    <p>I have the following problem that some of you must know on my android app :</p> <blockquote> <p>3288-byte external allocation too large for this process.</p> <p>Out of memory: Heap Size=5959KB, Allocated=3922KB, Bitmap Size=18614KB</p> <p>VM won't let us allocate 3288 bytes</p> </blockquote> <p>Facts : </p> <ul> <li><p>I'm creating a bitmap of the screen (so quite huge) and I manipulate it (changing size etc ...) for doing a flipping page animation.</p></li> <li><p>It crashes only on a desire HTC : on galaxy s2 and kindle fire, no problems.</p></li> <li><p>I'm already desallocating the current Bitmap everytime I create a new one with the following code : </p> <p>Bitmap old = this.bitmap;</p> <pre><code>this.bitmap = bitmap; this.invalidate(); if(old != null) old.recycle(); </code></pre></li> <li><p>I also tryied to call this function :</p> <p>public void recycle() { if (this.bitmap!=null) this.bitmap.recycle(); System.gc(); Runtime.getRuntime().gc(); }</p></li> </ul> <p>Severals time in my code, and sometimes it gets slightly better (like it crashes a little later), but that's still not good.</p> <ul> <li>I spent a lot of time on this problem, and I don't really get how to fix it. It's like on forum there is a lot of misinformation, so I'm kinda lost.</li> </ul> <p>Thanks, ask for more precision.</p> <p>Edit : </p> <p>Here is a code called a lot :</p> <pre><code>//set the foreground image with the current day Bitmap b = Bitmap.createBitmap(visibleLayout.getWidth(), visibleLayout.getHeight(),Bitmap.Config.ARGB_8888); Canvas c = new Canvas(b); visibleLayout.draw(c); viewBitmapNext.setBitmap(b); viewBitmapNext.setVisibility(View.VISIBLE); </code></pre> <p>Where viewBitmapNext is an overwritted element of the View class. The setBitmap function is described above.</p> <p>About the resizement, I do this line of code : </p> <pre><code>viewBitmapPrevious.setLayoutParams(new RelativeLayout.LayoutParams((int) (iterator - ((totalWidth - iterator) - activity.getResources().getDimension(R.dimen.margin_right))/2), RelativeLayout.LayoutParams.WRAP_CONTENT)); </code></pre> <p>Again, tell me if you you want to know more.</p>

    1. COAre you doing this just once and running into the error? Or are you running this code multiple times?

    2. CODo you bind (attach) the bitmap to any Drawable or any element of the View hierarchy? If yes, you might need to set that reference to null as well. Note that recycle() does not release memory, it merely marks the bitmap to be released (this is useful in pre-HONEYCOMB devices where bitmaps are stored on a native bitmap heap). Calling gc() will certainly not help on your problem. Moreover, these bitmap size related crashes are often not directly related to the bitmaps themselves, but rather to some other error in your code (e.g. a Drawable leak due to an Activity leak via a static variable).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
