Reusable AsyncTask

HI All!

In every android application as a developer, It may chance to call the AsyncTask for each and every execution of call the web-service.

To reduce the code, i have find way to reuse the AsyncTask, just we can create a common class for Asyctask and with the help of Interface can reuse at any n of time.



Business class for carry the web-service output & service name

/** * Created by selvaraj on 3/10/2017. */
public class Callable_Async_B {


// result is the json output as string// action_4 is the action to call (like register,login & etc..,)


String result, action_4;

public Callable_Async_B() {
    }

    public Callable_Async_B(String result, String action_4) {
        this.result = result;
        this.action_4 = action_4;
    }

    public String getResult() {
        return result;
    }

    public void setResult(String result) {
        this.result = result;
    }

    public String getAction_4() {
        return action_4;
    }

    public void setAction_4(String action_4) {
        this.action_4 = action_4;
    }
}




Interface for call around the application
/** * Created by selvaraj on 3/10/2017. */
public interface AsyncResponse {
    void ProcessFinished(Callable_Async_B j_obj);
}



























Common & Reusable Asynctask class





import android.app.Activity;
import android.app.ProgressDialog;
import android.os.AsyncTask;
import android.util.Log;
import org.apache.http.NameValuePair;
import org.apache.http.message.BasicNameValuePair;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;






/** * Created by selvaraj on 3/10/2017. */
public class MainAsyncObj extends AsyncTask<String, String, String> {

// Dialog to show while executing
ProgressDialog p_dialog;


// result & action_4 we know already// text_2_show is a value where the text can appears while execution of web-service 


String rersult_s, text_2_show, action_4;


// HashMap to carry al your parameter name & value 


HashMap<String, String> param_map;


// delegate is used to assign the Activity 


public AsyncResponse delegate = null;


// Activity to show on


Activity activity;

public MainAsyncObj(HashMap<String, String> param_map_, String text_2_show_, String action_4_, Activity activity_) {
        this.activity = activity_;
        this.text_2_show = text_2_show_;
        this.action_4 = action_4_;
        this.param_map = param_map_;
    }

    @Override    protected void onPreExecute() {
        super.onPreExecute();
        p_dialog = new ProgressDialog(activity);
        p_dialog.setMessage(text_2_show);
        p_dialog.setCancelable(false);
        p_dialog.setIndeterminate(false);
        p_dialog.show();
    }

    @Override    protected String doInBackground(String... strings) {
        JSONParser parser = new JSONParser();
        List<NameValuePair> n_pair = new ArrayList<>();
        for (String key : param_map.keySet()) {
            String value = param_map.get(key);
            n_pair.add(new BasicNameValuePair(key, value));
        }
        rersult_s = parser.GenrtHttpRequest("http://000.000.00.000/" + action_4, "POST", n_pair);
        Log.d("Callable_result", rersult_s);
        return null;
    }

    @Override    protected void onPostExecute(String s) {
        super.onPostExecute(s);
        p_dialog.dismiss();
        delegate.ProcessFinished(new Callable_Async_B(rersult_s, action_4));
    }
}












Reuse the Asynctask on Any Activity wherever you want 






// Implemet the interfacet to get the result 


public class Profile_F extends AppCompatActivity implements AsyncResponse{




// initiate the AsyncTask with parameters




HashMap<String, String> param_map = new HashMap<>();


// pass your Key Name & Value as you want


param_map.put("KEY_NAME", "VALUE");
param_map.put("KEY_NAME", "VALUE");
.... n param_map.put("KEY_NAME", "VALUE");

MainAsyncObj MAO = new MainAsyncObj(param_map,"Please Wait..,","register", this);
MAO.delegate = this;
MAO.execute();






// Result acter complete the AsyncTask


@Overridepublic void ProcessFinished(Callable_Async_B j_obj) {
    Log.d("Result",j_obj.getResult());
    Log.d("Action_4",j_obj.getAction_4());
}

Android LKN












Hi!



By using Device we can track the user by their lastknown loc (LKN).



Method To Call The LKN




private Location getLastBestLocation() {




// get the locationmanager
    LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);




// get the status of GPS
    Location locationGPS = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);




// get the status of Provider
    Location locationNet = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

    long GPSLocationTime = 0;
    if (null != locationGPS) {
        GPSLocationTime = locationGPS.getTime();
    }

    long NetLocationTime = 0;

    if (null != locationNet) {
        NetLocationTime = locationNet.getTime();
    }

    if (0 < GPSLocationTime - NetLocationTime) {
        return locationGPS;
    } else {
        return locationNet;
    }
}




// Convert the LKL as ADS




Location location = getLastBestLocation();
if (location != null) {
    latu = location.getLatitude();
    lngu = location.getLongitude();

    Geocoder geocoder;
    List<Address> addresses;
    geocoder = new Geocoder(PO_Entry.this, Locale.getDefault());

    try {
        addresses = geocoder.getFromLocation(location.getLatitude(), location.getLongitude(), 1);
        String address = addresses.get(0).getAddressLine(0);
        String city = addresses.get(0).getLocality();
        String state = addresses.get(0).getAdminArea();
        String country = addresses.get(0).getCountryName();
        String postalCode = addresses.get(0).getPostalCode();
        String knownName = addresses.get(0).getFeatureName();

        et_po_enty_loc.setText(address + " , " + city + "\n" + state + " , " + country + " , " + postalCode);
    } catch (IOException e) {
        e.printStackTrace();
    }
} else {
    et_po_enty_loc.setText("No Location Found");
}




Thank You!

Android Material Design Hero Components Transition Animations












Hi!











Material Design is a boon for
developer to make our application with smooth animation on needy places. We are
using animation based on different need like Activity, UI Components & etc.,







From android release 5.0 (Lollipop) Material design has
introduced. In this tutorial, we are going to learn about UI components
Transition (with animation effect) while move to one activity form another
activity.







     We can Transition UI components like Button, TextView, Image
& etc.., the Transitional UI components called as “Hero Components”, in
this tutorial we are going to use a Button as Hero Component.







Gradle :







dependencies {

    compile fileTree(include: ['*.jar'], dir: 'libs')

    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {

        exclude group: 'com.android.support',
module:
'support-annotations'

    })

    testCompile 'junit:junit:4.12'

}







Style 







(values/styles.xml)


<resources>



    <!-- App Theam-->

    <style name="AppMaterialTheame" parent="SuperMaterialTheme">



    </style>





    <!-- Base application theme. -->

    <style name="SuperMaterialTheme" parent="Theme.AppCompat.Light.DarkActionBar">

        <!-- Customize your theme here. -->

        <item name="windowNoTitle">true</item>

        <item name="windowActionBar">false</item>

        <item name="colorPrimary">@color/colorPrimary</item>

        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>

        <item name="colorAccent">@color/colorAccent</item>

    </style>



</resources>











(values-v21/styles.xml)


<resources>



    <!-- App Theam-->

    <style name="AppMaterialTheame" parent="SuperMaterialTheme">

        <item name="android:windowContentTransitions">true</item>

        <item name="android:windowAllowEnterTransitionOverlap">true</item>

        <item name="android:windowAllowReturnTransitionOverlap">true</item>

</resources>











ActivityOne.Java


Button fblogin;


fblogin = (Button) findViewById(R.id.fblogin);







// On click to move ActivitySecond.Java


ActivityOptions a_optn;

Intent int_edprof = new Intent(Welcome.this,EDProfile.class);



if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {

    fblogin.setTransitionName("fblogin1");

    a_optn = ActivityOptions.makeSceneTransitionAnimation(Welcome.this, Pair.create((View)fblogin,"fblogin1"));

    startActivity(int_edprof,a_optn.toBundle());

} else {

    startActivity(int_edprof);

}















ActivitySecond.Java


Button btn_test;


btn_test = (Button) findViewById(R.id.btn_test);






if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {

    btn_test.setTransitionName("fblogin1");

} else {

}











The both activity having the different button and the button become
common for both activity by set the common name 



Eg: setTransitionName("fblogin1");



















That’s All..,







Please Leave Your Comment..,











Enjoy the code..,
