Android 外部啟動activity，自定義action，action常量大全
https://www.cnblogs.com/guop/p/5067342.html
從任意app，啟動另外一個app的activity：
1. Intent i = new Intent();
ComponentName cn = new ComponentName("com.book.android2", "com.book.android2.AndroidSearch");
i.setComponent(cn);
i.setAction("android.intent.action.MAIN");
startActivity(i); //or startActivityForResult(i, RESULT_OK);
我用這種方法時，絕大部分應用可以啟動，但是像RootExplorer卻無法啟動，出現FC對話方塊,因此建議使用下面這種方式：
2. Intent it = new Intent("android.intent.action.MAIN");
it.setClassName("com.speedsoftware.rootexplorer","com.speedsoftware.rootexplorer.RootExplorer");
startActivity(it);
如果你需要啟動一個你自己寫的另一個app的activity，你可以在那個的menifest.xml裡自定義activity的action:
< activity android:name =" .MainActivity " android:label =" @string/app_name " android:theme ="
<intent-filter>
<action android:name=" com.qylk.call.main" /> <!-- 自定義的action-->
<action android:name=" android.intent.action.MAIN" />
<category android:name=" android.intent.category.LAUNCHER" />
<category android:name=" android.intent.category.DEFAULT" /><!--必須加上這個，否則下面無法直接使用自定的action-->
</intent-filter>
</activity>
其他地方啟動它： Intent it = new Intent(" com.qylk.call.main "); startActivity(it);
3.使用adb啟動activity：
啟動RootExolorer：
am start -a android.intent.action.MAIN -n com.speedsoftware.rootexplorer/.RootExplorer
啟動系統設定：
am start -a android.settings.SETTINGS
