还安装了来自 Play 商店的应用时，由于冲突而未安装应用

Question

I'm running into an odd issue and not at all sure why.

I'm using firebase app distribution to install development-grade versions of my app and whenever I try to install a dev version of my app, it won't install claiming that the app exists already, but it doesn't.

I have the app from the store installed and upon uninstalling that, the app will then install but I don't understand why as both have different applicationIds.

the store version has: com.example.myapp & the dev version has com.example.myapp.preview and the app name is also different as is the version code and version name.

I don't get what they seem to share that is causing it to not allow both of them to coexist.

Not sure if this is important, but when I try to install the dev version, play protect will pop-up claiming the app is unknown and to be sure you trust it.

I'm hoping someone can steer me in a direction on solving this as I'm simply lost on what's causing the conflict.

here is the relevant gradle config:

android {
    compileSdk 32

    defaultConfig {
        applicationId "com.example.myppp"
        targetSdkVersion 32
        minSdkVersion 26

        versionCode verCode
        versionName "4.2.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    signingConfigs {
        development {
            storeFile file("../keystore/development.jks")
            storePassword System.getenv("DEV_SIGNING_STORE_PASSWORD")
            keyAlias System.getenv("DEV_SIGNING_KEY_ALIAS")
            keyPassword System.getenv("DEV_SIGNING_KEY_PASSWORD")
        }
        debug {
            storeFile file("../keystore/debug.jks")
            storePassword System.getenv("DEBUG_SIGNING_STORE_PASSWORD")
            keyAlias System.getenv("DEBUG_SIGNING_KEY_ALIAS")
            keyPassword System.getenv("DEBUG_SIGNING_KEY_PASSWORD")
        }
        release {
            storeFile file("../keystore/prod.jks")
            storePassword System.getenv("PROD_SIGNING_STORE_PASSWORD")
            keyAlias System.getenv("PROD_SIGNING_KEY_ALIAS")
            keyPassword System.getenv("PROD_SIGNING_KEY_PASSWORD")
        }
    }

Answer 1

I have discovered my issue, it appears I was reusing the same file provider identifier, I made that more dependent on the application id and now I'm able to install the dev app alongside my store version.

I also has add product flavors as I saw a few SO answers claim that's a better way to go about what I was looking to do.
