相机捕获图像共享到不同的应用程序

Question

  

我正在开发一个应用程序，其中有一部分拍摄图像   从相机，必须分享图像到不同的应用程序。我正在使用代码，但它没有共享图像。请看看，请告诉我哪里错了。

image = (ImageView)findViewById(R.id.image);

        share = (Button)findViewById(R.id.share);

        click = (Button)findViewById(R.id.click);

        click.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

                Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                startActivityForResult(intent, CAMERA_PIC_REQUEST);

            }
        });

        share.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

BitmapDrawable bitmapDrawable = (BitmapDrawable)image.getDrawable();

                Bitmap bitmap = bitmapDrawable.getBitmap();

                // Save this bitmap to a file.
                File cache = getApplicationContext().getExternalCacheDir();
                File sharefile = new File(cache, "toshare.png");
                try {
                FileOutputStream out = new FileOutputStream(sharefile);
                bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
                out.flush();
                out.close();
                } catch (IOException e) {
                }

                // Now send it out to share
                Intent share = new Intent(android.content.Intent.ACTION_SEND);
                share.setType("image/*");
                share.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://" + sharefile));
                try {
                startActivity(Intent.createChooser(share, "Share photo"));
                } catch (Exception e) {
                }

            }
        });
    }
         protected void onActivityResult(int requestCode, int resultCode, Intent data) {

                if (requestCode == CAMERA_PIC_REQUEST) {
                    //2
                    Bitmap thumbnail = (Bitmap) data.getExtras().get("data"); 
                    image.setImageBitmap(thumbnail);
                    //3
                    share.setVisibility(0);
                    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
                    thumbnail.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
                    //4
                    File file = new File(Environment.getExternalStorageDirectory()+File.separator + "image.jpg");
                    try {
                        file.createNewFile();
                        FileOutputStream fo = new FileOutputStream(file);
                        //5
                        fo.write(bytes.toByteArray());
                        fo.close();
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }

           }
         }

  }
