解决Android Studio编译时INSTALL_FAILED_MISSING_SHARED_LIBRARY错误，提示 unavailable shared library wearable的问题

1.问题现象

在编译app时安装到虚拟器上时，突然报错：

16:24	Executing tasks: [:app:assembleDebug] in project D:\Android\Projects\AiAgriculture

16:24	Gradle build finished in 7 s 949 ms

16:24	Failed to commit install session 579333955 with command pm install-commit 579333955. Error: INSTALL_FAILED_MISSING_SHARED_LIBRARY: Package couldn't be installed in /data/app/xx.xxx.xxx-1: Package xx.xx.xxx requires unavailable shared library com.google.android.wearable; failing!

16:24	Error
			Installation did not succeed.
			The application could not be installed: INSTALL_FAILED_MISSING_SHARED_LIBRARY
			Retry

16:24	Session 'app': Installation did not succeed.
			The application could not be installed: INSTALL_FAILED_MISSING_SHARED_LIBRARY
			Retry

2.原因分析

在错误提示中，Package xx.xx.xxx requires unavailable shared library com.google.android.wearable; failing!已经对编译失败原因进行了说明，就是在虚拟器上缺少com.google.android.wearable库，导致编译失败。也就是说，app类型搞错了，把用于WATCH上的app编译到了Phone类型的设备上。

3.问题解决

（1）检查AndroidManifests.xml文件中，是否因为use-feature设置成了WATCH，若有，则去掉；

（2）检查Module:xx.app的build.gradle文件，是否有编译限制，若有，则删掉：

 重新编译，问题解决
