[android-developers] Don't recieve Wi-Fi connection change intent when device screen is blank
I currently listen for changes in the Wi-Fi in my Android application and
for the most part it works OK, however when the user has there device is
idle/sleep mode, as in when the screen is blank. If they walk into a Wi-Fi
area and automatically connect I don't get the intent until the user has
turned on the screen. This is not good and leads to complaints about my
application. Can anyone help with why I don't get the intent until the
screen wakes up?
Here is my code:
BroadcastReciever:
public class WifiReciever extends BroadcastReceiver{
@Override
public void onReceive(Context arg0, Intent arg1) {
String action = arg1.getAction();
if (!action.equals(ConnectivityManager.CONNECTIVITY_ACTION)){
return;
}
if (!noConnectivity)
{
if (aNetworkInfo.getType() == ConnectivityManager.TYPE_WIFI)
{
//Handle connected case
Log.e(E, GOT CONNECTION);
}
}
else
{
if (aNetworkInfo.getType() == ConnectivityManager.TYPE_WIFI)
{
//Handle disconnected case
Log.e(E, LOST CONNECTION);
}
}
}
If a running Service I have that as a variable:
WifiReciever mConnectionReceiver;
And I start and stop the receiver in the service with the following calls:
private synchronized void startMonitoringConnection()
{
IntentFilter aFilter = new
IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION);
registerReceiver(mConnectionReceiver, aFilter);
}
private synchronized void stopMonitoringConnection()
{
unregisterReceiver(mConnectionReceiver);
}
I call a WakeLock to make sure that I am getting CPU time like this:
pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, CicCPULock);
wl.acquire();
However even with all that I never receive the Connectivity changed intent
if the screen is blank, it works 100% of the time when the screen is on bit
if I a user walks into a Wi-Fi are and connects when the screen is blank I
fail to get the intent, is anyone aware of something I am missing?

[android-developers] Android - use multiple Activities within a TabActivity what's the solution?
I currently have a TabActivity which has 4 tabs, within one of the tab's I want to be able to move forward and back between 4 different Activities. However if I try to start a new Activity now it removes the TabActivty and starts a whole new Activity with no tab bars. I have read about using view groups but that this is not best practice and also about using a view flipper but this doesn't seem to let me switch between different Activities only change the views within the Activity. I can't implement back functionality for exa,ple. Can anyone point me in the right direction as to what I should be looking for as a solution to this? Some more information: Within the TabActivity my first screen will be a ListView that contains 4 rows, then selecting one of these will in turn load another ListView with 2 rows again within the TabActivity and then the 3rd screen will just contain some text depending on which option the user chose again within the Tab Activity. Is a ViewFlipper the best solution here? It seems to me that it will require a lot of coding within one Activity if I use the ViewFlipper? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Strange behavior after signing build with release keystore
Having some really strange bugs with my Android application at the minute, it I run it from Eclipse it runs fine, pretty much perfect. It contains a login screen that I can access and get to my main screen fine when running through Eclipse. When I press the home key and return to my application it returns to the last position (Activity) the application was in. However when I release sign a build and deploy it on the device it has different behavior,after going through the login screen when I press home and then return to the application the login screen always appears. Code is identical in both builds, only difference is one is signed with the default debug keystore while the other is signed with my own release keystore. Has anyone come across this?

[android-developers] Eclipse wont regenerate files since downloading the 2.3 SDK
I have recently downloaded the add on to Eclipse for the 2.3 SDK. My minSDK is 2.1update-1. Previously I only had up to the 2.2 SDK and I could change my XML files and drawables without hassle and the generated R.java file would regenerate properly. The same if I changed my aidl files, the stubs would regenerate properly. However since the upgrade to 2.3 SDK I cant change or add any XML files or drawables or aidl files as they wont regenerate causing all sorts of issues. I have googled and tried all sorts of suggestions such as: Using clean. Deleting the gen files and rebuilding (Just leaves an empty Gen folder) Using non automatic build Using the new Formating parameter in Strings.xml However none of them work. Is there something I've missed that I have to do to get the regeneration working for 2.3 SDK? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Android intent filter for SMS and call?
I am trying to register my Activity so that it can be used by the Activity chooser/picker allowing a user to choose whether or not to select my application/Activity to complete what they are trying to do. I want to provide the option for the user to be able to select my application when they want to send an SMS message and when they want to place an outgoing call, to try to achieve this I added the following pieces of code within my Activity tags in my manifest: intent-filter action android:name=android.intent.action.SENDTO / category android:name=android.intent.category.DEFAULT / data android:mimeType=text/plain / /intent-filter intent-filter action android:name=android.intent.action.NEW_OUTGOING_CALL / category android:name=android.intent.category.DEFAULT / /intent-filter However the Activity chooser never appears and the native apps are used without providing a choice to the user. Can anyone see where I am going wrong? EDIT: I have figured out I need to add data android:scheme=sms / data android:scheme=smsto / for the SMS message but what do I use for the outgoing call? EDIT 2: I have tried the following for the outgoing call: intent-filter action android:name=android.intent.action.VIEW / action android:name=android.intent.action.DIAL / category android:name=android.intent.category.DEFAULT / category android:name=android.intent.category.BROWSABLE / data android:scheme=tel / /intent-filter But again with no luck, has this been blocked from 1.6 on? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] How to decrypt an XML file?
0 down vote favorite
I am trying to to download and decrypt an encrypted XML file.
I have implemented the download part and have tested with an
unencrypted file and it works fine.
However I now need to be able to download an XML file that has been
encrypted using AES and the key
So I am only concerned with decryption as the encryption on the XML
file is already done.
Here is my code so far:
public NodeList getXMLDoc(){
URL url;
NodeList nl = null;
try{
String xmlFeed = context.getString(R.string.xml_feed);
try {
url = new URL(xmlFeed);
URLConnection urlConnection;
urlConnection = url.openConnection();
HttpURLConnection httpConnection = (HttpURLConnection)
urlConnection;
int responseCode = httpConnection.getResponseCode();
if(responseCode == HttpURLConnection.HTTP_OK){
String bytes = toHex();
SecretKeySpec skeySpec = new
SecretKeySpec(toByte(bytes), AES);
try {
c.init(Cipher.DECRYPT_MODE, skeySpec);
//c.doFinal();
} catch (InvalidKeyException e) {
e.printStackTrace();
}
InputStream in = httpConnection.getInputStream();
CipherInputStream cis = new CipherInputStream(in,
c);
DocumentBuilderFactory dbf;
dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document dom = db.parse(cis);
Element docEle = dom.getDocumentElement();
nl = docEle.getElementsByTagName(TAG_CHAR);
}
}
catch (MalformedURLException e) {
e.printStackTrace();
}
catch (IOException e) {
e.printStackTrace();
} catch (ParserConfigurationException e) {
e.printStackTrace();
} catch (SAXException e) {
e.printStackTrace();
}
}
finally{
}
return nl;
}
At the minute I am trying to decrypt the whole file using
CipherInputStream is this the correct approach?
My code above gives me the following exception:
WARN/System.err(5274): java.io.IOException: last block incomplete in
decryption
Is this a setup error or what might be causing this error?
Are there any tutorials on how to decrypt an XML file in Android/Java?
Am I going in the right direction as to how to decrypt the file or is
my code completely wrong?

[android-developers] how to get specific preference in Java code from an XML preferences file?

[android-developers] AsyncTask doesn't run sometimes despite state returning RUNNING?
In my application I use an AsyncTask on start up of my Activity to
fetch the ringtone of a particular contact.
It works normally but I have noticed that if the application is
stopped twice before the AsyncTask gets to the doInBackground method
then when the Activity starts again the AsyncTask fails to run
properly, only getting to the onPreExecute() method.
Here is my code:
The AsyncTask itself:
---
private class SelectRingtoneTask extends AsyncTaskString, Void,
Void {
// can use UI thread here
protected void onPreExecute() {
Log.d(cda, Into selectRingToneTask -
onPreExecute() - +
selectRingtoneFinished);
}
// automatically done on worker thread (separate from UI
thread)
protected Void doInBackground(final String... args) {
Log.d(cda, Into selectRingToneTask -
!!!);
getRingTone();
return null;
}
// can use UI thread here
protected void onPostExecute(final Void unused) {
selectRingtoneFinished = true;
Log.d(cda, Into selectRingToneTask - onPostExecute -
+
selectRingtoneFinished);
}
}
---
Where I call the AsyncTask on start up:
---
if(srtt == null){
srtt = new SelectRingtoneTask();
Log.d(cda, RingTone - + srtt.getStatus());
}
srtt.execute();
---
The problem occur's when I start the activity and close the Activity
before the AsyncTask finishes, if this happens once, it seems to be
fine but after it happens a second time the AsyncTask will only ever
get to the onPreExecute() method and will never complete again until
the application is force stopped and restarted.
Has anybody got any idea why this would be happening?

[android-developers] how to make sure my Service is restarted?
0 down vote favorite
I have an Android application with a background running Service.
When the Service crashes or gets killed by Android I can see that
Android tries to restart it again.
However the Service never actually restarts, I can see Android
scheduling the restart but it new actually happens.
My code is as follows:
--
@Override
public void onCreate() {
String ns = Context.NOTIFICATION_SERVICE;
mNotificationManager = (NotificationManager) getSystemService(ns);
mTelephonyManager =
(TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
audio_service = (AudioManager)
getSystemService(Context.AUDIO_SERVICE);
}
// This is the old onStart method that will be called on the pre-2.0
// platform. On 2.0 or later we override onStartCommand() so this
// method will not be called.
@Override
public void onStart(Intent intent, int startId) {
handleCommand(intent);
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
handleCommand(intent);
// We want this service to continue running until it is explicitly
// stopped, so return sticky.
return START_STICKY;
}
void handleCommand(Intent intent) {
running = true;
mTelephonyManager.listen(new IncomingListener(),
PhoneStateListener.LISTEN_CALL_STATE);
}
--
Is there something missing in my code to allow the Service be
restarted?

[android-developers] Slider devices cause Activities to reset…

I understand why this is done when the display is being switched to landscape view but why does this happen when I specifically dont want my activity to switch view, its essentially killing and restarting the activity for no reason. Is it the same on 2.x devices? Is there something I'm missing to stop it happening?

[android-developers] Key Dispatching Timed Out
In my Android application I am getting a very strange crash, when I
press a button (Image) on my UI the entire application freezes and
after a couple of seconds I getthe dreaded force close dialog
appearing.
Here is what gets printed in the log:
---

This is the code for the Button (Image):
---
findViewById(R.id.endcallimage).setOnClickListener(new
OnClickListener() {
public void onClick(View v) {
mNotificationManager.cancel(2);
Log.d(Handler, Endcallimage
pressed);
if(callConnected)

SystemClock.elapsedRealtime()
- stopWatch.getBase();
try {
serviceBinder.endCall(lineId);
} catch
(RemoteException e) {
e.printStackTrace();
}
dispatchKeyEvent(new
KeyEvent(KeyEvent.ACTION_DOWN,KeyEvent.FLAG_SOFT_KEYBOARD));
dispatchKeyEvent(new
KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_BACK));
}
});
---
If I comment the following out the pressing of the button (image)
doesn't cause the crash:
---
try {
serviceBinder.endCall(lineId);
} catch (RemoteException e) {
e.printStackTrace();
}
---
The above code calls down through several levels of the app and into
the native layer (NDK), could the call passing through several objects
be leading to the force close? It seems unlikely as several other
buttons do the same without issue.
How about the native layer? Could some code I've built with the NDK be
causing the issue?
Any other ideas as to what the cause of the issue might be?

[android-developers] How do I capture and loop video to the screen?
I was wondering if anyone knows of a tutorial explaining how to capture the video from the camera on an Android device and then display the video in real time on the screen? I have looked up MediaRecorder, MediaPlayer, Videoview but they all seem concerned with recording audio/video to a file or playing audio/ video from a file or a URL.

[android-developers] How to change target build on Android project?
I currently have an Android project in Eclipse. I created it with a target build of 1.5 (sdk 3). Now I want to change it so that it has a minSdk of 3 and targetSdk of 8. To do this I see that I must build against the newest SDK (2.2) To do this in Eclipse I right click on my project, go to properties, click on Android and change the project build target to Android 2.2 and click apply and then ok. However this appears to have no affect and when I try it again the target build is set back at Android 1.5.

[android-developers] Android - Java Observer not working
I am having some trouble with implementing my own observer in Java on
the Android platform.
I have created a class call NetworkPathJni that uses an Observer
interface class called NetworkPathJniObserver to notify other objects
of changes.
Here is the code for NetworkPathJni.java
---
public class NetworkPathJni {
NetworkPathJniObserver networkPathJniObserver;
public NetworkPathJni(NetworkPathJniObserver aObserver){
networkPathJniObserver = aObserver;
Log.d(Phone, NetworkPathJni Created );
}
public void NetworkPathStateChanged(int aAvailabilityState){
Log.d(Phone, NetworkPathStateChanged new state = +
aAvailabilityState );
TAvailabilityState availabilityState =
intToAvailability(aAvailabilityState);
Log.d(Phone, Is SipNetworkPath alive? +
networkPathJniObserver.isAlive());
networkPathJniObserver.NetworkPathStateChanged(availabilityState);
Log.d(Phone, NetworkPathStateChanged end );
Log.d(Phone, Is SipNetworkPath alive? (2) +
networkPathJniObserver.isAlive());
}
---
And here is the code for the observer
---
public interface NetworkPathJniObserver {
void NetworkPathStateChanged(TAvailabilityState aAvailabilityState);
boolean isAlive();
}
---
The observer is implemented as follows in a class called
SipNetworkPath
---
public class SipNetworkPath implements NetworkPathInterface,
NetworkPathJniObserver{
NetworkPathObserverInterface observer;
NetworkPathJni networkPathJni;
public SipNetworkPath(NetworkPathObserverInterface aObserver){
domainType = aDomainType;
observer = aObserver;
networkPathJni = new NetworkPathJni(this);
Log.d(Phone, SipNetworkPath created );
}
//NetworkPathJniObserver
@Override
public void NetworkPathStateChanged(TAvailabilityState
availabilityState) {
Log.d(SipNetworkPath, SipNetworkPath - Do networkpathstate
changed!);
}
@Override
public boolean isAlive() {
return true;
}
---
And SipNetworkPath is instanciated as follows
---
public class WifiNetworkPath extends SipNetworkPath{
public WifiNetworkPath(NetworkPathObserverInterface aObserver) {
super(aObserver);
}
---
The logging shows that both NetworkPathJni and SipNetworkPath get
created and that NetworkPathStateChanged(int aAvailabilityState) is
called.
Within that method all the logging comes back but the method does not
get called in the observer and I get false when I ask Is
SipNetworkPath alive? in the logging.
Is the observer class losing reference or something or is there a
mistake in my way of doing this? Does Android kill off objects that
are not part of an Activity or a Service instantly or something along
thoese lines that might be causing the problem?

[android-developers] How to create Multiple instances of an Activity From a Service?
I was wondering is it possible to create multiple instances of a
single Activity in Android?
I currently start my own inCall screen for a Voip Test by using the
following code: (Used in a Service)
---
public void initInCallScreen(String pName, String phoneNumber,
int contactID, boolean
callDirection, int lineID){
//starts in callScreen dialog
final Intent myIntent = new Intent(context,
CallDialogActivity.class);
myIntent.putExtra(NAME, pName);
myIntent.putExtra(NUMBER, phoneNumber);
myIntent.putExtra(ID, contactID);
myIntent.putExtra(CALLTYPE, callDirection); //True =
Incoming, False = Outgoing
myIntent.putExtra(LINEID, lineID);
myIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(myIntent);
---
This allows me to start the Activity fine.
However when I call it for a second it just returns to the Activity
already created rather than creating a new Activity and placing it on
the stack.
I would like to be able to create the activity multiple times so that
I have two or 3 Activities on the stack and the user can switch
between them, using Home, Back buttons etc...
Is this possible and if so what am I doing wrong?

[android-developers] How To Override the “Back” button so it doesn’t Finish() my Activity?
I currently have an Activity that when it gets displayed a
Notification will also get displayed in the Notification bar.
This is so that when the User presses home and the Activity gets
pushed to the background they can get back to the Activity via the
Notification.
The problem arises when a User presses the back button, my Activity
gets destroyed but the Notification remains as I want the user to be
able to press back but still be able to get to the Activity via the
Notification. But when a USER tries this I get Null Pointers as its
trying to start a new activity rather than bringing back the old one.
So essentially I want the Back button to act the exact same as the
Home button and here is how I have tried so far:
---
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (Integer.parseInt(android.os.Build.VERSION.SDK)
5
keyCode == KeyEvent.KEYCODE_BACK
event.getRepeatCount() == 0) {
Log.d(CDA, onKeyDown Called);
onBackPressed();
}
return super.onKeyDown(keyCode, event);
}
public void onBackPressed() {
Log.d(CDA, onBackPressed Called);
Intent setIntent = new Intent(Intent.ACTION_MAIN);
setIntent.addCategory(Intent.CATEGORY_HOME);
setIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(setIntent);
return;
}
---
However the above code still seems to allow my Activity to be
destroyed, How can I stop my Activity from being destroyed when the
back button is pressed?

[android-developers] How to save an object in onSaveInstanceState?
I have created a small XML parsing application for Android that
displays information in a listview and then allows a user to click on
the list view and a dialog with further info will pop up.
The problem is that when the screen orientation is changed when a
dialog screen is open I get a null pointer error.
The null pointer occurs on the following line:
---
if(setting.getAddForPublicUserNames() == 1){
---
This line is part of my dialogPrepare method:
---
@Override
public void onPrepareDialog(int id, Dialog dialog) {
switch(id) {
case (SETTINGS_DIALOG) :
afpunText = ;
if(setting.getAddForPublicUserNames() == 1){
afpunText = Yes;
}
else{
afpunText = No;
}
String Text = Login Settings: + \n
+ Password: + setting.getPassword() +
\n
+ Server: + setting.getServerAddress() +
\n
+ Register: +
setting.getRegistrarAddress() + \n
+ Realm: + setting.getRealm() + \n
+ Public UserNames: + afpunText + \n
+ Preference Settings: + \n
+ Request VDN: +
setting.getRequestVDN() + \n
+ Handover Settings: + \n
+ Enable Handover: +
setting.getEnableHandover() +
\n
+ Hand Over Number: +
setting.getHandoverNum() +
\n;
AlertDialog settingsDialog = (AlertDialog)dialog;
settingsDialog.setTitle(Auth ID: + setting.getUserName());
tv =
(TextView)settingsDialog.findViewById(R.id.detailsTextView);
if (tv != null)
tv.setText(Text);
break;
}
}
---
So the error is that my variable setting is null after the screen
orientation changes.
I have tried to use the onSaveInstance state methods to fix that as
follows:
---
@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
for(int i = 0; i settings.size(); i++){
savedInstanceState.putString(Username+i,
settings.get(i).getUserName());
savedInstanceState.putString(Password+i,
settings.get(i).getPassword());
savedInstanceState.putString(Server+i,
settings.get(i).getServerAddress());
savedInstanceState.putString(Registrar+i,
settings.get(i).getRegistrarAddress());
savedInstanceState.putString(Realm+i,
settings.get(i).getRealm());
savedInstanceState.putInt(PUserNames+i,
settings.get(i).getAddForPublicUserNames());
savedInstanceState.putString(RequestVDN+i,
settings.get(i).getRequestVDN());
savedInstanceState.putString(EnableHandOver+i,
settings.get(i).getEnableHandover());
savedInstanceState.putString(HandOverNum+i,
settings.get(i).getHandoverNum());
}
super.onSaveInstanceState(savedInstanceState);
}
---
and
---
@Override
public void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
//Check to see if this is required
// Restore UI state from the savedInstanceState.
// This bundle has also been passed to onCreate.
for(int i = 0; isettings.size(); i++){
settings.get(i).setUserName(savedInstanceState.getString(Username+i));
settings.get(i).setPassword(savedInstanceState.getString(Password+i)) ;
settings.get(i).setServerAddress(savedInstanceState.getString(Server+i));
settings.get(i).setRegistrarAddress(savedInstanceState.getString(Registrar+i));
settings.get(i).setRealm(savedInstanceState.getString(Realm+i));
settings.get(i).setAddForPublicUserNames(savedInstanceState.getInt(PUserNames+i));
settings.get(i).setRequestVDN(savedInstanceState.getString(RequestVDN+i));
settings.get(i).setEnableHandover(savedInstanceState.getString(EnableHandOver+i));
settings.get(i).setHandoverNum(savedInstanceState.getString(HandOverNum+i));
}
}
---
However the error still remains, I think I have to save the selected
setting from what was selected from the ListView? But how do I save a
setting object in onSavedInstance?

[android-developers] A clear, concise tutorial on PreferenceActivity Preferences?
I was wondering can anyone direct me to a detailed Preferences
tutorial?
Or provide me with a bit of help here?
I have my preferences saved in preferences.xml as follows:
PreferenceScreen xmlns:android=http://schemas.android.com/apk/res/
android
PreferenceCategory android:title=Wifi Settings
EditTextPreference
android:key=edittext_block_attach_err
android:title=@string/title_edittext_preference
android:summary=@string/summary_edittext_preference
android:dialogTitle=@string/
dialog_title_edittext_preference /
/PreferenceCategory
/PreferenceScreen
I then have a preference activity as follows:
public class WlanSettings extends PreferenceActivity {
SharedPreferences prefs;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preferences);
prefs = this.getSharedPreferences(CiceroWlanSettings,
Activity.MODE_PRIVATE);
}
This display's the EditTextPreference fine but how do I then set up a
default preference to be displayed in the dialog box that pops up with
an EditTextPreference?
And How do I save changes that occur in my preference activity to my
preferences?

[android-developers] Does Observer not work in a Android Service?
I am using the Observer pattern in my Android application to notify a
running service that some data has changed:
Here is the code outside the Service: (WifiConnectionManager)
---
//Observables
@Override
public void NotifyQCLevelChange(QCLevel newQoSLevel) {
setChanged();
notifyObservers( newQoSLevel );
}
@Override
public void NotifyQCPercentageChange(int percentage) {
setChanged();
notifyObservers( percentage );
}
---
Where the observables get updated within an Observer update method:
(WifiConnectionManager)
---
@Override
public void update(Observable arg0, Object arg) {
if( !iActive )
return;
if( arg0 instanceof WifiMonitor ){
Log.d(WifiConnectionManager, update from WiFiMonitor
ss=: +
arg.toString());
if( iConnectionState.equals(ConnectionState.IPACTIVE) )
{
int qcPercentage =
Integer.parseInt(arg.toString());
Log.d(GetActiveQCLevel, GetActiveQCLevel
called);
QCLevel aConnectionQCLevel =
GetActiveQCLevel(qcPercentage);
if(
!aConnectionQCLevel.equals(iConnectionQCLevel) )
{
iConnectionQCLevel = aConnectionQCLevel;
NotifyQCLevelChange(iConnectionQCLevel);
Log.d(NotifyQCLevelChange,
NotifyQCLevelChange);
}
NotifyQCPercentageChange(qcPercentage);
Log.d(NotifyQCPercentageChange,
NotifyQCPercentageChange);
}
}
---
And finally the Observer in my service: (WifiService)
---
@Override
public void update(Observable observable, Object data) {
if( observable instanceof WifiConnectionManager data
instanceof
QCLevel){
Log.d(WifiConnectionManager, instanceof QCLevel);
}
else if( observable instanceof WifiConnectionManager data
instanceof Integer){
Log.d(WifiConnectionManager, instanceof Integer);
}
else if( observable instanceof WifiConnectionManager){
Log.d(WifiConnectionManager, instanceof
WifiConnectionManager);
}
---
From the log I can see that Log.d(GetActiveQCLevel,
GetActiveQCLevel called);
Log.d(NotifyQCPercentageChange, NotifyQCPercentageChange); get
called but nothing in the update method of the Observer in my service
(WifiService) gets called.
Can anyone see where the problem is or is there a restriction I am not
aware of?

[android-developers] How to update a Widget dynamically (Not waiting 30 min for onUpdate to be called)?
I am currently learning about widgets in Android.
I want to create a WIFI widget that will display the SSID, the RSSI
(Signal) level.
But I also want to be able to send it data from a service I am running
that calculates the Quality of Sound over wifi.
Here is what I have after some reading and a quick tutorial:
---
public class WlanWidget extends AppWidgetProvider{
RemoteViews remoteViews;
AppWidgetManager appWidgetManager;
ComponentName thisWidget;
WifiManager wifiManager;
public void onUpdate(Context context, AppWidgetManager
appWidgetManager,
int[] appWidgetIds) {
Timer timer = new Timer();
timer.scheduleAtFixedRate(new WlanTimer(context,
appWidgetManager),
1, 1);
}
private class WlanTimer extends TimerTask{
RemoteViews remoteViews;
AppWidgetManager appWidgetManager;
ComponentName thisWidget;
public WlanTimer(Context context, AppWidgetManager appWidgetManager)
{
this.appWidgetManager = appWidgetManager;
remoteViews = new RemoteViews(context.getPackageName(),
R.layout.widget);
thisWidget = new ComponentName(context,
WlanWidget.class);
wifiManager =
(WifiManager)context.getSystemService(Context.WIFI_SERVICE);
}
@Override
public void run() {
remoteViews.setTextViewText(R.id.widget_textview,
wifiManager.getConnectionInfo().getSSID());
appWidgetManager.updateAppWidget(thisWidget,
remoteViews);
}
}
---
The above seems to work ok, it updates the SSID on the widget every 10
seconds.
However what is the most efficent way to get the information from my
service that will be already running to update periodically on my
widget?
Also is there a better approach to updating the the widget rather than
using a timer and timertask? (Avoid polling)

[android-developers] Get Notified when a new access point is added?
I was wondering is it possible to get a notification of when a new configured network is added to the WifiManager in Android? I know you can get the current list of configured networks http://developer.android.com/intl/de/reference/android/net/wifi/WifiManager.html#getConfiguredNetworks%28%29 But is it possible to get notification of when a new one is added? I dont see anything in the WifiManager that would be helpful. Has anyone any other ideas? Or insight into how this could be achieved? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Issue with WifiManager.calculateSignalLevel(RSSI, 5)
I am trying to use the Wifimanager to calculate the Signal Level of
the access points found during a scan.
I am using the following method:
http://developer.android.com/intl/de/reference/android/net/wifi/WifiManager.html#calculateSignalLevel%28int,%20int%29
But it appears to always return the same int no matter what the RSSI
level is.
Here is my code:
---
public int calculateQoS(int aRSSI){
signalLevel = WifiManager.calculateSignalLevel(RSSI, 5);
return signalLevel;
}
---
public void testCalculateQoS(){
Log.d(signal, signal = :
+ connMonitor.calculateQoS(-44)
+ + connMonitor.calculateQoS(-80)
+ + connMonitor.calculateQoS(-120)
+ + connMonitor.calculateQoS(-20));
}
The logging outputs 1 for all the test cases for calculateQoS(int).
Am I missing something simple here? Why is the SignalLevel always 1?

[android-developers] How to scan Access Points and select strongest signal?
I am currently trying to write a class in Android that will Scan for
access points, calculate which access point has the best signal and
then connect to that access point.
So the application will be able to scan on the move and attach to new
access points on the go.
I have the scanning and calculation of the best signal working.
But when it comes to attaching to the best access point I am having
trouble.
It appears that enableNetwork(netid, othersTrueFalse) is the only
method for attaching to an Access point but this causes problems as
from my Scan Results I am not able to get the id of the access point
with the strongest signal.
This is my code:
---
public void doWifiScan(){
scanTask = new TimerTask() {
public void run() {
handler.post(new Runnable() {
public void run() {
sResults = wifiManager.scan(getBaseContext());
if(sResults!=null)
Log.d(TIMER, sResults count + sResults.size());
ScanResult scan =
wifiManager.calculateBestAP(sResults);
wifiManager.addNewAccessPoint(scan);
}
});
}};
t.schedule(scanTask, 3000, 3);
}
---
public ScanResult calculateBestAP(ListScanResult sResults){
ScanResult bestSignal = null;
for (ScanResult result : sResults) {
if (bestSignal == null
|| WifiManager.compareSignalLevel(bestSignal.level,
result.level) 0)
bestSignal = result;
}
String message = String.format(%s networks found. %s is the
strongest. %s is the bsid,
sResults.size(), bestSignal.SSID, bestSignal.BSSID);
Log.d(sResult, message);
return bestSignal;
}
---
public void addNewAccessPoint(ScanResult scanResult){
WifiConfiguration wc = new WifiConfiguration();
wc.SSID = '\' + scanResult.SSID + '\';
//wc.preSharedKey = \password\;
wc.hiddenSSID = true;
wc.status = WifiConfiguration.Status.ENABLED;
wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
wc.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
int res = mainWifi.addNetwork(wc);
Log.d(WifiPreference, add Network returned + res );
boolean b = mainWifi.enableNetwork(res, false);
Log.d(WifiPreference, enableNetwork returned + b );
}
---
When I try to use addNewAccessPoint(ScanResult scanResult) it just
adds another AP to the list in the settings application with the same
name as the one with the best signal, so I end up with loads of
duplicates and not actually attaching to them.
Can anyone point me in the direction of a better solution?

[android-developers] A couple of Rom questions for the experts
I have a couple of questions for the Rom developers/experts on here regarding things that can be done with Android ROM's. Is a parser Rom upgrade possible? So is it possible to change a small part of a ROM and then allow users to upgrade their ROM easily? So can I change a part of a ROM and then a customer can upgrade to the newer ROM without having to be technically savvy and needing to root and flash their devices? Can a change be burnt into a ROM so that when a user selects Restore Factory Settings that it doesn't remove the upgrade to the ROM? So essentially I want to know if its possible (with a device manufacturers permission) to add to a ROM some small additional parts and then give this new ROM version as a firmware upgrade to the device so that a user only has to upgrade and not go through the process of rooting and flashing there device? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Some connectivity questions
I have a couple of questions about connectivity on Android, if anyone has any insight it would be great. What is the default when an application wants to wirelessly connect? Is it wlan? And if wlan is switched off or there is no access points around is it 3g or gprs? Is a device always ip connected? Or when its disabled from wlan or 3g does it's lose its ip address? Is an application, for example the browser only ever connected to one ip address? Or can it be connected to multiple addresses for each radio such as gprs or wifi (wlan)? Can an application decide which connection to open a socket to? For example can I create an application and decide whether to connect the socket to the wlan or gprs? Or does the OS decide? Finally how do native applications handle connectivity? In the same manner? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Querying the SMS ContentProvider?
I currently register a content observer on the following URI
content://sms/ to listen out for incoming and outgoing messages
being sent.
This seems to work ok and I have also tried deleting from the sms
database but I can only delete an entire thread from the following URI
content://sms/conversations/
Here is the code I use for that
Java:
String url = content://sms/;
Uri uri = Uri.parse(url);
getContentResolver().registerContentObserver(uri, true, new
MyContentObserver(handler));
}
class MyContentObserver extends ContentObserver {
public MyContentObserver(Handler handler) {
super(handler);
}
@Override public boolean deliverSelfNotifications() {
return false;
}
@Override public void onChange(boolean arg0) {
super.onChange(arg0);
Log.v(SMS, Notification on SMS observer);
Message msg = new Message();
msg.obj = xx;
handler.sendMessage(msg);
Uri uriSMSURI = Uri.parse(content://sms/);
Cursor cur = getContentResolver().query(uriSMSURI, null, null,
null, null);
cur.moveToNext();
String protocol =
cur.getString(cur.getColumnIndex(protocol));
if(protocol == null){
Log.d(SMS, SMS SEND);
int threadId =
cur.getInt(cur.getColumnIndex(thread_id));
Log.d(SMS, SMS SEND ID = + threadId);
Cursor c =
getContentResolver().query(Uri.parse(content://sms/outbox/ +
threadId), null, null,
null, null);
c.moveToNext();
int p = cur.getInt(cur.getColumnIndex(person));
Log.d(SMS, SMS SEND person= + p);
//getContentResolver().delete(Uri.parse(content://sms/
conversations/ + threadId), null, null);
}
else{
Log.d(SMS, SMS RECIEVE);
int threadIdIn =
cur.getInt(cur.getColumnIndex(thread_id));
getContentResolver().delete(Uri.parse(content://sms/
conversations/ + threadIdIn), null, null);
}
}
}
However I want to be able to get the recipricant and the message text
from the SMS Content Provider, can anyone tell me how to do this?
And also how to delete one message instead of an entire thread?

[android-developers] How to add my own Audio codec to AudioRecord?
I currently have a Loop back program for testing Audio on Android
devices.
It uses AudioRecord and AudioTrack to record PCM audio from the Mic
and play PCM audio out the earpiece.
Here is the code:
public class Record extends Thread
{
static final int bufferSize = 20;
final short[] buffer = new short[bufferSize];
short[] readBuffer = new short[bufferSize];
public void run() {
isRecording = true;
android.os.Process.setThreadPriority
(android.os.Process.THREAD_PRIORITY_URGENT_AUDIO);
int buffersize = AudioRecord.getMinBufferSize(11025,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT);
arec = new
AudioRecord(MediaRecorder.AudioSource.MIC,
11025,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT,
buffersize);
atrack = new
AudioTrack(AudioManager.STREAM_VOICE_CALL,
11025,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT,
buffersize,
AudioTrack.MODE_STREAM);
atrack.setPlaybackRate(11025);
byte[] buffer = new byte[buffersize];
arec.startRecording();
atrack.play();
while(isRecording) {
arec.read(buffer, 0, buffersize);
atrack.write(buffer, 0,
buffer.length);
}
}
}
So as you can see in the creation of the AudioTrack and AudioRecord
the Encoding is supplied via the AudioFormat but this only allows 16
bit or 8 bit PCM.
I have my own G711 Codec implementation now and I want to be able to
encode the audio from the Mic and decode it going into the EarPiece,
So I have encode(short lin[], int offset, byte enc[], int frames) and
decode(byte enc[], short lin[], int frames) methods but I'm unsure as
to how to use them to encode and the decode the audio from the
AudioRecord and AudioTrack.
Can anyone help me or point me in the right direction?

[android-developers] Supress the native In Call Screen and replace with 3rd party?
Currently creating a VOIP application for Android and I was wondering is there any possible way to supress the In Call Dialog when sending a call over GSM and use our own 3rd party In Call Dialog or screen instead? At the minute when we switch from our VOIP call and send it over GSM via the ACTION_CALL intent it does everything we want except it brings up the native In Call screen whereas we want our own In Call screen to display here. So I was wondering what kind of options we would have on this? What would you reccomend we look into doing?

[android-developers] intents getting incrementing each time received?
Hi all,
I have started using custom intents in my application and I have come
across a bit of a problem.
When I send a custom intent I register a Broadcast Receiver and I
catch the intent no problem.
However problems seem to appear when I send the intent again, the
Broadcast Reciever seems to register two events of the intent and so
on so if the intent is sent a third time I recieve it 3 times.
This is causing major problems in my application and was wondering is
it normal and there is some way I have to deal with it?
Here is my code:
To Send the Intent:
Intent i = new Intent();
i.setAction(SIP_INCOMING_CALL_CANCEL_INTENT);
sendBroadcast(i);
To receive the Intent:
sipIncomingListener = new BroadcastReceiver(){
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if(CallDialogActivity.SIP_INCOMING_CALL_ANSWER_INTENT.equals(action)){
Log.d(SIPENGINE, CALL CONNECTED SENT FROM INITINCOMINGLISTENER());
}
};
IntentFilter filter = new
IntentFilter(CallDialogActivity.SIP_INCOMING_CALL_CANCEL_INTENT);
registerReceiver(sipIncomingListener, filter);
Is there anyway to make sure the Intent is only fired once??

[android-developers] Ringtone.stop() wont work?
I currently start a Ringtone on Android and it plays fine.
However when I try to stop the ringtone it doesn't stop or atleast
doesn't stop straight away, it will keep in playing until it just
plays out.
Here is how I set up the Ringtone:
int rm = audio_service.getRingerMode();
int vs =
audio_service.getVibrateSetting(AudioManager.VIBRATE_TYPE_RINGER);
android.os.Vibrator v = (Vibrator)
getSystemService(Context.VIBRATOR_SERVICE);
if ((rm == AudioManager.RINGER_MODE_VIBRATE ||
(rm == AudioManager.RINGER_MODE_NORMAL vs ==
AudioManager.VIBRATE_SETTING_ON)))
v.vibrate(vibratePattern,1);
if (audio_service.getStreamVolume(AudioManager.STREAM_RING) 0)
{
oRingtone = RingtoneManager.getRingtone(this,
Settings.System.DEFAULT_RINGTONE_URI);
oRingtone.setStreamType(AudioManager.STREAM_RING);
oRingtone.play();
}
And here is how I try to stop it
if (CallDialogActivity.oRingtone != null) {
Log.d(RINGTONE, Into Ringtone if);
Ringtone ringtone = CallDialogActivity.oRingtone;
oRingtone = null;
ringtone.stop();
}
Has anyone come across similiar problems or see any mistakes in my
code?

[android-developers] Android - minimal UI, services or broadcast recievers?
I have an application that will have no User Interface (not exactly none altogether but VERY minimal). I want it to scan for Wifi access points at regular intervals, check the connected state of Wifi and check the connected level of the currently connected access point. It also listens for the OUT_GOING_CALL broadcast and traps the call if connected to wifi and then pops up a dialog that tells the user the call has been blocked and offers the user cheaper options than Gsm if there are any. I currently use the Broadcasts to get the Scan Results and to get changes in the connected Level of the wifi connection also. However I had thought that moving these to a service of my own would be a good idea, however would I be better leaving them as Broadcast Recievers in Non Activtiy and Non Service classes and just make the main Engine of the application a service that turns on and off these broadcasts from there Classes (Objects) ? So I was wondering would having several services, one that does the wifi stuff, one that does the call monitoring, and one that drives the whole thing? Or would I be better off using BroadcastRecievers to listen out for changes instead and implement a timertask to scan for access points and only have one service being the engine that drives it all? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Loop audio from mic to earpiece?
Hi Micheal,
do you fancy helping me try to solve the ear piece problem to make it
two pints? :-)
It initially sounds like it gets routed to the ear piece on the HTC
Hero but thats because of the way the earpiece and speaker are set up
on the hero, on a G1 it is clearly coming through the speaker.
here is the full code I have:
boolean isRecording; //currently not used
AudioManager am;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
am = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
Record record = new Record();
record.run();
}
public class Record extends Thread
{
static final int bufferSize = 20;
final short[] buffer = new short[bufferSize];
short[] readBuffer = new short[bufferSize];
public void run() {
isRecording = true;
android.os.Process.setThreadPriority
(android.os.Process.THREAD_PRIORITY_URGENT_AUDIO);
int buffersize = AudioRecord.getMinBufferSize(11025,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT);
AudioRecord arec = new AudioRecord
(MediaRecorder.AudioSource.MIC,
11025,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT,
buffersize);
AudioTrack atrack = new AudioTrack
(AudioManager.STREAM_VOICE_CALL,
11025,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT,
buffersize,
AudioTrack.MODE_STREAM);
am.setRouting(AudioManager.MODE_NORMAL,
AudioManager.ROUTE_EARPIECE,
AudioManager.ROUTE_ALL);
Log.d(SPEAKERPHONE, Is speakerphone
on? : + am.isSpeakerphoneOn());
atrack.setPlaybackRate(11025);
byte[] buffer = new byte[buffersize];
arec.startRecording();
atrack.play();
while(isRecording) {
arec.read(buffer, 0,
buffersize);
atrack.write(buffer, 0,
buffer.length);
}
arec.stop();
atrack.stop();
isRecording = false;
}
}
}
The log message shows that isSpeakerPhoneOn returns false yet the
audio still comes through the speaker,
The setRouting method is deprecated and doesnt work either and no
matter what stream I choose in the AudioTrack
constructor the audio gets played out over the Speaker.
Cant find much on it with a search either, just people having the same
problems as me.
Would you or anyone have any insight on how to get it to play through
the ear piece?
Thanks again in advance,
Donal

[android-developers] Loop audio from mic to earpiece?
Hi all, I was wondering is it possible with Android to record from the mic and play the sound back out the earpiece with just a 1 second delay? I have seen the tutorials and can currently record from the mike and save a 3gp file to the sd card. However is it posssible to record and say stream the audio straight to the ear piece with just a 1 - 2 second delay? If so how would I go about doing this? Would I need to record from the mic and save it to a file and then repaly to the ear piece? and continually do this? Or would it be possible to record from the mic and stream it directly to the ear piece with just a slight delay? Any help, info or directions to tutorials would be greatly appreciated, Thanks in advance -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Loop audio from mic to earpiece?
Hi Mike, Thanks for the prompt reply. I was looking at the AudioRecord class but had somehow missed the AudioTrack class, thanks for pointing it out. From looking at the classes I think what I have to do is read the recording data and put it straight into a streamed AudioTrack, would I be correct in saying that? And then is it possible to send it to the earpiece? Thanks again, Donal On Jan 21, 11:36 am, Michael nicholls...@googlemail.com wrote: AudioRecord and AudioTrack are the classes you need. If you use them in streaming mode then you can pipe data out of AudioRecord straight into AudioTrack and you should be able to acheive the desired effect. I have done something similar, but without the delay.

[android-developers] Re: Loop audio from mic to earpiece?
Hi Micheal, Thanks again, I now have it recording in PCM format from the mic and saving it to the sd card and then playing it back through the ear piece. So I just have to look into how to into piping the AudioRecord straight into the AuditTrack. So with the AudioRecord instead of creating a file to save to what should I look into doing? And with the AudioTrack, instead of looking for a file to read in what should I look into doing? Thanks, Kind Regards, Donal On Jan 21, 1:10 pm, Michael nicholls...@googlemail.com wrote: Hi Donal, Yeah if you kick the record off and the play, then you can sit in a loop reading the data out of Record and putting it into play (on a thread other than the UI thread of course). Not 100% sure about the earpiece, but you specify a stream when you create the AudioTrack and I think a stream encpsulates audio routing and volume amongst possibly other things. If you set the stream to STREAM_VOICE_CALL it might come through the earpiece as this is where a call would be routed, although I guess that depends on headsets and stuff. Can anyone clarify if I am right? Mike On Jan 21, 11:49 am, draf...@gmail.com draf...@gmail.com wrote: Hi Mike, Thanks for the prompt reply.

[android-developers] Cant get data from my service
I have a service that is running fine and I can see the data
collecting in the logcat,
However after creating an aidl and trying to get the information from

I just cant seem to get the data to pass across at all, I always get a

Here is my service class, I want to get the connectedLevel int to use

[android-developers] Re: READ_SMS permissions not working
Hi Moneytoo,
Is there a way to monitor changes in the outbox through an official
API?
I need to be able to listen out for an sms message beinging sent and
be able to deal with that through my own application.
However I have been researching the official API and I cant find
anything that will let me do this?
Is there some way of doing it with the official API that I have
missed?
Thanks in advance

[android-developers] Call Log Questions
Hi all, I have been trying to Query, insert and update the Call Log for the past few days. Query is fine, have no problem with that. But I'm wondering does the content provider allow you to add a new event to the call log or update events already on the call log? I see there is no CallLog.Calls.CONTENT_DIRECTORY option for adding new data like there is with the Contacts content provider. I have also tried updating an event already on the call log but this has left errors in the program, the calls queried dont display and when I go to the Call Log screen it crashes. Here is the code ContentValues values = new ContentValues(); values.put(CallLog.Calls.CACHED_NAME, TestCase1); Uri uri = ContentUris.withAppendedId(CallLog.Calls.CONTENT_URI, 1); int rows = getContentResolver().update(uri, values, null, null); Log.d(DEBUG, Rows Updated: + rows); I get an uncaught handler and null pointer exception error Is my problem that its not possible to add or update to the call log content provider or should it be possbile?
