Step to repackaging apk.
-
Download original apk
-
Extrack apk with apktool
apktool d vantagepoint.apk -o vantagepoint -
Modify the apk
-
Repackage apk with apktool
apktool b vantagepoint -o vantagepoint_bank_1.apk -
Align and Signing the APK with uber-apk-signer.
- To create the certificate I used this tool APK Signer Tool v2, the tool has a GUI and these tools is capable to do align and singing the apk also.
- Download : Uber-Apk-Signer
java -jar uber-apk-signer-1.1.0.jar -a vantagepoint_bank.apk --ks vantagepoint.jks --ksAlias vantagepoint-pass --ksKeyPass 1234567 --ksPass 1234567 -o vantagepoint_bank_release -
Cek signed APK to verify the apk was sign with our certificate(optional)
keytool -list -printcert -jarfile "vantagepoint_bank-aligned-signed.apk"
