Does no one perform these types of backups or am I asking the wrong
question?

[android-developers] Re: Best Application Data Backup solution?

[gcstang]

I know there are solutions such as :
Amazon S3
Google Storage
Sending data to my own server
etc...

What I'm wondering is what is the implementations that have been tried
and are working for others?

[android-developers] Best Application Data Backup solution?

[gcstang]

What is the best solution to integrate backup, external to the device
for an Android application?

Ideally the solution will be cheap, integrate easily with an existing
application and will be seamless to the clients.

I know Google Backup is limited so most likely it will not work, but
there has to be other solutions.

Backup per client will be roughly 5-10MB in size.

Thank you in advance.

[android-developers] SimpleCursorAdaptor ListView using an TextView and ImageView with over 400+ rows Memory Issues

[gcstang]

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.

Thank you in advance.

[gcstang]

Thank you for the link but, the layout has changed since that document
lists a section for "Publishing Options", "Locations" but it looks
like that was removed and replaced with "Content Rating" and
"Pricing".

If I remove the country from the pricing by unchecking is that suppose
to do the same thing?

[android-developers] Re: Unique device id - which one to choose

[gcstang]

>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

[gcstang]

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

[gcstang]

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) : 
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.

Good luck

[android-developers] error code 5: database is locked

[gcstang]

Has anyone encountered this and is there a solution to work around it?

I'm creating a Thread and in that thread I open a database connection
using the DBHelper, perform an update on a field in my database and
close it. I create a separate one in the Thread because if the View is
closed the global one for that view is closed, causing my Thread
update to throw an error.

The thread is in a View, that also has it's own instance of the
DBHelper and
opens the database onCreate
closes it onPause
opens it onResume
closes it onDestroy

The instance in my Thread is throwing this but not all the time :error
code 5: database is locked

Is there a known practice I should implement so I don't get this error?

[android-developers] Re: Does App size increase after upload to the And. market?

[gcstang]

I've also seen a decent increase in size upon install, not just from
the market but on a local install the original apk is about 800kb and
installed it's 1.37MB, almost double and I'm using LVL with
obfuscation.

Any way to make this smaller?

[android-developers] Re: XML encryption

[gcstang]

If you encrypt on the phone side with a known pass (assuming your
using symmetric keys) then all the hacker has to do is find your
password ( and salt if you use one) you used to create it and decrypt
it.

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.

[android-developers] Re: Android Market Licensing Service

[gcstang]

Are there any examples of how you implemented it that you're willing
to share?

Even psuedocode would be helpful as an example:

Copied java files 1,2,3 into my project as a pkg
Implemented methods A,B,C
Added X of LVL to onCreate of my main point of access on the
application and did X,Y,Z etc...
if return of G fails I did D to exit my application

Or do you have anything you used online that could take you through it
step by step, the blog post is a bit over whelming to someone just
starting and since you have successfully implemented it I think it
would be of great help to the community and myself to know the proper
way to implement the procedure you used.

If you can't I understand but it would be helpful if you could.

Thank you,

You're welcome, you may also want this if you plan on targeting
devices with Android prior to 2.2

Add this line before you start initializing anything (this bug is
documented in the forum but not easy to find, otherwise you see that
every other response will not be returned properly, it doesn't hurt to
leave it for all versions):

System.setProperty("http.keepAlive", "false");

[android-developers] Re: back_key implementation

[gcstang]

You can also use this so that C is on the top instead of B so when you
click back it will go to A if you launch C from B :

On your Intent set it so the Activity you're launching is on Top which
means B will be removed from the previous position :

In B where you launch C add this flag :

Intent i;
i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

[android-developers] Re: JDOM in Android 2.1 or earlier

[gcstang]

Just my 2 cents but JDOM is inherently slower than other XML
processors and on a mobile platform that's usually not what you want,
you should use SAX or something that's built into the API (if
possible).

I know using SAX and some other methods are a bit more work however if
you're parsing on a mobile platform your users will appreciate it.

[android-developers] Re: SQLiteOpenHelper per activity??

[gcstang]

I still see this error when using a ListView even though I have it set
to close and clean up the connection when leaving the view, can't do
it right away or the ListView won't work.

Any way around this?

[android-developers] How to make Rating Bar small and if I click it open a Dialog to change

[gcstang]

I've tried using

style="?android:attr/ratingBarStyleIndicator"

but that makes it non interactive, can I wrap it or something to make
it so you can click the bar and it opens a Dialog with a full Rating
Bar that can be changed?

The large one is just huge for the display I'm trying to achieve.

Thank you,

[android-developers] Newer Market Comments Disappearing?

[gcstang]

I've noticed over some time that some comments are disappearing and
not just old ones but ones that have recently been placed, is this a
bug?

The comment that I noticed was placed on 6/3 but doesn't show on the
phone, it only shows on some sites that index the market.

[android-developers] Re: SQLiteCursor on that has not been deactivated or closed

[gcstang]

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.

[android-developers] SQLiteCursor on that has not been deactivated or closed

[gcstang]

I've followed the try/finally approach but still get this error.

Is there anything else that can be done?

Here is what I have.

MediaDbAdapter mDbHelper = null;
Cursor c = null;
try {
mDbHelper = new MediaDbAdapter(ctxt);
mDbHelper.open();
c = mDbHelper.findByX(data.getX());
if(c != null) {
   //Do an Update on the database
}
else if(c == null) {
  //Do an Insert on the database
}
} finally {
if(c != null) {
c.deactivate();
c.close();
c = null;
}
if(mDbHelper != null && mDbHelper.isOpen()) {
mDbHelper.close();
}
}

[android-developers] Re: Google should prohibit task killers on Android Market

[gcstang]

Way too extreme, without the Task Killers battery life on most phones
would be horrible and the speed even on some phones such as the Droid
would slow down too much waiting for background tasks to die on their
own.

Although I understand your frustration there has to be a better
resolution for now awareness is about your only avenue.

[android-developers] Re: Android: Trusting all Certificates using HttpClient over HTTPS

[gcstang]

This works for me information found on multiple sites but mostly from
anddev.org :

1. Create a Fake Trust Manager
public class _FakeX509TrustManager implements X509TrustManager {

private static TrustManager[] trustManagers;
private static final X509Certificate[] _AcceptedIssuers = new
X509Certificate[] {};

@Override
public void checkClientTrusted(X509Certificate[] chain, String
authType) throws CertificateException {
}

@Override
public void checkServerTrusted(X509Certificate[] chain, String
authType) throws CertificateException {
}

public boolean isClientTrusted(X509Certificate[] chain) {
return true;
}

public boolean isServerTrusted(X509Certificate[] chain) {
return true;
}

@Override
public X509Certificate[] getAcceptedIssuers() {
return _AcceptedIssuers;
}

public static void allowAllSSL() {
HttpsURLConnection.setDefaultHostnameVerifier(new 
HostnameVerifier()
{
@Override
public boolean verify(String hostname, SSLSession 
session) {
return true;
}

});

SSLContext context = null;
if (trustManagers == null) {
trustManagers = new TrustManager[] { new 
_FakeX509TrustManager() };
}

try {
context = SSLContext.getInstance("TLS");
context.init(null, trustManagers, new SecureRandom());
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (KeyManagementException e) {
e.printStackTrace();
}


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();

[android-developers] Re: Progress Bar in every row of ListView

[gcstang]

Do you have example code that you used to get the images to work?
I've tried this and my listview gets really slow after scrolling
through once then trying to go back through it.

Thank you,

[android-developers] Re: Color Picker Preference

[gcstang]

How did you use it?  I'm faced with the same issue but not sure how to
open it and save to a preference key.

Did you use another preference to open it or something?
