In Android Marshmallow users grant permissons to apps while the app is runing,not when they install the app so how to check and grant Permissons at Run-Time in ionic ?

You can use cordova-diagnostic-plugin to check and request Android runtime permissions:

Check a permission:

cordova.plugins.diagnostic.getPermissionAuthorizationStatus(function(status){
    switch(status){
        case cordova.plugins.diagnostic.runtimePermissionStatus.GRANTED:
            console.log("Permission granted to use the camera");
            break;
        case cordova.plugins.diagnostic.runtimePermissionStatus.NOT_REQUESTED:
            console.log("Permission to use the camera has not been requested yet");
            break;
        case cordova.plugins.diagnostic.runtimePermissionStatus.DENIED:
            console.log("Permission denied to use the camera - ask again?");
            break;
        case cordova.plugins.diagnostic.runtimePermissionStatus.DENIED_ALWAYS:
            console.log("Permission permanently denied to use the camera - guess we won't be using it then!");
            break;
    }
}, function(error){
    console.error("The following error occurred: "+error);
}, cordova.plugins.diagnostic.runtimePermission.CAMERA);

Request a permission:

cordova.plugins.diagnostic.requestRuntimePermission(function(status){
    switch(status){
        case cordova.plugins.diagnostic.runtimePermissionStatus.GRANTED:
            console.log("Permission granted to use the camera");
            break;
        case cordova.plugins.diagnostic.runtimePermissionStatus.NOT_REQUESTED:
            console.log("Permission to use the camera has not been requested yet");
            break;
        case cordova.plugins.diagnostic.runtimePermissionStatus.DENIED:
            console.log("Permission denied to use the camera - ask again?");
            break;
        case cordova.plugins.diagnostic.runtimePermissionStatus.DENIED_ALWAYS:
            console.log("Permission permanently denied to use the camera - guess we won't be using it then!");
            break;
    }
}, function(error){
    console.error("The following error occurred: "+error);
}, cordova.plugins.diagnostic.runtimePermission.CAMERA);
