Hello,
I am working on a Java application that use large application resources.
On the application side, I want to send the path of my resource through a native method. I use the API SNI.toCString() to send the path from the Java world to the native world like the following:
public static void main(String[] args) {
sendApplicationResource(SNI.toCString("/my_resource"));
}
public static native void sendApplicationResource(byte[] path);
I try to implement a Mock that can read the Application Resource. I made the following implementation of the native method in my mock:
public static void sendApplicationResource(byte[] path) {
// Refresh HIL instance
NativeInterface ni = HIL.getInstance();
ni.refreshContent(path);
// Get resource data
String filePath = SNI.toJavaString(path);
byte[] modelData = ni.getResourceContent(filePath);
}
This native method works well with small Application resources (e.g. 100KB) but when I want to use larger application resources (on my side more than 500KB), it throws the following error when I launch my application on the Simulator:
Exception in thread "main" @T:java.lang.UnsatisfiedLinkError@: HIL client execution exception:

Am I doing something wrong when processing my resources?
