intent 常见几种实用
?
Intent应该算是Android中特有的东西。你可以在Intent中指定程序要执行的动作（比如：view,edit,dial），以及程序执行到该动作时所需要的资料。都指定好后，只要调用startActivity()，Android系统会自动寻找最符合你指定要求的应用程序，并执行该程序。
打开其他APK文件的ACTIVITY
Intent mIntent = new Intent();
ComponentName comp = new ComponentName("com.android.a","com.android.a.AbcActivity" );
mIntent.setComponent(comp);
mIntent.setAction("android.intent.action.MAIN");
startActivity(mIntent);
