Facebook Messenger SDK for Android: crash when sharing a URL - facebook

Question

I need to use the Facebook Messenger SDK in an Android app. I want to send a URL, just as text. Since ShareToMessengerParams is too limited, I was forced to manually construct an intent as shown at https://developers.facebook.com/docs/messenger/android#integration_with_intents:
private static final String EXTRA_PROTOCOL_VERSION = "com.facebook.orca.extra.PROTOCOL_VERSION";
private static final String EXTRA_APP_ID = "com.facebook.orca.extra.APPLICATION_ID";
private static final int PROTOCOL_VERSION = 20150314;
private static final String YOUR_APP_ID = "[YOUR_FACEBOOK_APP_ID]";
private static final int SHARE_TO_MESSENGER_REQUEST_CODE = 1;
...
String mimeType = "text/plain";
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setPackage("com.facebook.orca");
intent.setType(mimeType);
intent.putExtra(Intent.EXTRA_TEXT, [MY_STRING_URL]);
intent.putExtra(EXTRA_PROTOCOL_VERSION, PROTOCOL_VERSION);
intent.putExtra(EXTRA_APP_ID, YOUR_APP_ID);
activity.startActivityForResult(shareIntent, SHARE_TO_MESSENGER_REQUEST_CODE);
This crashes with:

If I add:
intent.putExtra(Intent.EXTRA_STREAM, contentUri);
it doesn't crash but since my URL is just a link and does not point to a file, I get various errors: that the content could not be found, or, if I put a fake contentUri, the real URL I want to share is not activated upon clicking. If I remove:
intent.putExtra(EXTRA_APP_ID, YOUR_APP_ID);
it doesn't crash either but then users who have not installed my app (from which the sharing is done) do not get the Facebook Messenger "Install" button.
How can I share a web link and at the same time have users get the "Install" and "Reply" buttons as needed?
