我想上傳大量的圖像到服務器說每個大小300 kb的圖像近100。當我嘗試上傳圖像時,15-18張圖像中的一些圖像會同步到服務器,但是應用程序關閉(僅存在),而logcat中沒有任何應用程序崩潰消息或錯誤。混合應用程序關閉沒有給logcat上的任何錯誤,而上傳圖像
這是一個記憶問題。可能是我沒有釋放個人圖像使用的內存。
這裏是我的同步圖像
function SyncImage(ImageName, TryCount)
{
var basicpath = localStorage.getItem('ImagePath');
var Filename = Imagename;
var src = basicpath + Filename + "?" + new Date().getTime();
// var src = "image.jpg";
var myCanvas = document.createElement('canvas');
var context = myCanvas.getContext('2d');
var img1 = document.createElement('img');
img1.onload = function()
{
var imgwidth = img1.width;
var imgheight = img1.height;
myCanvas.width = imgwidth;
myCanvas.height = imgheight;
context.drawImage(img1,10,10,imgwidth,imgheight);
//console.log("Image Ready");
// alert("Image Ready");
var myurl = myCanvas.toDataURL('image/jpeg');
urlimage = Filename + myurl;
// console.log("contacting server");
// alert("contacting server");
var nRequest = new XMLHttpRequest();
nRequest.open("POST", dbstatements.domain_address+"api/upload_image.php", true);
nRequest.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
nRequest.onreadystatechange = function (oEvent)
{
if (nRequest.readyState == 4)
{
if (nRequest.status == 200)
{
// console.log(Filename);
// alert("uploaded");
return;
}
else
{
SyncImage(ImageName, Number(TryCount+1));
}
}
};
nRequest.send(urlimage);
img1.src = " ";
img1 = null;
}
img1.src = src;
}
代碼這是我的logcat輸出

任何意見是極大的讚賞。謝謝
不,我只使用webview。我們的要求是我無法使用phonegap/cordova。有沒有解決這個問題的方法? – user6000866
我與混合應用程序合作,我總是有這個問題(內存)。嘗試爲發送文件創建自己的本機代碼。 –
因此,一旦每個圖像請求發送到服務器,我無法清除web視圖內存.... – user6000866
