Here is my code:

public class MainActivity extends AppCompatActivity {

    private Button upload;
    private static final String ACCESS_TOKEN = "<ACCESS_TOKEN>";
    //DbxRequestConfig config = new DbxRequestConfig("dropbox/java-tutorial");
    DbxRequestConfig config = DbxRequestConfig.newBuilder("dropbox/java-tutorial")
            .withHttpRequestor(OkHttp3Requestor.INSTANCE)
            .build();
    DbxClientV2 client = new DbxClientV2(config, ACCESS_TOKEN);
    private String outputFile = null;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        ActivityCompat.requestPermissions(MainActivity.this, new String[] {android.Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        upload = (Button)findViewById(R.id.button);
        upload.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {


             

                File patternDirectory = new File(Environment.getExternalStorageDirectory().getAbsolutePath().toString()+"/test.txt");
                patternDirectory.mkdirs();
                String filename = "test.txt";
                outputFile = Environment.getExternalStorageDirectory() + "/test.txt";
                String string = "Hello world!";
                FileOutputStream outputStream;

                try {
                    outputStream = new FileOutputStream(new File(patternDirectory.getAbsolutePath().toString()+"/test.txt"),true);
                    outputStream.write(string.getBytes());
                    outputStream.close();
                } catch (Exception e) {
                    System.out.println("Creating file not working");
                    e.printStackTrace();
                }



                try {
                    InputStream in = new FileInputStream(patternDirectory.getAbsolutePath().toString()+"/test.txt");
                    FileMetadata metadata = client.files().uploadBuilder("/test.txt").uploadAndFinish(in);

                } catch (Exception e) {
                    System.out.println("Upload file not working");
                    e.printStackTrace();
                }
            }
        });
    }

}

Do you have android.permission.INTERNET set for your app?

[kestites]

I don't think so.. how would I do that?

You can find information on that here:

Okay I did that, but now I am getting this error:

[Greg-DB · Accepted solution]

This error indicates that your OAuth 2 access token is incorrect, i.e., it doesn't match the expected pattern.

In the code you shared in your first post in this thread, you have your access token being saved to the variable ACCESS_TOKEN. It appears you redacted the value as "<ACCESS_TOKEN>" for the sake of posting it here, but make sure that the actual access token in your real code is valid, e.g., that you don't have any stray whitespace, etc.
