Thanks for Vu-Nguyen's reply. I did more test, and here is some output about the err:
========= W/System.err( 1390): java.lang.NullPointerException W/System.err( 1390): at java.io.Reader.<init>(Reader.java:72) W/System.err( 1390): at java.io.InputStreamReader.<init>(InputStreamReader.java:72) W/System.err( 1390): at android.test.MyTestHttpRequest.executeHttpsPost(MyTestHttpRequest.java:262) W/System.err( 1390): at android.test.MyTestServerToolkitL.loginUser(MyTestUserServerToolkitL.java:40) W/System.err( 1390): at com.me.mytest.MyTestLoginActivity$6.run(PsLoginActivity.java:279) ========= It seems some null pointer is the reason? Is it?
