[android-developers] Database access error causes force close
I'm trying to use an SQLite table with Android (and for almost the first
time, period, but I familiarized myself with it using SQLite3 /
tclsh8.4), and I've run into a bit of a problem where I can't seem to
spot the error.
Here is the code where it's failing and force closing:
--- CUT HERE ---
// global - before start of DataBaseHelper class:
private static final String TABLE_GRAINBRANDS = grainbrands;
// much later in DataBaseHelper
ListString grainBrandsList = new ArrayListString();
String selectQuery = SELECT * FROM + TABLE_GRAINBRANDS;
String brand;
SQLiteDatabase db = this.getWritableDatabase();
Cursor c = db.rawQuery(selectQuery, null); // This is the line (75)
// that logcat says causes the force close
--- CUT HERE ---
Surrounding logcat code:
--- CUT HERE ---
I/ActivityManager(15152): Start proc com.jdgapps.andgtbrew2 for activity
com.jdgapps.andgtbrew2/.AndGTbrew2: pid=28296 uid=10327
gids={1015, 1028}
I/ActivityManager(15152): Displayed com.jdgapps.andgtbrew2/.AndGTbrew2: +3s183ms
E/AndroidRuntime(28296):
at
com.jdgapps.andgtbrew2.DataBaseHelper.getGrainBrands(DataBaseHelper.java:175)
E/AndroidRuntime(28296): at
com.jdgapps.andgtbrew2.AndGTbrew2$1.onClick(AndGTbrew2.java:92)
W/ActivityManager(15152): Force finishing activity
com.jdgapps.andgtbrew2/.AndGTbrew2
W/ActivityManager(15152): Activity pause timeout for
ActivityRecord{4280e468 com.jdgapps.andgtbrew2/.AndGTbrew2}
I/ActivityManager(15152): Process com.jdgapps.andgtbrew2 (pid 28296) has died.
--- CUT HERE ---
Unfortunately, this error message doesn't tell me much, and while looking
between tutorials and my code here, I can't see what's wrong with it.
I tried to check in /data/data/com.jdgapps.andgtbrew2/ to see if gtbrew2.db
was there, but /data was empty, so I gather it's hidden. Good security,
normally, but a PITA right now.
Logcat does not show any of the errors that would be generated if the
dabase copy (from assets to the above) failed, so it should be there.
Does anyone see anything that I might have missed?
Thanks,

Re: [android-developers] Database access error causes force close
You could try putting a try/catch block around the offending statement to
catch a generic exception, maybe finding out exactly what exception pops up
might give you a clue?

I tried that. The catch statement, which should have logged the error, became the new source of the force close. And logcat did not give ANY additional data. :-( I also tried deleting the database and re-creating it. It STILL shows up as much smaller than the copy in assets, but I'm still assuming Android quietly does some kind of compression on it.

Re: [android-developers] Database access error causes force close
Put a breakpoint in the catch clause and when it gets there examine the exception - that's how I recently figured out a similiarly puzzling force close.

Honestly, I don't even know how to do that. I've never run into a situation like this, where logcat says, something happened...and it was here. I've always gotten more useful information either from it, or Eclipse warnings. The most frustrating thing about this stuff is that I'm trying to (hopefully) use this app to make enough money to pay for advertising so the games I'm working on (using AndEngine) will have a chance of making money to either directly make me enough money to get out from under Social (IN)Security Disability, which was forced on me by cancer #1, or to make money to add to my investing, which ultimately the same goal. The ironic part is, I can't afford to pay for advertising for the app I hope to make money to pay for advertising so my games can have a chance So when you combine that with this kind of stuff, where I'm completely at a loss, it makes for a really bad week.
