我有一个外部的.hash文件,我把它作为一个简单的远程文本文件阅读:
private class getHash extends AsyncTask<String, Void, String>{
@Override
protected String doInBackground(String... params) {
String str = null;
try {
// Create a URL for the desired page
URL url = new URL(params[0]);
// Read all the text returned by the server
InputStream is = url.openStream();//The line it crashes on
InputStreamReader isr = new InputStreamReader(is);
BufferedReader in = new BufferedReader(isr);
str = in.readLine();
in.close();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return str;
}
@Override
protected void onPostExecute(String result) {
hash = result;
}
}
然后我给线程打电话:
getHash hashThread = new getHash();
hashThread.execute(new String[]{"http://www......................hash"});
在课程中执行注意到的行期间,所有停靠点都被拉出来,我被优雅的Source not found
崩溃打了一巴掌。
LogCat会出现此错误:
W/dalvikvm(724): threadid=1: thread exiting with uncaught exception (group=0x40a13300)
答案 0 :(得分:0)
您是在调试模式还是常规模式下运行它?
source not found
消息似乎表明您正试图进入没有附加源代码的代码。
你也加了
<uses-permission android:name="android.permission.INTERNET" />
到你的AndroidManifest.xml
