Android :: Telephony Manager Functions Don't Work / What To Do?
May 29, 2009
I have low expectations that this message will get any response as it seems that Google developers do not like to address issues too close to the Android core and to strategic mobility applications. However, as they say, hope is the last to die.
I am really puzzled by the lack of response to queries about issues with some TelephonyManager functions.
Specifically, there have been a number of requests in the past, including mine, about
getNeighboringCellInfo()
As per the link below, getNeighboringCellInfo() is a documented TelephonyManager function available to application developers.
http://developer.android.com/reference/android/telephony/TelephonyMan...()
Yet, getNeighboringCellInfo() does not work. Any attempt to call it in an application results in application failure.
What is the problem here? If Google does not want application developers to use this function (I cannot fathom why that would be the case), then please remove it from TelephonyManager, and save all of us time and frustration.
It's really puzzling that for such an open platform Android has so many secrets and rules.

I would like to know what are the main differences between TelephonyManager and PhoneStateListener, because you can do (more or less) the same things with both. For example, you could create an incoming calls register implementing a broadcastreceiver and using TelephonyManger API or extending PhoneStateListener class and registering this new listener throughTelephonyManager . Case 1 - BroadcastReceiver (TelephonyManager)

Is there a way to look up the user phone number other than TelephonyManager? In my G1, this returns null: // get your phone number TelephonyManager telephonyManager = (TelephonyManager) getSystem Service (Context. TELEPHONY_SERVICE); String tel = telephonyManager.getLine1Number(); Log.i("Telephone Number ==> ", tel+" <=="); Is there any other way of getting user's own phone number? take care, Muthu Ramadoss. http://linkedin.com /in/tellibitz http://androidrocks.googlecode.com - Android Consulting.

I am not getting call in number in off_hook state when it is only coming in dialing state. According to documentation it should provide call in number for off_hook state as well. Is it a bug?

I have a European GNex (4.3) that is not tied to a carrier. I also have a Nexus 10 on 4.3. On both devices, I have activated "Allow remote lock and factory reset" in the Google Settings app.However, while I have all functionalities shown as activated on the ADM web interface for the Nexus 10, my GNex is "stuck" with only the "Ring" function active. I have unchecked and rechecked "Allow remote lock and factory reset" and refreshed the web page, deleted the data from the Google Play Services app and rebooted, tried combinations of all of these, all to no avail. The ADM web interface continues to show only the "Ring" function for my GNex, with "Lock" and "Erase" greyed out.

I have an HTC Evo with 2.2 on it.
I installed the usb drivers and ran Unrevoked on it last night. Unrevoked ran ok on it and said 'Done' at the end. When I hold the volume down and power button, the top of the screen says: "SUPERSONIC EVT2-3 SHIP S-OFF".
Since it shows "S-OFF" and unrevoked seemed to run successfully, I think I'm rooted, but I'm not really sure. I have the Superuser icon in my programs list, and I am able to run a 'root only' screenshot program.
So here's the problem. The reason I tried to root is to delete some of the bloatware from Sprint and for wireless tethering. I tried running Titanium Backup and got the following error: "Error: Sorry, I could not acquire root privileges. This application will not work! Please verify that your ROM is rooted and try again".
Wireless tethering will run and I can connect to it with my laptop, but after I'm connected, I can't access any web pages. Have I downloaded the wrong wireless tethering program? (I downloaded the latest one listed at this page: wireless_tether_2_0_5-pre9.apk - android-wifi-tether - Wireless Tether for Root Users 2.0.5-pre9 *** EXPERIMENTAL *** - Project Hosting on Google Code).
So, am I rooted or not? Am I "partially" rooted, since the screenshot program will run? What do I need to do to get the wireless tethering to work?

I have a count down timer that when it goes off (to zero) it checks to see if the app has focus. If not it launches a notification in the notification bar. When you click on the notification is re-opens the app. Now all of this works fine but if the screen happens to go off, the timer keeps going and the notification is available at the right time but never actually vibrates or rings until i turn the screen back on. Then it displays the notification like it was waiting in a queue or something.
How do I get it so that the notification manager will actually alert the user when the screen is turned off?
Update: If I set the timer for 2 minutes, it takes another 2-3 minutes for the notification to actually work. So it does work but it's on a huge delay! Code: So I setup the notification service when the app loses focus, and when the MyCount1 is finished is checks if the app has focus and if not it shows the notification. This all works when the screen backlight is on. Once it goes off it is unreliable.
@Override
public void onWindowFocusChanged(boolean hasFocus){
if(hasFocus == false){
mFocusFlag = false;
ns = Context.NOTIFICATION_SERVICE;
mNotificationManager = (NotificationManager) getSystemService(ns);
icon = R.drawable.statusbar;
tickerText = "Check the timer!!!";......................................

So I followed droid-life.com instructions on rooting and installing Froyo FRF57. I'm currently running Froyo but thought it would be nice to upgrade my ROM to Jrummy Kangerade 1.0. So I paid for the premium Rom Manager and have tried doing the backup Rom feature. It reboots my phone and does nothing. No backups appear in Rom manager.
Okay, so I said forget it. I'll just install the ROM. So it goes through the whole process and says it needs to reboot and then nothing happens. It doesn't reboot at all. I try manually rebooting and it doesn't do anything. Is there a trick to make this software start working?

I know similar topics regarding ClockworkMod/ROM Manager have been discussed, but I'm having a new issue and can't seem to find any info about it. Here's my issue: My backups don't work. When I try to flash one I'm being told there is an "MD5 mismatch." This happens when I try to restore any of my backups - including one I just made about an hour ago. I'm in the middle of flashing the newest Liquid Frozen Yogurt ROM and I goofed while restoring some things. I wanted to go back to v1.71 and start over, but I'm getting that error message. Perhaps not coincidentally, I have been unable to make any backups straight from ROM Manager. Nothing would happen. It isn't like the issues many of us have had in the past where it would appear to be booting into recovery and then just reboot. This time nothing happens at all. So my most recent backup was made by manually booting into recovery and going from there. I'm a little concerned. Any thoughts?
When I was having the issue using ROM Manager to make backups, I tried the old trick of flashing SPRecovery and then re-flashing ClockworkMod. Still didn't do anything.

Did a quick search and didn't see anything- Running "Fix Permissions" in rom manager results in "An error occurred while attempting to run privileged commands"
Reinstalled busybox via titanium backup, didn't fix.

I have researched extensively and am pretty sure this is not possible. I want to make a call and then inject DTMF when the far end answers. So 2 questions Is it possible ?
If not, how do I work to get it on the list of upcoming features to be provided on Android. I can say that this is possible on BlackBerry and Symbian, so Android is falling behind in this regard.

There are a number of network types defined in TelephonyManager:
NETWORK_TYPE_GPRS
NETWORK_TYPE_EDGE
NETWORK_TYPE_UMTS
NETWORK_TYPE_CDMA
NETWORK_TYPE_EVDO_0
NETWORK_TYPE_EVDO_A
NETWORK_TYPE_1xRTT
NETWORK_TYPE_HSDPA
NETWORK_TYPE_HSUPA
NETWORK_TYPE_HSPA
Is there any info out there that describes what range of speeds you can expect on each of these? If that isn't available, it would be nice to be able to order them based on speed.

I was wondering if there is a way to manipulate the emulator to simulate telephony signal strength changes.
I would like to test code that uses TelephonyManager.listen() with LISTEN_SIGNAL_STRENGTHS.

TelephonyManager.getNetworkType() returns one of the constant values.It appears that the constant values have an integer order, by possible bearer link speed.I know using constant values used in the following manner is generally bad,however could one use this to determine a basic cutoff for application functionality and have it work between API levels? (in API-v1 there was nothing above 0x03)if( telephonyManager.getNetworkType() > TelephonyManager.NETWORK_TYPE_EDGE ) return "3G! party on!";else if( telephonyManager.getNetworkType() > TelephonyManager.NETWORK_TYPE_UNKNOWN )}

I have looked all over the place. Here in the forums, online, user manuals, etc. What I am looking for: When I am texting, I see above the "A" key is an alt symbol that looks like an arrow pointing to the right with a verticle line. It appears to be an ALT-function of some sort. What is it? What does it do?

I read in the documentation for SQLite that there should be some core functions and aggregate functions available, but I can't seem to use them in my code.. Can anyone help? Here's the documentation ad: http://www.sqlite.org/lang_aggfunc.html http://www.sqlite.org/lang_corefunc.html There is for example the function count() but how do I use it? I have tried to use it as stated below, but none of the functions in the documentation is available that way (i.e when I type "db." the list that shows in Eclipse documentation doesn't include any of the functions from the SQLite doc except from execSQL):
