xception: An error occurred while executing doInBackground()

android的报错提示：

E/AndroidRuntime: FATAL EXCEPTION: AsyncTask #2
                  Process: com.xiangsheng.xsface, PID: 23080
                  java.lang.RuntimeException: An error occurred while executing doInBackground()
                      at android.os.AsyncTask$4.done(AsyncTask.java:415)
                      at java.util.concurrent.FutureTask.finishCompletion(FutureTask.java:383)
                      at java.util.concurrent.FutureTask.setException(FutureTask.java:252)
                      at java.util.concurrent.FutureTask.run(FutureTask.java:271)

错误在哪，看来找不到，直接说吧 最好就是需要调试，调试时可以发现有没有提示报错，是因为调试能对你很有帮助
