Android : Can I Use Parcel To Clone An Object?
Sep 22, 2010I have a class which has implemented Parcelable. Can I do something like the following to create a new instance of a class?
found this from the following q: http://stackoverflow.com/questions/1626667/how-to-use-parcel-in-android
This is working ok, I can go with this but it is extra code, not sure if there's a shorter way to do it (other than properly implementing a copy constructor...)
Android : Un-parcel A Parcel Without Knowing What Is In It?
Jan 31, 2010I have a published app that triggers after the Android Alarm Clock goes off. I read the Alarm Clock Label and if it matches a user provided label to trigger off of, my app is triggered. This works great.
The problem is that the HTC Sence UI Alarm Clock uses a different Intent and the extras for that Intent contain a Parcel (that contains the alarm label).
I am able to trigger on the HTC Intent and get the Parcel from the extras, but is it possible to extract the Parcel without knowing what is in the Parcel in the first place?

View 7 Replies View RelatedAndroid :: Pass Unparcelable Object Between Activities
Nov 17, 2010I have an Object that I need to be able to pass between Activites. It implements Parcelable and I've written all the code related to that. The problem is that one of the properties of the Object is a Drawable - and really needs to be. Unfortunately, Drawable is neither Parcelable or Serializable. I don't understand how to pass it. The reason for having the Drawable is that I need to cache an Image that I've downloaded from the internet at runtime. I don't want to cache the images on the filesystem, since this would potentially end up using up a lot of space over time. I'm putting the image into a Drawable so that I can easily put it into an ImageView.

Android :: Way To Pass An Object Array To An Activity
Nov 15, 2010I have read posts on passing arrays from and to activities, but I am confused as to how I would do it for my specific case.
I have an array of objects called DaysWeather (a DaysWeather[] array) where the objects have several String attributes as well as a bitmap attribute. I read somewhere that you have to make it serializable or parceable or something, but it seems messy at first glance.
Could someone lead me in the right direction?
Is there a simple way to do this?
Android : Way To Pass A JavaScript Object On Droid?
Feb 12, 2010Is it possible to pass a JavaScript object from JavaScript to Java using addJavascriptInterface()? Something along these lines: var javaScriptObject = {"field1":"string1", "field2":"string2"}; JavaScriptInterface.passObject(javaScriptObject); How would such a call be captured on the Java side? I have no problem setting up the interface to send a string, but when I send an object, I receive null on the Java end.

View 3 Replies View RelatedAndroid :: How To Pass An Object To An Activity Via Intent.putExtra?
Aug 7, 2009I am developing an app that connects to a server. For that connection I created a class Client that maintains info about the connection . My app consists of several Activities and each of that Activity needs access to the Client object to communicate to the server. 1) Can I put somewhere the Client object so that all Acitvities have an access to it? 2) If not I would probably need to pass the object to each Activity via Intent.putExtra(). But putExtra doesn't accept Object as an argument. It only accepts several types like int, long, String etc. So how can I pass an object to another Activity?

Android :: Safely Pass Object References To New Activities?
Dec 8, 2009I'm working on an application that requires non-serializable objects to be passed between Activities. The following page suggests using a HashMap of WeakReferences to accomplish this:
http://developer.android.com/guide/appendix/faq/framework.html
Is this solution safe? I know Activities are completely destroyed and recreated when the screen orientation changes. Couldn't those weakly referenced objects get GCed in the split second when the screen is rotated, since they wouldn't be referenced elsewhere at that point?
Android :: Pass In Object Java Class Embedded In As Parameter
Apr 19, 2010I'm building an android application, which has a list view, and in the list view, a click listener, containing an onItemClick method. So I have something like this:
public class myList extends ListActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
getListView().setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
/* Do something*/
}
}
}
Normally, this works fine. However, many times I find myself needing too preform an application using the outer class as a context. thusfar, I've used: parent.getContext(); to do this, but I would like to know, is that a bad idea? I can't really call: because it's not really a subclass, just an embedded one. So is there any better way, or is that considered cosure? Also, if it is the right way, what should I do if the embedded method doesn't have a parameter to get the outside class?

View 3 Replies View RelatedAndroid : Get A Parcel From Intent's Extras?
Sep 16, 2010I've implemented parcelable on a class of mine per the doc instructions, works fine: code...
but I haven't implemented a copy constructor. However, the createFromParcel() method which I did implement is almost like a copy constructor. I'm wondering if I can use it make a copy, but I can't figure out how to get a Parcel instance from the intent extras:
MyParcelable mp2 = MyParcelable.CREATOR.createFromParcel(getIntent().getExtras().getParcelable("key"));// ? just need a parcel ?
it's not the greatest idea, just wondering if it's possible to avoid making another method for my class which will almost be identical to what's already implemented for the Parcelable interface..

View 2 Replies View RelatedAndroid : Is Parcel's Data Size Platform Dependent?
Sep 27, 2010According to the API doc, Android seems to support for changing the data size of Parcel container. And there is no notice limiting the size of Parcel. The document is here http://developer.android.com/reference/android/os/Parcel.html#setData...()
On the other hand, when our developers are doing some tests on this, the size is dependent on the platform and devices.
So i just wonder whether there is any limit on the data size of Parcel. At least this information should be mentioned in the API document.

View 1 Replies View RelatedAndroid :: Writing Arrays Of Parcelables To Parcel In Android
Dec 11, 2009I'm trying to write an array of objects that implement Parcelable into a Parcel using writeParcelableArray.The objects I'm trying to write are defined (as you'd expect) as:public class Arrival implements Parcelable {All the right stuff in here this class compiles and acts fine And I'm trying to write them into a `Parcel' with: @Override public void writeToParcel(Parcel dest, int flags) I completely don't understand this error message. Parcelable is an interface (not a class) so you can't extend it. Anyone have any ideas? UPDATE: I'm having basically the same problem when putting an ArrayList of Parcelables into an Intent:Intent i = new Intent();i.putParcelableArrayListExtra("locations", (ArrayList< Location> ) locations);Yields: The method putParcelableArrayListExtra(String, ArrayList< ? extends Parcelable >) in the type Intent is not applicable for the arguments (String, ArrayList< Location >)This may be because Location was the class I was working on above (that wraps the Arrivals), but I don't think so.

This is the android URI returned by android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI content://media/external/images/media/3
When I try to construct a java URI object from this object, I get an IllegalArgumentException with the exception description Expected file scheme in URI: content://media/external/images/media/3 whereas the android URI shows the scheme as content
Never found a solution for the original question. But if you want the byte stream of an image in the pictures gallery, this piece of code will do that.
