You'd also probably need to keep your version numbers aligned between the free unlocker apps, because it has been established that this will cause an LVL failure. IF this works, it would be much cleaner; it would mean that your users would never have to actually have the unlocker installed, just purchased. I can't see that this sort of thing is mentioned anywhere in the LVL docs (though of course I could be missing it).

[android-developers] Re: If I turn off Copy Protection, what will happen?
I have just gone through exactly this, except my app is free. 1. I know a (pathetic) 6 people with Android phones. One couldn't see my app. We compared which apps he could see; he was missing about 10% including mine. 2. The user who couldn't see the app owns a Samsung Galaxy. There is a known issue that it will not accept copy protected free apps. 3. I removed copy protection from my app and updated the Release number. Everything worked exactly the same in the market, no problems. 4. My friend could still not see the app. But by the next day, downloads had increased ten fold. I did make a couple of other minor changes, and at that stage it had only been on the market for a week. I can't see how this is related to removing the copy protection, because both before and after I removed the copy protection 5 out the 6 users I know could download, most unlikely that suddenly 10 times as many people could download when it made no difference to thje 6 people I know. Neverthelessthe sudden jump did occur at exactly the same time, and has remained at that level. Whatever it was, I'm not complaining. 5. My friend still can't see it on his @#$%^ Samsung Galaxy.

Re: [android-developers] Reducing Permissions
On Mon, Aug 30, 2010 at 1:37 PM, Brad Gies rbg...@gmail.com wrote: I've been following the Is there a way to request permissions from a user as you need them? thread with a lot of interest, but even if someone is convinced to make the Android permissions system better, it doesn't do anything for right now. So, I thought I'd start a thread for coming up with alternative ways to reduce the permissions your app needs. My app absolutely needs internet access (it's useless without it), and it uses Google Maps extensively (it's the main activity), so I have the following : uses-permission android:name=android.permission.ACCESS_NETWORK_STATE/uses-permission uses-permission android:name=android.permission.ACCESS_COARSE_LOCATION/uses-permission uses-permission android:name=android.permission.ACCESS_FINE_LOCATION/uses-permission uses-permission android:name=android.permission.INTERNET/uses-permission I want to be able to know if I have a network connection, hence the ACCESS_NETWORK_STATE. I also try to use GPS hence the ACCESS_FINE_LOCATION, and if GPS is not available I try to find the user's location using something else hence ACCESS_COARSE_LOCATION and of couse the INTERNET permission. I also use the My Location' feature of Google Maps. So... the question is : Is there a robust way to use Google Maps, and be able to send requests to my server without all those permissions (in a user friendly way) ? If you use maps with locations extensively, then internet and location permissions are *fundamental* to your app and I would argue that it would be entirely wrong for these to not be presented to the user when it is installed. Why are you thinking these should not be presented? From what you say, it sounds like this is what your app does. It doesn't seem to me that you should need a permission just to find out if there is a network connection. To be honestly, I am not that familiar with the networking parts of the system, so I don't know for sure how to address this... though from glancing at the API, it seems like the ConnectivityManager.CONNECTIVITY_ACTION broadcast is a sticky broadcast so you can retrieve the last broadcast state without any permission? Also this permission is a normal permission, not dangerous, so it won't be shown to the user unless they explicitly want to see it. I'm also experimenting with C2DM, so I have the following: permission android:name=com.bgies.hottonight.permission.C2D_MESSAGE android:protectionLevel=signature / uses-permission android:name=com.bgies.hottonight.permission.C2D_MESSAGE / uses-permission android:name=com.google.android.c2dm.permission.RECEIVE / uses-permission android:name=android.permission.READ_SYNC_SETTINGS/uses-permission If I want to use C2DM, it seems I am stuck with those... Anybody know signature-only permissions are never shown to the user, so they are not of concern here. (And also since you are declaring the permission, if it was shown to the user, you could have it say whatever you wanted... such as makes app work better than competitor X. Though actually, since the platform doesn't know about the perm until the app is installed, it just won't be displayed anyway.) The C2DM receiver permission... makes me unhappy. First because the permission text that gets displayed is utterly ridiculous. Second because I really question the value of this permission at all. At the very least, for the next release I hope to make this a normal permission so it isn't shown to the user unless they explicitly display it. I also really want to reword the text to make it less crazy. And as far as READ_SYNC_SETTINGS... why do you need that? I don't see it mentioned anywhere in the C2DM documentation. (Though this also is not an area I am super knowledgeable about.) Now... I also want to use the camera (optional) and vibrate (optional but most users will want it) so I have to add : uses-permission android:name=android.permission.CAMERA / uses-permission android:name=android.permission.VIBRATE / Here again, vibrate is a normal permission, so it will not be seen unless the user wants to dig into it. (And seriously, makes your phone vibrate. I think the vast majority of users, if they *do* explicitly go to see it, will have no trouble figuring out that they are okay with it.) As for the camera permission, the only option I can offer is if you just need them to take a picture then you can start the intent to have the camera app take a picture and return it to you. However if you need to drive the camera yourself, you'll need to take the permission. Total 10 lines of permissions in the manifest AND this is AFTER removing 4 other permissions that a small percentage of users would have found very handy, AND not adding a few other features because of the permissions bloat they would have added CALL_PHONE READ_CONTACTS GET_ACCOUNTS SEND_SMS So... given all of this, is there a way to reduce

Conclusion: I'm an idiot (shocked!?) So, for those of you that care, here was the problem.

This cache is wiped on each update to refresh the data and avoid issues exactly like this. At least it's *supposed* to be wiped. Unfortunately, while developing the latest version, I apparently inadvertently removed the single line of code that clears the cache when the app is updated! Genius! So the new code was trying to load the old cache which was missing a new piece of data (which it otherwise would get from that static map discussed earlier). I had no idea I'd removed that line to clear the cache so I didn't even think it to be a possibility! I assumed all users were getting fresh data.

[android-developers] Re: layout_gravity
I believe that layout_gravity (for LinearLayout) probably only has an effect if it specifies a direction that is orthogonal to the orientation of the layout. Ie if the LinearLayout orientation is horizontal then the only acceptable layout_gravity options fors its children are top, bottom etc (and NOT left, right, center_horizontal). Happy now. Thanks everyone. That's very possible. Good to remember that one, if though it's a bug IMO, or at least, it should put a warning into the log that the attribute is being ignored. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: Can Android 2.X connect to 3G and Wifi data networks simultaneously?
Indeed but imagine a case where you have two options (after spending quite a lot of resources on a project already): a) Don't release your software at all. b) Release your app and use hidden constants( that do work on current devices) but risk with the fact that your application will break in the future and you have to fix it again. Which one would you choose? Btw, the operator requirement that apps can only use 2g/3g networks and not WiFi, comes up quite often when your application has anything to do with some carriers around the world. The sad part is that sometimes this comes as a surprise to app developers because the operator mentality is We didn't tell you about this in the beginning because we thought that it's a trivial change in your app anyway - the same app can do this on platform X so it has to be able to do this also on Android! And as far operators are concerned, NO is not an answer :) On 1.09.2010 13:44, Mark Murphy wrote: My point is that it is not in the Android SDK and therefore is not safe to use.

Which one would you choose? The right answer is: c) Do your homework first and don't write apps that can't be implemented -- the carrier limitation you describe is a well-known problem Of the two choices you outline, if your end distribution channel is a pre-load on a device through a specific carrier, go with b). Or, if this app is being done on a consulting basis, and the customer gives the go-ahead, go with b). Otherwise, go with a), because the future costs (in terms of time, reputation, etc.) have a good chance of exceeding your revenues. I am all for lobbying to have this promoted to be in the SDK, because it's a seriously useful feature, for a variety of reasons (though I could see requiring a permission for it). If there's no issue in b.android.com about putting this in the SDK, you may wish to add one. However, the business decision for going forward with distribution has to be made on future costs and revenues -- it does not matter one bit how much time you have put in to date. If the costs are controllable (i.e., distribution is limited to certain devices), or if the costs are incurred by somebody else (i.e., consulting client), and the revenues are known, it may make sense to run the risk. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Android Development Wiki: http://wiki.andmob.org -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] ListActivity with Button at bottom
Use a RelativeLayout, putting the Button at the bottom and anchoring the ListView to the top of the screen and the top of the Button. Or, use a LinearLayout, setting the ListView's android:layout_height to 0px and its android:layout_weight to 1, and leaving android:layout_weight off the Button.

[android-developers] Re: softKeyboard's next button not taking focus to the next edit text
Figured it out. I thought android will automatically create id's for
dynamically created UI elements. Thats why I put
*
input1.setNextFocusDownId(input2.getId());
Here I was not assigning any id explicitly for input2.
If I set explicitly some id to input2 and the set the next focus down id,
it worked.

[android-developers] Memory problem with UI elements
Hi, In my application I change layouts very frequently with most of the user interactions. Each time when a new layout is drawn, the applications memory size is increasing. I can see this in DDMS. This is absolutely fine. I have analyzed my application with memory analyze tool and it shows that there around 42 Table layouts at some point of time and this number increase as user does more interactions with the app. Now my question is why doesn't the GC collect the stale layout objects. Does GC collect on UI widgets also??? I feel it does but can any one tell me what may be the reason for GC not collecting my UI elements.

ok I know I can always press on phone back button, but I want to mimic such a functionality and allow a user can choose option from option menu. the problem I see is that when starting activity by passing context and next-activity-name I cannot get context (the caller) from intent that started that (next) activity. on the other hand I could pass a name of the caller to intent and retrieve it on callee side, right. so the last question If I got this right when I call startActivity() another activity is brought to front and caller is paused marked by GC but not distroyed. but I could call finish() method on a caller and destroy caller once for all, is that right? -- You received this message because you are subscribed to the Google Groups Android Developers group.

Hi there...
I'm having an issue with a Bitmap which is giving me an error but any
kind of report so I can understand it..
The code is simpley this this:
- I get a image path from a bundle:
Bundle w = getIntent().getExtras();
final String thenPicPath= w.getString(oldpicpath);
- And I set it on a ImageView called returnpic:
Bitmap oldPicture = BitmapFactory.decodeFile(thenPicPath);
returnpic.setImageBitmap(oldPicture);
In the debugger the String thenPicPath reads : /sdcard/download/

And the oldPicture Bitmap reads: android.graphics.bit...@437700c0
Everything looks fine but I get and error when setting the
imagebitmap.. any clue?

[android-developers] Re: traversing activity stack
just one more thing, what is the difference between startActivity and startActivityForResult, can I have two activities of the same class on a stack displaying ie list with different data each? in another words what android really does when startActivity is called, does it resume or create activity and reload all data view needed so I can have only one activity of a given class or is it always creating new instance of the activity no matter there is one already created. from my point of view when startActivityForResult is used android for sure must preserve caller's state as app will eventually return to caller with result.

[android-developers] Edittext Cursor and Highlight Problem
I am trying to implement a textview which has select text/copy and paste functionality. I tried to do this by making an Edittext with the following properties. I currently have the following Edittext: EditText style=?android:attr/textViewStyle android:editable=false android:background=@null android:textColor=@null android:id=@+id/textbox/ I want users to be able to highlight the text with long click -- select text. This works fine with the above code and the highlights of selected text come out fine. However I do not want the cursor to always be flashing. I successfully get rid of the cursor by using: textBox.setCursorVisible(false); However with this change whenever a user long clicks and hits select text, the highlighted text no longer has any color over it. I have tried to change the color of the highligthed text to textBox.setHighlightColor(android.graphics.Color.RED); But this does not seem to have any effect.

[android-developers] GOOGLE, WHAT IS GOING ON with the Active Install %? Bug in install to SDCARD is my guess!
Yes we have threads about this already but we still have not gotten an answer AND I think it's about time somebody at least explain what does this number actually MEAN. I'm getting frustrated with the lack of transparency on this. My apps used to be around 56% active installs VERY soon after I updated the apps to allow install to SDCARD (preferExternal), then the active install count started dropping like a rock. Now it's around 39% today for my main app. My opinion is there is a bug in the SDCARD install feature somewhere that is not counting those installs. We know there already is a bug with home screen icons if you install to sdcard you will get a blank icon until the Home app restarts. Actually probably time to submit this issue in the bugtracker. -niko20 -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: EditText field not update, how to do this?
You should update the value of you EditText in onResume(), which you don't seem to have right now. That is called when your activity returns to the foreground. At that point you should have your new value and you just do a setText() on the EditText to display the new value.

[android-developers] Understanding Horizontal Scrollview and relationship to bitmap
I am creating an app with a very long horizontal custom view (about 500 pages horizontally). I don't draw to it often enough to justify using a surface view. As I approached the problem I inserted my custom view into a horizontal scroll view and that works OK. Still, I think it can be smoother. Right now it redraws the whole bitmap each time. So I tried creating the bitmap by hand and discovered that it is too large - the VM won't allow the memory to be allocated. This is, of course, a big clue to how the HorizontalScrollView draws to the canvas. So, I'd rather redo the onDraw function to use a smaller bitmap. I don't quite understand, though, how the bitmap, canvas and horizontalScrollView are related and I need some strategy suggestions as to how to go about this. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: GOOGLE, WHAT IS GOING ON with the Active Install %? Bug in install to SDCARD is my guess!
As stated in the other thread, the problem may just be that the algorithm that computes active install percentage may just be more accurate now. It could also be that your user base started uninstalling your app when you posted the update. Many people will uninstall an app they haven't used for a while when an update comes around because they are reminded they have it. I too have seen a drop from 64% to 61% in one of my apps and from 58% to 47% in another. Is this a problem or a correction? I guess we may never know. Regardless, since it's happening to everyone, it won't affect your position in the market or anything else tangible, so you might as well just live with it. -John Coryat -- You received this message because you are subscribed to the Google Groups Android Developers group.

I don't draw to it often enough to justify using a surface view. That would seem to be bad from a memory consumption standpoint. For example, a ListView on an ListAdapter with 500 rows does not create 500 row Views, but rather only as many as can be shown on screen. That's a performance optimization, to minimize runtime memory usage. ScrollView/HorizontalScrollView do not do the same, forcing you to allocate 500 pages worth of content up front.

Another strategy, if you can settle for a page at a time metaphor, would be to use ViewFlipper. Set up horizontal swipe animations to move between pages. You then only need 3 pages at one time: -- Load in 3 pages and show the user the middle one -- On a flip, remove the outlier page (one that is two away from the current page) and add another page in the direction of the flip, if applicable I should be releasing a ViewSwiper component shortly that demonstrates how to use a GestureLibrary to swipes to flip between children of a ViewFlipper.

[android-developers] SQLite implementation - need help!
Hello All
I'm stuck on an SQLite problem and have been for the past few day so I
thought I would share it with you.
All I'm trying to do is create an SQLite database to display the data
generated by the use of my app.
I've managed to get the app to send data to a MySQL database (quite
easily) but for some reason I'm finding this really difficult.
I've made a DB helper class which creates the database and adds one
table to it. I would like to create two tables but achieving one table
for now would be great!
public class DBHelper extends SQLiteOpenHelper
{
// Database constants
private static final String DB_NAME=ScoreStore;
private static final int DB_VERSION = 1;
public static final String TABLE_EVENT = event;
public static final String COL_ENTRYID = entryID;
public static final String COL_EVENTNAME = eventName;
public static final String COL_DATE = date;
public static final String COL_EVENTTYPE = eventType;
public static final String COL_NUMROUNDS = numRounds;
public static final String COL_PLAYSPERROUND = shotsPerRound;
public static final String COL_PLAYER = player;
public static final String COL_DISTANCE = distance;
public static final String COL_TOTALSCORE = totalScore;
public DBHelper(Context context)
{
super(context, DB_NAME, null, DB_VERSION);
// TODO Auto-generated constructor stub
}
/** Database created for the first time */
@Override
public void onCreate(SQLiteDatabase db)
{
String sql = create table+TABLE_EVENT+
(_id integer not null primary key autoincrement,+
COL_ENTRYID + integer, +
COL_EVENTNAME + varchar, +
COL_DATE + date, +
COL_EVENTTYPE + varchar, +
COL_NUMROUNDS + integer, +
COL_PLAYSPERROUND + integer, +
COL_PLAYER + varchar, +
COL_DISTANCE + varchar, +
COL_TOTALSCORE + integer, );
db.execSQL(sql);
}
/** Updates the database based on version id */
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int
newVersion)
{
}
}
Then when I want to add data to the DB I use this code...
DBHelper dbHelper = new DBHelper(this);
SQLiteDatabase db = dbHelper.getWritableDatabase();
//Load data
Cursor cursor = db.query(DBHelper.TABLE_EVENT, null, null,
null, null, null, null);
startManagingCursor(cursor);
// populate the database
ContentValues values = new ContentValues();
values.put(DBHelper.COL_EVENTNAME, Test name);
values.put(DBHelper.COL_DATE, Today);
values.put(DBHelper.COL_EVENTTYPE, Test type);
values.put(DBHelper.COL_NUMROUNDS, 1);
values.put(DBHelper.COL_PLAYSPERROUND, 4);
values.put(DBHelper.COL_PLAYER, Tester);
values.put(DBHelper.COL_DISTANCE, 100 yards);
values.put(DBHelper.COL_TOTALSCORE, 45);
db.insert(DBHelper.TABLE_EVENT, null, values);
// Set the list adapter
String[]from = {DBHelper.COL_ENTRYID,
DBHelper.COL_EVENTNAME,
DBHelper.COL_DATE, DBHelper.COL_EVENTTYPE,
DBHelper.COL_NUMROUNDS,
DBHelper.COL_PLAYSSPERROUND,
DBHelper.COL_PLAYERS,
DBHelper.COL_DISTANCE,
DBHelper.COL_TOTALSCORE};
int[]to = {R.id.the name of my textview};
// Put retrieved data into a list view
SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,
android.R.layout.simple_list_item_1, cursor, from, to);
setListAdapter(adapter);
registerForContextMenu(getListView());
The app runs fine until I try any of the above, then it just crashes.
2 1/2 Questions...
What am I doing wrong? Is what I'm doing hopelessly, completely
incorrect?
Once I've fixed this, how do I make it work for two tables?
Any help would be very much appreciated.

You were right. It appears that it's something wrong with my phones WiFi. The problem should be that it's not responding to the ARP request.

What is the preferred method to send a drawable (like a bitmap) to
another activity (such as the Gallery app) then?

Please don't send bitmaps like that. When you start an intent, the bitmap
needs to be marshaled for delivery (one copy). It is then delivered to the

be delivered back to the app as a another bundle (and another copy).

Im not sure how to pass a drawable..
so the issue was the bitmap i was trying to send w.putParcelable(
bitmap, selectedDeviceImage);
, now I have to find another way to send this lol
it actually has a value so I'm not getting why the error.. but anyway..
I'll try other ways to send a bitmap, or convert it to byte something like
that.

although I cant find a solution to send the bitmap. is there a way to
retrive a bitmap from an imageview?

I noticed that your code for the upload case doesn't close the dialog,
like the code for the picking case does. Perhaps you could try that.
Also, try getting the context using Java notation for the enclosing
activity class (blah.this), although I think it's the same as v.getContext.
What might be happening is your code crashing and Android restarting
next-to-last known activity.
You could also use an activity in place of a dialog, using
startActivityForResult.

Re: [android-developers] Reducing Permissions
Actually, you are correct. Many of the permissions don't show to the user. It's been awhile since I installed the app from the internet, but I do have it installed as a draft in the market, so I was using the market stats (silly me... ). This apk requests 13 permissions that users will be warned about android.permission.ACCESS_COARSE_LOCATION android.permission.ACCESS_FINE_LOCATION android.permission.INTERNET android.permission.CAMERA android.permission.READ_CONTACTS android.permission.VIBRATE android.permission.CALL_PHONE android.permission.VIBRATE android.permission.ACCESS_NETWORK_STATE com.bgies.hottonight.permission.C2D_MESSAGE com.google.android.c2dm.permission.RECEIVE android.permission.READ_SYNC_SETTINGS android.permission.GET_ACCOUNTS So... obviously, we should be asking the market to be updated to show what the user will actually be asked for... (I know... but I can dream). The permissions shown to the user are (the version I have compiled with a production key didn't have the C2DM stuff in it, so I'll have to recompile it and see what C2DM does show to the user). Network Communications Your Location Phone Calls (won't show anymore because I've removed it in the latest version) Services that cost you money (also shouldn't show anymore because I call the SMS with an intent now) Storage (I'm going to see if I can get rid of that today) Your personal information (that should also be dropped with the latest version, but it does remove a very handy feature) Hardware Controls That is not as bad as I was thinking because I will be able to get rid of 3 of those, but at the expense of either removing features, or making them less seamless. For instance, both the phone calls and SMS will now use an intent which means that it's an extra screen and button click for the user, which for me makes it look clunky (hopefully the average user won't notice too much). I still want an ask the user optional permission for the read contacts because even though my app will drop using them for now, it would be a very handy feature for them. Just so you know, my app is about connecting with friends, and being able to access their friends email addresses one time would save the users a lot of typing and setup later. But, it's just not worth it to have to declare it in my app as if I will be ALWAYS accessing them, and THAT does remove a very handy feature, that I would keep if I could just ask the user the one or two times they would actually use it. It's actually a HUGE issue for me because not keeping it means that many users may not find my app all that useful because they won't get it setup to find their friends easily, while keeping it means that many users will never install it. Damned if I do... Damned if I don't... and right now there is no good answer.

Hello All
I'm stuck on an SQLite problem and have been for the past few day so I
thought I would share it with you.
All I'm trying to do is create an SQLite database to display the data
generated by the use of my app.
I've managed to get the app to send data to a MySQL database (quite
easily) but for some reason I'm finding this really difficult.
I've made a DB helper class which creates the database and adds one
table to it. I would like to create two tables but achieving one table
for now would be great!
public class DBHelper extends SQLiteOpenHelper
{
// Database constants
private static final String DB_NAME=ScoreStore;
private static final int DB_VERSION = 1;
public static final String TABLE_EVENT = event;
public static final String COL_ENTRYID = entryID;
public static final String COL_EVENTNAME = eventName;
public static final String COL_DATE = date;
public static final String COL_EVENTTYPE = eventType;
public static final String COL_NUMROUNDS = numRounds;
public static final String COL_PLAYSPERROUND = shotsPerRound;
public static final String COL_PLAYER = player;
public static final String COL_DISTANCE = distance;
public static final String COL_TOTALSCORE = totalScore;
public DBHelper(Context context)
{
super(context, DB_NAME, null, DB_VERSION);
// TODO Auto-generated constructor stub
}
/** Database created for the first time */
@Override
public void onCreate(SQLiteDatabase db)
{
String sql = create table+TABLE_EVENT+
(_id integer not null primary key autoincrement,+
COL_ENTRYID + integer, +
COL_EVENTNAME + varchar, +
COL_DATE + date, +
COL_EVENTTYPE + varchar, +
COL_NUMROUNDS + integer, +
COL_PLAYSPERROUND + integer, +
COL_PLAYER + varchar, +
COL_DISTANCE + varchar, +
COL_TOTALSCORE + integer, );
db.execSQL(sql);
}
/** Updates the database based on version id */
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int
newVersion)
{
}
}
Then when I want to add data to the DB I use this code...
DBHelper dbHelper = new DBHelper(this);
SQLiteDatabase db = dbHelper.getWritableDatabase();
//Load data
Cursor cursor = db.query(DBHelper.TABLE_EVENT, null, null,
null, null, null, null);
startManagingCursor(cursor);
// populate the database
ContentValues values = new ContentValues();
values.put(DBHelper.COL_EVENTNAME, Test name);
values.put(DBHelper.COL_DATE, Today);
values.put(DBHelper.COL_EVENTTYPE, Test type);
values.put(DBHelper.COL_NUMROUNDS, 1);
values.put(DBHelper.COL_PLAYSPERROUND, 4);
values.put(DBHelper.COL_PLAYER, Tester);
values.put(DBHelper.COL_DISTANCE, 100 yards);
values.put(DBHelper.COL_TOTALSCORE, 45);
db.insert(DBHelper.TABLE_EVENT, null, values);
// Set the list adapter
String[]from = {DBHelper.COL_ENTRYID,
DBHelper.COL_EVENTNAME,
DBHelper.COL_DATE, DBHelper.COL_EVENTTYPE,
DBHelper.COL_NUMROUNDS,
DBHelper.COL_PLAYSSPERROUND,
DBHelper.COL_PLAYERS,
DBHelper.COL_DISTANCE,
DBHelper.COL_TOTALSCORE};
int[]to = {R.id.the name of my textview};
// Put retrieved data into a list view
SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,
android.R.layout.simple_list_item_1, cursor, from, to);
setListAdapter(adapter);
registerForContextMenu(getListView());
The app runs fine until I try any of the above, then it just crashes.
2 1/2 Questions...
What am I doing wrong? Is what I'm doing hopelessly, completely
incorrect?
Once I've fixed this, how do I make it work for two tables?
Any help would be very much appreciated.

Yes, but it depends on your launch flags and the intents used to start the activities. in another words what android really does when startActivity is called, does it resume or create activity and reload all data view needed so I can have only one activity of a given class or is it always creating new instance of the activity no matter there is one already created. Again, depends on your launch flags and intents used to start the activities. from my point of view when startActivityForResult is used android for sure must preserve caller's state as app will eventually return to caller with result. Not necessarily. Preserving state is up to you. Android can and will kill the parent activity if it needs to. When the child activity finishes and it has to return to the calling activity, it will be restarted first and then have it's onActivityResult() method called. It's up to you to ensure it's ready for the data it gets back. - TreKing http://sites.google.com/site/rezmobileapps/treking - Chicago transit tracking app for Android-powered devices -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] SQLite implementation - need help!
The from and to arrays need to have equal size, and contain values
(column names and view ids) that are used for mapping data to UI elements.
Your code seems to try and map a number of data column items into one
text view.
The fix is to add more elements to the item layout, and specify themin
the to array, so each column in the from array is mapped to a view.
To display two (or more) tables, you use something called a table
join. It's a standard SQL construct, Google for it.
Finally, use logcat (in Eclipse or adb logcat on the host computer) to
see more detailed information whenever your application crashes.
Including the Java stack trace from logcat output with your questions is
also useful, as it helps others understand what goes on in your application.

[android-developers] DatePicker : size, font, etc...
Hi there ! Is there any way to change a datePicker size (I mean scaling it), or at least just the font's size ? The fact is that the datePicker frame displayed in the UI designer in Eclipse, is not the same than the one showing in the emulator : button parts are same but fields are bigger, wich is very annoying to setup proper fitting user interface in tight layouts. I didn't manage to apply a custom style either thanks a lot ! :) Cyril -- You received this message because you are subscribed to the Google Groups Android Developers group.

In other words, it is your anecdotes against his. I thought I would not need to remind you, but I guess I do: THE PLURAL OF 'ANECDOTES' IS NOT DATA! BTW: adducing the MIDP and Win7 experience is most unconvincing even for its already unconvincing anecdotal class. This is because in both those schemes, there was no alternative: you HAD to request permissions every time, even if it had been granted before. But Android already supports asking on a per application basis. Now it is time for my anecdote against yours AND his;) I got very fed up with both Win7 and MIDP under Symbian because it kept asking over and over, but I recognized that a major complicating frustration factor was that the Symbian implementation of the Socket and HTTP APIs was so busted in the first place. That is, it would have been far less annoying, IMHO, if the network connection had actually WORKED when I gave it permission to go ahead. But instead, it was asking even more frequently than their questionable design called for, because they had to keep setting up the connection again every time it broke -- which was SO often. So after suffering though that, what I decided was needed, what I THOUGHT this thread was going to drift to, was a two-tiered permissions scheme: allow granting some permissions on a per- application basis, but some on a per-run basis. That is not to say I am sure which should go to which. Perhaps the Manifest needs to grant the application permission to ask permission;) But thinking about this reminds me of another relevant data point: until the user sees an application ask over and over for net permission (for example), the user has only a fuzzy notion in his mind of when which application DO use the net (and when). This is one Achilles' Heel (that millipede may have many more) of the current permissions scheme in Android. Why, for example, does Bump need Network at all, if it is using Bluetooth to communicate between Bumper and Bumped? This is an example of why I have to agree with what was said earlier: the current permission scheme really does look like it was designed by software developers, NOT by a UX expert. But such features really do need to be designed as a joint effort between UX and security experts. Otherwise the difficult trade-off between usability and security will come out badly -- as it already has so often. While I am making proposals, I suppose I should also propose an enhancement of the current Internet permissions: separate permissions for low and high bandwidth. I propose this because when Android was designed, carriers were offering unlimited bandwidth plans for smartphones. But now they are backing away, offering unlimited data plans only for feature phones -- if at all. So now we can no longer splurge on bandwidth. Yet I have noticed that many websites and many web clients still assume we can splurge, forcing the poor user to load and reload what should have been cached as well as download lots of junk before he gets to the data he -really- wants etc. But on ATT, this can easily cause him to go over the 2G download limit on the high-end smartphone data plan. I know, because it has happened to me already;) Splitting Internet permissions into low and high does not solve the problem, but it might help mitigate it.

Obviously, the whole permission feature was designed by a developer and, IMO, it's not a very good system in a usuability sense. Oh my, I so very disagree with this. The current design is *very* much designed for end users. In particular, it is designed for *most* users. Not geeks, like you and me and the others on this thread. In the vast majority of cases when people are unhappy with the way things work, the requests being made are coming from geeks for them to do more geeky things. This thread is no exception. And this is very much an anti-goal. As an end user, I only care one and ONLY one permission: INTERNET. I only look for that one permission and the rest is just noise and might as well not even be shown. Why? Because I know as long as the app has no way of getting my personal info off my phone, I am good, as far as I am concerned, the app can read all my passwords and credit card info it wants, if it cannot do much with it anyhow. Sorry but you are wrong. When my wife got her Droid and started installing apps, she quickly came to me asking about a
[android-developers] stretch_copybit::run_render fail causing noticeable pauses in my display
Hi, I'm developing an Android game and I've got the garbage collection to the point where it GC's only about once every 5 minutes or so, which I think is acceptable, for now. The problem is that, every once in a while, I'll see this message in the logs: 08-29 09:58:46.410 W/copybit ( 1912): stretch_copybit::run_render fail 08-29 09:59:09.000 E/libs3c2drender( 1912): int S3c2DRender::DoG2D(unsigned int, s3c_img*, s3c_rect*, unsigned int, s3c_img*, s3c_rect*, int, int)::S3C_G2D_ROTATOR_18176 fail And when this message comes up, my game seems to pause for about 100-200 milliseconds.. I'm currently using a Canvas to draw with, although if my memory is accurate, I've seen this same error message using Open GL as well. Here's my code to draw the image object: cachedMatrix.reset(); cachedMatrix.postTranslate(-halfImageWidth, -halfImageHeight); cachedMatrix.postScale(localScaleX, localScaleY); cachedMatrix.postTranslate(localOffset.x, localOffset.y); float degrees = (radiansToDegrees(-rotation) + 360f) % 360f; cachedMatrix.postRotate(degrees); cachedMatrix.postTranslate(screenPos.x, screenPos.y); canvas.drawBitmap(image, cachedMatrix, null); Frankly, I am at a loss as to how to get around this. Has anyone else encountered this issue ? And found a workaround or insights into why this is happening ?

[android-developers] Bes resource to get started with Android development.
Hi, I'm looking for something to get up and running quickly with Android development. Perhaps a great tutorial covering the basics. I see a lot of posts on getting started but the ones I have looked over so far aren't great. What do people here recommend?
