簡單的 Android 拍照並顯示以及獲取路徑後上傳

Activity 中的代碼，我只貼出重要的事件部分代碼

    public void doPhoto(View view)
    {
        destoryBimap();
        String state = Environment.getExternalStorageState();
        if (state.equals(Environment.MEDIA_MOUNTED)) {
            Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
            startActivityForResult(intent, 1);
        } else {
            Toast.makeText(MainActivity.this, "沒有SD卡", Toast.LENGTH_LONG).show();
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data)
    {
        Uri uri = data.getData();
        if (uri != null) {
            this.photo = BitmapFactory.decodeFile(uri.getPath());
        }
        if (this.photo == null) {
            Bundle bundle = data.getExtras();
            if (bundle != null) {
                this.photo = (Bitmap) bundle.get("data");
            } else {
                Toast.makeText(MainActivity.this, "拍照失敗", Toast.LENGTH_LONG).show();
                return;
            }
        }

        FileOutputStream fileOutputStream = null;
        try {
            // 獲取 SD 卡根目錄
            String saveDir = Environment.getExternalStorageDirectory() + "/meitian_photos";
            // 新建目錄
            File dir = new File(saveDir);
            if (! dir.exists()) dir.mkdir();
            // 生成文件名
            SimpleDateFormat t = new SimpleDateFormat("yyyyMMddssSSS");
            String filename = "MT" + (t.format(new Date())) + ".jpg";
            // 新建文件
            File file = new File(saveDir, filename);
            // 打開文件輸出流
            fileOutputStream = new FileOutputStream(file);
            // 生成圖片文件
            this.photo.compress(Bitmap.CompressFormat.JPEG, 100, fileOutputStream);
            // 相片的完整路徑
            this.picPath = file.getPath();
            ImageView imageView = (ImageView) findViewById(R.id.showPhoto);
            imageView.setImageBitmap(this.photo);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (fileOutputStream != null) {
                try {
                    fileOutputStream.close();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }
    }

    /**
     * 銷毀圖片文件
     */
    private void destoryBimap()
    {
        if (photo != null && ! photo.isRecycled()) {
            photo.recycle();
            photo = null;
        }
    }
