• uniapp如何打开app,传递的值的

<template>
	<view class="content">
		<button type="default" @click="jsCallNativeActivity()">点击打开demo</button>
	</view>
</template>

<script>
	export default {
		data() {
			return {
				title: 'Hello'
			}
		},
		onLoad() {

		},
		methods: {
			jsCallNativeActivity() {
				let _this = this;
				// 判断平台  
				if (plus.os.name == 'Android') {
					plus.runtime.launchApplication({
							//这里输入包名
							pname: 'com.exaample.demo',
							//传值
							extra: {
								key: 123
							}
						},
						function(e) {
							console.log('Open system default browser failed: ' + e.message);
						}
					);
				} else if (plus.os.name == 'iOS') {
					plus.runtime.launchApplication({
						action: 'taobao://'
					}, function(e) {
						console.log('Open system default browser failed: ' + e.message);
					});
				}
			}
		}
	}
</script>

• 下面是安卓app 页面里如何接收的

package com.example.demo;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
import android.os.Bundle;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

    TextView textView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        textView = findViewById(R.id.tv);

        Intent intent = getIntent();

        StringBuffer sb = new StringBuffer();

        Bundle bundle = intent.getExtras();

        if (null == bundle) {
            textView.setText("bundle为空");
            return;
        }

        for (String key : bundle.keySet()) {
            sb.append(" key = ").append(key).append(" , value = ").append(bundle.get(key)).append(" ; ");
        }

        textView.setText(sb.toString());
    }
}
