View 3 Replies View RelatedI am trying to inject a long text entry into a SQLite database, in a TEXT field. This text has new lines in it (i.e. it spans multiple paragraphs). I can get the new lines to show up if I do the INSERT manually:
INSERT INTO "LOGENTRY" VALUES(5,40,'PLACE','line1
line2
line4
',1283990533315,'4A','TEXT','',NULL);
but if I have the equivalent text in a CSV file and attempt to .import it into the table, I get an error that it's expecting more columns than exist (as soon as the new line is encountered, the program assumes it's the end of the input and thus it's missing columns). Is this possible? Or is the only way to manually do each INSERT?

View 4 Replies View RelatedI have created a program, with a service - the service is "START_STICKY". So when i close the program (i am using Advanced Task Killer, to kill programs) the service is restarted automatically, but this presents a problem cause i get an error when trying to call ContextWrapper.openOrCreateDatabase(ContextWrapper.java:203) (see stacktrace below).
I have created a class to handle context, which will return my Activity's context if it is not null, or a fake one i created if the activity's context is null - and the activity's context is null so the fake one is used, i suspect this may be the problem, but have no idea.
In my activity i have a constructor which gives a reference of it self to the contexthandling class, but it seems the activity is not instantiated (not before the service is started at least) when the system is restarting my service.
There is of cause no problem when the program is just started normally, the service starts fine then... which is why i am suspecting the fake context, i created it as follows (and it is referenced in the manifest application tag with android:name=FakeContext):

I'am trying to use a large DB file. It's as big as >8MB. I built it using sqlite3 in Mac OS X, inserted UTF-8 encoded strings (for I am using Korean), added android_meta table with ko_KR as locale, as instructed above.
However, When I debug, it keeps showing IOException at
CODE:..............
I suspect it's caused by trying to read a big file. If not, I have no clue why.
I tested the same code using much smaller text file, and it worked fine.
Can anyone help me out on this? I've searched many places, but no place gave me the clear answer, or good solution. Good meaning efficient or easy.
I will try use BufferedInput(Output)Stream, but if the simpler one cannot work, I don't think this will work either.
Can anyone explain the fundamental limits in file input/output in Android, and the right way around it, possibly?

I want to allow a user to
a) Specify a folder/filename on storage for creating an SQLite database.
b) Specify an existing file/folder on storage card for opening as an SQLite Database.
Please direct me to a description of the techniques that the ContentProvider employs to access data. I am trying to understand how it works as well as what is tunable or even if its meant to be tunable. It the memory management tiered, cached, virtual, flat? Is it file based, shmem based, stream based? Can there be a combination thereof?
Any information, suggestions, or references are welcome. The android fundamentals page says: "The data can be stored in the file system, in an SQLite database, or in any other manner that makes sense;" but the android ContenProvider page barely skins the onion.

As an example, if people would write their own Source-to-DX converter for their functional language XYZ, would they be able to implement e. g. full tail calls although the .class file does support tail calls only under certain circumstances?
