Android Studio常见问题 -- uses-sdk:minSdkVersion 8 cannot be smaller than version 9 declared in library

问题描述

 

* What went wrong:
Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed : uses-sdk:minSdkVersion 8 cannot be smaller than version 9 declared in library D:\AndroidStudioProjects\StudioDemo\app\build\intermediates\exploded-aar\com.umeng\fb\5.1.0\AndroidManifest.xml
Suggestion: use tools:overrideLibrary="com.umeng.fb" to force usage

 

解决方法

在app的AndroidManifest.xml中做如下修改:

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

<manifest xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools"

    package="com.studio.demo">



    <uses-sdk

        android:minSdkVersion="8"

        android:targetSdkVersion="22" tools:overrideLibrary="com.umeng.fb" />



    <application

        android:allowBackup="true"

        android:icon="@mipmap/ic_launcher"

        android:label="@string/app_name"

        android:theme="@style/AppTheme"

        >

        <activity

            android:name=".MainActivity"

            android:label="@string/app_name" >

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />



                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

        </activity>

    </application>



</manifest>

 

 

注意两个地方：

1. 在manifest节点加上：xmlns:tools="http://schemas.android.com/tools"

2. 在uses-sdk节点加上：tools:overrideLibrary="com.umeng.fb"
