Receive data from Android app

Library

Simulink Support Package for Android Devices / Advanced

Receive data from a method in an Android app. The method must exist in the default activity.

Choose the Method name from an Android app. Set the Data type and Data size parameters to the return values of the method.

For example, suppose that the method:

Then, set:

The method in the Android app must send a data type that this block can accept.

Note

During simulations without hardware, this block outputs zeros. See Block Produces Zeros or Does Nothing in Simulation.

Method name

The name of the method in the Android app. You must add the method to the default Activity by modifying the generated app.

Data type

The data type of the data returned by the method.

Data size (N)

The number of data elements the method returns to the block each time it runs.

Sample time

Specify how often the block reads the function.

Smaller values require the processor to complete the same number of instructions in less time, which can cause task overruns.
