how to extract code of apk file.

step 1:

Download dex2jar here. Create a new java project and paste (dex2jar-0.0.7.11-SNAPSHOT/lib ) jar files .

Copy apk file into  newly created java project

Run it and after refresh the project ,you get jar file .Using java decompiler you can view all java class files

step 2: Download java decompiler here

 One more way

1. Download Dex2Jar zip from this link :http://code.google.com/p/dex2jar/
2. Unzip the downloaded zip file.
3. Open command prompt & write the following command on reaching to directry where dex2jar exe is there and also copy the apk in same directory.
   dex2jar targetapp.apk file(./dex2jar app.apk on terminal)
4. http://java.decompiler.free.fr/?q=jdgui download decompiler from this link.
5. Open ‘targetapp.apk.dex2jar.jar’ with jd-gui File > Save All Sources to sava the class files in jar to java files.

Go homeActivity with FLAG_ACTIVITY_CLEAR_TOP in android

It sets the FLAG_ACTIVITY_CLEAR_TOP flag on the Intent along with the HomeActivity.  This flag  launches a new instance of the activity if it isn’t currently running, and closes all the activities on top of it.

public static void goHome( Context ctx )
{
    if ( ! ( ctx instanceof HomeActivity ) )
    {
        Intent intent = new Intent( ctx, HomeActivity.class );
        intent.setFlags( Intent.FLAG_ACTIVITY_CLEAR_TOP );
        ctx.startActivity( intent );
    }

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        txtview=(TextView)findViewById(R.id.txtview);

        myThread();

    }

    public void myThread(){

     Thread th=new Thread(){

       

      @Override

      public void run(){

       try

       {

        while(true)

        {

        Thread.sleep(100);

 

 

           RunOnUiThreadExample.this.runOnUiThread(new Runnable() {

             

         @Override

         public void run() {

          // TODO Auto-generated method stub

         // do ur UI work

          txtview.setText("my name is umer and i am android developer");

         }

        });

Sort listview by title Android

Collections.sort(mylistArray, new Comparator<Object>(){
             public int compare(Object o1, Object o2) {
                 HashMap<?, ?> map1=(HashMap<?, ?>)o1;
                 HashMap<?, ?> map2=(HashMap<?, ?>)o2;
                 String s1=(String)map1.get("title");
                 String s2=(String)map2.get("title");
                 return s1.compareToIgnoreCase(s2);
             }
         });
mylistArray have sorted by title. now use sorted array in ur ListView adapter.
