Cannot resolve symbol HttpGet,HttpClient,HttpResponce in Android Studio

Today I was facing this issue "Cannot resolve symbol DefaultHttpClient" while parsing JSON in my application.

So Friends!! if you are also facing or will face the same issue then I'm giving you the solution for it. HttpClient was deprecated in API Level 22 and removed in API Level 23, You have to use URL Conntection. If you need SDK 23, add this to your gradle:

android {
    useLibrary 'org.apache.http.legacy'
}

Please remove all jar files of Http from libs folder and add below dependencies in gradle file:

compile 'org.apache.httpcomponents:httpclient:4.5'
compile 'org.apache.httpcomponents:httpcore:4.4.3'

Display HTML format text in WebView

I have faced this problem to show the HTML format text show in WebView
I found the solution for this and lets share it -

Create a xml with WebView

<LinearLayout 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:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:orientation="vertical"
    tools:context=".MainActivity" >

    <WebView
        android:id="@+id/webview"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

</LinearLayout>

Now create the Activity

package com.example.androidhtmltextsample;

import android.os.Bundle;
import android.app.Activity;
import android.webkit.WebView;

public class MainActivity extends Activity {

 WebView webView;
 
 String mimeType = "text/html";
 String encoding = "utf-8";
 String htmlText = "<ul>\n<li>Apple cider vinegar dries acne without causing any apparent discomfort.</li>" +
        "\n<li>Another interesting acne overnight treatment is the application of toothpaste.</li>" +
        "\n<li>Follow this up by applying a bit of alcohol over the affected area just prior to bedtime.</li>" +
        "\n<li>Do not apply gel based toothpastes on the affected areas.</li>\n</ul>";
 
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  
  webView = (WebView)findViewById(R.id.webview);
  webView.loadData(htmlText, mimeType, encoding);
 }

}

Now add the Internet Permission in Menifest file

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"    
package="com.example.androidhtmltextsample"    
android:versionCode="1"    
android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="8"        
              android:targetSdkVersion="23" />

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

    <application android:allowBackup="true"        
                 android:icon="@drawable/ic_launcher"        
                 android:label="@string/app_name"       
                 android:theme="@style/AppTheme" >
        <activity android:name="com.example.androidhtmltextsample.MainActivity"         
                  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>

Can we use strikethrough on sticky notes

The "Sticky Notes" that come with Windows7 happens to be a very good application. With this you can keep a track of your task list by scribbling stuff on it.

Well, since the font formating capabilities of these notes was not very impressive I was just wondering if there is an alternative to strikethrough/strikeout a scribbled line from the note... and guess what! It does have a shortcut... Just like Ctrl+b is for Bold and Ctrl+i is for itallic, Ctrl+t is for Strikethrough/Strikeout.

    <item>
        <layer-list>
            <item>
                <shape>
                    <stroke android:width="3dp" android:color="#ebebeb" />

                    <corners android:radius="5dp" />

                    <solid android:color="#fff"></solid>
                </shape>
            </item>
            <item>
                <bitmap android:gravity="bottom|right" android:src="@drawable/ic_arrow_drop_down" />

    android:layout_height="wrap_content"
