NPE in LoginActivity (after upgrading to 0.3.0 from 0.2.0...?)

[sbose78]

On calling : ParticleDeviceSetupLibrary.startDeviceSetup(Activity.this);

Below is the stacktrace :

Updating the title: the permission referenced is from another app, but there is a real bug here in the form of an NPE.

Does the device where you're hitting this have a hardware keyboard by any chance...?

[sbose78]

No @jensck . It's an Android device without an external keyboard.

Please let me know what other details you would need.

[jensck]

What else can you tell me about this, e.g.:

• device make and model
• version of Android
• is this a custom ROM?
• which software keyboard it's using
• what are the steps to reproduce? Do those steps work on a fresh install?
• do you have developer options set like destroying activities as soon as you exit them?

[jensck]

Also, none of the code being referred to by that stack trace seems to have changed from 0.2.0 to 0.3.0 -- it seems odd that the upgrade would cause it. Can you try downgrading and see if you can still reproduce it?

[jensck]

Closing this; please feel free to re-open if you are still running into this issue and can provide some of the info above!
