标签： android

在尝试运行我的应用程序时，它说我丢失或不支持该应用程序，但是当我添加该类时，它突然不再运行了。我很确定我丢失了一些东西，但是我试图在数小时内找到它我尝试删除它并再次执行该类，但是尝试弄乱build.gradle并更改其版本并还原它并没有起作用

答案 0 :(得分：1)

您可以从string.xml中删除<color name="Black">#000000</color>并尝试构建该应用程序吗？ 更新 ::

<String name="balance">Balance</String>

做到

<string name="balance">Balance</string>

答案 1 :(得分：0)

更改此：

<String name="balance">Balance</String>

小写string 

<string name="balance">Balance</string>

答案 2 :(得分：0)

您的资源声明XML标记应始终小写。

所以您的

<String>

实际上应该是

<string>
