我一直在android上的应用程序，应该从SD卡抓取图像，然后将其上传到我的服务器。 我能够得到图片上传到服务器使用这个例子给了“ http://www.androidexample.com/media/UploadToServer.PHP uri但是图像不会上传到我使用本地主机服务器本地主机从一个wifi从一个Android设备使用URI 192.1xx.x.xxx/uploadtoserver.PHP我收到一个serverresponse 200并确定。
我已经search了答案和研究了3天，不能得到这个工作。
我的代码：
Java部分：
dlopen（）不能使用android-n
如何确定和设置android.process.media组？

}
由于它在一台服务器上工作，我认为这是一个服务器端问题
PHP的一部分
<?PHP $target_path1 = "var/www/images/" $target_path1 = $target_path1 . basename( $_FILES['uploaded_file']['name']); if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'],$target_path1)) { echo "Success"; } else{ echo "fail";} ?>
为Android构build的共享库（.so）文件可以包含/链接并在Android应用程序中使用吗？
没有这样的文件或目录“，而试图获得亚行版本

Eclipse ADT意外的exception“无法运行程序”
<?PHP $target_path1 = "/var/www/images/" $target_path1 = $target_path1 . basename( $_FILES['uploaded_file']['name']); if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'],$target_path1)) { echo "Success"; } else { echo "fail"; } ?>
看起来你正在引用一个相对目录： var/www/images/ which，如果你的PHP文件在/var/www/开始的时候会指向/var/www/var/www/images/是你的意图。
只需更改$target_path1 ，使其成为绝对路径/var/www/images/
