Android Tutorial B4A-Bridge source code

B4A-Bridge is made of two components. One component is running on the device and the other is embedded in the IDE.
The device side is the server side. It waits for connections and when a connection is established it handles the "action" messages.

The code itself is made of a simple activity:

And a service that is doing most of the job.
All the network communication is handled by an AsyncStreams object. AsyncStreams are very useful for networking and other external communication.

In this case the AsyncStreams object is initialized in prefix mode. In this mode we always receive complete messages which makes things simpler.
See this tutorial for more information: AsyncStreams Tutorial

This code is a good example for networking and working with service.
You are welcomed to examine the code and ask any question about it.

I might be wrong but it seems to me that the file "B4A-BridgeLastVersionWithBluetooth" in the first post does not contain the bluetooth-code....

 

[Erel]

You are correct. I've removed the zip. The Bluetooth version which is not supported since B4A v5 is no longer available.

 

[LucaMs]

Are you using the latest version of B4A-Bridge (2.51)?

Can you attach the last source code, Erel?

 

[Erel]

Done. The version in the source code is 2.52 (it includes a small modification that was not published).

Good job @Erel, God bless you ...

Tnx

The source code does not include the folder res . you can find them in B4A-bridge.apk.
