why android emulator not working - android

When I updated the Android Studio a few days ago, the Android Emulator stopped working. I tried to open a blank activity and the emulator did not work as well.
All the SDK tools have been installed and updated. Below are the event log and Logcat of a blank activity (Hello World!) when I run the blank activity.

I went to the Settings->Advanced in the Extented Controls in the emulator and then to Advanced and changed the OpenGL ES Render to SwiftShader and the OpenGL ES API level to Compatibility (OpenGL ES 1.1/2.0) and the errors appear to have gone away and the screen is now not displaying a white screen and is instead is displaying the google map, which is what the program is supposed to do. Does this seem like a good solution? Is there more I should do to not get screwed up in the future?

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

Androis studio - APP aborting shortly after starting [duplicate]

This question already has answers here:
What is a NullPointerException, and how do I fix it?

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:

Your setting dismiss() on your progress bar somewhere in your code with out having initialised it.
do
if(progress!= null)
progress.dismiss()
First, put only your application's log.
Second, you are trying to dismiss a progress dialog when its not initialized.
java.lang.NullPointerException: Attempt to invoke virtual
method 'void android.app.ProgressDialog.dismiss()' on a null object reference
I'd start my inspections with MainActivity.java:161

How to properly change UI theme?

I want a dark colored theme.
I changed the following in styles.xml:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
to
<style name="AppTheme" parent="android:Theme.Black">
and I also tried many other strings which either don't compile or cause the same crash.
Android monitor shows:

The theme of an AppCompatActivity (not Activity) must be an descendant of an Theme.AppCompat.
So check if your activity extends AppCompatActivity or not.
If so, change it extends Activity, or make your own theme which inherits from Theme.AppCompat and apply to your activity
