There is this code (taken from https://stackoverflow.com/a/5016624/1369016 ):
private boolean isAppInstalled(String packageName) {
PackageManager pm = getPackageManager();
boolean installed = false;
try {
pm.getPackageInfo(packageName, PackageManager.GET_ACTIVITIES);
installed = true;
} catch (PackageManager.NameNotFoundException e) {
installed = false;
}
return installed;
}
But I don't know what to put in the packageName. I tried com.google.android.gms.wallet
(which is the package of some Wallet fragments used by Android Pay) but the above method returns false.
It turns out the package name required is " com.google.android.apps.walletnfcrel ". With that you can call the method in the question to detect if Android Pay is installed.
on Kotlin:
private fun isAppInstalled(packageName: String): Boolean {
return try {
activity?.packageManager?.getPackageInfo(packageName, PackageManager.GET_ACTIVITIES)
true
} catch (e: PackageManager.NameNotFoundException) {
false
}
}
