How to look up a key code

204 constants in ten groups, each with the literal name, the key it stands for and the integer that reaches your code. The values were checked one by one against the android.view.KeyEvent constants in the AOSP source.

The page is static: the table ships with it, the search field filters rows inside the browser, and nothing you type is sent anywhere.

Type in the search field above the table to filter by constant, meaning or value: volume keeps the three KEYCODE_VOLUME_* rows, 112 keeps KEYCODE_FORWARD_DEL. Clear brings back all 204 rows.

Read across the row: column one is the constant to write in code, column two says which key it is, column three is the number KeyEvent reports.

Press the copy button inside the constant cell to copy just that name.

Watch the pairs that look alike: KEYCODE_DEL is 67 while KEYCODE_FORWARD_DEL is 112; KEYCODE_MUTE (91) silences the microphone and KEYCODE_VOLUME_MUTE (164) the speaker.

What the numbers mean

Where the values come from

Every number matches the constant of the same name in android.view.KeyEvent, taken from the AOSP source. KEYCODE_0 is 7, KEYCODE_A is 29, KEYCODE_UNKNOWN is 0 — these are the values the system delivers, not a row number on this page.

Digits 0–9 occupy 7–16 and the letters A–Z occupy 29–54; the numeric keypad is a separate block that starts at KEYCODE_NUMPAD_0 = 144.

Keys the framework keeps to itself

KEYCODE_HOME (3) is handled by the framework and is never delivered to applications, so an app that waits for it never gets the callback. KEYCODE_MENU and KEYCODE_BACK do arrive normally, which is why they are listed apart from the keys an app can only observe.

Some entries are hardware-specific: KEYCODE_PROG_*, KEYCODE_STB_* and KEYCODE_TV_* belong to TV remotes, and KEYCODE_BUTTON_* arrives from gamepads and joysticks through the same KeyEvent channel.

What is not in the list

This table holds 204 constants; the KeyEvent class in the current AOSP source declares 338. Rare and newer entries — KEYCODE_ASSIST, KEYCODE_SCREENSHOT, the TV input matrix, F13–F24 — are not listed, so check the Android API reference when something you expect is missing.

Only the filter and the copy buttons need JavaScript. The values themselves are plain HTML and readable with scripts switched off.
