For higher frequencies from about 20hz, the individual vibrations are no longer recognized which causes the creation of frequency side bands. Following is a Tone Generator based solution that appears stable, using an ontouch listener in a DialogFragment. For low modulation frequencies, this creates a tremolo effect.

A PackageInstaller class was added in Android 5.0, but it seemed complicated, so a lot of developers stuck with the earlier Intent-based. This process evolved over the years, such as adding ACTIONINSTALLPACKAGE in Android 4.0 and adding content Uri support in Android 7.0. Modulation means, that the amplitude of carrier wave is changed dynamically by a modulator wave. Pass that to startActivity(), and Android would take over from there.
