Android:java.lang.OutOfMemoryError无法分配360318346字节的分配，其中包含5802592个可用字节和87MB，直到OOM

我正在处理从服务器到客户端的传输文件示例。当我尝试传输大文件（示例中我有500mb视频文件）时，它显示错误Android:java.lang.OutOfMemoryError未能分配360318346字节分配，5802592个空闲字节和87MB，直到OOM。请帮我解决这个错误

服务器端的一些和平的代码

 public class FileTxThread extends Thread {
    Socket socket;
    FileTxThread(Socket socket){
        this.socket= socket;
    }

    @Override
    public void run() {
        File file = new File(Environment.getExternalStorageDirectory(),"RAHASYA.mp4");


        byte[] bytes = new byte[(int) file.length()];


        BufferedInputStream bis;
        try {
            bis = new BufferedInputStream(new FileInputStream(file));
            bis.read(bytes, 0, bytes.length);
            OutputStream os = socket.getOutputStream();
            os.write(bytes, 0, bytes.length);
            os.flush();
           // socket.close();

            final String sentMsg = "File sent to: " + socket.getInetAddress();

            MainActivity.this.runOnUiThread(new Runnable() {

                @Override
                public void run() {
                    Toast.makeText(MainActivity.this,sentMsg,Toast.LENGTH_LONG).show();

                }});

private class ClientRxThread extends Thread {
    String dstAddress;
    int dstPort;

    ClientRxThread(String address, int port) {
        dstAddress = address;
        dstPort = port;
    }

    @Override
    public void run() {
        Socket socket = null;

        try {
            socket = new Socket(dstAddress, dstPort);

            out.println("Sockt "+socket.getInetAddress());

            File file = new File(Environment.getExternalStorageDirectory(),"RAHASYA.mp4");


            byte[] bytes = new byte[1024];


            InputStream is = socket.getInputStream();
         BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(file));
            while (true) {
                int bytesRead = is.read(bytes);
                if (bytesRead < 0) break;
                bos.write(bytes, 0, bytesRead);
                // Now it loops around to read some more.
            }
            bos.close();


            MainActivity.this.runOnUiThread(new Runnable() {

                @Override
                public void run() {
                    Toast.makeText(MainActivity.this,"Finished",Toast.LENGTH_LONG).show();
                }});

客户端需要一些代码

 public class FileTxThread extends Thread {
    Socket socket;
    FileTxThread(Socket socket){
        this.socket= socket;
    }

    @Override
    public void run() {
        File file = new File(Environment.getExternalStorageDirectory(),"RAHASYA.mp4");


        byte[] bytes = new byte[(int) file.length()];


        BufferedInputStream bis;
        try {
            bis = new BufferedInputStream(new FileInputStream(file));
            bis.read(bytes, 0, bytes.length);
            OutputStream os = socket.getOutputStream();
            os.write(bytes, 0, bytes.length);
            os.flush();
           // socket.close();

            final String sentMsg = "File sent to: " + socket.getInetAddress();

            MainActivity.this.runOnUiThread(new Runnable() {

                @Override
                public void run() {
                    Toast.makeText(MainActivity.this,sentMsg,Toast.LENGTH_LONG).show();

                }});

private class ClientRxThread extends Thread {
    String dstAddress;
    int dstPort;

    ClientRxThread(String address, int port) {
        dstAddress = address;
        dstPort = port;
    }

    @Override
    public void run() {
        Socket socket = null;

        try {
            socket = new Socket(dstAddress, dstPort);

            out.println("Sockt "+socket.getInetAddress());

            File file = new File(Environment.getExternalStorageDirectory(),"RAHASYA.mp4");


            byte[] bytes = new byte[1024];


            InputStream is = socket.getInputStream();
         BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(file));
            while (true) {
                int bytesRead = is.read(bytes);
                if (bytesRead < 0) break;
                bos.write(bytes, 0, bytesRead);
                // Now it loops around to read some more.
            }
            bos.close();


            MainActivity.this.runOnUiThread(new Runnable() {

                @Override

                    Toast.makeText(MainActivity.this,"Finished",Toast.LENGTH_LONG).show();
                }});

服务器端的字节数组太大，请将其改小，然后重试？
供参考：

  File file = new File(Environment.getExternalStorageDirectory(),"RAHASYA.mp4");
    byte[] bytes = new byte[2048];
    BufferedInputStream bis;
    try {
        bis = new BufferedInputStream(new FileInputStream(file));
        OutputStream os = socket.getOutputStream();
        int read = bis.read(bytes, 0, bytes.length);
        while (read!=-1){
            os.write(bytes, 0, read);
            os.flush();
            read = bis.read(bytes, 0, bytes.length);
        }

        //...and so on

你的问题是线路

byte[]bytes=新字节[（int）file.length（）]；

您正在创建一个与整个文件大小相同的数组。您需要一次读取一点。

是的，先生，但请给我一些如何读取文件的提示，我确实尝试过，但我不知道它是对是错，因为它不起作用，请帮助。谢谢先生。在客户端执行您正在执行的操作，但在服务器端执行（将读取更改为写入obv）。如何更改。我是初学者，我不知道服务器端代码的更改位置。请帮助我。谢谢！更改此代码：byte[]bytes=new byte[（int）file.length（）；请告诉我这一行需要添加哪些代码byte[]bytes=new byte[（int）file.length（）。谢谢！
