我不确定我的代码有什么问题，但每当我对getBytesFromInputStream（）进行方法调用时，它都会根据logcat停止它们，我不知道为什么。在RepeatingTask TimerTask代码中调用getBytesFromInputStream（）方法。这是代码：
变量声明：
public Socket socket = null;
public PrintWriter outputstrwr;
public OutputStream out = null;
public DataOutputStream dataOutputStream = null;
public DataInputStream dataInputStream = null;
public DataInputStream dis = null;
public DataOutputStream dos = null;
public static InputStream inputStr = null;
private String inputJSON = "";
private String outputJSON = "";
private String outputJSONserv = "";
onCreate方法（）：

super.onCreate(savedInstanceState);
setContentView(R.layout.main);

try {
Log.e(LOG_TAG, "In OnCreate() Try");

dataInputStream = new DataInputStream(socket.getInputStream());
Log.e(LOG_TAG, "Created DataInputStream");
//out = new OutputStream();
out = socket.getOutputStream();
inputStr = socket.getInputStream();
//Thread readjsonthrd = new Thread(new ReadJSONThread());

//Gets the local profile via JSON and converts into Profile type

Log.e(LOG_TAG, "Created Gson Instance" + "GetProfileJSONStr:" + p.getProfileJSONStr());

setProfile(p);
Log.e(LOG_TAG, "Converted Profile to JSON");

getBytesFromInputStream（）：
public byte[] getBytesFromInputStream(InputStream is) throws IOException {
//BEGINNING OF ADDED CODE FOR LENGTH
//dis = new DataInputStream(is);
//int length = dis.readInt();
dataInputStream = new DataInputStream(is);
int length = dataInputStream.readInt();
//END OF ADDED CODE FOR LENGTH
// Get the size of the file
//int length = is.available();
if (length > Integer.MAX_VALUE) {
// File is too large
}
// Create the byte array to hold the data
byte[] bytes = new byte[(int) length];
// Read in the bytes
int offset = 0;
int numRead = 0;
while (offset < bytes.length
&& (numRead = is.read(bytes, offset, bytes.length - offset)) >= 0) {
offset += numRead;
}
// Ensure all the bytes have been read in
if (offset < bytes.length) {
throw new IOException("Could not completely stream ");
}
// Close the input stream and return bytes
is.close();
return bytes;
}
ConvertByteArrayToString（）：
public String ConvertByteArrayToString(byte[] b) {
// byte[] to string
String input = new String(b);
return input;
}
似乎代码挂断了这一行：
inputJSON = ConvertByteArrayToString(getBytesFromInputStream(inputStr));
。任何代码或指针都会有所帮助。
