去除重复依赖库优化

关于依赖关系树的结构图如下所示,此处省略很多代码| | | | | | —
android.arch.core:common:1.1.1 (*) | | | | \--- com.android.support:support-annotations:26.1.0 -> 28.0.0 | +--- com.journeyapps:zxing-android-embedded:3.6.0 | | +--- com.google.zxing:core:3.3.2 | | \--- com.android.support:support-v4:25.3.1 | | +--- com.android.support:support-compat:25.3.1 -> 28.0.0 (*) | | +--- com.android.support:support-media-compat:25.3.1 | | | +--- com.android.support:support-annotations:25.3.1 -> 28.0.0 | | | \--- com.android.support:support-compat:25.3.1 -> 28.0.0 (*) | | +--- com.android.support:support-core-utils:25.3.1 -> 28.0.0 (*) | | +--- com.android.support:support-core-ui:25.3.1 -> 28.0.0 (*) | | \--- com.android.support:support-fragment:25.3.1 -> 28.0.0 (*) \--- com.android.support:multidex:1.0.2 -> 1.0.3
