Unable To Access Views In Android

I am using metaio sdk. I am trying to simply toggle the visibility of two imageviews when pressing a button but it is not working. My layout: Copy

Solution 2:

I guess the error is at 'R', All you need to do is import your package.R

Example

...    
import com.yourpackage.yourappname.R; //Import this@OverridepublicvoidonCreate(Bundle savedInstanceState) {
    MetaioCloudPlugin.startJunaio(null, getApplicationContext());
    super.onCreate(savedInstanceState);
    setContentView(R.layout.mainactivity);
...

Then it should work fine :D

Solution 3:

I encountered the same issue before. I managed to solve it by clearing the cache, data and uninstall the app from the device. It is working after I re-publish the app to the testing device. Maybe you could try it.
