Google Maps API and Facebook SDK for Android don't work anymore, probably because of the debug key

Question

My Android application makes use of two APIs: Google Maps API v2 (identified by the package com.google.android.gms.maps) and Facebook API (com.facebook) (this last one has been solved thanks to @RINK)

Both the services were installed in my project by following their official tutorials and they worked fine until yesterday, where something in my code changed and I obviously can't figure out what. I'm pretty sure that the cause is related to the debug/release key that signs my application before being installed on my testing phone.

In particular, I'm working with the debug key that it's stored in my personal folder (I'm on Windows + Netbeans) by default and it's regenerated every time I delete it: C:\Users\Alessandro\.android\debug.keystore.

Both Maps and Facebook need to know the SHA-1 fingerprint of such key, I've retrived it using keytool. Having it, I put it on the dedicated API service pages:

• Google's Console API in the form BB:0D:AC:74:D3:21:E1:43:67:71:9B:62:91:AF:A1:66:6E:44:5D:75;com.UpMap
• and Facebook's App Dev page, Key Hashes field.

As I said, everything worked fine but suddenly the Maps in my application became blank and Facebook Login raises an error:

I readed the question Android Facebook SDK 3.0 gives "remote_app_id does not match stored id" while logging in and I should be in the same problem, but the fact is that the "Key Hash" which I generated using keytool is good.

I've tried to:

• delete the stored debug key and regenerate it, updating it's SHA and saving it on Google and Facebook
• check if the API Keys provided by Google and Facebook and written in my AndroidManifest.xml are correct
• check if the package name of my app is correct
• clean and rebuild the entire project, including Google and Facebook source libraries

This is my manifest:

This is the code of the Activity that shows the Google Map:

        />

        <LinearLayout
            android:id="@+id/MapOverlay"
            android:clickable = "true"
            android:onClick="mapOverlayClick"

        >

                android:visibility="invisible"
            />
        </LinearLayout>

    </FrameLayout>

</LinearLayout>

And I use this line to retrieve the GoogleMap object in the code:

GoogleMap theMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.TheMap)).getMap();

I can't figure out what the problem is, maybe I think I'm signing the application with the debug key specified above... but actually the real used key is in another path?

Answer 1

I have facing same issue like this ,My problem is solved by print out the key hash sent to Facebook. put this code for getting the keyhash

try {
    PackageInfo info = getPackageManager().getPackageInfo(
          "com.facebook.login", PackageManager.GET_SIGNATURES);
    for (Signature signature : info.signatures) 
        {
           MessageDigest md = MessageDigest.getInstance("SHA");
           md.update(signature.toByteArray());
           Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
        }
    }
} catch (NameNotFoundException e) {
} catch (NoSuchAlgorithmException e) {
}

Answer 2

I have also faced the same problem while implementing the Google Map. Please be notices that the key you have generated from keytool should not be the debug key. It should be the that you fetch from the keystore file generated while exporting the signed application package.

If you want to run the .apk over the client side, you need to follow the above mechanism else for debugging at your own end. please validate whether the API key you have provided must not be expired.

Check your manifest for correct entries.

  <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="AIzaSyA9oeVdgN9F-8VOAXmCj1-WlAEk" />
