- * Java mirror of Chrome command-line utilities (e.g. class CommandLine from base/command_line.h).
- * Command line program adb_command_line can be used to set the Chrome command line:
- * adb shell "echo chrome --my-param > /data/local/chrome-command-line"
- */
+ * Java mirror of base/command_line.h.
+ * Android applications don't have command line arguments. Instead, they're "simulated" by reading a
+ * file at a specific location early during startup. Applications each define their own files, e.g.,
+ * ContentShellActivity.COMMAND_LINE_FILE or ChromiumTestShellApplication.COMMAND_LINE_FILE.
