拍照并获取Bitmap＆Uri-Android

Question

I have a web service which expects bitmap. Choosing from gallery option works well and uploads image to server, but I couldn't make it for Take photo

In both, I can set bitmap to my imageView before uploading (review). So, it gets bitmap and show in imageview but doesn't upload. Do you have an idea what's wrong? Thanks in advance! Here is my class;

public class TakePhoto extends AppCompatActivity implements View.OnClickListener{

private Button button, button2, button3;
private String encoded_string, image_name;
private Bitmap bitmap;
private File file;
private Uri file_uri;
private final int IMG_GALLERY = 1;
private final int IMG_CAMERA = 2;
private ImageView imageView;

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if(requestCode == IMG_GALLERY && resultCode == RESULT_OK && data != null){

        Uri uri_gallery = data.getData();
        try {
            bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri_gallery);
            imageView.setImageBitmap(bitmap);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }else if(requestCode == IMG_CAMERA && resultCode == RESULT_OK && data != null){
        Uri uri_camera = data.getData();
        try {
            bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri_camera);
            imageView.setImageBitmap(bitmap);
        } catch (IOException e) {
            e.printStackTrace();
        }


    }
}

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_take_photo);

    button = (Button) findViewById(R.id.button);
    button2 = (Button) findViewById(R.id.button2);
    button3 = (Button) findViewById(R.id.button3);
    imageView = findViewById(R.id.imageShow);
    button.setOnClickListener(this);
    button2.setOnClickListener(this);
    button3.setOnClickListener(this);
}

private void selectImage(){

    Intent intent = new Intent();
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);
    startActivityForResult(intent, IMG_GALLERY);

}

private void takeImage(){
    Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(cameraIntent, IMG_CAMERA);
}

@Override
public void onClick(View v) {

    switch (v.getId()){

        case R.id.button:
            selectImage();
            break;

        case R.id.button2:
            uploadImage();
            break;

        case R.id.button3:
            takeImage();
            break;

    }


}

private String imageToString(Bitmap bitmap){
    ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, byteArrayOutputStream);
    byte[] imgBytes = byteArrayOutputStream.toByteArray();
    return Base64.encodeToString(imgBytes,Base64.DEFAULT);
}

private void uploadImage(){

    Map<String,String> map = new HashMap<String,String>();
    map.put("encoded_string",imageToString(bitmap));
    map.put("image_name","newimage");

    API_Service api_service = Client.getRetrofitInstance().create(API_Service.class);
    Call<ResponseBody> call = api_service.sendImage(map);
    call.enqueue(new Callback<ResponseBody>() {
        @Override
        public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
            Toast.makeText(TakePhoto.this, ""+response.body().getSuccess(), Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onFailure(Call<ResponseBody> call, Throwable t) {
            Toast.makeText(TakePhoto.this, "hata", Toast.LENGTH_SHORT).show();
        }
    });

}

我已经通过压缩图像来解决问题，因为它的大小超过5MB，并且我认为字节有问题。
