PackageManager pm = getApplicationContext().getPackageManager();
try {
      pm.getPackageInfo("net.basov.lws.qr.gpm", 0);
      Intent i = new Intent("net.basov.lws.qr.ENCODE");
      i.setData(Uri.parse("createqr:"));//(mondatory) set schema
      i.putExtra("ENCODE_DATA", textToEncode);//(mandatory) text to encode
      i.putExtra("ENCODE_LABEL", textToEncode);//(optional, default: same as text to encode) text above QR code
      i.putExtra("ENCODE_CORRECTION", "L"); //(optional, default: L) Error correction level [L,M,Q,H]
      i.putExtra("ENCODE_MODULE_SIZE", 6);//(optional, default 6) Small black square zize in pixels
      i.putExtra("ENCODE_MASK", -1);//(optional, default -1) QR code data mask 0-7 or -1 for autodetect
      i.putExtra("ENCODE_MIN_VERSION", 1);//(optional, default 1) Force minimal QR code version (size)                         
      startActivity(i);
} catch (PackageManager.NameNotFoundException e_lws_qr) {
      Intent i = new Intent(Intent.ACTION_VIEW);
      i.setData(Uri.parse("market://details?id=net.basov.lws.qr.gpm"));
