Android &引用；位置提供商要求访问“位置许可”；即使我使用运行时请求权限
这太奇怪了。我们都知道，如果Android &引用；位置提供商要求访问“位置许可”；即使我使用运行时请求权限,android,gps,locationmanager,targetsdkversion,Android,Gps,Locationmanager,Targetsdkversion,这太奇怪了。我们都知道，如果设置为23+，除了在清单中声明之外，还必须请求运行时权限 多年来，这项工作一直没有任何问题。现在的问题是，当我将targetSdkVersion设置为“26”时，LocationManager不再工作！并抛出以下错误： "gps" location provider requires ACCESS_FINE_LOCATION permission 我在我的应用程序中唯一改变的是targetsdkversion从23到26，它破坏了应用程序！有什么想法吗？试试这个完整
"gps" location provider requires ACCESS_FINE_LOCATION permission
我在我的应用程序中唯一改变的是targetsdkversion从23到26，它破坏了应用程序！有什么想法吗？试试这个完整的解决方案 在清单中添加权限
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

好的，我可以解决这个问题，我会在这里解释，以防其他人遇到类似的问题。我应该补充一点，虽然这个问题现在已经解决了，但感觉像是Android上的一个bug或者缺少文档
由于一些内部项目原因，我请求如下位置许可：
PackageInfo packageInfo = pm.getPackageInfo(_activity.getPackageName(), PackageManager.GET_PERMISSIONS);
String[] requestedPermissions = null;
if (packageInfo != null)
{
requestedPermissions = packageInfo.requestedPermissions;
if (requestedPermissions.length > 0)
{
List<String> requestedPermissionsList = Arrays.asList(requestedPermissions);
_requestedPermissionsArrayList = new ArrayList<String>();
_requestedPermissionsArrayList.addAll(requestedPermissionsList);
}
}
for(int i=0; i < _requestedPermissionsArrayList.size(); i++)
{
if(_requestedPermissionsArrayList.get(i).equals(Manifest.permission.ACCESS_FINE_LOCATION) || // api level 1
_requestedPermissionsArrayList.get(i).equals(Manifest.permission.ACCESS_COARSE_LOCATION) // api level 1
)
{
isFound = true;
ActivityCompat.requestPermissions(_activity, new String[]{
_requestedPermissionsArrayList.get(i)
}, ExConsts.MY_PERMISSIONS_REQUEST);
break;
}
}
现在，无论清单中的权限顺序如何，它都可以正常工作。干杯。您在清单上声明了权限并请求了运行时权限了吗？@Ragesh是的，这就是为什么它如此奇怪的原因。您可以发布您的日志吗？
