How to fix this error in my logcat...

org.json.JSONException: Value of type java.lang.String cannot be converted to JSONObject

Your data return ... HTML format, it 's not JSON format. You must be sure your data reuturn JSON. Maybe your request is not correct. — RoShan Shan

your string which is logged in the clip is in HTML format, not JSON.

JSONObject jobj = new JSONObject();
try {
     jobj = new JSONObject(string);
} catch (JSONException e) {
     //e.printStackTrace();
}

will give you a json object if your input is in correct json format

I fix my first error and now my error is JSONException: End of input at character 0.

that usually means empty/null string was parsed, show the string you're passing now

try {

    JSONObject jsonObject = new JSONObject(YOUR_STRING);
} 
catch (JSONException e) {
   e.printStackTrace();
}
