Answer 1

You have values for compileSdkVersion which are clashing in your MY_PROJECT_NAME/build.gradle file.

The first value you have looks something like this:

android {

    compileSdkVersion 27

and further down you have some dependencies which are using/need a HIGHER compileSdkVersion value.

SOLUTION: Try using the newest SDK, 29 as of this answer. Edit your project/build.gradle (although instead of project you will have a folder named for your specific React Native project/app).

android {
    compileSdkVersion 29

    defaultConfig {
        targetSdkVersion 29
    }
    ...
}

I got this information here: https://developer.android.com/about/versions/10/setup-sdk#update-build

Explanation: If some package/dependency you're using needs to be able to use certain android APIs that are only available in SDK 29+ but your project/build.gradle is saying "use SDK 27", your dependencies would be expecting to use APIs which wouldn't exist.
