its not that big deal but i found a Syntax error in the code for C2DM Registering from this site registrationIntent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0); where they missing the end ")" and here's my magical fix :) registrationIntent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0));

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?
I use this code for connection to my service, but when I put this line. this.bindService(service, conn, flags);
I receive error message: syntax error on token "}", { expected after this token ... (1)

I am developing android program under eplicse environment. I use svn to store all my files. But it seems that svn files cause some problem.
I got some errors like this:

It seems android system wallk all directories under src, and try to parse files under .svn folder. Is that bug?
I created a method and keep getting an error that I need to include a } at the end of my method. I put the } in and the error is still there! If I then delete that } the same error will pop up on a prior method; and that error wasn't there before. in other words, if i type the } on my most recent method then the error stays there and only there. if i delete it, it duplicates that error on my prior method.

I've run into the following issue:
Say I have an Animal class, which is parcelable, and I have a Dog class and a Cat class, which are subclasses of Animal and also implement Parcelable.
Say I have a service with the following AIDL interface:
sendAnimals(List<Animal> animals);
Now I'm calling this remote interface from some client application, passing it a List containing Cats and Dogs. What happens now is that android calls the Cat's and the Dog's writeToParcel() methods at the client side, but at the server side, the Animal's CREATOR is used, which calls Animal's readFromParcel() method. So the right data is sent from the client, but the wrong unmarshalling code is executed at the server.
I have tried to put this in the AIDL file:
sendAnimals(List<T extends Animal> animals);
This results in a syntax error from the aidl compiler though.
My current workaround is as follows: - In each specific Animal subtype's writeToParcel() method, I write the class name as a String into the Parcel as the first element. - In the Animal's CREATOR.createFromParcel() I read the first String out of the parcel, and based on that I create the appropriate type and call the appropriate readFromParcel() method.
I think this is kind of ugly though. I would expect the android framework to take care of this for me.
(My application is not actually dealing with animals, this is just to make it simpler to explain the issue)
Just getting started here. Working on an Android application, which needs to execute a google web search from within a ListView activity and display the results in that List View.
Such search would always be for the same "static" subject, such as "bowling alleys in Chicago...", so, the user will not be entering any search criteria. What is the proper way to accomplish this, please?
I am currently working on implementing C2DM stuff and have got this far.
1. Register the device and get back a device registration ID 2. The server gets a Client Authorization Token for "ac2dm" service 3. The server then sends a message to the device via C2DM using the registration id and the client authorization code and gets the following "NotRegistered" message back.
Meaning: NotRegistered — The registration_id is no longer valid, for example user has uninstalled the application or turned off notifications. Sender should stop sending messages to this device.
The thing is as soon as i get the registration id i am sending it to my server which is then sending a message via C2DM all within the space of 1 minute. so how can it not be valid?
I have registered for use the C2DM service and i would expect that if i was not registered with Google then i would not get a registration device id right? Although i don't remember getting an email from google saying i was registered apart from that when i registered to be white listed it did say something about being added to a list. Anyway your views and opinions are welcome.
I've posted a bigger chunk of the code below. You can see that initially QUOTE was procedural- coded in place. I'm trying to learn how to use declarative design so I want to do the same thing but by using resources. It seems like I need to access the string.xml thru the @R.id tag and identify QUOTE with that string value. But I don't know enough to negotiate this.

I am using the Emulator of version 8. and when i am trying to register the Android Application then it will gives the null registration ID. Please help me to resolve this issue. How can i register the Android Application with C2DM.My code is to register the App.
Intent registrationIntent = new Intent("com.google.android.c2dm.intent.REGISTER");
registrationIntent.putExtra("app", PendingIntent.getBroadcast(startCode.this, 0, new Intent(), 0)); // boilerplate
registrationIntent.putExtra("sender", "12786@gmail.com");
startService(registrationIntent);
handleRegistration(getApplicationContext(), registrationIntent);...............
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).

I am playing around with C2DM service. What I am concerned about is that I cannot test my device-side application from Android 2.2 emulator. The application was built more or less according to http://code.google.com/android/c2dm/index.html doc, but when register intent is sent from application, Logcat shows this: Unable to start service Intent { act=com.google.android.c2dm.intent.REGISTER (has extras) }: not found I also tried to run chrometophone and jumpnote applications and the result is the same when registring device. Any ideas? Is it possible to test C2DM service from Android emulator?
View 9 Replies View RelatedI'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.

However this page defines it as:

I thought I had a decent understanding of what was going on until I saw this second example. In the first case, you need the + character so that id 'label' is added to the R file, correct? In the second case, would the EditText's id not be added to the R file because it does not contain the + character?
Also, the second example does not include the android namespace on the id. Does having or not having the Android namespace affect whether that id will be added to the R file?

I try to tag the text with color but no color shows up and there are no errors.

I also try adding a new line - I've tried things like:
< LF> some text, space at beginning only for this post < /LF>
< CR> this didn't work either < /CR>
< p> some text, space at beginning only for this post < p>
But, no new paragraph / new line, carriage rtn happens.
Where is there information about the syntax of <shape> xml files. These can be used to define 2D graphics as I understand it. There are few spotty examples in the samples directory but that is all I have found.

I guess you could have one separate table for each type and the use something like FULL OUTER JOIN (simulated as sqlite doesn't support it) and sort on date. But this would be complicated because I still need to have unique IDs across all tables.
Maybe having a master list which has ID and date, and then JOIN in the types tables? But how bad is the performance of this using sqlite? I really like to avoid having a super table which contains columns all the combined types could ever need.
