Map Fragment not working in Android

Question

I've already tried a thousand configurations and codes, but my map activity insists in not working. Things I've tried:

AndroidManifest.xml

• enabled access permissions (INTERNET, ACCESS_FINE_LOCATION, READ_GSERVICES etc);
• enabled OpenGL (android:glEsVersion="0x00020000" etc);
• supplied two keys (com.google.android.geo.API_KEY and com.google.android.maps.v2.API_KEY) with directly key in AndroidManifest and referencing that by xml values in debug and release folders (@string/map_api);
• tried to use map library (uses-library android:name="com.google.android.maps");
• tried to include permission tag uses-permission (...permission.MAPS_RECEIVE);
• tried to inform services version (android:name="com.google.android.gms.version");
• tried to generate keys for a own certificate and android.keystore under .android folder;

• file:

  <manifest package="com.myapp"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:anrdroid="http://schemas.android.com/apk/res-auto">
      <uses-permission android:name="android.permission.INTERNET"/>
      <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
      <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
      <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
      <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
      <application
              android:allowBackup="true"
              android:icon="@drawable/logo"
              android:label="@string/name"
              android:supportsRtl="true"
              android:name="android.support.multidex.MultiDexApplication"
      android:theme="@style/Default">
          <meta-data
                  android:name="com.google.android.geo.API_KEY"
                  android:value="@string/google_maps_key"/>
              <activity
                  android:name=".view.MainActivity"
                  android:icon="@drawable/logo"
                  android:label="@string/name">
                  <intent-filter>
                      <action android:name="android.intent.action.MAIN"/>
                      <category android:name="android.intent.category.LAUNCHER"/>
                  </intent-filter>
              </activity>
              <activity
                  android:name=".view.ActivityMap"
                  android:icon="@drawable/logo_row"
                  android:label="@string/name">
              </activity>
              ...
          </application>
          </manifest>
  

build.gradle

• tried different compile and build configurations (23, 22, 19 etc);
• tried different library versions (8.4.0, 7.80 etc);
• tried different library versions for appcompat library (23.2.1, 22.2.1 etc);
• used selective compile only for maps and dependencies or Google Services complete;
• tried to sign debug and release with same and different keys;

• file:

  apply plugin: 'com.android.application'
  
  android {
      compileSdkVersion 23
      buildToolsVersion '23.0.2'
      defaultConfig {

          targetSdkVersion 23

          versionName "0.0.1"
          multiDexEnabled true
      }
  
      signingConfigs {
          keystore {
              storeFile file("path_to_keystore")
              storePassword "my_password"

          }
      }
  
      packagingOptions {

          exclude 'META-INF/NOTICE'
          exclude 'META-INF/io.netty.versions.properties'
          exclude 'META-INF/INDEX.LIST'
      }
  
      dexOptions {
          javaMaxHeapSize "2g"
      }
  }
  
  dependencies {
      compile fileTree(dir: 'libs', include: ['*.jar'])

      compile 'com.fasterxml.jackson.core:jackson-core:2.5.4'
      compile 'com.fasterxml.jackson.core:jackson-databind:2.5.4'
  }
  

Code

• tried to extends AppCompat, FragmentActivity;
• tried to request permission in api 6 using ActivityCompat.requestPermissions();
• tried call MapsInitializer.initialize() and check return;
• tried to use only fragment into layout file, informing context etc;
• tried to use fragment inside FragmentLayout;

• files:

  public class ActivityMap extends FragmentActivity implements OnMapReadyCallback
  {
      private GoogleMap map;
  
      @Override
      protected void onCreate(Bundle savedInstanceState)
      {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_map);
          SupportMapFragment fragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.activityMapID);
          fragment.getMapAsync(this);
      }
  
  
      @Override
      public void onMapReady(GoogleMap googleMap)
      {
          map = googleMap;
          map.addMarker(new MarkerOptions().position(new LatLng(-34, 151)).title("Marker in Sydney"));
      }
  }
  

activity_map.xml:

    <fragment android:id="@+id/activityMapID"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        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:layout_width="match_parent"
        android:layout_height="match_parent"/>

Others

• checked my network connections and firewalls;
• checked if the keys were available and working in Google Console;
• tried to clean, rebuild project and invalidate caches for Android Studio many times;
• tried to wipe data, restart and clean device (and tested in more than one device);
• removed the app through adb using "adb shell pm clear ...";
• no nullpointers, onMapReady returns a valid map and debugging code, everything works fine;
• if I create a new map app using Android Studio, everything works fine;

In first call, I have this log:

    03-21 09:34:28.478 25570-26174/com.myapp I/LoadedApk: connected(), package name=com.google.android.gms ,class name=com.google.android.gms.maps.auth.ApiTokenService

Then after second call, I have the message that my key is invalid:

    03-21 09:35:22.596 25570-25633/com.myapp I/LoadedApk: connected(), package name=com.google.android.gms ,class name=com.google.android.gms.clearcut.service.ClearcutLoggerService

    03-21 09:35:37.973 25570-28472/com.myapp E/Google Maps Android API: Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).
    03-21 09:35:38.363 25570-25582/com.myapp I/LoadedApk: connected(), package name=com.google.android.gms ,class name=com.google.android.location.internal.GoogleLocationManagerService

I really don't know what to do anymore. Does someone have any idea what could be happening?

Thanks in advance.

Answer 1

Finally I found the problem.

In another part of my code, I was calling

    HttpsURLConnection.setDefaultSSLSocketFactory(sslContext.getSocketFactory());

To simplify all the calls I do for HTTPS. The issue was when Google Maps tried to call its server: it was using the same SSL Context I've set before so it couldn't connect on Map servers.

I've just commented that line and changed my code to:

    URLConnection urlConn = new URL(myAddress).openConnection();
    HttpsURLConnection https = (HttpsURLConnection) urlConn;
    https.setSSLSocketFactory(sslContext.getSocketFactory());

and everything worked like magic!

Thanks everyone!

Answer 2

Try to add this line at the end of the build.radle

apply plugin: 'com.google.gms.google-services'

Add it in inside of manifest tag :

<uses-feature
        android:glEsVersion="0x00020000"
        android:required="true" >
    </uses-feature>
