Question

我似乎无法在Android上使用地理位置似乎得到以下错误。

[INFO] :   dalvikvm: Could not find method android.app.Activity.checkSelfPermission, referenced from method ti.modules.titanium.geolocation.GeolocationModule.hasLocationPermissions
[WARN] :   dalvikvm: VFY: unable to resolve virtual method 32: Landroid/app/Activity;.checkSelfPermission (Ljava/lang/String;)I
[INFO] :   dalvikvm: Could not find method android.app.Activity.requestPermissions, referenced from method ti.modules.titanium.geolocation.GeolocationModule.requestLocationPermissions
[WARN] :   dalvikvm: VFY: unable to resolve virtual method 82: Landroid/app/Activity;.requestPermissions ([Ljava/lang/String;I)V

我的代码如下。

Ti.Geolocation.purpose = "Please allow us to find you.";
//Ti.Geolocation.showCalibration = false;
if (OS_ANDROID) {
    Titanium.Geolocation.Android.LocationProvider = Ti.Geolocation.PROVIDER_GPS;
}
Ti.Geolocation.accuracy = Ti.Geolocation.ACCURACY_BEST;
Ti.Geolocation.distanceFilter = 10;

Ti.Geolocation.requestLocationPermissions(Ti.Geolocation.AUTHORIZATION_ALWAYS, function(e) {
    console.log(e);

    if (!e.success || e.error) {

        var dialog = Ti.UI.createAlertDialog({
            message : 'You do not have location permissions enabled.',
            ok : 'Got it',
            title : 'Important'
        });

        dialog.addEventListener('click', function(e) {

            if (OS_IOS) {
                Ti.Platform.openURL('app-settings:');
            }

            if (OS_ANDROID) {
                var intent = Ti.Android.createIntent({
                    action : 'android.settings.APPLICATION_SETTINGS',
                });
                intent.addFlags(Ti.Android.FLAG_ACTIVITY_NEW_TASK);
                Ti.Android.currentActivity.startActivity(intent);
            }

        });

        dialog.show();

        return;

    }

    Titanium.Geolocation.getCurrentPosition(getGeoPosition);

});

当我运行它时，它只是在这个阶段已经持续了几个小时，现在试图调试如此接近，只是放弃尝试了我能想到的一切。

完整的测试代码

    alert(JSON.stringify(_event));
}

        Titanium.Geolocation.getCurrentPosition(getGeoPosition);
    }

    // On iOS we can get information on the reason why we might not have permission
    if (OS_IOS) {

        // Map constants to names
        var map = {};
        map[Ti.Geolocation.AUTHORIZATION_ALWAYS] = 'AUTHORIZATION_ALWAYS';

            alert('Because permission are restricted by some policy which you as user cannot change, we don\'t request as that might also cause issues.');

        } else if (locationServicesAuthorization === Ti.Calendar.AUTHORIZATION_DENIED) {

            alert('You denied permission before');
        }
    }

            // Instead, probably call the same method you call if hasLocationPermissions() is true
            alert('You granted permission.');

        } else if (OS_ANDROID) {
            alert('You denied permission for now, forever or the dialog did not show at all because it you denied forever before.');

        } else {

            // We already check AUTHORIZATION_DENIED earlier so we can be sure it was denied now and not before
            Ti.UI.createAlertDialog({
                title : 'You denied permission.',

                // We also end up here if the NSLocationAlwaysUsageDescription is missing from tiapp.xml in which case e.error will say so
                message : e.error
            }).show();
        }
    });
}

geolocation();

// Handle the URL in case it resumed the app
Ti.App.addEventListener("resume", function() {
    geolocation();
});

查找最新版本...5.1.0✓ 已安装版本5.1.0。？您是否计划开发Titanium应用程序？是

Checking your environment...

You have the latest Titanium SDK release 5.1.2.GA
Congrats! No issues detected for developing cross-platform mobile apps!

appc setup complete!

更新管理工作但是为什么!!!!

好的，所以我设法让它工作进入我的位置设置并将它们关闭然后再打开并单击同意????奇怪的不对吗？

这太烦人了我每次都必须这样做以使位置服务工作？

更新我认为我遇到问题的一个主要原因是因为我在帖子布局事件监听器上的每个负载上请求权限，这似乎解决了这个问题。

 var hasLocationPermissions = Ti.Geolocation.hasLocationPermissions(Ti.Geolocation.AUTHORIZATION_ALWAYS);

 if (hasLocationPermissions) {
     alert('You already have permission.');
     Titanium.Geolocation.getCurrentPosition(getGeoPosition);
 } else {
     Ti.Geolocation.requestLocationPermissions(Ti.Geolocation.AUTHORIZATION_ALWAYS, function(e) {

         if (e.success) {

             Titanium.Geolocation.getCurrentPosition(getGeoPosition);

         } else if (OS_ANDROID) {
             alert('You denied permission for now, forever or the dialog did not show at all because it you denied forever before.');

         } else {

             // We already check AUTHORIZATION_DENIED earlier so we can be sure it was denied now and not before
             Ti.UI.createAlertDialog({
                 title: 'You denied permission.',

                 // We also end up here if the NSLocationAlwaysUsageDescription is missing from tiapp.xml in which case e.error will say so
                 message: e.error
             }).show();
         }
     });

 }

似乎仍然会遇到各种其他问题，其中GPS不会在每次生病时激活并报告更新。
