              devicePolicyManager.setPasswordQuality(demoDeviceAdmin,DevicePolicyManager.PASSWORD_QUALITY_UNSPECIFIED); 
              devicePolicyManager.setPasswordMinimumLength(demoDeviceAdmin, 0); 
              boolean resulttwo = devicePolicyManager.resetPassword("", DevicePolicyManager.RESET_PASSWORD_REQUIRE_ENTRY); 
              Log.d("Admin", "Disabling Password : " + resulttwo);

Answer 1

토스트가 취소 방법을 제공하는 디스플레이 지연을 극복하기 위해 데이터 멤버 및 null로 초기화

CountDownTimer timer = new CountDownTimer(20000, 1000) { 
     @Override 
     public void onTick(long millisUntilFinished) { 
      if (mToast != null) { 
       mToast.cancel(); 
      } 
      mToast = Toast.makeText(getApplicationContext(), "Disabling Password, Please wait : " + millisUntilFinished/1000, Toast.LENGTH_SHORT); 
      mToast.show(); 
      Log.d("Admin", "Disabling Password, Please wait : " + millisUntilFinished/1000); 
     } 

     @Override 
     public void onFinish() { 
      Log.d("Admin", "Disabling Password"); 
      devicePolicyManager.setPasswordQuality(demoDeviceAdmin,DevicePolicyManager.PASSWORD_QUALITY_UNSPECIFIED); 
      devicePolicyManager.setPasswordMinimumLength(demoDeviceAdmin, 0); 
      boolean resulttwo = devicePolicyManager.resetPassword("", DevicePolicyManager.RESET_PASSWORD_REQUIRE_ENTRY); 
      Log.d("Admin", "Disabling Password : "); 
      if (mToast != null) { 
       mToast.cancel(); 
      } 
      mToast = Toast.makeText(getApplicationContext(), "Congratulations!! Password Disabled", Toast.LENGTH_SHORT); 
      mToast.show(); 
     } 
    }.start();
