如何分析是那个应用导致状态栏消失

如何分析是那个应用导致状态栏消失

状态栏主要的几个控制类中需要增加log如下,再根据pid去查是那个进程.

StatusBarManager.java

public void disable(int what) {
        try {
            final IStatusBarService svc = getService();
            if (svc != null) {
            if ( (what & DISABLE_EXPAND) != 0 ) {
            Slog.d("StatusBarManager", "disable status bar , call from" , new RuntimeException("disable"));
            }
                svc.disable(what, mToken, mContext.getPackageName());
            }
        } catch (RemoteException ex) {
            // system process is dead anyway.
            throw new RuntimeException(ex);
        }
    }

StatusBarManagerService.java

private void disableLocked(int userId, int what, IBinder token, String pkg) {
        // It's important that the the callback and the call to mBar get done
        // in the same order when multiple threads are calling this function
        // so they are paired correctly.  The messages on the handler will be
        // handled in the order they were enqueued, but will be outside the lock.
        manageDisableListLocked(userId, what, token, pkg);
        // Ensure state for the current user is applied, even if passed a non-current user.
        final int net = gatherDisableActionsLocked(mCurrentUserId);
        if (net != mDisabled) {
            mDisabled = net;
            mHandler.post(new Runnable() {
                    public void run() {
                        mNotificationDelegate.onSetDisabled(net);
                    }
                });
            if (mBar != null) {
                try {
                    /// M:[ALPS01673960] Fix User cannot drag down the notification bar.
                    Slog.d(TAG, "disable statusbar calling PID = " + Binder.getCallingPid());
                    mBar.disable(net);
                } catch (RemoteException ex) {
                }
            }
        }
    }
