“java.lang.SecurityException：尝试删除非测试管理员”，同时尝试删除设备管理员

Question

我无法从我的 Android 12.1 设备中删除设备所有者。

当我在 adb shell 中使用

dpm list-owners

时，我得到以下输出：

1 owner:\n User  0: admin=package.name/app.receivers.DeviceAdminReceiver,DeviceOwner,Affiliated

当我在 adb shell 中使用

dpm remove-active-admin package.name/app.receivers.DeviceAdminReceiver

时，我得到以下输出：

Exception occurred while executing 'remove-active-admin':
java.lang.SecurityException: Attempt to remove non-test admin ComponentInfo{package.name/app.receivers.DeviceAdminReceiver} 0

        at android.os.Binder.execTransact(Binder.java:1143)

我还尝试从设置中的安全性禁用设备管理应用程序，但禁用文本也显示为灰色。 我该怎么办？

将此行添加到 Android 清单应用程序标记中：

android：testOnly =“true”

像这样：

 <application
        android:name=".presentation.DpcApplication"
        android:icon="@mipmap/ic_launcher"
        android:testOnly="${testOnly}"/>

在 build.gradle 中：

 buildTypes {
        debug {
            isDebuggable = true
            defaultConfig {
                manifestPlaceholders["testOnly"] = "true"
            }
        }
        release {
            isDebuggable = false
            defaultConfig {
                manifestPlaceholders["testOnly"] = "false"
            }
            isMinifyEnabled = true
            proguardFiles(
                getDefaultProguardFile("proguard-android-optimize.txt"),
                "proguard-rules.pro"
            )
            signingConfig = signingConfigs.getByName("debug")
        }
    }

不要在生产中使用 android:testOnly="true"
