这是我的 build.gradle 文件

    defaultConfig {

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

【问题讨论】：

你能把异常的整个logcat贴出来吗？它可能包含一些有用的东西，例如Caused by: 部分。
@Vucko 我已经用 logcats 编辑了这个问题。
正如您的 logcat 所说，您的可绘制对象没有被正确引用。检查。另外，清理你的项目。
是的，正是这个 ^ 。像这样检查您正在使用的两个可绘制对象：android:drawableLeft="@drawable/ic_lock_icon_png"。我认为这就是问题所在。评论他们两个，看看错误是否再次发生，如果没有，你至少有一个问题。尤其是我提到的那个我觉得很可疑，因为名字中有_png。
引起：android.content.res.Resources$NotFoundException：资源不是Drawable（颜色或路径）：TypedValue{t=0x1/d=0x7f02005a a=-1 r=0x7f02005a} -这条线清楚地表明其中一个资源不是可绘制的。检查 ic_email 或 ic_lock_icon 是否正确。

【解决方案1】：

问题出在您的android:drawableLeft="@drawable/ic_lock_icon_png" drawable left,right 在旧设备中不起作用，因此请将其删除并检查

如果您想要drawableleft，则将您的矢量资产 "ic_lock_icon_png" 更改为图像资产或 jpeg。（推荐图片资源）。
