Android: android.content.res.Resources$NotFoundException: String resource ID #0x5

I get the exception from the title when I run my app. What it does is it has a .txt file with words for a Hangman game and I think the exception is thrown when accessing the file. My file, cuvinte.txt is located into /assets/. Here is my code (i skipped the layout/xml part, which works fine):

public void onCreate() {
    // all the onCreate() stuff, then this:
    try {
        AssetManager am = this.getAssets();
	    InputStream is = am.open("cuvinte.txt");
	    InputStreamReader inputStreamReader = new InputStreamReader(is);
        BufferedReader b = new BufferedReader(inputStreamReader);
	    String rand;
	    while((rand=b.readLine())!=null){
            cuvinte.add(rand);
  	    }
    } catch (IOException e) {
        Toast.makeText(this, "No words file", Toast.LENGTH_LONG).show();
        e.printStackTrace();
    }
      
    newGame(newG);
}
    
public void newGame(View view){
  	Random rand = new Random();
   	String stringCuvant = cuvinte.get(rand.nextInt(cuvinte.size()));
   	cuvant.setText("");
   	System.out.println(stringCuvant);
   	for(int i = 0; i< stringCuvant.length(); i++){
   		cuvant.append("_ ");
   	}
   	incercari.setText(valIncercari);
}

The function newGame() is called both when the new game button is pressed and at the beginning of the activity, in the onCreate() function.

(Just assumption, less info of Exception stacktrace)

I think, this line, incercari.setText(valIncercari); throws Exception because valIncercari is int

So it should be,

incercari.setText(valIncercari+"");

Or

incercari.setText(Integer.toString(valIncercari));

Another scenario that can cause this exception is with DataBinding, that is when you use something like this in your layout

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">

    <data>

        <variable
            name="model"
            type="point.to.your.model"/>
    </data>
    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="@{model.someIntegerVariable}"/>
        
</layout>

Notice that the variable I'm using is an Integer and I'm assigning it to the text field of the TextView. Since the TextView already has a method with signature of setText(int) it will use this method instead of using the setText(String) and cast the value. Thus the TextView thinks of your input number as a resource value which obviously is not valid.

Solution is to cast your int value to string like this

android:text="@{String.valueOf(model.someIntegerVariable)}"

Just wanted to point out another reason this error can be thrown is if you defined a string resource for one translation of your app but did not provide a default string resource.

Example of the Issue:

As you can see below, I had a string resource for a Spanish string "get_started". It can still be referenced in code, but if the phone is not in Spanish it will have no resource to load and crash when calling getString().

values-es/strings.xml

<string name="get_started">SIGUIENTE</string>

Reference to resource

textView.setText(getString(R.string.get_started)

Solution to the Issue##

Preventing this is quite simple, just make sure that you always have a default string resource in values/strings.xml so that if the phone is in another language it will always have a resource to fall back to.

values/strings.xml

<string name="get_started">Get Started</string>

values-en/strings.xml

<string name="get_started">Get Started</string>

values-es/strings.xml

<string name="get_started">Siguiente</string>

values-de/strings.xml

<string name="get_started">Ioslegen</string>

This problem mostly occurs due to the error in setText() method

Solution is simple put your Integer value by converting into string type as

textview.setText(Integer.toString(integer_value));

Sometime this happened due to not fond any source like if i want to set a text into a textview from adapter then i should use

 textView.setText(""+name);

If you write something like

 textView.setText(name);

this will not work and sometime we don't find the resource from the string.xml file then this type of error occur.

Using DataBinding and setting background to the EditText with resources from the drawable folder causes the exception.

<EditText
    android:background="@drawable/rectangle"
    android:imeOptions="flagNoExtractUi"
    android:layout_width="match_parent"
    android:layout_height="45dp"
    android:hint="Enter Your Name"
    android:gravity="center"
    android:textColorHint="@color/hintColor"
    android:singleLine="true"
    android:id="@+id/etName"
    android:inputType="textCapWords"
    android:text="@={viewModel.model.name}"
    android:fontFamily="@font/avenir_roman" />

Solution

I just change the background from android:background="@drawable/rectangle" to android:background="@null"

Clean and Rebuild the Project.

Sometime we add resources in dimen or any other recourse folder, we forget to add dp.

<dimen name="exercise_value">4</dimen>

For example, I was facing this issue because I forgot to add dp in my value.
Then I changed it into

<dimen name="exercise_value">4dp</dimen> <br>

Boom. Error is gone.

In order to solve it I had to replace:

Toast.makeText(this, my_int_var, Toast.LENGTH_SHORT).show();

with this:

Toast.makeText(this, String.valueOf(my_int_var), Toast.LENGTH_SHORT).show();

You are assigning a numeric value to a text field. You have to convert the numeric value to a string with:

String.valueOf(variable)
