uniapp android 原生插件封装--入门篇

本文将介绍uniapp 插件封装官方例子的搭建，运行。和注意事项，避坑

1、文档地址：简介 | uni小程序SDK

开发者须知 | uni小程序SDK

Android平台第三方插件开发指导 - DCloud问答这个介绍插件与原生的架构

2、下载官方示例：百度网盘请输入提取码 : jrrb

3、下载最新的 android sdk .2023-3-1

编译项目：

这个版本默认的SDK是17，官方的例子是旧项目。会提示sdkb版本太高，需要如下设置：把sdk改为你本机的1.8

3、代码需要添加gradle 配置：uniplugin_richalert ->build.gradle


dependencies {
    implementation 'androidx.test.ext:junit:1.1.5'
    compileOnly fileTree(dir: 'libs', include: ['*.jar'])

    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test:rules:1.0.2'

    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

    androidTestImplementation 'androidx.test:runner:1.4.0'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'



    testImplementation 'junit:junit:4.12'

    compileOnly 'androidx.recyclerview:recyclerview:1.0.0'
    compileOnly 'androidx.legacy:legacy-support-v4:1.0.0'
    compileOnly 'androidx.appcompat:appcompat:1.0.0'
    compileOnly 'com.alibaba:fastjson:1.2.83'

    compileOnly fileTree(dir: '../app/libs', include: ['uniapp-v8-release.aar'])

    compileOnly 'com.alibaba:fastjson:1.1.46.android'
}

uni.dcloud.io.uniplugin_richalert.ExampleInstrumentedTest.java 这个代码修改：

package uni.dcloud.io.uniplugin_richalert;

import android.content.Context;

import androidx.test.ext.junit.runners.AndroidJUnit4;
import androidx.test.platform.app.InstrumentationRegistry;

import org.junit.Test;
import org.junit.runner.RunWith;

import static org.junit.Assert.assertEquals;

/**
 * Instrumented test, which will execute on an Android device.
 *
 * @see <a href="http://d.android.com/tools/testing">Testing documentation</a>
 */
@RunWith(AndroidJUnit4.class)
public class ExampleInstrumentedTest {
    @Test
    public void useAppContext() {

        // Context of the app under test.
        Context appContext = InstrumentationRegistry.getInstrumentation().getTargetContext();

        assertEquals("uni.dcloud.io.uniplugin_richalert.test", appContext.getPackageName());
    }
}

到这步，编译可以通过了。
