Android Studio — App not showing up/launching on Android Emulator

I am rather new to Android Studio and needed help as my app couldn't launch in the emulator despite following all the solutions I can find based on others' experiences.
I have 2 activities currently — Main and Login. I will post the AndroidManifest.xml below. Thank you all for the help and time in advanced!! (I also have this message in my event log: Can't bind to local 8700 for debugger)
<?xml version="1.0" encoding="utf-8"?>
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher_round"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity
android:name=".LoginActivity"
android:label="#string/title_activity_login">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<data
android:host="ID.firebaseapp.com"
android:scheme="https" />
<category android:name="android.intent.category.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".MainActivity">
</activity>
</application>

Solution:
Try this below code:
<activity
android:name=".MainActivity">
<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:host="ID.firebaseapp.com"
android:scheme="https" />
</intent-filter>
</activity>
<activity android:name=".LoginActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Try it ... Hope it helps.

<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher_round"

That maybe help you. :)

To test your app when using the Google Play services SDK, you must use either:
A compatible Android device that runs Android 2.3 or higher and includes Google Play Store.
The Android emulator with an AVD that runs the Google APIs platform based on Android 4.2.2 or higher.

Launch activity when google.com opened in browser

I am trying to launch my activity when google.com is navigated to in the browser, but it is not working. Here is my manifest:
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.example.myapp.MainActivity"

Anyone see what's wrong?

So, apsolutely no permissions in my manifest file, and I still get the Phone calls permission. I DON'T GET IT!

The compiler automatically adds this permission for compatibility reasons if your app use a library designed to run on Android 1.5 or below (because this permission was introduced in Android 1.6).
I guess it's caused by the AdMob library, which still supports Android 1.5.

My app doesn't show on emulator, when I run the project

when I try to run the project it installs successfully on an emulator, but emulator does not show my app launcher icon in its app menu. but however it shows my app in installed apps in setting>applications>manage applications>all apps , so that means that an app was installed. but it didn't run.

Make sure your starting activity has its intent-filter declared properly in your manifest to be shown in the launcher.
Assuming you want "Splash" to be your main activity change its declaration to this (specifically the intent-filter action)
<activity
android:name=".Splash"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Your intent filter action was not part of the android defaults (and what launchers normally look for). Only launchers that were designed to look for the action "com.thenewboston.travis.SPLASH" would see your activity

<activity
android:name=".Splash"
android:label="#string/app_name" >
<intent-filter>
<action android:name="com.thenewboston.travis.SPLASH" /> //try "android.intent.action.MAIN" here//
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
