反应原生错误：'权限拒绝：启动意图“

Question

我设法将facebook登录和谷歌登录添加到我的应用程序，但我想我可能做错了什么。在我开始添加登录之前，我之前做了一个用户意图的启动活动，因为我是一个新手，我搞砸了某个地方并且已经挣扎了两天知道。每当我尝试做反应本机run-android时，项目正在构建成功，但模拟器不会自动打开应用程序，因为我得到“开始：

Intent { cmp=com.happyo/.MainActivity }
java.lang.SecurityException: Permission Denial: starting Intent { flg=0x10000000 cmp=com.happyo/.MainActivity } from null (pid=4430, uid=2000) not exported from uid 10085".

请我绝望，我不知道如何解决它，提前谢谢！

这是我的AndroidManifest.xml：

在清单中，只需将<action android:name="android.intent.action.MAIN" />活动标签中的<intent-filter>复制Splash：

<activity
  android:name=".SplashActivity"
  android:label="@string/app_name"
  android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
  android:windowSoftInputMode="adjustResize"
  android:theme="@style/SplashTheme">
  <intent-filter>
    <action android:name="android.intent.action.MAIN" />
     <category android:name="android.intent.category.LAUNCHER" />
  </intent-filter>
</activity>

并像这样粘贴在<activity android:name=".MainActivity" />标记内：

<activity android:name=".MainActivity">
  <intent-filter>
    <action android:name="android.intent.action.MAIN" />
  </intent-filter>
</activity>
