修改gradle如下

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    buildToolsVersion "29.0.2"
    defaultConfig {
        applicationId "com.uniapp.sample"
        minSdkVersion 19
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

    lintOptions {
        checkReleaseBuilds false
        abortOnError false
    }
    /*代码开始*/
    aaptOptions {
        additionalParameters '--auto-add-overlay'
        //noCompress 'foo', 'bar'
        ignoreAssetsPattern "!.svn:!.git:.*:!CVS:!thumbs.db:!picasa.ini:!*.scc:*~"
    }
    /*代码结束*/
}

repositories {
    flatDir {
        dirs 'libs'
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation fileTree(include: ['*.aar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:28.0.0'
    /*uniapp所需库-----------------------开始*/
    implementation 'com.android.support:recyclerview-v7:28.0.0'
    implementation 'com.facebook.fresco:fresco:1.13.0'
    implementation "com.facebook.fresco:animated-gif:1.13.0"
    /*uniapp所需库-----------------------结束*/
    // 基座需要，必须添加
    implementation 'com.github.bumptech.glide:glide:4.9.0'
    implementation 'com.alibaba:fastjson:1.1.46.android'
}

修改AndroidManifest.xml文件如下

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.uniapp.sample">
