java - "Unable to start activity ComponentInfo"错误

Question

大家好，我遇到了标题错误的问题。我不知道发生了什么，一切正常之前几秒钟...崩溃之前我做的唯一一件事就是在 ACTIVITY MAIN.xml 中更改“项目”的维度从准确的一到“匹配约束”但是当我看到应用程序崩溃，我撤消了所有修改，至少我相信是这样......有人可以帮助我吗？抱歉，如果我不太准确，如果您想了解更多信息，请告诉我!感谢大家!!!

请注意错误是“找不到资源”。

08-27 01:31:22.657 25670-25670/com.example.principale.gapgo E/AndroidRuntime: FATAL EXCEPTION: main Process: com.example.principale.gapgo, PID: 25670 java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.principale.gapgo/com.example.principale.gapgo.MainActivity}: android.content.res.Resources$NotFoundException: Resource ID #0x7f09001b

下面的行看起来有一些问题，因为资源 ID 看起来不是 ASCII 字符串。

Button disponibilita = (Button) findViewById(R.id.buttonDisponibilità);

另请检查引用不存在的资源 ID 的行。

其他相关信息是通过在 gradle.properties 内添加以下行来禁用 android.enableAapt2，如此处所述 https://stackoverflow.com/a/45965816/8034839

android.enableAapt2=false
