Smart home control demo could crash easily #11

Closed qiuzhong closed 7 years ago

qiuzhong commented 8 years ago

The OCF client smart-home-control v0.7.0 is built on cordova-plugin-ocf v0.6.2. It could crash easily when interacting with the OCF server side. It's not inevitable, but it's quite often to occur.

Steps

(Can't grantee to reproduce it 100%):

  1. Launch some OCF servers to create some resources(Like Buzzer, RGB LED)
  2. Launch the smart-home-control client, open "Continuous discovery" in settings, it will discover the resources
  3. Interact with the OCF resources

The attchment is part of the crash dump. smart-home-control-crashes.txt

Device:

Nexus5 Android 5.0.1 Intel Edison board flashed with Ostro image#510 (iotivity-1.1.1) SmartHome-Demo#c32b699

siovene commented 7 years ago

Can you try 0.8.0, just released? I have actually seen a crash on it too, to be honest, but the cause might be different and it looks far more stable in general.

qiuzhong commented 7 years ago

This release seems not stable either. I launched 3 OCF servers (Ostro image 519 with iotivity-node 1.1.1-3) and started this release app, it didn't last long (less than 2 minutes) even in the idle state. In the adb logcat, here is part of the crash log:

Any chance to get this fixed for Android 6.x? Thanks :)

siovene commented 7 years ago

I'll look into it.

qiuzhong commented 7 years ago

I googled the crash error information

java.lang.UnsatisfiedLinkError: dlopen failed: library "./obj/local/armeabi-v7a/liboc.so" not found

and found a post to explain this crash. https://code.google.com/p/android/issues/detail?id=175589

According to the explanation, it's about the android-targetSdkVersion configuration. My temporary workaround is to downgrade the android-targetSdkVersion to 22 in config.xml.

It works for me. The rebuilt app didn't crash when I turned the "Continuous discovery" swicth on.

siovene commented 7 years ago

v0.8.1 fixes the dlopen issue for Android 6+ but keeping the bug open because of the memory related crash that this issue originally reported.

ghost commented 7 years ago

Version 0.8.1 is behaving better in that it will launch and sensor discovery is functional for a short little while before the app crashes. I installed version 0.8.1 on an Android 5.1.1 tablet. Using this version I can't control sensor devices using the app.

siovene commented 7 years ago

Just a quick update to let you know that I found the cause of the crash. It's a bit tricky to fix but I think I can do it.

ghost commented 7 years ago

That's good news. Looking forward to trying the new version tomorrow.

qiuzhong commented 7 years ago

@uhofemei, some sensors like buzzer and rgb led may not work (see issues/12 and issue#13) But I tried two sensors (led and fan) on a Nexus 9 tablet (Android 5.1.1), and it worked well for v0.8.1.
