Android :: Camera API Sample Code
I tried google's camera API sample code. I found there are 2 problems: 1> It only can take picture in Landscape orientation 2> After click the space "key", the application crashes.

Android :: How To Compile Sample Code
I'm breaking into GUI programming with android, trying to compile and analyze Lunar Lander sample program. The instructions for using Eclipse say to select "Create project from existing source" but that option doesn't exist. If I select File->New->Project I can select "Java project from Existing Ant Buildfile". Using that I've tried selecting various xml files as "Ant Buildfile" but all give me the "The file selected is not a valid Ant buildfile" error.I just want to run GUI sample projects, preferably with Eclipse. Any useful tips will be appreciated.

Android :: Sample Code In GPL3 Release
I used some of the code from the Android sdk examples.Legally I know apache is compatible with GPL3 (license for my code), but what do I do about the copyright notice in the code?Do I keep the "Copyright (C) 2009 The Android Open Source Project" and apache license and just indicate the content was changed.Has anyone dealt with this? The Legal dept has no clue.

Android :: Sample Code / Application Stopped Unexpectedly
The code seems no problem when I run it, but it stop unexpectedly in the emulator. I read some answer in the forum, It has to look at the logcat to see about the exception handler.

Android :: Use AIDL Tool From Command Line Using SDK Sample Code?
My question concerns using aidl.exe (on a Windows system) from the command line. This question has nothing to do with Eclipse, Netbeans, etc. Included with the Android SDK are the following three AIDL definition files: IRemoteService.aidl IRemoteServiceCallback.aidl ISecondary.aidl. Located in the following directory: C:android-sdk-windowsplatformsandroid 2.1samplesApiDemossrccomexampleandroidapisapp. For the sake of simplicity, I copied aidl.exe into the above directory. Then, from a console Window, I successfully used the following two commands to generate .java files: C:Android-projectApiDemossrccomexampleandroidapisapp>aidl IRemoteServiceCallback.aidl C:Android-projectApiDemossrccomexampleandroidapisapp>aidl ISecondary.aidl. Invoking these commands produced the files: IRemoteServiceCallback.java and ISecondary.java, respectively. So far so good. I note that both .aidl files are simple; they include no 'import' statements..............................

Android :: Uploading An Image In A Multipart Message - Sample Code
In response to a request over here: http://bit.ly/E1Qqm This is some sample code for uploading an image to the web, as part of a multipart message. It assumes that the photo is stored on the SD card as "photo.jpg". You'll need to download and add a couple of jar files to the project's built path - commons-httpclient.jar and httpcomponents-client-4.0-alpha4. It is working on my device. However (big caveats here) - it's much slower than I would like, and much slower than other applications I've installed that upload photos. It also feels hacky - e.g. the way the background thread communicates problems with the upload to the main thread using variables. I'm sure there must be a neater way to do it. If you figure out a way to improve the code, code:............

Android :: Force Admob To Refresh On Droid / Sample Code For It?
I have an app with Admob ads on it but I find that when I use it the ad almost never refreshes because I don't change activities, instead I just update a text view when buttons are pressed. I have tried searching this on Google but keep comming up short. I would like to tell the app to refresh the add occasionally, such as after two button clicks or something like that. Does anyone know how to do this and potentially have some sample code for it?

Android :: Point Of Synchronization - Bluetooth Chat Sample?
What is the point of the synchronization here? Why not just use: mConnectedThread.write(out); ? The code snippet is from the BluetoothChat sample for Android (found here) http://developer.android.com/resources/samples/BluetoothChat/index.html /** * Write to the ConnectedThread in an unsynchronized manner * @param out The bytes to write * @see ConnectedThread#write(byte[]) */ public void write(byte[] out) { // Create temporary object ConnectedThread r; // Synchronize a copy of the ConnectedThread synchronized (this) { if (mState != STATE_CONNECTED) return; r = mConnectedThread; } // Perform the write unsynchronized r.write(out); }

Android :: Sample Sync Adapter Demo Code - Intervals For Instructions
I've read through the SampleSyncAdapter project (http:// developer.android.com/resources/samples/SampleSyncAdapter/index.html). The main entry point for the SampleSyncAdapter appears to be the onPerformSync(...) method. In the documentation page for the sample, it mentions that "[onPerformSync]...gets called whenever the sync manager issues a sync operation for that sync adapter." Who is this 'sync manager', and at what intervals will it instruct the sync adapter to onPerformSync()?

Android :: Looking For Few Co Developers
I am looking for some fellow developers to build a few applications that work together to allow the android phone to take advantage of cheap telephony services provided over the internet. These are sms, voip, calling cards and similar such services.I have been investigating this quite a bit and developing an app to work with PennyTel but i have discovered an issue with the Android OS. Android is not designed to let you replace low level systems in your app and there for there is no way to capture out going sms etc. This means that to write an app that sends all out going sms via pennytel is impossible and that the only way around this is to write your own sms client like ChompSMS and i am sure this will apply to other parts of the phone as well.What i am looking to do is make a reusable system that uses intents to do things. A complete sms application that uses an intent to send the sms so that more sms providers can be added later, a dialer and outgoing call system that will fire an event for another app to make the call etc.What I want is sever apps that use intents not just to open their app but also to choose the outgoing their service uses. personally i want to write one of the outgoing paths and i am looking for some developers who would be interested in writing the more front end apps like the dialer and sms applications.If anyone is interested let me know as it is just too much work for one person and i am sure your apps will be used by many people as more and more people could right services they could be hooked into.

Android :: Hiding App Developers
Is there any way of hiding specific app developers that you don't link on the market? E.g. if one developer has made thousands of sound board apps or themes for an app that I won't be using - I could hide that developer and wouldn't see his/her apps on the market? If this is possible, I think it would make the market much less annoying when you have to scroll through hundreds of sound boards and app themes.

Android :: Catch 22 For Developers?
This would be some excellent support for the faithful Android developers. I have eight apps but live in Canada so I haven't been permitted to post them on the Market yet. Still I'm hoping Google might take this into account for Canadian developers who can't yet meet the sales criteria. I applied anyway and hope Google will respond so I can begin mobile testing.
