Image Transaction in Android from Device To Server

Hi!

     Today lot of developer facing problem while  saving and retrieving images in Android from Device To Server and vice versa.

 This blog will be help you to solve this issue.

Step 1 :
call the gallery to select the image

Step 2 :
By using ActivityResultSet() we can receive the image

Step 3 :
Compress the image and convert into string

Code:

ImageView imv_tst_img;   // to set the output of the image
private static Bitmap Image = null; // Bitmap for handle the image compression
Button btn_rg_image;     // for action purpose
String Image_sv;           // to store the image as string

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_rg__name);
imv_tst_img=(ImageView) findViewById(R.id.imv_tst_img);
btn_rg_image=(Button) findViewById(R.id.btn_rg_image);

btn_rg_image.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
imv_tst_img.setImageBitmap(null);
if (Image != null)
Image.recycle();
Intent intent = new Intent();
intent.setType("image/*");

// to call the Gallery intent
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(
Intent.createChooser(intent, "Select Picture"), GALLERY);
}
});
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == GALLERY && resultCode != 0) {
Uri mImageUri = data.getData();
try {
// create the Bitmap by using the selected image
Image = Media.getBitmap(this.getContentResolver(), mImageUri);
ByteArrayOutputStream bao = new ByteArrayOutputStream();
Bitmap bit_map = Bitmap.createBitmap(Image, 0, 0,
Image.getWidth(), Image.getHeight());
//compress the bitmap
bit_map.compress(Bitmap.CompressFormat.JPEG, 75, bao);
//converted as byte[] array
byte[] byt_ara = bao.toByteArray();
// Encode by Base64 and save as string
String encoded_btmp = Base64
.encodeToString(byt_ara, Base64.DEFAULT);
// in mycode i pass the string for public use
Image_sv = encoded_btmp;
Log.d("Image_Save", Image_sv);
System.out.println("Image _1 : "+Image_sv);

} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

// Revers Process : method to convert the string into Bitmap and set it on the ImageViewer
public void set_Image() {
try {
byte[] decodedString = Base64.decode(Image_sv, Base64.DEFAULT);
Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString,
0, decodedString.length);
imv_tst_img.setImageBitmap(decodedByte);
} catch (Exception e) {
// TODO: handle exception
Log.d("ERROR ON IMG", e.getMessage());
}
}

Thats All..,

How To Make Launcher App in Android

Hi!

    In some situation while the employees are using android device, we need to develop application which should allow the user to use only one particular Enterprise / Business Application, it should block the other application and all activity of the device. It called as Launcher Application.

In this post i am going to give idea only about how to Restrict/Stop all other application while Android device is booting. Because if you try this on your real device all your stored data will be deleted and unable to launch any other applications except your currently launched application.

     In some Business Purpose we need to all employees should work on only one Business Application, We should stop the employee to use the official device for entertainment and other personal purposes.

Work Flow ;

1) In Android we have to stop the Actionbar , Notifications & Other Service.

2) Even if the device is booting we should run our Business application only.

Waning ;

This is not a fun, if you using this technique on your real device, your all data will be lose and this will be your permanent application..,

I have mention everything in this link download , please Download and use carefully..,

Thank You!
