App crashes in the android studio emulator in maps activity

I have created a google map activity in android studio. I have also generated an api key from the link given and placed it in the appropriate place. But when I run the app it crashes without displaying anything. Here is the logcat

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

Google Maps Fragment View not rendering content

I have an android studio project where I am using a map view fragment. In my old project, it worked well and displayed a map, but in my new one, the map is just blank (grey). Even the google logo is missing on the map.
Here is my logcat error log:

Any idea what is going wrong with my MapView?
if you need more info or code, please write me.
Thanks.

You need to check if the Google Maps Android API is enabled in your Developer's Console. If it is, check if you put the Android API Key in the google_maps_api.xml

go to https://console.cloud.google.com/apis/credentials
update Application restrictions with used domains and API restrictions with used API.
the changes takes more than 5 mins to reflect

AdView Causing Chrome Crash?

I have an adview in one of my activitites. When I go to this activity, I get a dialog on the emulator telling me Chrome has stopped and the ad doesn't show anything.
I've checked over the code itself and I'm fairly sure it matches what it should -
Activity.xml
<com.google.android.gms.ads.AdView
android:id="#+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
ads:adSize="BANNER"
ads:adUnitId="#string/banner_ad_unit_id"></com.google.android.gms.ads.AdView>
Activity.java
mAdView = (AdView) findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
mAdView.loadAd(adRequest);
Here is the logcat -

On my Pixel XL, it doesn't crash, but no ad is shown, so I guess something isn't right?

We had the same crash in our app. A temporary solution was to disable the use of the preloaded_fonts tag in AndroidManifest.xml.

There appears to be a bug in Android 8.0 Oreo at present as this does not happen in earlier API's.

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.

if(progress!= null)
progress.dismiss()
