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, Jun 13 '14 at 11:15
it is throwing error on: `bitmap = android.provider.MediaStore.Images.Media.getBitmap(cr, imageUri);` — user1619306, Jun 13 '14 at 12:17

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;

  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.

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){
 }
