Error:(72) unknown element <receiver> found

问题

I am using Dji-SDK. Recently i migrated the SDK from version 4.2 to 4.3.2. After changing the dji-sdk.aar in the libs folder i am not able to build because of the merge issues in the manifest. The merged manifest in build is getting created as follows.

...
<uses-permission android:name="android.permission.USE_CREDENTIALS" />

    <receiver
        android:name="dji.logic.receiver.DJIPilotStartupReceiver"
        android:exported="true"
        android:permission="dji.permission.sdk.wifi" >
        <intent-filter>
            <action android:name="dji.pilot.STARTUP" />
            <action android:name="dji.go3.STARTUP" />
            <action android:name="dji.go4.STARTUP" />
        </intent-filter>
    </receiver>

    <application
        android:name="com.sample.app.LinkApplication"
...

I know that the receiver tag should come under application tag. But in the merged manifest the tag is under the uses-permission tag and showing an error. Is it an Sdk error or is it wrong on my side ? Error is

Error:(71) unknown element <receiver> found

回答1:

Try disabling the AAPT2 by adding android.enableAapt2=false to your gradle.properties file.

Builds may fail while AAPT2 is enabled. Additionally, AAPT2 is currently not compatible with Robelectric. If your build fails due to an AAPT2 resource processing issue or you want to use Roboelectric, you can disable AAPT2 by setting android.enableAapt2=false in your gradle.properties file and restarting the Gradle daemon by running ./gradlew --stop from the command line.

Reference : here

I was using Android studio 3.0 beta 5 In which I disabled the AAPT2 and it resolved my error.

UPDATE :

As Jay has mentioned another solution could be update Android Studio to 3.1.1. Since updating has solved issue for him. I haven't cross checked though.
