Re: [android-beginners] Re: Comparing data retrieved from SQL query
And just as safe method for avoiding NPE, its good practice to do the
following...
if(text.equals(queryString))
//do stuff

You cannot use == for comparing strings. You have to use the equals
method:

I am retrieving data from a SQL query. The data retrieves fine. If I
place the data in a TextView field, I see the text.
When I try to compare it in an IF statement, however, the statement
sees the data as false, even if it should be true.
If I set the variable to a good value (not getting data from the SQL
query) the IF statement works fine.
Example
String queryString = c.getString(c.getColumnIndex(table_query));
if (queryString == text){
// do this
}
I have checked my data. If I query the database for table_query =
'text' I receive results.
This is happening for 5 different fields where a comparison is made,
each with a different variable and if statement.

[android-beginners] Database version is zero on initial install
I have released an app (World Time) with initial database. Now i want to
update the app with a database upgrade.
I have put in the upgrade code in OnUpgrade() and checking for the
newVersion. But it was not being called in my local testing...
So i put in the debug statement to get the database version and it is zero .
Any idea why it is not being versioned ?
Following is the code to copy the database from my Assets folder ...
*
InputStream myInput = myContext.getAssets().open(DB_NAME);
// Path to the just created empty db
String outFileName = DB_PATH + DB_NAME;
//Open the empty db as the output stream
OutputStream myOutput = new FileOutputStream(outFileName);
//transfer bytes from the inputfile to the outputfile
byte[] buffer = new byte[1024];
int length;
while ((length = myInput.read(buffer))0){
myOutput.write(buffer, 0, length);
}
//Close the streams
myOutput.flush();
myOutput.close();
myInput.close();**
*
