Make logging and IntegrationValidator available from RNBranchModule

[delventhalz]

Working with a React Native project currently focused on Android. We had some issues setting up Branch initially. Logging and the IntegrationValidator would both have been useful in revealing our setup issues. We found those documented here for Branch's Android SDK:

https://help.branch.io/developers-hub/docs/android-testing

However, in a React Native project, the MainActivity does not contain the Branch module directly, it contains the RNBranchModule. The documentation was already difficult to follow (where is IntegrationValidator imported from?!), but translating these tools to React Native meant spending the better part of a day pouring over source code.

For those in a similar situation. I eventually came up with a workaround. I patched the file RNBranchModule.java to add three lines.

First, I had to import IntegrationValidator.

/node_modules/react-native-branch/android/src/main/java/io/branch/rnbranch/RNBranchModule.java:24:

import io.branch.referral.validators.IntegrationValidator;

Then I added the logging and validator to the end of the initSession method (which will eventually be called in the MainActivity).

/node_modules/react-native-branch/android/src/main/java/io/branch/rnbranch/RNBranchModule.java:220:

        Branch.enableLogging();
        IntegrationValidator.validate(reactActivity);

This worked, and allowed me to work through the setup issues I was having with our Branch setup. But it would be wonderful if in the future these methods were passed forward to RNBranchModule (and documented in the RN docs), so the process of running them could be simplified.

Thanks @delventhalz!

a little bit faster without having to dive into Branch's code:

In your .java file add

...
import io.branch.referral.Branch;
import io.branch.referral.validators.IntegrationValidator;
...

void fooBar() {
    Branch.enableLogging();
    IntegrationValidator.validate(reactActivity);
}

...
