[Android]：java.lang.NoSuchFieldError：

Question

尝试在 UI 上显示错误消息时出现以下错误TextInputLayout：E/AndroidRuntime: FATAL EXCEPTION: main    Process: com.blablabla.appname, PID: 23691    java.lang.NoSuchFieldError: No field error_color_material of type I in class Landroid/support/v7/appcompat/R$color; or its superclasses (declaration of 'android.support.v7.appcompat.R$color' appears in /data/app/com.blablabla.appname-2/split_lib_slice_6_apk.apk)        at android.support.design.widget.TextInputLayout.setErrorEnabled(TextInputLayout.java:654)        at android.support.design.widget.TextInputLayout.setError(TextInputLayout.java:721)        at android.support.design.widget.TextInputLayout.setError(TextInputLayout.java:708)        at com.blablabla.appname.activity.SetupProfileActivity.validateUsername(SetupProfileActivity.java:465)SetupProfileActivity.java:465:private boolean validateUsername() {    final String username = inputUsername.getText().toString().trim();    if (inputUsername.getText().toString().trim().isEmpty()) {        inputLayoutUsername.setError(getText(R.string.username_warning)); // Line 465        requestFocus(inputUsername);        return false;    } else {        inputLayoutFullName.setErrorEnabled(false);    }    return true;}有什么问题？我尝试查找，但找不到与该No field error_color_material消息相关的任何内容。
