Solution to avoid ActivityNotFoundException when attempting to start an activity with ACTION_DIAL. This problem is common in tablets with no call capabilities.

CallValidation.java

/**
 * Method that checks whether the device has apps installed that can handle the Intents or not.
 * @param intent Intent that will be checked.
 * @return true if there are apps that can handle the Intent, false otherwise.
 */
private boolean checkAppsForIntent(Intent intent) {
    PackageManager packageManager = getActivity().getPackageManager();
    return intent.resolveActivity(packageManager) != null;
}

//Sample method
private void dialPhoneNumber(String phoneNumber){
    final Intent callIntent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:" + phoneNumber));
    final boolean canMakeCall = checkAppsForIntent(callIntent);
    if(canMakeCall){
      startActivity(callIntent);
    } else {
      showWarningDialog();
    }
}

//Method that shows a simple AlertDialog
private void showWarningDialog() {
    AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(getActivity());
    dialogBuilder.setTitle(getString(R.string.no_call_capabilities_title));
    dialogBuilder.setMessage(getString(R.string.no_call_capabilities_message));
    dialogBuilder.setPositiveButton(android.R.string.ok, null);
    dialogBuilder.show();
}
