FileOutputStream fOut = null; try { fOut = this.openFileOutput("employeeInformation.xml", MODE_PRIVATE); try { InputStream is = new URL("http://totheriver.com/learn/xml/code/employees.xml").openStream(); int size = is.available(); byte[] buffer = new byte[size]; is.read(buffer); is.close(); fOut.write(buffer); } catch(Exception e) { e.printStackTrace(); } } catch (FileNotFoundException e) { e.printStackTrace(); } finally { try { fOut.close(); } catch (IOException e) { e.printStackTrace(); } }
有谁知道问题是什么？
将Internet权限添加到您的清单：
<uses-permission android:name="android.permission.INTERNET"/>
你需要去你的Android应用程序项目中的Manifest文件，然后在其他权限旁边的application部分添加： android.permission.INTERNET
你的清单应该是这样的：
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="18" /> .... <uses-permission android:name="android.permission.INTERNET" /> ... <application android:allowBackup="true" ....
记住值（ android.permission.INTERNET ）是区分大小写的。
希望这可以为你节省一些时间。
