Question

我的应用无法启动，因为错误使类ImageButton膨胀，因此电话显示“应用已停止”等。我正在使用Firebase测试实验室来调试问题

这些错误发生在三星设备上，特别是A20，s7 Edge和s7（经过Firebase相同问题的测试）

我是android的新手，并且尝试了Google的许多解决方案，因此没有一个解决方案

这是关于Firebase的错误报告

Answer 1

这意味着在drawble文件夹中找不到upload_files_upload，这可能是一种情况，您的文件可能出现在drawable-24中，但没有出现在drawble文件夹中，在这种情况下，此问题仍然出现。关键是您的文件必须位于所有drawble文件夹中。

Answer 2

出现错误的原因是upload_files_upload不在您的drawable文件夹中：

<ImageButton
            android:id="@+id/UploadButton"
            android:layout_width="300dp"
            android:layout_height="209dp"
            android:background="@android:color/transparent"
            app:layout_constraintTop_toBottomOf="@+id/flexboxLayout" 
            app:srcCompat="@drawable/upload_files_upload"// this line
            android:contentDescription="@string/todo" />

Answer 3

我已经解决了我将app：srcCompat =“ @ drawable / upload_files_upload” //更改为android：src =“ @ drawable / upload_files_upload”的问题因此问题出在app：srcCompat，我将其更改为Android：src，现在可以正常使用了
