Android get dialer package name

Question

I need to get package name of an app which post notification about a missed call. As far as I understand it makes dialer app of a device. Can I get package name of dialer app on the device, I need it from API 19?

Answer 1

You can filter all dialer applications using Intent.ACTION_DIAL action and PackageManager.queryIntentActivities(...). Where it will return list of applications which can dial phone.

You can use below code, as it is

public List<String> getPackagesOfDialerApps(Context context){

    List<String> packageNames = new ArrayList<>();

    // Declare action which target application listen to initiate phone call
    final Intent intent = new Intent();
    intent.setAction(Intent.ACTION_DIAL);
    // Query for all those applications
    List<ResolveInfo> resolveInfos = context.getPackageManager().queryIntentActivities(intent, 0);
    // Read package name of all those applications
    for(ResolveInfo resolveInfo : resolveInfos){
        ActivityInfo activityInfo = resolveInfo.activityInfo;
        packageNames.add(activityInfo.applicationInfo.packageName);
    }

    return packageNames;
}
