Is there an Android build flag to check for APK versus Instant App version of an App

Question

Just like BuildConfig.FLAVOR and BuildConfig.DEBUG is there a build flag to check at runtime for the APK version or the Instant App version of an Android application ?

Or is there another way to get the information ?

Answer 1

Add to the module build.gradle the dependency : implementation 'com.google.android.instantapps:instantapps:1.0.0' then you will be able to use the function InstantApps.isInstantApp(this).

Please note that you must use Maven Google by changing your repositories in the project build.gradle :

buildscript {
    repositories {
        maven {
            url 'https://maven.google.com'
        }
        jcenter()
    }
    ...
}

allprojects {
    repositories {
        maven {
            url 'https://maven.google.com'
        }
        jcenter()
    }
}

Answer 2

Easiest way is to use PackageManager.isInstantApp() :

https://developers.google.com/android/reference/com/google/android/gms/instantapps/PackageManagerCompat.html#isInstantApp()

Or, a regular (non-appcompat version) https://developer.android.com/reference/android/content/pm/PackageManager#isInstantApp()

Also has an override which accepts package name as a string, which allows to check other apps, if permissions allow.
