答案 0 :(得分：0)

minSdkVersion是控制此处旧版本的工具。

更改

minSdkVersion 23

如果您希望您的应用程序支持最高棒棒糖版本的设备，则为21。通常，这些天开发人员正在使用minSdkVersion21。如果遇到任何错误，可以轻松修复。

希望这会为您提供适当的指导。

Activity.LoginActivity}：android.view.InflateException：二进制XML   文件行＃57：二进制XML文件行＃57：膨胀类Button时出错

     

原因：android.content.res.Resources $ NotFoundException：资源   “ com.example.ananduamenon.a2z_final：drawable / button_background”   （7f07005e）不是Drawable

我认为您需要更仔细地阅读错误堆栈跟踪。如我所见，您使用了一些 button_background ，这些属性不能令人满意的膨胀属性（可绘制/彩色）。我建议您检查您的 button_background.xml 文件并弄清楚您写错了什么。

答案 2 :(得分：0)

您是否有为旧版Android定义了单独的资源（可绘制，布局）文件的信息？ 您的堆栈跟踪表明，由于缺少可绘制对象，它无法使按钮膨胀。

答案 3 :(得分：0)

minSdkVersion 23

将其设置为较低的版本，例如minSdkVersion 19

，并在您的代码中检查版本低于23的版本是否实现了其他情况或禁用了诸如以下功能：

if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
           // implement your logic here
        } else {
            // implement another scenario or disable this feature 
        }
