[android-developers] Re: Adding Views into layouts
I have an app in the market right now that uses a custom designed tab bar at the bottom of the screen and a relative layout at the top that acts as an iframe, so this is very doable. In my app I used the LocalActivityManager to load the requested activity and then extract it's main layout, like this: [code] LocalActivityManager manager = getLocalActivityManager(); Intent preloader = new Intent(com.pkg.Foo); View childView = manager.startActivity(preloader.getAction(), preloader.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView(); frame.removeAllViews(); frame.addView(childView); [/code] Each of the buttons in the tab bar calls to a loading function with the requested Activity name and options like ViewFlipper index or other startup options. After you add the childView to the frame, you can also do something like this to animate in the view. [code] childView.startAnimation(slideLeftAnimation); [/code] The only problem with this approach is that LocalActivityManager has been deprecated as if this month in favor of Fragments and the FragmentManager. So you might want to look into both options and see what works best for your users and app needs. If you look at the demos over at android.com there is a tab example using Fragments.

What I am attempting to do is create a View object and inflate the layout I want into the View Object. Is this the correct approach? (by the way the reason I can not use the tabhost is because the client needs a scrolling tabbar so they can have 10 options on the tab bar, so I have implemented a scrollview containing buttons for the tabbar) The structure will be an array of Views each attached to one of the buttons in the scrollView. When selected the View object (if not already populated) will populate using inflate then become visible. Am I close? Is this the wrong approach? Thanks in advance for any assistance.

Pattern pattern =
Pattern.compile(emailPattern,Pattern.CASE_INSENSITIVE);

return matcher.matches();
}

[android-developers] Re: NullPointerException on displaying ImageView of a bitmap
What is specifically happening in your onCreate method at line 62?
That's where the null exception is coming from.
Also, you might want to use the BitmapFactory.Options to help in image
creation. You can easily tweak the options to get image dimensions
without having to create the actual bitmap (see inJustDecodeBounds)
and you can adjust the sample size to put less memory strain on your
application. Try this:
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 2;
options.inTempStorage = new byte[16*1024];
options.inJustDecodeBounds = false;
Bitmap b = BitmapFactory.decodeStream(inputStream,null,options);
Then test b to make sure it isn't null before loading it into your
ImageView.

[android-developers] Re: Non-full screen Activity in Honeycomb?
In the Android activity stack there can only be one app running in the foreground (see this http://goo.gl/WyZOx) so this idea won't work as you might be envisioning it. You could modify the UI of your app so that the window and all backgrounds are transparent, but this would only show you the wallpaper and shortcuts below, no interaction would be possible. If you need to run multiple activities at the same time, you might want to look into using a LocalActivityManager to load activities, pull their main view, and load that into a layout. This would be similar to using an iframe in HTML something like this: LocalActivityManager manager = getLocalActivityManager(); Intent preloader = new Intent(com.pkg.Foo); View childView = manager.startActivity(preloader.getAction(), preloader.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView(); frame.removeAllViews(); frame.addView(childView); frame would be some kind of Linear or RelativeLayout that you could then add a child view to.

How big are the images you're trying to load? If you're creating Bitmap objects from your resources then you are very likely running out of memory in the process. Look into BitmapFactory.Options and try increasing the sample size to see if that makes any difference. I would also suggest that you look into ways to pull your tiles from the web instead of storing them on the device. You very rarely see apps in the wild that have a larger footprint than 20mb and some devices like the G1 only have 70mb of storage TOTAL for all apps. So you're basically asking someone to remove everything from their device to load your app. On Aug 23, 6:38 am, Raphael André Bauer raphael.andre.ba...@gmail.com wrote: Hi, I am currently developing a PhoneGap application - but I am pretty sure that my problem is way more related to Android than to PhoneGap. My app consists of a directory assets/www/maps. In this folder is a huge amount of image files that are tiles for a map library. My observation is: When the asset folder contains around 80mb of files, the app works nicely both on the emulator and on my nexus one. When it's larger than 80mb it crashes on both devices. the devises are running 2.3.3 Api level 10 (but it happens on 3.2, too). The error messages are not really helpful (error parsing apk file popup on nexus and cannot read Android Manifest via logcat on emulator). I am really a newbie on Android, so I am a bit lost here. I already tried to increase the partition size of my emulator like that: emulator -avd avd -partition-size 2047 - but this did not help. Any pointers how to continue debugging would be really great. If there are any limits on the amount of files / size of an apk let me know. I am not aware of any limits - and afaik the 50mb limit of Android apps distributed via the Android Market was lifted some time ago. Thanks a lot :) Raphael ps.

It looks like you're attempting to load an image resource from your

// Get the background, which has been compiled to an

If this is not enough I can also post my R file and the Manifest.

[android-developers] Re: Facebook Share Crash in Android application
The Facebook API is pretty well known for errors, bugs, outages, and just random weirdness. I currently have an app that uses Facebook for posting to a users wall and it's not accepting any of the parameters I send like the default message, caption, etc. One day it works.one day it doesn't. You just have to learn to live with it and wrap all of your Facebook code in about ten layers of try/catch statements. Run your app with DDMS open and see which Facebook class/method is causing the problem, then add all the required error checking that the Facebook developers left out, that should at least keep your app from crashing when their API returns garbage.

[android-developers] Re: how to retrieve images from a sql database?
I'm not sure why you wouldn't have access to the MediaStore, it's been available since API level 1. If you really want to try putting the images directly in the database, just Google something like Android SQLite Blob because that's what you'll need to use. I'm sure there are examples out there. Make sure to use BitmapFactory Options when recreating your Bitmaps, otherwise you're probably going to crash the app after creating a few Bitmaps because you've completely run out of memory on the device. Good luck. On Aug 23, 8:59 am, Abhi abhishek.r.sha...@gmail.com wrote: @Ibendlin - Yes, SQLite on device is what I meant. Sorry about the confusion @Drezden - I somehow don't have that option to add images to MediaStore, keeping the file path in the SQLite database.

[android-developers] Re: SQLite: Tables not created onCreate without any error
If possible post a complete class file for your database helper, it's
really hard to know what's happening when you show random parts from
all of your classes.
On Aug 22, 4:07 pm, Nico Balestra nicobales...@gmail.com wrote:
Ok guys.. I've tried and tried in the hope not to be forced to bother you.
but I have to :)
I'm trying to do a simple thing.. creating a DB when my activity first
starts:
@Override
public void onCreate(Bundle savedInstanceState) {
currenciesDB = new CurrenciesDB(this);
currenciesDB.open();
}
then in my CurrenciesDB constructor/open:
public CurrenciesDB(Context mCtx) {
this.ctx = mCtx;}
public CurrenciesDB open() throws SQLException {
this.dbHelper = new CurrencyStorageHelper(this.ctx);
this.db = dbHelper.getWritableDatabase();
return this;
}
and, as you might reckon, my CurrencyStorageHelper class extends the
SQLOpenHelper class and specifically:
public CurrencyStorageHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
@Override
public void onOpen(SQLiteDatabase db) {
super.onOpen(db);
Log.d(TAG, Opening the database... + db.getPath() + version +
db.getVersion());
db.setLockingEnabled(true);}
@Override
public void onCreate(SQLiteDatabase database) {
database.execSQL(DATABASE_CREATE_1);
Log.d(TAG, Creating table... + DATABASE_CREATE_2);
database.execSQL(DATABASE_CREATE_2);
Log.d(TAG, Creating table... + DATABASE_CREATE_3);
database.execSQL(DATABASE_CREATE_3);
insertDefinitions(database);
insertInitialCurrencies(database);
}
What is happening here is that despite launcing the CREATE TABLE
statements, nothing gets created on the database. After those statements I
even insert records using SQLiteDatabase.insert. But nothing happens.. no
expections and no records get created.
Afterward, when I try to query the DB, I get an option saying that the table
I'm trying to query doesn't (obviously) exists.
I'm not a newbie developer and I've tried to debug my app as much as I
can/know but I have only these clues:
1. During the debug process, the instance of SQLiteDatabase has a
mStrackTrace private attribute set to DatabaseObjectNotClosedException, but
obviously no cursor has been opened.. yet.
2. The db version gets set to zero :(
3. Same behaviour using the Emulator and my Samsunga Galaxy S2 2.3.3 (hence
no wrong configuration of the emulator).
If you had patient to go through the entire email I hope you have even one
single clue on why this is happening (maybe you experienced the same
problem?? ) !!
Log.d(Nico, THANK YOU);
