Did you meant "Add device" ?

In case you did, its java.lang.NullPointerException in DeviceSettingsFragment.java line 77. Same thing will happen when you click on device name to change its settings.

Android 4.4.4
0.5.21

EDIT: Nutomic, after such crashes, shall I send report to Google with system info attached? Will it get to you? Or shall I write info from report here when creating/adding info to issue?

@chucic : both will reach him, but the github issue tracker is preferred I think.
Could you post a log? It works on my device.
Also, is it installed through the play store or f-droid?

Through Google Play.
Which log do you mean? My phone is not rooted, so I can't get to normal log file. Or do you mean logcat? Last time I did logcat, I end up with 2k+ lines file... But preview of report to google contains system log, event log and stack trace which starts with java.lang.RuntimeException: Unable ... : java.lang.NullPointerException at ... (30 more lines), so I think its relevant. But seems I'm not able copy+paste from preview, so I sent report.

I have the same problem. Can't add devices. App promtly crashes, when trying it. Former versions worked without problems.

Here's the logcat:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.nutomic.syncthingandroid/com.nutomic.syncthingandroid.activities.SettingsActivity}: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.preference.Preference.setOnPreferenceChangeListener(android.preference.Preference$OnPreferenceChangeListener)' on a null object reference

However, I don't understand this at all. The crash shouldn't occur in the first place, because the code is correct (and hasn't changed in weeks. Also, it seems I got the crash once, but then never again.

I'm seriously stumped on this one.
