Crashing due to “No package identifier when getting value of resource number…” [duplicate]

Answer 1

Android doesn't allow uppercase resource names

Rename

R.id.game_Answer1

to

game_answer_one

etc for the other's you have

Answer 2

It's quite late to answer, though might be useful for those to will find this thread through search.

The setText method requires the identifier as an argument. So, there should be a string in the values/strings.xml with name like "empty_answer", containing the value "-". In other words, the line like: -

Then the setText should be called like: g_answera.setText(R.string.empty_answer);

Possibly, what happens in your case is that the string "-" was somehow turned into resource id 0x0000000d, which of course doesn't exist in your app. Although it's strange that such code was compiled.

One more comment: in Android it IS POSSIBLE to name resources like IDs with Capital characters. What is NOT possible - to have Capital chars in the NAME of resource files.

Answer 3

in your R.java file, does an id for gamelayout exist? This should be located in public static final class layout { } in the R file? Thats the first important step in determining why your application crashes.

Answer 4

Android (unfortunately) doesn't accept resource identifiers with upper-case letters. Also, make sure you are defining your namespace in the root view.

<?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        >
        <TextView 
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content" 
            android:id="@+id/game_answer1" 
            android:text="A" 
            android:paddingLeft="20dp" 
            android:paddingRight="20dp" 
            android:layout_gravity="left" 
            android:clickable="true" 
            android:textSize="100sp" 
            android:layout_alignParentLeft="true" 
            android:textColor="#090999" 
            android:background="#ccccFF"
            />             
    </RelativeLayout>

Answer 5

I ran into this same issue a while ago, I assume that it is fixed but I figured an alternative answer is always welcome :) When using the setText() method you CANNOT send through primitive data types such as int and double, rather convert to string and then send through the string. This fixed my issue when it popped up

Answer 6

there might be others errors in your project because of which your R.java is not created well. hence while executing it is not getting the resource with that id. R.id contains id of all the resources in your projects.
