Android :: Connect To Google App Engine

Aug 26, 2010

I have spent two days trying to decide on a way to upload and download data to the Google App Engine. Do I use REST or simple HTTP post/get? Do I use JSON or XML? Do I use java or Python. I am thinking probably use python and probably use REST. But which one out there? There are so many to choose from. None seem to work out-of-the-box, but need faffing around with bits of code from here and bits of code from there. And is not clear at the outset what am taking on or what the limitations are.

Android :: Easy Way To Authenticate POST Requests / From Google Android Client To Google App Engine?

Jul 9, 2009

I'd like to be able to send a POST request from an Android app to App Engine and have it linked to the user's Google account.I read that you need to obtain an authentication token and send it with the POST request. Does Android provide a way to request this token?And how would GAE process it?I feel like this should be easy and I'm missing something obvious.

Android :: AccountManager And Google App Engine

Nov 5, 2009

I'm currently working on a project that uses Google App Engine as a server. I see that prior to the Android 2.0 SDK there was no way to directly access a user's Google Account information for the purposes of authentication. Do the new Account Manager APIs now make it possible to automatically log a user into a GAE app? Is anyone else working on something like this? Are there any publicly available examples on how to accomplish this?

Android :: Syncadapter Using Google Account And App Engine

Oct 6, 2010

I am writing a syncadapter using google account and app engine. The account appears in account and sync, but when I try to select the account for syncing, I am getting a hard database error. I am trying to figure if this error is on mobile or the app engine. Further, what can be causing this error. Another error that I am getting is failed to find provider info.

Android :: Google App Engine - Supported XML Binding Tool Available?

Feb 14, 2010

A REST XML (not JSON!) Web Service should exchange XML Schema specified XML between a Google App Engine and an Android app. I wanted to use XStream for both, however, I could not get it to work for the Google App Engine, therefore to me Apache XMLBeans is the next best choice (JAXB does not work on both).

However, with Google App Engine there is no problem, but on Android, I get several severe exceptions (eg. due to the usage of the Stax API with its javax.xml.* packages). So, Is there any other XML-binding possibility to stream XML documents on GAE and Android? If not, is it possible to patch Apache XMLBeans to work with Android?

Android :: Send Data To Google Application Engine Datastore

Dec 31, 2009

I need to write an application that sends data to the Google App Engine from Android. The data that I would like to send can be described by a typical database record. Each record has some integers, strings, dates, etc. I would like to keep the connection details hidden/secured so that someone can't create false data in the datastore, if it it's not too involved. My question is: what is a good way to get this data from Android devices into the GAE datastore? If you could post a link to the appropriate Android libraries, or a link to how this has been done in the past, that would be really helpful.

Android :: Using HTTP Post On An Android Device To Put Data On Google App Engine Blob Store

Nov 14, 2010

I am trying to post data to the Blob Store on google's app engine, this code runs without throwing any exceptions, but on the blobstore end there is no log on the post request at all. The server side stuff works when i post using a form (albeit with mime data). I have allowed my android app to use internet. This is a stab in the dark but if any of you folks might have had an issue like this before perhaps the problem i am having might ring a bell

I have an Enco B046 car radio which incorporates Android 3.2.2

All was working fine last year and had installed all my apps etc but recently tried to connect to the Market/Play Store to install other apps and it hung for a while then gave me the error:

Android :: Google News / Weather Widget / Unable To Connect?

Jun 16, 2010

Was wondering if anyone has noticed a problem with the Google News & Weather widget today? I installed this on my EVO (Genie Widget.apk) because I love its simplicity and elegance, but today it's telling me "Sorry, unable to connect. Please try later" with a "Retry now" button. Just wanted to know if it's only my phone or everyone's? I tried rebooting, also tried stopping and uninstalling/reinstalling but to no avail. If it's happened to other people before and there's a trick to fixing it, that would be great to know too.

Android :: What Does 3D Engine Do?

Oct 18, 2010

I'm interested in developing an android application that will display a globe of some sort like Google Earth. I've never used opengl or have any experience with graphic programming so I'm here to learn some basics. Now, I know there are things like the Unity or Ogre that help facilitate graphics but what exactly do I gain from using these engines as opposed to just using opengl api to render graphics? Why do you use engines like Ogre as opposed to straight up opengl?

Android :: Authenticating To App Engine

Dec 26, 2009

I've been working for the past couple of days to allow users to login to an android app with their gmail account and pass the authentication token to my app hosted on app engine - so i can download xml from my web services hosted on app engine as if the user logged into the app directly. There is a lot of info on ways to get the google auth code and the auth cookie and then pass the cookie in the header of an http request - but no info out there on doing all of this from android and going as far as to add the cookie to the remaining http requests. So, now that's it's working, i thought i'd compile it all together and post the solution here in my blog - enjoy.

Android :: IntentNotFoundException For TextToSpeech.Engine

May 7, 2010

I am trying to implement text to speech by following this article on the Android Developers Blog. It suggests the following code for installing text to speech data if it is not supported.


This throws an Exception:

ActivityNotFoundException: No activity found to handle Intent

However, I am using the code here to determine the the intent is actually supported. Here is the list representation:

[ResolveInfo{43cc5280 com.svox.pico.DownloadVoiceData p=0 o=0 m=0x108000}]

Why doesn't this work?


I don't know why, but it seems to work now.

Android :: Best Practice For Specifying Pronunciation For TTS Engine?

Aug 16, 2010

In general, I'm very impressed with Android's default text to speech engine (i.e., com.svox.pico). As expected, it mispronounces some words (as do I) and it therefore occasionally needs some pronunciation guidance. So I'm wondering about best practices for phonetically spelling out those words that the pico TTS engine mispronounces. For example, the correct pronunciation of the bird Chachalaca is CHAH-chah-LAH-kah. Here is what the TTS engine produces: mTts.speak("Chachalaca", TextToSpeech.QUEUE_ADD, null); // output: chuh-KAL-uh-KUH mTts.speak("CHAH-chah-LAH-kah", TextToSpeech.QUEUE_ADD, null); // output: CHAH-chah-EL-AY-AYCH-dash-kuh mTts.speak("CHAHchahLAHkah", TextToSpeech.QUEUE_ADD, null); // output: CHA-chah-LAH-ka mTts.speak("CHAH chah LOCKah", TextToSpeech.QUEUE_ADD, null); // output: CHAH-chah-LAH-kah Here are my questions. Is there a standard phonetic spelling recognized by the Android TTS engine? If not, are there some general rules for making custom pronunciation spellings that will make the spellings more likely to be correct in future TTS engines/versions? It appears that the Android TTS engine ignores text case. What is the best way to specify emphasis?

Android :: Gamine Game Engine 0.2

Apr 29, 2010

I've just released version 0.2 of Gamine, an open source 3D game engine for Android devices: This release adds lots of major features, including particle effects, OBJ file import, picking, text rendering, transparent rendering, and more. Although it's still a very early version, I believe it is now complete enough to be used for real games. So give it a try, and I'd really appreciate any feedback about it.

Android :: Sound Engine Performance

Oct 5, 2009

I am working on an app that uses the SoundPool class to play sounds. Basically every n milliseconds I need to play up to 16 sounds and I need this to be as steady as possible. The best solution I found so far is to use a java.util.Timer and the scheduleAtFixedRate method (setting also a THREAD_PRIORITY_URGENT_AUDIO in the TimerTask run method), the result is pretty good but it is still not perfect and sometimes the executions get slightly delayed. Is there some other way I should try to play sounds _exactly_ every n milliseconds? Different threads, some kind of optimization, stuff like this?
