Android Maps v2 Couldn't get connection factory client

问题

I have a problem. I am getting a blank google map. I tried everything around the net. But nothing seems to solve this issue. I have pasted the logcat below. I have tried both debug key and release key. But both are not working. The map is not working. I just get a grey background with Google written below :( Please help

    </application>

</manifest>

[UPDATE]: I tried generating the sha1fingerprint again. I observed that the signature algorithm used is SHA256withRSA where as the example in the google dev site show SHA1withRSA could this be causing any problem?

回答1:

In your XML file you are using pld Google Map API v1.. And in your Manifest file you have wrote code for Google Map V2.. SO just add this in xml replace with old.

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment"/>

and yes also remove

<uses-library android:name="com.google.android.maps" />

from manifest file....

回答2:

Google map v1 is deprecated check this for Google map v2. Good tutorial

try using SupportMapFragmentin your XML

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    class="com.google.android.gms.maps.SupportMapFragment"/>

回答3:

Add this permission in your manifest

<permission
android:name="your.application.package.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />

remove this one

 <uses-library android:name="com.google.android.maps" />

and check whether you have google play services or not.
