* A very basic example nanoapp that just logs activity in its entry points. |
|
* Note that code wrapped in #ifdef CHRE_NANOAPP_INTERNAL is only relevant when |
|
* a nanoapp is to be statically built into the CHRE system binary, which would |
|
* make it a "system nanoapp" rather than a true dynamically loadable nanoapp. |
