uniapp应用间实现通信,通过自定义广播实现

一、uniapp检测应用安装,并实现跳转至其他app

if (
			plus.runtime.isApplicationExist({
				//查看安卓系统手机有没有下载这款app
				pname: 'com.android.browser'//本地浏览器的包名
			})
		) {
			//安装了app则运行
			plus.runtime.launchApplication({
						pname: "com.android.browser",
						action: "com.android.browser.BrowserActivity",
					}, (e) => {
						console.log("e", e)
					})
		} else {
			//未安装app
			uni.showModal({
				title: '提示',
				content: '您还没有此APP,去下载',
				success: function(res) {
					if (res.confirm) {
						plus.runtime.openURL('https://a.app.qq.com/o/simple.jsp?pkgname=com.tencent.mm', function(res) {
							console.log(res);
						});
					} elseif (res.cancel) {
						console.log('用户点击取消');
					}
				}
			});
		}

注意: 实现跳转的过程中,携带参数的方式如下

let senddata = {"uid":136523,"username":"dy13","nickname":"缎玉13","mobile":"","email":"[email protected]","avatar":null}
				//调用第三方app
				plus.runtime.launchApplication({
						pname: "io.dcloud.HBuilder",
						action: "io.dcloud.PandoraEntry",
						extra: senddata //传递的参数
					},
					(e)=> {
						uni.showToast({
							title: "打开失败",
							icon: "none"
						})
					},
				);

二、自定义广播

1、发送广播

varIntent = plus.android.importClass("android.content.Intent");
var intent = newIntent("comxxx.xxx.appxxx");	// 要给发送广播应用的包名var keyValue = "要传递的值";
main = plus.android.runtimeMainActivity();  
intent.putExtra("data", keyValue);
main.sendBroadcast(intent);

2、接收广播

main = plus.android.runtimeMainActivity(); //获取activity//创建自定义广播实例  console.log('========main===', main)
receiver = plus.android.implements('io.dcloud.feature.internal.reflect.BroadcastReceiver', {
	onReceive: function(context, intent) { //实现onReceiver回调函数  
		plus.android.importClass(intent); //通过intent实例引入intent类,方便以后的‘.’操作  
		var action = intent.getAction()
		let code = intent.getStringExtra("data")
		console.log('--------context====', context)
		console.log('--------intent====', intent)
		console.log('--------action====', action)
		console.log('--------code====', code)
		if (action == 'com.android.browser') {
			console.log('监听扫码触发....')
			//条码或二维码
			var data = intent.getExtra("data");
			if (data) {
				console.log('zhanglp', data.replace(/\n/, ''))
				console.log('zhanglp', data.replace(/\n/, '').replace(/\t/, ''))
				success({
					type: 'barcode',
					data: data.replace(/\n/, '').replace(/\t/, '').trim() //处理结束符和换行符为空
				})
			} else {
				fail('未识别到扫码数据')
			}
		}
	}
});
varIntentFilter = plus.android.importClass('android.content.IntentFilter'); //网络varIntent = plus.android.importClass('android.content.Intent');
var filter = newIntentFilter(); //过滤
filter.addAction("comxxx.xxx.appxxx"); //监听 	此处的包名为发送广播app的包名/* filter.addAction(Intent.ACTION_AIRPLANE_MODE_CHANGED); //监听飞行模式 
filter.addAction("zeji.shanghai.scanner.RFID"); //监听rfid     
filter.addAction("zeji.shanghai.scanner.barcode"); //监听barcode
filter.addAction("com.scanner.broadcast"); //监听bar
var BluetoothAdapter = plus.android.importClass("android.bluetooth.BluetoothAdapter"); //蓝牙
var BAdapter = new BluetoothAdapter.getDefaultAdapter();
filter.addAction(BAdapter.ACTION_STATE_CHANGED); //监听蓝牙 */
main.registerReceiver(receiver, filter); //注册监听

注意:发送和接收中用到的变量main 和 receiver为全局变量,此处省略了定义

3、自定义广播示例

定义main 和receiver变量

// 测试唤醒其他appwakeOtherApp() {
	const isApp = plus.runtime.isApplicationExist({
		pname: 'qd.app'
	})
	if (isApp) {
		//已安装
		uni.showToast({
			title: '应用已安装',
			icon: 'success',
			duration: 3000
		})
		// plus.runtime.launchApplication({
		// 	pname: "com.android.browser",
		// 	action: "com.android.browser.BrowserActivity",
		// }, (e) => {
		// 	console.log("e", e)
		// })
	} else {
		// 没有安装
		uni.showToast({
			title: '应用未安装',
			icon: 'error',
			duration: 3000
		})
	}
	varIntent = plus.android.importClass("android.content.Intent");
	var intent = newIntent("qd.app");
	var keyValue = "要传递的值";
	// main = plus.android.runtimeMainActivity();  
	intent.putExtra("data", keyValue);
	main.sendBroadcast(intent);
},
//  接收广播recive(success, fail) {
	main = plus.android.runtimeMainActivity(); //获取activity
	//创建自定义广播实例  
	console.log('========main===', main)
	receiver = plus.android.implements('io.dcloud.feature.internal.reflect.BroadcastReceiver', {
		onReceive: function(context, intent) { //实现onReceiver回调函数  
			plus.android.importClass(intent); //通过intent实例引入intent类,方便以后的‘.’操作  
			var action = intent.getAction()
			let code = intent.getStringExtra("data")
			console.log('--------context====', context)
			console.log('--------intent====', intent)
			console.log('--------action====', action)
			console.log('--------code====', code)
			if (action == 'com.android.browser') {
				console.log('监听扫码触发....')
				//条码或二维码
				var data = intent.getExtra("data");
				if (data) {
					console.log('zhanglp', data.replace(/\n/, ''))
					console.log('zhanglp', data.replace(/\n/, '').replace(/\t/, ''))
					success({
						type: 'barcode',
						data: data.replace(/\n/, '').replace(/\t/, '').trim() //处理结束符和换行符为空
					})
				} else {
					fail('未识别到扫码数据')
				}
			}
		}
	});
	varIntentFilter = plus.android.importClass('android.content.IntentFilter'); //网络
	// var Intent = plus.android.importClass('android.content.Intent');
	var filter = newIntentFilter(); //过滤
	filter.addAction("qd.app"); //监听
	/* filter.addAction(Intent.ACTION_AIRPLANE_MODE_CHANGED); //监听飞行模式

	filter.addAction("com.scanner.broadcast"); //监听bar
	var BluetoothAdapter = plus.android.importClass("android.bluetooth.BluetoothAdapter"); //蓝牙
	var BAdapter = new BluetoothAdapter.getDefaultAdapter();
	filter.addAction(BAdapter.ACTION_STATE_CHANGED); //监听蓝牙 */
	main.registerReceiver(receiver, filter); //注册监听
}
