One TF card. Both systems.
Split a microSD card between Android app storage and a Linux game library with a single slider. Smart TF Card Allocator (智能TF卡分配器) is the Android companion to Armada Installer for handhelds running Android and ArmadaOS.

Allocating space erases the entire selected TF card. Back up your files first. This is a repartitioning tool; it cannot resize existing partitions without erasing them.
- Choose how much space goes to Android and Linux, with a live capacity estimate. The middle of the slider (an Android share of 10%–90%) creates a mixed card; either end gives the whole card to a single system.
- Set up Android adopted storage for supported apps and their data, including a card that is entirely Android storage.
- Prepare a companion partition that Armada Installer can recognize and format as a Linux game library, or hand the whole card to Linux.
- Use Shizuku on an unrooted device, or start Shizuku with root on a rooted device.
- Work on non-root firmware that blocks reading the card's hardware CID: the app identifies the card by its volume instead, so no root or security setting is needed. A Linux share created this way needs Armada Installer 0.5.0 or later; cards with a readable CID keep the existing flow.
- Use the dark interface with touch or a controller, with a layout suited to landscape handheld screens.
- Switch between English and Simplified Chinese in the app.
- Turn runtime logs on or off and copy them when reporting a problem.
- Android 8.0 or later and a microSD card slot.
- Firmware that supports Android adoptable storage. Availability depends on the device firmware.
- Shizuku installed, running and authorized for this app.
- For the Linux side: ArmadaOS installed on internal storage and an Armada Installer version with TF game library support. An all-Linux card needs that version; if the firmware hides the card's hardware CID, the Linux share also needs Armada Installer 0.5.0 or later. An all-Android card needs no Linux step.
This app does not install ArmadaOS. For system images and device support, see the official ArmadaOS project.
- Back up the TF card, then install the APK from Releases.
- Start Shizuku and authorize Smart TF Card Allocator. On Android 11 or later, wireless debugging lets you start Shizuku on the device without root. For other startup methods, follow the official Shizuku guide and the instructions shown by your installed version. After a reboot, start Shizuku again if needed.
- Open the app, select the TF card and use Rescan if needed.
- Move the slider to choose the split. The ends give the whole card to one system; the 10%–90% Android range shares the card. Capacities are approximate and allow for Android storage metadata.
- Select Confirm allocation plan, check the selected card and sizes, then select Erase & partition to proceed.
- Keep the card inserted and the app open until allocation finishes and, if you kept a Linux share, the Linux handoff write also finishes. If only the handoff write fails, use Retry write. An all-Android card finishes with no Linux step.
- If you allocated Linux space, boot ArmadaOS from internal storage. In Armada Installer, choose TF game library, select the matching card and follow the prompts to format and mount its Linux partition and connect the game library.
| Component | Responsibility |
|---|---|
| Smart TF Card Allocator — Android | Allocate the card, initialize Android adopted storage and prepare the Linux handoff |
| Armada Installer — ArmadaOS | Recognize the companion partition, format it for Linux and mount it for the game library |
Only apps supported by Android and the device firmware can use adopted storage. The allocator does not move apps automatically. Android adopted storage is encrypted and tied to the device; it is not a portable shared drive. Once the Linux partition is formatted for Linux, Android may no longer be able to read it.
