Hey everyone, As stated in the subject line, my Cordova app running on Android is experiencing issues with connecting to CB lite after the app has been put in background mode for a number of hours. This is happening to all of my Android users and me. When I look at the network log of the traffic …

@jamiltz , Background mode is triggered when the user leaves the app. This morning I added the following code: function onResume() { if (device.platform === 'Android') { cblite.getURL(function (error, url) { if (error) { console.log('CB Initilization error ' + JSON.stringify(…

I did a test with the Todo-lite example and the same issue is occurring when I return to the app after 30 minutes. This is a big problem as it renders CBL-based apps useless.

@jamiltz , Let me clarify “user leaves the app”, the app is background mode and is paused. If the app is shutdown and restarted, everything with CBL is fine. But there’s no way through code to do a full shutdown and restart with Cordova.

Hi @agillette , I have one request to verity. From your comment, once the app resumed, the app can obtain URL of CBL REST API endpoint. Can you try to access its URL from Android browser or to access from out-side of Android device/emulator by browser or curl command? If Http server can response, …

Hi @hideki , I’m pretty sure that the WebView is not the issue. On resume, cblite.getURL(function (error, url) is working. But if I make a REST call to my database, the calls are pending. I’m going to modify my to make a call to sync gateway on resume. If it responds and the REST call to the loc…

@hideki , I just ran a test where on resume my code is making two calls, one to the local db and one to sync gateway. The sync gateway responded with 200, where as the local db is still in “pending” state. This proves to me that the problem is with CBL and not the WebView.

@hideki : It could be that the OS has closed the TCP listener socket. (For comparison, iOS does this when an app has been backgrounded too long and/or the device locks.)

Hi @agillette , Thank you very much for sharing additional information. To track this issue, I created the ticket in github. https://github.com/couchbase/couchbase-lite-java-core/issues/1296 Thanks, Hideki

Thanks @hideki , Please keep me posted. I’m planning to submit my app into both Apple and Google app stores in two weeks.

@hideki,

There’s a code error in the test that I just did. I’ll have to try again tomorrow morning.
