1.manifest中注册

在Activity中注册，如下：
注：此为必须存在的

      <intent-filter>
        <action android:name="action.action.action1"/>
        <action android:name="action.action.action2"/>
        <action android:name="action.action.action3"/>
        <action android:name="action.action.action4"/>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.DEFAULT"/>
        <category android:name="android.intent.category.LAUNCHER" />
      </intent-filter>

2.调用

            Intent intent = new Intent(action);
            context.startActivity(intent);

也可以使用命令adb shell am start -a action.action.action1测试

3.接收

3.1 Android获取action

            Intent receiverIntent = getIntent();
            String action =receiverIntent.getAction();

或者

    @Override
    protected void onNewIntent(Intent intent) {
        super.onNewIntent(intent);

        intentResult=intent.getStringExtra(ReceiverTag);

        if(intentResult==null || intentResult == "")
        {
            intentResult=defaultIntentResult;
        }
        Log.d(Tag,"Intent result:"+intentResult);
    }

        {
            Debug.LogErrorFormat("Failed to get Unity Player class, {0}", unityPlayerClass);
            return null;
        }
        AndroidJavaObject activity = jc.GetStatic<AndroidJavaObject>("currentActivity");
        if (activity == null)
        {
            Debug.LogError("Failed to obtain Android Activity from Unity Player class.");

            Debug.Log("Get action result:" + result);
        }
