hi. I am trying to make an app where I get and store the location of
the user along with some other info entered by the user.
My code is as follows:
package com.DuckTag;
import android.app.Activity;
import android.os.Bundle;
import android.location.Criteria;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class DuckTagActivity extends Activity implements
LocationListener{
/** Called when the activity is first created. */
private String type = "Type";
private String cname = "cname";
private String snameFirst = "snameFirst";
private String snameLast = "snameLast";
private String color = "color";
private float weight = 0;
private String location = " ";
private EditText DuckType;
private EditText CommonName;
private EditText ScientificName;
private EditText Color;
private EditText Weight;
private EditText MyLocation;
private Button Locate;
private LocationManager locationManager;
private String bestProvider;
private static String tag = "dmotion";
private OnClickListener locateListener = new OnClickListener() {
public void onClick(View v) {
try {
Log.e(tag,"tag button clicked");
// Store user inputs in class fields
type = DuckType.getText().toString();
cname = CommonName.getText().toString();
snameFirst = ScientificName.getText().toString();
snameLast =
snameFirst.substring(snameFirst.lastIndexOf("
"));
snameFirst = snameFirst.substring(0,snameFirst.indexOf("
"));
color = Color.getText().toString();
weight =
Float.valueOf((Weight.getText().toString()).trim()).floatValue();
Locate.setOnClickListener(locateListener);
Log.e(tag,"inputs converted to text");
//Get user's location
locationManager = (LocationManager)
getSystemService(LOCATION_SERVICE);
Criteria criteria = new Criteria();
bestProvider = locationManager.getBestProvider(criteria,
false);
Log.e(tag,bestProvider);
Location currentLocation =
locationManager.getLastKnownLocation(bestProvider);
if(currentLocation != null) {
Toast.makeText(getApplicationContext(),
"not null",
Toast.LENGTH_LONG);
location =
Double.toString(currentLocation.getLatitude()) + " " +
Double.toString(currentLocation.getLongitude());
Toast.makeText(getApplicationContext(),
location,
Toast.LENGTH_LONG);
MyLocation.setText(location);
}
else {
Toast.makeText(getApplicationContext(),
"null",
Toast.LENGTH_LONG);
Log.e(tag,"currentLocation is null");
}
} catch (Exception e) {
Log.e(tag,e.getMessage());
}
}
};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Log.e(tag, "activity created");
try {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
DuckType = (EditText) findViewById(R.id.DuckType);
CommonName = (EditText) findViewById(R.id.CommonName);
ScientificName = (EditText) findViewById(R.id.Scientificame);
Color = (EditText) findViewById(R.id.Color);
Weight = (EditText) findViewById(R.id.Weight);
MyLocation = (EditText) findViewById(R.id.MyLocation);
Locate = (Button) findViewById(R.id.Locate);
Locate.setOnClickListener(locateListener);
Log.e(tag,"xml objects assigned");
/*
* type = DuckType.getText().toString();
* cname = CommonName.getText().toString();
* snameFirst = ScientificName.getText().toString();
* Log.e(tag,Integer.toString(snameFirst.lastIndexOf(" ")));
* snameLast = snameFirst.substring(snameFirst.lastIndexOf("
"));
* Log.e(tag,"1");
* snameFirst = snameFirst.substring(1,snameFirst.indexOf("
"));
* Log.e(tag,"2");
* color = Color.getText().toString();
* weight =
Float.valueOf((Weight.getText().toString()).trim()).floatValue();
* Locate.setOnClickListener(locateListener);
* Log.e(tag,"inputs converted to text");
*/
} catch (Exception e) {
Log.e(tag,e.toString());
Log.e(tag,e.getMessage());
}
}
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
}
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
public void onStatusChanged(String provider, int status, Bundle
extras) {
// TODO Auto-generated method stub
}
}
My android manifest is:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android";
package="com.DuckTag"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" />
<uses-permission
android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission
android:name="android.permission.ACCESS_COARSE_LOCATION" />
<application android:icon="@drawable/icon" android:label="@string/
app_name">
<activity android:name=".DuckTagActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category
android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
I am getting a Socket exception: address family not supported by
protocol error when I try to send location from emulator controller in
DDMS perspective in Eclipse. Does my code achieve the objective? Where
am I going wrong?
