我收到错误 java.lang.OutOfMemoryError 并在运行应用程序时崩溃应用程序,从服务器下载多个图像并存储到SD卡中。我在gradle中有一些更改.properties并更改行#org.gradle.jvmargs = -Xmx2048m -XX:MaxPermSize = 1024m -XX:MaxHeapSize \ = 1024m -XX:+ HeapDumpOnOutOfMemoryError -Xmx1024m -Dfile.encoding = UTF-8 。并尝试调用 System.gc(); 。但是一次又一次地得到相同的错误。如何解决这个问题。谢谢你提前。
这是我的代码
此行的错误 imagenObtenida = BitmapFactory.decodeStream(conn.getInputStream(),null,options);
Log.e("fileUrl ", " = " + fileUrl + " ImageName = " + ImageName);
URL ImgUrl = new URL(fileUrl);
HttpURLConnection conn = (HttpURLConnection) ImgUrl.openConnection();
conn.connect();
int lenghtOfImage_File = conn.getContentLength();
Log.e("lenghtOfImage_File ", " = " + lenghtOfImage_File);
System.gc();
if(imagenObtenida != null)
{
imagenObtenida.recycle();
imagenObtenida = null;
}
BitmapFactory.Options options = new BitmapFactory.Options();
options.inTempStorage = new byte[16*1024];
options.inPurgeable = true;
options.inSampleSize = 1;
imagenObtenida = BitmapFactory.decodeStream(conn.getInputStream(), null, options);
newFolder = new File(Environment.getExternalStorageDirectory().getPath() + File.separator + "classnkk_images");
File file = new File(newFolder, ImageName);
这是我的日志错误

java.lang.OutOfMemoryError:
请求的大小超过了VM限制。
此错误表示Java应用程序尝试ti分配一个数组,其大小大于堆大小。
OutOfMemoryError扩展了VirtualMachineError 类,该类指示JVM已损坏,或者资源已耗尽且无法运行。
确认您的应用程序不存储不必要的信息。 仅存储和维护所需的那些信息 正确执行Java应用程序。

答案 1 :(得分:0)
您尝试从服务器下载的图像可能很大,因此在尝试解码时,会导致OOM异常。
