[android-developers] Re: AsyncTask in Android 4.0

[Emanuele Ricci]

Hi Michael do you have some good alternative to the current AsyncTask 
implementation?

Anyway the real big big big problem is for the 3rd party library or SDK 
that my project is currently used.
I'm using some ads SDK and I'm pretty sure that they are using also 
AsyncTask in the "normal" way so I'm really afraid that their asynctasks 
will block mine for the "serial problem" we were discussing.

[android-developers] How to join Android Media query search suggest

[Emanuele Ricci]

 

I will explain a little more my scenario.

I'm extending the default music player with other features and 
informations. So I've a sqlite db where I store those informations in 
addiction of the MediaStore.

I want to extend the default search suggestions (for audio) with 
suggestions from my databse.

How can I do it?

I think that the 2 easiest ways are to:

   - Join the default search suggestion to add my results
   - Or understand where Android is doing the dirty work and merge the 
   actual cursor with mine. 

For the second solution I need to know where is the source code of those 
functions. I really prefear the second solution because I also want to 
learn how to do that things!

Thank you very much.

Putting the bitmap reference in the convertview tag and retrieve the

[android-developers] listview adapter. Recycle bitmap

[emanuele]

Hello guys.. that s my baseAdapter getview implmentation:

@Override
public View getView(int position, View convertView, ViewGroup parent)
{

int type = getItemViewType(position);
if (convertView == null) {
switch (type) {
case TYPE_BIG_NEWS:
convertView = 
mInflater.inflate(R.layout.big_news, null);
break;
case TYPE_NORMAL_NEWS:
convertView = 
mInflater.inflate(R.layout.normal_news, null);
break;
default:
break;
}
}

ImageView thumb = (ImageView)
convertView.findViewById(R.id.thumbId);




File f = null;
if (filename != null)
f = mFileCache.getFile(i.newsKey, filename);
if (f == null) {
if (mGetThumbsThread != null && filename != 
null) {
Log.i(TAG, "cache miss");
thumbLinks.offer(new 
ThumbRequest(i.newsKey, i.thumbLink,
i.thumbName));
mGetThumbsThread.signal();
}
thumb.setImageResource(placeHolder);
} else {
Log.i(TAG,
"file bitmap cached: " + 
f.getName() + " size: " + f.length() /
1024);
bitmap = 
BitmapFactory.decodeFile(f.getAbsolutePath());
thumb.setImageBitmap(bitmap);
}

return convertView;
}


Every row is compound of text and an ImageView. Is there any chance to
recycle the bitmap I use in the getView?

[android-developers] Memory retained by fragments android

[emanuele]

Hello there, could somebody explain me when the memory retained by
fragment is released?
For instance, If I have a fragment into the back stack and i call
popBackStack with the inclusive flag, all the resource allocate with
the fragment would be freed? What If I call remove on transaction
instead?

thanks in advance

[android-developers] ListFragment addHeaderView and addFooterView issue

[emanuele]

hello there,

I ve two ListFragments maganed by a tabhost. Firt time I switch
between tab all is alright. The headerView is correctly added. The
second time I switch between fragment I get this execption:

10-05 15:15:01.585: ERROR/AndroidRuntime(23263):

and the app crashes. The code I use to add the header view follows:


   @Override
public void onActivityCreated(Bundle arg0) {
super.onActivityCreated(arg0);
getListView().setOnScrollListener(this);
getListView().addHeaderView(searchBox);
setListAdapter(mAdapter);
}


I manage to fix (??) setting the list adapter to null befor adding the
header view but it does not seems a good thing to me.


   @Override
public void onActivityCreated(Bundle arg0) {
super.onActivityCreated(arg0);
 setListAdapter(null);
   getListView().setOnScrollListener(this);
getListView().addHeaderView(searchBox);
setListAdapter(mAdapter);
}



Adding footer instead I have the following crash:


10-09 18:45:13.866: ERROR/AndroidRuntime(18191):

in order to add the footer I run the following snippet

 @Override
public void onActivityCreated(Bundle arg0) {
super.onActivityCreated(arg0);
 setListAdapter(null);
   getListView().setOnScrollListener(this);
getListView().addHeaderView(searchBox);
if (footer != null) {

getListView().addFooterView(footer);
}
setListAdapter(mAdapter);
}


What am I doing wrong?

[android-developers] Fragment Rotation and WebView

[emanuele]

Hello guys, in my design I have a FragmentActivity (FA) with a
ListFragment (LF). When user clicks on an item, a new fragment
composed of a webview with some information is shown, when a the
mobile is in portrait and a FragmentDialog is shown when the mobile is
in landscape. After some times I go through portrait to landscape, I
analyzed the memory with the eclipse MAT, and found multiple instance
of my FragmentActivity. It seems related to the WebView, since if I no
longer use the webview the issue disappear. So my questions are:

1. Best way to manage the rotation
2. what s wrong with the webview?

Note: I want to rotate only the fragment but not the ListFragment

[android-developers] popbackstack in fragmetns

[emanuele]

Hello there, in my design I ve 4 ListFragments managed by a
FrameActivity with tabhosts. For every ListFragment  i keep its
history (addToBackStack(String name)). Switching beetwen ListFragment
I want to clear the tab content and display the content of the new
ListFragment. In the FrameActivity I tried to achive with
popBackStack(String name, POP_BACK_STACK_INCLUSIVE), but it seems like
the first entry of the ListFragment I am popping back is added to a
transaction and executed at commit. Is this the correct way to achive
the behaviour  I need?

Thanks

[android-developers] how start fragments

[emanuele]

Hello guys, I ve the following scenario: A fragmentActivity which
manage four different ListFragment. Every ListFragment can launch
different kind of fragments and these could launch others fragments.
What I need to understand is who can or cannot launch fragments. Is
responsability of the FragmentActivity or could be the ListFragment,
when onListItemClick is fired, for instance?

Re: [android-developers] OpenGL Samsung Galaxy S2 S II Problem With Rotation

[emanuele padula]

Thank you Christopher. I'll do some test regarding the mipmapping, but i'm
not sure that it will work. Thank you for you suggestion.

Re: [android-developers] Re: SQLite complex query and handling results

I was talking about ORM in general.
IOSched is not a so little application so maybe creating an ORM tool to
integrate in Android was not a so bad idea :)

R: Re: [android-developers] Re: SQLite complex query and handling results

[Emanuele Ricci]

SELECT posts.post_id, posts.post_title, 
GROUP_CONCAT(categories.category_name) AS categories_name, 
GROUP_CONCAT(categories.category_id) AS categories_id, 
GROUP_CONCAT(tags.tag_id) AS tags_id, GROUP_CONCAT(tags.tag_name) AS 
tags_name FROM posts INNER JOIN posts_categories ON 
posts_categories.post_id=posts.post_id INNER JOIN categories ON 
posts_categories.category_id=categories.category_id INNER JOIN posts_tags ON 
posts_tags.post_id=posts.post_id INNER JOIN tags ON 
posts_tags.tag_id=tags.tag_id;

This doesn't work if I have 0 tag for a post or 0 categor for a post.
Also it display only 1 row with all categories ( I have removed tags part to 
make the example ).

I'm not saying that you are wrong because I've to learn the differences 
between them, I'm only exposing results :)

Thank you for your advice, I will take a look at it.

Ok I solved it:

SELECT posts.post_id, posts.post_title,
GROUP_CONCAT(categories.category_name) AS categories_name,
GROUP_CONCAT(categories.category_id) AS categories_id,
GROUP_CONCAT(tags.tag_id) AS tags_id, GROUP_CONCAT(tags.tag_name) AS

posts_categories.category_id=categories.category_id LEFT OUTER JOIN
posts_tags ON posts_tags.post_id=posts.post_id LEFT OUTER JOIN tags ON
posts_tags.tag_id=tags.tag_id GROUP BY posts.post_id;

Thank you very much for the hint of GROUP_CONCAT!!!

Anyway I always think that Android need something to bind Object to DB like
in web frameworks :)

Re: [android-developers] Re: SQLite complex query and handling results

[Emanuele Ricci]

This is what I get:
http://blobs.ge.tt/8tYJKz4/concat.png?sig=-TB4nxfSNqs5AchU5rFsughxje1g4iFms8w

Only a row :/ Am I wrong?
Anyway I think that this solution doesn't fit the real scenario. I
semplified a bit my query.

In the real usage I want to select:

SELECT posts.post_id, posts.post_title, categories.category_id,
categories.category_name, tags.tag_id, tags.tag_name FROM posts LEFT OUTER
JOIN posts_categories ON posts_categories.post_id=posts.post_id LEFT OUTER
JOIN categories ON posts_categories.category_id=categories.category_id LEFT
OUTER JOIN posts_tags ON posts_tags.post_id=posts.post_id LEFT OUTER JOIN
tags ON posts_tags.tag_id=tags.tag_id;

Because I have also to JOIN tags table :)

Re: [android-developers] Re: SQLite complex query and handling results

[Emanuele Ricci]

Maybe you don't understand. I'll make an example

TABLE POSTS:

POST_ID | POST_TITLE

1   | My first post
2   | My second post! Yay!

TABLE CATEGORIES

CAT_ID  | CATEGORY_TITLE

1  | General
2  | Blog
3  | Sport
4  | Comic

TABLE POSTS_CATEGORIES

POST_ID | CATEGORY_ID

1 | 1
1 | 2
1 | 3
2 | 2
2 | 4

What does it mean? That "My first post" have 3 categories: General, Blog,
Sport and "My second post! Yay!" have 2 categories: Sport and Comic

So with this query (where I want to load ALL POST with their categories):

SELECT posts.post_id, posts.post_title, categories.category_name FROM posts
LEFT OUTER JOIN posts_categories ON posts_categories.post_id=posts.post_id
LEFT OUTER JOIN categories ON
posts_categories.category_id=categories.category_id;

I'll get this results:

1 | My first post | General
1 | My first post | Blog
1 | My first post | Sport
2 | My second post! Yay! | Blog
2 | My second post! Yay! | Comic

And I think this is the only efficent way to load all my data using only 1
query to optimize it.
But: how can I handle all data in my ListFragment with my own Adapter that
extend CursorAdapter?

I cannot display all 5 post because as you can see we have repetitions.

[android-developers] SQLite complex query and handling results

[Emanuele Ricci]

Good evening ( for me ), I'm Emanuele a young android developer. 
I want to share with you my problem because I'm not finding a good solution.

I've 3 tables (in reality 5)

posts
categories
posts_categories

to create the many-to-many relation between posts and categories

I've created a ListFragment to show all my posts with their categories.

So I've created this query ( I don't write all the code [image: :)] )

SELECT posts._id, posts.post_title, categories.category_name FROM posts LEFT 
OUTER JOIN posts_categories ON posts_categories.post_id=posts.post_id LEFT 
OUTER JOIN categories ON 
posts_categories.category_id=categories.category_id;

So if I have 2 post with 2 category each that query will return 4 records. 
Am I wrong?
So in my Cursor I have 4 record but what I really need is to collect datas 
from the cursor and display only what I really need.

In this case I cannot use a CursorAdapter to display my data because it will 
insert 4 item in the ListFragment.

And I don't want to load only post and than for each post load categories 
because if I have 100 posts I will do 1 query to select all posts and 100 
query to select categories.


What can I do? I need an expert advice! Which is the best way to handle this 
situation?
Have you ever faced this problem?

Thank you very much. Emanuele Ricci.

[emanuele]

Hello guys, i was playing with animations (scaleanimation) and I notice a

animation object and try to restart it, the onAnimationEnd callback in

Thanks a lot for the tip. So using this technique the application will
be anyway installed in the device (if I don't specify the
minorSDKVersion in the manifest.xml) even if the device SDK doesn't
have the class I use in the Reflection or wrapper class?

Thanks

[android-developers] Re: ScrollView disappears when the keyboard appears on the screen

[Emanuele]

Solution found. Set "adjustPan" for the "android:windowSoftInputMode"
parameter for the activity in the manifest.

[android-developers] EditText and Virtual Keyboard

[Emanuele Di Saverio]

Hi all,
I was fillding with EditText and handling of events, and I was wondering on
a strange thing:

If you press some of the keys (for example forward slash '/') on the
emulated physical keyboard, the keyevents are called
as usual (onKeydown, the KeyListeners etc).
If I click on the corresponding virtual key on the onscreen virtual
keyboard, all these callbacks do not get called at all!
This is strange, given that If I press other keys like alhpanumerical, the
events are called.

Can someone explain me this behaviour of the EditText component?
Thanks a lot

[android-developers] Log vs Logger

[Emanuele Di Saverio]

Hello all guys,I was taking a peek at Android doc for Log and Logger class.
I see that the common use is to stick to Log.x methods, but I also see some
useful methods on Logger (like log a method entering and exit).

Could you pick me an example of usage of the Logger class? Maybe this thing
should only be used when building custom loggers?

Thanks

-Emanuele
