i defined launcher activity , package name correct. studio can see activities , when run app choosing activity myself works great, have no ideas can be. hope 1 knows whats wrong.

try this.

<activity android:name=".loginactivity" >     <intent-filter>        <action android:name="android.intent.action.main" />        <category android:name="android.intent.category.launcher" />        </intent-filter>  </activity> 

same goes for

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