//1.添加LaunchActivityItem的回调,后面执行activity生命周期会用到 clientTransaction.addCallback(LaunchActivityItem.obtain(new Intent(r.intent), System.identityHashCode(r), r.info, mergedConfiguration.getGlobalConfiguration(), mergedConfiguration.getOverrideConfiguration(), r.compat, r.launchedFromPackage, t...
6. flags(标记),指示Android如何启动目标Activity,设置方法为调用Intent的setFlags方法。 Android SDK中可以使用的Android原生动作,都是Intent类中的静态字符串常量。在创建隐式的Intent来启动应用程序内的Activity或者子Activity的时候,可以使用这些动作(ActivityIntent)。 ACTION_ALL_APPS:打开一个列出所有已安装应用程序的...
Intent sendIntent = new Intent(); sendIntent.setAction(Intent.ACTION_SEND); sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send."); sendIntent.setType("text/plain"); startActivity(Intent.createChooser(sendIntent, getResources().getText(R.string.send_to)); 1. 2. 3. 4. 5...

Intent.FLAG_ACTIVITY_CLEAR_TOP.jpg 如果同时设置了FLAG_ACTIVITY_SINGLE_TOP,在当前栈已有的情况下就不会重建,而是直接回调B的onNewIntent(),Intent.FLAG_ACTIVITY_CLEAR_TOP|SINGLE_TOP.jpg 官方解释如下:For example, consider a task consisting of the activities: A, B, C, D. If D calls start...
看一下上面的两个关键点1跟2,1是同startActivity的completePauseLocked不同的地方,主动finish的prev.finishing是为true的,因此会执行finishCurrentActivityLocked分支,将当前pause的Activity加到mStoppingActivities队列中去,并且唤醒下一个需要走到到前台的Activity,唤醒后,会继续执行stop:privatefinalActivityRecord...
