to extends Activity, but need a Context object to pass to SQLiteOpenHelper?

Android :: Unable To Open Files

May 13, 2009

No matter what I do I am unable to open a file, either in my app's data directory or on the sdcard and also in a folder on the sdcard. To test I placed a test.txt file in all three directories.When I do listfiles, I get the correct list of files set in an array. I've even tried getting the list and filtering out a specific file and try opening it that way and just trying the first item in the array. Is there some security that may be set that is making it so I cant open files? This is not the emulator, it is on a device.

Android :: Populate Database From CSV File?

May 22, 2010

Is it possible to take a csv file stored in the res/raw resource directory and use it to populate a table in the sqlite3 database? My thought was that, if there was a way to do a bulk import for the entire file into the table then that would be cleaner and faster than iterating over each line in the file and executing individual insert statements...

but I'm having trouble applying those statements in my Android application. My first thought was to try something like the following...but no luck:

db.execSQL("CREATE TABLE " + TABLE_NAME + "(id INTEGER PRIMARY KEY, name TEXT)");
db.execSQL(".mode csv");
db.execSQL(".import res/raw/MyFile.csv " + TABLE_NAME);...............

CursorWrapperInner - Unable To Close Database?

Feb 11, 2010

My application has a ContentProvider that handles the direct SQLiteDatabase access. The activities that query the ContentProvider are returned a Cursor. Even though the activities close the cursor, the application is throwing an IllegalStateException when the ContentProvider exits (or possibly when garbage collection is done) because the activities are not closing the SQLiteDatabase.

The Activity has no direct way to close database. The Cursor returned is an android.content.ContentResolver$CursorWrapperInner type. This type encapsulates the actual SQLiteCursor returned from the ContentProvider.

If the returned Cursor could be cast into its original SQLiteCursor, the SQLiteDatabase used by the Cursor would be accessible and could be closed by the Activity. Unfortunately, the CursorWrapperInner cannot be cast.

Sequence of Events:

1) Activity uses ContentResolver to run a query through a ContentProvider.

2) Content Provider receives the query request through a call to its query() method.

3) Content Provider opens a SQLiteDatabase, performs the query and obtains a SQLiteCursor.

4) Content Provider exits the query() method, returning the SQLiteCursor.

5) Activity receives a CursorWrapperInner object from the ContentResolver.query() call.

6) Activity uses the cursor and invokes the Cursor.close() method.At some later time, either the ContentProvider is deleted or garbage collection occurs. (I am not sure which is the trigger to the Exception)

7) An IllegalStateException is thrown because a SQLiteDatabase remains open and is a leak.

* Closing the SQLiteDatabase in the ContentProvider invalidates the Cursor before the Activity has a chance to use.

* Invoking close() on the Cursor, which is suppose to release all resources held by the Cursor, is not closing the SQLiteDatabase.

* The CursorWrapperInner class prevents the Activity from direct access to the SQLiteCursor which could be used to close the database.

What am I missing?The following is a snippet from the LogCat:

Code:
D/dalvikvm( 722): GC freed 3058 objects / 180664 bytes in 143ms
E/Database( 722): Leak found
E/Database( 722): java.lang.IllegalStateException: /data/data/com.lebruns.android.BookManager/databases/BMMasterCatalog.db SQLiteDatabase created and never closed
E/Database( 722): at android.database.sqlite.SQLiteDatabase.<init>(SQLiteDatabase.java:1580)
