Code for inserting data into the database not working - java

I am storing a picture with some information in the database. I am taking an image. It is not inserting data, showing that int.java.lang.stringlength() invoke virtual method. It was working the last day but when I delete the history from Xammp database and then I run the code it shows the error.

How to save an image using CircleImageView Android Studio

I wrote a program where a user can click a TextView (editPhoto) and select an image (profile picture) and display on the profile and also save it on my database with the rest of the profile details, but as soon as I leave the page the picture disappears from the CircleImageView although it's still saved on my database. I am able to save the rest of the users information on the profile like name, username, email etc using .setText() so how can I do the same with the CircleImageView for the profile picture? Thanks in advance
CODE:
private TextView editPhoto;
CircleImageView profilePic;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_edit_profile);
profilePic = findViewById(R.id.profilepic);
editPhoto = findViewById(R.id.txtEditPP);
editPhoto.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
chooseFile();
}
});
}
private void chooseFile(){
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Choose Photo"),1);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1 && resultCode == RESULT_OK && data != null && data.getData() != null){
Uri filepath = data.getData();
try {
bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), filepath);
profilePic.setImageBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
UploadPicture(getId, getStringImage(bitmap));
}
}
//UPLOAD PROFILE PICTURE
private void UploadPicture(final String id, final String photo) {
StringRequest stringRequest = new StringRequest(Request.Method.POST, URL_UPLOAD, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.i(TAG, response.toString());
try {
JSONObject jsonObject = new JSONObject(response);
String success = jsonObject.getString("success");
if (success.equals("1")){
Toast.makeText(EditProfile.this, "Photo Uploaded", Toast.LENGTH_SHORT).show();
}
} catch (JSONException e) {
e.printStackTrace();
Toast.makeText(EditProfile.this, "Error Uploading Image!", Toast.LENGTH_SHORT).show();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(EditProfile.this, "Error Uploading Image!", Toast.LENGTH_SHORT).show();
}
})
{
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put("ID", id);
params.put("photo", photo);
return params;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(stringRequest);
}
public String getStringImage(Bitmap bitmap){
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, byteArrayOutputStream);
byte[] imageByteArr = byteArrayOutputStream.toByteArray();
String encodedImage = Base64.encodeToString(imageByteArr, Base64.DEFAULT);
return encodedImage;
}
In onResume can you reload imageView using bitmap object?
Also make bitmap object as class variable reloading image will work for you in this case.

How to store 2mb above file size of image to database via Volley?

I have a code for uploading images from mobile to my phpmyadmin database via Volley. I can successfully upload images when it is in small ".jpg" format and also, the sizes don't exceed 2mb. Now when I choose a picture (specifically from camera pictures) that's more than that, it doesn't prompt any error and doesn't also add the picture to the database. How can I solve this and how can I store?

Volley PUT image request

I am trying to make a volley PUT request to upload an image, Since httpEntity is deprecated now, I had to do some other research, I came across these solutions and tried to implement them into my code :
1. https://gist.github.com/anggadarkprince/a7c536da091f4b26bb4abf2f92926594
2. How to send multipart request using Volley without HttpEntity?
3. Working POST Multipart Request with Volley and without HttpEntity
but still I cannot upload my image. The image I want to upload is either captured from the camera or selected in the gallery, and it is executed onClick.

VolleyMultipartRequest.java and VolleySingleton.java I am using the same class as what my first link has.

BasicNetwork.performRequest: Unexpected response code 500 for https://my url
W/System.err: org.json.JSONException: No value for status
I am not sure what is causing my problem,please help, thank you!
Here is Simple Solution And Complete Example for Uploading File Using Volley Android
1) Gradle Import
compile 'dev.dworks.libs:volleyplus:+'
2)Now Create a Class RequestManager
public class RequestManager {
private static RequestManager mRequestManager;
/**
* Queue which Manages the Network Requests :-)
*/
private static RequestQueue mRequestQueue;
// ImageLoader Instance
private RequestManager() {
}
public static RequestManager get(Context context) {
if (mRequestManager == null)
mRequestManager = new RequestManager();
return mRequestManager;
}
/**
* #param context application context
*/
public static RequestQueue getnstance(Context context) {
if (mRequestQueue == null) {
mRequestQueue = Volley.newRequestQueue(context);
}
return mRequestQueue;
}
}
3)Now Create a Class to handle Request for uploading File WebService
public class WebService {
private RequestQueue mRequestQueue;
private static WebService apiRequests = null;
public static WebService getInstance() {
if (apiRequests == null) {
apiRequests = new WebService();
return apiRequests;
}
return apiRequests;
}
public void updateProfile(Context context, String doc_name, String doc_type, String appliance_id, File file, Response.Listener<String> listener, Response.ErrorListener errorListener) {
SimpleMultiPartRequest request = new SimpleMultiPartRequest(Request.Method.POST, "YOUR URL HERE", listener, errorListener);
// request.setParams(data);
mRequestQueue = RequestManager.getnstance(context);
request.addMultipartParam("token", "text", "tdfysghfhsdfh");
request.addMultipartParam("parameter_1", "text", doc_name);
request.addMultipartParam("dparameter_2", "text", doc_type);
request.addMultipartParam("parameter_3", "text", appliance_id);
request.addFile("document_file", file.getPath());
request.setFixedStreamingMode(true);
mRequestQueue.add(request);
}
}
4) And Now Call The method Like This to Hit the service
public class Main2Activity extends AppCompatActivity implements Response.ErrorListener, Response.Listener<String>{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
Button button=(Button)findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
uploadData();
}
});
}
private void uploadData() {
WebService.getInstance().updateProfile(getActivity(), "appl_doc", "appliance", "1", mChoosenFile, this, this);
}
#Override
public void onErrorResponse(VolleyError error) {
}
#Override
public void onResponse(String response) {
//Your response here
}
}
mChoosenFile is your image file
First of all convert your image bitmap to base64 string using the following code:
public String getStringImage(Bitmap bmp){
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] imageBytes = baos.toByteArray();
String encodedImage = Base64.encodeToString(imageBytes, Base64.DEFAULT);
return encodedImage;
}
Then make a PUT Request like the following one and pass the base64 string as a parameter of the request
url = "http://example.com";
StringRequest putRequest = new StringRequest(Request.Method.PUT, url,
new Response.Listener<String>()
{
#Override
public void onResponse(String response) {
// response
Log.d("Response", response);
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error) {
// error
Log.d("Error.Response", response);
}
}
) {
#Override
protected Map<String, String> getParams()
{
Map<String, String> params = new HashMap<String, String> ();
params.put("imageString", base64String);
return params;
}
};
queue.add(putRequest);
Refer Android Volley Tutorial if you face any difficulty in implementing volley request.

Thank you and help would be appreciated. For some reason the this is underlined in red. How do I resolve this?
Change the this in nested classes (such as in new Response.ErrorListener()) to:
Main6Activity.this
