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 : Working With SQLite Database / Getting Cursor Out Of Bounds Exception

Jun 30, 2009

I am having some trouble working with the SQLite database. I am able to create the database, add to it, and delete from it with no problem by following the Notepad examples, but I am trying to avoid duplicates and therefore want to check to see if an entry exists already.

Below is the code I have for testing to see if a game exists. I get the correct Log message of "No Games" when there are no games, as well as the correct value for column from getColumnIndex which is proven to me by the log printout telling me that column = 1.

The error message that I receive if I don't catch the exception says "Caused by android.database.CursorIndexOutOfBoundsException: Index -1 requested, with a size of 1

Where is Index -1 being requested if my call to getColumnIndex is returning 1? Code...

Android :: Illegal Argument Exception When Trying Run Open GL ES 2.0 Application

Jun 12, 2010

When I add the following line to my GLSurfaceView class I get an IllegalArgumentException from some random place. I don't know where the problem is because it doesn't give a stack trace. set EGLContext Client Version(2); What else do I need to do to get an OpenGL ES 2.0 application to work? I have tested this with a completely empty renderer class (and also put breakpoints on every callback, and none of them get hit, indicating that the error occurs before my renderer even gets involved). Does anyone have a complete working example of how to get started with Android OpenGL ES 2.0 development? [There is also a stackoverflow entry here -> http://stackoverflow.com/questions/3026368/illegalargumentexception-w]

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 :: How To Fix Error Code 5 : Database Is Locked

Oct 15, 2010

I'm creating a Thread and in that thread I open a database connection using the DBHelper, perform an update on a field in my database and close it. I create a separate one in the Thread because if the View is closed the global one for that view is closed, causing my Thread update to throw an error. The thread is in a View, that also has it's own instance of the DBHelper and opens the database onCreate closes it onPause opens it onResume closes it onDestroy The instance in my Thread is throwing this but not all the time :error code 5: database is locked Is there a known practice I should implement so I don't get this error?

Android :: Error Code 5 : Database Is Locked / Way To Fix?

Aug 23, 2009

I have different background threads in my application, one doing periodical database updates, another responsible for doing long searches and so. Obviously some are just reading from database while others are writing as well. Once in a while I get "database is locked" exception. I need to know the safe way of reading/writing from/to database on different threads. As well I've found "isDbLockedByCurrentThread()" and "isDbLockedByOtherThreads()" methods on SQLiteDatabase. Should I use them every time I want to access the database? What if the database is locked? Should I pause the current thread and retry a few milliseconds later?

Android :: AssetManager/InputStream Exception - Doesn't Load The File?

Jul 10, 2010

Doing Android 2.1 development. Can anybody explain to me why the following code generates a IOException and doesn't load the file? This exact code used to work, and as far as I can tell, it should still work. For reference, the Log.d() command correctly lists all files that I expect, and the files are correctly zipped into my .APK file.

CODE:........

Any ideas on why this breaks now? The files I'm trying to read are tiny (couple of bytes) binaries.

Android :: JNI - C++ Code Can Directly Read The App's Sqlite Database

Sep 22, 2010

I'm working on an Android app with a Java component and a C++ component via JNI. The C++ component is used on other platforms. It would make my life considerably easier if the C++ component could query the existing SQLite database (via the SQLite C API), without having to shell calls out to the Java side.
