我试图启用禁用蓝牙设备.出于这个原因,我写了下面的代码,但它给出了错误,也在下面.

if ( bluetoothadmin == null ) {    return ;}if ( bluetooth . isEnabled()){    bluetooth . disable ();}else {    bluetooth . enable();}

在创造

BLuetoothAdapter bluetooth = BluetoothAdapter.getDefaultAdapter() ;

在manisfest

<uses-permission    androID:name="androID.permission.BLUetoOTH" /><uses-permission    androID:name="androID.permission.BLUetoOTH_admin" />

错误：

01-23 07:18:53.167: E/BluetoothAdapter(883): Bluetooth binder is null

我在AndroID模拟器上测试

解决方法 模拟器不支持sdk的文档中提到的蓝牙.你必须在真实设备中检查这个..

你得到错误蓝牙绑定器是空的.这意味着模拟器没有蓝牙功能.
