How to Take a Photo with the Camera App And also save as thumbnail and as Full-size Photo (resize & crop customly) in SD Card Two Folders?

Question 1

Follow bellow Steps:-

1:-

private  Bitmap getScaledBitMap(String filePath, int reqWidth, int reqHeight) {

if (filePath != null && filePath.contains("file")) {
    filePath = filePath.replace("file://", "");
}
Bitmap unscaledBitmap = ScalingUtilities.decodeBitmap(getResources(), filePath, reqWidth, reqHeight, ScalingLogic.CROP);
// Part 2: Scale image
Bitmap scaledBitmap = ScalingUtilities.createScaledBitmap(unscaledBitmap, reqWidth,reqHeight, ScalingLogic.CROP);
unscaledBitmap.recycle();

return scaledBitmap;

}

2:-

public class ScalingUtilities {

 * be optimized for further scaling to the requested destination dimensions
 * and scaling logic.

save this bitmap into required folder.

Question 2

Create a File

private final int CAMERA_PIC_REQUEST=0;

 private String createNewFile()
{

 String dirctory = Environment.getExternalStorageDirectory()+"/"+"test";
    File f = new File(dirctory);
    boolean isdirectory;
    if(!f.isDirectory())
    {
        isdirectory = f.mkdir();
    }else
    {
        isdirectory = true;
    }

    if(isdirectory)
    {
        dirctory  = dirctory +"/"+Calendar.getInstance().getTimeInMillis()+"captureImage.jpg";
        f = new File(dirctory);
        if(f.isFile())
            f.delete();
        try {
            f.createNewFile();

            return dirctory;
        } catch (Exception e) {
            Utility.Toast(mActivity, "Unable to create File");
            e.printStackTrace();
        }
    }else
    {
        Utiity.Toast(AgentSignUp.this, "Unable to create Directory");
    }
    return dirctory;
}

Step 2: fire intent:

             Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            file_image = createNewFile();
            if(file_image!=null)
            {
                File file = new File(file_image);
                Uri outputFileUri = Uri.fromFile( file );
                cameraIntent.putExtra( MediaStore.EXTRA_OUTPUT, outputFileUri );
            }
    startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);

step 3: recieve in onActivity Result (check for sucess and failure)

                @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if(resultCode==RESULT_OK)
    {
        if(requestCode==CAMERA_PIC_REQUEST)
        {
            File file = new File(file_image);
            Uri outputFileUri = Uri.fromFile( file );
            doCrop(outputFileUri);// send to cropper or you can use this uri for upper code to get two size of images
        }
}
super.onActivityResult(requestCode, resultCode, data);
}
