Example 1 with ListeningExecutorService

use of com.google.common.util.concurrent.ListeningExecutorService in project buck by facebook.

the class AdbHelper method adbCall.

/**
   * Execute an {@link AdbCallable} for all matching devices. This functions performs device
   * filtering based on three possible arguments:
   *
   *  -e (emulator-only) - only emulators are passing the filter
   *  -d (device-only) - only real devices are passing the filter
   *  -s (serial) - only device/emulator with specific serial number are passing the filter
   *
   *  If more than one device matches the filter this function will fail unless multi-install
   *  mode is enabled (-x). This flag is used as a marker that user understands that multiple
   *  devices will be used to install the apk if needed.
