Google Apps Script: Google Sheets Click Event Trigger on Mobile/Android

Google Sheets Button Event Trigger only work on Desktop Web, but it doesn't work on Mobile App (Google Drive/Google Sheets App).

To make this work, we need to create a dropdown menu in a particular cell, then listen to onEdit changed on this cell and perform the appropriate event trigger.

Create Dropdown

  • Select a cell
  • Menu: Data -> Data Validation
  • For Criteria, select List of items. Enter items separated by command: LAUNCH,None. (I only have one command currently, which is LAUNCH).
  • Click Save.

Listen to Dropdon Edit

Menu: Tools -> Script Editors and add the following functions.

function onEdit(e) {  if (e.range.getA1Notation() == 'B2') {    Logger.log(e.value);    if (e.value == 'LAUNCH') {      Logger.log('onClick');      // do something      e.range.clear();  // optional    }  }}

NOTE: This solution will work for simple tasks, but it would not work for tasks which require special permission, like make HTTP request or send email. Refer to the next section for installable triggers.

Installable Triggers

We need Installable Triggers create a trigger event which can make HTTP request.

Menu: Tools -> Script Editors and add the following functions.

function createEditTrigger() {  var ss = SpreadsheetApp.getActive();  var triggers = ScriptApp.getUserTriggers(ss);  var isTriggerExist = false;  for each (t in triggers) {    if (t.getHandlerFunction() == 'onTriggerEdit') {      isTriggerExist = true;    }  }  if (!isTriggerExist) {    ScriptApp.newTrigger('onTriggerEdit')    .forSpreadsheet(ss)    .onEdit()    .create();  }}function onTriggerEdit(e) {  if (e.range.getA1Notation() == 'B2') {    Logger.log(e.value);    if (e.value == 'LAUNCH') {      Logger.log('onClick');      onClick();      e.range.clear();    }  }}

You need to call createEditTrigger on Desktop (not Mobile).

You shall be prompted with a permission request screen.

After executing createEditTrigger once on Desktop (this only need to be run once per lifetime of this spreadsheet), you can click on the dropdown on mobile devices to trigger an event which can make HTTP request.
