點擊Launcher桌面上的圖標，會先有圖標放大的動畫，然後才進入應用。如何去掉動畫效果？ 請修改Launcher.java的startActivity方法，如下：

boolean startActivity(View v, Intent intent, Object tag) {
        if (LauncherLog.DEBUG) {
            LauncherLog.d(TAG, "startActivity v = " + v + ", intent = " + intent + ", tag = " + tag);
        }
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        try {
            // Only launch using the new animation if the shortcut has not opted out (this is a
            // private contract between launcher and may be ignored in the future).
            //boolean useLaunchAnimation = (v != null) && //mtk modify
            //        !intent.hasExtra(INTENT_EXTRA_IGNORE_LAUNCH_ANIMATION); //mtk modify
            boolean useLaunchAnimation = false; //mtk add
            /// M: add systrace to analyze application launche time.
            Trace.traceBegin(Trace.TRACE_TAG_INPUT, "Launcher.startActivity");
            if (useLaunchAnimation) {
                ActivityOptions opts = ActivityOptions.makeScaleUpAnimation(v, 0, 0,
                        v.getMeasuredWidth(), v.getMeasuredHeight());
                startActivity(intent, opts.toBundle());
            } else {
                startActivity(intent);
            }
            /// M: add systrace to analyze application launche time.
            Trace.traceEnd(Trace.TRACE_TAG_INPUT);
            return true;
        } catch (SecurityException e) {
            Toast.makeText(this, R.string.activity_not_found, Toast.LENGTH_SHORT).show();
            Log.e(TAG, "Launcher does not have the permission to launch " + intent +
                    ". Make sure to create a MAIN intent-filter for the corresponding activity " +
                    "or use the exported attribute for this activity. "
                    + "tag=" + tag + " intent=" + intent, e);
        }
        return false;
    }
