在這裏，我通過dalvikvm堆的一個.Getting錯誤下載從服務器的一個圖像：在31961104字節分配時內存運行應用程序，並在中途墜毀。一段時間圖像下載某個not.But我想從下載列表視圖中添加圖像..安卓：dalvikvm堆：內存
這裏是我的下載代碼
private Bitmap downloadBitmap(String url) {
final DefaultHttpClient client = new DefaultHttpClient();
final HttpGet getRequest = new HttpGet(url);
try {
HttpResponse response = client.execute(getRequest);
//check 200 OK for success
final int statusCode = response.getStatusLine().getStatusCode();
if (statusCode != HttpStatus.SC_OK) {
Log.w("ImageDownloader", "Error " + statusCode +
" while retrieving bitmap from " + url);
return null;
}
final HttpEntity entity = response.getEntity();
if (entity != null) {
InputStream inputStream = null;
try {
// getting contents from the stream
inputStream = entity.getContent();
// decoding stream data back into image Bitmap that android understands
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 1;
final Bitmap bitmap = BitmapFactory.decodeStream(inputStream, null, options);
// final Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
File file = new File(newFolder, imageName);
if (file.exists()) file.delete();
try
{
FileOutputStream out = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
out.flush();
out.close();
int imagenObtenidaW = bitmap.getWidth();
int imagenObtenidaH = bitmap.getHeight();
Log.e("imagenObtenidaW " ," = +" + imagenObtenidaW + " imagenObtenidaH = " + imagenObtenidaH);
} catch (Exception e) {
}
return bitmap;
} finally {
if (inputStream != null) {
inputStream.close();
}
entity.consumeContent();
}
}
} catch (Exception e) {
// You Could provide a more explicit error message for IOException
getRequest.abort();
Log.e("ImageDownloader", "Something went wrong while" +
" retrieving bitmap from " + url + e.toString());
}
return null;
}
here is my code form download in the same Activity.
if (imageName.endsWith(png_Pattern) || imageName.endsWith(jpg_pattern) || imageName.endsWith(bmp_pattern) || imageName.endsWith(gif_pattern) || imageName.endsWith(jpeg_pattern))
{
str_DownLoadUrl = namespace + "/DownloadFile/FileName/" + imageName;
Log.e("@@@@@", "str_DownLoadUrl = " + str_DownLoadUrl);
//download_PngFile(str_DownLoadUrl);
downloadBitmap(str_DownLoadUrl);
strDownLoadStatus = "1";
dbhelper.update_DownLoadStatus(imageName, strDownLoadStatus);
}
}

如何解決這個問題。
的完整鏈接的android：largeHeap = 「真」 做u設置此清單文件？ –
爲什麼不使用圖像加載庫在列表視圖中添加圖像？ –
加入'android：largerHeap =「true」'不是管理這個問題的正確方法。 –
