OutOfMemoryError using bitmap setImageUri

Android: Strange out of memory issue while loading an image to a Bitmap object
OutOfMemoryError: bitmap size exceeds VM budget :- Android
I have an application where users can take pictures or use one already existing in the gallery, and attach to a news, after saving the news in the database (I am only saving the image path content :/ / ...), I display all news in a ListView with an image title and date. to display the images in the adapter I'm using the following:
...
image.setImageURI(null);
System.gc();
image.setImageURI(Uri.parse(noticia.getIMAGEM()));
...
however even using the System.gc (); each new image that is loaded'm getting
12-12 14:59:37.239: E / AndroidRuntime (4997): java.lang.OutOfMemoryError: bitmap size exceeds performer VM budget
also already tried using
image.setImageURI(null);
System.gc();
in onResume(), onPause(), onDestroy(), but nothing worked.
also read this post: [link][1]
if(!((BitmapDrawable)image.getDrawable()).getBitmap().isRecycled()){
((BitmapDrawable)image.getDrawable()).getBitmap().recycle();
}
Bitmap thumbnail = null;
try {
thumbnail = MediaStore.Images.Media.getBitmap(context.getContentResolver(), Uri.parse(img));
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
image.setImageBitmap(thumbnail);
but then I get the following error:
12-12 15:28:42.879: E/AndroidRuntime(5296): java.lang.RuntimeException: Canvas: trying to use a recycled bitmap android.graphics.Bitmap@40756520
and besides when my list view to scroll up and down it keeps crashing, I believe that it is requesting the images ..
I do not know what else to do, any tips?
EDIT:
I found another post in the same solution to this problem worked perfectly, however I believe it would need a cache for the images because when scrolling the list up or down the one she fought, and this is very bad for the User Experience . Any idea to solve?
the following code:
in adapter: ...
String imagePath = getPath(Uri.parse(img));
image.setImageBitmap(decodeSampledBitmapFromResource(imagePath, 85, 85));
...
methods:
public String getPath(Uri uri)
{
Cursor cursor = context.getContentResolver().query(uri, null, null, null, null);
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
return cursor.getString(idx);
}
public static int calculateInSampleSize(
BitmapFactory.Options options, int reqWidth, int reqHeight) {
// Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
int inSampleSize = 2;
if (height > reqHeight || width > reqWidth) {
if (width > height) {
inSampleSize = Math.round((float)height / (float)reqHeight);
} else {
inSampleSize = Math.round((float)width / (float)reqWidth);
}
}
return inSampleSize;
}
public static Bitmap decodeSampledBitmapFromResource(String resId,
int reqWidth, int reqHeight) {
// First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(resId, options);
// Calculate inSampleSize
options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
return BitmapFactory.decodeFile(resId, options);
}
It sounds like you want to ge thumbnail from local gallery. There is a better solution directly provided by the SDK :
// First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
Bitmap thumbnail = Thumbnails.getThumbnail(context.getContentResolver(), /*ID of the local item*/, Thumbnails.MINI_KIND, options);
// Calculate inSampleSize
options.inSampleSize = UIUtils.calculateInSampleSize(options, reqWidth, reqHeight);
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
thumbnail = Thumbnails.getThumbnail(context.getContentResolver(), /*ID of the local item*/, Thumbnails.MINI_KIND, options);
