Realgram 0.9.150 Android preview (arm64)

Test-only Android build from passed CI checks. Package com.realgram is separate from existing 0.9.149 installation, which is preserved. Debug-signed; not a production update. Android background incoming-call FCM is not yet configured. Do not use as a production security-sensitive app.

Realgram Android native runtime v1

Hash-pinned native runtime executables migrated from the existing verified Android source. Build input only; this is not an application release.
