Exception when authenticating with wrong verification code

I'm using Firebase Phone Authentification to verify users accounts. When I try to authenticate with a wrong verification code, I get an IllegalArgumentException. Is there any way to fix that without using try catch blocks?

Here is the exception message :

java.lang.IllegalArgumentException: Cannot create PhoneAuthCredential without either verificationProof, sessionInfo, or temporaryProof.
                                                                 at com.google.android.gms.common.internal.zzbq.checkArgument(Unknown Source)
                                                                 at com.google.firebase.auth.PhoneAuthCredential.<init>(Unknown Source)
                                                                 at com.google.firebase.auth.PhoneAuthProvider.getCredential(Unknown Source)
                                                                 at com.example.myApp.testFragment$3$4.onClick(testFragment.java:316)
                                                                 at android.view.View.performClick(View.java:5197)
                                                                 at android.view.View$PerformClick.run(View.java:20926)
                                                                 at android.os.Handler.handleCallback(Handler.java:739)
                                                                 at android.os.Handler.dispatchMessage(Handler.java:95)
                                                                 at android.os.Looper.loop(Looper.java:145)
                                                                 at android.app.ActivityThread.main(ActivityThread.java:5951)
                                                                 at java.lang.reflect.Method.invoke(Native Method)
                                                                 at java.lang.reflect.Method.invoke(Method.java:372)
                                                                 at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1400)
                                                                 at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1195)

And here is the line where I get the error :

PhoneAuthCredential credential = PhoneAuthProvider.getCredential(verificationCode, inputCode);

I'm intentionally using wrong verification code in inputCode and hoping to get an error message instead of the exception.

It returns an exception so the aim should be to catch the exception it throws in the debug console. I do that by wrapping the portion of that code in a try catch and Toast it out for the user of the aim to see rather than the usual crash which isnt visible to the End Users.

Like this...

private void verifyCode(String code) {
    try {
        PhoneAuthCredential credential = PhoneAuthProvider.getCredential(verificationId, code);
        signInWithCredential(credential);
    }catch (Exception e){
        Toast toast = Toast.makeText(this, "Verification Code is wrong", Toast.LENGTH_SHORT);
        toast.setGravity(Gravity.CENTER,0,0);
        toast.show();
    }

}

Calls to PhoneAuthProvider.getCredential(...) return a PhoneAuthCredential object, which is defined as:

Wraps phone number and verification information for authentication purposes.

So getCredential() cannot return an error message. Instead it throws an exception if there is a problem with the verification/credential information you provided.
