I have created a modded apk using apktool but when I try to install it , it doesn't install. When I rechecked and compared it with an older apk I found out that my apk file wasn't signed. I searched a lot but couldn't find out a method to sign apk on mac OS X. Please help
Got my solution- I use keytool, Jarsigner and zipalign from JDK by using following commands in terminal
To generate keystore
keytool -genkey -v -keystore my-keystore.keystore -alias name_alias -keyalg RSA -validity 10000
To sign an apk
jarsigner -verbose -keystore <path of my-keystore.keystore> <path of apk> name_alias
To zip align an apk
zipalign -f -v 4 <your.apk > <your_aligned.apk>
MacBook User.
1.You need to create .keystore file in terminal. Put on Folder the .Keystore and Your .Apk
keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -validity 10000
-Its ok to change alias_name and my-release-key but not .keystore
2.Put this on Terminal.
jarsigner -verbose -keystore <your .keystore> space <your app file> space <your alias name on creating keystore>
then ask you Enter Password put your password in created keystore . Now you have signed apk.
Note: you have JDK Install on your MacBook.
If the apk file is already signed, remove the original sign with following code
Zip -d <path of apk> META-INF/*
To sign an apk
jarsigner -verbose -keystore <path of my-keystore.keystore> <path of apk> alias_name
To sign an apk not work and idk >=1.7
jarsigner -verbose -digestalg SHA1 -sigalg MD5withRSA -keystore <path of my-keystore.keystore> <path of apk> alias_name
To zip align an apk
~/Library/Android/sdk/build-tools/xxxxx/zipalign -f -v 4 <your.apk > <your_aligned.apk>
