java在安卓中以字节的形式读取大文件

Question

我正在尝试在应用程序中实现上传功能。对于小文件，它可以正常工作。但当我试图上传大文件时，它抛出了内存不足错误

@Override
public byte[] getBody() {
   File file = new File(filepathnew);
   //  int size = (int) file.length();
   ByteArrayOutputStream baos = new ByteArrayOutputStream();
   try{
    BufferedInputStream reader = new BufferedInputStream(new FileInputStream (filepathnew));
    int read;
    byte[] buffer = new byte[32000];
    while ((read = reader.read(buffer)) >= 0) {
       baos.write(buffer, 0, read);
    }
    } catch (FileNotFoundException fnf){
       fnf.printStackTrace();
    } catch (IOException ioe){
       ioe.printStackTrace();
    }
       byte[] everything  = baos.toByteArray();
       return everything;
}

错误日志是
