# Integrity Prod Setup
> Set up Cashfree Integrity for production testing by distributing your Android app through the Play Store internal track instead of sideloading APKs.
When you install your app from a source other than the Play Store and test it in a production environment, the Cashfree mobile SDK `Android, React Native, Flutter, Cordova, Ionic, Capacitor` blocks the transaction and you get the following error.
```json json theme={"dark"}
{
"message": "com.google.android.packageinstaller is not a trusted source. App should be installed from play store or another whitelisted app store.",
"code": "installer_package_not_approved",
"type": "feature_not_enabled"
}
```
In this case, the SDK does not load the page and you get an error in the `onPaymentFailure` callback. Check the error log for details.
Below are the sample scenarios when Cashfree Integrity will fail in the `PRODUCTION` Environment ( In Sandbox, it will always work).
Trying to directly run from Android Studio/Eclipse or any IDE
Trying to install from Gallery/File Explorer/Google Drive/Slack/Whatsapp or any other link
### How to properly test in production env?
To test in production, upload your app bundle/APK to the Play Store under an internal testing environment and invite your testing team to test it.
### How to do the internal testing setup?
Internal testing is useful to quickly distribute builds to a small set of testers.
This test is used to perform the initial QA checks. You can distribute your application among 100 invited testers. The feedback from your test users won’t affect your app’s public rating it is only visible to the Developer Account.
After publishing the internal test for the first time, it may take few hours for your test link to be available to testers. After that, any new release is available in a few hours. This build is directly available for testing without review.
### Create a tester list and share the invitation
1. Open the [Play console](https://play.google.com/console/u/0/developers/9086506936822464322/app-list) and open the [Internal testing](https://play.google.com/console/u/0/developers/9086506936822464322/app/4972688618868666427/tracks/internal-testing) page under Testing.
