When targeting Android 11 (API level 30)
When an app targets Android 11 (API level 30) or higher and queries for information about the other apps that are installed on a device, the system filters this information by default. The limited package visibility reduces the number of apps that appear to be installed on a device, from your app's perspective. This Plugin checks if Instagram installed. Because of the above, even with Instagram installed, you will end up with "Instagram app is not installed on your device"-errors as your app is not allowed to see Instagram.
Read this for more background information: https://developer.android.com/training/package-visibility
If you are using Android Gradle plugin 4.1+, your tools should work with the new <queries> declaration. However, older versions of the Android Gradle plugin are not aware of this new element.
How to solve this
In your android/build.gradle file, apply the correct Android Gradle plugin fix, as described on https://android-developers.googleblog.com/2020/07/preparing-your-build-for-package-visibility-in-android-11.html: Change the classpath 'com.android.tools.build:gradle dependency to a dot release version that is compatible with <queries>. E.g.:
buildscript {
...
dependencies {
// classpath 'com.android.tools.build:gradle:3.5.3'
classpath 'com.android.tools.build:gradle:3.5.4'
...
}
}
