Question

以下是我从Android相机获取图片的方式：

Bitmap photo = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream stream = new ByteArrayOutputStream();
byte[] byteArrayImage = stream.toByteArray();
File f;
try
{
    f = File.createTempFile("temp-file-name", ".png");
    f.createNewFile();
    FileOutputStream fos = new FileOutputStream(f);
    fos.write(byteArrayImage);
    fos.close();
} 
catch (IOException e)
{
    e.printStackTrace();
}

然后我用我创建的文件调用此函数：

public String multiPartExecute(String url, String keyOfString, String request, String keyForFile, File file)
    {
        HttpClient client = new DefaultHttpClient();
        HttpPost post = new HttpPost(url);
        MultipartEntityBuilder multipartEntity = MultipartEntityBuilder.create();
        multipartEntity.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
        multipartEntity.addPart(keyForFile, new FileBody(file)); //here is the crash
        multipartEntity.addTextBody(keyOfString, request);
        post.setEntity(multipartEntity.build());
        HttpResponse response = null;
        String line = "", output = "";

        try
        {
            response = client.execute(post);
            BufferedReader br = new BufferedReader(new InputStreamReader((response.getEntity().getContent())));

            while ((line = br.readLine()) != null)
            {
                output += line;
            }
        } 
        catch (ClientProtocolException e)
        {
            e.printStackTrace();
            return null;
        } 
        catch (IOException e)
        {
            e.printStackTrace();
            return null;
        }

        if (response.getStatusLine().getStatusCode() != 200) 
        {
            response.getStatusLine().getStatusCode();
            return null;
        }

        HttpEntity entity = response.getEntity();
        try
        {
            entity.consumeContent();
        } 
        catch (IOException e)
        {
            e.printStackTrace();
            return null;
        }

        client.getConnectionManager().shutdown();

        return output;
    }

我在这一行发生了崩溃：multipartEntity.addPart(keyForFile, new FileBody(file));。

Here is the log cat output:

我缺少什么？找不到logcat的任何想法。

注意：在注释掉对话框show方法和有问题的行之后，我在logcat中得到了这个跟踪：

您的错误在这里：

02-05 11:46:40.359: E/WindowManager(9773):  at android.app.Dialog.show(Dialog.java:277)
02-05 11:46:40.359: E/WindowManager(9773):  at com.evapp.activities.BaseActivity.showLoadingDialog(BaseActivity.java:39)

窗口泄露错误主要是因为您尝试在不再存在的活动中显示某些内容。检查这条路线。

由于您使用asyncTask经常未处理的Exceptions导致您的活动关闭，因此打开任何类型的进度对话框都会导致上述错误，因为此活动不存在。确保在发生这种情况时关闭或不关闭对话框

修改

现在我们看到您真正的错误，现在您评论了对话框：
