excuse me for the late answer...
@Handoko - you wrote:
Your apk is non-standard so it can't be installed.
Well I'm not sure if this is the point. What I did is I used the instruction from
here . After the apk was ready I opened it on my mobile but couldn't get it installed without saying any reason. And yes - all settings like
stay awake [checked!]
usb debugging [checked!]
verify apps via usb [checked!]
have been made
During the setup process for Lazarus I installed the build-tools for 26.0.3. Because my mobile runs on Android 6 I installed the build-tools for 23.0.3. as well. Don't know whether this was necessary or not, no idea what I should use for building an AVD with the avdmanager in order to test it inside the emulator either
So for me it comes back to point that I don't understand how all these different version of sdk, ndk, build-tools, api level... work together.
To test the apk file you wrote
the attachable file size must be <= 250 kb
Mine is 264kb. I will send it to you via PM
