as stacktrace said:
caused by: java.lang.securityexception: permission denied (missing internet permission?) you need add internet permission inside manifest file.
<uses-permission android:name="android.permission.internet" /> another problem is:
caused by: libcore.io.gaiexception: getaddrinfo failed: eai_nodata (no address associated hostname) probably need check hostname using sending request. (http://xxxx/photo.php)
