[android-beginners] Parcelable Class parameter input (1) unknown type
Hello,
I tried to create a simple custom object that I can use as a
Parcelable class for my bound service.
I did everything as described in the documentation. Maybe you can help
me solving this problem.
My code is constructed as follows:
src
--de.test.samples
--DialogActivty.java
--Person.java
--RemoteService.java
--IRemoteService.aidl
--Person.aidl
gen
--de.test.samples
--IRemoteService.java
--R.java
Person.java:
package de.test.samples;
import android.os.Parcel;
import android.os.Parcelable;
public class Person implements Parcelable {
private int mAge;
private String mSurName;
public static final Parcelable.Creator CREATOR = new
Parcelable.Creator() {
public Person createFromParcel(Parcel in) {
return new Person(in);
}
public Person[] newArray(int size) {
return new Person[size];
}
};
public Person() {
this.setMAge(0);
this.setMSurName("");
}
public Person(int age, String surname) {
this.setMAge(age);
this.setMSurName(surname);
}
private Person(Parcel in) {
setMAge(in.readInt());
setMSurName(in.readString());
}
@Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(getMAge());
dest.writeString(getMSurName());
}
// ...getter & setter...
}
Person.aidl
---
package de.test.samples;
parcelable Person;
RemoteService.java
--
package de.test.samples;
//imports
public class RemoteService extends Service {
Person p = new Person();
private final IRemoteService.Stub binder = new IRemoteService.Stub()
{
@Override
public int giveMeAnAge() throws RemoteException {
Random generator = new Random();
return generator.nextInt(100);
}
@Override
public String determineStatus(Person input) throws
RemoteException {
if(input.getMAge() > 50)
return "The person is old.";
else
return "The person is young.";
}
};
@Override
public IBinder onBind(Intent intent) {
return this.binder;
}
}
IRemoteService.aidl
---
package de.test.samples;
interface IRemoteService {
int giveMeAnAge();
String determineStatus(in Person input);
}
DialogActivity.java
---
package de.test.samples;
//imports
public class DialogActivity extends Activity {
private IRemoteService myServ;
//...
@Override
public void onCreate(Bundle savedInstanceState) {
//...
int tempAge = myServ.giveMeAnAge();
Person myPerson = new Person();
myPerson.setMAge(tempAge);
myPerson.setMSurName("Johnson");
mStatus.setText(myServ.determineStatus(myPerson));
//
}
//...
}
In IRemoteService.aidl
I can not define the method String determineStatus(in Person input);
because the type Person is unknown.
What did I wrong ?
Can please anyone help me ?

[android-beginners] Re: how to stop sound notification/let it only play once?
OK. And i have to ad, that hte virbation is only vibrating once,
because it isn't a notification.vibrate(), but a "private Vibrator
vibrator;"
As the Flag "FLAG_ONLY_ALERT_ONCE" seemed to be not working.
Is the Flag "FLAG_ONLY_ALERT_ONCE" not working?

[android-beginners] Persisting app data (not preferences)
Hi, How may I read and write some ordinary data - strings, ints, etc - to and from a config file? Having found that the Bundle parameter for Activity.onCreate() etc is usually null (a feature that's IMHO extremely counter-intuitive) I am therefore obliged to directly read/write non-trivial app data to a file in the private data dir. Indeed the FAQ seems to recommend exactly this. And here's where I start to feel I'm missing something obvious... how on earth do you do it? I can create a nice Bundle, or a Parcel, stuffed with the arrays of ints and strings that I want to write but how does it get to and from the disk? I was expecting a writeToFile(FileOutputStream),method on Bundle or Parcel but neither exist. I see Bundle at least implements toString(), but sadly there is no fromString() to match it.

[android-beginners] Android on FPGA, feasibility issue
Hi all, We are doing our masters project at IITD, our supervisor has asked us to consider getting the Andoid OS working on FPGA. This project is very important for us as it has 18 credits out of total 61. So we want to be very sure that we would get this done. These are the questions we'll like to ask. Has someone already ported Android on FPGA? Is there a project people are working on with this as their aim? Android works on Linux with Java running on top of it. To get this to work we would first need Linux to work on FPGA with Graphics and also have Java running on top of it. How is this supposed to be done? Has it been done? If I download the Android OS and build on linux 32 bit. Will it work on x86 architecture (for testing purposes)? On the webpage http://source.android.com/download this line is written To build the Android files in a Mac OS environment, you need an Intel/ x86 machine. The Android build system and tools do not support the obsolete PowerPC architecture. Is the same statement valid even if build in ubuntu linux environment? How much time/effort you people think would be required? There are 2 people (Tapas and Ashish) doing the same project which will go on for about an year? Can we get some papers published for our work?

[android-beginners] Bug in Notepadv3 Tutorial
Hi, I have found a bug in the NoteEdit class. The bug lies in the "outState.putLong(NotesDbAdapter.KEY_ROWID, mRowId);" statement in onSaveInstanceState() method. When a new note is created the mRowId is null. If the application is terminated while user is editing a new note, an uncaught NullPointerException will be thrown because an null parameter is passed into outStat.putLong(). To reproduce the bug: 1. Launch Notepadv3 application. 2. Press the "Menu" key. 3. Select "Add Note". 4. Press the "Home" key to terminate application. I think it can be solved by replacing the statement with saveState(). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Parallel arrays or Array of objects?
Hello, and my apologies if this topic has been covered (I didn't find anything from a handful of searches on Android Beginners!). I read in the "Designing for Performance" guide that: "An array of ints is a much better than an array of Integers, but this also generalizes to the fact that two parallel arrays of ints are also a lot more efficient than an array of (int,int) objects. The same goes for any combination of primitive types." Which makes sense to me. However, in my particular project, I receive a JSON object (hash) of data from the web, and need to display this data on an Android phone in key-sorted order. In this case, I can't think of an easy way to maintain parallelism between the two arrays while sorting the keys alphabetically. I could reinvent the wheel and write a search which modifies both arrays at once I guess, but that sets off red flags for me that there must be a better way. Should I just take the hit and implement this as a single array of (String, int) (aka key, value) objects? Is there a way that I can somehow sort the keys prior to building my array from the JSON hash object? Any ideas or input would be much appreciated! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Re: How to connect external webcam
I recall reading that one of the things that needs to be done before Android can be seen as a solution for netbooks is the USB host, so I guess you can't connect anything to it.

[android-beginners] Using google's "my maps" functionality
Hi fellow Androids, I was experimenting with creating a google map on my home pc. Then i thought how great it would be if i could load the map inside of an Android app using mapview. So after i created my map, i obtained the url for it: http://maps.google.com/maps/ms?ie=UTF8&hl=en&msa=0&msid=102756143133832946606.00046a429454dfe5bb393&z=17 This works just fine if i load it within a browser, but my question is how can i load a pre-created google map within a mapview? What would be the process involved? I was kinda hoping there'd be a parameter in the mapview viewgroup which would take a google map URL, but no such luck. I'm beginning to suspect that i'd need to programmatically hit the googlemaps api, load up my pre-created map, find out all the placeholders, lines etc, and then manually add them into my mapview myself. Is this the case? Any help is greatly appreciated. Theo --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Re: Parallel arrays or Array of objects?
As it turns out, there definitely was something really simple that I was overlooking. Rather than mess with parallel arrays, or a String, int datatype, I can just String together the String and the int from my hash to begin with! In hindsight it ended up being embarrassingly simple, but I figured I'd leave record of my mistake in case it helps somebody else out!

[android-beginners] Best practice for polling a remote resource periodically
Hi All, I'm starting to write an app that will periodically poll an HTTP resource and use the data to update a View. My initial thought process on how this will work is that on application startup, my activity will spawn a worker thread that will maintain an object model of the data and update it as necessary. Ideally this thread would publish back to the UI thread that the data has changed and the UI thread would read the object model and update the view. I'm not too familiar with Android's architecture to support threading and messaging between threads, so I was wondering if there was a good up to date tutorial etc. that someone could point me to. Thanks, Dave ps. In the past I've used AsyncTask but i don't think it will meet my requirements as the UI thread would need to maintain a timer to kick off an AsyncTask. Ideally I'd like to isolate these two parts of the application as much as possible. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

First, threads aren't usually really objects, insofar as "threads" don't manage models -- objects do. The object that manages your local copy of the remote data can have its timer (TimerTask, AlarmManager with a service, Handler#postDelayed, etc.) and use AsyncTask for the actual work once the timer triggers. You can use encapsulation to maintain your isolation between the UI and the timer/thread object. If you're fairly certain you will have a single activity, I would: -- Create a class to handle your timer/thread work, plus the AsyncTask implementation -- Put a Handler object in your activity -- Pass the Handler to the timer/thread object in its constructor, along with whatever sorts of listeners you're going to use to notify the UI of changed data -- Call postDelayed() on the Handler, where the Runnable supplied to postDelayed() schedules the next timer tick (via another call to postDelayed()) and kicks off an AsyncTask to do the heavy lifting -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Android App Developer Training: http://commonsware.com/training.html --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] [system crash : wifi and bluetooth]
Hi All:
When I open wifi and bluetooth, the system is workable. But when I
reboot the system and don't turn off either wifi or bluetooth before
rebooting, I find the system would be crash in the rebooting process.
However, It only happens on both wifi and bluetooth to be open.
Does somebody have any idea? The below is my error log.
