Question

I'm building an android application which first, users are register account with an id and then login where the system will checked if this user is using the same device as they use when registered. When the device are the same, then system will send a token to server. this is the method when checking the users device:

private void cekDataLogin(final String serial, final String device) throws IOException, JSONException {
    @SuppressLint("StaticFieldLeak")
    class dataLogin extends AsyncTask<Void, Void, String> {
        private final WeakReference<MainActivity> mActivityRef;
        private dataLogin(MainActivity activity) {
            mActivityRef = new WeakReference<>(activity);
        }
        protected String doInBackground(Void[] params) {
            String response = "";
            HashMap<String, String> map = new HashMap<>();
            try {
                HttpRequest req = new HttpRequest(ipAddress + "/preserv/index.php?func=tokenget&ser=" + serial + "&dev=" + device);
                response = req.prepare(HttpRequest.Method.GET).sendAndReadString();
            } catch (Exception e) {
                response = e.getMessage();
            }
            return response;
        }
        protected void onPostExecute(String result) {
            onTaskCompletedPin(result, jsoncode);
        }
    }
    new dataLogin(this).execute();
}
public void onTaskCompletedPin(String response, int serviceCode) {
    Log.d("responsejson", response);
    switch (serviceCode) {
        case jsoncode:
                try {
                    postDataToken();
                } catch (IOException e) {
                    e.printStackTrace();
                } catch (JSONException e) {
                    e.printStackTrace();
                }
    }
}

this is the method when sending new token:

 private void postDataToken() throws IOException, JSONException {
    final String android_id = Secure.getString(getApplicationContext().getContentResolver(), Secure.ANDROID_ID);
    final String token = SharedPreference.getInstance(MainActivity.this).getDeviceToken();
    @SuppressLint("StaticFieldLeak")
    class dataToken extends AsyncTask<Void, Void, String> {
        private final WeakReference<MainActivity> mActivityRef;
        private dataToken(MainActivity activity) {
            mActivityRef = new WeakReference<>(activity);
        }
        protected String doInBackground(Void[] params) {
            String response = "";
            HashMap<String, String> map = new HashMap<>();
            try {
                HttpRequest req = new HttpRequest(ipAddress + "/preserv/index.php?func=devuptoken&ser=" + Build.SERIAL + "&dev=" + android_id + "&token=" + token);
                response = req.prepare(HttpRequest.Method.POST).withData(map).sendAndReadString();
            } catch (Exception e) {
                response = e.getMessage();
            }
            return response;
        }
        protected void onPostExecute(String result) {
            onTaskCompletedDevice(result, jsoncode);
        }
    }
    new dataToken(this).execute();
}
public void onTaskCompletedDevice(String response, int serviceCode) {
    Log.d("responsejson", response);
    switch (serviceCode) {
        case jsoncode:
            if (response.contains("sukses")) {
                final String android_id = Secure.getString(getApplicationContext().getContentResolver(), Secure.ANDROID_ID);
                if (KEY_CON.equalsIgnoreCase("Wifi")) {
                    if (ipAddress.contains("10.20.")) {
                        URL = "http://10.20.2.14/personal/index.php?serial=" + Build.SERIAL + "&device=" + android_id;
                    } else {
                        URL = "http://36.67.40.162:9024/personal/index.php?serial=" + Build.SERIAL + "&device=" + android_id;
                    }
                } else {
                    URL = "http://36.67.40.162:9024/personal/index.php?serial=" + Build.SERIAL + "&device=" + android_id;
                }
                webView.loadUrl(URL);
            } else if (response.contains("failed")) {
                try {
                    postDataToken();
                } catch (Exception e) {
                    toastMessage("Can't generate token");
                }
            } else {
                toastMessage("ELSE");
            }
    }
}

and this resulting Unfortunately App has stopped and the error logcat look like this:

any idea? I'm new to android and sometimes the app runs okay (after multiple error like this), but when I clear the data/uninstalled, mostly resulting to this E/installd: system dir 0 : /system/app/ and sometimes E/FirebaseInstanceId: Token retrieval failed: SERVICE_NOT_AVAILABLE because I'm using firebase when generating new token. I already set generate the token only if device is connected to internet.

this line ` Log.d("responsejson", response);` is a problem. your response in null — prashant17, Aug 06 '18 at 06:26
the response from server is a string "sukses" (success). it is not null — pdiani, Aug 06 '18 at 06:31
Your error logs clearly say your response is null and that's why there is a crash. as `Log.d` requires non-null message — prashant17, Aug 06 '18 at 06:34

yes did that, that's the log result. I always filter the log with show only selected application. or should I unchecked the regex? — pdiani, Aug 06 '18 at 07:26

    // Rest of the method
}

As per the native print method for printing the message in Android, your message object should be non null value.

In your case, response object is null. so add null check before printing message

if(null != response)
{
    Log.d("responsejson", response);
}

If you want to still print what is the value of response object even though it is null. Try to use below line.

Log.d("responsejson", "Response is "+response);

@pdiani, did you try adding the null check where ever you are printing response object. – Ram kiran Pachigolla Aug 06 '18 at 06:46
the log for the response is 08-06 14:58:02.148 24770-24770/? D/responsejson: Response is sukses. But still app has stopped. I already tried not to log the response object but doesn't work. – pdiani Aug 06 '18 at 06:59
@pdiani, you check the stack trace again and point out where exactly your app is crashing. – Ram kiran Pachigolla Aug 06 '18 at 07:03
edited the log, the error repeatedly showing D/PackageManager: remove MCS_UNBIND message and Posting MCS_UNBIND 10 secs later E/installd: system dir 0 : /system/app/ over and over – pdiani Aug 06 '18 at 07:20
Unless `req.prepare` can return null, then this isn't the problem – OneCricketeer Aug 06 '18 at 07:24

unfortunately app has stopped and resulting E/installd: system dir 0 : /system/app/
