Dropbox sync API startLink() not working on HTC One (which has system installed Dropbox app on the device)

[Cross-linking for reference: https://stackoverflow.com/questions/30212974/dropbox-sync-api-startlink-not-working-on-htc-one-which-has-system-installed ]

Does this only happen on HTC One devices with the Dropbox app installed, or does it happen on any Android device with the Dropbox app installed? (If you haven't tried the latter, please do.)

Have you set up the db-{YOUR_APP_KEY} intent filter, per the instructions?

Can you post the relevant code you're using to set up the account manager and call startLink, per the tutorial?

Thank you Greg for the response but as mentioned in my post it works fine on all other Android devices (With and without Dropbox app) and is failing only on HTC ONE.

private DbxAccountManager mDbxAcctMgr;
    mDbxAcctMgr = DbxAccountManager.getInstance(
            mContext, Constants.DROPBOX_APP_KEY,
            Constants.DROPBOX_APP_SECRET);
    if (mDbxAcctMgr != null) {
        mDbxAcctMgr.startLink(activity,
                Constants.REQUEST_LINK_TO_DBX);
    }

Thanks! Have you set up the db-{YOUR_APP_KEY} intent filter, per the instructions? Can you post that too?

Yes and on all other devices I'm able to authorize and upload files to Dropbox.

    <activity android:name="com.dropbox.sync.android.DbxAuthActivity" />
    <activity
      android:name="com.dropbox.client2.android.AuthActivity"
      android:launchMode="singleTask" >
      <intent-filter>
        <data android:scheme="db-i12524brdnlzkb1" />
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.BROWSABLE" />
        <category android:name="android.intent.category.DEFAULT" />
      </intent-filter>
    </activity>
    <service
      android:name="com.dropbox.sync.android.DbxSyncService"
      android:enabled="true"
      android:exported="false"
      android:label="Dropbox Sync" />  

Thanks! That's helpful. We'll look into it.

Also, can you let me know the version number for the Dropbox app installed on the HTC Once device(s) you've seen this on?

Dropbox app version 2.3.5.10
Dropbox for HTC Sense version 6.0.766933

Version 2.3.5.10 of the Dropbox app is a bit old now. Can you update to the latest version (currently 2.5.0.4 on Google Play) and let me know if you still see the issue?
