Out of memory error in android bitmap

Question

I am using a bitmap. It throws out of memory error (2 out of 5 times). How can it be avoided.

Following is my code:

 bitmap = android.provider.MediaStore.Images.Media.getBitmap(cr, imageUri); photo_new= rotateImage(bitmap, 90); ByteArrayOutputStream stream = new ByteArrayOutputStream(); photo_new.compress(Bitmap.CompressFormat.JPEG, 100, stream); byte[] byteArray = stream.toByteArray(); Intent i = new Intent(getApplicationContext(),new_class.class); i.putExtra("image", byteArray); startActivity(i); byteArray=null;

It works fine on different images? What are the differences. And at which point it throws memory error? — Eypros

You are getting OutOfMemoryError because you haven't recycle those bitmaps you used

try to recycle those bitmaps after you used them

bitmap = android.provider.MediaStore.Images.Media.getBitmap(cr, imageUri); photo_new= rotateImage(bitmap, 90); ByteArrayOutputStream stream = new ByteArrayOutputStream(); photo_new.compress(Bitmap.CompressFormat.JPEG, 100, stream); byte[] byteArray = stream.toByteArray(); bitmap.recycle(); Intent i = new Intent(getApplicationContext(),new_class.class); i.putExtra("image", byteArray); startActivity(i); byteArray=null;

Am using the above code without any modification, but unfortunately first line itself giving me OutOffMemory error. MediaStore.Images.Media.getBitmap(cr, imageUri); //in this line it is crashed

 byte[] byteArray = stream.toByteArray();

in that line your ram is getting filled by whole Bitmap. Change bitmap quality from 100 to 50-60 as below

 photo_new.compress(Bitmap.CompressFormat.JPEG, 50, stream);

or

 photo_new.compress(Bitmap.CompressFormat.JPEG, 60, stream);

try both and see the results.

wrong

1). Bitmap quality is high.

2). you are not using try catch.

Suggestions

1). reduce the quality of bitmap to 45-50.

2). use try catch block to prevent your app from crash.

Solution // sender activity

try{ Intent _intent = new Intent(this, newscreen.class); Bitmap _bitmap; // your bitmap ByteArrayOutputStream _bs = new ByteArrayOutputStream(); _bitmap.compress(Bitmap.CompressFormat.PNG, 50, _bs); i.putExtra("byteArray", _bs.toByteArray()); startActivity(i); }catch(Exception e){ }

receiver activity

try{ if(getIntent().hasExtra("byteArray")) { ImageView _imv= new ImageView(this); Bitmap _bitmap = BitmapFactory.decodeByteArray(getIntent().getByteArrayExtra("byteArray"),0,getIntent().getByteArrayExtra("byteArray").length); _imv.setImageBitmap(_bitmap); } }catch(Exception e){ }
