How to check if an activity is locked (app pinning) in android Lollipop

问题

I would like to know whether an activity is locked under app pinning in android 5.0 and above programatically. Please help me in this!

Thanks!

Method to get if the activity in lock task mode.
activityManager.isInLockTaskMode() API is deprecated in API level 23. Use the method activityManager.getLockTaskModeState() http://developer.android.com/reference/android/app/ActivityManager.html#getLockTaskModeState()

public boolean isAppInLockTaskMode() {
    ActivityManager activityManager;

    activityManager = (ActivityManager)
        this.getSystemService(Context.ACTIVITY_SERVICE);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        // For SDK version 23 and above.
        return activityManager.getLockTaskModeState()
            != ActivityManager.LOCK_TASK_MODE_NONE; 
    }

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        // When SDK version >= 21. This API is deprecated in 23.
        return activityManager.isInLockTaskMode();
    }

    return false;
}

Hope this helps you!
