我已经通过stackoverflow检查了这个问题并尝试了解决方案，但这里没有运气是我尝试过的参考链接link1link2

Answer 1

检查 android:exported 是否按照here 给出的安全说明设置为 false。如果是，那么您需要将其设置为 true 以使用 USB 调试在您的手机上测试应用程序，如下所示：

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

Answer 2

您将SplashActivity 注册了两次。

<activity android:name="com.srikanth.SplashActivity" >
    </activity>

 <activity
        android:name="com.srikanth.SplashActivity"
        android:label="@string/app_name"
          android:exported="true"
        android:screenOrientation="portrait" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

所以只需要删除其中一个并添加android:exported="true"
