I have set minimum sdk to be API21 while my virtual device run on API23. I tried to save image to server and do it on asynctask. I tried to debug the code and found out that the problem is in asyncTAsk.class

public class inserttable extends AsyncTask<Void,Void,Void>{
    String name, description,isiprice;
    ImageView isiimage;
    public inserttable(String name,String desc,String price,ImageView image) {
        this.name=name;
        this.description=desc;
        this.isiprice=price;
        this.isiimage=image;
    }

    @Override
    protected Void doInBackground(Void... voids) {
        byte[] imgbyte=imagetobyte(isiimage);
        String encodeimage= Base64.encodeToString(imgbyte,Base64.DEFAULT);

        Map<String,String> datatosend=new HashMap<>();
        datatosend.put("name",name);
        datatosend.put("image",encodeimage);
        datatosend.put("desc",description);
        datatosend.put("price",isiprice);

        connecttoserver(datatosend);

        return null;
    }

    @Override
    protected void onPostExecute(Void aVoid) {
        super.onPostExecute(aVoid);
        //kalo udah kosongin data
        title.setText(""); desc.setText(""); price.setText(""); gambar.setImageResource(R.drawable.ic_menu_gallery);
    }
}

and here is connecttoserver method

public void connecttoserver(Map<String,String> data){
    String server="http://wallshoppingcenter.000webhostapp.com/";
    String filename="saveimage.php";
    String encodeurl=encodingurl(data); //ini buat tambahi post di url e
    BufferedReader reader=null;
    try {
        URL url=new URL(server+filename);
        HttpURLConnection connection=(HttpURLConnection) url.openConnection();

        connection.setRequestMethod("POST");
        connection.setDoOutput(true);
        OutputStreamWriter writer=new OutputStreamWriter(connection.getOutputStream());
        writer.write(encodeurl);
        writer.flush();

        StringBuilder sb=new StringBuilder();
        reader=new BufferedReader(new InputStreamReader(connection.getInputStream()));

        String line;
        while ((line=reader.readLine())!=null){
            sb.append(line+"\n");
        }
        //Just check to the values received in Logcat

        Log.i("custom_check","The values received in the store part are as follows:");
        Log.i("custom_check",sb.toString());
        Toast.makeText(getContext(), "Upload Data Suceed ", Toast.LENGTH_LONG).show();

    } catch (IOException e) {
        //e.printStackTrace();
        Log.i("error koneksi: ",e.getMessage());
    }
    finnaly{
        try {
            reader.close();
        } catch (IOException e) {
            Log.i("error close reader: ",e.getMessage());
        }
    } <-- from here f8 key moved me to asyncTask.class
}

The image uploaded with no error or warning, yet when I press F8 after connect to server method it moved me to asnycTask.class with error "source code does not match byte code"

Here is the picture error on asyncTask.class

When i presss f9 the emulator said the apps is stopped(the apps never got to postexecute).

I try to search for possible solution, some says it's IDEA bug some says i need to uninstall, clean and rebuild project, disable instant run, invalidate caches and restart.

I have tried it all with no result.
