org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:processDebugManifest'.
at org.gradle.api.internal.tasks.execution.ExecuteActionsTaskExecuter.executeActions(ExecuteActionsTaskExecuter.java:103)由报错信息可知，是导入的module的AndroidManifest.xml文件，与原有的该文件中的字段冲突导致的。
执行gradle查看具体信息，gradle的配置详见该文章；
配置gradlew命令行，根据上面的报错信息配置指令：
./gradlew processDebugManifest --stacktrace
获取到具体的错误内容：
/Users/.../app/src/main/AndroidManifest.xml:81:9-36 Error:
Attribute application@allowBackup value=(false) from AndroidManifest.xml:81:9-36
is also present at [:LiteAVSDK_Professional:] AndroidManifest.xml:20:9-35 value=(true).
Suggestion: add 'tools:replace="android:allowBackup"' to <application> element at AndroidManifest.xml:79:5-2242:19 to override.
