Android中的NegativeArraySizeException

我试图运行此代码，但出现错误。谁能告诉我为什么？调试器显示以下内容

线程[main]（挂起（异常NegativeArraySizeException）） ViewRoot.handleMessage（消息）行：1704 ViewRoot（处理程序）。dispatchMessage（消息）行：99 Looper.loop（）行：123 ActivityThread.main（字符串[]）行：4203 invokenactive（Object，Object[]，Class，Class[]，Class，int，boolean）行：不可用[本机方法] 调用（对象，对象…）行：521 ZygoteInit$MethodAndArgsCaller.run（）行：791 颧骨单位。主（字符串[]）行：549 NativeStart.main（字符串[]）行：不可用[本机方法]

  public void convertAudio () throws IOException {
   Log.d("FILE", "Converting Audio");
   java.io.File fileExist = new java.io.File("/sdcard/" , "test1.3gp");
   java.io.File fileNew = new java.io.File("/sdcard/" , "test2.3gp");
   if (fileNew.exists()) {
    FileInputStream fExist = new FileInputStream(fileExist); 
       FileInputStream fNew = new FileInputStream(fileNew);

       long lengthExist = fileExist.length();
       if (lengthExist > Integer.MAX_VALUE) {
             // File is too large
       }
       byte[] bytesExist = new byte[(int)lengthExist];

       int offset = 0;
       int numRead = 0;
       try {
        while (offset < bytesExist.length && (numRead=fExist.read(bytesExist, offset, bytesExist.length-offset)) >= 0) {
             offset += numRead;
        }
       } finally {


       }

       // Ensure all the bytes have been read in
       if (offset < bytesExist.length) {
             throw new IOException("Could not completely read file "+fileExist.getName());
       }


       byte[] cleanExist = convert3gpDataToAmr(bytesExist);

       long lengthNew = fileNew.length();
       if (lengthNew > Integer.MAX_VALUE) {
             // File is too large
       }
       byte[] bytesNew = new byte[(int)lengthNew];

       int offsetNew = 0;
       int numReadNew = 0;
       try {
        while (offset < bytesNew.length && (numRead=fNew.read(bytesNew, offsetNew, bytesNew.length-offsetNew)) >= 0) {
         offsetNew += numReadNew;
        }
        } finally {


        }

       // Ensure all the bytes have been read in
       if (offset < bytesNew.length) {
             throw new IOException("Could not completely read file "+fileExist.getName());
       }


       byte[] cleanNew = convert3gpDataToAmr(bytesNew);       

   }


  }

我会检查

fullAmrDataLength

是否为负值，因为

byte[] amrData = new byte[fullAmrDataLength];

---

会导致

消极的raysizeexception

@viperdududuk:这方面运气好吗？

byte[] amrData = new byte[fullAmrDataLength];
