Add Android App Links

Create Deep Links to App Content
Heck we have a whole project whose only purpose is to make this easy on Android. We are here to help you out. In Yowhatsapp we can block call of anyone, and we can also hide the last seen, status and many more. I am going to assume that there is an identity exchange. Now you can hide your online status and also last scenes. For additional information, see the following resources: But The Pirate Bay are known for their persistence.

Read data from incoming intents

Exploring Android to Android P2P

You can add more attributes to further refine the type of URI that the activity accepts. For example, you might have multiple activities that accept similar URIs, but which differ simply based on the path name. In this case, use the android: This allows your app to respond to implicit intents. Without this, the activity can be started only if the intent specifies your app component name. The following XML snippet shows how you might specify an intent filter in your manifest for deep linking.

For example, consider the following: However, it actually supports those two, plus these: Once you've added intent filters with URIs for activity content to your app manifest, Android is able to route any Intent that has matching URIs to your app at runtime.

Once the system starts your activity through an intent filter, you can use data provided by the Intent to determine what you need to render. Cancel your subscription any time.

Code We are writing code to try and answer the questions below in conjunction with Michael Rogers. Our fork is available here. There is an assumption that the users have authenticated to each other and that their communications are secure.

There is also an assumption that communication will work even when there is no Internet connectivity. I am going to assume that there is an identity exchange. It could be done locally over something like Bluetooth or remotely over email.

But we assume there is a point of exchange where configuration data can be shared. The real focus of this investigation is how can we enable handsets to communicate when they have something to say? It turns out that there is a wide range of connectivity scenarios and we need to address them all. Everyone is on the same local Wi-Fi infrastructure In this scenario users A, B and C all have their devices registered to either the same access point AP or to APs that are part of the same local network.

In theory we could then allow the devices to find each other by using either broadcast or multi-cast via a protocol like mDNS or SSDP and then establish point to point connections to allow communication. In practice many networks block broadcast and multi-cast as well as disallow devices to directly communicate to each other using local addresses over the local network. If the local network is connected to the Internet then we can potentially use an external infrastructure to enable discovery and connectivity.

We typically use TOR for that. When dealing with a locked down Wi-Fi infrastructure we can also ignore the Wi-Fi infrastructure and treat this like the ad-hoc asynchronous mesh scenario below.

So we can only communicate using local radios. In our case we assume there are long periods of time when users are not in range of each other. Therefore our group chat scenario is essentially asynchronous. Someone can add an entry to the group chat but there will be an indeterminent delay before anyone else sees their message.

We therefore assume we are using asynchronous opportunitistic meshing. We need to explore all of them to see if alone or in combination they can be used. Technologies to investigate Wi-Fi Direct In theory this is the answer to our non-Internet connected discovery scenarios.

In practice, not so much. The main issue is that Android requires user confirmation before joining a Wi-Fi Direct group. On the other hand, if one only has to join a group once and then can reconnect without explicit joining in the future then we might be able to live with this experience. For our Wi-Fi Direct investigation what we need to know for Android is: Can we discover peers while in stand by mode?

Can we be discovered by peers while in stand by mode? Can we discover services while in stand by mode? Can we be discovered by peers looking for a service on our device while in stand by mode? How long does a device have to be nearby before we will discover it?

Add intent filters for incoming links

Users following links on devices have one goal in mind: to get to the content they want to see. As a developer, you can set up Android App Links to take users to a link's specific content directly in your app, bypassing the app-selection dialog, also known as the disambiguation dialog. To allow users to enter your app from links, you must add intent filters for the relevant activities in your app manifest. These intent filters allow deep linking to the content in any of your activities. This Google-authorized android training course propels your career as a professional Android app developer.
