这个错误是由于Android的BLE(Bluetooth Low Energy)库在处理HID(Human Interface Device)指示或通知时产生的警告。下面是解决这个问题的一种可能的方法:
implementation 'com.android.support:appcompat-v7:{your_appcompat_version}'
implementation 'com.android.support:support-v4:{your_support_version}'
private BluetoothAdapter mBluetoothAdapter;
private BluetoothGatt mBluetoothGatt;
// 初始化蓝牙适配器
BluetoothManager bluetoothManager = (BluetoothManager) getSystemService(Context.BLUETOOTH_SERVICE);
mBluetoothAdapter = bluetoothManager.getAdapter();
// 连接到设备
BluetoothDevice device = mBluetoothAdapter.getRemoteDevice(deviceAddress);
mBluetoothGatt = device.connectGatt(this, false, mGattCallback);
private final BluetoothGattCallback mGattCallback = new BluetoothGattCallback() {
@Override
public void onCharacteristicChanged(BluetoothGatt gatt, BluetoothGattCharacteristic characteristic) {
// 处理指示或通知
if (characteristic.getUuid().equals(YOUR_CHARACTERISTIC_UUID)) {
byte[] data = characteristic.getValue();
// 处理数据
}
}
};
通过以上步骤,你应该能够正确处理BLE指示或通知,并解决"Android BLE logcat错误:E/bt_btif: bta_gattc_process_indicate,忽略HID指示/通知"的问题。
