Can i get some help please
Thank you
Check your Error :
The method sendTextMessage(String, String, String, PendingIntent, PendingIntent) in the type SmsManager is not applicable for the arguments (EditText, null, String, null, null)
The first argument doesn't match, you are passing an EditText instead of a String.
I suggest you change as following:
smsManager.sendTextMessage(txtphoneNo.getText().toString(), null, Text, null, null);
The error is quite clear:
The method is:
sendTextMessage(String, String, String, PendingIntent, PendingIntent)
but you call it with the arguments (EditText, null, String, null, null)
Notice how the first argument is a EditText and not a String (which it wants)
You should use txtphoneNo.getText().toString()
EditText is not a string. Change your call to this:
smsManager.sendTextMessage(txtphoneNo.getText().toString(), null, Text, null, null);

So, in this code, my intention is to save a list of Points in an ArrayList of Points that will be use later. But all the points (latitude and longitude) have the same value, once i have the first value, all the others values are the same, its seems like onLocationChanged is never called.
Can someone help me?
You have a global point p that you're overwriting every call to updateList. Since you aren't creating a new point ever, this overwrites the old values. That means every element in your list will always have the most recent values, rather than the value at that time.
Also, why are you using class variables everywhere rather than passing parameters to functions? I have a feeling you don't understand Java or references very well.

Here's what your code should look like, with locals used correctly:

the toasts till "inside detectLocation" are popped up and log entries made till
04-04 00:42:34.687: V/X(10217): Response:After lm1.requestLocationUpdates
but beyond that the code is just unreachable...
even the GPS sign is shown in action bar but the toast for displaying location is not popped... pls help....!!!
In requestLocationUpdates(LocationManager.GPS_PROVIDER, 10, Two_Min, ll1) you're passing Two_Min (which you've set to 5*60*1000 = 300000) into the minDistance paramter which should be a number of metres. Try setting minDistance to 0 instead.
I am writing a code that brings current location but it is not giving me the location because it never calls onLocationChanged() .Is there any way to find the location.
mobileLocation is coming 0 for this case, so the execution goes to the else block.
My code is
public class FindLocation {
private LocationManager locManager;
private LocationListener locListener;
private Location mobileLocation;
private String provider;
public FindLocation(Context ctx){
locManager = (LocationManager) ctx.getSystemService(Context.LOCATION_SERVICE);
locListener = new LocationListener() {
#Override
public void onStatusChanged(String provider, int status,
Bundle extras) {
}
#Override
public void onProviderEnabled(String provider) {
}
#Override
public void onProviderDisabled(String provider) {
}
#Override
public void onLocationChanged(Location location) {
System.out.println("mobile location is in listener="+location);
mobileLocation = location;
}
};
locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 1, locListener);
if (mobileLocation != null) {
locManager.removeUpdates(locListener);
String londitude = "Londitude: " + mobileLocation.getLongitude();
String latitude = "Latitude: " + mobileLocation.getLatitude();
String altitiude = "Altitiude: " + mobileLocation.getAltitude();
String accuracy = "Accuracy: " + mobileLocation.getAccuracy();
String time = "Time: " + mobileLocation.getTime();
Toast.makeText(ctx, "Latitude is = "+latitude +"Longitude is ="+londitude, Toast.LENGTH_LONG).show();
} else {
System.out.println("in find location 4");
Toast.makeText(ctx, "Sorry location is not determined", Toast.LENGTH_LONG).show();
}
}
}
i run my app on real device .
i use network instead of GPS and onLocationChanged is called:
locMan.requestSingleUpdate(LocationManager.NETWORK_PROVIDER, this, null);
Do you never get a location or only as you write in your comment "sometimes it gets location but not at the time of click."?
Might be that your code is faster than LocationManager, which might not yet have called onLocationChanged(). Change your code in order to get the last known location, or wait until your locListener was called:
locManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER, 1000, 1, locListener);
mobileLocation = locManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (mobileLocation != null) {
LocationManager.NETWORK_PROVIDER need network, but it is real, not precise; if you want to use LocationManager.GPS_PROVIDER, the situation must be outdoor instead of indoor, because GPS location need satellite, if you are in any building, the satellite cannot find you!
I thing you forgot permission
<uses-permission android:name="android.permission.ACCESS_GPS" />
<uses-permission android:name="android.permission.ACCESS_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" />
OR
Declare Proper Class like
public class MyLocationListener implements LocationListener {
#Override
public void onLocationChanged(Location arg0) {
latitude = arg0.getLatitude();
longitude = arg0.getLongitude();
}
}
Directly after locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 1, locListener), add the following code:
locManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 1000, 1, locListener);

Manifest:
<service android:name=".services.AndroidLocationServices"/>
Start Service before use:
startService(new Intent(this, AndroidLocationServices.class));
In my case the app was not asking for permissions. Although I have added the permissions in menifest file. So I was not able to allow my app to access the location.
As a fix, I manually went to: Settings->Permissions->Your location and enabled the location permission for my under-development app. And that fixed my problem.
I assume that this issue is only when the app is installed through Android Studio. I hope it will not occur when the app is installed from Google Play.
I have small service implementing LocationListener. I tested it manually with my application and it works properly.
I wrote also a test case for the service.
I used setTestProviderLocation expecting that service will receive location update.
However, it does not happen.
Does anybody know what's a problem? I'd like to emphasize that the same service works in real application.
Test case is added below
