I'm trying to implement the MediaPlugin but I am running into a problem. I have done all steps in the setup instructions and get the following error:
Error: No resource found that matches the given name (at 'resource' with value '#xml/file_paths')
As explained in the setup instructions - in my Android project, I have added a folder inside the Resources-folder, called xml - containing a file called file_paths.xml with the following contents:
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-files-path name="my_images" path="Pictures" />
<external-files-path name="my_movies" path="Movies" />
</paths>
I expect this problem to be related to either the above or the AndroidManifest.xml, so I'll include my complete AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="1" android:versionName="1.0" package="com.company.Kvitt" android:installLocation="auto">
<uses-sdk android:minSdkVersion="15" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<application android:label="Kvitt.Android">
<provider android:name="android.support.v4.content.FileProvider"
android:authorities="com.company.Kvitt.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/file_paths"/>
</provider>
</application>
</manifest>
Any help or ideas on how to solve this error are really appreciated!
The res/xml directory should be in the same sub-folder as other Resources; drawable, layout, mipmap-XXX, etc...
Do a clean all / build all just as a double check
Double-check your xml path in the project: Resources/xml/file_paths.xml
After a build, check the build artifacts for the file in obj/Debug/android/res/xml
If the resource file is not in the build artifacts the likely cause is the build action is wrong
Check that the build action on the file is set to AndroidResource

I'm new to Xamarin and trying to get OneSignal push notifications working in Android. When running the emulator and I fire a push notification from OneSignal, it comes through successfully on the emulator. However, when I deploy the app via Play Store, and I have the app open, firing a push notification crashes the app with the following error:

Is this because the OneSignal library is not being included in the release? I've also seen mention of AndroidX or multi-dex issues. Here is the android manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="15" android:versionName="1.0" package="com.woodfordgroup.whybuycars" android:installLocation="auto">

And here are my android project properties (target version is 29):
I also wonder if something went wrong with the inclusion of various libraries while I was installing OneSignal from Nuget. Here is my list of project references:
Add this to the proguard file.
-keep class com.onesignal.** { *; }
Source: See oncky's comment on question.
I had exactly the same issue, I could receive notifications without crash if disabled R8 code shrinker in settings ( or adding <AndroidR8ExtraArguments>--no-tree-shaking</AndroidR8ExtraArguments> after the <AndroidLinkTool>r8</AndroidLinkTool> in android .csproject file).
It seems there's some issue with shrinker for onesignal broadcast receiver class

Im using an emulator with Android 6.0 API 23. I also tried with Android 8.1 API 27.
I tried to search a lot of solution but I found anything about it.
Thank's for your help !
Having a check with whether installing Xamarin.Android.Support.v4 NugetPackage :
In addition , to be sure the environment is no problem with Setting up the Android SDK for Xamarin.Android.
Every time I debug, it installs 3 apps. I don't have idea why.

As pointed out in the comments. You have probably copied the [Activity] attribute from somewhere and included MainLauncher = true in two other Activities.
Remove MainLauncher = true from those Activities and it should only show one launcher.

Can anyone help me?
I've got the same issue (in my case using App Center Push SDK).
The issue was solved by avoiding uppercase on first letter of application/package name.
The first thing I will try to modify uses-permission tag:
<permission android: name = "com.companyname.progettocomputergraphics.MAPS_RECEIVE" android: ProtectionLevel = "signature" />
In my case I had to use
<meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="AIzaSyBFdb7p_3FTSQWX-sfOniZmQrsBHnM0Bu.."/>
in manifest
I am trying to get admob to work in my Xamarin Android application but I get the following message when trying to display an add:
"You must have AdActivity declared in AndroidManifest.xml with configChanges"
I ave added the Xamarin google play service to my application.
I am set the java heap size to 1G and build with API level 14
I have googled the error message and most answerspoint to the manifest file that needs to include two entries. I have added the entries but still have the problem.
Any idea what I am doing wrong? Here is my Manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="1" android:installLocation="auto" android:versionName="1.0">
