从 Fragment 移动到 Activity 导致 android.os.TransactionTooLargeException

Question

I'm trying to move from a Fragment to an Activity using Intents, and where I run my code, it causes android.os.TransactionTooLargeException .

My Fragment code (CardFragment.java):

@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);

    txtName = view.findViewById(R.id.txt_name);
    btnFood = view.findViewById(R.id.btn_food);

    txtName.setText(mName);

    Bitmap bm = StringToBitMap(mImage);
    btnFood.setImageBitmap(bm);

    btnFood.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(getActivity(), Recipes.class);
            intent.putExtra("Name", mName);
            intent.putExtra("Recipe", mRecipe);
            intent.putExtra("Image", mImage);
            startActivity(intent);
        }
    });
}

The mName , mRecipe and mImage are String variables.

My Activity code (Recipes.java):

public class Recipes extends AppCompatActivity {

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

        TextView txtName = findViewById(R.id.txt_name);
        TextView txtRecipe = findViewById(R.id.txt_recipe);
        ImageView imgView = findViewById(R.id.img_view);

        txtName.setText(getIntent().getStringExtra("Name"));
        txtRecipe.setText(getIntent().getStringExtra("Recipe"));

        Bitmap bm = CardFragment.StringToBitMap(getIntent().getStringExtra("Image"));
        imgView.setImageBitmap(bm);
    }
}

Every time I run this code, I get this error message:

What is this error and how can I solve it? Maybe because there are multiple CardFragment s in my previous view? Thanks for the help.

Answer 1

也许使用 getActivity().startActivity(intent) ？

Answer 2

This error means you sending more than 1 MB of data through intent, in this case, your bitmap is too large for intent.

The solution is to reduce bitmap size or use different ways to pass bitmap like services, etc.
