Hi i am trying to build my project but i am getting the folowing error

ActivityManager: java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10000000 cmp=com.my_app.app/.choose_language } from null (pid=-1, uid=-1) requires null

            android:theme="@android:style/Theme.NoTitleBar" >

        </activity>
    </application>

</manifest>

if i remove the intent-filter part and add this to my splash screen activity my app starts fine but having this start up code on any other activity throws the above error. Does anyne know why this is?

回答1:

Frequently, requires null in a SecurityException means that the component is not exported. That should not be a problem in your case -- an activity is automatically exported when it has an <intent-filter>. I would settle on which activity in your app will have the <intent-filter>, and do a full uninstall of the app from your device/emulator and then reinstall to see if this helps.

BTW, ordinary SDK applications cannot hold ACCESS_CHECKIN_PROPERTIES.
