Android 安装软件后执行“OPEN”引起的Intent血案（系统BUG）

打开程序的入口有很多个：

shell 命令行运行；

Launcher待机界面执行；

状态通知栏运行；

桌面快捷方式运行；

软件中调用运行；

安装软件后执行“OPEN”运行！

前面几项，调用程序的代码如下（参考：com.android.Launcher/.Launcher.java）：

Intent intent = new Intent(this, TestActivity.class);
intent.setAction(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
this.startActivity(intent);

而安装软件后，点击“Open”调用的代码如下（参考：com.android.packageinstaller/.InstallAppDone.java）：

Intent intent = new Intent(this, TestActivity.class);
this.startActivity(intent);

如果用户安装软件后立刻执行“Open”，运行程序后，按HOME键返回到后台，然后再通过别的几种方法运行程序，则会再起一个MAIN程序。这是因为Intent的处理机制是，先比较Activity，再比较Action、Flag、bnds。。。，前后两张方式的Action不一样，一个有LAUNCHER ACTION，一个没有，所以会认为是启动两个不同的INTENT。

目前只想到一个简单的处理方式：

程序入口MAIN程序：SplashActivity.java

程序原入口程序：LoginActivity.java

启动程序后，在状态通知栏上添加快捷通知，代码如下：

package org.anymobile.test;
import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
public class SplashActivity extends Activity
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);

this.showNotification(this.getBaseContext(), -1, "Test is Running!", "Test Start Up!");

Intent intent = this.getIntent();
if (intent.hasCategory(Intent.CATEGORY_LAUNCHER))
{
intent = new Intent(this, TestActivity.class);
this.startActivity(intent);
}
else
{
intent = new Intent();
ComponentName componentName = new ComponentName(this, SplashActivity.class);
intent.setComponent(componentName);
//			intent = new Intent(this, SplashActivity.class);

intent.setAction(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);

this.startActivity(intent);
}

this.finish();
}
public void showNotification(Context context,int iResIcon,String sNotifybar,String sNofitymsg)
{
// look up the notification manager service
NotificationManager nm = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
// The details of our fake message
CharSequence from = "Test";
CharSequence message = sNofitymsg;

Intent intent = new Intent();
ComponentName componentName = new ComponentName(context, TestActivity.class);
intent.setComponent(componentName);

intent.setAction(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);

PendingIntent contentIntent = PendingIntent.getActivity(context, 0, intent, 0);
Notification notification =
new Notification(iResIcon,sNotifybar, System.currentTimeMillis());
notification.flags = notification.flags | Notification.FLAG_ONGOING_EVENT;
notification.defaults =
/*Notification.DEFAULT_SOUND|*/Notification.DEFAULT_LIGHTS;
notification.setLatestEventInfo(context, from, message, contentIntent);
nm.notify(R.string.app_name, notification);
}

}

}

测试流程：

a、软件本地安装；

b、安装后执行“Open”；

c、运行软件会从SplashActivity添加NOTICIFICATION TestActivity；

d、跳转至SplashActivity（附带LAUNCHER ACTION）；

e、再跳转至TestActivity；

f、点击BUTTON，跳转至Test2Activity；

g、下拉状态通知栏，点击程序通知，可以正常运行程序。

TODO: 安装软件后执行OPEN后，从待机界面运行程序，还是会启动两个一样的ACTIVITY，这个问题没有解决！：（
