Steps toward following all the inconvenient, changing android rules:

Browse Source 
* Set android:debuggable=false.
 * Call native code through JNI only.  Having a native executable on disk and exec-ing it no longer seems possible.
 * Do all the Tilde Friends things in one process, without a proper sandbox, until I can wire up a restricted service worker process.
 * Jam Android App Bundle (.aab) building into the makefile.
 * Yuck.
