Issue with adding ROLE_ASSISTANT

Now that Android 10 & above has this feature, I'm trying to add it. Included this in the manifest:
<action android:name="android.intent.action.ASSIST"/>
And here's the code:
mRM = (RoleManager) mAppContext.getSystemService(Context.ROLE_SERVICE);
bAvailable = mRM.isRoleAvailable(RoleManager.ROLE_ASSISTANT);
if (bAvailable) {
roleIntent = mRM.createRequestRoleIntent(RoleManager.ROLE_ASSISTANT);
startActivityForResult (roleIntent, REQUEST_CODE);
}
But, I keep getting this error:
RequestRoleActivity: Role is not requestable: android.app.role.ASSISTANT
RequestRoleFragment: Role request result requestingUid=10021 requestingPackageName=com.broadcom.BcmMicCapture roleName=android.app.role.ASSISTANT qualifyingCount=-1 currentUid=-1 currentPackageName=null grantedAnotherUid=-1 grantedAnotherPackageName=null result=1
Any idea what's amiss here? Is it a sepolicy issue? Or the app needs to add some other permissions?

Unfortunately this is not possible anymore.
Google made this role not requestable:

Azure Authentication with AAD & Google in a Xamarin Forms Project not Redirecting back to app after Authorized

Azure Active Directory
Google+ Auth
Xamarin Forms, PCL (NuGet 2.4.0.282)
Microsoft.Azure.Mobile.Client 4.0.0 & 4.0.2
After I successfully Login my phone does not return to my app. I have two test phones and one emulator, they display different info, after login.
Phone 1 (AAD Auth):
Phone 1 (Google Auth it greys out and just keeps "loading")
Phone 2 (AAD and Google Auth):
Emulator (AAD and Google Auth):
I have done everything I found here on Stack OverFlow, that makes sense and seems to be applicable to current versions of NuGets.
This person seems to be having a similar issue to me but with Google Log in
Azure not redirecting after loginenter link description here
I have tried integrating code into my project. And then I input my Azure info into Xamarin's sample: https://github.com/xamarin/xamarin-forms-samples/tree/master/WebServices/TodoAzureAuth
And I get the same results. I have tried both AAD and Google+ Auth. After login it just stays at the browser. So I feel like the client side code has to be correct. But I cant find any mess up on my Azure server code. I have tried this with projects that have a C# and Node.Js backend.(For one of my projects) My ALLOWED EXTERNAL REDIRECT URLS is ToDoList53172://easyauth.callback and in my AndroidManifest.xml looks like this:
<?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.xamarin.sample.TodoAzure">
<uses-sdk android:minSdkVersion="15" />
<application android:label="TodoAzure" android:icon="#drawable/icon">
<activity android:name="com.microsoft.windowsazure.mobileservices.authentication.RedirectUrlActivity" android:launchMode="singleTop" android:noHistory="true">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="ToDoList53172" android:host="easyauth.callback" />
</intent-filter>
</activity>
</application>
</manifest>
OLD:
And I don't feel like I should post all the other code. It is all in the Xamarin sample project posted above. If people think I should I will.
NEW:
I am adding more code just to help people out. I did not want to overload, but better to have all the info in one place. So here is my MainActivity.cs Code
using System;
using System.Threading.Tasks;
using Android.App;
using Android.Content.PM;
using Android.OS;
using Microsoft.WindowsAzure.MobileServices;
using Android.Webkit;
namespace TodoAzure.Droid
{
[Activity(Label = "TodoAzure.Droid",
Icon = "#drawable/icon",
MainLauncher = true,
ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation,
Theme = "#android:style/Theme.Holo.Light")]
public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsApplicationActivity, IAuthenticate
{
MobileServiceUser user;
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
global::Xamarin.Forms.Forms.Init(this, bundle);
Microsoft.WindowsAzure.MobileServices.CurrentPlatform.Init();
App.Init((IAuthenticate)this);
LoadApplication(new App());
}
public async Task<bool> AuthenticateAsync()
{
bool success = false;
try
{
if (user == null)
{
// The authentication provider could also be Facebook, Twitter, or Microsoft
user = await TodoItemManager.DefaultManager.CurrentClient.LoginAsync(this, MobileServiceAuthenticationProvider.Google, Constants.URLScheme);
if (user != null)
{
CreateAndShowDialog(string.Format("You are now logged in - {0}", user.UserId), "Logged in!");
}
}
success = true;
}
catch (Exception ex)
{
CreateAndShowDialog(ex.Message, "Authentication failed");
}
return success;
}
public async Task<bool> LogoutAsync()
{
bool success = false;
try
{
if (user != null)
{
CookieManager.Instance.RemoveAllCookie();
await TodoItemManager.DefaultManager.CurrentClient.LogoutAsync();
CreateAndShowDialog(string.Format("You are now logged out - {0}", user.UserId), "Logged out!");
}
user = null;
success = true;
}
catch (Exception ex)
{
CreateAndShowDialog(ex.Message, "Logout failed");
}
return success;
}
void CreateAndShowDialog(string message, string title)
{
var builder = new AlertDialog.Builder(this);
builder.SetMessage(message);
builder.SetTitle(title);
builder.SetNeutralButton("OK", (sender, args) => { });
builder.Create().Show();
}
}
}
And Like I said above I have tried this with AAD as well. The code above is for Google.
Here is my Azure Auth setup
Here is the info I get after logging in with "https://todolistjbb.azurewebsites.net/.auth/login/aad" and then visiting
"https://todolistjbb.azurewebsites.net/.auth/me"
I feel like I have tried SO many things. I have recorded 66.68 hours working on just trying to get Authentication in my app.... please... someone tell me what I am doing wrong! I am losing it over here :'(

The way to solve this problem is do not start with a capitalized letter for your Url Scheme. It took me over 2 weeks to figure it out. I don't think this sis written anywhere, but I am sure it is.
So yeah to fix this i switched "ToDoList53172" to "todolist53172"
That's it... Oy vey!

According to your description, I assumed that you are using the Server-managed authentication provided by Azure App Service authentication/authorization. Since you are using the Microsoft.Azure.Mobile.Client >= 4.0.0, for your mobile client, you would leverage the following code snippet for logging via the server-flow:
var user = await client.LoginAsync(this, provider, "{url_scheme_of_your_app}");
Details you could follow Add authentication to the app. Moreover, you need to Add your app to the Allowed External Redirect URLs.
Based on the error message from your phone 2:
todolistjbbservice://easyauth.callback/#authorization_code=xxxxx
It seems that you did not configured the Authorized Redirect URI correctly. For the Azure Active Directory provider, you could follow here for registering your Web App / API or Native application. For the Google provider, you could follow here.
After correctly configured your preferred identity provider(s), you need to add your app to the Allowed External Redirect URLs:
Log into Azure Portal, choose your App Service
Click the Authentication / Authorization,
enter ToDoList53172://easyauth.callback in the Allowed External Redirect URLs, and save your changes.

Push notification reaching ios (apns) but not android (gcm) device

So I have a simple Ruby app that uses Rpush to send push notifications to my iphone and my android phone. Right now all it does is sends it to the iphone. I am not sure whether the problem is with my script (i.e. incorrect values for the registration_id, app_name, or auth_key), or whether the problem is how I have my Android app configured.
The relevant part of that code is here (values changed for security - but format/length of keys left untouched to make sure they "look right" to people with experience)
API SETUP/RATIONALE (Sending the notification)
# GCM
app = Rpush::Gcm::App.new
app.name = "MyApp"
app.auth_key = "POfaSyfghilK3l-ueSvRLmbawcRThCWkwmcYGeM"
app.connections = 1
app.save
n = Rpush::Gcm::Notification.new
n.app = Rpush::Gcm::App.find_by_name("MyApp")
n.registration_ids = ["derGV80JK-s:APA91bHgerskBnrhHndes947nMKxI116tC3-k-tGd-hT5NzVc8QAWEkvCrMwrvs78RUL8-vvhp2ultoevqzZnn8gsr9t6WDXDYpGfCliqaJzj0XByBgbi0bm-rYufjcxfCc_5lEL381F"]
n.data = { message: "testing!" }
n.save!
Rpush.push
I determined that the name of my app was "MyApp" by looking at my google developer console here and noticing that the "Project Name" of the desired project is "MyApp".
I determined the Auth Key on the same site, by navigating to API & Auth -> Credentials -> API Key and copy/pasting the API key from there.
I determined my device's registration id using this code in the main activity of my Android App:
public static String getDeviceID(Context context) {
final TelephonyManager tm = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
final String tmDevice, tmSerial, tmPhone, androidId;
tmDevice = "" + tm.getDeviceId();
tmSerial = "";// + tm.getSimSerialNumber();
androidId = ""
+ android.provider.Settings.Secure.getString(
context.getContentResolver(),
android.provider.Settings.Secure.ANDROID_ID);
UUID deviceUuid = new UUID(androidId.hashCode(),
((long) tmDevice.hashCode() << 32) | tmSerial.hashCode());
String deviceId = deviceUuid.toString();
return deviceId;
}
When logged, getDeviceID shows me the registration id that I specified in the above ruby code.
APP SETUP/RATIONALE (Receiving the notification)
First, I set up my Android Manifest to have all the necessary permissions
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="com.johncorser.myapp.permission.RECEIVE" />
<permission android:protectionLevel="signature"
android:name="com.johncorser.myapp.permission.C2D_MESSAGE" />
<uses-permission android:name="com.johncorser.myapp.permission.C2D_MESSAGE" />
Then, I set up a listener service to react to push notifications:
<service
android:name="com.johncorser.myapp.services.GcmListenerService"
android:exported="false" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
</intent-filter>
</service>
That class is very simple and looks like this:
public class GcmListenerService extends com.google.android.gms.gcm.GcmListenerService {
public void onMessageReceived(String from, Bundle data) {
String message = data.getString("message");
Log.d("push", "From: " + from);
Log.d("push", "Message: " + message);
}
}
I would expect these messages to log out after sending the push notifications. But instead nothing happens (no exceptions thrown on the server or app).
Any one see what I'm doing wrong here?

Why are you using the UUID you generated from the Android Device ID as a registration ID for Google Cloud Messaging?
That's NOT how you get a registration id.
To get a registration ID you have to register with GCM on the device and receive back a registration ID/token, as described in Cloud Messaging for Android Quickstart:
InstanceID instanceID = InstanceID.getInstance(this);
String token = instanceID.getToken(getString(R.string.gcm_defaultSenderId),
GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);
In order for the above code to work you need to have a google-services.json configuration file (which is parsed by the com.google.gms.google-services gradle plugin, that you also need) in your app/ directory and you need the gcm_defaultSenderId which is the Project ID (Number) you get from the Google Developers Console.
You can easily generate that file and receive the above details by clicking the button "Get a configuration file" and following the steps mentioned there.
The code to get the registration ID needs to be in an IntentService as described here, and you need to define the service in the AndroidManifest.xml file as outlined here
For GCM to be able to communicate with your app, you also need to define in the manifest file a com.google.android.gms.gcm.GcmReceiver which has an intent filter with an action name "com.google.android.c2dm.intent.RECEIVE" and a category name with your package name. Look here for an example.

Try running the sample here by Google themselves.
https://developers.google.com/cloud-messaging/android/start
https://github.com/googlesamples/google-services/tree/master/android/gcm
I feel like something might just be missing in your manifest file.
Hope that helps.

In case anyone else runs in to this, the problem was that I did not whitelist my IP address on developers.google.com. I now have it set so all IPs are whitelisted, and it works like a charm.

ACRA : Configured to send report on mail but not getting any mail

I am trying to configure ACRA for the first time. I have followed the Basic Setup guide :
1.Integrated the acra jar file to my app
2.Created a new class extending application class and have added the below code to it :
#ReportsCrashes(formKey = "", // will not be used
mailTo = "mymailId#gmail.com")
public class MyApplication extends Application
{
#Override
public void onCreate()
{
super.onCreate();
ACRA.init(this);
}
}
3.Made all necessary changes to manifest file
It seems that all is done correctly,I am able to get the below in logcat :
12-21 14:59:10.994: D/ACRA(28728): ACRA is enabled for com.android.demo.notepad1, intializing...
12-21 14:59:11.064: D/ACRA(28728): Using default Mail Report Fields
12-21 14:59:11.064: D/ACRA(28728): Looking for error files in /data/data/com.android.demo.notepad1/files
12-21 14:59:11.074: W/ACRA(28728): **com.android.demo.notepad1 reports will be sent by email (if accepted by user).**
But I am not able to get any mail :( !

As far i know, the mailTo option needs the user in order to send the email.
When an error occurs another mail client (such as Gmail.apk) has to be open to process the crash report and send e-mail. So the error will open a mail client and we need the user to click on send button.

Although a bit late, someone might find it useful anyways...
I did have at least a similar problem with ACRA 4.5.0 which I was able to resolve once all the other configuration options were actually set. This means – although partially labeled as optional – I had to give a value to the following options (in the #ReportsCrashes annotation)
resDialogText = R.string.crash_dialog_text, // Text to display upon crash
resDialogIcon = android.R.drawable.ic_dialog_info, //optional (apparently not). default is a warning sign
resDialogTitle = R.string.crash_dialog_title, // optional (apparently not). default is your application name
resDialogCommentPrompt = R.string.crash_dialog_comment_prompt, // optional (apparently not). when defined, adds a user text field input with this text resource as a label
resDialogOkToast = R.string.crash_dialog_ok_toast // optional (apparently not). displays a Toast message when the user accepts to send a report.
Though I had mode = ReportingInteractionMode.DIALOG, set which might be the source of my problems at least.

have not used "mailTo" field ,had only used #ReportsCrashes(formKey = "formkey")
Make sure you get the form key from google drive correctly
And on crash you will be getting the report on Google drive excel file
And also make sure you have added Internet permission and Added "MyApplication" in mainfeast
<manifest ...>
<application ... android:name="MyApplication">
...
</application>
<uses-permission android:name="android.permission.INTERNET">
</uses-permission>
</manifest>

Trying to add a gmail account programmaticaly in android but getting error "caller uid 10040 is different than the authenticator's uid"

There is an emial application in android that allows to add email account. How can I add a gmail account in that application programmatically?
I used this link Add account automatically but
got SecurityException "caller uid 10040 is different than the authenticator's uid".
I used that code with
Account account = new Account("my id#gmail.com", "com.example.addaccount.account");
Where "com.example.addaccount.account" is package name of my application, and I added authenticator.xml file in a folder named xml, with same package name android:accountType="com.example.addaccount.account".
But I am getting error "caller uid 10043 is different than the authenticator's uid". Can any one please tell me, what am I missing? I just added the xml file and wrote that code to add account, do I need to refer to that xml somehow?

This method return the android market gmail account
public String getAccount(){
String email=null;
Account[] accounts = AccountManager.get(this).getAccountsByType("com.google");
for (Account account : accounts) {
email=accounts[0].toString();
}
return email;
}
also add this in manifest.xml
<uses-permission android:name="android.permission.GET_ACCOUNTS"/>
