I have an app that allows users to download an updated apk. Once downloaded, the new apk is installed. What I expected was:
- the installation dialog opens asking the user if they want to install, etc.
- the installation completes and asks the user if they want to open the app.
Instead, after the first step the dialog disappears/closes. If I relaunch the app manually I can see that the version has updated successfully and the app works as expected. The downloaded update is being directed to cordova.file.externalDataDirectory so there shouldn't be a problem with permissions. The only other thing I can think of is that the app has the application attribute android:launchMode="singleTask" which was included to prevent a user from launching another instance of the app (a necessary functionality).
Might the problem be the 'launchMode' attribute? If so, is there a work around?
[ADDITIONAL INFO] My symptoms are identical to this question. I haven't yet had success with the proposed solution.
[SOLVED] This answer is 'launchMode' is not a factor, the download directory is. The explanation is here.
