Android蓝牙连接

我发布了一个问题，但还没有人回答。可能是我问错了。所以我在这里再次问

这里是我上一个问题的链接

问题: 为什么通过蓝牙从android连接到蓝牙设备时出现问题。 日志显示权限被拒绝。我在这里发布我的日志。我的设备与PC蓝牙终端配合良好，但当我尝试通过应用程序从手机连接设备时，它成功配对，但无法连接。是的，代码中没有问题，因为代码是由设备制造商提供的演示应用程序，并且在清单中也添加了适当的权限。。它是用安卓3.2测试的。而且效果很好。但我在android studio 2.3.1上配置了它，并提供了以下详细信息

android {
    compileSdkVersion 19
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "ixxat.adk.demo"
        minSdkVersion 13
        targetSdkVersion 19
        compileOptions {
            sourceCompatibility JavaVersion.VERSION_1_5
            targetCompatibility JavaVersion.VERSION_1_5
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
    productFlavors {
    }
}

显示清单文件please@VladMatvienko先生，我已经编辑了我的问题并在那里添加了清单。请看一看。@VladMatvienko请帮帮我，先生。我被这个问题困扰了5天。到目前为止，我没有看到任何问题。你试过哪些手机？@VladMatvienko LG G3和一款平板电脑ARCHOS 10，它们是我刚才提到的Android版本。我也不明白为什么它会给我这个错误。我在网上搜索了4天，但没有任何帮助(
