Getting source code from an APK file in android

Procedure to decoding .apk files and getting source code ---->

Step 1:
Make a new folder and put .apk file (which you want to decode) now rename this .apk file with extension .zip (eg:rename from filename.apk to filename.apk.zip) and save it..now you get classes.dex files etc...at this stage you are able to see drawable but not xml and java file...so continue...(You will get xml files but that will be encoded files not showing xml code drawable dir only)

Step 2:
Now extract this zip apk file in the same folder(in this eg or case NEW FOLDER). now dowmload dex2jar from this link http://code.google.com/p/dex2jar/ and extract it to the same folder (in this case NEW FOLDER).....now open command prompt and reach to that folder (in this case NEW FOLDER)....after reaching write dex2jar classes.dex and press enter.....now you get classes.dex.dex2jar file in the same folder......now download java decompiler from http://java.decompiler.free.fr/?q=jdgui and now double click on jd-gui and click on open file then open classes.dex.dex2jar file from that folder...now you get class file...save all these class file (click on file then click "save all sources" in jd-gui)..by src name....at this stage you get source...but xml files are still unreadable...so cont...

Step 3:
Now open another new folder and put these files
put .apk file which you want to decode
download 1. apktool v1.x & 2. apktool install window from google, and put both files in the same folder.
download framework-res.apk file using google and put in the same folder (Not all apk file need framework-res.apk file)
Open a command window
Navigate to the root directory of APKtool and type the following command: apktool if framework-res.apk
apktool d "apkname".apk ("apkname" denotes filename which you want to decode)
now you get a file folder in that folder and now you can easily read xml files also.

Step 4:
It's not any step just copy contents of both folder(in this case both new folder)to the single one
and enjoy with source code...

CHECK EMAIL VALIDATIONS IN ANDROID

This is a simple example showing email validation in ANDROID.
This example uses regex for email validation.
Create a button and an edittext in your main.xml file and try this code.




import java.util.regex.Pattern;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;

public class EmailValidationDemo extends Activity   {

    EditText TF;
    public Button checkButton;

    public final Pattern EMAIL_ADDRESS_PATTERN = Pattern.compile(
              "[a-zA-Z0-9+._%-+]{1,256}" +
              "@" +
              "[a-zA-Z0-9][a-zA-Z0-9-]{0,64}" +
              "(" +
              "." +
              "[a-zA-Z0-9][a-zA-Z0-9-]{0,25}" +
              ")+"
          );
     @Override
     public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.main);

       TF=(EditText) findViewById(R.id.TF);
       checkButton=(Button) findViewById(R.id.checkButton);

        checkButton.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
               String email=TF.getText().toString();
               if(checkEmail(email))
                  Toast.makeText(EmailValidationDemo.this,"Valid Email Addresss", Toast.LENGTH_SHORT).show();
               else
                  Toast.makeText(EmailValidationDemo.this,"Invalid Email Addresss", Toast.LENGTH_SHORT).show();
        }
        });
    }
    private boolean checkEmail(String email) {
        return EMAIL_ADDRESS_PATTERN.matcher(email).matches();
    }
}

Refresh button in Android

btn_Refresh.setOnClickListener(new OnClickListener() {

public void onClick(View v) {
// TODO Auto-generated method stub
// REFRESH CODE
RefreshPageActivity.this.startActivity(getIntent());
}
});

Delete SPACE from EditText(User cant add space in beginning in edittext if user presses space)

Step-1: Add "implements TextWatcher" after Activity
eg. public class AddMoreWebsite extends Activity implements TextWatcher {


Step-2:Now Put Cursor on Red line error and Add UnImplemented methods of TextWatcher.
Eg. it Will add following Methods


public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
String result = s.toString().replaceAll(" ", "");
if (!s.toString().equals(result)) {
et_AddMoreSite.setText(result);
et_AddMoreSite.setSelection(result.length());


}
}


public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub


}


public void onTextChanged(CharSequence s, int start, int before, int count) {
// TODO Auto-generated method stub


}


Step-3: Now Add following lines in afterTextChanged(...)


String result = s.toString().replaceAll(" ", "");
if (!s.toString().equals(result)) {
et_AddMoreSite.setText(result);
et_AddMoreSite.setSelection(result.length());




Step-4: Now Put this line in onCreate() after your editText declaration.


et_AddMoreSite.addTextChangedListener(this);

Give Effects to Buttons in android

To give effect Like we feel that button has been pressed in our application, use following code.

create one xml file in your drawable directory(or where you put your images). paste this code in it and call this file in your buttons background.

<?xml version="1.0" encoding="utf-8"?>

<selector xmlns:android="http://schemas.android.com/apk/res/android">

// Button Focused Pressed
<item android:state_focused="true"
android:state_pressed="true"
android:drawable="@drawable/call_end_2" />
// Button Pressed
<item android:state_focused="false"
android:state_pressed="true"
android:drawable="@drawable/call_end_1" />
// Button Default Image
<item android:drawable="@drawable/call_end" />
</selector>

now call this file in your xml file i.e 

<Button
            android:id="@+id/btn_startcall"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/your_button_efffect_xml" />

Integrate Progress Dialog Box in android

To integrate progress dialog in android application, it shows dialog box and processing particular tasks in background. following is the code...njoy...


There are four processes in Progress dialog - 
1. onPreExecute - shows loading view to user, he cant interacts with screen.
2. doInBackground - all the processes runs in background of Loading screen of onPreExecute.
3. onProgressUpdate and - set the current progress of the progress dialog
4. onPostExecute - must contain  progressDialog.dismiss(); so that user can interacts with screen. if you want to set dynamic data which came from doInBackground method  you can put it here. so user can see it. 


Put following class in your main activity class. after completion of onCreate(). and call this in onCreate() or wherever you need to show dialog box and run process in background.


To call this class use ----->> new LoadViewTask().execute();



private class LoadViewTask extends AsyncTask<Void, Integer, Void> {
private static final int length = 0;


// Before running code in the separate thread
@Override
protected void onPreExecute() {
progressDialog = ProgressDialog.show(CheckWeb_Status.this,
"Loading...", "Loading, please wait...", false, false);


}


// The code to be executed in a background thread.
@Override
protected Void doInBackground(Void... params) {


//USER DEFINED PROCESSES THAT RUNS IN BACKGROUND ON PROGRESS DIALOG
                     // PROCESS-1
ParseJson(data);
ParseXml();


/*
* This is just a code that delays the thread execution 4 times,
* during 850 milliseconds and updates the current progress. This is
* where the code that is going to be executed on a background
* thread must be placed.
*/
try {
// Get the current thread's token
synchronized (this) {
// Initialize an integer (that will act as a counter) to
// zero
int counter = 0;
// While the counter is smaller than four
while (counter <= 4) {
// Wait 850 milliseconds
this.wait(850);
// Increment the counter
counter++;
// Set the current progress.
// This value is going to be passed to the
// onProgressUpdate() method.
publishProgress(counter * 25);
}
}
} catch (InterruptedException e) {
e.printStackTrace();
}
return null;


}


// Update the progress
@Override
protected void onProgressUpdate(Integer... values) {
// set the current progress of the progress dialog
progressDialog.setProgress(values[0]);
}


// after executing the code in the thread
@Override
protected void onPostExecute(Void result) {


// close the progress dialog
Log.v("Progress", "Entered");

Check Internet connection in android application

To check Internet connection is Ok or not? or which type of connection you are using i.e WiFi or GPRS etc...following is a code for that....njoy....and call this method in main onCreate() method.



void checkInternetConnectionStatus() {
ConnectivityManager connMgr = (ConnectivityManager) this
.getSystemService(Context.CONNECTIVITY_SERVICE);


android.net.NetworkInfo wifi = connMgr
.getNetworkInfo(ConnectivityManager.TYPE_WIFI);


android.net.NetworkInfo mobile = connMgr
.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);


if (wifi.isAvailable()) {
Toast.makeText(this, "Wi-Fi connection", Toast.LENGTH_LONG).show();
} else if (mobile.isAvailable()) {
Toast.makeText(this, "Mobile Internet", Toast.LENGTH_LONG).show();


} else {
/*
* Toast.makeText(this, "No Internet Connection", Toast.LENGTH_LONG)
* .show();
*/
new AlertDialog.Builder(this)
.setTitle("No internet connection active")
.setMessage(
"Please start internet connection and run this application.")
.setNegativeButton("Exit",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
Log.d("AlertDialog", "Negative");
finish();
}
}).show();
}
