[android-beginners] List content observers
Hi there I'm building an app that uses content observers. My problem is, that I tend to register my content observers multiple times. This causes my application to log events several times. How do I find out, if my content observer is already registered? - Frederik -- You received this message because you are subscribed to the Google Groups "Android Beginners" group. NEW!

Hi Richard Thanks for answering. Sorry for the double post.

[android-beginners] Setup SQLite db at install time
Hi group I am new to developing programs to the Android framework. I've read the sample exercises (http://developer.android.com/guide/ tutorials/notepad/notepad-ex1.html) but have a question regarding their database creating. All database creation happens in the function ["onCreate()" - NotesDbAdapter.java ln 67]. As I read the code, the create statement is run without checking that the DB exists. What if the db exists already? How ofthe is the function run? ... It doest override a method, but the class does not extend any class and thus does not inherint any functions to override? I've seen some work-arounds on the internet: To include a "IF NOT EXISTS"-statement in the SQL or Just check that the DB exists before querying it. If not, create it. Both seem very clumsy. Is there no way to setup a db at install time?

[android-beginners] Android and SQLite - setting up a db at install time
Hi group I am new to developing programs to the Android framework. I've read the sample exercises (http://developer.android.com/guide/ tutorials/notepad/notepad-ex1.html) but have a question regarding their database creating. All database creation happens in the function ["onCreate()" - NotesDbAdapter.java ln 67]. As I read the code, the create statement is run without checking that the DB exists. What if the db exists already? How ofthe is the function run? ... It doest override a method, but the class does not extend any class and thus does not inherint any functions to override? I've seen some work-arounds on the internet: To include a "IF NOT EXISTS"-statement in the SQL or Just check that the DB exists before querying it. If not, create it. Both seem very clumsy. Is there no way to setup a db at install time?
