### Question:
Utils { public static synchronized boolean hasExternalMemory() { boolean hasExternalMemory = false; try { hasExternalMemory = Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED); } catch (Exception e) { hasExternalMemory = false; } return hasExternalMemory; }  static synchronized Map<String, String> getMemoryInfo(Context context); static synchronized boolean hasExternalMemory(); static synchronized long getTotalExternalMemorySize(); static synchronized long getAvailableExternalMemorySize(); static synchronized long getTotalInternalMemorySize(); static synchronized long getAvailableInternalMemorySize(); static synchronized long getTotalRAM(Context context); static synchronized boolean isConnected(Context context); static synchronized boolean isWifiEnabled(Context context); static synchronized String getNetworkType(Context context); static synchronized Map<String, String> getDisplayInfo(Context context); static synchronized String getScreenDensity(Context context); static synchronized int getScreenHeight(Context context); static synchronized int getScreenWidth(Context context); static synchronized String asEmpty(String value); static synchronized String getCountryCode(Context context); static synchronized String getCountryName(Context context); static synchronized Map<String, String> getLocaleInfo(Context context); static synchronized String getLanguageCode(Context context); static synchronized String getLanguageName(Context context); static synchronized String getTimezone(); static synchronized String getVersionName(Context context); static synchronized String getVersionCode(Context context); static synchronized Map<String, String> getPackageInfo(Context context); static synchronized Map<String, String> getBuildInfo(); static synchronized String getUUID(Context context); static final String NETWORK_TYPE_WIFI; static final String NETWORK_TYPE_MOBILE; }### Answer:
@Test public void shouldBeAbleToCheckIfDeviceHasExternalMemory() { boolean hasExternalMemory = Utils.hasExternalMemory(); assertThat(hasExternalMemory, is(notNullValue())); }
