Android Manifest冲突导致sms权限无效

Question

我遇到这个问题，当在android清单中包含以下代码时发送短信时，短信权限不起作用。

   <activity android:name=".engine.MainActivity" android:label="@string/app_name" android:theme="@style/AppTheme.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

如果我用这个替换这个代码：

 <activity
                android:name=".SendSmsActivity"
                android:label="@string/app_name">
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />
                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
            </activity>

短信开始工作。我也尝试在冲突的代码下添加第二个代码：

 <activity android:name=".ui.SendSmsActivity">

        </activity>

但这也不起作用。任何帮助将不胜感激。我已经被困在这几天了。
