You must change your manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="bizsalt.drawer2">
<application
android:allowBackup="true"
android:icon="@mipmap/gargi_blue"
android:label="@string/app_name"
android:theme="@style/AppTheme">
<activity
android:name=".SplashScreenActivity"
android:label="XYZ"
android:theme="@style/AppTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".LoginActivity"
android:label="XYZ"
android:theme="@style/AppTheme"
/>
<activity
android:name=".RegisterActivity"
android:label="XYZ"
android:theme="@style/AppTheme"
/>
<activity
android:name=".MainActivity"
android:label="XYZ"
android:theme="@style/AppTheme"
/>
</application>
</manifest>
And in your SplashScreenActivity. Put code to transit to LoginActivity:
Intent mIntent = new Intent(SplashScreenActivity.this,LoginActivity.class);
startActivity(mIntent);
Do same with other Activity
