Yes: an ARM64 Android phone can host an Android app development workflow using Termux, PRoot Debian, and ADT, with TERNUX optionally adding an Xfce desktop. The pieces have different jobs: TERNUX supplies a no-root Linux workspace and display environment; ADT supplies Android command-line build and device tools. Their shared foundation makes the combination plausible, but the projects describe the combined workflow as experimental, so validate it on the phone you intend to use.
What TERNUX and ADT each do
TERNUX: a Linux workspace and optional desktop
TERNUX uses Termux and PRoot to run a Debian userspace on an ARM64 Android device. It can provide an Xfce4 desktop through Termux:X11, but it does not install a second kernel or run a conventional virtual machine: Android’s existing kernel remains in use. Root access is not required. See the TERNUX project documentation.

ADT: Android build and device tools
ADT is a separate ARM64 toolchain layer. Its documented native tools include Android build-tools and platform-tools such as aapt2, aidl, zipalign, adb, and fastboot. It also supports JVM-based tools including apksigner, d8, R8, and sdkmanager, along with JDK, CMake, Ninja, NDK shims, and Flutter/Dart. Its main route is command-line based; an X11 desktop is optional. See ADT’s documentation.

Check whether your phone is a suitable host
TERNUX’s published requirements are project-specific, not universal minimums for Android development. Its documentation lists an ARM64/aarch64 Android device, Android 10 or newer, at least 4 GB RAM, stable network access during setup, and about 3–4 GB of storage for the base installation. It recommends 6–8 GB RAM for desktop and development use. Its full --all profile is estimated at roughly 10–12 GB, plus room for working files. Confirm available storage before choosing that profile.
- Architecture: Confirm that the device and environment report ARM64/aarch64.
- Memory: Compare available RAM with TERNUX’s published minimum and recommendation; an installed app or background service can reduce what is available to the environment.
- Storage: Budget for the selected profile, SDK components, project files, and build outputs rather than counting only the base installation.
- Graphics: If you want TERNUX’s documented Adreno Zink/Turnip route, compatibility also depends on access to
/dev/kgsl-3d0. Without it, the graphics path may differ or fall back.

Understand the Android Studio distinction
Android Developers’ Android Studio installation page states: “Linux machines with ARM-based CPUs aren’t currently supported.” That statement concerns the official Linux support status for Android Studio. It does not mean app development is impossible on ARM64 Linux: ADT documents a separate command-line toolchain route rather than claiming to make Android Studio officially supported on this platform.

Install the layers and validate them separately
Use the projects’ current installation instructions when setting up: package names, dependencies, and installer options can change. The sequence below separates installation from validation so a failure is easier to locate.

- Install Termux and establish the Debian/PRoot base. Follow the current Termux documentation and TERNUX instructions. TERNUX documents both an automatic installer and a manual Termux/PRoot Debian route. Its one-line installer downloads a remote script; if you want to inspect what will run, the TERNUX repository advises cloning the repository and reviewing its scripts first.
- Set up ADT within the supported host environment. ADT documents a guided setup with
./setup.shand an unattended bootstrap with./setup.sh bootstrap --auto. Follow its current instructions for prerequisites and the intended working directory. - Choose the documented validated profile if it fits your project. ADT’s validated profile is installed with
./setup.sh install-profile validatedand comprises build-tools 35.0.2, NDK 27.2, and android-36. ADT also marks certain build-tools 36.0.0 and 37.0.0 artifacts verified; that does not mean every package combination or version is validated. - Run the environment check. From the ADT setup context, run
./setup.sh doctor. ADT says this checks architecture, paths, JDK availability, and tool integrity. Resolve reported issues before attempting a build. - Check the desktop renderer if using TERNUX’s graphical environment. Verify the graphics path on the intended device, especially if relying on the Adreno Zink/Turnip route; a working command-line toolchain does not by itself confirm the desktop’s GPU path.
- Test a small project on the target phone. Build it, sign it, install it on the intended device, and inspect the result. Treat this as a host-specific validation step, not proof that the combined stack is supported on other devices.
Know what can be installed offline
ADT documents some offline artifacts, including build-tools and platform-tools 35.0.2 and build-tools 36.0.0. Command-line tools and Android platforms require a network connection. Building other build-tools versions from AOSP source is documented as a multi-gigabyte, time-consuming process, so it is not a quick offline substitute for the listed artifacts.
How strong is the evidence for the combined workflow?
ADT’s documentation says: “Combined cross-project workflows are observed to coexist but are not yet tested formally — they remain experimental.” It also distinguishes its pipeline verification on the shared host from TERNUX’s separate validation of the desktop/GPU stack. In other words, each project documents useful functionality, but the combined environment should be treated as an experiment to verify on your own hardware.
ADT reports a Flutter/Gradle build marked “BUILD SUCCESSFUL in 1m 21s” with 60 actionable tasks, validated on its test device on 2026-09-01. This is one project-reported result under that setup, not a speed estimate for other phones or projects.
