Prevent my application from being idle (Cordova/Android)

Question

Prevent my application from being idle (Cordova/Android)

I have recently developed an Android app using a node.js webpack project.

After installing the app on my phone, I observed that it enters a sleep mode along with the phone. Consequently, a JavaScript timer I set up stops functioning as intended:

pingTimer=setInterval(ping,pingInterval);

I am looking for a way to prevent my app from going to sleep, at least for the time being. Eventually, I will consider allowing the app to enter a sleep state, but for now, I need it to stay awake while the phone sleeps.

UPDATE

I attempted to follow the steps outlined in this guide:

Unfortunately, I did not achieve the desired result.

Answer №1

If you're looking for the ideal solution, consider utilizing the WakeLock API.

Include the necessary permission in the manifest file to enable the wakeLock.

<uses-permission android:name="android.permission.WAKE_LOCK" />

Subsequently, based on your modifications as suggested in MDN, you can implement the following:

function forPingTimer(){
 var lock =  window.navigator.requestWakeLock('screen');
 //set a timeout or wait until the timer expires
}

To release the lock, use the lock.unlock(); function.

Alternatively

For a Cordova application, you may also utilize the plugin Insomnia. The necessary changes in the config file are outlined in the documentation and can be easily implemented as follows:

function forPingTimer(){
//keep the app awake indefinitely or specify a timeout, or encapsulate it in a promise
//Simply call window.plugins.insomnia.keepAwake() to prevent sleep
}
//To allow the device to sleep again after the timer expires, use window.plugins.insomnia.allowSleepAgain()

To clarify the syntax, first install the cordova-plugin-insomnia plugin. Then, incorporate a basic interval timer into your code:

// initiate an interval timer
var mainloopid = setInterval(mainloop, 1000);
function mainloop {
    // invoke the plugin every (let's say) one second to prevent your app from sleeping
    window.plugins.insomnia.keepAwake();
}

Make sure to call the plugin's keepAwake method regularly (at least before your device attempts to sleep.) This is crucial for any display clocks, and the interval timer can be part of the timer responsible for updating seconds in a clock. This method essentially overrides the device setting that dictates, for instance, "sleep after 15 seconds". It's like setting an Android Device to "sleep never" mode while your app is active.
