Answer 1

请修改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 pts = 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; }
