Hi, Iam new to android development I want to enable bluetooth in my app. I followed the android developer tutorial in the link https://developer.android.com/guide/topics/connectivity/bluetooth.html <https://developer.android.com/guide/topics/connectivity/bluetooth.html> I had used "BluetoothAdapter mBluetoothAdapter = BluetoothAdapter. getDefaultAdapter();" to get the bluetooth adapter when i try to check Bluetooth is supported using the commands if (mBluetoothAdapter == null) { // Device does not support Bluetooth }
Iam getting error "unknown class" for mBluetoothAdapter Also unable to check mBluetoothAdapter.isEnabled(); mBluetoothAdapter and its methods are not supported. My objective is to enable ble device and connect and pair with visible device and to send and receive data. Looking forward for support My code in MainActivity.java is package com.example.rd2_6.myfirstapp; import android.bluetooth.BluetoothAdapter; import android.bluetooth.BluetoothDevice; import android.bluetooth.BluetoothManager; import android.content.Context; import android.content.Intent; import android.content.pm.PackageManager; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.EditText; import android.widget.Toast; public class MainActivity extends AppCompatActivity { public final static String EXTRA_MESSAGE = "com.example.myfirstapp.MESSAGE"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter(); if(mBluetoothAdapter == null) { } // if (!mBluetoothAdapter.isEnable()) { // Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE); // startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT); // } public void sendMessage(View view) { // Intent intent = new Intent(this, DisplayMessageActivity.class); //EditText editText = (EditText) findViewById(R.id.edit_message); //String message = editText.getText().toString(); // intent.putExtra(EXTRA_MESSAGE, message); // startActivity(intent); } } with Thanks Jagdish -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
