NullPointerException in TextInputLayout on Xiaomi with Android 10

Question

I recently started using TextInputLayout in my android app. After that, strange NullPointerException errors started to appear. These errors only occur on Xiaomi devices with Androind 10 .

Fatal Exception: java.lang.NullPointerException
Attempt to invoke direct method 'void android.widget.Editor$SelectionModifierCursorController.initDrawables()' on a null object reference
android.widget.Editor$SelectionModifierCursorController.access$300

There is no way to reproduce the error (I do not have a Xiaomi device). Searching the Internet realized that this error occurs when trying to enter email in the TextInputLayout field.

There is a solution for React Native on the internet: https://github.com/facebook/react-native/issues/27204

Unfortunately, I have not been able to find a solution for Java.

Answer 1

This is what I did to fix the crash. It will disable the cursor when editing an email address, but it will not crash.

if (android.os.Build.MANUFACTURER.equals("Xiaomi", ignoreCase = true) &&
    android.os.Build.VERSION.SDK_INT == android.os.Build.VERSION_CODES.Q) {
    editText.isCursorVisible = false
}
