Image Download using asynchronous task

hi guys image download using asynchronous very easy. The below coding very useful to all

AsyncTaskRunnerObject runner = new AsyncTaskRunnerObject(this);
runner.execute(Partnerdownloadurl,userid);//update

Partnerdownloadurl = Download url (passing parameter )
userid = userid is the login member id



class AsyncTaskRunnerObject extends AsyncTask<String,String,String> {
    private String resp,Memberid,AsyType,OBJID;
    private Context myCtx;
    public AsyncTaskRunnerObject(Context ctx){
        this.myCtx = ctx;
    }
    @Override    protected void onPreExecute() {
        Log.e("Pre Execute","Pre Execute");
    }
    @Override    protected void onPostExecute(String s) {
        Log.e("Post Execute",""+s);
        StorePreference.SinglewritePreference(myCtx, "LOCAL_FEMALE_PROFILE_IMAGE", s);
    }
    @Override    protected String doInBackground(String... params) {
        HttpURLConnection urlConnection = null;
        try {
            URL uri = new URL(params[0]);
            Memberid = params[1];
            urlConnection = (HttpURLConnection) uri.openConnection();
            urlConnection.setRequestMethod("GET");
            int statusCode = urlConnection.getResponseCode();

Deleting files from a folder - android

Very simple delete the file from folder for particular format

File dir = new File(Environment.getExternalStorageDirectory() + "/Pictures/.Twogether/Videos");
        if (dir.isDirectory()) {
            String[] children = dir.list();
            for (int i = 0; i < children.length; i++) {
                if (new File(dir, children[i]).getAbsolutePath().endsWith("3gp2")) {

How to create custom font for Text View

Hi guys i am going to explain custom font for TextView

First We have create assets directory inside the main directory and then create fonts directory inside the assets main->assets->font->  then put the font file inside the font directory

Then create the below file inside any one package. The below file created in com.crm.common package

package com.crm.Common;

import android.content.Context;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.widget.TextView;

/** * Created by Ashok on 11/19/2015. */public class CustomReqularTextView extends TextView {
    public static Typeface FONT_NAME;


    public CustomReqularTextView(Context context) {
        super(context);
        if(FONT_NAME == null) FONT_NAME = Typeface.createFromAsset(context.getAssets(), "fonts/OpenSans-Regular_0.ttf");
        this.setTypeface(FONT_NAME);
    }
    public CustomReqularTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        if(FONT_NAME == null) FONT_NAME = Typeface.createFromAsset(context.getAssets(), "fonts/OpenSans-Regular_0.ttf");
        this.setTypeface(FONT_NAME);
    }
    public CustomReqularTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        if(FONT_NAME == null) FONT_NAME = Typeface.createFromAsset(context.getAssets(), "fonts/OpenSans-Regular_0.ttf");
        this.setTypeface(FONT_NAME);
    }
}

Then We have to use like

<com.crm.Common.CustomBoldTextView    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:id="@+id/compid"    android:text="@string/compname"    android:layout_gravity="center_horizontal"/>

Get Phone email


cur.getString(cur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));

First We have to add below  permission in Adroidmanifast.xml

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

activity_main.xml

Call Java function from JavaScript over Android WebView

Hi guys Here I am going to explain how to call a java function from webview

          

Step 1)MainActivity .java

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;

public class MainActivity extends Activity {
WebView webView;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final Activity MyActivity = this;
webView= (WebView) findViewById(R.id.webView);
getWindow().setFeatureInt(Window.FEATURE_PROGRESS,
Window.PROGRESS_VISIBILITY_ON);
webView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {

MyActivity .setTitle("Loading...");
MyActivity .setProgress(progress * 100);

if (progress == 100)
MyActivity .setTitle("Android Dhina");
}
});
webView.setWebViewClient(new WebViewClient());
webView.addJavascriptInterface(new WebAppInterface(this), "Android");

webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("file:///android_asset/web.html");

}

public class WebAppInterface {

Context context;

WebAppInterface(Context c) {
context= c;
}

public void showToast(String toast) {
Toast.makeText(context, toast, Toast.LENGTH_SHORT).show();
}

}

}

Step 2)activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin">

    <WebView
        android:id="@+id/webview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</RelativeLayout>


Step 3)assets/web.html

 <!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width; user-scalable=0;" />
<title>Android Dhina</title>
