I read that Android Java applications have a limitation for heap memory. I would like to know if WebView content is allocated on that heap or it uses C allocation.

I read that Android Java applications have a limitation for heap memory. I would like to know if WebView content is allocated on that heap or it uses C allocation.
Based on my observations of viewing my Android app memory using DDMS/MAT, the WebView has a minimal footprint in the heap and any memory used by applications within the WebView are allocated directly from system memory, avoiding the heap.
My application is quite large, 30+ MB on lauch, and the WebView still only reports a minimal size on the heap, I think it was between 300K-400K.
Use Dalvik Debug Monitor (DDMS) to capture a memory dump.
Use Eclipse Memory Analyzer Tool (MAT) to analyze the dump.
Watch this video for a tutorial on how to use these tools to examine your Android memory usage and prove to yourself this is true:
