This is my main activity. I am running Juno on windows 8.1.

I know "R cannot be resolved" has been asked so many times i just cannot find an answer that helps me. i have "R" errors on lines 14,21, and 31.

I also have the Error: No resource found that matches the given name (at 'src' with value '@drawable/Guacamole'). activity_main.xml line 32

I have a project due tomorrow and any help is greatly appreciated, if any has any tips on running Eclispe in 8.1 that would also be appreciated.

I have already tried cleaning my project and these errors are not resolved. — Chandler C, Sep 06 '14 at 21:12
My professor has said to expect complications with windows 8.1, i did not know if this error involved 8.1 or not. sorry. — Chandler C, Sep 06 '14 at 21:20
No worries. To clarify, the windows-8.1 tag is in fact for "the new features and APIs [Windows 8.1 introduces] for developers of Windows Store apps". In short, please don't use it unless you're developing a Windows Store app, which you aren't. — Léo Lam, Sep 06 '14 at 21:22

See you at your code again

<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignRight="@+id/button1"
android:layout_below="@+id/textView1"
android:layout_marginTop="48dp"
android:src="@drawable/Guacamole" />

<ImageView
android:id="@+id/imageView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/textView1"
android:layout_centerHorizontal="true"
android:src="@drawable/guacamole" />

in the second image view the @drawale/guacamoleis in small and in first one is big @drawable/Guacamole thats it.

Thanks for that, and what line should i add the Import R code? – Chandler C Sep 06 '14 at 21:17
well i think the above code should solve your problem but if it doesn't then write the import code at the top below your package name – SyedAliNaqi Sep 06 '14 at 21:19

error become because you use incorrect name for your drawable.
drawable just can use lowwer case leeter (a-z and number,not start with number)

While naming images in res/drawable folder never use capital letters. You can use numbers but don't start the name with a number. In your case you have given Guacamole which has a capital 'G'.Change it so something else and use the same name in your layout as android:src="@drawable/somegoodname"

Also be sure that in your activity, you have not imported R.android., instead of import R.YOUR PACKAGE NAME..

If this doesn't solve your problem please refer r-cannot-be-resolved-android-error to find out various reasons of generating this error.
