but when i open new project I see the app. maybe I changed something into the project.what it can be?
I add some files from android folder

Check this answer here. You need to separate your MainActivity actions into their own <intent-filter> tags like below:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<data android:scheme="glassify" android:host="open" />
<action android:name="android.intent.action.VIEW" />
<!-- <category android:name="android.intent.category.DEFAULT" /> -->
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="#string/fb_login_protocol_scheme" />
</intent-filter>
