[android-developers] SimpleCursorAdaptor ListView using an TextView and ImageView with over 400+ rows Memory Issues
Is this the best way or are there others? I extend SimpleCursorAdapter and override getView(int position, View convertView, ViewGroup parent) I retrieve my Cursor, inflate my ImageView and TextView, pull the data from the Cursor and populate the TextView and ImageView on the ImageView I store my images in the database as Blob's. When I retrieve my Blob I pull it out as a byte[] and convert it to a Bitmap as below: Bitmap bmp = BitmapFactory.decodeByteArray(img, 0, img.length); Then I set my Bitmap on my ImageView as : iv.setImageBitmap(bmp); Now I can scroll down fine no issues but when I start scrolling back up the list I get major memory issues and sporadic jumping(from when the garbage collection catches up). Can anyone tell me what the best way to accomplish this task would be? Is there a way to recycle the bitmaps that aren't in view and when approaching them pull them and display again? I've searched for months and tried various techniques but I'm at a loss to finding the one that will allow me to accomplish this task.

[android-developers] Re: Unique device id - which one to choose
From what I've read on some other sites retrieving the MAC with the Wifi off will not always return a valid MAC (as in my case) and some devices don't have Wifi at all. One site as an example : http://stackoverflow.com/questions/4468248/unique-id-of-android-device Quoted from that site : You can get MAC address if network-device (Bluetooth etc.) is enabled in the system (turned on). But device may have bluetooth or wi-fi etc. or nothing Seems like possibly using some of the other ID's in conjunction with a user/pass would be the best bet and updating the changes if and when they occur. My application has been out in the market for over a year now and I can definitely say that the ANDROID_ID is NOT unique in a lot of cases.

[android-developers] Re: Unique device id - which one to choose
Using a Hash of all the ID's is most likely the best solution, gather all the ID's, append your own signature if you like (optional) and hash the long concatenation of all the ID's you can gather, I would recommend using SHA. Most likely not all phones will have all available ID's so by using this you can be sure that the ID you're generating is as unique as possible.

[android-developers] Re: Setting up development environment on windows 7
Is your Windows 7 32 or 64bit? Ensure you're using the Oracle JDK should be 1.6.0_23 32bit Not sure installing 64bit will help much either way unless you have a pretty beefy machine, so I would uninstall the 64bit JDK. What path did you install the AndroidSDK to? Did you setup your JAVA_HOME, CLASSPATH and PATH? What version of Eclipse did you download and install? There are a few different versions with different capabilities. I personally use MyEclipse but Eclipse should work just as well. When you go here http://www.eclipse.org/downloads/ You should pick : 32 bit http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/helios/SR1/eclipse-java-helios-SR1-win32.zip Android SDK : http://dl.google.com/android/installer_r08-windows.exe Android Plugin (ensure you read the one on Helios) : How to http://developer.android.com/sdk/eclipse-adt.html#installing Uninstall your applications first to start with a clean system if you prefer it might make it easier. Install the JDK I prefer to install the JDK to c:\java (note no spaces in path) and you don't have to change references later. Install the Android SDK (also make sure no spaces in the path you install it to) Install Eclipse (ensure no spaces in path something like c:\eclipse) Once you're this far you will need to start the Android SDK application SDK Manager.exe, select Settings and checkmark Force https... then select Available Packages and expand the URL in the right window select what you need to develop on (i.e. version of the SDK you want to work with) then once all is selected click on Install Selected at a minimum you will want : The version you select i.e. SDK Platform Android 2.2, API 8, revision 2 Documentation for that version Samples for that version Google API's for that version Usb Driver package (latest one) Market Licensing package (latest one) Once it's all downloaded you can shutdown the program you opened and go over to the Eclipse application to start development, you will need to tell the plugin where the path to your Android SDK folder is in the preferences but that should be all you need to get started.

I would if possible use asymmetric keys. (public/private) I've not used them on Android so you would have to figure out if it's possible, I'm guessing it is since LVL uses that.

It's possible to use CipherInputStream to do on-the-fly decryption while reading data from a file or from the network. Per-application data files located in phone storage are private, and could be used to cache decrypted data.

They think Wow, surely there must be someone to blame for this and someone with the fix. Oh here this task killer allows me to solve my problem. Soon they are probably having more problems than they started, but they don't care because now everytime they get disgruntled they can do something about it. And nobody wants to admit that they are administrating themselves placebos, so feeling like it *is* a valid solution is self reinforcing. That was a bit long winded. But I agree with Kostya, I don' think people downloading task killers from the marketplace show a deficiency in the OS. Only a deficiency in the way people adapt to new things. Obviously the pre-bundled apps that can't be uninstalled are a huge problem. task killers not really being a good solution there, the real solution is root - uninstall.

[android-developers] Re: SQLiteCursor on that has not been deactivated or closed
Disregard, I found the issue.
If in your MediaDbAdapter call you get a Cursor check for null
etc..then pass it and close it from another class then the one in
MediaDbAdapter does not get closed, until the system does it for you.
I changed it to pass the cursor directly from the call and deal with
it in the class that called it instead and it worked, no more errors.

In other words, it's pure coincidence who picked the highest number... If you handled the button press, you should abort the broadcast with abortBroadcast(). Trouble with this handling is, the priorities and abortBroadcast() work fine as long as each app only responds while e.g. something is played. But several users also expect a default player to be launched (or start playing) upon button press, like the default player, so it might happen some app with a higher priority number won't let the intent come through to your app... (I already filed an issue to improve that:http://code.google.com/p/android/issues/detail?id=7772 - no response so far...) In the onReceive, you can get the button event with KeyEvent key = (KeyEvent) intent.getParcelableExtra(Intent.EXTRA_KEY_EVENT); key.getKeyAction() tells you whether the button was released or pressed, key.getKeyCode() tells which button. The values are documented and pretty self explaining, like KeyEvent.ACTION_DOWN or KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE. Regarding press and release, keep in mind several headsets do own processing which prevents this (like e.g. closing the connection or sending stop on long press on play/pause) or simply send both at once when the key is pressed or released. Also, some BT drivers are a bit unreliable in that regard... If you want to handle single button cable headsets as well, also regard the key code KEYCODE_HEADSETHOOK. btw: HTC Hero doesn't implement this standard, it needs a workaround app. HTH, Mirko -- You received this message because you are subscribed to the Google Groups Android Developers group.

It seems that if each Activity has:

this would be wasteful, assuming there would be N SQLiteDatabase

One could go about making a singleton, but who would be responsible
for closing the database when the application terminates?
Would it be best to extend the android.app.Application class and hook
into the onTerminate() to close the database?
Taking a look at NotePadv3Solution, I can't find where it closes the
database - and that is a pretty straightforward example.

What I did (which may not be the best solution is to call the
db.close() in onPause() method and call the db.open() in any

Be aware that during the activity creation both onCreate() and
onResume() methods are called, so you need to check the db is not
opened yet.
Hope this helps,

HttpsURLConnection.setDefaultSSLSocketFactory(context.getSocketFactory());

2. Before Establishing your connection over SSL call your Fake Trust
manager above like this:
_FakeX509TrustManager.allowAllSSL();
3. Establish your HTTPS connection
HttpsURLConnection con = (HttpsURLConnection) new URL(https://
www.somewebsite.com).openConnection();
con.setRequestMethod(POST);
con.setRequestProperty(Content-Type, application/x-www-form-
urlencoded);
con.setRequestProperty(Content-Length,
+Integer.toString(urlParameters.getBytes().length));
con.setRequestProperty(Content-Language, en-US);
con.setRequestProperty(Connection, close);
con.setUseCaches (false);
con.setDoOutput(true);
con.setDoInput(true);
//Send request
DataOutputStream wr = new DataOutputStream(con.getOutputStream());
wr.writeBytes(urlParameters);
wr.flush();
wr.close();
int statusCode = ((HttpURLConnection) con).getResponseCode();
con.disconnect();

Hi all,
Trying to get HTTPS working with the HttpClient. I can't seem to find
an example anywhere that works for me. Basically, I want my client to
accept any certificate (because I'm only ever pointing to one server)
but I keep getting a javax.net.ssl.SSLException: Not trusted server
certificate exception. So this is what I have:
public void connect() throws A_WHOLE_BUNCH_OF_EXCEPTIONS {
HttpPost post = new HttpPost(new URI(PROD_URL));
post.setEntity(new StringEntity(BODY));
KeyStore trusted = KeyStore.getInstance(BKS);
trusted.load(null, .toCharArray());
SSLSocketFactory sslf = new SSLSocketFactory(trusted);
sslf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(new Scheme (https, sslf, 443));
SingleClientConnManager cm = new
SingleClientConnManager(post.getParams(), schemeRegistry);
HttpClient client = new DefaultHttpClient(cm, post.getParams());
HttpResponse result = client.execute(post);
}
And here's the error I'm getting:
W/System.err( 901): javax.net.ssl.SSLException: Not trusted

[android-developers] Re: Is there a way to force deletion of User Data on Application upgrade?
So this would get fired when you increment your database version?

If you're trying to create a more robust database, you don't have to
delete the existing one. If you have a class that extends
SQLiteOpenHelper, you can call the following function (this moves data
from current table to temp table to remove whichever columns you don't
specify in the swap string, drops current table, renames temp to
original):
public void onUpgrade(SQLiteDatabase db, int oldVersion, int
newVersion) {
Log.w(TAG, Upgrading database from version + oldVersion
+ to
+ newVersion + , which will drop column_A);
String tempDB = create table temp ( + KEY_ROWID +
integer
primary key autoincrement, + KEY_NAME + text not null;;
db.execSQL(tempDB);
String swap = insert into temp SELECT + KEY_ROWID + , +
KEY_NAME + FROM + DATABASE_TABLE;
db.execSQL(swap);
db.execSQL(DROP TABLE IF EXISTS + DATABASE_TABLE);
db.execSQL(ALTER TABLE temp RENAME TO +
DATABASE_TABLE);
}
If you want to add columns to your existing database, it's even
simpler:
public void onUpgrade(SQLiteDatabase db, int oldVersion, int
newVersion) {
Log.w(TAG, Upgrading database from version + oldVersion
+ to
+ newVersion + , which adds SMS, MMS, Bluetooth,
WiFi);
String ADD_COLUMN = ALTER TABLE + DATABASE_TABLE + ADD
column + KEY_NEWCOLUMN + TEXT NOT NULL DEFAULT \The Default\;;
db.execSQL(ADD_COLUMN);
}
