问题


I am currently stuck with this problem: Google Maps seems not to be loading at all. Please see the image below:

This is really driving me crazy. I already have done the following:

  1. Added my package name + SHA1 (debug keystore) + SHA1 (release keystore) to Google Developer's console.
  2. Maps SDK for Android is enabled. The API key has Android app restriction
  3. Added google-services.json to my app from Firebase console
  4. Added necessary permissions:
  5. Added API Key to the Manifest file - from Google Developer Console
  6. Added meta data for gms version

This is the code of my fragment:

import android.content.Context;
import android.content.pm.FeatureInfo;
import android.content.pm.PackageManager;
import android.support.v4.app.ActivityCompat;
import android.support.v4.app.Fragment;

        return fragment;
    }

    public MapsActivity() {
    }

    @Override

    }

    @Override

        SupportMapFragment mapFragment = (SupportMapFragment) this.getChildFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);

    @Override

        LatLng augsburg = new LatLng(48.348527, 10.915952);

            // for ActivityCompat#requestPermissions for more details.
            return;
        }
        googleMap.setMyLocationEnabled(true);
        googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(augsburg, 13));

        googleMap.addMarker(new MarkerOptions()
                .title("Augsburg Zoo")
                .snippet("Der coolste Zoo der Welt")
                .position(augsburg));
    }
}

And this is the code for my layout:

<?xml version="1.0" encoding="utf-8"?>

        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

    <TextView
        android:id="@+id/textView15"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        android:text="Coming soon!"
        android:textColor="@color/colorPrimary"
        android:textSize="30sp"
        android:visibility="invisible" />
</RelativeLayout>

Can anyone tell what still I'm missing?

Please note that when I use the same API_KEY to other map projects, it is perfectly working. It seems that the map is not showing on my app but working on other projects.

These are my dependecies:

I had this problem yesterday in designing a customer in the company. it was two crazy days to work it out with the customer behind me. What I did was:

  1. Delete the current key (API Key) from the Google Dashboard APIs. Delete the firebase web key from the Google dashboard APIs. Create a new Key API for android, register the SHA-1 and package name. and add in project android studio;

  2. In the FIrebase project delete the SHA-1 code to add again. Download google-services.json, and add in the project;

  3. Generate the app in release mode, publish in the store, and download on some device, when running the app should show the Map normally;

  4. If not, it will show you the error in LogCat, saying that you must register the following SHA-1 key: XXXXXXXXXXXXXXXXX and the package name: com.your.packagename;

  5. Just register this key in Google APIs, and it will work in a few seconds, without even having to update the app in the store.

NOTE: Another thing, consider upgrading the dependencies of Google Maps, and Google Services.

Hope this helps.

I am assuming that this may due to mismatch SHA 1 Fingerprint. Double check that you are using the same keystore for getting SHA1.

or Let's check your API key is valid or not. For that add following MAP_API as your key

AIzaSyDztCvpv3PVBxzWwY7mWqCMnGfDeOiGxwY

add key directly to manifest

<meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="AIzaSyDztCvpv3PVBxzWwY7mWqCMnGfDeOiGxwY" />

Add following permission in your AndroidManifest.xml (Optional/not necessary)

 <permission
    android:name="your_pakage_name.permission.MAPS_RECEIVE"
    android:protectionLevel="signature" />

Build your apk. And test it.

If the map is showing then we can fix that your API key is the problem.

Otherwise

Maybe due to child fragment manager, So Initialize your fragment in view pager like below. then test it

 <fragment xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/map"
    android:name="yourpackage.MapsActivity"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" />

Have you tried these methods?

Enable Multidex:

https://stackoverflow.com/a/42827484/9169701

https://developer.android.com/studio/build/multidex

Note: If your project is configured for multidex with minSdkVersion 20 or lower, and you deploy to target devices running Android 4.4 (API level 20) or lower, Android Studio disables Instant Run.

Disable Instant Run:

回答4:


try adding this piece of Code in your onMapReady method

MapsInitializer.initialize(Objects.requireNonNull(getContext()));
googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
googleMap.setMyLocationEnabled(true);
googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(augsburg, 13));
googleMap.addMarker(new MarkerOptions()
            .title("Augsburg Zoo")
            .snippet("Der coolste Zoo der Welt")
            .position(augsburg));



回答5:


As you are using map in a fragment change your code like below:-

  // Obtain the SupportMapFragment and get notified when the map is ready to be used.
    SupportMapFragment mMapFragment = SupportMapFragment.newInstance();

    FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
    transaction.add(R.id.mapContainer, mMapFragment).commit();
    mMapFragment.getMapAsync(this);

Change the fragment tag in layout to FrameLayout like below:-

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/constraintLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <FrameLayout 
      android:id="@+id/mapContainer"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
    />


    .....
</RelativeLayout>

Upgrade your map sdk:-

implementation 'com.google.android.gms:play-services-maps:16.0.0'



回答6:


A few things to note.

  1. Checking runtime permissions (details) - your logcat says permission denied on one of the lines
  2. Try uploading the app to playstore in alfa or beta testing channel (to prevent access to targeted users before app passes all the tests.) - some APIs does not work unless your app is registered.

  3. If still the problem persists, try deleting and re-registering your app in firebase.

  4. Also, please note that google maps APIs are no longer available for free as before. You need to subscribe. Follow this link for more info. Hope this helps.

Solution:

 I had the same problem in my App so you can try this open your Android studio and
 make sure you are login with the same user id of what you had created 
 `console.developer` account and after that you should do 



 SupportMapFragment mapFragment;
 GoogleMap mMap;
 Marker marker;
 LatLng origin = new LatLng(30.5595, 22.9375);
 LatLng dest = new LatLng(30.5595, 22.9375);

  @Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;
    googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
    googleMap.addMarker(new MarkerOptions()
            .position(origin)
            .title("title")
            .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_BLUE)));

    googleMap.addMarker(new MarkerOptions()
            .position(dest));

    googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(origin, 15));
}




回答8:


I had this problem. In my case, I changed the API key and everything started working correctly. Check the logcat for the issue. If it is the same problem then change the key and it should work.
