    //put this code in Manifest file, activity tag  
    android:screenOrientation="nosensor"  
    android:configChanges="keyboardHidden|orientation|screenSize"  

    /* or even you can do it by programmatically -- just put  
    Configuration code in onResume method before calling super  
    like this */  
    @Override  
    protected void onResume() {  
        int currentOrientation = getResources().getConfiguration()  
                                   .orientation;  
        if (currentOrientation == Configuration.ORIENTATION_LANDSCAPE)   
        {  
            setRequestedOrientation(ActivityInfo  
                        .SCREEN_ORIENTATION_SENSOR_LANDSCAPE);

startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);  
startActivity(startMain)  

11. Start/Load Activity from Activity

    //put this code where you want to load another Activity  
    Intent intent = new Intent(FirstActivty.this, SecondActivity.class);  

    //below 2 lines (Flags) are optional  
    // 1. if set, it will clear the back stack  
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);  

    // 2. If set, this activity will become the start of a new task  
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);  

    startActivity(intent);  

12. Make a Phone Call

    String mobileNo = "+9189000000";  
    String uri = "tel:" + mobileNo.trim() ;

    //add permission to Manifest file  

13. How to check WiFi is Connected or Not

public void chekcWifiConnectDisconnect() {  
  ConnectivityManager connManager = (ConnectivityManager)   
    getSystemService(CONNECTIVITY_SERVICE);  
  NetworkInfo mWifi = connManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);  

  if (mWifi.isConnected()) {  
   Log.v("Debug", "Wifi is connectd..");     
  } else {  
   Log.v("Debug", "Wifi is not connectd..");     
  }  

} 

//dont forget to put Wifi permission in manifest file  

What is Fragment in Android?

• A fragment is a class implementing a portion of an activity.
• A fragment represents a particular operation or interface running within a larger activity.
• Fragments must be embedded in activities; they cannot run independent of activities.
• Most fragments define their own layout of views that live within the activity’s view hierarchy.  
• A fragment has its own life-cycle, closely related to the life-cycle of its host activity. 
• A fragment can be a static part of an activity, instantiated automatically during the activity’s creation.
  
• Or, you can create, add, and remove fragments dynamically in an activity at run-time.

Hi Guys,

Today I am sharing the code about Google Map Android V2 and get the location on map by Geo-coding.
In this new version of Google Map Android there are many things are changed now.

1. For using  this new feature you have installed the Google Play Service in your android SDK Manager. So need to installed. After installed this feature of sdk then automatically created the the google play service library project in your default folder (sdk\extras\google\google_play_services\libproject) .
Because we need to add this library project with our new android project with Google Map.
See the screen shot.

2. Now need to create the Google API key from Google API console. 
 Before create the new Google API key you need to switch on service of Google Map Android V2 from your Google Services. Please see the screen shot.
  

 

3. Now the next step need to create the SHA1 finger print by using the keytool and your project name.
So create the the Android name folder inside the C drive (C:\Android ) of your computer. And put the two file inside this folder. 1. debug.keystore 2. keytool.exe

4. In the next step you need to run the command on cmd to generate the SHA1 finger print key by using this keystore. So the command is :
keytool -list -v -keystore "C:\Android\debug.keystore" -alias androiddebugkey -storepass android -keypass android
After run this command on cmd it will create the SHA1 finger key.

5. In this step you just copy thus SHA1 key from cmd and paste on the Google console of configure android key for API project with your android project package name.

After that your API key will show on your Google console. Now you can use that API key in your project.

6. Now need to import the Google-play -service_lib project in your eclipse. This project is stored inside the (sdk\extras\google\google_play_services\libproject).

7. So here we start the create the new project name "GoogleMapLocationAPIV2" and set the target with Google API and add the Google play servicelibrary project with this project. See the screen shot.

• Then right click of project  select , Click “Android Tools -> Add Support Library “. In the new API it is already available then no need to add. Add only in below API.

1. When decode the image via normal way.

  String imageInSD = "/sdcard/UserImages/" + userImageName;
  Bitmap bitmap = BitmapFactory.decodeFile(imageInSD);

    String imageInSD = "/sdcard/UserImages/" + userImageName;
    BitmapFactory.Options options=null;
    options = new BitmapFactory.Options();
    options.inSampleSize = 2;
    Bitmap bitmap = BitmapFactory.decodeFile(imageInSD, null, options);

2. Decode the Image from the image path via FileInputStream and FileOutputStream.

public static Bitmap convertBitmap(String path)   {

        Bitmap bitmap=null;
        BitmapFactory.Options bfOptions=new BitmapFactory.Options();
        bfOptions.inDither=false;                     //Disable Dithering mode
        bfOptions.inPurgeable=true;                   //Tell to gc that whether it needs free memory, the Bitmap can be cleared
        bfOptions.inInputShareable=true;              //Which kind of reference will be used to recover the Bitmap data after being clear, when it will be used in the future
        bfOptions.inTempStorage=new byte[32 * 1024]; 


        File file=new File(path);
        FileInputStream fs=null;
        try {
            fs = new FileInputStream(file);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }

        try {
            if(fs!=null)
            {
                bitmap=BitmapFactory.decodeFileDescriptor(fs.getFD(), null, bfOptions);
            }
            } catch (IOException e) {

            e.printStackTrace();
        } finally{ 
            if(fs!=null) {
                try {
                    fs.close();
                } catch (IOException e) {

                    e.printStackTrace();
                }
            }
        }

        return bitmap;
    }

3. First Resize the Image Size and then after Decode the Image From Image Path.

public static Bitmap decodeSampledBitmapFromPath(String path, int reqWidth,
            int reqHeight) {

        final BitmapFactory.Options options = new BitmapFactory.Options();
        options.inJustDecodeBounds = true;
        BitmapFactory.decodeFile(path, options);

        options.inSampleSize = calculateInSampleSize(options, reqWidth,
                reqHeight);

        // Decode bitmap with inSampleSize set
        options.inJustDecodeBounds = false;
        Bitmap bmp = BitmapFactory.decodeFile(path, options);
        return bmp;
        }

    public static int calculateInSampleSize(BitmapFactory.Options options,
            int reqWidth, int reqHeight) {

        final int height = options.outHeight;
        final int width = options.outWidth;
        int inSampleSize = 1;

        if (height > reqHeight || width > reqWidth) {
            if (width > height) {
                inSampleSize = Math.round((float) height / (float) reqHeight);
            } else {
                inSampleSize = Math.round((float) width / (float) reqWidth);
             }
         }

1. The encapsulation boundary must occur at the beginning of a line, i.e., following a CRLF (Carriage Return-Line Feed)
2. The boundary must be followed immediately either by another CRLF and the header fields for the next part, or by two CRLFs, in which case there are no header fields for the next part (and it is therefore assumed to be of Content-Type text/plain).
3. Encapsulation boundaries must not appear within the encapsulations, and must be no longer than 70 characters, not counting the two leading hyphens.
