GoogleMaps.LocationServices NuGet package says namespace could not be found

I am creating an android application using Xamarin on Visual Studio 2017. I am trying to use the NuGet package GoogleMaps.LocationServices using this guide (http://www.c-sharpcorner.com/blogs/find-latitude-and-longitude-using-c-sharp1). I have installed the package fine
But when I try to use the package on my code like the guide I following does I just get an error saying it can't find the namespace:
This means that I cannot create a GoogleLocationService() object which is what I need to do to create a Google Maps pin point using a list of location addresses.
Anyone got any idea why I'd be getting this error? Unsure if I just need to use a different namespace now as this guide was from 2013.

The GoogleMaps.LocationServices 1.2.1 NuGet package contains an assembly for .NET 4.0 and no other target frameworks. So it does not support Android projects. NuGet will not add a reference to the GoogleMaps.Gelocation assembly since it is in the lib/net40 directory so it not considered compatible.
Instead I would take a look at the Xamarin.GooglePlayServices.Location NuGet package.
Looking at the content of the NuGet package it has a content file GoogleMaps.LocationServices.readme.txt which seems to be why you can install it into a Android project. This GoogleMaps.LocationServices.readme.txt file is added to your project.
Ideally the NuGet package should have a readme.txt file in the root of the NuGet package and not add a file to the project. Such a readme.txt file would be automatically opened on installation by Visual Studio without the need to add anything to the project. Removing the content file would also prevent the NuGet package from being installed into an Android project, or any other unsupported project type.
The older GoogleMaps.LocationsServices 0.9.0 can be installed into an Android project but that seems to be because the NuGet package is not packaged correctly. The GoogleMaps.Gelocation assembly in this version of the NuGet package is in the lib directory and does not indicate any target framework so it is allowed in all project types, which does not seem to be correct.

It's hard to trace what a new signature of the methods are in 2017, but from my brief look if you change the version on a package to
0.9.0 and use namespace
using GoogleMaps.Geolocation;
The example should work.

Visual Studio 2017 - Xamarin - The file "obj\Debug\android\bin\packaged_resources" does not exist

I'm fighting with that issue for 2 days already and can't find any solution.
I have an Xamarin Android app in Visual Studio 2017 consisting of three projects:
Xamarin.Android project (main one)
Android-specific unit tests run on the device - project of type NUnit 3 Test Project (Android) created using NUnit Templates for Visual Studio
Platform-independent unit tests project (project of type Unit Test Project (.NET Framework))
Everything worked just fine until now. When I selected my main project as the Startup one, my app was deployed to the device/emulator. When I selected my Android-specific unit tests project, the test project was deployed and unit tests executed by nUnit Xamarin Runners on the device/emulator.
However few days ago I updated my Visual Studio 2017 with the newest available update and now, when trying to build this android-specific unit tests project I get the following error:
The file "obj\Debug\android\bin\packaged_resources" does not exist.
I've searched everywhere, including this and this SO topics. I also totally reinstalled Visual Studio 2017 and Xamarin with Android SDK included. Nothing helped. From what I read I suspect there is something wrong with the versions of Android SDK Build-tools I have installed. Here's what I have currently installed in SDK Manager:
As the other SO threads suggested, I tried uninstalling the newest Android SDK Build-tools (25.0.2) and installed version 23.0.3 (all my projects target Android 6.0), but it also doesn't help, I still have the same error.
Maybe it's worth adding that this issue may have started to happen when I tried to implement RecyclerView in my app reading this tutorial, where they suggested to install Android 7.1.1 (API 25) in SDK Manager. However I undoed my all changes after that and even reintalled VS2017 + Xamarin.
Do you have any other idea why this can be ? I'd really appreciate any help. Thanks!
EDIT 2017-04-09:
Egh, I removed VS2017, installed VS2015 with brand new Android SDK and still the same issue :(

I've finally found what was the issue. It wasn't related to any component from SDK Manager or VS version.
Following localization tutorial from developer.xamarin.com, I played a bit with Strings.xml in my Android project. I wanted to have my Activities Label taken from resources as well, so in the ActivityAttribute I defined:
[Activity(Label = "#string/peopleListTitle")]
and added this value in Strings.xml file:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<!-------Other resources values ----->
<string name="peopleListTitle">People List</string>
</resources>
In that case my build is failing with above-mentioned error:
The file "obj\Debug\android\bin\packaged_resources" does not exist
When I change ActivityAttribute to use a string directly:
[Activity(Label = "People List")]
the build is passing without any issues.
I managed to find a solution, but actually I don't know why it's not building when I try to use Label text defined in Strings.xml.
BTW, I managed to find what's the problem by setting build output verbosity to Diagnostic in Tools -> Options -> Projects and Solutions -> Build and Run which gives a detailed info why the build failed in the Output window.

I had the same problem. After removing the dash "-" sign from the image file name, the problem is solved. Bad error message! It should not be:
The file "obj\Debug\android\bin\packaged_resources" does not exist.
Writing an error message like this causing the Developer to think about something else while the problem is the illegal file name.

I had the same issue when I added a new image as a resource.
There was a '-' in the file name (Invalid resource name character). I renamed & removed that character and all good.
Resource name can only consist of 0-9,a-z or A-Z or combination of any.

I had the same problem, and i removed all image file name have "-" character. My problem solved

Another reason for this error is that you may have a float number as your version number. In my case I changed it to a integer and everything worked fine. (I found the error by switching the build output to Detailed)

Simply it worked.
In one case I copied and pasted previous working "packaged_resources"
in the bin folder.[the problem was it did not reflect the UI changes]
Other I opened the visual studio as
administrator.
Next changed the "Minimum target to Android" to lower
apis in the project properties windows.
I suggest not touching the code behind of the design. If you get this error simply pull some button from the tool bar into the design and visual studio will come to its consciousness that there is change in UI. Next click on save all so that it make necessary change in the designer file.

Mine was a different solution (and only half a day lost): I was having trouble getting Hockey app to match crashes against the correct version of the app and realised it uses VersionCode not VersionName so I change my code to "0.0.34" the same as the name. For some still unknown reason the app built and deployed to devices for about 3 days before I started getting this error The file "obj\Debug\android\bin\packaged_resources" does not exist. Setting it back to a numeric value fixed the problem.
I found the problem by looking back through my GIT logs and rebuild each push until I found the one that caused the problem.

It just because the Version Code,I set Code by '1.0',The file "obj\Debug\android\bin\packaged_resources" does not exist.;And I set it by '1',everything is ok.

Had the same error, the way I got over it was crank up the Android SDK manager and install all updates and remove any obsolete packages. This happened to me because I was targeting something newer which was not installed.

Check to see if there are any unused entries in resources.designer.cs if there are any manually remove those entries.
This will fix the issue.

After following several online suggestions - updating SDK, updating Xamarin etc - none of which worked for me.
Finally found that I had an activity for a Android provider to Alarm clock in my AndroidManifest file as below
<activity
android:name="com.njcommuter.droid/android.provider.AlarmClock"
android:label="AlarmClock"
.....
/>
Removing this line - and rebuilding worked fine without any errors and was able to deploy solution successfully.
Note : testing this by putting the line back, and I get same error again on rebuilding.
It can be linked to using any android provider which creates the package for it, not necessarily AlarmClock only.

This error is, somewhat of, a wrapper for what can be multiple reasons that that the file was not created. The key is to look in the detailed output and look for the underlying error causing the file creation failure.
In my case, I had corrupted icon.png files (generated right from from the VS xamarin nunit template, no less!). Once I put in valid png files, everything was built fine.

Another reason for this error, if that the android NDK (not android SDK) isn't right, change de version can resolve the problem: go to Tools/Options/Xamarin/android Configurator and change de folder, in my case I've three, the last one can't compile, but the second folder with version xx.r11c do it.

For me it was Target Android Version.I had it set to
but changing it to Compiling version(for me it was the latest platform) resolved the issue.

How do I find Google Play version?

When I am setting up gradle, I have to add something like:
compile 'com.google.android.gms:play-services:6.1+'
I don't like to use the +, so I can always know which version the project is being compiled with and so I can avoid some surprise bugs.
In order to find the Google Play version I have currently downloaded, I usually go to the library XML file which I can find something like: "6171000", which is the version as an integer.
Is it there a simpler way to figure out the version that I need to write on gradle?

cd into your module (eg: app) dir, and run gradle command line ..\gradlew -q dependencies --configuration compile. This will resolve the + , and show you exact version being used for your library. See below.
Or, if you use Android Studio, when you modify/edit the version (eg: simply delete/add + at the end), Android Studio will show a yellow-bulb action with Replace with specific version, click on it to automatically replace the + with exact version available.

Go to this site: http://gradleplease.appspot.com/#play-services
You can also search for any library (Ex. recyclerview). This will help you specify the library's latest version.

CordovaResourceApi import unresolved phonegap

I am using phonegap-2.9.0 with file plugin. When I build project for android platform it creates two packages within the src/ folder:
org.apache.cordova.file
org.apache.cordova.filetransfer
I get below errors within these two packages:
1 - org.apache.cordova.file.FileUtils
Method testSaveLocationExists() from the type DirectoryManager is not visible
Method getFreeDiskSpace() from the type DirectoryManager is not visible
Method testFileExists() from the type DirectoryManager is not visible
2 - org.apache.cordova.filetransfer.FileTransfer
import org.apache.cordova.CordovaResourceApi unresolved
import org.apache.cordova.CordovaResourceApi.OpenForReadResult unresolved
Could someone please tell me what I should do to resolve these?
Thanks.

You have two problems.
1) Version of Phonegap is outdated
2) The way to install a plugin is:
-> phonegap plugin add "urlofplugin" or "/path""
-> phonegap platform add android
-> phonegap prepare
-> phonegap build
sometimes the plugin has a different default installation, the files need to change the platform.

Well, I dont know if I can help you, but I had similar problems. When I installed exactly those two plugins I got an error too. A different one, which I dont perticularly remember, something to do with a missing file that I can easily find in the file manager. Anyway, what helped me was:
I updated to a more recent version, if you are able to I advice for it.
After installing the plugins through cordova cmd api (.nodejs command prompt ... you know what I mean) I was forgetting to build in the api itself. It sounds stupid but I was using wp8 and thus using a template for visual studio. The studio gave me the error, the building process (in cmd) also gave errors, but it was fixed by updating to the newer version.

You need to configure you build path and then add library from external source and select the library then it will resolve or u can make copy and paste cordova library .jar file in your lib folder. then it will remove, if not happen then tell me .......

I am not sure if that will work but first uninstall these plugins using phonegap/cordova CLI and than reinstall it in the root of application folder using the CLI only like this:
phonegap local plugin add <required plugin>
This worked for me after reinstallation.

Phonegap 2.1 for Android - Hello World App 3 errors at launch

I developed something with Phonegap for iOS, but this is my first trial for Android.
I created my hello world application with CLI sth like this mentioned here:
$ /path/to/cordova-android/bin/create /path/to/my_new_cordova_project com.example.cordova_project_name CordovaProjectName
Even though I created this app in Eclipse Workspace, I needed to import it to Eclipse. I created two AVDs. One for API level 8, one for API level 16.
When I try to build, it gives me these three errors and a warning. What is wrong with my setup?
Description Resource Path Location Type
error: No resource identifier found for attribute 'hardwareAccelerated' in package 'android' AndroidManifest.xml /com.example.test.testprojectname line 20 Android AAPT Problem
error: No resource identifier found for attribute 'xlargeScreens' in package 'android' AndroidManifest.xml /com.example.test.testprojectname line 22 Android AAPT Problem

Go to Project -> Properties -> Android and select a newer SDK (preferably the latest one), after that run Project -> Clean. That worked for me.

Check the minSdkVersion and targetSdkVersion attributes in your AndroidManifest.xml. It sounds like you're building the app for an older SDK version that didn't have the attributes that are producing the errors. Try to set both min and target to 11 and see what happens.

You should always be building for the latest SDK. It looks like your Eclipse setup is using an old version of Android (Android 2.2?). hardwareAccelerated and xlargeScreens is from Android 3.x. I recommend making sure your project uses the latest version fo the SDK in Eclipse. This has nothing to do with your Android Manifest, and is actually an eclipse setting.

By default android version is 2.1; you must right click on root folder of you project, select properties, then in android select new version; try to reload it and it wrok...

You should always be building for the latest SDK. It looks like your Eclipse setup is using an old version of Android (Android 2.2?). hardwareAccelerated and xlargeScreens is from Android 4.x. I recommend making sure your project uses the latest version of the SDK in Eclipse.
(or)
after creating your project Do the following steps
Right click your project -> properties --> change the Android target version as 4.x
