    1. COplease, add more information. Paste snippets of code here. You got `NullPointerException` on Touch MapView

    2. COPlease add your code so we can help you to find out your `NullPointException`. Its logically impossible to look like this. Well, still on, it might be because of 2 reasons. 1). You didn't made object instance for `ItemizedOverlay`, else something missing in your method `onTouchEvent`.

    3. COWe can't tell from this. Something is trying to be used before it is instantiated(it's null). If you post more code where the error is coming from we may be able to help. Also, if you put a breakpoint around the place where it is happening then you can narrow down the variable/class that is giving you the null pointer exception. Depending on what it is, you may be able to add a condition to make sure it isn't null before proceeding with the code

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
