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->
04/23 23:13:41: Launching 'app' on Nexus 6 API 24.

public string Post([FromBody] TblUser value)
{
if (dbContext.TblUser.Any(user => user.UserName.Equals(value.UserName)))
{
TblUser user = dbContext.TblUser.Where(u => u.UserName.Equals(value.UserName)).First();
var client_post_hash_password = Convert.ToBase64String(
Common.SaltHashPassword(
Encoding.ASCII.GetBytes(value.Password),
Convert.FromBase64String(user.Salt)));
if (client_post_hash_password.Equals(user.Password))
return JsonConvert.SerializeObject(user);
else return JsonConvert.SerializeObject("Wrong Password");
}
else
{
return JsonConvert.SerializeObject("user does not exists in db");
}
}
}
}

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>

App crashes in Release mode due to Firebase dependency

I have an app that i've recently noticed crashes on devices that do not have Google Play Services installed. After a bit of debugging i've noticed the cause is Firebase.
This is fine with me because i figured Firebase needs Google Play Services to run.
The issue however is the sudden crash. I have tried detecting if Google Play Service is available first thing in the launcher activity so that i can show the user a proper message, but the app crashes immediately without even executing code in the launcher activity or in the Application class.
How can i properly handle this Firebase error. I need a proper way to catch the error or prevent it from occurring and display a proper message instead of a crash. I have looked at a lot of similar questions and tried the solutions out but this case looks a bit different.
Note, this ONLY happens when the app is in Release mode. Also, you will notice the logcat highlights SQLite, nowhere do i use SQLite in this project, i reckon maybe Firebase is referencing it.

I finally figured how to go about this.
FirebaseCrashlytics initializes even before the Application class is executed and therefore in release mode on a device without Google Play Service it instantly crashes. The best way to handle this properly is to disable FirebaseCrashlytics from immediately trying to collect any analytics data when running the app by disabling analytics collection in the Android Manifest:
<meta-data
android:name="firebase_analytics_collection_enabled"
android:value="false" />
Then in the Application class, we can check if Google Play Services is available. If so we can proceed to enable analytics by Firebase:
class MyApp : Application(){
override fun onCreate() {
super.onCreate()
if(isGooglePlayServicesAvailable()){
FirebaseCrashlytics.getInstance().setCrashlyticsCollectionEnabled(true)
}else{
//show user proper error
}
}
private fun isGooglePlayServicesAvailable(): Boolean {
val googleApiAvailability = GoogleApiAvailability.getInstance()
val status = googleApiAvailability.isGooglePlayServicesAvailable(this)
if (status != ConnectionResult.SUCCESS) {
return false
}
return true
}
}

React Native Android Project Failing on Hermes but "enableHermes: false"

I go to build > clean project, then build > build project, "react-native run-android" from root of react native project, metro terminal spins up, I click the green arrow 'run app' button on android studio, the app pops up loading on the emulator, then exits to emulator home screen, and this error is in the run tab log. Relatively new to react native, can't find anything that gives me a solution. Not sure what's happening or where to go from here. Any help is much appreciated

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

Facebook Audience Network not displaying test Ads. Already added TestDevice

I created a new sample project for displaying the Facebook audience network Banner ad at bottom of my activity.
My app is running in device but not displaying anything at bottom. I already added the hash for test device.
MainActivity.java
package liveradio.radioz.com.facebookads;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import com.facebook.ads.*;
import android.widget.LinearLayout;
public class MainActivity extends AppCompatActivity {
private AdView adView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
adView = new AdView(this, "PLACEMENT-ID", AdSize.BANNER_HEIGHT_50);
// Find the Ad Container
LinearLayout adContainer = (LinearLayout) findViewById(R.id.banner_container);
// Add the ad view to your activity layout
adContainer.addView(adView);
AdSettings.addTestDevice("DEVICE-ID");
// Request an ad
adView.loadAd();
}
#Override
protected void onDestroy() {
if (adView != null) {
adView.destroy();
}
super.onDestroy();
}
}

I'm getting the build successful and installed in my device. When I open the app I can't see any ads or test ads at bottom of my main activity.

If you've added Audience network libraries, you can add the code below to show test ads without worrying about adding a test device.
if (BuildConfig.DEBUG) {
AdSettings.setTestMode(true);
}
Add this code, preferably in your Application class.

First Implement this library:
implementation 'com.facebook.android:audience-network-sdk:4.99.1'
than use below code:
com.facebook.ads.AdView adView;
adView = new com.facebook.ads.AdView(this, "PLACEMENT-ID",
com.facebook.ads.AdSize.BANNER_HEIGHT_50);
((LinearLayout) adContainer).addView(adView);
adView.loadAd();

first, add this library to your grade file
implementation 'com.facebook.android:audience-network-sdk:6.12.0'
then paste this code in your xml file
<LinearLayout
android:id="#+id/banner_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:orientation="vertical"
/>
In your Java code paste this code and also replace IMG_16_9_APP_INSTALL#YOUR_PLACEMENT_ID with your banner ad ID
adView = new AdView(this, "IMG_16_9_APP_INSTALL#YOUR_PLACEMENT_ID", AdSize.BANNER_HEIGHT_50);
LinearLayout adContainer = (LinearLayout) findViewById(R.id.banner_container);
adContainer.addView(adView);
adView.loadAd();
