Steps were taken to add Firebase and One Signal Plugins for Android:

Step 1:
Was getting unidentified error so to get identifiable error, downgrade the one signal version by changing One Signal/Editor/OneSignalEditorScript/ Android Support Version + => 27+

Step 2:
After that started getting Dex Limit Error. To remove you need to start building Android Project using Gradle
Follow step given on this link: here
       

Step 3:

After that when you start building for Gradle you can get an error like Building Error or Gradle Build Failed
Ex.  Build-in class shrinker and multidex are not supported yet
Remove

useProguard **PROGUARD_DEBUG**

from the [android] -> [buildTypes] -> [debug] block.

Remove

useProguard **PROGUARD_RELEASE**

from the [android] -> [buildTypes] -> [release] block.

To remove issue you need to make sure if build.gradle is correct.
Problem that I faced was:
If you are using Pro Gaurd to minify then make sure to add

buildTypes {
  debug {

  }
  release {
  minifyEnabled true
           shrinkResources true
  }
}
If not using minify put false in both place.

try bellow link it gives solution to every problem you will encounter
https://gist.github.com/yatyricky/3045db85191c410da44029b0c7b7aaf6

Step 4:

If started getting error like DaydreamApi Warning then remove minify enables in debug
buildTypes {
  debug {
minifyEnabled true
  }
Use progaurd file and add
-dontwarn com.google.vr.ndk.base.DaydreamApi


Step 5:

If getting error like
Resource '@integer/google_play_services_version' not found in AndroidManifest.xml

Copy
<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

from
Assets/GooglePlayGames/Plugins/Android/GooglePlayGamesManifest.plugin/AndroidManifest.xml
To
Plugins/Android/AndroidManifest.xml

Making a website https using Apache(httpd) and tomcat on Windows Server

Getting SSL certificate from Seller:

1.       Hit command openssl on windows command prompt at windows server

2.       If no openssl command recognized install openssl first.

3.       After installation goto https://www.digicert.com/easy-csr/openssl.htm

4.       Fill the form and generate the command , copy and paste the command in server                 command prompt and execute it

5.       This will generate websitename.csr and websitename.key

6.       Upload the websitename.csr while purchasing the ssl certificate

7.       Seller will give server.crt and bundle.crt (maybe with different names)

8.       Keep the websitename.key which will be needed by apache webserver.

Configuring Apache for SSL :

    1.     Install apache of latest version with openssl .Check if extracted apache folder has               mod_ssl and mod_rewrite .

2.    Setup procedure for Apache with ssl :

 a.    Seller will give bundle.crt and server.crt as we discuss earlier, store this in                      apache/conf folder .Put websitename.key also in apache/conf folder.Rename                websitename.key to server.key

b.     Edit httpd.conf file located  in conf folder of apache

        i.   Delete # sign in front of LoadModule ssl_module  modules/mod_ssl.so

        ii.  Delete #sign in front of    Include conf/extra/httpd-ssl.conf

c.       Edit httpd_ssl.conf located in conf/extra folder of apache

      i.  Modify following section according to your need

<VirtualHost _default_:443>
  ServerAdmin some@email.com
  DocumentRoot "Your Root folder location"
  ServerName www.domain.com:443
  ServerAlias domain.com:443
  ErrorLog "logs/anyFile-error.log"
  CustomLog "logs/anyFile-access.log" common
  SSLEngine on

  SSLCertificateFile "C:/Program Files/Apache Software Foundation/Apache2.2/conf/server.cert"

 SSLCertificateKeyFile "C:/Program Files/Apache Software Foundation/Apache2.2/conf/server.key"
 </VirtualHost> 

      ii.  Make sure that "SSLCertificateFile" and "SSLCertificateKeyFile" are properly located.

 3.   Edit settings in windows advance firewall setting

i.      Modify ApacheWebserver port to any option or add 443 with 80 in inbound rules table

ii.    Or you can add exception in windows firewall for TCP port 443

   4.  Restart the apache webserver .

   5.  You may  get an error while starting the apache webserver, Read the Details from Error      Log or can see the error in event viewer . 

            a.   If the error is    “Error: 185073780 error:0B080074:x509 certificate                                                     routines:X509_check_private_key:key values mismatch”

          view the certificate modulus using the following command:

          openssl x509 -noout -text -in certfile -modulus

          view the key using the following command:

         openssl rsa -noout -text -in keyfile –modulus

                  If modulus are different reissue the request to get server.crt.

              b. Syntax error on line 51 of /usr/local/apache2/conf/extra/httpd-ssl.conf

                    Invalid command 'SSLCipherSuite', perhaps misspelled or defined by a module                             not included in the server configuration 

                  Uncoment the following line from httpd.conf by removing # sign and save it. 

                  LoadModule ssl_module modules/mod_ssl.so  .  

              c.  Syntax error on line 76 of  SSLSessionCache: 'shmcb' session cache not supported                        (known names: ). Maybe you need to load the appropriate socache module                                    (mod_socache_shmcb?).

                   Uncoment the following line from httpd.conf by removing # sign and save it. 

         LoadModule socache_shmcb_module modules/mod_socache_shmcb.so                 

              d. Apache may stop responding on http but respond on https or Apache hangs & needs                     restarting regularly due to commodo filter .  Just add following lines 
                       
                    AcceptFilter http none
          AcceptFilter https none

                  For more details please visit this Link

4         4     After installing it as a service run the service and hit the url http://localhost to see if its                   working or not .

5         5     You can change the home page in 

                  C:/Program Files/Apache Software Foundation/Apache2.2/htdocs

6         6     Now our job is to show the tomcat/webapps/Root indexpage  when localhost is hit on               browser instead of  htdocs index page .

7         7     First go to the server.xml of tomcat/bin and uncomment the line 

<                    Connector port="8009" protocol="AJP/1.3"  redirectPort="8443" />  

                 and save it (note run note as admin to  save ).

8         8    Then download the mod_jk.so from the  http://tomcat.apache.org/connectors-doc/                         binaries which  should be suitable for your apache webserver version.

9         9     Paste the mod_jk.so file to apache/modules where all other .so are kept

1        10  Create workers.properties file in apache/conf folder paste the following and save it.

               worker.list=jk-status

               worker.jk-status.type=status               worker.jk-status.read_only=true               worker.list=jk-manager               worker.jk-manager.type=status               worker.list=jk-status               worker.jk-status.type=status               worker.jk-status.read_only=true               worker.list=jk-manager               worker.jk-manager.type=status               worker.balancer.error_escalation_time=0               worker.balancer.max_reply_timeouts=10               worker.balancer.balance_workers=node1               worker.node1.reference=worker.template               worker.node1.host=localhost               worker.node1.port=8109               worker.node1.activation=A               worker.balancer.balance_workers=node2               worker.node2.reference=worker.template               worker.node2.host=localhost               worker.node2.port=8209               worker.node2.activation=A               worker.template.type=ajp13               worker.template.socket_connect_timeout=5000               worker.template.socket_keepalive=true               worker.template.ping_mode=A               worker.template.ping_timeout=10000               worker.template.connection_pool_minsize=0               worker.template.connection_pool_timeout=600               worker.template.reply_timeout=300000               worker.template.recovery_options=3               worker.list=ajp13               worker.ajp13.port=8009               worker.ajp13.host=localhost               worker.ajp13.type=ajp13               worker.ajp13.lbfactor=1

1         11     Now Edit the httpd.conf file in apache/conf, paste the following

                       LoadModule jk_module modules/mod_jk.so
               JkWorkersFile conf/workers.properties
               JkShmFile  conf/mod_jk.shm
               JkLogFile  logs/from_apache_mod_jk.log
               JkLogLevel info
               JkLogStampFormat "[%a %b %d %H %M %S %Y]"

Customize the Apache web server

•     Adding our own web pages:

      Web pages are added either in htdocs which is a default directory set in https.conf file or you can change the directory path by changing Document Root and making changes in directory label which already has default path

•        Virtual host configuration:

1.     Virtual host has two types :

                                 I.   Different domain names (use for different website on same server) with same Ip address on same server.

                                 II.   Different domain names with different ip address on same server

2.    Add a domain name and own ip address in host file of windows.

3.    Add a line “  Include conf/virtual-hosts.conf” at the end of httpd file.

4.    Create virtual-hosts.conf file in conf folder.

5.    Add these line

 NameVirtualHost *:8080

<VirtualHost *:8080>

    

       ServerName www.localhost.com

        DocumentRoot "D:/website/web1"

       

        CustomLoglogs/www.localhost.com.access.logcombined

        ErrorLog logs/www.localhost.com.error.log

</virtualHost>

6.    You can add more than one tab of virtual host if want to assign more domain names.

7.    Change host file respectively

8.    Add Respective directory tab in httpd.conf file which will locate the website in system.

9.    Restart http.exe by closing it by ctrl+c and start it by double click on it.
