I have an application that creates a notification with sound when a specific text comes in. To do this, I detect the current ringerMode, change the ringerMode to normal, play the sound, and then quickly return the ringer back to its original setting.

I've posted this on Android Security as well, but that group does not appear to have as much activity. Actually I guess my question belongs in this group anyway, even though it touches on some of the security aspects of android packages. My goal is to access the certificate that was used to sign the apk package; and ordinarily, I would do that from inside the program like this
Certificates[] signingCertificates = getClass().getProtectionDomain().getCodeSource().getCertificates();
Unfortunately it appears that getProtectionDomain() returns null on android - according to the specs
http://developer.android.com/reference/java/lang/Class.html#getProtec...
This method might return null (to converse space?) but only for system classes. Since I'm calling this from one of my own classes, I would expect to get a non-null value, but unfortunately not. I have tried from the emulator, and from an application deployed on my phone using adb through a USB cable. I'm using the latest SDK (2.2) and targeting android 1.6. So I guess I have two questions, the first being: why does getProtectionDomain return null, and have anyone had any success using this method from inside an android application. And the second: Is there some other way to access the certificate that a given apk package was signed with (I can live with the restriction that only a given package can know its own certificate).
I have a click listener:
private OnClickListener onMyListener = new OnClickListener() {
public void onClick(View v) {
myMethod();
} };
And my Method:
private String myMethod() {
TextView tv = (TextView) findViewById(R.id.TextView1);
return (String) tv.getText();
}
When it calls this method, at tv.getText() it breaks in the debugger.

Kids, while they are at school, wish to have the phone in silent mode. All other time, would like to have the ringer on. Is it possible to program the ringer mode with days and time? Is it a challenge to Android or the device manufacturers or for Google? Anyway, my kids will be the first users, if it is available.
View 4 Replies View RelatedI have the following broadcast receiver:
public class MyRingModeReceiver extends BroadcastReceiver {
@Override public void onReceive(Context context, Intent intent) {
Logger.iLog("In my Receiver"); } }
I then have a service that onCreate does the following:
IntentFilter filter = new IntentFilter();
filter.addAction("android.media.RINGER_MODE_CHANGED");
registerReceiver(new MyRingModeReceiver() , filter);
When I place a call to the emulator and use the volume keys to modify (silence) the ringer
nothing happens.
I'm building an Android application that needs to communicate with a MySQL database. The application isn't meant to be published, and I want the application to be the only thing allowed to interface with the web service I'll create for DB access.
I've been thinking how I can secure the system, and this is the idea I've come up with. I'd appreciate any feedback or other ideas. Surely there is a method built into Android that I am unaware of.
My thought is to give the web service a GUID. Each time a call is made to one of it's public methods, the web service matches its GUID with the GUID given to it by the Android application. If the GUIDs do not match, the web service refuses access. In short, my system has a 128-bit password.

Back when I had my LG Envy, I could set it to rign and vibrate at the same time, cause at time I am in a load area and cannot hear the ring. Can I set my Ally to Ring and Vib at the same time?
View 3 Replies View RelatedI've got some problems muting the phone via code. The app I develop should mute the phone when a call comes in. This means it should not ring and vibrate at all. My first attempt so archive this was setting the AudioManager Ringer Mode to RINGER_MODE_SILENT using the following code.
AudioManager am = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE); am.setRingerMode(AudioManager.RINGER_MODE_SILENT);
While the phone stops ringing it continues to vibrate although the documentation of RINGER_MODE_SILENT says it should also stop vibrating. My second attempt was to switch off the vibration mode manually. am.setVibrateSetting(AudioManager.VIBRATE_TYPE_RINGER, AudioManager.VIBRATE_SETTING_OFF ); But this also doesn't stop the phone vibrating.
I use Ear to set my ringer profile and it seems to work great. However the ringer volume often goes to silent mode, because I unintentional push the ringer volume button and I miss the calls. Does anyone have a solution for this? Is it possible to turn of the ringer volume button on the Hero?

View 5 Replies View RelatedI have an activity A which uses SharedPreferences to share data with a service S, which is called from within A.Now when I call the stopService() method from A, the onDestroy() method in S is not called immediately.I thought that all the activities and services under a single apk run in just one process. Why then does the jump to onDestroy() not take place immediately instead I can see the output from onDestroy() after the further code in the activity A is executed.

View 7 Replies View RelatedI'm trying to change the ringer mode of the phone to RINGER_MODE_SILENT when a call is incoming by using the following lines of code.
CODE:...............
While the phone stops ringing it continue to vibrate although the documentation of RINGER_MODE_SILENT says it should also stop vibrating.
I'm using the SDK 1.6
UPDATE:
As I didn't find a solution yet, I tried to deactivate the vibration settings manually.
am.setVibrateSetting(AudioManager.VIBRATE_TYPE_RINGER, AudioManager.VIBRATE_SETTING_OFF );
But this also doesn't prevent the phone form vibrating when a call is incoming.
UPDATE 2:
Today I tried to solve the problem by canceling the vibration via a Vibration object.
Vibrator vib = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
vib.cancel();
Again, without success. Now I'm running out of ideas and asking myself if it is possible to stop the vibration at all.
UPDATE 3:
I've discovered another interesting fact when I've reread the documentation of the Vibrator class. The documentation says:
"If your process exits, any vibration
you started with will stop."

I am trying to execute a {public void} method in Service, from scheduled TimerTask which is periodically executing.This TimerTask periodically checks a condition. If it's true, it calls method via {className}.{methodName};However, as Java requires, the method needs to be {pubic static} method, if I want to use {className} with {.dot}.The problem is this method is for notification using Toast(Android pop-up notification) and Status Bar.But for this to work, the method must not have {static} modifier and resides in Service class.So, basically, I want background Service to evaluate condition from scheduled TimerTask, and execute a method in Service class.Can anyone help me what's the right way to use Service, invoking a method when certain condition is satisfied while looping evaluation?

View 16 Replies View RelatedLast week I was in the US and had gotten the AT&T pay-as-you-go sim. It charges 1c/kb and I thought that's not too bad since I *only* get outlook and yahoo email. Well, *before* I knew it, it sucked up $14.40 for internet access....Frantically called AT&T customer service and after a long wait, they told me that my device had access the service and downloaded 1.5Mb! I asked them if there was a way to turn off the GPRS(since I was mostly interested in their $2/day unlimited calling service) and they said they don't have a way to turn it off Tried a bunch of things like turning off auto-sync (in settings) etc...but STILL I ended up paying $40 by the end of the day!!
Is their a way to turn off GPRS completely and also monitor what applications are accessing the service? All I have to go by is what AT&T says at the website!
I have loaded some of my own music to use as ringers, and they show up when selecting phone ringers and via contacts to select unique ringers for specific contacts, but they do NOT show up when I am trying to select the ringer to use for SMS messaging. Only the factory ringers show up for SMS. Any idea how to get my side loaded music to work as the SMS ringer?! I can't stand the factory ringers. This was so easy to do on my BB Curve and Palm Pixi, so I am baffled why I can't figure it out on my Moment.

View 2 Replies View RelatedI've been a couple of days trying to solve this thing but I can'f figure it out.The problem is, simple activity, with simple layout, ScrollView -> LinearLayout -> and a lot of buttons inside the layout (within the scroll content). Everything works just fine but one tricky thing. When I click a button let's say at the top of the scroll content and inmediatelly I scroll down to the bottom of the content and I click other button there, nothing happens until I click a second time and all come to normal again.This can be reproduced anytime and it's code independent (i've tried more than 20 scenarios). I've not much experience in android yet but looks like the scroll listener stops the onclick listener or something like that.

View 4 Replies View RelatedI'm trying to log the phone's cell movement. So I created a PhoneStateListener that is being called when the CellLocation has been changed. Then it informs a logging service to write that new cell information to a log file.
This works as long as the screen is on. But when the screen goes off, the logging stops.
I have two classes:
The PhoneStateListener gets loaded on boot time public class CellStateListener extends PhoneStateListener { public void onCellLocationChanged(CellLocation location) {...this is the logging service which is informed when the cell location changes listener.onCellChanged(mcc, mnc, lac, cid); ... }
So I've been extremely frustrated by this for a long time now.I've posted before, but can't seem to find a good solution. My goal is to have something pretty much exactly like the installed application details page in the Android Market.I need a list of items displayed along with other content above the list, and would like the content above to scroll up along with the list (exactly like the application details does for the "My Review" and other descriptive info).Due to responses to my previous posts, I came to believe that it really wasn't possible to do this with a ListView.So rather than using a ListView, I refactored my code to use a simple LinearLayout and add individual View items to the list, thinking I could just set each View as clickable and add an OnClickListener to each View in the LinearLayout.That's not working at all though, and now I'm getting even more frustrated.If someone can help me get the OnClickListener working, then I think it'll work, but I do need a separator for the LinearLayout.How do I add a separator like the one used for ListView to my LinearLayout?
View 12 Replies View RelatedMy app which was working on 2.1 and earlier version fails to run properly in 2.2. It relies on the location but I do not get any error message. However under DDMS /logCat, I see a message saying: Error message while getting the location address: Reason: this service is not available. This is coming more as an information message rather than an exception or error. The process that is printing it out is System.out. Note that I did everything possible ( I can think of) to upgrade the app to run in android 2.2. The API version was changed to 8.
The manifest file contains all the following:-
<uses-library android:name=*"com.google.android.maps"*/>
</application> <uses-sdk android:minSdkVersion=*"8"* />
<uses-permission android:name=*"android.permission.INTERNET"*/>
<uses-permission android:name=*"android.permission.ACCESS_FINE_LOCATION"* />
<uses-permission android:name=*"android.permission.ACCESS_COARSE_LOCATION"* />
I have an Android Service that is started by my application and does some things in a threadPool using Executors.newCachedThreadPool()
Once it has finished doing it's work I would like the service to stopSelf(), how can I get the service to determine when it is no longer needed (ie, there are no more Threads executing) so that it can shut itself down automatically?
This is the scenario:
1 user has a main activity used for ii.
2 program needs to communicate with peers and keep connection and wait for messages
3 when a message comes it is shown in the main activity. so the question is should I use a service for the communication and what type of service? and also should I use Aspects in the service in order to keep my ii responsive and why?
