None
Keystore • Containing “Key” and “Certification” • Every applications are
signed with keystore • The same applications are signed with the same keystore
• Valid until … • Store password: … • Key
alias: … • Key password: … • Owner informations … Keystore
debug.keystore release.keystore Signing app-debug.apk app-release.apk
The problem
The problem Where should we put the keystore?
None
• Possibility to lost keystore files • Who remembers password?
• Manual operation to share keystore files • Dull to copy them by hand Shared drive?
Shared drive? Yuck!
Put keystores in the repository
Repository • No chance to lost(we have a history!) •
Quick set up build env with just cloning • Note: Safe to share them in PRIVATE repo
None
Wait, how do we share keystore password?
Keystore password • Use `echo something_seed_value | md5` • Set
it as ENV value ‘export KSTOREPWD=…’ • Read ENV value from build.gradle
build.gradle android { signingConfigs { release { storePassword System.getenv("KSTOREPWD") keyPassword
System.getenv(“KEYPWD”) } } }
Looks Good To Me
