Why Android Volley library is unable to connect asp.net web api?

I am trying to call asp.net web api from Android Client using Volley library. The .net API is working fine and listening ports are:
http://localhost:5000 and https://localhost:5001 in my local machine.
But,When, I try to run android client keeping the base url as http://10.0.2.2:5000/api/login
I found below error in console->

Try this
1.In Android Manifiest, in tag application add:
inside tag application add this tag:
<uses-library android:name="org.apache.http.legacy" android:required="false"/>
<application
android:usesCleartextTraffic="true"
android:networkSecurityConfig="#xml/network_security_config"
...
/>
2.With a corresponding network_security_config.xml in app/src/main/res/xml/:
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<base-config cleartextTrafficPermitted="true" />
</network-security-config>

This is the compelte log.I have even tried by removing the restrictions but that didn't work. Whats the issue here. I have also seledted api 23 marshmallow. I have done nothing except entering the api key in its place
EDIT: I also included the key in the manifest but still the app is crashing
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="YOUR_API_KEY"/>

EDIT:
Seems to be an issue in API 28
To fix it add this code under application in your manifest file:
<uses-library android:name="org.apache.http.legacy" android:required="false"/>
Its probably because you dont have google play services installed. If you ran the app on your actual phone it would work just fine.

To fix it, you either add this line of code inside the in the manifest
<uses-library android:name="org.apache.http.legacy" android:required="false"/>
Or
to upgrade your play-services-maps in build.gradle to
implementation 'com.google.android.gms:play-services-maps:16.1.0'
That worked for me

ClassLoader referenced unknown path /data/app/.../1/lib/arm64

I am concerned what the System warning in my android app means.
ch.ethz.inf.vs.a4.minker.einz W/System: ClassLoader referenced unknown path: /data/app/ch.ethz.inf.vs.a4.minker.einz-1/lib/arm64
This warning comes up when I run the app and then don't do anything - just displaying the main Activity. The app does not crash, but I'd like to know why these warnings are showing up.
This is the complete logcat when I run the application on my Sony Xperia device, but the Emulator creates similar logs.

This answer mentioned disabling instantRun, which I have already done because of my version of IntelliJ not supporting the latest version of gradle yet (last time I checked with support). It also mentions WiFi, but that doesn't seem to make a difference.
This answer mentions clearing app cache and data, but this also does not make a difference.
It might be worth mentioning that the first time I run the app, IntelliJ shows the following error in the logcat. This happens both on the emulator and my real device. With "the first time", I mean that it does not show the error when I click run again and select "restart app". This behaviour is not 100% consistent though.

What could be reasons for these warnings? I am afraid that if I ignore them, I will at some point spend days debugging only to find out that these warnings would have told me.

you need to set the flag of intent.
Intent intent = new Intent(context,Route.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);

Androis studio - APP aborting shortly after starting [duplicate]

This question already has answers here:
What is a NullPointerException, and how do I fix it?
(12 answers)
Closed 5 years ago.
I just finished a project in android studio and I have a problem here. When generating the application and installing on the smartphone (android nougat 7.1.1 oneplus3) it simply aborts. In the emulator it gives the message that the application stops and aborts. I need the help of you more experienced. I'm a beginner. Here's the LOGCAT lines below when you try to open the application:

The problem is that app gets crashed twice within few minutes of running it and besides Application terminated. and normal logs no error is shown in the logcat.

Application terminated.
I tried integrating crashlytics but even it doesn't show any error when the app crashes in this manner.
The question is how will I be able to fix the error if I don't even know what the error is?
Please help me with this.

I think the issue is related to your ad view.
In last line it is showing that ad is not visible.
