v2 API

Hi Chuck,

I have a doubt.

Till now, I have always sent you the "Module: app" build.gradle file.

Attached, please, you may fing the "Project: PrvDef" one.

Is this correct? Thanks, in advance.

Kind Regards,

Andre

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
        

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Andre_LB,

Let's take a step back here. At this point, I think it's best to just get the Android example app from the Java SDK repository running. I want to make sure we're both on the same page there. PrvDef is your custom application, correct? For the moment, I think we should hold off on that.

Can you please verify that we're currently working with a cleanly checked out copy of the Android example app that has been imported into Android studio?

If not, let's start over with that and try to get it up and running.

Thanks,

Hi Chuck,

I downloaded the DropBox-SDK, executed "Import Project" in Android Studio and selected the folder:
..\examples\android

Since I have got the following error:-

Error:Failed to resolve: com.dropbox.core:dropbox-core-sdk:0-SNAPSHOT

I changed in the build.gradle file (Module: Android):-

compile group: 'com.dropbox.core', name: 'dropbox-core-sdk', version: '0-SNAPSHOT', changing: true

into:-

compile 'com.dropbox.core:dropbox-core-sdk:3.0.6'

Then, in my developer app console, I created the app "UserActivity" and updated the app key in AndroidManifest file and res/strings file.

Very well: now I am able to Authenticate and download a file.

Tomorrow I am going to check the differences between your example and my app (I confirm PrvDef is my custom application).

Thank you very much for your kind help and effort.

Kind Regards,

Andre

Andre_LB,

Thanks for the update and I'm glad the steps presented here before have allowed you to get the example app working. I think you're taking the right next steps by comparing between the two (example, and your app) and finding what differences might be causing the issue.

We'll still be here if you need help with anything Dropbox specific, but it sounds like you're on a good path to getting things resolved.

Thanks!

Hi Chuck,

thank you very much for your support: now my app is able to download and upload a file in my DropBox repository.

For being honest, I am not sure why before it did not work.

I tried to understand, but I would not be able, at the moment, to say why.

It is not important for me, but if it is for you, please, let me know and I could try to investigate.

At the moment, I am working in understanding how obtain FileMetadata information of a file.

Indeed I obtained the file revision of the downloaded one, by your example.

In other words, if I had not had from your example this information I would not be able to obtain it.

I tried to see in DropBox documentation, but I was not able to see anything.

mDbxClient.files().download(metadata.getPathLower(), metadata.getRev())
        .download(outputStream);

That is, the .files().download() method needs the file path and revision. In the code it is obtained by metadata.

So, the kind question is: let us suppose to know the DropBox folder and file name.

How may I obtain its own FileMetadata metadata information?

Thank you very much, again.

Kind Regards,

Andrea

If you know the path to the file, you can get the file metadata using `files().getMetadata()`:

https://dropbox.github.io/dropbox-sdk-java/api-docs/v3.0.x/com/dropbox/core/v2/files/DbxUserFilesRequests.html#getMetadata-java.lang.String-

By the way, if you just want to download the latest version of the file, you don't need to supply the 'rev' too. There's a version of the `files().download()` method that requires just the 'path' and not the 'rev':

https://dropbox.github.io/dropbox-sdk-java/api-docs/v3.0.x/com/dropbox/core/v2/files/DbxUserFilesRequests.html#download-java.lang.String-

Hi Greg,

yes, I have just tied and it works.

@ Greg, Chuck: thank you very much for your help.

     Now I may do, with API v2, what I need.

Kind Regards,

Andrea
