I am making a camera app that takes an image when the camera is first initiated, I have got it working, however the only problem I am getting is that when a picture is taken, it stores the first image in the folder. EG. I install the app, the camera takes a photo, then the next time the camera takes another photo, it is the same as the first one. I have tried to make the data = null after, however this is still not working.
Any suggestions?

Android version 12 camera and gallery not working solution
I have successfully built a python server which even works but when java from android studio tries to connect to it fails with whole bunch of errors. I have understood that it fails while creating a new socket object but why that I don't know.
This is Java client, see at the end of the code particularly for the issue where I have created new Socket object:

This is my python server code:

print("Socket successfully created")
try:
port = 24224
s.bind(("", port))
print("socket binded to %s" %(port))
except socket.error as err:
print('Bind failed. Error Code : ' .format(err))
s.listen(10)
while True:
conn, addr = s.accept()
print('Got connection from', addr)
message = conn.recv(1024)
print("Client : " + message)
conn.close()

Looking at the stack trace I see that you are trying to connect on the ui thread which
is causing the crash. You need to move the connection logic in to its own thread

I am working on a project where user can upload a document to my server. This file can be selected either from local storage or a cloud storage ,say google drive. When i click on the file from file chooser all i am receiving is an account info and doc info as a uri, When i tried to fetch doc from this URI it is showing FileNotFound . I have gone through Drive API also but It is a bit confusing to me. Following are the points i came accross while trying Google Drive API:
1. How to select file from local storage.
2. How do I get FileId form the selected file.
I tried with the following code snippet:
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.setType("**/");
startActivityForResult(intent, 1000);
and In onActivityResult
#Override
public void onActivityResult(int requestCode, int resultCode,
Intent resultData) {
// The ACTION_OPEN_DOCUMENT intent was sent with the request code
// READ_REQUEST_CODE. If the request code seen here doesn't match, it's the
// response to some other intent, and the code below shouldn't run at all.
if (requestCode == 1000 && resultCode == Activity.RESULT_OK) {
// The document selected by the user won't be returned in the intent.
// Instead, a URI to that document will be contained in the return intent
// provided to this method as a parameter.
// Pull that URI using resultData.getData().
Uri uri = null;
if (resultData != null) {
uri = resultData.getData();
Log.i("URI", "Uri: " + uri.toString());
try {
readTextFromUri(uri);
getMimeType(this,uri);
} catch (IOException e) {
e.printStackTrace();
}
// showImage(uri);
}
}
}
private String readTextFromUri(Uri uri) throws IOException {
// FileInputStream fileInputStream=new FileInputStream(uri.)
InputStream inputStream = getContentResolver().openInputStream(uri);
BufferedReader reader = new BufferedReader(new InputStreamReader(
inputStream));
StringBuilder stringBuilder = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
stringBuilder.append(line);
}
// fileInputStream.close();
// parcelFileDescriptor.close();
return stringBuilder.toString();
}
Conclusion:
Can anyone please send me a link how to upload a document(I should even check the extension of the document) from both local storage and Google drive in a File chooser.

I am new to Java and I want to know how to invert audio (fixed voice inversion) coming from the input through a loopback to the output after a delay. How and where would I do this, and would I be able to set a frequency of the inversion somehow. Thanks.
