android注册蓝牙广播无响应,uniappBroadcastReceiver广播监听无效，求解

最后还是弃用了&＃xff0c;因为监听接收消息的时候&＃xff0c;发现好像页面卡死了&＃xff0c;也不知道有啥好办法&＃xff0c;

搜索不到 我这边的原因是因为没有申请到动态权限&＃xff0c;代码如下

searchDevices() {

let BluetoothAdapter &＃61; plus.android.importClass("android.bluetooth.BluetoothAdapter");

let BluetoothDevice &＃61; plus.android.importClass("android.bluetooth.BluetoothDevice");

let BluetoothSocket &＃61; plus.android.importClass("android.bluetooth.BluetoothSocket");

let BluetoothReceiver &＃61; plus.android.importClass("android.bluetooth.BluetoothReceiver");

let Intent &＃61; plus.android.importClass("android.content.Intent");

let IntentFilter &＃61; plus.android.importClass("android.content.IntentFilter");

this.BAdapter &＃61; BluetoothAdapter.getDefaultAdapter();

//检查设备是否支持蓝牙

if (this.BAdapter &＃61;&＃61; null) {

uni.showToast({

title: "该设备不支持蓝牙",

duration: 2000,

icon: "none"

});

return false;

} else {

// 如果没有打开蓝牙

if (!this.BAdapter.isEnabled()) {

// 打开蓝牙操作

let startBt &＃61; new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);

console.log(startBt);

this.mainActivity.startActivityForResult(startBt, 1000);

// this.BAdapter.enable(); //打开蓝牙

// console.log(this.BAdapter.getAddress());

// console.log(this.BAdapter.getName());

} else {

// console.log(BAdapter.isDiscovering());

// 检测当前是否在搜索蓝牙

if (this.BAdapter.isDiscovering()) {

this.BAdapter.cancelDiscovery();

}

let IntentFilter &＃61; plus.android.importClass(&＃39;android.content.IntentFilter&＃39;);

let filter &＃61; new IntentFilter();

if (this.btFindReceiver !&＃61; null) {

try {

this.mainActivity.unregisterReceiver(this.btFindReceiver);

} catch (e) {

console.error(e);

}

this.btFindReceiver &＃61; null;

// this.BAdapter.cancelDiscovery();

}

// SDK

this.Build &＃61; plus.android.importClass("android.os.Build");

let Manifest &＃61; plus.android.importClass("android.Manifest");

// console.log(Build.VERSION.SDK_INT);

// if (Build.VERSION.SDK_INT >&＃61; 6.0) {}

let ArrPermissions &＃61; [

Manifest.permission.BLUETOOTH_ADMIN,

Manifest.permission.BLUETOOTH,

Manifest.permission.ACCESS_FINE_LOCATION,

Manifest.permission.ACCESS_COARSE_LOCATION

]

if (!this.PermissionChecks(ArrPermissions)) {

// 如果没有权限&＃xff0c;请求权限

this.PermissionRequest(ArrPermissions);

} else {

// 开始showtoast

uni.showLoading({

title: &＃39;蓝牙设备搜索中&＃39;,

mask: false

});

filter.addAction(BluetoothDevice.ACTION_FOUND); //发现蓝牙设备

filter.addAction(BluetoothDevice.ACTION_BOND_STATE_CHANGED); //蓝牙设备绑定状态改变

filter.addAction(BluetoothAdapter.ACTION_STATE_CHANGED); //蓝牙设备的状态改变

filter.addAction(BluetoothAdapter.ACTION_DISCOVERY_FINISHED); //搜索完成

//filter.addAction(BluetoothAdapter.ACTION_DISCOVERY_STARTED); //开始扫描

this.btFindReceiver &＃61; null;

let that1 &＃61; this;

this.devsList &＃61; [];

this.btFindReceiver &＃61; plus.android.implements(&＃39;io.dcloud.android.content.BroadcastReceiver&＃39;, {

onReceive: function(context, intent) { //实现onReceiver回调函数

console.log(&＃39;onReceive函数回调&＃39;);

plus.android.importClass(context);

plus.android.importClass(intent);

let action &＃61; intent.getAction();

if (BluetoothDevice.ACTION_FOUND &＃61;&＃61; action) { // 找到设备

};

that1.devsList.push(newDevice)

// console.log(plus.android.invoke(device, "getName"));

// that1.DiscoveryNewDevice(newDevice);

}

if (BluetoothAdapter.ACTION_DISCOVERY_FINISHED &＃61;&＃61; action) { // 搜索完成

console.log(&＃39;搜索完成&＃39;);

that1.BAdapter.cancelDiscovery();

uni.hideLoading();

uni.showToast({

});

}

console.log(&＃39;onReceive结束回调&＃39;);

}

});

this.mainActivity.registerReceiver(this.btFindReceiver, filter);

this.BAdapter.startDiscovery(); //开启搜索

}

}
