我的应用在启动时崩溃！请帮忙！

这是我的代码

    String manufacturer = Build.MANUFACTURER;
    String model = Build.MODEL;
    if (model.startsWith(manufacturer)) {
        return capitalize(model);
    }
    return capitalize(manufacturer) + " " + model;
}

private static String capitalize(String str) {
    if (TextUtils.isEmpty(str)) {
        return str;
    }
    char[] arr = str.toCharArray();
    boolean capitalizeNext = true;
    String phrase = "";
    for (char c : arr) {
        if (capitalizeNext && Character.isLetter(c)) {
            phrase += Character.toUpperCase(c);
            capitalizeNext = false;
            continue;
        } else if (Character.isWhitespace(c)) {
            capitalizeNext = true;

检查您的依赖项并添加（如果您还没有的话）：

implementation 'com.google.firebase:firebase-auth:16.0.3'
implementation 'com.crashlytics.sdk.android:crashlytics:2.9.5'

阅读：https://firebase.google.com/docs/android/setup

Android Studio已经具有 Connect to Firebase 选项，这对添加Firebase及其依赖项有很大帮助：https://developer.android.com/studio/write/firebase
