FAILED BINDER TRANSACTION while passing Bitmap fro

问题:

I want to pass a image as a bitmap from one activity to another. And i want to know whether it is possible to do like that.

Sending Activity

Intent intent = new Intent(getApplicationContext(), BitmapActivity.class);
                Bundle b = new Bundle();
                b.putParcelable("BITMAP", bitmap);
                intent.putExtras(b);
                startActivity(intent);

Receiving Activity

Bundle bb = this.getIntent().getExtras();
    b = bb.getParcelable("BITMAP");

But i am getting !!! FAILED BINDER TRANSACTION !!! Error

回答1:

You can use a global class with a static bitmap object in it, something like this:

public class Global { static Bitmap img; }

Before stating the activity by intent, assign your bitmap to this Global class attribute:

Global.img = your_bitmap_img;

After starting your activity, you can get back your bitmap by:

bitmap_in_new_activity = Global.img;

I know global variables are too dangerous for debugging but this technique helps us to transfer large data from one activity to another.The binder transaction buffer has a limited fixed size, currently 1Mb regardless of your device capabilities or your app.

Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.f1);
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
    byte[] food = stream.toByteArray();
    Intent intent = new Intent(MainActivity.this,NoBoringActionBarActivity.class);
    intent.putExtras(bundle);
    intent.putExtra("picture", food);
    startActivity(intent);  

Sending Activity

Bundle extras = getIntent().getExtras();


    byte[] food = extras.getByteArray("picture");
    Bitmap fo = BitmapFactory.decodeByteArray(food, 0, food.length);
    mHeaderLogo = (ImageView) findViewById(R.id.header_logo);
    //ImageView image = (ImageView) findViewById(R.id.header_logo);
    mHeaderLogo.setImageBitmap(fo);   

Receiving Activity

Don't forget to place your image in drawable.
