Verbose log of yesterday's AAB build revealed:
java.lang.OutOfMemoryError: Java heap space
at java.util.zip.DeflaterOutputStream.write
at com.android.zipflinger.StreamSource.<init>
at com.android.builder.internal.packaging.AabFlinger$writeZip$1.call
AAB packaging streams compressed native libs through ByteArrayOutputStream
buffers. With universal-bundle (all 3 ABIs in one AAB) and parallel
ForkJoinPool workers all drawing from the same 6G heap, the peak exceeds
budget mid-zip. APK build doesn't hit this because per-ABI APKs are
packaged separately, much smaller per-file working set.
Two changes:
1) org.gradle.jvmargs: -Xmx6144M → -Xmx10240M, + MaxMetaspaceSize=1024M
(the daemon-side metaspace also creeps up over a long build).
2) org.gradle.workers.max=2 — fewer parallel workers = lower simultaneous
buffer footprint. Build still parallel, just gentler peak.
