[android-developers] Database error
Hi all,
I am creating a database to store the list of earthquakes as an update to my
existing app.
I am receiving an error with the following caused by statement:
Caused by: android.database.sqlite.SQLiteException: near ,: syntax error:
create table earthquakes (_id integer primary key autoincrement, date
INTEGER, details TEXT, latitude FLOAT, longitude FLOAT, magnitude FLOAT),
link TEXT);
My SQL statement is:
private static class earthquakeDatabaseHelper extends SQLiteOpenHelper {
private static final String DATABASE_CREATE =
create table + EARTHQUAKE_TABLE + (
+ KEY_ID + integer primary key autoincrement,
+ KEY_DATE + INTEGER,
+ KEY_DETAILS + TEXT,
+ KEY_LOCATION_LAT + FLOAT,
+ KEY_LOCATION_LNG + FLOAT,
+ KEY_MAGNITUDE + FLOAT),
+ KEY_LINK + TEXT);;
As far as I can see the statement is fine. Please help.
Thanks

UPDATE: I fixed it. I had a typo in the create statement. I accidentally
added a bracket after on of the floats.

[android-developers] Update widget(s) after application changes
Hi, I have an application that includes a couple of widgets. During development, I place the widgets on the homescreen of the emulator and start developing. When I'm working in Eclipse, and I'm pushing a new version of my app to the emulator, I sometimes have the impression that the widgets are becoming stale. Breakpoints that were on the widgets code don't appear to be active anymore (don't have the v marker), and the debugger doesn't suspend on them. When I remove the widget and I place it on the homescreen again, the breakpoint becomes active and the debugger starts suspending again. Is that something you need to take into account when developing widgets ? Also, when I push a new version of my app on the market, and my users already had the widgets on the homescreen, are they advised to refresh them by removing / adding them again ?

[android-developers] Re: How can Button clicks be sent to a View that has been disabled?
What is do some stuff doing? When you make changes to the UI, they
don't commit until after the current batch of code fully completes on
the UI thread. In your case, do some stuff will execute prior to
the button being disabled. So if you're doing some lengthy stuff in
there, the user might have the chance to click the button again before
it gets disabled.

I'm finding that some of my users are occasionally getting a button
firing twice in rapid succession (less than 100 millis) even though
the first thing the handler does is to disable the button. ie
button.addOnClickListener(new OnClickListener() {
public void onClick(View view) {
button.setEnabled(false);
// do some stuff.
}
});
Is this expected behaviour?
Ie that the InputEvents (button clicks) stack and will be sent to a
View even though the View is disabled?

Re: [android-developers] Update widget(s) after application changes
There are two issues here. One is, what happens to widgets when the application package is updated (during development or via a Market update). The way it's supposed to work is that all widgets get a chance to update via onUpdate. In practice, I've seen onUpdate get called, but the widget not reflecting the update, and stopping to function (not responding to clicks, the UI getting reset, etc.) on one device from a major company, out of the three I have. So for updates - there no need to instruct the users to always recreate your widgets, but it can be necessary on some devices. Two is debugging. I haven't seen this - but I'd check the DDMS perspective to make sure that the process actually connects to the Eclipse debugger (there is a bright green bug icon next to the process). Other than that, widgets are broadcast receivers, and as such, give you a very short time window once you've hit a breakpoint. If you spend more than a few seconds on a breakpoint that is triggered by onReceive, the process will get killed by Android, and lose the debugger connection. -- Kostya 09.07.2011 11:19, Davy пишет: Hi, I have an application that includes a couple of widgets.

[android-developers] Re: Galaxy Tab and Market filtering
Yup. They made it for a pretty good reason though. They tried using mdpi drawables, but so many apps simply looked better with hdpi drawables. Unfortunately, many developers still think that mdpi means 320x480. And many developers ignore tablets because they are expensive and the emulator is too slow. That's off-topic though. The topic of this thread is to find out how the Device Availability dialog in the Developer Console (and Android Market in general) deals with the compatible-screens tag.

[android-developers] Re: EditText and the unwanted Quick Search Box
I believe that I've come up with a work-around - at least in my case.
I don't know why this works, but the problem hasn't reappeared in the last
month after making these changes.
The app has TTS and Voice Recognition. I was doing all the setup by creating
an asynctask from the onCreate of the main activity. In an act of pure
desperation, I moved the instantiation of the asynctask into a runnable that
I executed with delay of approx 100ms.
I have no idea why this worked, but apparently the create was able to finish
and whatever was confusing the EditText seems to have gone away. While I'm
not confident that this will work in all cases (or if I just got lucky), if
you are still having difficulty, try moving whatever system
altering/registering tasks otherwise done in the onCreate and see if that
helps.
While the following code snippets aren't going to be particularly relevant
to your app, I'm including them for the sake of example.
* At the end of onCreate*
// Feeble Attempt to fix google qsb issue
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
new InitialLoads().execute();
}
}, 100);
* The AsyncTask that gets called *
private class InitialLoads extends AsyncTaskVoid, Void, Void {
@@Override
protected Void doInBackground(Void... arg0) {
PackageManager pm = getPackageManager();
/* establish whether the TextToSpeech class is available to us */
// static {
try {
WrapTTS.checkAvailable();
mTTSClassAvailable = true;
}
catch (Throwable t) {
mTTSClassAvailable = false;
}
// }
if (mTTSClassAvailable) {
Intent checkIntent = new Intent();
checkIntent
.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
// Check intent to make sure TTS can be satisfied. Then start
// the activity if it is OK to proceed.
ResolveInfo resolveInfo = pm.resolveActivity(checkIntent,
PackageManager.MATCH_DEFAULT_ONLY);
if (resolveInfo == null) {
// Not able to find the activity which should be started for
// this intent
}
else {
startActivityForResult(checkIntent, REQUEST_TTSOK);
}
}
// Check to see if a recognition activity is present
ListResolveInfo activities = pm.queryIntentActivities(new Intent(
RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);
mVoiceAvailable = activities.size() 0;
if (!Constants.IsProduction) {
// Force voice available on the emulators
mVoiceAvailable = true;
}
// For use with preference screen
AdvPreferences.INSTANCE.setVoiceAvailable(mVoiceAvailable);
return null;
}
}
Best of Luck.

[android-developers] My Anti Cracking Function
Hello everyone, I am placing next my anti-cracking\anti-reverse-
engineering function.
The idea of sharing this function is to allow other developers to get
its benefits, and also to get more ideas for improvement, and even
though exposing it to hackers makes it weaker, the idea is also that
the function should be tempered by developers before using it instead
of just copy/paste, and even split it into several functions to be
called across your application. At the end if a hacker wants to crack
your app, he will, but sure we can make it a bit harder.
For the CRC validation performed in the function follow the next
steps:
Export a signed package of your application the same as if you would
be getting ready to publish it. Rename the file extention .apk
to .zip, extract the classes.dex file.
Then use any internet CRC calculator tool with the extracted
classes.dex file, you can find many in google (i.e.:
http://www.createwindow.com/programming/crc32/crcfile.htm)
Copy the obtained CRC value, go back to your IDE and open any layout
xml file, place this value as the tag of any element (i.e.:
android:tag=d7abbe13).
Though you can really store the CRC value into other ways as an asset
file, etc. I encrypt this value before passing it and decrypt it at
runtime so is even harder for the hacker by not allowing him just to
copy his CRC value if he finds its location.
The idea is that before calling the function you should get back the
CRC value and pass it.
Is very important that you do not copy the CRC value into any of your
java code, if after the CRC calculation you temper on any way with
your code the CRC value will change and you will need to star this
process again.
Finally you only need to export the signed application again. The CRC
will still reamin the same for the classes.dex, but somewhere hidden
in your layouts you will have your CRC value to be validated by the
function.
As final note when developing the application do not call this
function or you will get crazy :)
So any comments and new ideas?

[android-developers] Invalidate only one map overlay
Hi, I'm doing my own MyLocationOverlay implementation to bypass extremely slow current position display. The problem that I've is that I want to make a little animation changing the color of the position marker and the only way I know to redraw is to call invalidate o MapView. But that way I also invalidate all the other overlays. Is there an efficient way if only I want to change color and other overlays don't need redraw?

Re: [android-developers] InApp Billing problems
Joan, I'm seeing two somewhat serious issues right now. First, if an order doesn't go through on the first try (either incorrect credit card data, or the mysterious Google error where they are unable to process the transaction in a timely fashion), then the application will never receive a purchase complete notification. Google has been in the process of rolling out a fix for this since June 26. I'm not seeing as many cases in my application now as back then, so perhaps it's fixed to some extent, but at this time it's still on the known issues page: http://www.google.com/support/androidmarket/developer/bin/static.py?page=known_issues.cs Strangely enough, refund notifications go through immediately within a few seconds. Second, besides the first issue, some 3-5% of order notifications get lost. Asking the user to reinstall the app, which triggers a restore transactions operation, works every time (except in the first case, above). Some smaller issues are: the unable to process the transaction in a timely fashion error, misleading emails sent to the user when something goes wrong (the seller canceled your order for the above error - expect to get emails asking why you did that). -- Kostya 09.07.2011 18:13, Joan Pujol ?: Hi, I plan to use InApp billing to provide a premium version with some extra features and without ads.

Re: [android-developers] Help. I need to pull and eventually send a value via webview
OK. Awesome I will give it a try this week and let you know. I appreciate
the help.

To download the data, you can use either standard Java URL and
URLConnection classes or the HttpClient from apache included in Android.
Googling those classes should result in some decent hits. You can then parse
the String to get the value and then pass the page to your WebView by
calling it's loadData or loadDataWithBaseURL methods.

No, no I did not think of that. Mainly because I do not know how to do
that. Is that done in a webview? Can you tell me what I am to google to
learn how to do this or perhaps point me to some code or tutorial?

OK so it does not need to be webview but that's the closest I have
gotten to solving my problem. (going on 2 weeks now).
ok so right now I am using a webview to go and see a page. On that
page is a hidden input tag with an id and value.
I need to pull that value and use it in java. Eventually I need to
send something also. I have this all working in a blackberry webworks
app using javascript and ajax.
I think I'm close but I cant seem to modify my code to get the right
result. with this code I can get all the html on the page but not
just the one thing I want. This is put into an alert.
How do I get just the value and then how do I get it so the java will
read it.

[android-developers] Re: My anti-cracking \ anti-reverse-engineering function
Good idea, but I can see immediately how anti-lvl can be adjusted to get around this with only a couple of lines of xml. I don't want to be dismissive of all the effort you've done here, but I've spent just as much time coming up with cunningly similar solutions only to see them broken by a single line of code added by a smali hack. So, to get around your issue, it simply requires you to stick this in the xml in anti-lvl: 1. Find a method in the app that accepts a Context, String, String as parameters 2. If this method includes a mention to getCrc() method of the class ZipEntry then continue. 3. Stick a return to the top of the method. I'm deliberately being vague here, but anyone who has looked in anti-lvl should be able to see that getting round your fix is *exactly* the sort of thing anti-lvl has been built for. However you can make this better by using the value of the crc for something in the app - e.g. compute the id for the main layout from the value of the crc and other fields added/subtracted/multiplied/etc. (NOTE: just an example, the id *may* change over time). If you can do something like that then if they hack the app to exit the method too soon, the app won't have the constructed the required value and later parts will fail. I strongly suggest splitting your method detailed above into several small pieces, chuck them about in many different abstract parts of the app. Call them in different orders and at random points through the app to construct a yes/no answer eventually. Don't make your app do this doing startup (as that's easy to spot), try spawning a background thread to do this after a random few seconds - don't make it to killProcess as that also sticks out to a hacker. Make it do something else like change important static values to something that is invalid and i.e. when they open the menu they get a nullpointer, etc, etc. All these things will help make it harder and give several more targets to aim for. Alternatively, a much more robust solution can be bought to you with the letters n, d, and k. :-) I really hope that helps you, good luck! -- You received this message because you are subscribed to the Google Groups Android Developers group.

You definitely need to know further details of the card (e.g. does it support NDEF?, does it support IsoDep?, what memory structures are used? what communication protocols are used? what chip does it contain? ...) As Dominik pointed out, a starting point is the tags tech-list. br, Michael -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: NFC card emulation, NXP PN544 and S2C (NFC-WI)
Hallo, the Nexus S device NXP PN544 NFC controller supports not only SWP for UICC based SE, but also the S2C (aka NFC-WI) Correct. for the external, e.g. micro SD card SE. Does anybody know how this can be enabled and what it means for the SD card? Well, as you mentioned yourself there is no SD card slot with the Nexus S. That is not relevant for the Google Nexus S (there is not SD card slot), but the NFC version of the Samsung Galaxy S II comes already with the SD card slot and here this will be a question. For the NFC version of the Galaxy S2 it won't change anything either (see below). I have tried to search for that and even the S2C standard seems to be relatively old (I think ECMA, 2006) I did not any related materials. What it means supporting S2C? The NXP544 has the built-in support, but what about the phone? Should the device have some hardware support like, e.g. antenna connectors in the slot and on the SD card to be connected directly to the RF interface? I think you misunderstood the concept of the NFC-WI here. A secure element that uses the NFC wired interface can support two modes: internal and external mode. In external mode, the SE uses the NFC chips (PN544) analog frontend + antenna for communication with RFID readers. In internal mode, the NFC chip accessed the SE as if it were an external contactless smartcard connected to the NFC chip. In either way the NFC-WI is used to transmit a digitized version of the signals that are normally transmitted over the contactless air interface. Thus, the SD card slot would not need some special features like antenna connectors, but it will need some special hardware support: To use SD card that support the NFC-WI, the SIGIN and SIGOUT signal lines of the NFC-WI would need to be connected to the NFC chip. But (yes, there's ofthen a but ;-) with the Nexus S (and I expect with the Galaxy S2 too) there is already a secure element connected to the NFC-WI. The Nexus S contains the PN65N (which is a combination of a PN544 and a SmartMX secure element chip). Those two chips are connected through the NFC-WI. br, Michael -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Highlight text incrementally
I have an application that will read what will be on a webpage and it will be highlighted. I have finished reading the webpage and putting it into a converter that then start saying it out loud. I want to know how to highlight the word when it starts talking and change which word is highlighted. Is this possible? I have tried getting the html code from the page, and then trying to add span bla bla /span but it doesn't change. I just have to find a way to move the span, Do you have any ideas? I want it to be in sync with the text that is being read. Thanks -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Update widget(s) after application changes
Thanks for the reply I'm also seeing on occasion that the widget is not reflecting the update, and stopped functioning. I even had at one point that the images on the widget were totally messed up (ex: drawables that are only shown on the main app activity all of a sudden appeared on the widget). Regarding the debugger, it was properly attached (green bug), but the (updated) broadcast receiver was somehow not properly loaded. (I made some changes in the broadcast receiver, and most likely due to a shift in line numbers, the linenumber where the breakpoint was located wasn't properly loaded, causing the debugger to never suspend on it). Other breakpoints (ex: on the main activity) kept on working fine. After I updated the widget (removing it and adding it again), the breakpoint got picked up, and the debugger would suspend on it. Never had real issues with updating apps (through market, or during local development in emulator) before I started working on the widgets. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Honeycomb and Gingerbread update introduced weird GPS behavior
Hi, I have a problem with an app using the LocationManager, to get location fixes via GPS on a user defined interval. I'm originally tested the app on 2 devices (Galaxy S running Eclair, and Asus Transformer tablet running Honeycomb 3.0.1). After I updated the Galaxy S) from Eclair to Gingerbread and the Asus Transformer tablet from Android 3.0 to Android 3.1, I noticed that my GPS was not working properly anymore. On both devices, it can now take several minutes (up to half an hour) to get a location fix. Before the upgrade, both devices were working fine before, and I never saw this behavior. The app that I'm testing uses the LocationManager to request location updates on a user-defined interval. I see the GPS icon blinking, but it doesn't get a fix. When I open other apps (Google Maps, Navigation, GPS Status.) it also takes a really long time to get a fix. Sometimes it does get regular fixes, but sometimes, it can take half an hour. Is it possible that my app can somehow be responsible for causing the GPS to get a lousy fix (and also impacting other apps) ? The only thing I noticed on the app is that in a particular corner case, multiple threads can requestLocationUpdates from the locationManager. This is currently marked as a bug (as it should do these calls sequentially, but I was just wondering if doing these calls multi-threaded can explain the bad GPS fixes, and if doing these calls can result in other apps having GPS issues as well.

[android-developers] Re: Closing AppWidget when force closing an application
Marcos, AFAIK, with that operation you're removing you appwidget from memory,that's the reason it doesn't work anymore. The only way to remove the widget from home screen is dragging it to the trashbin.

[android-developers] Lack of clicking in ListView
All,
I'm writing an app that has 3 tabs and a ListView as its first
screen. Here is a portion of the class that sets up the 3 tabs with
icons and then creates an intent for the MyList.class that is my
ListView class. This works. I can select the different tabs and it
switches between the three views. If I select the Tracking tab, I
get the ListView view.
Below the line of asterisks is a portion of code for the MyList
class. The issue is that I cannot select an item from the list. I
have seen examples where Listeners are used and examples where they
aren't used. This code DOESN'T have the listener. Is that why the
list is unresponsive? Or does it have something to do with the fact
that the ListView is part of the tabs scheme? I'ld love some
direction here
btw, R.layout.rowlayout in the code is the .xml defining the rows in
the listview. Nothing special, 2 lines of text and a thin progress
bar. As I said before, the ListView pains and scrolls fine. It just
doesn't select.
Thanks
Tony
