Generate keyhash

Follow https://www.youtube.com/watch?v=LUv8NDgu2Xk keytool -exportcert -alias androiddebugkey -keystore %HOMEPATH%\.android\debug.keystore | openssl sha1 -binary | openssl base64 Step 1: cd to folder Java\jre...\bin
Step 2: Replace openssl by C:\openssl\bin\openssl. If we don’t have openssl, simply go to internet->download->extract.
Step 3: Run command (like the below example)
keytool -exportcert -alias androiddebugkey -keystore %HOMEPATH%\.android\debug.keystore | C:\openssl\bin\openssl sha1 -binary | C:\openssl\bin\openssl base64 Step 4 : Enter password (using empty password by enter)
Bước 5: Done
