Answer 1

This code won't work on Nougat or later

It is possible to trigger the recent apps activity.

The StatusBarManagerService implements an public method which you can use through reflection.

You can use the following code:

Class serviceManagerClass = Class.forName("android.os.ServiceManager");
Method getService = serviceManagerClass.getMethod("getService", String.class);
IBinder retbinder = (IBinder) getService.invoke(serviceManagerClass, "statusbar");
Class statusBarClass = Class.forName(retbinder.getInterfaceDescriptor());
Object statusBarObject = statusBarClass.getClasses()[0].getMethod("asInterface", IBinder.class).invoke(null, new Object[] { retbinder });
Method clearAll = statusBarClass.getMethod("toggleRecentApps");
clearAll.setAccessible(true);
clearAll.invoke(statusBarObject);
