Question

On my Main activity:

button = (Button) findViewById(R.id.mainAddWatchButton);
button.setOnClickListener(new Button.OnClickListener() {
  public void onClick(View v) {
    startActivity(new Intent(audiovideo, CountyBrowser.class));
  }
});

CountyBrowser activity starts fine (and behaves fine, just as it should), but things like these spews out in LogCat:

10-11 19:10:41.182: INFO/ActivityManager(58): Starting activity: Intent { cmp=se.ribit.bb/.CountyBrowser }

I am using database and cursors, but the messages above contains zero information whether I’m doing something wrong or not. The activity works fine, except for these logs. If I run everything in debug-mode, the emulator throws me back to Eclipse all the time.

Am I missing something here? Anyone care for a guess of what I’m doing wrong?

Answer 1

I think you have to close the cursors before the Activity pauses. In your onPause method for the Activity that opens the new Activity, try closing the cursors.

void onPause(){
  myCursor1.close();
  myCursor2.close();
}
