Activity 的 OnCreate 中的 getIntent() 是否可以从 AlarmManager 获取 PendingIntent 传递的额外数据以用于自身 Activity 重启？

Question

10 秒后启动 alarmManager 的代码

Intent intent=new Intent(SelfUpdateByScanQrCodeEventActivity.getContext(), MainActivity.class);
            intent.putExtra("startInstallUpdateApk",true);
            PendingIntent pendingIntent = PendingIntent.getBroadcast(
                    SelfUpdateByScanQrCodeEventActivity.getContext().getApplicationContext(), createRestartAgentAlarmManagerRequestCode, intent, PendingIntent.FLAG_UPDATE_CURRENT);
            AlarmManager alarmManager = (AlarmManager) SelfUpdateByScanQrCodeEventActivity.getContext().getSystemService(ALARM_SERVICE);
            Calendar cal = Calendar.getInstance();
            cal.add(Calendar.SECOND,delaySecTimeToRestartAgent);
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                alarmManager.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP,cal.getTimeInMillis(),pendingIntent);
                
            }else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
                alarmManager.setExact(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);
               
            } else {
                alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);
                
            }

MainActivity的cod

public class MainActivity extends Activity {
@Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_preparation);
        Bundle extras = this.getIntent().getExtras();
        boolean startInstallUpdateApk = extras.getBoolean("startInstallUpdateApk");
}
}

MainActivity 调用后的onCreate startInstallUpdateApk 能拿到key吗？

简单回答你的问题

Can I get the key,"startInstallUpdateApk" , onCreate after MainActivity called?

是“是”。然而...

您的代码在应调用 PendingIntent.getActivity() 时却调用了 PendingIntent.getBroadcast()。当警报触发时，现在什么也不会发生，因为 Activity Intent 和广播 Intent 是两个完全不同的东西。
