问题描述
我最近正在创建一个使用蓝牙的应用程序.问题是,每当我启动蓝牙服务时,我的应用程序就会崩溃.这是我的清单文件
I was recently creating an app that uses bluetooth. The problem is my app crashes when ever I start the bluetooth service. Here's my manifest file
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="in.petalappstudio.fit" >
<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:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service
android:name=".bluetoothManager"
android:enabled="true"
android:exported="true">
</service>
</application>
现在您可以看到,我已经添加了蓝牙和蓝牙管理员的权限.
Now as you can see I have added permission for bluetooth and bluetooth admin.
我的应用程序为何崩溃并且在LOGCAT中错误是
How ever my app crashes and in LOGCAT the error is
"java.lang.RuntimeException: Unable to start service " and is caused by
"java.lang.SecurityException: Need BLUETOOTH ADMIN permission: Neither user 10145 nor current process has android.permission.BLUETOOTH_ADMIN."
但是您已经看到,我已经添加了权限.现在为什么会这样?
But I have added permission as you can see. Now why is this happening ?
推荐答案
尝试再添加一个权限:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
注意:也请检查设备是否支持蓝牙功能:
Note : also check device support Bluetooth feature or not using :
<uses-feature android:name="android.hardware.bluetooth" android:required="true" />
