What's the error message?, check the logs in the IDE.

Also, try uninstalling the app before you compile in Release mode.

No errors? even the Unfiltered logs?

Now what do you mean by "i try to install the apk from the external sd card", compiling will install the app directly to the device if you have it connected via USB or bridge.

it start the installation it ask me to press install (shows that the program send sms and communicate with internet)
I press the install

You may have to uninstall the old app (not the old B4A) on the device if it was compiled before B4A 6.30. Take a look at this link:
https://www.b4x.com/android/forum/threads/b4a-v6-30-has-been-released.71212/
from its first post Erel says:
Note that the debug key has been replaced. If you are using B4A-Bridge then you will need to uninstall the existing developed app before deploying the new one (required once).

The reason the program installed for you now is because you created a new app by changing the package name. As I explained to you in post#6, you needed to UNinstall the old app on the phone/tablet, and then install the app compiled with the newer version of B4A. Actually your old app is still in the phone/tablet

Have you set the targetSdkVersion to 23+ ?
