Is there a way to change Sms Limit from android studio?

I am creating an app for a person I know for his company, he needs to send many SMS to his workers(shifts mostly). He asked me to create this app but now after I almost fished it I found out that there an SMS limit, is there a way to change it from the app with permissions or something and not make him dig through his root? Or at least make the annoying message pop up just once and not for every message that sends after the limit reached?

you have to use abd command to open that restrictions here is the link for tutorial
change sms limit
Go to the android platform tool directory
(C:\Users\username\AppData\Local\Android\Sdk\platform-tools)
open command shell by using Shift+mouserightclick
and enter this command
adb shell
settings put global sms_outgoing_check_max_count 5
settings put global sms_outgoing_check_interval_ms 9000000
I am actually reducing the number so Android warns me if I have sent more than 5 SMS messages within 30(9000000) minutes. Change “5” to whatever number you wan

is there a way to change it from the app with permissions or something
No, sorry.
Or at least make the annoying message pop up just once and not for every message that sends after the limit reached?
No, sorry.
If you wish to send bulk text messages, use a hosted SMS delivery service, such as Twilio.

android send Dial Tone and detect end of input

I'm developing a little app which needs to start a simple call and send some DTMF tones.
By searching on the net i found that the correct way for doing it should be the following:
Intent i = new Intent("android.intent.action.CALL",
Uri.parse("tel://" + number + "," + dtmfTones));
Now, my problems are 2:
I need to shut down the call after tones are sent.
If possible I would like not to open the default dialer.
My app only needs to perform the call and send the tones, so the user has nothing to do nor interact with and that's why I don't need to open the dialer, it can also be done in background. Is there a way to do those things?
Thanks all and sorry for my not perfect english.
EDIT1: I tryed this method and I performed a call to another mobile number I have under control. The tones are sent and you can listen them without any problem.
EDIT2: i found also some apps which uses an unusual sequence of "#", ",", ".". but it is still not working, any idea?
I tryed to perform the same call to the house number which has to reply (it's a security system) but it doesn't recognize them. I don't know what I'm missing.

Start Android application from NFC-tag with extra data

I can start my application by simply putting the phone on a NFC-tag. But I would like to take the idea one step further. Imagine a simple time-tracking application with two NFC-tags. The first will start (and download) the application and register a starttime. The other will also start (and download) the application, but register a stoptime.
My problem I'd like to solve is that I don't want my phone to know about these tags. The application should not need to have a list of tag-ids programmed and know what actions that is connected to each id. The tag should carry the information needed to start the action on the phone with the correct parameters.
Are there any information about how to accomplish this scenario? I have installed "nfc-eclipse-plugin" but doesn't understand how to use it to get my goal and even less how to get my application to read the extra data.
Thanks in advance

Your tags should be capable of storing NDEF messages. Such messages are automatically read out by Android and passed to your app in an Intent. Automatically installing and/or starting your app can be accomplished by putting an Android Application Record in your tag. Any additional information ("start" or "stop" indication) can be stored in a proprietary record.
You probably want to put the AAR as the last record of the NDEF message, as it is detected and acted upon by Android automatically, but is only supported since ICS. To make automatic installation work with Gingerbread, you can put an additional URI record or SmartPoster record with a Google Play Store link in it as the first record of the message. Your app should then filter (ACTION_NDEF_DISCOVERED) for this URI, so it will also start automatically on Gingerbread.

Android & iOS access number dialing

I am very new to both these operating systems so please excuse me if my question is basic :-)
We are planning a secure dialing system which means dialiing 2 numbers in one phone number dailing session.
Currently we have a system which allows us to dail an access number, wait for a tone and then dial a full telephone number.
It's a bit elaborate but like I said, it's a security feature.
What we are now trying to do is create Android and iPhone apps that will allow us to dial the access number + telephone number at the click of a virtual button :-)
Can anyone tell me how this can be accomplished programmatically? I need to implement something like access-number#phone-number or anything that works.
Thanks.

Both iphone and android support making phone calls in the same sort of manner.
You need to construct a URL and 'run' the url. Both iphone and android don't support any sort of call control so you have to make do with the url to make a phone call. They both support 'pause' character and dtmf tones in the url.
The iphone don't support some characters, notably the '#' and '*' characters. Because the '#' character is not supported (for security reasons), it can make it hard dealing with PBX systems.
On the android you have to 'encode' characters manually or using URLEncoder. I have not had any luck supporting the '#' character in Android but I have seen reports of it working. You will need to test this to see if it works for you.
For iphone you use the UIApplication openURL: to a tel link.
e.g.
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:#"tel:123456p12345"]];
For android you use the INTENT_DIAL or ACTION_CALL.
INTENT_CALL will display the phone dialler with you number filled out. It does not require any special setup.
e.g.
Intent dialIntent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:123456"));
startActivity(dialIntent);
ACTION_CALL requires the CALL_PHONE permission in your manifest file.
e.g.
AndroidManifest.xml:
Intent dialIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:123456%2C12345"));
startActivity(dialIntent);

I'm not quite sure if this is what you're looking for but.
You could create a button in your layout.
Create a pointer to it in your main activity // findViewById();
OnClickListener on the Button.
in the onClick, fire a Dial Intent with the number of choice.
If this isn't what you're looking for I'm afraid I'll need a bit more information on what it truely is, because at this point that's the only thing I can manage to think of with the description given.

android how to get the emergency number to call

I see there are plenty of examples on how to call a number, and I also see that I can only have it pop up the dialer to go to an emergency number. But in all those example they hard coded "911" as the number to use. well this works fine in the US but since android phones are sold in other countries and thusly there is the possibility that my app will be bought by someone not in the US, or that someone who lives in the us may take their phone overseas; is there a way then my app can realize it's not in the us and thusly has to use a different number to call emergency service and what that number would be?
So to sum up I'd like to know if there is a way I can have it so when the app goes to bring up the dialer with the emergency number for the country it's in, with out having to know that number at complie time?

According to the source for PhoneNumberUtils.isEmergencyNumber():
String numbers = SystemProperties.get("ril.ecclist");
if (TextUtils.isEmpty(numbers)) {
// then read-only ecclist property since old RIL only uses this
numbers = SystemProperties.get("ro.ril.ecclist");
}
numbers will be a comma separated list.
