Repackage Modify APK

Step to repackaging apk.

1. Download original apk.
2. Extrack apk with apktool.

apktool d vantagepoint.apk -o vantagepoint

3. Modify the apk.
4. Repackage apk with apktool.

apktool b vantagepoint -o vantagepoint_bank_1.apk

5. Align and Signing the APK with uber-apk-signer.

To create the certificate I used this tool [APK Signer Tool v2](https://shatter-box.com/download/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](https://github.com/patrickfav/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

6. Cek signed APK to verify the apk was sign with our certificate(optional)

keytool -list -printcert -jarfile "vantagepoint_bank-aligned-signed.apk"
