How to re-sign the OpenTV ION Android app

This page describes the steps required to re-sign an Android app using a different app ID.

Assumptions

The final app ID has been shared with NAGRAVISION and the embedded player licence for that ID is included in the app.
apktool is installed and available at the command line.
An Android keystore file has been created with the name my-release-key.keystore and passcode 123456.
A Google Play Console account has been created.

Download the release APK.
From the command line, change directory into the download folder and run the following:
Bash
```
apktool d mob-and-0.20.3.apk
```
In the folder extracted in the previous step, open the AndroidManifest.xml file in a text editor.

Modify the first line to include the required versionCode, versionName, and package:

XML

<?xml version="1.0" encoding="utf-8" standalone="no"?><manifest xmlns:
android="http://schemas.android.com/apk/res/android" android:
versionCode="1" android:versionName="1" package="com.nagra.tom.uk.
jado">

Re-package the app using the following command:
Bash
```
apktool b mob-and-0.20.3 -o resigned.apk
```

Re-sign the app using the following command:

Bash

jarsigner -verbose -sigalg MD5withRSA -digestalg SHA1 -keystore ./myrelease-key.keystore -storepass 123456 resigned.apk my-key-alias

Upload the app to the Google Play Console and submit for review.
