Manifest merger failed : uses-sdk:minSdkVersion 1 cannot be smaller than version 7

移植到Android studio，报错：

Error:(5, 5) uses-sdk:minSdkVersion 1 cannot be smaller than version 4

Error:(5, 5) Execution failed for task ':library:processDebugAndroidTestManifest'.
> : Manifest merger failed : uses-sdk:minSdkVersion 1 cannot be smaller than version 4 declared in library /user/library/build/intermediates/exploded-aar//support-v4/22.1.0/
  Suggestion: use tools:overrideLibrary=".v4" to force usage

解决方法：修改文件

<?xml version="1.0" encoding="utf-8"?>

<manifest
   xmlns:android="/apk/res/android"
   package=""
   android:versionCode="60"
   android:versionName="2.4.0">
   
    <uses-sdk android:minSdkVersion="1" />

</manifest>

为

<?xml version="1.0" encoding="utf-8"?>

<manifest
   xmlns:android="/apk/res/android"
   package=""
   android:versionCode="60"
   android:versionName="2.4.0">
   
    <uses-sdk android:minSdkVersion="7" />

</manifest>
