[android-developers] Re: Electro Magnetic Radiation Sensor with Android
Your problem statement is too vague to be useful. I don't mean so much useful to us, as useful to you. You really need to be a great deal more specific about what you want to sense. The term electromagnetic radiation covers a range from signals with wavelengths many orders of magnitude larger than your handheld, to ones with wavelengths many orders of magnitude smaller. And intensities vary from ones capable of vaporizing your handheld, to ones where you'd need a special isolation chamber and a good supply of liquid helium to be able to detect. And then finally -- with this be modulated, pure, mixed? Are you interested in determining the spectrum, the total energy flux, direction? Do you seek to resolve multiple signals? Hopefully, you'll just need one of the simpler combinations of the above factors, and can focus your efforts on that. Many smartphones come with a light detector, or a camera, which can be used for a certain range of electromagnetic radiation. If you're looking for powerline-frequency energy, or a similar range, consider a small tuned resonant coil, hooked to an A-D pin on an Arduino controller with a wifi or bluetooth interface. Microwave frequencies will require a whole other set of techniques and skills -- resonant chambers, etc. Infrared, UV -- the camera might work - try it and see. Narrow it down and your situation gets a whole lot simpler. On Jul 24, 11:14 am, Jaan jahnavi.athul...@gmail.com wrote: Hi , i am a student who is very new to Android platform.

Yes!!! Somebody with the same problem as me. Since I upgraded to SDK 2.2 Update 1, the resource file compilation is taking forever. Xavier suggested that I turn on Verbose in the Android build option, which I did. I can see the build process pause for a very long time when writing the .re_ file.

[android-developers] Re: Cam picture 'bigger' then preview
For anyone interested: The problem is there on a 1.5 G1, but not on a 2.1 Milestone/Droid. It might be the handset or the OS version, which i don't know. The basics of the problem as far as I can see, is that the preview is returned in 2:3 (320:480), and the picture will be in 3:4 (1536x2048). Using a scaling-factor I can at least predict _how_ the picture will change. On the milestone/droid the numbers for the preview are 480:640, which is also 3/4, so the scaling issue is non-existent. I tried setting the preview to something 3:4, but as the allowed preview sizes are limited, and I can't get them with the API lvl 5 memberfunction, I didn't get very far (and haven't tried that much). On Jul 18, 3:33 pm, EnnaN nhui...@gmail.com wrote: I could really use some help on this.

[android-developers] Need guidance in making the game's logic supporting multiple screens.
Hi. I've read the article Supporting Multiple Screen on Android developers site. But that doesn't apply to game logic. Let me get straight to the point. My situation is as follows: - I'm creating a game using LunarLander code as a base. - In my game, there'll be an object flying up from the bottom of the screen. The object will fly in projectile motion. - I set the starting velocity, gravity and angle so that the highest point(of projectile motion) is almost at the top of the screen. - The screen tested is Motorola Milestone. (480x854 resolution) Meaning the object travels around 854 pixels vertically. --- Problem --- When I test the game on small device (Android Dev Phone 1/G1) which is 320x480.(has only 480 pixels vertical) The object fly out of the screen because it is set to travel for 854 pixels. I'm thinking of adjusting starting velocity based on screensizes. But that sounds unreliable when we've so many devices/resolutions out there.

[android-developers] runQueryOnBackgroundThread on cursoradapter doesn't get called?
Hi All, I have a listactivity as a startup screen in my application. Which is displaying database records using custom cursor adapter. On create I set the filterable flag - getListView().setTextFilterEnabled(true) My cursoradapter overrides runQueryOnBackgroundThread which runs corresponding query. The problem is that after typing some text and hitting enter, runQueryOnBackgroundThread never gets called. However, when the item click in the same view launches another activity(detail view of the record) and I come back to the original list activity, hitting back button, then text filtering works just fine. I don't call setTextFilterEnabled anywhere except during the initialization process and I can't really find any other API affecting this behavior, so any guesses why text filtering doesn't work initially, but all of the sudden starts working when I come back to the list activity from child activity? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Application works after reboot the phone
hi Joseph,
i'm getting a security exception regarding the permissions regarding
the download manager or like that. any way the permission is not
listed in the manifest file. so after researching i found you need to
have android.permission.ACCOUNT_MANAGER in the manifest. don't know
whether thats the correct thing. but after that also i had the issue.
is this has something to do with application cache. even i tried to
clear application cache like this
public void clearCache() {
File dir = context.getCacheDir();
Log.d(CACHE,
Cached
CLEAREDDD);
if (dir != null dir.isDirectory()) {
deleteDir(dir);
}
}
public boolean deleteDir(File dir) {
if (dir != null dir.isDirectory()) {
String[] children = dir.list();
for (int i = 0; i children.length; i++) {
boolean success = deleteDir(new File(dir,
children[i]));
if (!success) {
Log
.d(CACHE,
Cached
CLEAREDDD);
return false;
}
}
}
// The directory is now empty so delete it
return dir.delete();
}
that also didn't work.
so what do you think,
regards,
Mike

[android-developers] Re: Weird sqlite behaviour. Can somebody explain?
If you store the phone number as a pure numeric, it will be stored and retrieved that way, no problem. If you store a number as 555-1212, I **think** SQLite will choke on the - in the middle while doing numeric conversion and store it as character data. If you store a number as -123245, SQLite will store that as a negative integer. But if you store a number as +12345, SQLite will store it as a positive integer and the + will be missing on retrieval. Whether you need to strip the quotes from the retrieved value depends, I suspect, on how you retrieve the value. If you retrieve the full query result string and parse that the quotes will be there, but I **think** there are ways to return individual column results in Java (getting my Java and C++ mixed up here, so a little foggy), such that the stripped value is returned as the appropriate String or int.

Obviously, if the bitmap is allocated outside of the Java heap then freeMemory() does you zero good. But my point was that freeMemory() only returns the amount of heap not allocated to objects at the moment. If there is heap allocated to dead objects (that would be collected by a GC) then that space is considered allocated, from the standpoint of freeMemory(). And, of course, there's no way to know how much dead heap storage there is without actually running GC. So whether or not the bitmap is allocated in Java heap, freeMemory() is not real useful, at least not without actually running a (full) GC cycle first. On Jul 24, 5:20 pm, Streets Of Boston flyingdutc...@gmail.com wrote: First a small correction on DanH's reply, ARGB_ uses 32 bits (4 bytes), not 64 bits. The memory used by a Bitmap is roughly Width*Height*Depth bytes. (e.g. a 1MPixel image in RGB_565 uses 2MByte of memory). I say roughly, because the Bitmap object itself, holding the raw data, occupies a few bytes itself. The problem is that the (garbage collector of) DalvikVM does not 'see' the raw image data. It only sees the the memory usage of the Bitmap object without the raw data (a few bytes). That's why the call to 'freeMemory()' does not seem correct. It only reports the difference between the max available memory minus the memory used by Java objects (which does not include raw image data). However, the raw image data does affect the memory usage of your app's Linux process, which is limited to either 16MByte or 24MByte. E.g. if your app's free memory is 1.5MByte and you create a 2MByte Bitmap, the DalvikVM does not see the need to run the garbage collector to free up old un-referenced objects, because to DalvikVM it looks like it only needs to create a few bytes for the Bitmap object itself and does not see the danger of a possible out-of-memory situation. In my image-editing app, i try to mitigate this (not quite solve it), by calling a System.gc() just before creating a (relatively) large Bitmap. This reduces the chance of an out-of-memory error.

[android-developers] Large jars in Android
Hi all, I looked for any info on this but could not find much. Originally I had a number of 3rd jars that I was importing into the Android project. The general concensus I got was that I needed to find the source for them and compile them in Android - well I kicked my behind and did all that and finally I have all jars in place for my Android app. The compilation and packaging of apk of the app with those jars sitting in the libs dir of the app takes 10-12 mins and towards the end it gives an Eclipse internal error and it quits! I tried doing this outside Eclipse using ant and still the same result. I have the java heap params jacked up for -xmx and -xms to 256MB and still no luck. The jars sum up to 6MB and the actual app to 0.25MB. The individual library directories that use to compile each of the 3rd jars compile fairly fast. So I am wondering if anyone has any insights on this - is the Android plugin or in general the Android devices not meant to handle such large apks? Is there anything else I need to configure or look into to get this packaged?

[android-developers] Transfer database file to Android
I'm porting an app that I've supported for many years on PalmOS PDAs. In that world, the user runs a Windows program on his PC that creates a PalmOS database file, which is then Hotsynced to the handheld for the PalmOS app to use. For Android, it should work in a similar way, with the user periodically updating the database on the Android device by regenerating it on his PC. So far, I've made the conversion on the Windows side to generate an SQLite database and can use adb push to transfer it to the emulator, where I've verified that I can run queries on it using the sqlite3 tool, etc. What I'm unclear on at this early stage is how the file transfer can be accomplished with an actual Android device. These files can tend to be rather large, so perhaps the SD card would be a good place to put them, but in any case I'm unclear on if there is any built-in or automated way to transfer files from a PC to an Android device. My users tend to be non-techy people and I can't trust them to manually copy the file to the correct location, if that's even possible. Another thought I've had is some way to store the converted file out in the cloud somewhere and then have my app retrieve it from there. Any ideas or suggestions on this would be appreciated!

I think the android team should pay more attention to that, say, improve the emulator performance and provide some other default ide other that eclipse. (the QT creator looks good) in addition, android should be more c++ friendly, because then millions of c++ projects can be easily ported to android. eclipse is just so so terrible -- You received this message because you are subscribed to the Google Groups Android Developers group.

Airplay is a pretty decent multi-platform SDK. http://www.airplaysdk.com/index.php It's not quite what you want, though.

[android-developers] Re: Weird sqlite behaviour. Can somebody explain?
Sorry if I reply so late, but I wasn't at home. I can't manage it
work. The cursor.getString() method returns me the string with the
quote.
I used single quote ' but I also tried using double quotes .
My method of stripping the quotes back works, but now I am so curious
of getting it work properly...
I also tried to open the source code but I didn't find it.
I'm pretty sure the quotes are not stripped when it retrieves the data
in CursorWindow (but I am quite new to this java stuff, I can be
wrong) whereas I got lost in the insert part (but it looks like it
prepares the statement with the data I pass to it).
If you want to check, I can write a simplified version of the code
that's not working for me.
I got a
public long addNumber(String number)
{
ContentValues contentValues = new ContentValues();
contentValues.put(NUMBER_DESC_KEY, number);
return db.insert(NUMBERS_TABLE, null, contentValues);
}
and a
public Cursor getAllNumbers () {
return db.query(NUMBERS_TABLE, new String[] {ROW_ID,
NUMBER_DESC_KEY},
null, null, null, null, null);
}
and this is the test that fails:
public void testAddnumberFails(){
String input = '+39123123231';
db.open();
db.addNumber(input);
db.close();
db.open();
Cursor c = db.getAllNumbers();
if(c.moveToFirst()){
do{
String number =
c.getString(DbAdapter.NUMBER_DESC_COLUMN);
assertTrue(Number different,
number.equals(input));
}while(c.moveToNext());
}
}
Where db is a DbHelper class as described in many tutorials.
The table was created with CALL_NUMBER_DESC_KEY field as a string.
DATABASE_NUMBERS_CREATE = create table +
NUMBERS_TABLE + ( + ROW_ID +
integer primary key autoincrement, +
NUMBER_DESC_KEY + string);;

[android-developers] service that maintains TTS
Hi. I have an application that relies on TTS to work in real time upon device events (such as new message\sms). To do that i start my service on device init and when i start it i start the TTS engine. Once started my broadcast receivers sends it IPC's to play whatever is needed. Of course if an ipc is sent to the service and it's not on i'll have o start it again, acquire the TTS again and pay the performance penalty that the sound will be played only seconds after the event. My question is, is there a better way to handle the TTS engine ? if i keep the TTS engine instance will it prevent other apps from using it ? if from a moment that event has occurred i need about 0-200 milli response, is there a solution other then a service that keeps a live instance of TTS engine that is already initialized ? 10x! ^^ -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Weird sqlite behaviour. Can somebody explain?
Read the documentation carefully:
In SQLite, the datatype of a value is associated with the value
itself, not with its container.
Any column in an SQLite version 3 database, except an INTEGER PRIMARY
KEY column, may be used to store a value of any storage class.
There is what they call affinity, but it does not affect how a value
is interpreted in the query statement, only conversions that occur
after it's initially interpreted.
I've not used the Android interfaces, but with the standard
java.sql.ResultSet updateString/getString interface there's no need to
explicitly quote string values, or strip the quotes on retrieval.
Here's the code I've used for constructing an INSERT statement (since
oddly none of the APIs support a ResultSet style interface for
INSERT):
StringBuffer stmt = new StringBuffer();
stmt.append(INSERT INTO );
if ((schemaName != null) (schemaName.length() 0)) {
stmt.append(schemaName);
stmt.append(.);
}
stmt.append(tableName);
stmt.append( VALUES ();
for (int i = 0; i columnValues.length; i++) {
if (columnValues[i] instanceof String) {
stmt.append(');
stmt.append(doubleQuotes(columnValues[i].toString()));
stmt.append(');
}
else {
stmt.append(columnValues[i].toString());
}
if (i+1 == columnValues.length) {
stmt.append());
}
else {
stmt.append(, );
}
}
(Implementing method doubleQuotes is left as an exercise for the
student.)

I need this as when an event of my C++ library arises, a method of Activity1 is called, and I need then to call a method of Activity2.

Although I think there is a way of making this work, I have to question why you would want to do this. It is the Java interface (including JSR-239)that is well tested in Android. Besides: if you use GLSurfaceView and override its methods, it really does do a lot of the work for you. What do you hope to gain by using the NDK here? What are you doing with OpenGL that would meet Google's description of good candidates for NDK work? Recall, http://developer.android.com/sdk/ndk/index.html#overview says: The NDK will not benefit most applications. ...

[android-developers] Re: What is a WeakReference?
You are correct. My wording did not make it clear: soft references are useful for memory-sensitive caches, weak references for canonicalized mappings. But as you point out, in the weak reference example that started this thread, weak references really do not buy you much, since the memory is going to get GC'd when the process is killed, anyway. So only in yet rarer cases, when that moment is too long postponed, will weak references be worth the effort.

That is, instead of simply continuing to use the soft/weak reference, it should make a strong reference to the same object, allowing this latter reference to either go out of scope or be set to null when it is done. You are referring to the code that Joseph Earl wrote above. That code snippet is NOT a proper way to use weak references; that cache should be using soft references. On the other hand, in the example blog post referred to by the OP, which uses weak references, that IS a proper way to use weak references. The main Activity already has a strong reference to the objects. The secondary thread does not need to create a strong reference; in fact, that would make the weak reference useless. But if we are making this strong reference, what was the point of using the weak/soft reference in the first place? Ah, that is the tricky thing about using them. Depending on when you can make and release the strong reference, they might not buy you much; they might not buy you anything at all. That is why they are not recommended for much outside of caches and normalized mappings. You are referring to a soft reference, not a weak reference. Soft references are good for caches. Weak references are definitely recommended for the idea given in the article, where the main thread has a strong reference, and the background thread has a weak reference. That way if the main thread is killed (i.e. the app is finished), if the background thread is still running then it won't prevent the weakly referenced objects from being destroyed. I also hate to throw this bit of information into the mix, but it should be known that Android will kill your process, and hence background threads anyways, when all your main threads have been destroyed (i.e. all your activities are finished, and there aren't any services running). This means that, even if you did have a background thread running, it would be killed, implying that weak references wouldn't help because everything is going to get killed anyways. That being said, there are still circumstances where the weak references matter: just because one activity is finished, doesn't mean all of your app's activities are necessarily finished. So it would be good if you went from your main activity into another sub-activity which began a download. But then the user presses back, because they don't want to bother waiting on the download. In that case your main activity is still alive, but the background thread is working on the sub-activity that was already finished. If that background thread had weak references, then that background thread would no longer be holding on to the resources of the sub-activity with strong references, and the system could GC those resources already, before the background thread dies. -Matt -Matt -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: What is a WeakReference?
As the author of the IBM Developerworks article I referenced mentions,
that is not good enough. The Garbage Collector runs on a different
thread, you have no control over when it will be called. It is quite
possible that just after you test for null, the GC is called, and it
is no longer valid. Not likely, but possible.
If instead you create a strong reference and use that, discarding it
when done, then you have shut the door on a really nasty transient
bug.
Or perhaps the version of 'ref()' you found did this for you? What
package did you find it it?

Yes, you must guard any use of the WeakReference by taking the ref()
of it, testing that for null, and then proceeding to use the result of
the ref() if not null. The size of the guarded sections is up to
the programmer -- if too large then the object will never get deleted,
if too small then the code gets chopped up.

Suppose you had a long list of images. As the user scrolled down you
load the images from the net, and then display them.
To avoid having to reload the images again if the user scrolls back
up, you put the images in a cache (probably something like a
MapString, Drawable)
However because it is a long list you don't want to run into an out of
memory situation if the user scrolls very far down and lots of images
are put in the cache.
So instead of storing the Drawables directly in the map, you create a
MapString, WeakReferenceType (although I would use SoftReference
for the purpose described here).
This means that if Android is going to encounter an out of memory
situation it will clear all of the Soft/Weak references (and thus
hopefully avoid running out of memory). You will have to load the
images again since your cache has been cleared, but this is far better
than your application running out of memory and crashing.
So you do something like:
// caching an image
MapString, SoftReference cache = new HashMapString,
SoftReferenceDrawable();
cache.put(http://mysite.com/images/1.jpg;, new
SoftReferenceDrawable.put(myDrawable));
// retrieve an image
if (cache.containsKey(url)) {
// looks like we have this image cached
Drawable drawable = cache.get(url).get();
if (drawable == null) {
// the softreference has been cleared by the GC, reload the
image
} else {
// softreference is still valid, got our image
}
}
Essentially a weak reference is a weaker reference than a soft
reference - the GC should free weak references to regain memory before
soft references.
I think that's (mostly) correct, hope it helps.

[android-developers] Re: What is a WeakReference?
If the garbage collector deletes an object I have a hard reference
to, it's broken. Doesn't matter if it runs in a different thread or a
different country. Once I have executed ref() and stored the result
somewhere in my VM (in stack or in another object) that object cannot
be deleted until I overwrite the value.

tables. When I do a query (either with rawQuery or

table. Does anybody know how to do a query on 2 tables that have been
joined on a key value?
some code
public void onCreate(final SQLiteDatabase database) {
String sqlCreate =
CREATE TABLE IF NOT EXISTS Catch (
+ ID integer primary key
autoincrement,
+ GPSLON FLOAT,
+ GPSLAT FLOAT,
+ TimeTIMESTAMP,
+ BaitID INTEGER,
+ RigsID VARCHAR,
+ FishID VARCHAR,
+ SyncStatus INTEGER
+ );;
database.execSQL(sqlCreate);
sqlCreate =
CREATE TABLE IF NOT EXISTS bait (
+BaitID integer primary key
autoincrement,
+SyncStatus INTEGER,
+BaitNameVARCHAR unique);;
database.execSQL(sqlCreate);
sqlCreate =
CREATE TABLE IF NOT EXISTS rigs (
+RigsID integer primary key
autoincrement,
+SyncStatus INTEGER,
+RigsNameVARCHAR);;
database.execSQL(sqlCreate);
sqlCreate =
CREATE TABLE IF NOT EXISTS fishSpecies
(
+FishID integer primary key
autoincrement,
+SyncStatus INTEGER,
+FishName VARCHAR);;
database.execSQL(sqlCreate);
}
private long addBait(final Catch c) {
long id=-1;
Cursor data = db.query(bait,
null,
BaitName = '+c.baitText+',
null,
null,
null,
BaitName DESC);
if (data!=null) {
if (data.moveToFirst()){
id = data.getInt(0);
}
}
data.close();
if (id==-1){
final ContentValues initialValues = new ContentValues();
initialValues.put(BaitName, c.baitText);
initialValues.put(SyncStatus, c.syncStatus);
id = db.insertOrThrow(bait, null, initialValues);
}
return id;
}
public long addCatch(final Catch c) {
long baitId = addBait(c);
final ContentValues initialValues = new ContentValues();
initialValues.put(GPSLON,c.lon);
initialValues.put(GPSLAT, c.lat);
initialValues.put(Time, c.time.toString());
initialValues.put(BaitID, baitId);
initialValues.put(SyncStatus, c.syncStatus);
final long addedRow = db.insertOrThrow(Catch, null,
initialValues);
return addedRow;
}
public Cursor getAllMyFish() {
SQLiteQueryBuilder builder = new SQLiteQueryBuilder();
builder.setTables(Catch Bait);
Cursor c = builder.query(db, new String[]{}, null, new
String[]{},
null, null, null);
return c;
}
It is the cursor that is returned from getAllMyFish() that I want to
have fields from both Catch and Bait but I only get fields from Catch
when I look at the values returned from the cursor's getColumnName()

[android-developers] Populating child list in Expandable lists using dynamic multidimensional arrays
Hello Gurus, I am using a simple expandable list that is populated by two arrays ( group array for the groups and a multi dimensional children array for the child). The arrays are built dynamically in the program and some group items have more children than others. So I end up defining the highest number as the array size for the multidimensional child array. After populating the child array, some positions are left null, as there are no values for those group items (explained above). When I associate this with the expandable list adapter, the getChildView method throws a nullpointer exception when it comes across a position in child array that does noto have value. I have two questions: 1. Can I make the base adapter skip the shildview method if the value in that child is null? The current implementation of getchildView method has to return a view and even if I suppress the nullpointer exception, it adds a blank element in the child position in the list. 2. Is there a better way of associated multidimensional arrays that are populated at run time? The current set of examples only use hardcoded string array values. Even the cursor adapters examples use very basic setup. thank you so much for your attention and response.

[android-developers] Re: Large jars in Android
Hi Kumar, here they are: Bouncycastle jdk14 Mortbay w3cdom javaxservlet they are needed by sun's jxta to compile - the resulting jxta jar is about 1.8MB and all jars together imported into my app are close to 5.2MB.

Originally I had a number of 3rd jars that I was importing into the Android project. The general concensus I got was that I needed to find the source for them and compile them in Android - well I kicked my behind and did all that and finally I have all jars in place for my Android app. The compilation and packaging of apk of the app with those jars sitting in the libs dir of the app takes 10-12 mins and towards the end it gives an Eclipse internal error and it quits! I tried doing this outside Eclipse using ant and still the same result. I have the java heap params jacked up for -xmx and -xms to 256MB and still no luck. The jars sum up to 6MB and the actual app to 0.25MB. The individual library directories that use to compile each of the 3rd jars compile fairly fast. So I am wondering if anyone has any insights on this - is the Android plugin or in general the Android devices not meant to handle such large apks? Is there anything else I need to configure or look into to get this packaged?

[android-developers] Re: allign text vertically in a text view
Not layout_gravity, but only gravity. There are several other types of gravity which you can apply to any view. center|center_vertical|center_horizontal And there are a few others. Try those out. -Kumar Bibek http://tech-droid.blogspot.com On Jul 26, 2:38 am, harshe hars...@gmail.com wrote: I have a textview placed vertically in an activity..
