Proper way to handle Android Studio's NullPointerException lint warning

Question

I\'m new to android/java programming and am confused how to properly deal with this warning.

Method invocation \'\' may produce \'Java.lang.NullPointe

Answer 1

What @Herrbert74 suggested it surely working fine, but sometimes it's better to not add a @SuppressWarnings("ConstantConditions") to an entire method (if it's not trivial), a better approach could be to use //noinspection ConstantConditions on the warned line.

Those are my rules of thumb:

• Use @SuppressWarnings("ConstantConditions") when the method is simple

• Use //noinspection ConstantConditions when the method is complex and you need to remove the warning only on a specific line
