How do you get the bluetooth MAC address android8.0, please!-CodePudding

A lot of search on the net, can under 8.0, but in not more than 8.0, is there anyone who knows!

CodePudding user response:

Reflection

 
Private String getBluetoothMacAddress () {
BluetoothAdapter BluetoothAdapter=BluetoothAdapter. GetDefaultAdapter (); 
String bluetoothMacAddress=""; 
If (android. OS. Build. VERSION. SDK_INT & gt;=android. OS. Build. VERSION_CODES. M) {
Try {
The Field mServiceField=bluetoothAdapter. GetClass (). GetDeclaredField (" mService "); 
MServiceField. SetAccessible (true); 

The Object btManagerService=mServiceField. Get (bluetoothAdapter); 

If (btManagerService!=null) {
BluetoothMacAddress=(String) btManagerService. GetClass () getMethod (" getAddress "). The invoke (btManagerService); 
} 
} the catch (NoSuchFieldException e) {

} the catch (NoSuchMethodException e) {

} the catch (IllegalAccessException e) {

} the catch (InvocationTargetException e) {

} 
} else {
BluetoothMacAddress=bluetoothAdapter. GetAddress (); 
} 
Return bluetoothMacAddress; 
}

Upstairs, 6.0 can be, but get less than 8.0, throw an exception

CodePudding user response:

Seems to make uncertain, I'm up for a long time

CodePudding user response:

What process?

If it is not reflection system apis abnormalities, see the GitHubhttps://github.com/tiann/FreeReflection

CodePudding user response:

references 4 floor wang can reply:

thrown exception?

If it is not abnormal reflection system apis, see the GitHubhttps://github.com/tiann/FreeReflection

Throw InvocationTargetException this exception, should not the reflection of the things,

Cut a figure out ah, drunk, you this is to ask questions

I was also a lot of trouble with this thing, give you some hints,
1. In Android8.1 Settings - & gt; The System - & gt; The About - & gt; The Status, & gt; In the Bluetooth address show, don't know if your version,
2. A careful look at the code is

 private void setBtStatus () {
BluetoothAdapter bluetooth=BluetoothAdapter. GetDefaultAdapter (); 
If (bluetooth!=null & amp; & MBtAddress!=null) {
String address=bluetooth. IsEnabled ()? Bluetooth. GetAddress () : null; 
if (! TextUtils. IsEmpty (address)) {
//Convert the address to lowercase for consistency with the wifi MAC address. 
MBtAddress. SetSummary (address. ToLowerCase ()); 
The e (" AHU. MAIN_ACTIVITY ", "address=" + address. ToLowerCase ()); 
} else {
MBtAddress. SetSummary (mUnavailable); 
} 
} 
}

Code in, vendor, mediatek, proprietary \ packages \ apps \ MtkSettings \ SRC \ com \ android \ Settings \ deviceinfo \ Status Java

You put with this code application system/priv - app/below can be obtained, and get in the same way as system, pay attention to the/system/pri - app, not the system/app

3. Can use the Settings. Secure. Get string (context. GetContentResolver (), "bluetooth_address"); Available, but you have to change the source code,
Add this MOVED_TO_GLOBAL. Add (Settings. Global. BLUETOOTH_ADDRESS); Can also,

You can give it a try,

What you said is the traditional bluetooth, are android and IOS also learned to hide the bluetooth address?

The building Lord, now resolved? My side is thrown directly InvocationTargetException this exception,
