【问题描述】:
在我尝试初始化它崩溃的两个引用之后,在我的主 Activity 中,只发现错误 “FirebaseApp 初始化不成功”
private StorageReference mStorageReference;
private DatabaseReference mDatabaseReference;
mStorageReference = FirebaseStorage.getInstance().getReference("uploads");
mDatabaseReference = FirebaseDatabase.getInstance().getReference("uploads");
私有声明和代码本身之间有一些代码,但这与这个问题无关
清单是:

我使用 Tools-Firebase 设置了所有内容,并且我知道代码看起来像是粘在一起的,因为确实如此。我一直在经历线程,只是添加了一些东西,但没有任何效果。如果这很重要,我是在手机上运行应用程序,而不是模拟器。
【问题讨论】:
-
我在您的代码中看不到
firebase-core的实现。你加过implementation 'com.google.firebase:firebase-core:16.0.7'吗? -
添加了firebase-core的实现,仍然崩溃。输出:I/FirebaseInitProvider:FirebaseApp 初始化不成功
-
“它正在崩溃”不是正确的错误描述。
