@RequiresApi(KITKAT) @Override public File[] getExternalFilesDirs(String type) {
  return mBase.getExternalFilesDirs(type);
}

代码示例来源：origin: termux/termux-app

Os.symlink(moviesDir.getAbsolutePath(), new File(storageDir, "movies").getAbsolutePath());
final File[] dirs = context.getExternalFilesDirs(null);
if (dirs != null && dirs.length > 1) {
  for (int i = 1; i < dirs.length; i++) {

@Ignore
 @Test
 @Config(minSdk = KITKAT)
 public void getExternalFilesDirs() throws Exception {
  ShadowEnvironment.addExternalDir("external_dir_1");
  ShadowEnvironment.addExternalDir("external_dir_2");

  File[] externalFilesDirs =
    ApplicationProvider.getApplicationContext()
      .getExternalFilesDirs(Environment.DIRECTORY_MOVIES);

  assertThat(externalFilesDirs).isNotEmpty();
  assertThat(externalFilesDirs[0].getCanonicalPath()).contains("external_dir_1");
  assertThat(externalFilesDirs[1].getCanonicalPath()).contains("external_dir_2");

  // TODO(jongerrish): This fails because ShadowContext overwrites getExternalFilesDir.
//     assertThat(RuntimeEnvironment.application.getExternalFilesDir(Environment.DIRECTORY_MOVIES)
//         .getCanonicalPath()).contains("external_dir_1");
