Android: getContext().getContentResolver() sometimes gets NullPointerException

Question

I want to ask why we get this annotation:

Method invocation getContext.getContentResolver() may produce NullPointerException

Why i

Answer 1

According to ContentProvider getContext() docs:

Retrieves the Context this provider is running in. Only available once onCreate() has been called -- this will return null in the constructor.

So the getContext() method does not return null in insert(), update() or delete(), because onCreate() will be called before these calls.

So it's OK to disable that warning for that line if you use it in such case...

//noinspection ConstantConditions
getContext().getContentResolver().notifyChange(uri, null);
