I have created an Android Map API key for V2, can't display a map

Question

I have created a Google API key for version two and used that in the manifest, but I'm unable to display map on the device.

I have followed everything provided in google map documentation. also I used this link.

MainActivity.java.

package com.example.googlenewmap;

    import android.os.Bundle;
    import android.support.v4.app.FragmentActivity;

    import com.google.android.gms.maps.GoogleMap;
    import com.google.android.gms.maps.SupportMapFragment;
    import com.google.android.gms.maps.model.BitmapDescriptorFactory;
    import com.google.android.gms.maps.model.LatLng;
    import com.google.android.gms.maps.model.MarkerOptions;

    public class MainActivity extends FragmentActivity {
        static final LatLng HAMBURG = new LatLng(53.558, 9.927);
        static final LatLng KIEL = new LatLng(53.551, 9.993);
        private GoogleMap map;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            map = ((SupportMapFragment) getSupportFragmentManager()
                    .findFragmentById(R.id.map)).getMap();

            if (map != null) {
                map.addMarker(new MarkerOptions().position(HAMBURG)
                        .title("Hamburg"));
                map.addMarker(new MarkerOptions()
                        .position(KIEL)
                        .title("Kiel")
                        .snippet("Kiel")
                        .icon(BitmapDescriptorFactory
                                .fromResource(R.drawable.ic_launcher)));
            }

        }

    }

                </intent-filter>

        </application>

    </manifest>

How can I fix this problem?

Answer 1

What key you are using?

There are two types of keys debug key and release key. While signing apk, you want to use release key. For that you want to compare that with signed apk

Step 1:

Say for example your apk name is A and you are signing and creating a keystore for A.apk ie A.keystore will be created in some drive location.Let's consider it in E drive.

step 2:

Now locate to jdk in C drive(Considering for windows and assigning C drive)

C:\Program Files\Java\jdk1.7.0\bin>keytool -list -v -keystore E:\A.keystore -alias A

So it will create SHA-1 finger print

Debug key is normal which you extract as usual.
