While doing the same old job again, hunting Android.jar, I tried to find it in the platforms directory, but the directory was empty.. Anyone has explanation or knows another location where I can find this fox called android.jar?
You should have this directory: Android\Platforms
And there you should find the directories for the different Android versions you have loaded, like android-8, android-23 etc.
The android.jar file is in these directories.
Dear all,
Thanks and all of your advices were relevant and on the point.
The problem is now solved and the cause of it was, because I installed [Android SDK], but after the installation I forgot to
run the [SDK-Manager] and install the [API levels]..
Now another problem.. I can't see the [additional libraries] folder.
I suppose that you are speaking of the B4A Additional libraries folder.
You must create one somewhere and copy all the *.xml and *.jar files of the additional libraries there.
In the IDE menu Tools/Configure Paths you must enter thid folder.
Details in chapter 15.6.2 Additional libraries folder in the Beginner's Guide.
