Think of the next billion users: Building for Low End devices
summary
Half the next billion come online on $25–$80 phones with 512 MB–1 GB RAM and tiny storage, often on 2G/edge connectivity or dual‑SIM setups; users share media via SD cards and Bluetooth and favor tiny installs. Advice: aggressive caching, avoid repeated network calls, use NetworkCallback + ConnectivityManager + TelephonyManager to adapt behavior, profile render hierarchy and memory, offload heavy computation to the NDK, strip dependencies/resources, run the size analyzer and publish modular builds with the Android App Bundle to cut install size and churn.
