Why won't my packaged games work on Android anymore after having worked prior?

I installed 3 games on a galaxy s II. 2 of them work for approximately 2 days, when I installed the 3rd, and don’t work anymore.
Now, even if I unistall all and install again they don’t work anymore, neither. When click the logo to open, a black screen blinks and the aplication closes in sequence.

These games are Tap Chicken and 2 other that I’m doing.
Now I tried to install the Swing Ninja. It didn’t work too.

I’m packaging using “Development” configs.

Hello Pedro,

With a new version of the Engine comes new fixes and it is possible that this issue has changed or may no longer occur. Due to timetable of when this issue was first posted, we are marking this post as resolved for tracking purposes. If you are still experiencing the issue you reported in the current engine version, then please respond to this message with additional information and we will investigate as soon as possible. If you are experiencing a similar, but different issue at this time, could you please submit a new report for it.

Thank you.

Hi Rudy,
Man of us are having this same issue. Tappy chicken is the only game that works on my device. When I make edits to it they don’t even show up in the packaged version. Any of the project I make don’t work on my device. Is there some special touch epic is using? This has been an issue for quite sometime now. Any word?

Hello. I had this problem when I had updated java version. So I reinstall java, using the versin which comes with the engine and apparently the problem is gone.

Hello Kronos623,

I have a few questions for you that will help narrow down the issue that you are experiencing.

  1. Could you walk me through the steps you are using to add the games to your device?
  2. Did you make any updates or changes to the projects or to the device is the two days before the projects stopped working?
  3. Are you receiving any errors?
