I had the same problem. I solved in google api console >> consent screen, and adding a Product Name.
I try this tutorial: http://www.androidhive.info/2014/02/android-login-with-google-plus-account-1/
In the main activity you need change .addApi(Plus.API, null) by .addApi(Plus.API, Plus.PlusOptions.builder().build())
For me the problem was that I had not created the credentials for the app.
Went to Google Developers Console > Credentials > Create New Client ID
filled the corresponding package name and SHA1 for my app, reran the app and then it worked!
In case you are using MapView, make sure you are following the guidelines
i.e.
"When using the API in fully interactive mode, users of this class must forward all the activity life cycle methods to the corresponding methods in the MapView class. Examples of the life cycle methods include onCreate(), onDestroy(), onResume(), and onPause(). When using the API in lite mode, forwarding lifecycle events is optional. For details, see the lite mode documentation."
#Override
public void onResume() {
mapView.onResume();
super.onResume();
}
#Override
public void onDestroy() {
super.onDestroy();
mapView.onDestroy();
}
#Override
public void onLowMemory() {
super.onLowMemory();
mapView.onLowMemory();
}

I am struggling with a problem to display my reverse geocoding results automatically. It works fine when I click button to get location, but I want it to simply display the location automatically when the app is loaded.
My code is in a Java class called geocoding, eventually i want to display this code on a marker on my map, which i have already created.
but this thread is to eliminate the button and display location as son as map loads.

I am following this tutorial https://developers.google.com/+/mobile/android/recommend to integrate +1 button in my app.
As soon as I put this code in xml I get errors in GraphicalLayout

Help !!
Android Studio solution:
I just got a simple example working by starting with the code from the gplus-quickstart, and then adding a +1 button using the guide linked in the question.
build.gradle dependencies:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.1.1'
compile 'com.google.android.gms:play-services:7.0.0'
}
AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.plustest.daniel.googleplusone" >
<application
android:allowBackup="true"

</intent-filter>
</activity>
</application>
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
</manifest>
I added com.google.android.gms.plus.PlusOneButton to the bottom of activity_main.xml, which is based on main_activity.xml from the quick start code:
xmlns:plus="http://schemas.android.com/apk/lib/com.google.android.gms.plus"
android:id="#+id/plus_one_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
plus:size="standard"
plus:annotation="inline" />
MainActivity.java, with the added +1 button.

EDIT:
I've discovered that in the onConncectionFailed() method, if I remove the first "if()" that checks if the processDialog is showing, when the application starts, without clicking anything, a dialog of google+ appears asking me to login. this is strange
EDIT:
I resolved my problem using a normal Button and implementing onClick on it, following the tutorial of Google Dev
Have you registered your application on the Google developers console? You need to make sure your Android application has an associated client ID with the Google+ API enabled.
https://developers.google.com/+/mobile/android/getting-started#step_1_enable_the_google_api
After doing some digging I realised that providing the release SHA-1 to the console only gave me the ability to run my project with a working sign-in button if and only I generated a signed APK and installed the APK manually and not through Android Studio.
I figured changing the SHA-1 to debug was the solution but I wasn't able to change it until now.
To change your SHA-1 from the release version to the debug version so you can install a working/testable apk through Android Studio:
Open Google Cloud Console > Open API Manager > Click on Credentials.
Under OAuth2.0 Client IDs > click Android Client for your app and change the SHA-1 to your debug version (following these instructions should help you to retrieve your debug SHA-1: https://developer.android.com/studio/publish/app-signing.html)
After doing so, save your new credentials in the Cloud Console and return to the screen to generate your configuration file. You should notice your changed SHA-1. Now generate the config file and paste it into app/.. project directory. Clean, rebuild, and run your project and your signin button should now work as expected.
I am having problem while implementing Google +1 button in my android application.
I followed instruction on this link and my activity is showing g+ button successfully but after clicking on button, it is showing a progress bar on the button only, please tell me how +1 button works in android it should open a login internet or what?
I am not implementing signin with google just +1 button in my app. Hhere is my code, this is part of my code so it is not that proper.

You need to be signed in for this to work, but you do not have to have a sign in button on your app.
If it is enabled (you can click on it) then you are already signed in and I suggest you check that you have specified a valid url.
Your code looks different to mine (I use a GameHelperListener) but as long as you have followed the documentation accurately it should be fine.
If you want to see it work, just download an app that has a +1 button on it, and try it.
Change url like
url="https://market.android.com/details?id=xxx.xxx.xxx";
Also implement methods
ConnectionCallbacks, OnConnectionFailedListener and extends activity
I've been trying to implement v2 of android's MapView. I got it working just fine with the exception to this bug.
This is what it looks like when I load the app from scratch...
As you can see, no problems there.
Now, when I press the "Home" button and try to access the app from the "recent apps" window i get this:
and it stays that way until i dismiss the app and re-load it from scratch.
Here is some of my code.

I Disable hardware acceleration at file manifest.xml, and my application doesnt show black map again in second load. i try it in emulator.
<application android:hardwareAccelerated="false">
...
</application
from this article: http://developer.android.com/guide/topics/graphics/hardware-accel.html
A bit late but,I found out that WebViews (even on other fragments) sometime "crash" the GL engine or something which results in black screens in the MapView. I found in LogCat this:
09-30 10:58:17.765: E/libEGL(29805): call to OpenGL ES API with no current context (logged once per thread)
09-30 10:58:17.765: W/Adreno200-EGL(29805): <qeglDrvAPI_eglSwapBuffers:3421>: EGL_BAD_CONTEXT
09-30 10:58:17.765: W/HardwareRenderer(29805): EGL error: EGL_BAD_CONTEXT
09-30 10:58:17.775: W/HardwareRenderer(29805): Mountain View, we've had a problem here.
Switching back to software rendering.
To fix this when the WebView is detached I call the destroy function, in a Fragment so:
#Override
public void onDestroyView() {
if (webView != null) {
webView.destroy();
webView = null;
}
super.onDestroyView();
}
Maybe it'll give you a direction on solving this issue as well.
