Redirect to location settings using cordova in and

问题:

Here is the requirements what i am trying to implement in my cordova android application

1. When user enters the home page check to see if the gps is enabled or not.

2. If not enabled i want to point the user to turn on the location settings.

first part is made easily with GPS detector plugin and second part is implemented using the web intent plugin.But its not working as i expected.

if(!gps){
     //gps is disabled try to show the location setting using webintent plugin
    window.plugins.webintent.startActivity(
        {
            action: window.plugins.webintent.ACTION_LOCATION_SOURCE_SETTINGS,
        },
        function() {},
        function() {
            alert('Failed to open URL via Android Intent.');
            console.log("Failed to open URL via Android Intent. URL: " + theFile.fullPath)
        }
    );              
}

I am getting this error Failed to open URL via Android Intent.

You can achieve this using the cordova-diagnostic-plugin. Once installed, you call it via JS something like:

cordova.plugins.diagnostic.switchToLocationSettings();

UPDATE

You can use cordova-plugin-request-location-accuracy to request high accuracy location mode (i.e. GPS) directly from within the app. This will show a native confirm dialog and if user agrees, GPS will be enabled automatically with requiring user to manually change settings:

function onRequestSuccess(success){
    console.log("Successfully requested accuracy: "+success.message);
}

function onRequestFailure(error){
    console.error("Accuracy request failed: error code="+error.code+"; error message="+error.message);
    if(error.code !== cordova.plugins.locationAccuracy.ERROR_USER_DISAGREED){
        if(window.confirm("Failed to automatically set Location Mode to 'High Accuracy'. Would you like to switch to the Location Settings page and do this manually?")){
            cordova.plugins.diagnostic.switchToLocationSettings();
        }
    }
}

cordova.plugins.locationAccuracy.request(onRequestSuccess, onRequestFailure, cordova.plugins.locationAccuracy.REQUEST_PRIORITY_HIGH_ACCURACY);
