hello! I don't know how to use ToApp block in simulink. I just know we can use this block to send some data to another application that is written if I'm right. can anyone guide me how to use it? I've read all of the documentations but could not understand. I've written an android code in java. should I use the java code created by simulink in my code or I should do something else?

The ToApp block is used to send data between the host and the generated app. The method that you specify in the block mask will be invoked at every Simulink step. Basically, it provides a way to access data sent by Simulink in your Android app.
Please refer to the example here
Also note that you would need to create this method in java (in the main activity). Your custom java code should be present within this method.
I hope this helps!

This isn't working as advertised.
I can place the ToApp block in my model, enter the name of my custom method in the block dialog, and it builds and deploys properly - although my method has not yet been defined in the main activity model-name.java
Following the call-chain of the generated code, it would appear that my custom method does indeed need to be placed in this file. But, I would then need to re-build the model so that my custom code is properly included in the app that is deployed.
However, the Simulink build re-generates this file every time that it is invoked - over-writing any changes I make (including the addition of my custom method). The file is not stable, so I can't add code there and have it be included in any subsequent builds.
Do I HAVE to import the generated code to Android Studio in order to fully implement this function? If I add more blocks to the model and have to re-build from Simulink, how can I make the build keep my original custom method?
