集成推送和IM 出现的问题

Manifest merger failed : Attribute receiver#cn.jpush.android.service.PushReceiver@exported value=(true) from [cn.jiguang.sdk:jpush:4.3.0] AndroidManifest.xml:123:13-36
is also present at [cn.jiguang.sdk:jmessage:2.9.2] AndroidManifest.xml:48:13-37 value=(false).
Suggestion: add 'tools:replace="android:exported"' to element at AndroidManifest.xml:86:9-103:20 to override.

在Manifest  中的```
    <receiver
        tools:replace="android:exported"
        android:name=".receiver.JgPushReceiver"
        android:enabled="true"
        android:exported="false">
        <intent-filter>
            <action android:name="cn.jpush.android.intent.RECEIVE_MESSAGE" />
            <category android:name="xxx" />
        </intent-filter>
    </receiver>

```
添加 tools:replace="android:exported" 但是没有作用
