My Android app is not displaying the application name "app_name",I have multiple activities but when I restart the app, the first page of the app doesn't show the app name but in other activities it shows the app name. i don't know what is wrong anyone can help me.

Strange behaviour of an alphaApk's shortcut

I have noticed that my application that is published to an Alpha test has a strange behaviour... The shortcut is launching the MainActivity again. Everything is working fine when it's installed via generated .apk
My Android-Manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.YYY.XXX">
<application
android:name=".Infrastructure.XXXApplication"
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme">
<activity
android:name=".activities.MainActivity"
android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".activities.BaseActivity" />
<activity
android:name=".activities.SettingsActivity"
android:screenOrientation="portrait"/>
<activity
android:name=".activities.SavedResultsActivity"
android:screenOrientation="portrait"/>
</application>
</manifest>

Default Activity not found Waiting for process

When I am trying to debug-run my application I am getting this error in console:
Default Activity not foundWaiting for process: com.myapp.myapp
My AndroidManifest look like this:
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme">
<activity
android:name="com.myapp.myapp.Splash"
android:label="#string/app_name"
android:noHistory="true">
<intent-filter>
<action android:name="android.intent.action.Main" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.myapp.myapp.Main"
android:label="#string/app_name"
android:launchMode="singleInstance"
android:windowSoftInputMode="adjustPan">
<intent-filter>
<action android:name="android.intent.action.Main" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
This doesn't work for me because I can't find any sources tab as mentioned there.

For the second activity, in intent filter, change android:name to com.myapp.myapp.Main .
