Android Question App install error

[gerredtor]

Hi, we have a user who gets the error code 103 during installing our app "lulaj 1" (he was installing an update out of the playstore). This happend with a samsung galaxy s3 mini with Android 4.1. I also tried it on an Emulator and there happened the same. On all other Systems it seems to work fine.

Which version of Java JDK are you using? And minSdkVersion - targetSdkVersion in the file Manifest?

 

[gerredtor]

My java jdk is jdk1.8.0_73, the minSdkVersion is 5 and the targetSdkVersion is 14

We have another app running (hypnose power) with same structure, everything is installing and running well here. I compared the codes, no difference, even in manifest.

Probably there is something wrong on users' device.

Try to suggest them these steps:

Have you tried to upload a new build to Google Play?

Were you able to solve this?

I have the same problem:
One person cannot install my app from Google Play. After downloading he gets the 103 Error. He has a Galaxy S3 Mini with 4.1.2.
He tried to go through all the troubleshooting you find by googling (remove/reactivate google account, factory reset, etc.) without success.

I also found this on Stackoverflow: http://stackoverflow.com/questions/33149140/play-store-cant-install-app-error-code-103

Older Android devices are unable to recognize SHA256 hash funcitons. Adding:

-sigalg SHA1withRSA -digestalg SHA1

as parameters to jarsigner should solve the issue even when using JDK 1.8.

I have to use an existing and non-b4a-compatible keystore, so i produced an unsigned apk with b4a and then signed it with jarsigner. Could someone please give me an example of a complete jarsigner commandline including the above suggestion from stackoverflow, so i can test it? Thanks!

Any other comments/suggestions/solutions to this issues are welcome as well of course!
