I don't know what type of code is necessary and where should I add?

Have you implemented any drop-down? Have you tried to fill it with country codes? — OneCricketeer, Jul 21 '18 at 13:08
Nope, I have to manually type +91**** I also don't know how to do that. Please check my app, you'll understand chat app: https://play.google.com/store/apps/details?id=com.jimmytrivedi.lapitchat — Palak Singh, Jul 21 '18 at 13:24
No one here will download a random app from the store, sorry — OneCricketeer, Jul 21 '18 at 13:25
If you'd like assistance, please edit your question to include a [mcve] of the code you've tried. By the way, no searches at all helped you? https://stackoverflow.com/questions/9760341/retrieve-a-list-of-countries-from-the-android-os and http://androiddhina.blogspot.in/2015/08/android-get-list-of-countries-in-spinner.html — OneCricketeer, Jul 21 '18 at 13:27
Well, you don't need Firebase at all to get a list of countries, so again, please show a **minimal** attempt at a solution to your problem based on those links I just sent — OneCricketeer, Jul 21 '18 at 13:36
I've checked, but I don't understand that which code should I cut? Actually where can I put this code and all? and which library? please help — Palak Singh, Jul 21 '18 at 13:38
I didn't say anything about a library. You can cut all of what you have added to the question. None of it needs to be there to create a super simple example of a country code drop-down list... If you actually want to capture the *phone number country codes*, you can just build a Hashmap in your code — OneCricketeer, Jul 21 '18 at 13:41
How can I do that? Can you please post the answer as a code, Surely I'll accept it — Palak Singh, Jul 21 '18 at 13:48

Try this lib: CountryCodePicker

 dependencies {
      implementation 'com.hbb20:ccp:2.2.2'
    }

In XML

<com.hbb20.CountryCodePicker
                    android:id="@+id/country_picker"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_centerVertical="true"
                    android:gravity="center|center_vertical"
                    android:includeFontPadding="false"
                    android:textColor="@color/text_black"
                    app:ccp_showNameCode="false"
                    app:ccp_textSize="@dimen/small_text_size" />

In Activity

CountryCodePicker country_picker = findViewById(R.id.country_picker);
String country_code = country_picker.getSelectedCountryCode();

Can you refer me any good youtube tutorial to implement this library? – Palak Singh Jul 21 '18 at 13:52
I did allowback=false, because of previous login issue in api 23, but in this library it is true, so Manifest merger failed. How can I solve? – Palak Singh Jul 21 '18 at 14:15
