A guide for building and installing Android apps on Meta Portal devices, including Portal+, Portal Go, and Portal TV. These discontinued devices use a modified Android system without Google Mobile Services, such as Play Services and Firebase.

It is for enabling device access, building Portal-compatible apps, configuring launcher settings, choosing compatible libraries, and sideloading apps with the Meta VR command-line tools.

It explains device-specific restrictions that can otherwise cause apps to fail to launch or install correctly.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00131	$0.03264
Opus 5	$0.00066	$0.01632
Sonnet 5	$0.00026	$0.00653

Security

Grade C, and why

portal scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Portal

This skill is for building Android apps that target Meta's Portal device family. Portal devices are discontinued (sales stopped end of 2022), but ADB is now enabled, so owners can sideload their own apps.

The hardware: Snapdragon-based Android tablets and TV sticks running a modified AOSP without Google Mobile Services. Several models, all touch or TV. minSdkVersion 28 (Android 9) or 29 (Android 10) depending on device.

This skill pairs with metavr (Meta VR CLI) — install it first. Use metavr adb in place of raw adb everywhere. See resources/hzdb.md for the one-line install (via npx), the MCP-into-your-editor setup, and the Portal-relevant command surface. The full metavr-cli skill ships in the same repo and can also be loaded for deeper reference.

Hard constraints — read before writing any code

If you only remember a few things, remember these. Each is a class of bug Portal apps hit constantly.

No Google Mobile Services. No Play Services, no Firebase, no FCM, no Play Billing, no Google Sign-In, no Google Maps SDK, no AdMob, no ML Kit. Apps with hard GMS deps will crash on launch. Pick non-GMS alternatives — see resources/app-requirements.md.
minSdkVersion ≤ 28 is required (Portal hardware tops out at API 29). For new apps, targetSdkVersion 29 is the safest default. For porting existing apps, targetSdkVersion higher than 29 usually works fine — verified empirically with targetSdk = 36. Don't waste time downgrading the target SDK of an existing app unless you observe a concrete runtime issue.
Launcher intent-filter is required. Touch devices need MAIN + LAUNCHER; Portal TV needs MAIN + LEANBACK_LAUNCHER. The DEFAULT category is not required (verified empirically on Portal — apps with only MAIN + LAUNCHER appear on the home tile grid). Without one of these, the app installs but never appears on the home screen.
App icon must include a PNG in mipmap-xxxhdpi/ as a fallback. Declare android:icon (touch) or android:banner (TV) on the launcher activity. You can also ship adaptive icons (mipmap-anydpi-v26/) and other density PNGs alongside — Portal's launcher correctly falls back to the mipmap-xxxhdpi PNG when the adaptive XML can't be rendered. Apps with only adaptive icons (no PNG fallback) will not have a visible icon on Portal.
No contacts API. No account/credentials API. READ_CONTACTS is denied. The account provider returns nothing. 5a. Basic mic capture works; the far-field / beamformed mic array does not. Standard RECORD_AUDIO opens an AudioRecord stream and delivers real audio from handset-mic (the single-channel mic). The far-field beamformed array used by "Hey Portal" wake-word is gated by a Meta-signed native permission (com.facebook.alohasdk.permission.RECORD_AUDIO_PRIVILEGED) and is not available to sideloaded apps. So basic voice features work; sideloaded wake-word detection and high-quality room-distance pickup do not. See resources/app-requirements.md § Microphone capture for details.
Touch UI for tabletop, not phone form factor. Portal sits on a counter or stand. Users interact from 50–100 cm. Hit targets ≥ 64 dp (96 dp for primary actions), body text ≥ 16 sp (18 sp on Portal+), landscape-first. Full Portal design system (typography, spacing, palette, WCAG ratios, TalkBack rules) is in resources/design-guidelines.md; for Jetpack Compose apps, resources/compose-theme.md is a copy-paste theme starter that bakes these rules into Color.kt / Theme.kt / Type.kt.
Reserve the top ~64 dp (only if your top content sits within 64 dp of the canvas edge). Portal has a persistent system overlay strip at the top: back / home buttons (top-left) and Wi-Fi / status (top-right). It floats above app content with no automatic safe-area inset. Apps whose top UI hugs the edge (edge-to-edge toolbars, sticky headers, full-bleed modals) will tuck under it. Apps whose top content naturally sits ≥80 dp below the canvas edge don't need any change. The overlay pills are white, so apps with a light background in the top region need an additional dark scrim even after inset — see resources/app-requirements.md § Top system overlay.
