Hi,
I created an Android application that has to run on a fully managed device.
I have to make it the only application installed on a device and running on a Kiosk Mode.
I tried provisioning the device using QR Code, to do it I do the following:
Created an activity extending DeviceAdminReceiver.
import android.app.admin.DeviceAdminReceiver
class AdminReceiver : DeviceAdminReceiver()
Added it into the manifest:
<receiver
android:name=".kioskmode.AdminReceiver"
android:exported="true"
android:label="@string/app_name"
android:permission="android.permission.BIND_DEVICE_ADMIN">
<meta-data
android:name="android.app.device_admin"
android:resource="@xml/device_admin" />
<intent-filter>
<action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
</intent-filter>
</receiver>
Created activity to handle ADMIN_POLICY_COMPLIANCE and GET_PROVISIONING_MODE:
<activity
android:exported="true"
android:name=".dpc.AdminPolicyComplianceActivity"
android:permission="android.permission.BIND_DEVICE_ADMIN">
<intent-filter>
<action android:name="android.app.action.ADMIN_POLICY_COMPLIANCE"/>
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity
android:exported="true"
android:name=".dpc.ProvisioningModeActivity"
android:permission="android.permission.BIND_DEVICE_ADMIN">
<intent-filter>
<action android:name="android.app.action.GET_PROVISIONING_MODE" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
class AdminPolicyComplianceActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setResult(RESULT_OK, resultIntent)
finish()
}
}
class ProvisioningModeActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
val resultIntent = Intent()
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
resultIntent.putExtra(DevicePolicyManager.EXTRA_PROVISIONING_MODE,
DevicePolicyManager.PROVISIONING_MODE_FULLY_MANAGED_DEVICE)
}
setResult(RESULT_OK)
finish()
}
}
I created the QR code using the codelab and edited the code to the following:
{
"android.app.extra.PROVISIONING_DEVICE_ADMIN_COMPONENT_NAME": "com.myapp/com.myapp.kioskmode.AdminReceiver",
"android.app.extra.PROVISIONING_DEVICE_ADMIN_PACKAGE_DOWNLOAD_LOCATION": "https://www.dropbox.com/scl/xxxxx",
"android.app.extra.PROVISIONING_DEVICE_ADMIN_SIGNATURE_CHECKSUM": "xxxxxxx",
"android.app.extra.PROVISIONING_LEAVE_ALL_SYSTEM_APPS_ENABLED": true,
"android.app.extra.PROVISIONING_WIFI_SSID": "xxxxx",
"android.app.extra.PROVISIONING_WIFI_HIDDEN": false,
"android.app.extra.PROVISIONING_WIFI_SECURITY_TYPE": "WPA",
"android.app.extra.PROVISIONING_WIFI_PASSWORD": "xxxxxxx",
"android.app.extra.PROVISIONING_SKIP_ENCRYPTION": false,
"android.app.extra.PROVISIONING_ADMIN_EXTRAS_BUNDLE":
{
"com.google.android.apps.work.clouddpc.EXTRA_ENROLLMENT_TOKEN": "xxxxxx"
}
}
but I always get the error "Can't set up device. Contact your IT admin for help"
If I try to provision the app using this qr code https://github.com/googlesamples/android-testdpc/tree/master
it works well on the same device.
Is there anything that I am missing?
Regards.

Sorry I noticed there was an error here:
class ProvisioningModeActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
val resultIntent = Intent()
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
resultIntent.putExtra(DevicePolicyManager.EXTRA_PROVISIONING_MODE,
DevicePolicyManager.PROVISIONING_MODE_FULLY_MANAGED_DEVICE)
}
setResult(RESULT_OK, resultIntent) // I wasn't returning the result intent.
finish()
}
}
