在集成极光推送 SDK 的时候，如果把极光推送集成到一个独立的 AAR 包中，在编译的时候会发生如下报错：

如果是构建单一 APK 的情况下，可以直接在 AAR 项目里面通过 manifestPlaceholders 直接配置这些参数。
但是如果是多渠道打包的情况下，我们会在统一的地方根据不同的渠道进行配置。
这个时候直接在 AAR 项目里面配置就不合适了，此时我们观察报错信息，会发现其实真正报错的地方是执行单元测试的时候报错（processDebugAndroidTestManifest）。
其实也容易理解，执行 AndroidTest 的时候，需要生成单独测的测试 APK，这一步就必须补充完整全部的 meta-data 信息，否则无法顺利生成 APK。
通过上述的分析，解决这个问题就比较简单了，我们只需要在测试用例的时候补充这些 meta-data 信息即可。
那接下来就是怎么生成 AndroidTest 的时候的配置信息，网上搜索很久，才在 Possibility to define manifestPlaceholders or BuildConfig variables just for tests 找到相关的解决方案。
参考解决方法如下：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
apply plugin: 'com.android.library' android { compileSdkVersion 21 buildToolsVersion "21.1.0" defaultConfig { minSdkVersion 15 targetSdkVersion 21 versionCode 1 versionName "1.0" } } android.testVariants.all { it.mergedFlavor.manifestPlaceholders = [ localApplicationId:"com.example.manifest_merger_example.flavor"] } |
