I am getting unhandled exception java.io.IOExceptionat compile time. I have posted the code below and pointed out the error line. I searched many post regarding to this issue but I don't get any relevant solution.
我java.io.IOException在编译时遇到未处理的异常。我已经发布了下面的代码并指出了错误行。我搜索了很多关于这个问题的帖子，但我没有得到任何相关的解决方案。
MainActivity.java:
主活动.java：
public class MainActivity extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
...................
}
public void startRecording() throws IOException {
..................
}
player.setOnCompletionListener(new OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
if (RecordFile != null && ifexist.equals("true")) {
}
else {
if (isRecclicked == true) {
recordButtonPressed = true;
try {
new Timer().schedule(new TimerTask() {
@Override
public void run() {
// this code will be executed after 2 seconds
startRecording(); ----> Unhandled Exception java.io.iOException
}
}, 2000);
}
catch (IOException e) {
e.printStackTrace();
}
}
}
}

try {
startRecording();
}catch(IOException ex) {
//Do something with the exception
}

You call startRecording(), which, I assume, can throw an IOException, but you didn't specify that an IOExceptioncan occur inside public void run(). It should be fixed if you surround startRecording()with a try-catch block.
您调用startRecording()，我假设它可以抛出一个IOException，但您没有指定 anIOException可以出现在public void run(). 如果你startRecording()用 try-catch 块包围它应该是固定的。
