Using O Auth for google api on android app

What should i add here for the scheme for URl redirect, can i add anything, like "com.example.oauth/:oauth2redirect"(Package name:/ oauth2redirect)?.
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.oauth">
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.INTERNET">
</uses-permission>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/Theme.Oauth">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<data android:scheme=" ">
</data>
</intent-filter>

The most common option when learning Mobile OAuth is to start with a value like this, using a reverse DNS style of naming, to include your company + app names:
com.mycompany.myapp:/callback
A good starting point for something to compare against is the Android AppAuth Code Sample, where you just specify a scheme value in the gradle file.
If it helps, my Blog Post has some step by step instructions to get the sample running.

"Default activity not found"

I keep getting the "Default activity is not found" error whenever I want to try and run my app. I have tried 'clean project', 'invalidate caches/restart' and restarted my computer.
UPDATE: I tried running different projects, but they all give the same error too. This makes me think there must be something wrong with settings.
It works perfectly for my friend, but I get the error that the "Default activity is not found". If I try to launch a specific activity it also says the activity is not found. This is the code in the androidmanifest.xml file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

The API key for Google Maps-based APIs is defined as a string resource.
(See the file "res/values/google_maps_api.xml").
Note that the API key is linked to the encryption key used to sign the APK.
You need a different API key for each encryption key, including the release key that is used to
sign the APK for publishing.
You can define the keys for the debug and release targets in src/debug/ and src/release/.

<activity
android:name=".GoogleMaps"
android:label="#string/title_activity_google_maps" >
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="#string/google_maps_key" />
</activity>
<activity android:name=".Profile" />
</application>
</manifest>

If it works for your friend and it is the same code it could be that all you need to do is to refresh the cache of your IDE:
File -> Invalidate Caches / Restart

Try this::
Your manifest is missing default activity
Add to any activity as you consider a default activity
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>

I finally solved it by making sure all implementation versions were the same, there were some in a 28.0.0 version and others in a 26.1.0. version. Now the app works fine on the emulator. Thanks for your suggestions though

<uses permission> in android studio is not working / application is not asking for permission

I am trying to make an app which starts by asking permission and accesses the hotspot of any device and any android version with which the very first problem which is bothering me is that why is not working, i have tried it on two devices and both of the attempts were unsuccessful.Please can anyone help me out to point my mistake. I checked similar questions related to it and have tried correcting it too but still not working..
here is the xml code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.akshay.turnonhotspot2">
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

It is changed since Android API 23.
You also have to ask permissions at Runtime.
Check this document

Permissions are asked when when you need user personal data such as contacts, storage(photo, video, file) and etc..
You don't need to ask permission for android.permission.INTERNET, android.permission.ACCESS_NETWORK_STATE, android.permission.ACCESS_WIFI_STATE, android.permission.CHANGE_WIFI_STATE

Flurry integration Android throwing errors

I'm trying to integrate flurry into my android app. I'm using the recommended setting and have repositories{jcenter()} and
// Required for Flurry Analytics integration
compile 'com.flurry.android:analytics:8.2.0#aar'
// Optional - If you want to use the Ads SDK
compile 'com.flurry.android:ads:8.2.0#aar'
in the gradle as the docs suggest. I keep getting errors in the that Application is not resolved. The docs really blow and I'm not 100% sure what going on. I've never integrated flurry before can someone please help! I put the manifest and the class i'm using below. I know it doesn't have a key I'm still working on removing errors. I'm dumping the that class in the main file for simplicity for now.
<?xml version="1.0" encoding="utf-8"?>

PLACES_API_KEY_INVALID shown but everything seems to be done right

My app uses the Google Places API to function however when I use the line placeLikelihoods.getStatus().getStatusMessage() , I get the message PLACES_API_KEY_INVALID. I've been googling for days and can't find a solution. When I go to https://console.developers.google.com/apis/credentials?project=myprojectdebug and click on my project, I am redirected to a page that shows my API key, the date I made it and my email used to make it.
This is my manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="censored b/c its got some private stuff in name">
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

android:value="#integer/google_play_services_version" />
<meta-deta
android:name="com.google.android.geo.API_KEY"
android:value="My 39 character API key is here" />
</application>
What am I doing wrong? I feel like giving up but I also want to know what's wrong
EDIT: Found the problem however I can't fix it. I didn't use the proper keytool command shown here https://support.google.com/googleapi/answer/6158862 but when I run this command it gives me an error because my account name has a space between my first and last name thanks to me using a microsoft account.

Ok, i got your error. You misspell meta-data. Check your tag, you wrote 'meta-deta'

check this one in your manifest file i placed
android:name="com.google.android.maps.v2.API_KEY"
instead of this (place below one and check spelling)
android:name="com.google.android.geo.API_KEY"
in your AndroidManifest.xml file like
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="#string/api_key"/>

1) Have you enable/activate google place api?
2) Did you keep switching your workstation? If you run your code using another pc (not the original one you use to generate api key), you need to request new API key because the debug key has changed.
