    <p>I wrote a program that at any time displays 8 user selected images on the screen. Each image is taken from its original form and scaled down to a uniform size. In order to do this I am using the code below:</p> <pre><code>Bitmap bitmapOrg = BitmapFactory.decodeFile(File Location Here); int width = bitmapOrg.getWidth(); int height = bitmapOrg.getHeight(); int newWidth = 100; int newHeight = 100; // calculate the scale - in this case = 0.4f float scaleWidth = ((float) newWidth) / width; float scaleHeight = ((float) newHeight) / height; // createa matrix for the manipulation Matrix matrix = new Matrix(); // resize the bit map matrix.postScale(scaleWidth, scaleHeight); // recreate the new Bitmap Bitmap resizedBitmap = Bitmap.createBitmap(bitmapOrg, 0, 0, width, height, matrix, true); // make a Drawable from Bitmap to allow to set the BitMap // to the ImageView, ImageButton or what ever BitmapDrawable bmd = new BitmapDrawable(resizedBitmap); //ImageView imageView = new ImageView(this); ImageView iv = (ImageView) findViewById(R.id.imageView1); // set the Drawable on the ImageView iv.setImageDrawable(bmd); // center the Image iv.setScaleType(ScaleType.CENTER); </code></pre> <p>Even though my code works its not perfect. It seems like I'm using up a lot of memory especially calling this code possibly 8 times at once. Where in the code would I "recycle" the memory and how could I make this code possibly run better?</p> <p><strong>EDIT:</strong></p> <p>So I implemented the code in my project and it was working perfect and then I tried to add it to other sections and it just stopped working all together. My code looks like this: any idea what am I doing wrong? </p> <pre><code> BitmapFactory.Options options = new BitmapFactory.Options(); options.outWidth = 50; options.outHeight = 50; Bitmap bitmap = BitmapFactory.decodeFile(path, options); ImageView iv = (ImageView) findViewById(R.id.imageView7); iv.setImageBitmap(bitmap); </code></pre>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
