Android端 拨打电话、视频通话、挂断电话，以及Uniapp调用的源码实现。

Android 拨打电话或视频通话函数

    private final String Tag = "callTel";
    
    @UniJSMethod(uiThread = false)
    public void callTel(JSONObject options,UniJSCallback callback){
        Log.e(Tag, "callTel");

        try{
            String tel = options.getString("tel");
            String callType = options.getString("callType");
            
            Context context = mUniSDKInstance.getContext();

            Intent intent = new Intent(Intent.ACTION_CALL);
            intent.setData(Uri.parse("tel:"+tel));

            //视频通话
            if(callType.equals("video")){
                intent.putExtra(TelecomManager.EXTRA_START_CALL_WITH_VIDEO_STATE, VideoProfile.STATE_BIDIRECTIONAL);
                intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            }


            ((Activity)context).startActivity(intent);

            Log.e(Tag, "callTel ok");

            if (callback != null) {
                JSONObject data = createCallbackData(success_code,success_text);
                callback.invoke(data);
            }
        }
        catch (Exception e){
            if(callback!=null) {
                JSONObject data = createCallbackData(fail_code, String.valueOf(e));
                callback.invoke(data);
            }
            Log.e(Tag, "Exception:"+e);
        }
    }

Android 挂断电话 函数

    @UniJSMethod(uiThread = false)
    public void endCall(UniJSCallback callback){
        Log.e(Tag, "endCall");
        Context context = mUniSDKInstance.getContext();
        try {


            TelephonyManager telManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
            Method method = telManager.getClass().getDeclaredMethod("endCall");
            method.invoke(telManager);

            if(callback!=null) {
                JSONObject data = createCallbackData(success_code, success_text);
                callback.invoke(data);
            }

            Log.e(Tag, "endCall ok");
        } catch (Exception e) {
            Log.e(Tag, "endCall Exception:"+e);
            if(callback!=null) {
                JSONObject data = createCallbackData(fail_code, String.valueOf(e));
                callback.invoke(data);
            }
        }

    }

UniApp手机端调用App原生语言插件

export function call (tel,callType){
	return new Promise((resolve)=>{
    // 引入 App 原生语言插件 PluginName 为原生插件名称
		const plugin = uni.requireNativePlugin('PluginName')
		// 判断引入情况
		if (!plugin) {
			uni.showToast({
				icon: 'none',
				title: '插件引入失败'
			})
			resolve({code:0,data:'插件引入失败'})
			return
		}
		
		plugin.callTel({tel,callType},(res) => {
			console.log('callTel：', res);
			resolve(res)
		})
	})
}

export function endCall (){
	console.log('endCall')
	return new Promise((resolve)=>{
		const plugin = uni.requireNativePlugin('PluginName')
		// 判断引入情况
		if (!plugin) {
			uni.showToast({
				icon: 'none',
				title: '插件引入失败'
			})
			resolve({code:0,data:'插件引入失败'})
			return
		}
		plugin.endCall((res) => {
			console.log('endCall：', res);
			resolve(res)
		})
	})
}
