大家好，又见面了，我是你们的朋友全栈君。

static {
		System.loadLibrary("serial_port");
	}

今天想连接串口做一个新功能但是连接串口加载库的时候总是找不到serial_port库

Android 加载串口通信读取信息时 AndroidStudio loadLibrary失败「建议收藏」

项目结构是这样的

库文件不多说 github很多

Android.mk

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

TARGET_PLATFORM := android-3

LOCAL_MODULE    := serial_port
LOCAL_SRC_FILES := SerialPort.c


#LOCAL_MODULE    := serial_port
#LOCAL_SRC_FILES := SerialPort.c
LOCAL_LDLIBS    := -llog

include $(BUILD_SHARED_LIBRARY)

但是写完Android.mk为什么还是不识别呢？

这是什么原因造成的呢？

要加上这句话

我项目中的库文件是build.gradle

apply plugin: 'com.android.library'

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.3"

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        consumerProguardFiles 'consumer-rules.pro'
    }
    sourceSets {
        main {
            jniLibs.srcDirs = ['libs']
        }
    }


        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            }
        }
    

    }

    dependencies {
        api fileTree(dir: 'libs', include: ['*.jar'])
        api fileTree(include: '*.jar', dir: 'libs')
        implementation 'androidx.appcompat:appcompat:1.1.0'
        testImplementation 'junit:junit:4.12'
        androidTestImplementation 'androidx.test.ext:junit:1.1.1'
        androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    }

    repositories {
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
