HttpUrlconnection in different method

To perform an HTTP PUT:
URL url = new URL("http://www.example.com/resource");
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
httpCon.setDoOutput(true);
httpCon.setRequestMethod("PUT");
OutputStreamWriter out = new OutputStreamWriter(
    httpCon.getOutputStream());
out.write("Resource content");
out.close();
httpCon.getInputStream();
To perform an HTTP DELETE:
URL url = new URL("http://www.example.com/resource");
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
httpCon.setDoOutput(true);
httpCon.setRequestProperty(
    "Content-Type", "application/x-www-form-urlencoded" );
httpCon.setRequestMethod("DELETE");
httpCon.connect();
public  HttpURLConnection getHttpConnection(String url, String type){
        URL uri = null;
        HttpURLConnection con = null;
        try{
            uri = new URL(url);
            con = (HttpURLConnection) uri.openConnection();
            con.setRequestMethod(type); //type: POST, PUT, DELETE, GET
            con.setDoOutput(true);
            con.setDoInput(true);
            con.setConnectTimeout(60000); //60 secs
            con.setReadTimeout(60000); //60 secs
            con.setRequestProperty("Accept-Encoding", "Your Encoding");
            con.setRequestProperty("Content-Type", "Your Encoding");
        }catch(Exception e){
            logger.info( "connection i/o failed" );
        }


        return con;
}
Then in your code :
public void yourmethod(String url, String type, String reqbody){
    HttpURLConnection con = null;
    String result = null;
    try {
        con = conUtil.getHttpConnection( url , type);
    //you can add any request body here if you want to post
         if( reqbody != null){  
                con.setDoInput(true);
                con.setDoOutput(true);
                DataOutputStream out = new  DataOutputStream(con.getOutputStream());
                out.writeBytes(reqbody);
                out.flush();
                out.close();

            }
        con.connect();
        BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
        String temp = null;
        StringBuilder sb = new StringBuilder();
        while((temp = in.readLine()) != null){
            sb.append(temp).append(" ");
        }
        result = sb.toString();
        in.close();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        logger.error(e.getMessage());
    }
//result is the response you get from the remote side
}
PUT
URL url = null;
try {
   url = new URL("http://localhost:8080/putservice");
} catch (MalformedURLException exception) {
    exception.printStackTrace();
}
HttpURLConnection httpURLConnection = null;
DataOutputStream dataOutputStream = null;
try {
    httpURLConnection = (HttpURLConnection) url.openConnection();
    httpURLConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
    httpURLConnection.setRequestMethod("PUT");
    httpURLConnection.setDoInput(true);
    httpURLConnection.setDoOutput(true);
    dataOutputStream = new DataOutputStream(httpURLConnection.getOutputStream());
    dataOutputStream.write("hello");
} catch (IOException exception) {
    exception.printStackTrace();
}  finally {
    if (dataOutputStream != null) {
        try {
            dataOutputStream.flush();
            dataOutputStream.close();
        } catch (IOException exception) {
            exception.printStackTrace();
        }
    }
    if (httpsURLConnection != null) {
        httpsURLConnection.disconnect();
    }
}
DELETE
URL url = null;
try {
    url = new URL("http://localhost:8080/deleteservice");
} catch (MalformedURLException exception) {
    exception.printStackTrace();
}
HttpURLConnection httpURLConnection = null;
try {
    httpURLConnection = (HttpURLConnection) url.openConnection();
    httpURLConnection.setRequestProperty("Content-Type",
                "application/x-www-form-urlencoded");
    httpURLConnection.setRequestMethod("DELETE");
    System.out.println(httpURLConnection.getResponseCode());
} catch (IOException exception) {
    exception.printStackTrace();
} finally {         
    if (httpURLConnection != null) {
        httpURLConnection.disconnect();
    }
} 

PUT example using HttpURLConnection:
URL url = null;
try {
   url = new URL("http://localhost:8080/putservice");
} catch (MalformedURLException exception) {
    exception.printStackTrace();
}
HttpURLConnection httpURLConnection = null;
DataOutputStream dataOutputStream = null;
try {
    httpURLConnection = (HttpURLConnection) url.openConnection();
    httpURLConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
    httpURLConnection.setRequestMethod("PUT");
    httpURLConnection.setDoInput(true);
    httpURLConnection.setDoOutput(true);
    dataOutputStream = new DataOutputStream(httpURLConnection.getOutputStream());
    dataOutputStream.write("hello");
} catch (IOException exception) {
    exception.printStackTrace();
}  finally {
    if (dataOutputStream != null) {
        try {
            dataOutputStream.flush();
            dataOutputStream.close();
        } catch (IOException exception) {
            exception.printStackTrace();
        }
    }
    if (httpsURLConnection != null) {
        httpsURLConnection.disconnect();
    }
}
DELETE example using HttpURLConnection:
URL url = null;
try {
    url = new URL("http://localhost:8080/deleteservice");
} catch (MalformedURLException exception) {
    exception.printStackTrace();
}
HttpURLConnection httpURLConnection = null;
try {
    httpURLConnection = (HttpURLConnection) url.openConnection();
    httpURLConnection.setRequestProperty("Content-Type",
                "application/x-www-form-urlencoded");
    httpURLConnection.setRequestMethod("DELETE");
    System.out.println(httpURLConnection.getResponseCode());
} catch (IOException exception) {
    exception.printStackTrace();
} finally {         
    if (httpURLConnection != null) {

How to import a library project in Android Studio?

In this short tutorial I would show you how to import a library project in Android Studio v1.2.1.1. The steps to do so are:
  1. Goto File -> New -> Import Module.Android Studio Add Library
  2. Source Directory -> Browse the project path.
  3. Specify the Module Name – it is used for internal project reference.Android Studio Add Library - 2
  4. Let Android Studio build the project.
  5. Open build.gradle (Module:app) file.
  6. Add the following line with your module name in place of “Volley” in the dependencies block:
  7. It should look something like this:Android Studio Add Library 3
  8. After this Android Studio would start saying “gradle files have changed since last project sync”, press the “sync now” link to start a sync.
  9. That’s all you need to do.

TabLayout (Android Design Library) Text Color

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Below will reference with our custom style -->
    <item name="android:textAppearance">@style/my_tab_text</item>
</style>

<style name="my_tab_text" parent="Base.TextAppearance.AppCompat">
    <item name="android:textColor">@android:color/holo_blue_dark</item>
</style>
And if you dont want to reference from your Apptheme you can directly specify to TabLayout using Below snippet.
 <android.support.design.widget.TabLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:tabTextAppearance="@style/my_tab_text"
            app:tabIndicatorHeight="48dp"/>

Android google map zooming and running the current location

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

package com.example.location;

import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.view.View;
import com.actionbarsherlock.app.SherlockFragmentActivity;
import com.google.android.gms.maps.CameraUpdate;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;

public class LocationActivity extends SherlockFragmentActivity implements LocationListener     {
private GoogleMap map;
private LocationManager locationManager;
private static final long MIN_TIME = 400;
private static final float MIN_DISTANCE = 1000;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.map);
    map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();

    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, MIN_TIME, MIN_DISTANCE, this); //You can also use LocationManager.GPS_PROVIDER and LocationManager.PASSIVE_PROVIDER        
}

@Override
public void onLocationChanged(Location location) {
    LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
    CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(latLng, 10);
    map.animateCamera(cameraUpdate);
    locationManager.removeUpdates(this);
}

@Override
public void onStatusChanged(String provider, int status, Bundle extras) { }

@Override
public void onProviderEnabled(String provider) { }

@Override
public void onProviderDisabled(String provider) { }
}

map.xml
<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment"/>
if you need zooming effect very close 
LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
  
/*   CameraPosition cameraPosition = new CameraPosition.Builder()
      .target(latLng).zoom(19f).tilt(70).build();
   googleMap.setMyLocationEnabled(true);
      googleMap.animateCamera(CameraUpdateFactory
              .newCameraPosition(cameraPosition));*/

Custom Kestore to upload signed APK for Playstore using SHA1

Usually when  create the google map it will run proper in locally after setting google key ,package name and SHA1 certificate fingerprint

when upload the APK to play store we have to create custom keystore, then only we will be able to upload playstore
 here when change the keystore default into custom obviously SHA1 fingerprint also will get changed
so we have to try change in eclipse


here or we can try

C:\Users\**********>keytool -list -keystore D:\APK\Keystore\oneapp.keystore
Enter keystore password:

Keystore type: JKS
Keystore provider: SUN

Your keystore contains 1 entry

oneapp, Jul 19, 2016, PrivateKeyEntry,
Certificate fingerprint (SHA1): CF:64:96:E5:A9:F9:EF:70:6F:7D:18:2B:54:36:E5:7D:
A8:5F:7A:99







There is other way of doing as follow here


Steps (for ADT):
1.Export any project (It will show you an option to create custom keystore).
enter image description here
create your keystore with an extention ".keystore" and give password android and press next.
2.enter image description here
give alias name = androiddebugkey and password = android
now press finish and your keystore is ready.
1.Go to windows -> preference
and give the path of your custom keystore file
enter image description here
