ci coverage report npm docs

An npm package with pre-built binaries for android sdk tools such as adb, fastboot, mke2fs and heimdall. A convenience function helps finding the correct executable and environment variables and config options are available to manipulate the behavior.

See promise-android-tools for a full wrapper that provides async access to all tools and subcommands.


Install the library by running npm i android-tools-bin. See the documentation for detailed API information.

Optimistic detection

By default, the function will check if the requested tool is available for the current architecture and platform and fall back to returning a system command for the natively installed tool, if none is packaged.

import { getAndroidToolPath } from "android-tools-bin";
const adbCommand = getAndroidToolPath("adb");
const fastbootCommand = getAndroidToolPath("fastboot");
const mke2fsCommand = getAndroidToolPath("mke2fs");
const heimdallCommand = getAndroidToolPath("heimdall");

Pessimistic detection

To prevent falling back to native system commands, pass false as the second argument. The function will then throw an error if the requested binary is not available.

import { getAndroidToolPath } from "android-tools-bin";
try {
  const adbCommand = getAndroidToolPath("adb", false);
} catch (error) {
    "they told me choosing PowerPC architecture in the 21st century was a bad idea, but i just wouldn't listen..."

Requesting native tools using environment variables

To allow the user of a packaged NodeJS or Electron application some level of control as to wether the native tools should be used, the function provides environment variables:

USE_SYSTEM_TOOLS # if specified, no packaged binaries will be used
USE_SYSTEM_<tool> # pass the toolname in all caps (eg. USE_SYSTEM_ADB) to select which tools to use natively

Requesting native tools using the native argument

If, for some reason, you don't want to use the packaged binaries, you can use the third argument to pass an object describing which binaries you want natively and which you want packaged. You can also specify to not use any packaged binaries:

import { getAndroidToolPath } from "android-tools-bin";
const adbCommand = getAndroidPlatformTools("adb", true, { adb: true });
const fastbootCommand = getAndroidPlatformTools("fastboot", true, {
  all: true
const fastbootCommand = getAndroidPlatformTools("fastboot", true, {
  heimdall: true,
  mke2fs: true

Base directory

You can get the base directory of the packaged files by calling getAndroidToolBaseDir().

The library was originally developed for use in the UBports Installer and its promise-android-tools library, but it might be useful to other projects. Semantic versioning will ensure API stability for public functions.
