我一直在尝试如何为我的应用程序发出通知，打开另一个应用程序，例如收件箱。我只看到了如何打开特定活动，并且不知道是否可以打开整个应用程序。

是。有可能的。您只需要正确配置您的意图。
注意
最终用户可能没有安装你想要的应用程序。所以，你必须实现控制它的方法......
但无论如何，可以从您自己的通知中打开另一个应用
示例
我为whatsapp创建了以下示例。我使用this question作为参考。
Notification.Builder notiBuilder = new Notification.Builder(this);
Intent intent = null;
/*
START
Configure your intent here.
Example below opens the whatspp.. I got this example from https://stackoverflow.com/questions/15462874/sending-message-through-whatsapp/15931345#15931345
You must update it to open the app that you want.
If the app is not found, intent is null and then, click in notification won't do anything
*/
PackageManager pm=getPackageManager();
try {
PackageInfo info = pm.getPackageInfo("com.whatsapp", PackageManager.GET_META_DATA);
intent = new Intent(Intent.ACTION_SEND);
intent.setPackage("com.whatsapp");
intent.setType("text/plain");
} catch (PackageManager.NameNotFoundException e) {
// Package not found
intent = null;
e.printStackTrace();
}
/* END */
if(intent != null) {
PendingIntent clickPendingIntent = PendingIntent.getActivity(
this,
0,
intent,
PendingIntent.FLAG_UPDATE_CURRENT);
notiBuilder.setContentTitle("Title")
.setSmallIcon(R.drawable.common_google_signin_btn_icon_light)
.setContentText("Message")
.setContentIntent(clickPendingIntent)
.setLights(Color.BLUE, 3000, 3000);
} else {
notiBuilder.setContentTitle("Title")
.setSmallIcon(R.drawable.common_google_signin_btn_icon_light)
.setContentText("Message")
.setLights(Color.BLUE, 3000, 3000);
}
Notification mNotificationBar = notiBuilder.build();
mNotificationBar.flags |= Notification.DEFAULT_SOUND;
mNotificationBar.flags |= Notification.FLAG_SHOW_LIGHTS;
mNotificationBar.flags |= Notification.FLAG_AUTO_CANCEL;
NotificationManager mNotificationManager = (NotificationManager) this.getSystemService(Service.NOTIFICATION_SERVICE);
mNotificationManager.notify(0, mNotificationBar);
打开拨号器
只需配置如下的意图：
intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:0123456789"));
