我遇到的问题是我开发的应用程序，它应该执行大量数据传输。当它是几个文件时效果很好但是一旦你达到MB规模，应用程序崩溃了。我目前不得不转移一堆目前导致我的应用程序崩溃的图像。
我得到的错误是。

这是我正在使用的副本：
public static File createDirectory(File path, String name) throws Exception
{
File directory = new File(path, name);
if (directory.mkdirs()) return directory;
if (directory.exists()) throw new Exception(String.format("%s already exists", name));
throw new Exception(String.format("Error creating %s", name));
}
public static File copyFile(File src, File path) throws Exception
{
try
{
if (src.isDirectory())
{
if (src.getPath().equals(path.getPath())) throw new Exception();
File directory = createDirectory(path, src.getName());
for (File file : src.listFiles()) copyFile(file, directory);
return directory;
}
else
{
File file = new File(path, src.getName());
FileChannel channel = new FileInputStream(src).getChannel();
channel.transferTo(0, channel.size(), new FileOutputStream(file).getChannel());
return file;
}
}
catch (Exception e)
{
throw new Exception(String.format("Error copying %s "+e,src.getName()));

}
转向诺克斯方法
public void movetoKnox(View view)
{
count = movefileList.size();//4
count2 = multiFile.size();//2
for (int i =0; i<count; i++)
{
for( int j=0; j<count2;j++)

File temp = new File(multiFile.get(j));
try{
copyFile(temp,chamberLocation);
}catch (Exception e)
{
Toast.makeText(moveKnox.this, "Exception:"+e,Toast.LENGTH_SHORT).show();
}
}
}
}
使用LOGCAT删除游戏和运行后
