Can not open app built by v7.1.3

[CS-Tao]

My app was built successfully by Travis-ci, but it flash back unexpectedly when launch.
It works yesterday when built with v7.1.2. Does anybody know what caused this?

I have tried to upgrade build-tools version from 26.0.2 to 28.0.3, but it still can not work.

Files:

• config.xml
• package.json
• .travis.yml

Hi @CS-Tao, help me reproduce this please:
Can I just check out the develop branch of your app at https://github.com/CS-Tao/whu-library-seat-mobile/tree/develop and then install with cordova-android 7.1.2 to get a working app and then change to 7.1.3 to see that it does not work any more?

[CS-Tao]

@janpio Yes, please. Many thanks!

[janpio]

I have tried to upgrade build-tools version from 26.0.2 to 28.0.3, but it still can not work.

Why do you think this could be related and help?

@CS-Tao What exactly do you mean by "flash back unexpectedly"?

[CS-Tao]

@janpio I'm not sure. And just have a try, because I found that build-tools version has been changed in ".travis.yml" of this repo in v7.1.3.

[CS-Tao]

@CS-Tao What exactly do you mean by "flash back unexpectedly"?

Just I can't open my app, it exited when I try to open it.

[janpio]

Ok, I could reproduce your problem:

• 7.1.3: "Unfortunately, whu-library-seat-mobile has stopped."
• 7.1.2: starts, but then crashes because no index.html in www.

How can I build the actual web app in www so I can confirm that 7.1.2 really works?

Update: node build/build.js seems to do the trick. Waiting for it to finish now.

[janpio]

Ok, I can confirm that your app built with 7.1.2 works and intended, but crashes on startup with "Unfortunately, whu-library-seat-mobile has stopped." when built with 7.1.3. This looks like a bug to me - we will investigate.

run yarn build before yarn release:android like scripts in .travis.yml

[janpio]

I am using npm locally, but executing node build/build.js built a www that could be shown on the device.

[janpio]

Just to make sure this is not a general problem:
A new project created with cordova create and then cordova platform add [email protected] can be built and started just fine - so this is not a general problem of cordova-android 7.1.3 but something with your app (setup, plugins, ...). We will continue to investigate.

[CS-Tao]

Okay. Thank you~

I used adb logcat (h/t @oliversalzburg) to monitor the log output of the device, got this on app start:

Removing the plugin fixed the crash.

You were using a beta version of this plugin anyway:
cordova-plugin-local-notification 0.9.0-beta.2 "LocalNotification"
Try upgrading to the available beta3 or downgrade to an older, stable version.

If upgrading to beta does not help, please report the problem at the plugin's repository issues, I didn't see an existing one on a first look.

[janpio]

If using the newer version of the plugin doesn't work, please also report back here - maybe this is indeed caused by 7.1.3. Someone else from the team will look into this then.

[janpio]

Further investigation showed that this is indeed a problem of cordov-androida. The plugin files are copied to different places in 7.1.3 than they were in 7.1.2, which causes the plugin to crash. In your case it was cordova-plugin-local-notifications, but it could theoretically affect lots of other plugins as well.

We will continue investigating and provide a fix asap. Until then: Best stay with 7.1.2 @CS-Tao .

Closing in favour of #571 as it contains the key problem. But thanks for reporting and being so cooperative!

[brodycj]

#571 is now fixed in master. Will be fixed in nightly build and upcoming patch release, details in #571 (comment).

[brodycj]

7.1.4 patch release is now published to resolve the issue.
