Return a failure result in inKeyguardRestrictedInputMode() : <p>I have a function to determine four states of phone's screen: screen on, screen off, screen on with lock, screen on without lock. My function is</p>

<pre><code>private KeyguardManager keyguardManager;
public String getScreenStatus()
{
    String sreen_State="unknown";
    keyguardManager = (KeyguardManager) getSystemService(KEYGUARD_SERVICE);
    PowerManager pm = (PowerManager) getApplicationContext().getSystemService(Context.POWER_SERVICE);
    if (Build.VERSION.SDK_INT &gt;= Build.VERSION_CODES.KITKAT_WATCH) {
        if (pm.isInteractive()) {
            sreen_State="screen_on";
            if(!keyguardManager.inKeyguardRestrictedInputMode()) {
                sreen_State="screen_on_no_lock_screen";

            }else{
                Log.i(TAG, "screen_on_lock_screen");
                sreen_State="screen_on_lock_screen";
            }
        }
        else {
            sreen_State="screen_off";
        }
    }
    else if(Build.VERSION.SDK_INT &lt; Build.VERSION_CODES.KITKAT_WATCH){
        if(pm.isScreenOn()){
            sreen_State="screen_on";
            if(!keyguardManager.inKeyguardRestrictedInputMode()) {
                Log.i(TAG, "screen_on_no_lock_screen");
                sreen_State="screen_on_no_lock_screen";

            }else{
                Log.i(TAG, "screen_on_lock_screen");
                sreen_State="screen_on_lock_screen";
            }

        }
        else {
            mIsScreenOn=false;
            sreen_State="screen_off";
        }
    }
    return sreen_State;
}
</code></pre>

<p>The above function returns corrected states of the screen. However, it has error when I add one more code as follows:</p>

<pre><code> KeyguardManager.KeyguardLock
 kl = keyguardManager.newKeyguardLock("MyKeyguardLock");
 if(index.equals("1"))
        kl.disableKeyguard();
  else if(indexequals("2"))
        kl.reenableKeyguard();
  getScreenStatus();
</code></pre>

<p>The index can change by press a button. Now, the wrong state of screen is happen. It always return <code>screen_on_lock_screen</code>, although the screen is in <code>screen_on_no_lock_screen</code>. How could I fix my issue?</p>
