Android app crashes when linking to another page
Every time I clicked on the button I created to go to the next Activity, the app crashes.
Here is the code I used:

this.startActivity ( intent );

Select Multiple Images and Display in Multiple ImageView

I want to select 4 images from phone gallery and display them in 4 imageviews, so far below code is working fine by selecting 4 buttons individually.
Now i want to implement to select 4 images with 1 button and get them displayed in 4 imageview simulatenously, i am stuck here and have done many google search and found a solution by using getClipData below but after many trial and error still not working, can someone enlighthen me and appreicate your help.
if(data.getClipData() != null) {
int count = data.getClipData().getItemCount(); //evaluate the count before the for loop --- otherwise, the count is evaluated every loop.
for(int i = 0; i < count; i++) {
// Uri filepath = data.getClipData().getItemAt(i).getUri();
}
//do something with the image (save it to some directory or whatever you need to do with it here)
}
} else if(data.getData() != null) {
String imagePath = data.getData().getPath();
//do something with the image (save it to some directory or whatever you need to do with it here)

You can do it in the following way . I have used viewBinding in this project and have used the new activity contracts for getting images since startActivity is deprecated .The code is as follows .
public class MainActivity extends AppCompatActivity {
//Getting the binding
ActivityMainBinding binding;
//Defining a contract and assiging it to imageView
ActivityResultLauncher<String> mGetMultipleContent = registerForActivityResult(new ActivityResultContracts.GetMultipleContents(),
new ActivityResultCallback<List<Uri>>() {
#Override
public void onActivityResult(List<Uri> result) {
for (int i = 0; i < result.size(); i++) {
binding.imgone.setImageURI(result.get(0));
binding.imgtwo.setImageURI(result.get(1));
binding.imgthree.setImageURI(result.get(2));
binding.imgfour.setImageURI(result.get(3));
}
}
});
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
binding = ActivityMainBinding.inflate(getLayoutInflater());
setContentView(binding.getRoot());
//Launching contract for getting images
binding.addButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mGetMultipleContent.launch("image/*");
}
});
}
}

How to build a URL in Koush ion

I am building an app to upload images to my company server
I am using koush-ion for the upload,
now my problem is I have to dynamically change the URL for upload depending on information entered in another activity(LoginActivity) via edittext boxes
and I don't understand how to do that
so what I want to happen is the client enters thier Email, password and clientID(4 digits)(in LoginActivity) and the app uses that to build a url for the upload
like this one(in CameraActivity)
https://www.blahpractice.co.za/files-upload-ruben.asp?MyForm=Yes&ClientID=1234&Username=man#blahpractice.co.za&Pwd=BlahBlah123#
I got this From the koush github, and i am unsure if this is what i am looking for and also how to implement data from another activity in koush-ion
Post application/x-www-form-urlencoded and read a String
Ion.with(getContext())
.load("https://koush.clockworkmod.com/test/echo")
.setBodyParameter("goop", "noop")
.setBodyParameter("foo", "bar")
.asString()
.setCallback(...)

You could store the url on the shared preferences and retrieve it every time you execute your upload task and set it on the .load() method.
Also, what you need to send an image to your server is a multipart post. I haven't used Ion but I have used multipart in other libraries like OkHttp, I´ve copied the method that appears on the Ion documentation:
String dynamicUrl = PreferenceManager.getDefaultSharedPreferences(context).getString(CURRENT_SELECTED_URL, null);
File myImage = new File(myImagePath);
if(dynamicUrl != null) {
Ion.with(getContext())
.load(dynamicUrl)
.uploadProgressBar(uploadProgressBar)
.setMultipartParameter("goop", "noop")
.setMultipartFile("myImageName", "image/*", myImage)
.asJsonObject()
.setCallback(...)
}

Mapping listView items with photos from the cloud

I have some places in a listView. These are picked from a Google Map, for which I would like to take a picture. One for each. These photos should be available online, so I have searched for some proper solutions. I've choosed imgur's API.
Is it possible to link pictures with places? I would like to make mapping between uploaded pictures and listView items.

Get the content of image view in android

In my app the user can laod an image from Gallery or from Camera and it be shown in
imageView. What i want to do is to send the image to my server. In order to that,
i should to convert it to Base64 type.
Everything is well but i don't know how to get the content of the imageView for converting it,
and where exactly to put the code.
My activity is :
public class MainActivity extends Activity {
private static int FROM_CAMERA = 1;
private static int FROM_GALLERY = 2;
ProgressDialog pDialog;
JSONParser jsonParser = new JSONParser();
EditText inputName;
EditText inputEmail;
Button sendData;
JSONObject json;
ImageView userImg;
private static String url_create_user = "http://localhost/android_connect/create_user.php";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
inputName = (EditText)findViewById(R.id.userName);
inputEmail = (EditText)findViewById(R.id.email);
sendData = (Button)findViewById(R.id.send);
userImg = (ImageView)findViewById(R.id.userImage);
sendData.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (isNetworkConnected())
new CreateNewUser().execute();
else
Toast.makeText(getApplicationContext(), "Please connect to internet!", Toast.LENGTH_LONG).show();
}
});
userImg.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String[] options = new String[]{"Camera","Gallery"};
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setItems(options, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
if(which == 0){
Intent c = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(c, FROM_CAMERA);
}
else{
Intent g = new Intent(Intent.ACTION_GET_CONTENT);
g.setType("image/*");
startActivityForResult(g, FROM_GALLERY);
}
}
});
builder.create();
builder.show();
}
});
}
class CreateNewUser extends AsyncTask<String, String,String> {
#Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(MainActivity.this);
pDialog.setMessage("Creating user...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
#Override
protected String doInBackground(String... arg0) {
String username = inputName.getText().toString();
String email = inputEmail.getText().toString();
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("username", username));
params.add(new BasicNameValuePair("email", email));
json = jsonParser.makeHttpRequest(url_create_user, "POST", params);
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
} else {
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
protected void onPostExecute(String file_url) {
// dismiss the dialog once done
pDialog.dismiss();
if(json != null){
Toast.makeText(getApplicationContext(), "The data has been sent successfully!", Toast.LENGTH_LONG).show();
}
else
Toast.makeText(getApplicationContext(), "Failed to send data!", Toast.LENGTH_LONG).show();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
ImageView imageView = (ImageView)findViewById(R.id.userImage);
if (requestCode == FROM_GALLERY && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
else{
if(requestCode == FROM_CAMERA && resultCode == RESULT_OK && null != data )
{
Bundle extras = data.getExtras();
Bitmap photo = extras.getParcelable("data");
imageView.setImageBitmap(photo);
}
}
}
private boolean isNetworkConnected() {
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo ni = cm.getActiveNetworkInfo();
if (ni == null) return false;
else return true;
}
}
This is the code for convert the image to base64:
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 90, stream);
byte [] byte_arr = stream.toByteArray();
String image_str = Base64.encodeToString(byte_arr, Base64.DEFAULT);
and i should add this sentence in doInBackground method:
params.add(new BasicNameValuePair("image", image_str));
Thanks!!!

This is how you get the bitmap of your Imageview:
Bitmap bitmap = ((BitmapDrawable)imageView.getDrawable()).getBitmap();
After you convert to base64.

I solved my problem. here is the solution:
To get the content of the image to bitmap i do this -
Bitmap bitmap = ((BitmapDrawable)userImg.getBackground()).getBitmap();
and this works very well without any errors.
I put the converting code in onActivityResult() like this:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == FROM_GALLERY && resultCode == RESULT_OK && null != data) {
//Getting the image from gallery and set it to imageView
}
else{
if(requestCode == FROM_CAMERA && resultCode == RESULT_OK && null != data )
{
//Getting the image from camera and set it to imageView
}
}
Bitmap bitmap = ((BitmapDrawable)userImg.getBackground()).getBitmap();
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte [] byte_arr = stream.toByteArray();
image = Base64.encodeToString(byte_arr, Base64.DEFAULT);
}
Everything get well.
