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>

So after searching on internet over an hour, i have check from project structure that i have not set the default config settings. To resolve this issue you have to open project structure and then add default config and then synced with gradle will solve this issue.

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.
