【问题描述】:
当我尝试构建我的项目时。我得到了这个错误
程序类型已存在:android.support.v4.accessibilityservice.AccessibilityServiceInfoCompat Message{kind=ERROR, text=Program type already present: android.support.v4.accessibilityservice.AccessibilityServiceInfoCompat, sources=[Unknown source file], tool name=Optional.of(D8)}
我也在堆栈溢出中找到解决方案,但没有帮助。这是我的 build.gradle 文件
apply plugin: 'com.android.application'android {
compileSdkVersion 28
defaultConfig {
applicationId "com.example.hassan.qrscan"
minSdkVersion 18
targetSdkVersion 28
