How to increase heap size?

[zpdpnn]

Hello,
I am trying the doorbell example with raspberry pi 3. The app can only use 11 to 12M memory and it takes more than 3 minutes to show the annotation results.

The log shows that the app hangs up due to gc. Please check the log below:
Could you please suggest how to increate heap size? I have tried android:largeHeap="true" and it doesn't work.

Thanks.

Hi,

I am having a similar problem.

For me it looks like that android things does not allow more than 16M of memory to be given to the application, even if there is more 1 GB of memory available.

I tried different settings and what I have seen normally the available memory is defined by setting different screen resolutions, but this does not really apply to this application.
