NullPointerException: Attempt to invoke virtual method 'void android.support.v7.app.ActionBar.setDisplayHomeAsUpEnabled(boolean)' on a null object reference

[adamvarhegyi]

So after i call:

   RingcaptchaApplication.onboard(getApplicationContext(), "my_app_key_here", "my_secret_key_here", new RingcaptchaApplicationHandler() {
                @Override
                public void onSuccess(RingcaptchaVerification ringcaptchaVerification) {
                }
                @Override
                public void onCancel() {
                }
            });

I got this exception:

By the way, your documentation is outdated:

It says in docs (https://my.ringcaptcha.com/docs/android):

"On your initial Activity, in the method hooked to the user event add the following line of code."

RingcaptchaApplication.onboard(getApplicationContext(),"{{ app_key }}", "{{ secret_key }}", new RingcaptchaHandler() {
  @Override
  public void onSuccess(RingcaptchaVerification o) {
      //Verification successful
  }
  @Override
  public void onCancel(RingcaptchaVerification o) {
      //Decide what do do if user cancelled operation
  }   
});

But there are only these onboard functions with different signatures:

onboard(Context context, String appKey, String secretKey, RingcaptchaApplicationHandler ringah);
onboard(Context context, String appKey, String secretKey, String pin, RingcaptchaApplicationHandler ringah);

RingcaptchaApplicationHandler != RingcaptchaHandler

Also the version in doc says

compile 'com.thrivecom:ringcaptcha:1.0.7@aar'

the version in github says

compile 'com.thrivecom:ringcaptcha:1.0.8@aar'

I have tried Cognalys call verification but their system got errors.
I would really like to migrate to ringcaptcha if it is working well.

Please help if you can.

@adamvarhegyi have you add:
compile 'com.android.support:appcompat-v7:21.0.3'
to your gradle dependencies ?

[adamvarhegyi]

I have

compile 'com.android.support:appcompat-v7:23.+'

[vrunoa]

@adamvarhegyi can you change it to compile 'com.android.support:appcompat-v7:21.0.3' to see if there's a compatibility problem ?
Also, is the activity where you're calling ringcaptcha API extending from ActionBarActivity ?

Do you have any code online we can review to help you?

[dilipappectual]

Not Helped Any Solutions

[vrunoa]

What is your <application android:theme="@style/AppTheme" extending from ? Does it start working if you change it to the one used in the example

[dilipappectual]

for parent="Theme.AppCompat.Light.NoActionBar" its not working for me

[vrunoa]

Can you try with; Theme.AppCompat.Light.DarkActionBar and check if works?

[dilipappectual]

No works for Themes containing
windowActionBar to false and add windowNoTitle as well and set it to true
Error :

/com.thrivecom.ringcaptcha.OnboardActivity}: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.support.v7.app.ActionBar.setDisplayHomeAsUpEnabled(boolean)' on a null object reference

Solution :

Problem still persist if i have set getSupportActionBar().setDisplayHomeAsUpEnabled(false);

Please check and get back to me. thanks in advance

Sorry not helped me .

[dilipappectual]

[vrunoa]

Hey @dilipappectual i'll try to create a simple app with the "Theme.AppCompat.Light.NoActionBar" theme, and let you know if it works. I don't longer have access to Ringcaptcha repo, i'm just trying to help
