How Can I Fix This? "method Invocation 'isemailverified' May Produce 'java.lang.nullpointerexception'"

I tried to solve it but I can not do anything, I always get the NPE even with the try and catch, I do not know what else to do, please some help, what is the correct way to remove

Solution 1:

Try-catch in this situation will prevent your app from possible crash. That is just a Lint warning.

If you want to remove the warning. First check if the variable user is null.

if (user == null){
    // show errorreturn;
}
// your code

Solution 2:

Before calling isEmailverified check for user. User may be null, so when you try to call a method on null compiler will through null pointer exception.

Try if( user != Null and user.isEmailVerified)

Solution 3:

If you are using mAuth to log your users you can try

if(mAuth.getCurrentUser() != null) {

//do your stuffif(user.isEmailVerified()){ ...}

}

or

if(((mAuth.getCurrentUser() != null)&&(user.isEmailVerified()))) {

//do your stuff
   Log.d(TAG, "onComplete: success. email is verified."); ....

}

before you ask for the method isEmailVerified();

so you can guarantee that you have an user connected before requesting information from them
