Android :: SQLite Statement Produce Result To Indicate Duplicate Entries?
Oct 28, 2009For my application, I am trying to add entries without having a duplicate entry, and if there are a duplicate notify the user and have him try again. Using SQLite, which I know very very little about, I have tried these two ways and want to know which one is better, more efficient or a better way to develop it? First way:
db.execSQL("INSERT INTO " + DatabaseHelper.DATABASE_TABLE +
"(LATITUDE, LONGITUDE, RATING) SELECT " + latitude + ", " + longitude + ", " + rating +
" WHERE NOT EXISTS (SELECT 1 FROM " + DatabaseHelper.DATABASE_TABLE +
" WHERE LATITUDE = " + latitude + " AND LONGITUDE = " + longitude + ")");
Second way:
long id = -1;
try { id = db.compileStatement(
"SELECT COUNT(*) FROM " + DatabaseHelper.DATABASE_TABLE
+ " WHERE LATITUDE = " + latitude
+ " AND LONGITUDE = " + longitude)
.simpleQueryForLong();
} catch (NullPointerException e) { return -1;
} return id;
The first way, either inserts or ignores the values, I check by doing so, storing the row-count of the rows into a variable before the call, call that function, and then check its results. If the results is not higher than it was before the call, the insert was made ignored, prompt the user with the 'values exist' message. (Very sloppy, I know but desperate times calls for desperate measures). The second way, returns the actual count of rows that match the numbers I want to store, if the number returned greater than 1, prompt the user with the 'values exist' message. I have been going back and forth, trying different ways but I do not know how to set up SQLite to have UNIQUE pairs, which I was told would be the easiest.

It doesn't seem to be downloads or rating.

Cannot Cast From View To ListView
Mar 23, 2011Ok so I looked around and didn't see much on this but I'm getting this problem with my code
Code:
public class ListView extends Activity {
String [] test=new String[100];
ListView list;
[Code]...
The problem is this line right here
list=(ListView)findViewById(R.id.listView1);
which gives me a Cannot cast from View to ListView and I checked the xml file and it is a ListView so I don't know what the deal is.
Android :: If Statement Not Validating?
Feb 16, 2010I have a strange issue. I am new to java/android but come from a programming background maybe I am just missing or doing something stupid with syntax here. I have a string variable called reportlength
String reportlength;
I then go: reportlength = intent.getExtras().getString("ReportLengt");
Now in my debug console for the variable reportlength it has it set as "d" (that is the correct value it should have)
At this point I have my if statement:

Jan 26, 2010How can I enable assert statement on Android? I have referred to a url: http://android.git.kernel.org/?p=platform/dalvik.git;a=blob_plain;f=d... and done what it said: adb shell setprop dalvik.vm.enableassertions all but nothing happen! The test code is: Log.v("assert 1","1"); assert false; Log.v("assert 2","2"); No matter what I did, "assert 2" will be printed, which means "assert false" does nothing! What should I do? BTW, I use eclipse as IDE.

Jul 23, 2010I'm developing an application that tracks the user's current position and stores it into a SQLite database. Everything works fine, but now I have the problem when querying the database for a track with more than 1000 records it takes nearly 1.5 minutes. On my Desktop it just takes 1 second. I know it's a query with many subselects but I wasn't able to get the right result another way. In my opinion this belongs to the aggregate functions like avg() and sum().

Android :: Using COLLATE In SQLite - Locales Is Ignored In LIKE Statement
Aug 13, 2010When creating my SQLite database in Android I set the database locale - db.setLocale(new Locale("cz_CZ")). This is a Czech locale. A SELECT statement works and takes the locale into account, for example:
SELECT * from table WHERE name='sctzy' COLLATE LOCALIZED
But using LIKE will fail: SELECT * from table WHERE name LIKE '%sctzy%' COLLATE LOCALIZED
BTW. There is no java.text.Normalized class in Android. I thought I could make a second column with a normalized text, stripped of special characters, which would be used for searching - but I am missing a class or way how to normalize the String.
Android :: IF Statement For Intent Started Activity

But obviously that isn't legal so how could I structure an expression to check from what class an intent was started.

View 1 Replies View RelatedAndroid :: Anyone Have A Statement From Google Saying NOT To Use Task Managers?
Aug 1, 2010Does anyone have a statement released from Google or someone within Google telling the consumers to avoid Task Managers on Android devices.I went into VZW, trying to get an additional battery (usually if u complain they send u an additional battery) because I'm getting 5-7 hours out of my battery even when I'm careful and try to stretch my battery. So the women asked questions, do u use Wifi...NEVER, don't even turn it on. Brightness? It's 1/8th of the way on to full brightness, Task manager?No Google said not to use one..So she wouldn't send me a battery because she said that its because I don't use a task manager.I was telling her Google had advised us not to and she said, that's false that Google has approved them to put task managers on people's phones who are having battery problems.(I don't believe that)I looked around Google and could only find it from joe-shomes but couldn't find a statement from Google. Can anyone provide a statement from Google that advises us not to use task managers?
