【错误记录】Android 应用导入 ijkplayer 报错 ( uses-sdk:minSdkVersion 19 cannot be smaller than version 21 decl )

一、报错信息

---

在 Android 应用中 , 使用 ijkplayer , 如果在 build.gradle 中配置了 abiFilters 如下架构

android {
    
    
    defaultConfig {
    
    
        ndk {
    
    
            abiFilters "armeabi-v7a", "arm64-v8a" 
        }
	}
}

打包 so 动态库时 , 就会打包 “armeabi-v7a”, “arm64-v8a” 这两个架构的动态库 ,

参考 【错误记录】Android 应用执行报错 ( java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader) 博客 ,

如果要导入 arm64 架构的动态库 , 则需要导入

implementation 'tv.danmaku.ijk.media:ijkplayer-arm64:0.8.8'

动态库 , 则报如下错误 :

二、解决方案

---

在报错中 , 给出了 $2$ 种修改方案 :

	Suggestion: use a compatible library with a minSdk of at most 19,
		or increase this project's minSdk version to at least 21,
		or use tools:overrideLibrary="tv.danmaku.ijk.media.player_arm64" to force usage (may lead to runtime failures)

方案一

在 build.gradle 中配置 android # defaultConfig # minSdkVersion 为 $21$ ;

android {
    
    
    compileSdkVersion 30
    buildToolsVersion "29.0.2"

    defaultConfig {
    
    
        applicationId "com.example.app"
        minSdkVersion 19
    }
}

方案二

在 AndroidManifest.xml 中 , 配置

    <uses-sdk
        xmlns:tools="http://schemas.android.com/tools"
        tools:overrideLibrary="tv.danmaku.ijk.media.player_arm64"/>

标签 , 配置位置在 manifest 跟标签下 , 与 application 标签平级 ;

<?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.example.app"
    android:installLocation="auto">
    
    <uses-sdk
        xmlns:tools="http://schemas.android.com/tools"
        tools:overrideLibrary="tv.danmaku.ijk.media.player_arm64"/>

</manifest>
