            try {
                if (resultCode == RESULT_OK) {
                    // we need to update the gallery by starting MediaSanner service.
                    mScanner = new MediaScannerConnection(ProfilePicFromCamera.this,new MediaScannerConnection.MediaScannerConnectionClient()
                    {
                       public void onMediaScannerConnected() {
                           mScanner.scanFile(imageUri.getPath(),null /*mimeType*/);
                    }

                            if (path.equals(imageUri.getPath())) {
                                mScanner.disconnect();
                                ProfilePicFromCamera.this.runOnUiThread(new Runnable() {
                                        public void run() {
                                            updateUI();
                                    }

                        file.deleteOnExit();

Answer 1

    public void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);

           if (requestCode == CAMERA_REQUEST  && resultCode == getActivity().RESULT_OK)       {
                   File file = new File(mCapturedImagePath);
                   file.delet();
            }
    }

or  u can use only this(as your condition)
File file = new File(mCapturedImagePath);
file.delet();

使用下面的代码它可以帮助你。

File fdelete = new File(file_dj_path);
    if (fdelete.exists()) {
        if (fdelete.delete()) {
            System.out.println("file Deleted :" + file_dj_path);
        } else {
            System.out.println("file not Deleted :" + file_dj_path);
        }
    }

下面是删除图像后刷新图库的代码

sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED,
 Uri.parse("file://" +  Environment.getExternalStorageDirectory())));

Answer 3

File file = new File(Environment.getExternalStorageDirectory()+"image_name"); //if your image is directly inside sdcard
file.delete();
