Target not found

Error message

Target not found

What it means

`tauri android dev`/`run` with a connected device maps the device's reported ABI to one of the known Android Rust targets from cargo-mobile2's Target::all() (aarch64/armv7/x86/x86_64 triples). This expect fires when the connected device or emulator reports an architecture that is not in that list, so no build target can be selected for it.

Solutions

1. List connected devices and their ABIs: `adb devices -l`, then `adb -s <serial> shell getprop ro.product.cpu.abi`.
2. Disconnect or ignore the unsupported device; use a standard ABI device or emulator (arm64-v8a, armeabi-v7a, x86, x86_64 system images).
3. If multiple devices are attached, select a supported one explicitly instead of letting the CLI auto-pick.
4. If you genuinely need the ABI, open a feature request against tauri / cargo-mobile2 for the new target.

Example fix

# before: riscv64 device selected -> panics 'Target not found'
$ adb devices -l
emulator-5554 device ... device:generic_riscv64
$ tauri android dev

# after: launch a supported system image
$ emulator -avd Pixel_8_API_34   # x86_64/arm64 image
$ tauri android dev

# Before `tauri android dev`, verify the selected device ABI is supported
SUPPORTED="arm64-v8a armeabi-v7a x86 x86_64"
ABI="$(adb -s "$DEVICE_SERIAL" shell getprop ro.product.cpu.abi | tr -d '\r')"
echo "$SUPPORTED" | grep -qw "$ABI" || { echo "unsupported ABI: $ABI"; exit 1; }

function isSupportedAndroidAbi(abi: string): boolean {
  const SUPPORTED = new Set(["arm64-v8a", "armeabi-v7a", "x86", "x86_64"]);
  return SUPPORTED.has(abi);
}
// usage: const prop = execSync(`adb -s ${serial} shell getprop ro.product.cpu.abi`).toString().trim();
// if (!isSupportedAndroidAbi(prop)) skipDevice(serial);

When it happens

Trigger: Running `tauri android dev` while a device whose ABI is outside aarch64-linux-android / armv7-linux-androideabi / i686-linux-android / x86_64-linux-android is the selected target (e.g. an emerging riscv64 Android board, or a misreporting emulator image).

Common situations: Exotic/preview Android hardware attached during development; emulator images for new architectures; adb defaulting to the wrong device when several are connected.
