Get Google Drive Folder ResourceID

Question

Ich brauche die ResourceId eines Ordners in meinem Laufwerk erstellt. Geworben diesen docs first und second Ich tue dies:

private void CreateFolderOnGoogleDrive() { 
    Query query = new Query.Builder() 
      .addFilter(Filters.and(Filters.eq(
          SearchableField.TITLE, "Folder"), 
        Filters.eq(SearchableField.TRASHED, false))) 
      .build(); 
    Drive.DriveApi.query(mGoogleApiClient, query) 
      .setResultCallback(new ResultCallback<DriveApi.MetadataBufferResult>() { 
       @Override 
       public void onResult(DriveApi.MetadataBufferResult result) { 
        if (!result.getStatus().isSuccess()) { 
         System.out.println("Cannot create folder in the root."); 
        } else { 
         boolean isFound = false; 
         for (Metadata m : result.getMetadataBuffer()) { 
          if (m.getTitle().equals("Folder")) { 
           Toast.makeText(getApplicationContext(), "folder exist", Toast.LENGTH_LONG).show(); 
           isFound = true; 
           break; 
          } 
         } 
         if (!isFound) { 
          System.out.println("Folder not found; creating it."); 
          MetadataChangeSet changeSet = new MetadataChangeSet.Builder() 
            .setTitle("Folder") 
            .build(); 
          Drive.DriveApi.getRootFolder(mGoogleApiClient) 
            .createFolder(mGoogleApiClient, changeSet) 
            .setResultCallback(new ResultCallback<DriveFolder.DriveFolderResult>() { 
             @Override 
             public void onResult(DriveFolder.DriveFolderResult result) { 
              if (!result.getStatus().isSuccess()) { 
               System.out.println("Error while trying to create the folder"); 
              } else { 
               System.out.println("Created a folder"); 
}             
              } 
               System.out.println(result.getDriveFolder().getDriveId().getResourceId()); 
// ALWAYS return as null 

             }); 
          } 
         } 
        } 
       }); 

Mit diesem Code, ich bin jeden Wert innerhalb result mit Ausnahme des getResourceId bekommen() (die immer null ist, wenn ich es durch den Code zu bekommen).

Nun, ich kann sogar die ID meines Ordners in der Laufwerks-URL sehen.

Schon viel Forschung getan, aber keine von ihnen gibt noch eine Lösung. Sie geben nur GRÜNDE.

Gibt es jemanden, der das gelöst hat?

Als die Antwort von @seanpj um Google Drive Android Api Completion Event for Folder Creation, können Sie versuchen, wie unten, obwohl es vielleicht nicht eine sehr schöne Lösung für jetzt ist. Ich hoffe es hilft!

Innen <application> von AndroidManifest.xml:

<service android:name=".MyDriveEventService" android:exported="true"> 
    <intent-filter> 
     <action android:name="com.google.android.gms.drive.events.HANDLE_EVENT"/> 
    </intent-filter> 
</service> 

MyDriveEventService.java:

public class MyDriveEventService extends DriveEventService { 
    ... 
    @Override 
    public void onCompletion(CompletionEvent completionEvent) {    
     DriveId driveId = completionEvent.getDriveId(); 
     Log.d(TAG, "File ResourceId: " + driveId.getResourceId()); 
     DriveId folderDriveId = MainActivity.getParentID(driveId); 
     if (folderDriveId != null && folderDriveId.getResourceId() != null) 
      Log.d(TAG, "Folder ResourceId: " + folderDriveId.getResourceId()); 
    } 
} 

Innen MainActivity.java:

@Override 
public void onConnected(@Nullable Bundle bundle) { 
    MetadataChangeSet changeSet = new MetadataChangeSet.Builder() 
      .setTitle("NewFolder").build(); 
    Drive.DriveApi.getRootFolder(mGoogleApiClient).createFolder(
      mGoogleApiClient, changeSet).setResultCallback(folderCreatedCallback); 
} 

public static DriveId getParentID(DriveId driveId) { 
    MetadataBuffer mdb = null; 
    DriveApi.MetadataBufferResult mbRslt = driveId.asDriveResource().listParents(mGoogleApiClient).await(); 
    if (mbRslt.getStatus().isSuccess()) try { 
     mdb = mbRslt.getMetadataBuffer(); 
     if (mdb.getCount() > 0) 
      return mdb.get(0).getDriveId(); 
    } catch (Exception e) { e.printStackTrace();} 
    finally { 
     if (mdb != null) mdb.close(); 
    } 
    return null; 
} 

private final ResultCallback<DriveFolder.DriveFolderResult> folderCreatedCallback = new 
     ResultCallback<DriveFolder.DriveFolderResult>() { 
      @Override 
      public void onResult(DriveFolder.DriveFolderResult result) { 
       if (!result.getStatus().isSuccess()) { 
        Log.e(TAG, "Error while trying to create the folder"); 
        return; 
       } 

       Log.i(TAG, "Created a folder: " + result.getDriveFolder().getDriveId()); 
       Log.i(TAG, "Folder Resource Id: " + result.getDriveFolder().getDriveId().getResourceId()); // null 

       // Creating an empty file 
       MetadataChangeSet changeSet = new MetadataChangeSet.Builder() 
         .setTitle("New file") 
         .setMimeType("text/plain").build(); 
       result.getDriveFolder().createFile(mGoogleApiClient, changeSet, null /* DriveContents */, new ExecutionOptions.Builder() 
           .setNotifyOnCompletion(true) 
           .build()) 
         .setResultCallback(new ResultCallback<DriveFolder.DriveFileResult>() { 
          @Override 
          public void onResult(@NonNull DriveFolder.DriveFileResult driveFileResult) { 
          } 
         }); 

      } 
     };
