我似乎无法在 Android 上使用地理位置，只是出现以下错误。
[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);
});
当我运行这个时，它已经过时了几个小时，现在尝试调试如此接近放弃尝试了我能想到的一切。

更新管理使其正常工作但为什么！！！
Ok so i managed to get it working by going into my locations setting and turing them off and then on again and click Agree???? weird cant be right?
这太烦人了，我每次都必须这样做才能让位置服务正常工作？
更新我认为我遇到问题的主要原因之一是因为我在帖子布局事件侦听器上的每个加载上请求权限，这似乎解决了问题。
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();
}
});
}
似乎仍然遇到各种其他问题，每次 GPS 未激活，我都会坚持这一点并报告更新。
