Android :: Putting Serializable Classes Into SQL?
May 4, 2010I have a bunch of objects that implement Serializable that I want to store in a SQL database.
I have two questions:
Is there a way to serialize the object directly into the database. Is that the best way to do it or should I Write the object out to a formatting String and put it in the database that way and then parse it back out
Write each member to the database with a field that is unique to each object.
Android :: Parcelable String Array
Oct 26, 2010I have
ArrayList<String> ids = ArrayList<String>();
What would be the cleanest way to make it Parceleable? Apparently String itself is not parcelable, so Parcel.writeList(ids) is not working.I was thinking to either parcelize ArrayList<Uri> or put array contents into a Bundle.
Android :: Serializable Object Put Into Intent
Oct 10, 2009I have problem with a class i want to pass in an intent by putting it into the putExtras()
Its serializable and the code looks like this:
CODE:................
The problem is, that y now is an ArrayList and no longer an ObjectB so i cant cast it..
if i change the code to

It works fine.
Android :: ClassNotFoundException When Using Custom Parcelable
Feb 21, 2010I use a custom Parcelable to carry some data to a BroadcastReceiver. Here is what i do:
I register my intent and set the extra Parcelable on it along with an extra classloader (intent.setExtraClassLoader(..)). Next i schedule the execution of the broadcast via an AlarmManager.
So when the AlarmManager fires it looks at my intent with its parcel which it can not process since it doesn't use the supplied classloader (as it seams).
I think the classloader gets lost when Inten.fillIn copys the intent to a new one (see stack trace).
CODE:.......................
Android :: Bundles And Serializable Objects - What Is Actually Stored?
Mar 24, 2009was wondering about the behavior of Bundles and serializable objects. If I put a serializable object into a bundle, what is serialized then, the reference to the object or the object itself? I always assumed that the object itself would be serialized to a byte stream when calling putExtra() and re-created from that representation when calling getSerializableExtra(), but I recently stumbled upon a piece of code that put an entire view into a Bundle in thread A, retrieved it from that bundle in thread B, performed a modification on it and this modification actually became visible. This can only happen if the reference to that view was stored, not the view itself, right? Otherwise, the modification had been applied to a copy of that view and would be meaningless.

View 4 Replies View RelatedAndroid :: Why Is Parcelable Object Null In Receiving Activity?
Aug 16, 2010I am following the Parcelable example in the Android developer guide with the intention of having a more complex object that I send to different activities. Right now, my class is a wrapper of a String member. If I put the object in the intent and read it back from the Intent it reads as expected, however, on the receiver side, it is always null-pointer.
View 1 Replies View RelatedAndroid :: Serializable Object In Intent Returning As String
Jun 16, 2010In my application, I am trying to pass a serializable object through an intent to another activity. The intent is not entirely created by me, it is created and passed through a search suggestion.
In the content provider for the search suggestion, the object is created and placed in the SUGGEST_COLUMN_INTENT_EXTRA_DATA column of the MatrixCursor. However, when in the receiving activity I call getIntent().getSerializableExtra(SearchManager.EXTRA_DATA_KEY), the returned object is of type String and I cannot cast it into the original object class.
I tried making a parcelable wrapper for my object that calls out.writeSerializable(...) and use that instead but the same thing happened.
The string that is returned is like a generic Object toString(), i.e. com.foo.yak.MyAwesomeClass@4350058, so I'm assuming that toString() is being called somewhere where I have no control.
Some of my code
CODE:.........
This is in the activity that receives the search suggestion:

Android :: How To Use Parcelable - If Class Requires Additional Parameters In Constructor
May 20, 2010I'm trying to create class with generics that will have ability to serialize its state using Parcelable interface.
The problem is that class has to contain constructor with single parameter - Parcel, but in my case I need to create class with additional parameters.
Besides, Parcelable.Creator doesn't allow to use generics.
Here is an example:
public class Sample<T> { ...
public Sample(Context ctx, SomeInterface iface, Parcel parcel) {...}
...}
What is the best practice to do it?

Aug 18, 2010What is the difference between these two backup solutions? I am rooted now with Clockwork Recovery installed via ROM Manager, and I have successfully created a "nandroid" backup with Clockwork.
Now, many that have Clockwork also use Titanium Backup for root users. What is the advantage of using Titanium, or does each backup method serve different purposes?
Is it that the nandroid backups can only be used on the same device on which it was created, and Titanium can be used when migrating to a new and different device in order to preserve app data?

View 2 Replies View RelatedAndroid :: Difference In Traceview Time
Sep 24, 2010I'm usign starMethodTrace() and stopmethodTtrace() to get trace data to use on traceview. Everything seems to work fine. I test my app for 50 (real world) seconds having two important events after 15 and 45 seconds from start tracing. However, when analyzing the traceview's timeline I found the total tracetime is only 1.068,964 (msec). My two events are displayed as they were occurred at time 257,743 msec and 642,654 msec. This is just about 1 second of total execution time. Why there is this huge difference between real world time and trace view time? May be because I have a lot of idle time? Is there a way to relate the times displayed in the time line with real world time?
