To Check if a package is installed in android Kotlin programmatically for android 12 . Without declaring a query in the manifest file for Android 12 (API 31 ).

CodePudding user response：

private fun isAvailable(ctx: Context, intent: Intent?): Boolean {
    val mgr = ctx.packageManager
    val list = mgr.queryIntentActivities(intent!!, PackageManager.MATCH_DEFAULT_ONLY)
    return list.size > 0
}

Use this code snippet for that, Thanks.
