[android-beginners] Re: IOException with BufferedReader
Hi Yousuf,
Thank you very much for the answer. However, I don't know in which
directory i should put the file? I don't want to save the file from my
application - it should just be there when the application is
installed. I don't think I can access this file with the
context.openFileInput() method? Or am I wrong?

[android-beginners] Re: IOException with BufferedReader
Hi again,
I've just tried putting a simple file with the Hello, world text
into the raw folder, and this works as it should. The other file is
1.1 megabyte. Can the error be caused because of the size?

Hi Kaloer,
The procedure is as follows:
1. create a raw folder,
2. place a file.(txt or regular file with no extension) in the raw folder.
3.write the code as said earlier.
4 one more thing that you can do is push the file through eclipse's ddms to
data/data/your application dir/files directory.
(Your file in the DDMS will be updated not the one contained in /res/raw/
folder so look for the size of the file present in ddms under
/data/data/com.app.files/files/ )
5 path to be specified: just give the file name that is present in the raw
folder.
if the name of file is sample.txt which is present in /res/raw/ folder
FileInputStream fin = context.openFileInput(sample.txt); // if used within
a adapter class or somewhere outside the activity class
if you are using this within the activity it should be
FileInputStream fin = openFileInput(sample.txt);
I guess step 4 is needed for the first time since your read is performed
before your write.
if you are writing before reading then the FileOutputStream object either
writes to a existing file or creates a new one( FileInputStream object
cannot create a new file).
Do remember that raw folder has a limit to the data that it can contain so
files with large amount of data cant be stored there.
For your convenience I am attaching my filehandling projected that reads and
writes to file. This is a working example.
for some reason if this is not working try using permissions.
read_owner_data
write_owner_data
write_external_storage
but these permissions are for files stored on /sdcard/filename
Hope this would help.

Yousuf.

I have an Dialog with a custom view. This view has a SurfaceView which

[android-beginners] Intent.getIntExtra doesn't find value
Hi,
I'm modifying the default Alarm Clock application source, but I have a
problem sending an Integer value with an Intent. This is where I put
the snooze_duration value into the Intent:
static void enableAlert(Context context, int id, String label,
long atTimeInMillis, int dismissBehaviour, int
snoozeBehaviour, int
snoozeDuration) {
AlarmManager am = (AlarmManager) context
.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(ALARM_ALERT_ACTION);
if (Log.LOGV)
Log.v(** setAlert id + id + atTime +
atTimeInMillis);
intent.putExtra(Alarms.ID, id);
intent.putExtra(Alarms.LABEL, label);
intent.putExtra(Alarms.TIME, atTimeInMillis);
intent.putExtra(Alarms.DISMISS_BEHAVIOUR, dismissBehaviour);
intent.putExtra(Alarms.SNOOZE_BEHAVIOUR, snoozeBehaviour);
//HERE:
intent.putExtra(Alarms.SNOOZE_DURATION, snoozeDuration);
PendingIntent sender = PendingIntent.getBroadcast(context, 0,
intent,
PendingIntent.FLAG_CANCEL_CURRENT);
if (true) {
am.set(AlarmManager.RTC_WAKEUP, atTimeInMillis, sender);
} else {
// a five-second alarm, for testing
am.set(AlarmManager.RTC_WAKEUP,
System.currentTimeMillis() + 5000,
sender);
}
setStatusBarIcon(context, true);
Calendar c = Calendar.getInstance();
c.setTime(new java.util.Date(atTimeInMillis));
String timeString = formatDayAndTime(context, c);
saveNextAlarm(context, timeString);
}
But when I try reading it, it sets the defaultValue instead. The other
values works as they should, but the snooze_duration doesn't. I get
the values in the OnCreate() method in the activity started by the
Intent:
Intent i = getIntent();
mAlarmId = i.getIntExtra(Alarms.ID, -1);
mDismissBehaviour = i.getIntExtra(Alarms.DISMISS_BEHAVIOUR,
0);
mSnoozeBehaviour = i.getIntExtra(Alarms.SNOOZE_BEHAVIOUR, 0);
mSnoozeDuration = i.getIntExtra(Alarms.SNOOZE_DURATION, 10);
Why doesn't this work? I have tried debugging, and it does put the
correct integer value in the Intent.putExtra method.
Thank you very much!

[android-beginners] LayoutParams.ScreenBrightness problem
Hi,
In my last update, I can't change the screen brightness anymore. I
have not changed the code snippet where the brightness is set. Can it
be caused by Donut?
Here's my code, placed in the onResume() method:
if (alwaysBacklight) {
WindowManager.LayoutParams lp =
getWindow().getAttributes();
final PowerManager pm = (PowerManager) getSystemService
(Context.POWER_SERVICE);
this.mWakeLock = pm.newWakeLock(
PowerManager.SCREEN_BRIGHT_WAKE_LOCK
|
PowerManager.ACQUIRE_CAUSES_WAKEUP, clockTag);
this.mWakeLock.acquire();
int value = screenBrightness;
if (value 5)
value = 5;
lp.screenBrightness = (float) value / 100;
getWindow().setAttributes(lp);
getWindow().setFlags
(android.view.WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON, 0);

All callbacks from Android need to be done quickly. This includes
starting services. Only work done on threads of your own creation can
take longer.
I've attached the log (which do have a line with

Something in your service (onCreate() or onStart(), most likely) is
taking too long.
Can it help if I do the xml parsing in a thread?
Yes. Use AsyncTask or something to move the XML parsing off the thread
used for the callback.

[android-beginners] Re: Using Buttons in home screen widgets
Thanks for the answer,
I have tried working with my code and looking at your widget's source.
Event though, I can't get it working. I do not use a service as you,
but my code looks like this:
package com.kaloersoftware.kaloertimerwidget;
import android.app.PendingIntent;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.Context;
import android.content.Intent;
import android.widget.RemoteViews;
import android.widget.Toast;
public class KaloerTimer extends AppWidgetProvider {
@Override
public void onUpdate(Context context, AppWidgetManager
appWidgetManager,
int[] appWidgetIds) {
Intent i = new Intent(context, KaloerTimer.class);
PendingIntent pi = PendingIntent.getBroadcast(context,0, i,0);
RemoteViews rv = new RemoteViews(context.getPackageName(),
R.layout.main);
rv.setOnClickPendingIntent(R.id.startBtn, pi);
}
@Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
Toast.makeText(context, It Works, Toast.LENGTH_SHORT).show();
}
}
Btw, is there any way to debug a widget? Nothing happens when I place
a breakpoint in the onUpdate() method.

but I don't really know how to use them.
Therefor, I have some questions:
1) How do I set an onClickListener (or an OnClickPendingIntent() ) for
the button?
In the tutorial you cite, Jeff Sharkey uses setOnClickPendingIntent() for
clicks on the widget as a whole. However, that works just as well for
clicks just on a button -- provide the button's ID as the first parameter.
1,2) where do I set this? There is no onCreate() method..
You would set it wherever you are building your RemoteViews.
2) This method starts an Intent, but how do I use an Intent to just
run a method? I do not want to start any activity.
You can't use an Intent to just run a method. However, an Intent does
not need to start an activity. Jeff's example uses
PendingIntent.getActivity() to launch an activity, but you could use
PendingIntent.getService() or PendingIntent.getBroadcast() to communicate
with other components.
I can point you at some source code for an app widget that demonstrates
the use of buttons communicating with a back-end service -- visit:
http://commonsware.com/AdvAndroid/
and download the source code to my one book. In the ZIP file, you will
find an AppWidget/TwitterWidget project. As the name suggests, it is a
widget that displays the latest tweet in your friends' timeline. It also
has a button to refresh and a button to configure the widget. The
configure button pops an activity, but the refresh button triggers the
same logic as is invoked when updateTimeMillis elapses.

You're right -- I skimmed it too quickly.
It's actually a bit more complicated than that. The flow is:
begin-transaction
insert 100 rows worth of stuff
set-transaction-successful

I have tried to use a txt file and put the data to a List, but this is
too slow because it needs to read all the data. But Maybe I should
create a table in the database for each letter (and every second, if
necessary) , so that it doesn't need to read all the data.

There are other alternatives, it all depends on your data and how you
want to use it so you might want to help us here.
Example: you mention words, just not any string, so your data might
be a dictionary.
Then in this case you could simply use a binary file, in your own
format, packaged in your project/res/raw directory, which you can
retrieve
withhttp://d.android.com/reference/android/content/res/Resources.html#ope...)
-- the file is added uncompressed to your APK but the APK itself is a
zip file, which is why you get an input stream. That also means if you
need direct random access you'll probably want to write it somewhere,
such as on the sdcard.
Make sure to write an index for fast lookup, for example the offset of
words starting by A, by B, etc. You will probably need to experiment a
bit to get a tradeof between simplicity of the index and lookup time,
e.g. a tree will have faster lookup times but is more tricky to get
right, etc.

You're right -- I skimmed it too quickly.
It's actually a bit more complicated than that. The flow is:
begin-transaction
insert 100 rows worth of stuff
set-transaction-successful
and do that whole block 1000 times for 100,000 words.
So you're probably going to wind up with something like:
while ((line=input.readLine())!=null) {
DB.beginTransaction();
DB.execSQL(...);
for (int i=0;i99 (line=input.readLine())!=null; i++) {
DB.execSQL(...);
}
DB.setTransactionSuccessful();
}
plus an appropriate try/catch in there.
However, bear in mind that this will still take a very long time, so
unless you're trying this for educational purposes, I'd move along to
one of the other options.

[android-beginners] Best way to add 100.000 words to database
Hi,
I am developing an application that, as the first thing, puts all
lines from a txt-file to a sqlite database. There is about 100.000
words that should be added to the database, and this takes almost an
hour to do.
Is there a better way to do this, fx. to have a database in the res/
raw resources if it is possible.
This is my currently way to do it:
public void getWords(final Context context, final InputStream aFile) {
try {
InputStreamReader reader = new InputStreamReader(aFile,
Charset.forName(UTF-8));
BufferedReader input = new BufferedReader(reader);
try {
DB = context.openOrCreateDatabase(DATABASE_NAME, 1,
null);
DB.execSQL(DELETE FROM english);
String line = input.readLine();
int i = 0;
while (( line = input.readLine()) != null){
try {
DB.execSQL(INSERT OR IGNORE INTO english(word)
VALUES
(' + line + '));
}
catch (Exception e) {
Log.e(kaloer, e.getMessage());
}
if(i % 100 == 0) {
Log.d(progress,
Integer.toString(i));
try {
Thread.sleep(100);
}
catch(InterruptedException e) {
}
}
i++;
}
} catch (IOException e) {
e.printStackTrace();
}
finally {
try {
input.close();
} catch (IOException e) {
e.printStackTrace();
}
DB.close();
}
}
return;
}
Thank you very much,

[android-beginners] Re: Best way to add 100.000 words to database
How does the transaction work? I'm new to databases. I found this on
the android documentation
db.beginTransaction();
try {
...
db.setTransactionSuccessful();
} finally {
db.endTransaction();
}
Should I implement it like this:
int i = 0;
while (( line = input.readLine()) != null){
if(i % 100 == 0) {
DB.beginTransaction();
Try {
DB.execSQL(INSERT OR IGNORE INTO
english(word) VALUES
DB.setTransactionSuccessfull
();
} Finally {
DB.endTransaction();
}

}
1. Right now, you are doing 100,000 transactions. Wrap your own
transaction around the INSERT loop, one for every 1,000 words or something.
2. Create the SQLite database on your development PC and package it as a
raw resource or asset. Then, before you need it, copy it from the
resource to the appropriate databases/ directory by reading from a raw
resource or asset stream. Downside #1: if SQLite ever changes its
database format, you're in trouble. Downside #2: you take up double the
memory.
3. Create the SQLite database on your development PC and download it off
the Internet before first use. Downside: if SQLite ever changes its
database format, you're in trouble.
4. Use some other data structure and library than SQLite.

[android-beginners] Re: Open txt file from res/raw
I need to read every line of the txt-file, and I currently have this
method:
public ListString getWords(File aFile) {
ListString contents = new ArrayListString();
try {
BufferedReader input = new BufferedReader(new FileReader
(aFile));
try {
String line = null;
while (( line = input.readLine()) != null){
contents.add(line);
}
}
finally {
input.close();
}
}
catch (IOException ex){
ex.printStackTrace();
}
return contents;
}
I have tried to edit it, but I don't get the data I want. The first
entry of the contents-list is #!/usr/bin/env xdg-open and none of
them is what the txt-file contains:
public ListString getWords(InputStream aFile) {
ListString contents = new ArrayListString();
try {
BufferedReader input = new BufferedReader(new InputStreamReader
(aFile));
try {
String line = null; //not declared within while loop
while (( line = input.readLine()) != null){
contents.add(line);
}
}
finally {
input.close();
}
}
catch (IOException ex){
ex.printStackTrace();
}
return contents;
}
Maybe I do something wrong - I'm new to java.

[android-beginners] Force alarm sound
Hi, Is it possible to force the volume up? I have an alarm that should wake the user even if the phone is on silent mode.. Is that possible?

[android-beginners] A lot of graphics in drawable-folder
Hi, I have plenty of image files in my drawable folder because my application has different skins. This makes it very unmanageable. But is there a better to organize the graphics, like folders, groups or such things? Or is it a good idea to not use the drawable resource, but instead create a xml file in the application directory for each skin with the image-links? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] Call method from Broadcast Receiver
Hi, Is it possible to call a method that finds a view by id and changes it, from a broadcast receiver? For example: I have the default class that extends Activity and contains a setContentView method. In the layout i have set as the contentView, i have a TextView. Then i have a method that should change the text to something, but this should be called from a broadcast receiver and not in the default class. But when the broadcast receiver-class extends BroadcastReceiver it cannot use the findViewById method because it requires the class to extend the Activiy class. I have tried to initialize the default class, but then the application stops unexpectedly when the broadcast receiver is called. How can i call the method? //Kaloer --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] Best way to update clock
Hi,
I have a method in my application which updates a clock. But what is
the best way to run the method so that it automatically updates the
clock?
Should i use a Timer (i have heard, that it does not work very well in
android) or what should i use?
I will be glad if you could please post a simple example :-)
Currently the part of my code that contains the thread looks like
this, but it does not work (I don't get an exeption, but it simply
does not run the updateTime() method.) :
public class NightClock extends Activity {
private final ScheduledExecutorService scheduler =
Executors.newScheduledThreadPool(1);
ScheduledFuture? updateHandle;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Calendar cal = Calendar.getInstance();
updateTime();
long toTimerStart = ( 60 - cal.get(Calendar.SECOND) ) * 1000;
Runnable mUpdateTimeTask = new Runnable() {
public void run() {
updateTime();
}
};
updateHandle = scheduler.scheduleAtFixedRate(mUpdateTimeTask,
toTimerStart, 1000, TimeUnit.MILLISECONDS);
}
Thank you very much!

[android-beginners] Re: Get phone number from sms
Hi Avron,
Thank you very much, just what i was looking for :)

Kaloer,
You need to set a URI to the SMS Inbox Content and then create a
cursor (i.e a query to the the SQLLite DB) and iterate over it.
If you are in your activity, it would be somthing like
this.getContentResolver().query(
Uri.parse(content://sms/inbox), null, null,
null, null);
You then have access to the full SMS content and phone number etc.
Hope this helps !

Hi,
Is it possible to get the phone number of a received sms within code?
Look at this example at the if-statement:
@Override
public void onReceive(Context context, Intent intent) {
Bundle bundle = intent.getExtras();
Object messages[] = (Object[]) bundle.get(pdus);
SmsMessage smsMessage[] = new SmsMessage[messages.length];
for (int n = 0; n messages.length; n++) {
smsMessage[n] = SmsMessage.createFromPdu((byte[]) messages
[n]);
}
if([HOW DO I GET THE NUMBER]) {
Toast toast = Toast.makeText(context, New SMS: + smsMessage
[0].getMessageBody(), Toast.LENGTH_LONG);
toast.show();
}

Thank you very much!

Thank you, I already had tried the getOrientation method, but did not know how to use it.

[android-beginners] Change TextView text in code
Hi, I have made a layout in Xml, which includes a TextView. The TextView should show some text that is found in a database. Therefore, i cannot find the text by using the @string/something. How can i define the text from my code, without creating the whole layout in code? My TextView has the id currentRankLabel. I think i shall do something like this: View currentRankText = this.findViewById(R.id.currentRankLabel); currentRankText.setText(some text); Best Regards, Kaloer --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.
