Re: [android-beginners] Re: Database handling - when do you open and close

[YuviDroid]

mmm I'm not really sure what you are trying to achieve. Exactly, at what
times do you want to open/close the db? The db should stay open while your
application is running? So, even when you switch among activities (yours
activities)?

[android-beginners] Re: Flurry and AppWidgets

[whitemice]

Hi Jake
Assuming you are talking about Android Home Screen Widgets, I had the
same issue which I blogged here:
http://blog.zedray.com/2010/05/01/tracking-a-android-home-screen-widget/

I still haven't gotten a response from Flurry, so I suggest you
consider the Google Analytics API.  While this offers fewer features
relevant for application developers, it does provide a dispatch()
method which allows you to manually workaround the widget life cycle
issue.  Let me know how this works for you.

Regards
Mark

Re: [android-beginners] SQL and SQLite

[Mikey]

SQL is Structured Query Language, a language for writing queries to an RDBMS

SQLite is a lightweight implementation of an RDBMS that runs on Android (among 
other places) and uses SQL to return data.

[android-beginners] Re: SQL and SQLite

[DanH]

Yes, SQL is a "standard" for a database query language and API, and
SQLite is an (open source, portable) implementation of that standard.
Some would quibble about how well SQLite adheres to the standard, but
one can also say the same of most other implementations (there are
lots of "dialects"), and SQLite is something of a de-facto standard.
One nice  thing about it is that a SQLite database is portable between
platforms, meaning, eg, you can construct a database on your PC and
transfer it as a single file to your phone.

On the bad side, SQLite is so "loose" in its standard interpretation
of the standard that a query script for SQLite is nowhere near
guaranteed to run on another SQL implementation.

SQLite is also not that good for really large databases, but you
wouldn't run such a large database on a phone.

[android-beginners] Re: Using SQLite update DB

[DanH]

Just a hint:  SQLite generates some pretty good diagnostic messages.
I'm assuming (I've not used SQLite on Android) that the message info
is in the SQLiteException.  You need to print that out and report the
message when asking for help.

Re: [android-beginners] Re: addContentView obscures events

[Justin Anderson]

What exactly are you trying to accomplish?  Are you trying to get the same
sort of effect that the browser or google maps has with the zoom in/out
buttons (in that they show up on top of the current view)?

The google maps source definitely isn't available, but if the browser source
is then you could see how it is implemented in there by getting at the
source and seeing what is done...

[android-beginners] non-chat bluetooth example

[Affan]

I need to send and receive data from an Android client to a Bluetooth
SPP server on a non-android platform (not decided, but possibly
Arduino with C code).

I am mostly trying to correctly read from the serial iostream provided
by the bluetooth socket and convert that into a Java class (to use as
a structure). while packaging a delimted byte stream is easy, I am not
quite sure about the serial io reading from the io stream (i.e. is
there a maximum byte size it will read? does it split the file sent
from the serial port and i have to manually combine later?).

Now, bit shifting and using something like ByteStream can make it
work, I was wondering if there is a serialization or mashalling stub
code that is already available on Android. Furthermore, the received
(at android) structure can have variable size strings, so
serialization becomes an even greater challenge, if done manually.

An example code doing non-chat (or string based) comms over bluetooth
in SPP (serial port profile) in android would be perfect (some sort of
protocol frames that are exchanged). I have googled this , but either
my google-fu has gone bad, or there just isnt any such example at the
top of search lists.

Re: [android-beginners] Re: Creating a populated sqlite database

Rodney,

Just one more option - write a small Android app to create the database, 
then pull it from the device using "adb pull" and place into the "real"

project as an asset.

[android-beginners] Re: Java Keyword This and Button Listeners.

[Keith Roberts]

 setOnClickListener actually takes the callback method that will be
invoked when the user presses the button interface as an argument, so
it doesn't take a view  Basically you're saying "this" is just a
reference to the current object you're in.  So if you're in a specific
method and you use this, it tells the complier to pass in class
variables not the local ones because the instance of the class would
be outside of the method??  also, if your class contains multiple
instances how does the complier know which one "this" is referring
too?

[android-beginners] Re: Java Keyword This and Button Listeners.

[DanH]

setOnClickListener takes a reference (pointer) to an object as its
argument.  That object must implement the onClick() method.  So when a
click occurs, the onClick method of that object (that specific
instance of that class) is called.  Using "this" just directs that the
onClick method of the current object be used if a click occurs.

Another way to understand "this":

public class MyClass {
 public void myMethod(Object someObj) {
  if (someObj == this) {
   System.out.println("someObj == this");
  }
  else {
   System.out.println("someObj != this");
  }
}

public class MyOtherClass {
  public void doSomething() {
   MyClass theInstance = new MyClass();
   MyClass notTheInstance = new MyClass();
   theInstance ->myMethod(theInstance);  // This will print "=="
   theInstance ->myMethod(notTheInstance);  // This will print "!="
   theInstance ->myMethod(this);  // This will print "!="
  }
}

[android-beginners] Re: Creating a populated sqlite database

[DanH]

Certainly with only 100 rows you could write the SQL script containing
the create table command and 100 insert commands and then use
something like SQLite Expert to execute the script and create the DB.
Or you could just write a straight Java application to execute the
commands and create the DB.  The SQLite file that results in all cases
is "portable".

But for only 100 rows and 3 columns it's hardly worth messing with SQL
-- you can just create an array containing the data and search that,
or load up the data in a HashTable or some such.

[android-beginners] Including libraries in project

[kypriakos]

Hi all,

I managed to compile the imported application (the trick was not to
just
throw the lib directory in the project but to also build a library out
of  the
jars and present that in the project class path). However, I am
noticing
in DDMS (and in debug perspective) when I launch the app that one of
the
threads quits and complains that:
"Failed resolving Lcom/myApp/PeerToPeerAdapter: interface 211 Lnet/
wlib/PeerGen".

I can see the net/lib/PeerGen in the jar files included in the library
that
is in the classpath. Afterall it compiles fine. Why does it complain
at runtime? Doesn't the Android plugin package what it needs in the
dex,
apk and res_ files before it deploys the app in the emulator?
I could not find anything on this in the resources so I am wondering
if
anyone had this issue before - It could be trivial and I am missing
something
very obvious.

Thanks

[android-beginners] Detecting version of Android at runtime

I'm about to implement a hack to work around a bug in Android 2.1. I'd
like that hack to be inactive in 2.2 where the bug is (reportedly)
fixed. How can I test at runtime for the version of Android that the
phone is running? In case anyone is interested, here's the hack:

[android-beginners] The Force Close Error is suddenly back...

[Victoria]

Hi,

I am trying to load videos from my emulated sdcard into my implemented
GridView, it worked fine before, when I used the GridView example from
Google...but now I get a Force close error when I try to open the app.

The entire app works (or rather should work) like this a TabView is
launched that includes 2 tabs (GalleryView.java and main.xml), each
tab loads a GridView (EditGalleryView.java and ShareGalleryView.java).
Before I tried loading videos into the gridView I simply used the
GridView example as starting point. Now on basis of this example I am
trying to load videos into my GridView from the sdcard, which
apparently seems to cause a Force Close Error.

If someone could help me find the problem that's causing this, it
would be great because I really don't know what's wrong now ...
Thanks in Advance

Here is the code I use:

The Manifest.xml:

http://schemas.android.com/apk/res/android";
  package="com.mobilevideoeditor.moved"
  android:versionCode="1"
  android:versionName="1.0">

  }
 
Log.d("EditGalleryView", "vidUris:"+vidUris.length);

Re: [android-beginners] The Force Close Error is suddenly back...

[Kostya Vasilyev]

Victoria,

The cause of this exception appears in logcat:

07-16 19:40:45.124: ERROR/AndroidRuntime(225): Caused by:
java.lang.NullPointerException
07-16 19:40:45.124: ERROR/AndroidRuntime(225): at
com.mobilevideoeditor.moved.EditGalleryView
$VideoAdapter.getCount(EditGalleryView.java:73)

Looks like vidUris is null.

Set a breakpoint and debug - looks like adapter's getCount() gets called 
before the information (vidUris) becomes available.

Re: [android-beginners] Re: Java Keyword This and Button Listeners.

[Justin Anderson]

I would seriously recommend reading up a little more on Object Oriented
programming... The "this" keyword is an extremely basic and extremely
essential concept for OO programming.  It is used in Java, C++, C#, and many
other OO programming languages.  If an OO language doesn't have the "this"
keyword it usually has a different keyword like "self" that means and does
the same thing.

Much of your confusion is a direct result of not understanding the "this"
concept...  Once you understand it, many other things will become much more
clear.

Why are you sorry?

I could tell you how to set a break point. Or I could tell you that simple
Google search lead me to this, where you can find the answer yourself. It's
really that simple.

Alright :) okay I see what you mean now, I guess,  but for most of these
lines I get something like source not found... The JAR of this class file
belongs to container Android 2.1 - update 1 which does not allow
modifications to source attachments on its entries.

Re: [android-beginners] The Force Close Error is suddenly back...

[Kostya Vasilyev]

So far so good, you've successfully hit a breakpoint. Now you need to
inspect variables (Google for Eclipse debugging basics).

Also set a breakpoint whee data is handed over to the adapter, and see which
one gets hit first.

BTW, I think adding "if (vidUris != null)" inside getCount() will fix the
crash for now, but still - learning how to debug and understand what the
code actually does during execution is instrumental to any further
development work you plan on doing.

Re: [android-beginners] The Force Close Error is suddenly back...

[Victoria Busse]

I will definitely read and learn about debugging now...Thanks :)))

The way you said works...

public int getCount() {
//return mThumbIds.length;
   if(vidUris!=null){
 return vidUris.length;}
return 0;
}
...but the videos don't show up, so I still have a problem with retrieving
the videos from the SD card :(

"This exception is thrown when a call to startActivity(Intent)  or one

[android-beginners] Can soundpool be made to play sounds and record them at the same time?

[Traveler]

I am working on an Android app that generates sounds. Is it possible
to generate these sounds and record them at the same time using
soundpool? The opject is to send the recording to another Droid after
the initial sounds are generated with my Droid. Thanks for any advice.

[android-beginners] Re: ActivityNotFoundException and txt files

[Harald]

Is there any way to fix it so that Android know how to open .txt
files, or can I somehow in my code tell Android to use File Editor to
open/edit .txt files.

I do not know what "File Editor" is. If that is some third party text
editor, contact the author to see how to integrate your code with
theirs.

There is no text editor built into Android.

[android-beginners] Re: Including libraries in project

[kypriakos]

So it is fair to say = Android bytecode != 3rd party code bytecode
(particularly
from IBM or SUN or Axis)? So the reason I am not seeing the libraries
(which
otherwise helped me compile my imported app in Eclipse) in the apk
file
is because they are not recognized by the Android platform? Unless I
obtain
the source code for all those libs and try to compile and fix the
millions of
errors that will probably appear, I won't be able to use them? Is that
a fair
statement? Oh o ...

Thanks
