How to detect if device is capable of calling and messaging

Question

Some devices ie. Galaxy Tablet 10.1 can only send SMS, but cannot call. Some other devices like Asus Transformer don\'t even have SIM card.

How can I detect if devic

Answer 1

Here is what I make to check is SMS available.

public boolean isAvailable(Context context, Intent intent) {
    final PackageManager mgr = context.getPackageManager();
    List list = mgr.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
    return list.size() > 0;
}

which is taken from developer.android.com.

And create an Intent to check like this:

Uri smsToUri = Uri.parse("smsto:");
Intent intent = new Intent(Intent.ACTION_SENDTO, smsToUri);
if (isAvailable(intent)) {
    // do whatever you like.
}
