I have spent over 2 days reading over the documentation over at Google Cloud Platform to find out how to hook up my Android app to my Google Cloud Storage.
I don't know if it's just the documentation that's just bad or my lack of understanding but I have really not gotten any closer in implementing this. By contrast I remember it took me a couple of hours implementing Amazon S3 support in an earlier Android project so I'm not a complete idiot.
My requirement:
Upload images to my GCS account
Questions:
Is there a simple "Hello World" type of example for hooking up an Android app to GCS?
I don't need access to users data so does that mean that I don't need OAuth 2.0?
Thanks
You need to use app engine and can use cloud end points to build your application. Detail procedure for creating android app and using app engine as back-end are described here and here

I have been trying to learn how to create an app that allows people to upload images via the web or android.
I know that Android uses content providers to implement a mechanism for the sharing of data between applications. More specifically, Android uses the MediaStore API to make use of this functionality. However, that is limited to other Android devices.
I was wondering how I would go about connecting a web app made using reactjs to an Android app preferably using firebase. However, if it isn't possible in firebase that would be okay too,
I am a beginner in web app development, so I am not particularly sure about how the software's architecture will look like.
I have been struggling to find an updated concise solution online. Can anyone point me in the right direction and if not point me to some resources that will guide me in the right direction.
Thank you!
Attach/configure both of your application to use same database and storage bucket in firebase
As you can see I connected my android application as well as web administration application to same firebase project.
As you can see there is an add app option in firebase console where you can select platform. Register both of your application on same project and thats it.
I want to develop android application like Photofeed application as mentioned on Google cloud sample link or like Instagram. For that I need App Engine SDK but i am not getting how i will achieve this functionality. In my app, i want exact functionalities (uploading image, like and comment on that photo) like Photofeed app shown on that link. For that I'll have to use Google Cloud Storage but Photofeed is for Webapp and i want to develop Mobile app. For that i also referred Mobile back-end starter but not getting much idea. Its quite confusing. Please guide me to develop this application. Is it possible to use Photofeed sample java classes in my android application?
Thank you.
You will need to install Google Plugin for Eclipse and make Android Connected App Engine Application. This is a good starting point.
You can make similar app or any app that connects to GAE as backend in 4 steps as follows:
Make your entity classes: You can use JPA, JDO or Objectify to access the Data Store or use its API directly as done in the sample NoSQL classes (The easiest way is Objectify IMO). Or you can use Google Cloud SQL as done in the SQL classes of the sample ( I never used that in a project so I do not know if there is another way beside the API).
Make REST Endpoints: You can use Google Cloud Endpoints to make REST API for your own app. This will allow you to develop Android, iOS and JavaScript clients in unified way. If needed you can secure it using OAuth too.
Generate Client Libraries: If you are using Eclipse, Google Plugin will provide that in the context menu of the App Engine project so you simply right click and click Generate Client Libraries. It can be done using command line too.
Consume the endpoints in the Android app: This is done really simple as explained here.
Note : You will need a Servlet to upload photos to Google Cloud Storage. You can make use of the one in the sample.
I am a beginner in Android app making. I want to build a basic Cloud app which can take back up of the user's data and can store it on remote server. I know there are millions of such app, but would like to know some link that I can refer to begin my App building.
I hope I am clear with my question.
I recommend using Google App Engine. You can do all of the coding in eclipse, and once you have it set up properly it's fairly painless to deploy your webapp to the server and start testing your android app.
If you require a true relational database, google app engine makes you pay extra. If you don't however, there is no charge for the standard datastore. Also, app engine is free until you have lots of traffic to/from the server.
You can develop in Java or python. Here is the setup guide for eclipse (Java).
I am looking into building an android app, which holds some simple data (probably stored in sqlite). I also have a app engine app which I intend to be an online data store for the information (the app engine app is wrote in python).
The question here is, what is the best way to authenticate a user with the app and how to get the data from the android app to the Google data store?
Thanks
Mike
You could use Google Account authentication and follow this useful post about Authenticating against App Engine from an Android app
You can also give a look at the SampleSyncAdapter sample from the SDK
If you want to authenticate using OAuth, you can do that. The only trick is that you need to launch the flow in an internal WebView, because App Engine's OAuth implementation doesn't allow custom protocols in the redirect. I recommend the Signpost library. If you'd like an example, the 2cloud Android client is licensed under the MIT license (full disclosure, I'm the lead dev for 2cloud). The benefit of this is it allows you to support Android 1.5 and higher. The Accounts API is only supported starting in 2.1.
Another option is the Accounts API. #systempuntoout has good links for that, so I won't reinvent the wheel here.
Finally, it might be worth taking a look at the App Engine-powered Android Eclipse project that was demo'd at I/O this year. It makes keeping code in sync and shared between the two simple. Only downsides are it requires Android 2.2 or higher, and it requires you to write in Java on the App Engine side and GWT for the client side.
It has been a couple of weeks and I am having so much trouble making C2DM work. I've read a million guides and watched video tutorials but have had no luck. I just need a way to communicate with my server and my phone in the simplest way. Any help?
If you're still interested in trying C2DM, try installing the Google Plugin for Eclipse and use it to generate the Android / App Engine sample project. It should be able to generate a skeleton project that is able to communicate between AppEngine and a basic Android application. You could verify that the sample works and use it as a basis to debug your custom application.
There was also a related AppEngine + Android session at Google I/O this year.
The easiest way to get push into your app is to use a third party push provider like Urban Airship or Xtify. Instead of writing the code to interface with google directly you integrate the third party SDK into your app and they handle the messy stuff.
Additionally, you don't have to worry about scaling if your app gets (or already is) big. And going cross-platform (iOS, Blackberry) is that much easier.
