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'.
> java.lang.RuntimeException: Manifest merger failed : uses-sdk:minSdkVersion 1 cannot be smaller than version 4 declared in library /user/library/build/intermediates/exploded-aar/com.android.support/support-v4/22.1.0/AndroidManifest.xml
  Suggestion: use tools:overrideLibrary="android.support.v4" to force usage

解决方法：修改文件

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

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

</manifest>
