Another Sliding up crash

[fluxxion82]

I'm using this library and it seems that sometimes when you slide the panel up, it will crash the app. Here is the logcat logs: 04-29 10:08:19.206: E/AndroidRuntime(8901): FATAL EXCEPTION: main 04-29

Hmm, seems like a crash in side of the Support library. What version of Android are you running?

[fluxxion82]

The crash seems to happen every single time on Android version 4.4.2. On another phone, running Android version 4.1.2, I don't get the crash.

Another phone that seems to get the crash is running Android 4.0.4

Is the crash occurring in the example project? Or your own app?

[fluxxion82]

It's in my own app, but it's based on the example.

If it doesn't crash in the example, I can't help you without seeing your layout file.

[tokudu]

Please reopen if the crash happens in the demo.

[staber]

@tokudu this can be reproduced in the demo by adding

mLayout.showPanel();

to the onPanelHidden listener. Then hide the panel from the Menu button. Example use case:

• Hide the panel when swiping a ViewPager in the Main View
• Inside the hidePanel listener, update the contents of the dragable view then show the panel again.

[tokudu]

The crash is inside of the support library, so there is not much I can do there. The work around is to run it on the handler

         mLayout.post(new Runnable() {
                    @Override
                    public void run() {
                        mLayout.showPanel();
                    }
                });

No problem. Just wanted to let you know it's present in the Demo too. Runnable works great. Thanks for the library.
