Unibozu opened a new issue #141: Denying Android location permission triggers pause/resume cycle URL: https://github.com/apache/cordova-plugin-geolocation/issues/141 Hi, The geolocation plugin triggers a `pause` and `resume` event when you deny the location permission multiple time and then tick "Do not ask me again". This doesn't happen if you remove `cordova-plugin-geolocation` but the permission is not requested. I would not expect these events to be triggered all the time, as it can have some annoying side effects in the application. Example: we use an interval to manually request a new location every few seconds when using the app, `geolocation.getCurrentPosition` is called when the timer is fired, which can actually happen when the app is in background (I'm thinking to ask more about this on the **cordova-android** repo as this is unexpected). Generally not a problem, however with `cordova-plugin-geolocation` triggering its own `resume` event when the app is in the background, the app is re-opened automatically. We're looking at changing the implementation to manually stop all timeout and interval when the app is paused, which will fix the issue, however I think it's worth looking into `cordova-plugin-geolocation` to fix or document this behaviour. ### POC ``` cordova create test-geolocation && cd test-geolocation cordova platform add android corvova plugin add cordova-plugin-geolocation ``` Replace `www/index.html` with the one provided ```html <!DOCTYPE html> <html> <head> <meta name="format-detection" content="telephone=no"> <meta name="msapplication-tap-highlight" content="no"> <meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width"> <link rel="stylesheet" type="text/css" href="css/index.css"> <title>Hello World</title> <style> #log {height: 300px;overflow-x:auto;font-family: monospace;font-size: 12px;margin: 10px;padding:10px;border: 1px solid #999;text-transform:none;} #log div {padding: 3px 0;border-bottom: 1px solid #ccc;} </style> </head> <body> <div> <h1>Geolocation background test</h1> <button onclick="$log.innerHTML = '';" style="float: right;">clear log</button> <button onclick="request()">request()</button> <br> <div id="log"></div> </div> <script type="text/javascript" src="cordova.js"></script> <script> const $log = document.getElementById('log'); function log(...args) { args.map(function (line) { const div = document.createElement('div'); div.innerText = new Date().toISOString().replace(/^.+T/g, '') + ' - ' + line; $log.prepend(div); }); console.log.apply(console, args); }; document.addEventListener('resume', () => log('event received: resume')); document.addEventListener('pause', () => log('event received: pause')); requestWrappedInTimeout(); function request() { log('request()'); log('geolocation.getCurrentPosition()'); navigator.geolocation.getCurrentPosition( (res) => log('geolocation response - ' + JSON.stringify(res)), (err) => log('geolocation error' + JSON.stringify(err))); } </script> </body> </html> ``` Run on a device (I have not tested with an emulator) `cordova run android --device`. Tap on the "request" button, then deny the permission, check "do not ask again" and keep tapping on "request()" you will be able to see "pause" and "resume" events around the geolocation error callback. Confirmed on a Samsun Galaxy S7 running Android 7.0, and a OnePlus 6T running Android 9.0.11, and a few customers had the same issue too. If you want to trigger the app taking focus of the screen, redo the steps totick "do not ask again", add `setTimeout(() => request(), 10000)` and go back to the homescreen. The app will reappear automatically after 10 seconds.
