我试图过滤掉显示 USB 连接对话框的某些设备，并根据我的理解，可以通过创建设备筛选器、指定要允许的设备，然后在我的活动中处理意图来完成。
我遇到的问题是无论我连接什么设备，它都会提示（它不限制在 device_filter.xml 中的列表中）。
如何将连接提示限制为 device_filter.xml 中列出的设备？
device_filter.xml:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<usb-device vendor-id="1027" product-id="24597">
<usb-device vendor-id="1659" product-id="8963" >
</resources>
此文件包含我希望列入白名单的设备。
来自 AndroidManifest.xml:
<activity
android:name=".Player"
android:clearTaskOnLaunch="true"
android:configChanges="orientation|keyboardHidden"
android:exported="true"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />
</intent-filter>
<meta-data
android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED"
android:resource="@xml/device_filter" />
</activity>
在我的活动中：
if (intent.getAction() != null){
if (intent.getAction().equals(UsbManager.ACTION_USB_DEVICE_ATTACHED)) {
Context context = getApplicationContext();
try
{
PackageManager pm = context.getPackageManager();
ApplicationInfo ai = pm.getApplicationInfo( "com.package.name", 0 );
if( ai != null )
{
UsbManager manager = (UsbManager) context.getSystemService( Context.USB_SERVICE );
IBinder b = ServiceManager.getService( Context.USB_SERVICE );
IUsbManager service = IUsbManager.Stub.asInterface( b );
HashMap<String, UsbDevice> deviceList = manager.getDeviceList();
Iterator<UsbDevice> deviceIterator = deviceList.values().iterator();
while( deviceIterator.hasNext() )
{
UsbDevice device = deviceIterator.next();
Log.d ("DERP", "The Vendor ID is: "+device.getVendorId());
Log.d ("DERP", "The interface is: "+device.getInterfaceCount());
//service.grantDevicePermission( device, ai.uid );
//service.setDevicePackage( device, "com.package.name");
}
}
}
catch( Exception e )
{
e.printStackTrace();
}
}
}
