    **Check your manifest.. you are probabaly missing the intent filter that I have shown in snippet.**

 <activity
            android:label="main"
            android:name=".mainActivity" >
             <intent-filter >
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

    You need to declare you activity in your manifest file.

    <application
        android:allowBackup="false"
        android:icon="@drawable/logo"
        android:label="App Name"
        android:roundIcon="@drawable/logo"
        android:supportsRtl="true"
        android:theme="@style/AppTheme"
        android:usesCleartextTraffic="true"
        tools:replace="android:theme,android:allowBackup,android:label"
        tools:targetApi="m">

        <activity android:name="com.app.ui.YourActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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