如何将图片从 android 应用程序上传到服务器？

Question

我开发了一小部分。它现在只能拍照不存储。我想将图片（使用相机）从android应用程序上传到服务器。我使用了改造库、网络服务（asp.net）。我该怎么做？

清单：

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

代码：

public class UploadPhotoActivity extends AppCompatActivity {
    static final int REQUEST_IMAGE_CAPTURE = 1;

    ImageView imageView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_upload_photo);

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

    }


    public void SelectPhotoMethod(View view){

        Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
            startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
        }

    }
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
            Bundle extras = data.getExtras();
            Bitmap imageBitmap = (Bitmap) extras.get("data");
            imageView.setImageBitmap(imageBitmap);
        }
    }

}
