Answer 1

you have to define your launcher activity in manifest.

  <activity
    android:name=".MainActivity" //Whatever Activity you want to launch first>
      <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

I had this same problem and solved it by manually setting the launch activity. From the menu select "Run -> Edit Configurations...", and then under "Launch Options" select "Launch: Specified Activity" and "Activity: your.launch.activity" where "your.launch.activity" is the activity you want to launch.
