Android :: Initialize Sender ID For C2DM Without Using A Hard-coded Value?

Oct 18, 2010

I'm adding Android C2DM to a Android library project. I started with the com.google.android.c2dm package that is included with JumpNote and Chrome To Phone. In order to use this package, you have to subclass the C2DMBaseReceiver service which takes the Sender Id as an argument to it's constructor. In JumpNote, this argument is initialized using a hard-coded static variable in a config class. However, in an Android library project, which may be used by multiple concurrently running apps I don't think I can use a hard-coded static variable (that is, I believe it could lead to problems when/if multiple apps are trying to access/modify the static variable). I tried to think of a way to initialize the Sender Id without using a static variable and am stumped so far.The obvious solution would be to use the Manifest or a Resource string or a combination of the 2. For example, in strings.xml I might have a "ac2dmSender" string, which is accessed in a meta-data child of the C2DMReceiver service declaration in the manifest. However, it seems that you cannot get a reference to the PackageManager or ResourceManager from a static context, so there is no way for me to then retrieve the meta data in such a way as to pass it in to the constructor of C2DMBaseReceiver.

Android :: Strings Generated By Substring Not Treated As Hard Coded Strings

Nov 21, 2010

Dear all, I'm making a simple file decoder for Android 2.2 that needs to find the filename of the encoded file from a header. This filename should then be used as the filename for the decoded file (as you would expect).The filename is identified by the substring name=, so the actual name starts 5 places after that. The line is read by a BufferedReader and temporarily stored in currLine.For some reason I can't understand nor find on the web, Strings do not always seem to be Strings.Gives no output file, nor an IO exception. The string is parsed properly though: from the System.out debugging lines.

Android :: Treo 755p - Color Coded Calendar

Jul 18, 2010

Had a Treo 755p & LOVED my calendar! Just got a Droid and I HATE Google Calendar. I can't believe such great company hasn't listened to the users (look at all the posted all over the web!) and altered it to have color coded categories in ONE calendar. I'm really torn about the fun apps vs. the calendar I LOVED (tasks and notes were better too). I'm still within my 30 days, so unless I can find a 30-day color coded calendar view, I may just take it back. Has anyone found an app that works like the Palm calendar?

Android :: Registering For C2DM Framework

Sep 5, 2010

I'm trying to test the C2DM framework. I got the confirmation email a couple of days ago and then tryied to create a client that could register. For that purpose, I created a simple client following the steps described in this tutorial:
http://code.google.com/intl/es-419/android/c2dm/index.html.

The Android manifest file contains among other things this code:
<permission android:name="com.bilthon.ufrj.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
<uses-permission android:name="com.bilthon.ufrj.permission.C2D_MESSAGE" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<uses-permission android:name="android.permission.INTERNET"/>
<receiver android:name=".C2DMReceiver"
android:permission="com.google.android.c2dm.permission.SEND">
<intent-filter> <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<category android:name="com.bilthon.ufrj" /> </intent-filter>
<intent-filter> <action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="com.bilthon.ufrj" /> </intent-filter> </receiver>

And then, the main activity launched when the program starts has the following code:
Intent registrationIntent = new Intent("com.google.android.c2dm.intent.REGISTER");
registrationIntent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0));
// boilerplate registrationIntent.putExtra("sender","mytestemail@gmail.com");
Log.d("WelcomeScreen","mytestemail@gmail.com");
startService(registrationIntent);

I also registered a google account on the AVD running my client, as they said it was required. But the problem is that I cannot get the broadcast receiver to "wake up". I don't know what could be wrong. By analysing the logs, I can see that the registration intent is created and apparently used correctly, but the receiver code just never is executed, what could be wrong?

Android :: C2DM Properly Working On Emulator

Aug 20, 2010

I looked all over the web and in this group for a solution but I don't seem to have any luck. I'm probably not the only developer that needs to try C2DM on the emulator so a solution to this could be quite useful. First of all let me say that I'm running the latest Google APIs 8 rev 2 as AVD which should have all the necessary magic to allow me to run C2DM (it even has all the market components to run the LVL). I tried both Chrome to Phone and Jumpnote and it was impossible to make the C2DM service work. - Chrome to Phone fails when trying to connect from the Android app running on the emulator with a "Error: Unable to connect". On the Chrome to Phone site they recommend that Talk should be tried first and that the Market should be available (none of these come in the emulator image and I'm not sure if I should even try to install them on the emulator). - Jumpnote does not synchronize automatically and gives me an error: "Error calling remote note sync RPC" (when I do a manual sync I can see the docs being synchronized but looks like C2DM, which enables the auto sync, is broken). I also heard a comment that maybe port forwarding via adb could be necessary (but I'm really not sure this makes any sense).

Android :: Using C2DM To Receive Notification From Gmail Server

Aug 16, 2010

I'd like my Android app to receive notification when new messages arrive in my gmail account. I realize that the Android gmail client does not broadcast notification when it receives messages. Instead I want to utilize the gmail server's Cloud to Device Messaging capabilities to do this. I read the article at http://code.google.com/android/c2dm/ - the only "missing piece" for me is to understand how my app sends a
registration ID to the gmail server. Can someone please point me in the right direction?

Android :: How To Initialize Media Recorder In Background?

Aug 5, 2009

I am building a camera app, where photos and videos are continuously being captured and saved to the SD card. The videos are short (few minutes), and their length are preset with setMaxDuration(). When Media Recorder.MEDIA_RECORDER_INFO_MAX_DURATION_REACHED is reached, the video is saved, and a new sequence is initialized with something like: The whole process works fine, while the main activity is in the foreground. But, when I go to another activity (e.g. settings), the video recording works in the background only until max duration is reached. The file is saved, but a new sequence can not be started because prepare() fails. setPreviewDisplay() needs to be there, but it doesn't like not having a proper surface to attach to. I tried to use a dummy Surface, a dummy SurfaceHolder, or reuse the Camera with mMediaRecorder.set Camera(), but nothing works. Is there a way to initialize Media Recorder in the background?

Motorola :: Android AudioRecord Fails To Initialize

Nov 12, 2010

I've been having an issue with using AudioRecord for Android. I've read as much as I can find online about it, but I cannot seem to get a good initialization. I have tried the Android 2.2 emulator, 1.5 emulator and my phone, an HTC Incredible running Froyo. The emulators and my phone fail initialization. I've tried sampling rates of 8000, 11025, and 44100, formats of CHANNEL_IN_MONO/STEREO and CHANNEL_CONFIGURATION_MONO/STEREO, 8bit and 16bit encoding (8 bit makes the getMinBufferSize fail), and Audio Source of MIC and DEFAULT. All result in the variable test becoming 0 after running a get state(failed initialization). It seems from everything I've read that this should correctly initialize the object. I have played around with the multiplier on buflen, to have it range from 512 (the result of the function) to 102400 because I had heard that HTC devices require something above 8192. For testing my problem I made a new, small project that recreates my problem as simply as possible. I pull out the constants needed into local ints then run the constructor and access the getState method for checking if it worked. Code...

Android :: Get Name Of The Owner Of Phone - Email Sender

Jan 28, 2009

I want my application to send emails.

The user can pick arecipient from the contacts.

Then I generate the body text of the email and send it to the email app ( using something like http://androidguys.com/?p=3100#comment-5168).

The email body looks something like :

------------------------- Hi {recipientname}!

Please click the following link :

[url]

If you click that like, you will live forever.

{sendername} ---------------------------------

"{recipientname}" is replaced by the name of the recipient that I get from the Contacts via Contacts.People.

For convenience, I'd like to replace "{sendername}" with the name of the sender, that means the name of the owner of the phone. (As stored in the email app, under Account Settings -> General Settings -> Your name) So, obviously that name is stored somewhere, ...

My question:

Is there any way to access this name via a content provider ? Or is there any other way to get a string (e.g. "John Doe" ) with the name of the owner/user of the device ?
