I would like to clarify what could be a mistake that prevents the launch of one of the activations.
mStart = (Button) findViewById(R.id.mStart); mStart.setText("Continue"); mStart.setOnClickListener(new View.OnClickListener(){ @Override public void onClick(View v) { Intent intent = new Intent(MainActivity.this, tesrclass.class); startActivity(intent); } }); The main activation starts, the bar opens, after a while the button hides and appears, after clicking on which the transition should be made, but simply throws it out.
