Google maps on Android not working on app but demo is fine

Question

I cannot get Google Maps to work on my app.

I see a blank screen; no grids show, only the google logo and the +/- zoom buttons.

What I have done:

• I have the "Google Maps Android API v2" API enabled
• I have added my project along with the demo project to the API credential list on Google console
• I've also added the required permissions for Internet, location, com.google.android.providers.gsf.permission.READ_GSERVICES.
• Even added the "MAPS_RECEIVE" permission as some posts suggested
• Also added the 'meta-data' google_play_services_version

Since the demos are working, I literally copied MultiMapDemoActivity and its files into my project and tried opening map, to no avail.

The problem may be linked to this issue. However, it seems like they can't get map to work at all.

Here is the interesting bit that I noticed, I usually get this:

10-02 12:29:20.376: D/REQUEST(5826): Connection opened to:https://clients4.google.com/glm/mmap/api
10-02 12:29:20.376: D/REQUEST(5826): Open Connection

Followed by this:

10-02 12:21:45.361: D/REQUEST(5826): DRD(80): 62|132
10-02 12:21:45.361: D/REQUEST(5826): Close
10-02 12:21:45.361: D/REQUEST(5826): Error processing: com.google.maps.api.android.lib6.b.d@42caa7b8 not retrying
10-02 12:21:45.361: D/REQUEST(5826): Retrying: com.google.maps.api.android.lib6.gmm6.c.a@4296a530

• Also, not sure if this is relevant, but as soon as I click to open the map, or click on the map after it has opened and is showing a blank view, I see this:

    10-02 13:03:32.978: E/DatabaseUtils(15468): Writing exception to parcel
    10-02 13:03:32.978:/DatabaseUtils(15468): java.lang.SecurityException: Permission Denial: get/set setting for user asks to run as user -2 but is calling from user 0; this   
    requires android.permission.INTERACT_ACROSS_USERS_FULL

EDIT #1

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

EDIT #2 Also, the declared package name was com.A.B.C (the manifest); whereas the activities of my project had the structure of com.A.B..

I have since updated my project structure to match that of the manifest, but I still see the same errors as before, nothing changes. I'm really at sea here, since I cannot understand what could be going wrong here.

Some help to resolve this will be appreciated, thanks!

Answer 1

It turns out that I had read n-1 questions regarding this issue here. Finally, after continuous searching everywhere, I stumbled upon the answer here by @Jack.

Basically the line:"HttpsURLConnection.setDefaultSSLSocketFactory(...)" was the culprit in my code. I commented it out and everything worked fine.

NOTE: I have not tried to keep the line of code and modify it to make maps work yet. If I need/do it, I'll post a comment.

You need to add your SHA1 fingerprint to the public API access. Go to eclipse > preferences. Android > build and copy your default eclipse SHA1 fingerprint.

Now go to https://console.developers.google.com select your app, 'APIs and auth' > 'credentials' > and click on 'Edit allowed android applications' put your SHA1 figerfirnt like that:

XX:XX:XX:XX:XX...XX;com.your.pakage.app
