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

(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));

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>

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)}"
