Why is my native heap increasing? #517

Closed alless1 closed 4 years ago

As I kept turning on and off the camera, I dumpsys meminfo showed that Native Heap was rising and could not be released. Not even calling GC. I'm sure I've completely freed up resources at the Java layer. After testing, I found that this would not happen without setFrameCallback, but why? Please help me, thank you. @saki4510t

It's because I performed a mCamera.destroy() in the onFrame method; the native heap cannot be freed. It's amazing.
