The APK runtime uses about 110MB RAM plus whatever the applications consume.
The memory consumption of apps varies significantly, but each
app is typically in the range of 5 to 50MB.
To make the most efficient use of system memory, the
apkruntime-start.sh script creates
adaptive partitions for the APK runtime. There are four partitions, with execution budgets
(specified in
apkruntime-start.sh) as follows:
| Partition |
Budget (%) |
| System (outside APK runtime) |
60 |
| Foreground (APK runtime) |
40 |
| Background |
0 |
| Stop |
0 |
Note:
The total execution budget is always made available to APK
runtime; therefore if system resources are available, APK
runtime can consume up to 100% of the budget. If there are
other processes or threads consuming system resources,
you can be assured that APK runtime will still have at
least 40% of the execution budget.
For more information about adaptive partitioning, see the Adaptive Partitioning User's Guide.
