Question

This might be a simple question but I just wanted to make sure I am right.

In my android application I have a constructor that uses:

activity.getApplicationContext()

The activity is passed into the constructor as a parameter.

The problem is that I am calling this class from a Service. If I make a second constructor which accepts the Service as a parameter and uses service.getApplicationContext? Will I get the same application context?

Answer 1

Will I get the same application context?

Yes. You can check the android documentation, they have provided

 getApplicationContext()

Return the context of the single, global Application object of the current process.

So it should not be changed for the whole application process.

Please also take a note of this:

getApplicationContext() generally should only be used if you need a Context whose lifecycle is separate from the current context, that is tied to the lifetime of the process rather than the current component.

Correct me if I’m wrong.

Thanks
