This is a demo of how to use the Android-BluetoothSPPLibrary to build a Bluetooth terminal with Android Studio 3.1.1
-
To get started, create a new project in the android studio with an Empty Activity template, set the Min API level to 18.
-
Under Gradle Scripts --> build.gradle(Module:app), append the line implementation 'com.akexorcist:bluetoothspp:1.0.0' to the end of dependencies.
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
implementation 'com.akexorcist:bluetoothspp:1.0.0'
}
- Declare permission for library: add the two lines below to the manifests --> AndroidManifest.xml,
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />- The AndroidManifest.xml should look like as below:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.wei.bluesppdemo">
<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
