Android - how to make my app default sms app progr

I am developing an sms blocking app. Which is working fine up to Jelly-Bean. And its not working from Kitkat to Marshmallow. I searched on google and everyone recommending to take permission from user to make it default sms app of this phone by using .

   if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
                if(!Telephony.Sms.getDefaultSmsPackage(getApplicationContext()).equals(getApplicationContext().getPackageName())) {
                    Intent intent = new Intent(Telephony.Sms.Intents.ACTION_CHANGE_DEFAULT);
                    intent.putExtra(Telephony.Sms.Intents.EXTRA_PACKAGE_NAME,
                            getApplicationContext().getPackageName());
                    startActivity(intent);
                }
            }

Manifest file :

<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
<uses-permission android:name="android.permission.READ_CALL_LOG" />

I used this code sample. It shows a dialog with messaging app of phone. My app is not showing on this list.

Now i want to show my app on this list also, so user can select my app from this list and it will be default sms app of that phone. How can i do that. Please reply with example/code-sample. Thanks.

I followed it

Not according to the code in your question. Let's review the four requirements from the blog post:

In a broadcast receiver, include an intent filter for SMS_DELIVER_ACTION ("android.provider.Telephony.SMS_DELIVER"). The broadcast receiver must also require the BROADCAST_SMS permission.

You have this, in the form of your PhoneStateReceiver.

In a broadcast receiver, include an intent filter for WAP_PUSH_DELIVER_ACTION ("android.provider.Telephony.WAP_PUSH_DELIVER") with the MIME type "application/vnd.wap.mms-message". The broadcast receiver must also require the BROADCAST_WAP_PUSH permission.

You do not have this.

In your activity that delivers new messages, include an intent filter for ACTION_SENDTO ("android.intent.action.SENDTO") with schemas, sms:, smsto:, mms:, and mmsto:.

You have this, in the form of DashboardActivity.

In a service, include an intent filter for ACTION_RESPONSE_VIA_MESSAGE ("android.intent.action.RESPOND_VIA_MESSAGE") with schemas, sms:, smsto:, mms:, and mmsto:. This service must also require the SEND_RESPOND_VIA_MESSAGE permission.

You have this, in the form of HeadlessSmsSendService.

So, add a <receiver> for WAP_PUSH_DELIVER_ACTION, following the instructions, and see if that helps.
