Google’s New Android Side‑Load Policy: What Developers Need to Know

Advanced Installation Flow (Side‑load) Overview

On 19 Mar 2024 Google announced an “Advanced Installation Flow” that will apply to all Android devices that ship with Google Mobile Services (GMS) from 2027. The flow adds a verification step for developers and a 24‑hour waiting period for users installing apps that are not verified.

Developer verification

All developers (Google Play, side‑load, third‑party stores) must register in the Google Play Console.

Registration requires personal/legal name, address, phone number, email and a US $25 fee.

Unverified developers’ apps are blocked from installation on GMS devices.

Installation procedure for unverified apps

Enable “Developer options” on the device.

In Developer options turn off the built‑in “Advanced security” toggle for side‑load.

Reboot the device and confirm the change with the device password/PIN.

Wait 24 hours (the waiting period can be avoided if the security toggle is disabled in advance for 7 days or permanently).

After the waiting period the APK can be installed normally.

Migration and sensitive apps

The side‑load permission can be migrated when the user switches to a new device, so the flow does not need to be repeated.

After the permission is fully enabled, sensitive apps (e.g., banking) continue to work even if the developer options are later disabled.

Urgent‑install workaround

When the 24‑hour delay is unacceptable, the app can be installed via ADB, which requires a computer connection and the command: adb install path/to/app.apk ADB installation bypasses the waiting period but still respects the verification requirement (the app must be signed and the device must allow USB debugging).

Scope of the policy

Only devices that include GMS and comply with the Android Compatibility Definition Document (CDD) are affected.

Android devices sold in mainland China that lack GMS are not directly subject to the new flow, although many manufacturers are tightening bootloader‑unlock restrictions.

Key implications

Independent developers and small teams face an additional administrative and financial barrier.

The 24‑hour delay introduces a “security gate” intended to reduce the prevalence of malicious side‑loaded apps, which Google claims are up to 50 × more risky than Play Store apps.

The policy aligns Android side‑loading with iOS‑style verification in regions where iOS permits side‑load.
