在Android中将字节数组转换为base64字符串时获取损坏的编码数据

Question

I am developing an android application in my application I wanted to convert byte array of image to base64 string .But when I am converting i get corrupted result.

This is my AsyncTask

 public class Test1 extends AsyncTask<Void, byte[], String> {
    @Override
    protected String doInBackground(Void... voids) {

        try {
            myClient2 = new Socket("192.168.1.1", 6666);

            System.out.println("a:" + myClient2);
            try {
                JSONObject jsonObject1 = new JSONObject();
                jsonObject1.put("cmd", "request_download_file");
                jsonObject1.put("file_name", filename1);
                jsonObject1.put("verification", "CVS");


                System.out.println("File name========" + filename1);

                System.out.println("b111111111111111" + jsonObject1);
                myClient2.setKeepAlive(true);
                System.out.println(myClient2.getLocalAddress() + " " + myClient2.getLocalSocketAddress() + " " + myClient2.getKeepAlive());
                System.out.println(myClient2.getKeepAlive());
                try {

                    DataInputStream dis1 = new DataInputStream(myClient2.getInputStream());

                    //reads file length from datainputstream
                    DataOutputStream dos1 = new DataOutputStream(myClient2.getOutputStream());
                    jsonReader1 = new JsonReader(new InputStreamReader(dis1));//, "UTF-8"));

                    InputStreamReader inputReader = new InputStreamReader(dis1);

                    writer1 = new OutputStreamWriter(dos1);//, StandardCharsets.UTF_8)
                    writer1.write(jsonObject1.toString());

if anyone know this please help me

Answer 1

You are using BufferedReader to receive the bytes of an image file.

That will not work as you have seen as a reader is for text data.

So do away with it.
