饺子播放器导入问题Compilation failed to complete，Invoke-customs are only supported starting with Android O (-

具体是错误，开始导入饺子播放器时，在我的项目build.gradle文件中直接 implementation 'cn.jzvd:jiaozivideoplayer:6.4.1'，然后sync now，一次性通过，心喜如狂。没想到饺子这么好用，一次导入通过了。

接着悲剧来了，开始run项目，竟然报错了，如下

com.android.builder.dexing.DexArchiveBuilderException: com.android.builder.dexing.DexArchiveBuilderException: Failed to process C:\Users\Administrator\.gradle\caches\transforms-1\files-1.1\jiaozivideoplayer-6.4.1.aar\b3cc5c726cd66a1c08214d9b00bd0eaf\jars\classes.jar具体是

关键来了，百度，google半天无解，认真读了一遍bug日志，英语限制我的理解能力，。。。。终于发现日志中有一句，好像是提醒我

The dependency contains Java 8 bytecode. Please enable desugaring by adding the following to build.gradle
android {
    compileOptions {
        sourceCompatibility 1.8
        targetCompatibility 1.8
    }
}
See https://developer.android.com/studio/write/java8-support.html for details. Alternatively, increase the minSdkVersion to 26 or above.

试着在build.gradle中添加

compileOptions {sourceCompatibility JavaVersion.VERSION_1_8targetCompatibility JavaVersion.VERSION_1_8}

如图

然后 sync now，然后run，通过了，啦啦啦啦
