I have been working on an app which needs to find some discoverable Bluetooth devices. I have followed guides and looked at answers on here and followed. However I cannot seem to get the phone to start scanning.
Here is the full activity code:
public class MainActivity extends AppCompatActivity {
private TextView scanningText;
private ListView scanningListView;
private Button scanningButton;
boolean scanComplete;
private final static int REQUEST_ENABLE_BT = 1;
private ArrayList<String> mDeviceList;
private BluetoothAdapter mBluetoothAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mDeviceList = new ArrayList<>();
scanningButton = (Button) findViewById(R.id.scanningButton);
scanningText = (TextView) findViewById(R.id.scanningText);
scanningListView = (ListView) findViewById(R.id.scanningList);
mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
if (mBluetoothAdapter == null) {
scanningText.setText("Your device does not support Bluetooth, Sorry!");
}
else if (!mBluetoothAdapter.isEnabled()) {
scanningText.setText("You need to enable bluetooth to use this app..");
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
}
// Register for broadcasts when a device is discovered.
IntentFilter filter = new IntentFilter(BluetoothDevice.ACTION_FOUND);
registerReceiver(mReceiver, filter);
scanningButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
scanningText.setText("Scanning...");
mBluetoothAdapter.startDiscovery();
}
});
}
#Override
protected void onDestroy() {
unregisterReceiver(mReceiver);
super.onDestroy();
}
private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (BluetoothDevice.ACTION_FOUND.equals(action)) {
BluetoothDevice device = intent
.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
mDeviceList.add(device.getName() + "\n" + device.getAddress());
Log.i("BT", device.getName() + "\n" + device.getAddress());
scanningListView.setAdapter(new ArrayAdapter<>(context,
android.R.layout.simple_list_item_1, mDeviceList));
}
else {
Log.i("BT", "none"+ "");
}
}
};
}
When I check the android log console, there are no logs.
Thanks
Update:
I have moved startDiscovery to the onclick listener.
Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();
if (pairedDevices.size() > 0) {
// There are paired devices. Get the name and address of each paired device.
for (BluetoothDevice device : pairedDevices) {
String deviceName = device.getName();
String deviceHardwareAddress = device.getAddress(); // MAC address
}
Log.i("found", pairedDevices + "");
}
The following check takes place when i press the scan button. I am told the device is not discovering by the toast.
scanningButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
scanningText.setText("Scanning...");
mBluetoothAdapter.startDiscovery();
if (mBluetoothAdapter.isDiscovering()) {
mBluetoothAdapter.isDiscovering();
Toast toast = Toast.makeText(getApplicationContext(), "discovering", Toast.LENGTH_LONG);
toast.show();
}
else {
Toast toast = Toast.makeText(getApplicationContext(), "not discovering", Toast.LENGTH_LONG);
toast.show();
}
}
});

Try adding those permissions in the manifest :
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
Also, it's always recommended to ask the user for permissions, so here you go :
if (Build.VERSION.SDK_INT >= 23 && ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);
}
if(Build.VERSION.SDK_INT >= 23 && ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, 1);
}
You should start by adding logs at every steps.
Log.i("TAG", "Message")
Does your manifest file contains the appropriate permissions?
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
Next, it seems like you do not check if the bluetooth is enabled on the device. You should use an intent to do so.
if (!mBluetoothAdapter.isEnabled()) {
Intent enableBT = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBT, REQUEST_BLUETOOTH);
}

In your xml layout try to check if the id of ScrollView is "scrollView", if not change it to scrollView the same as how you initialize in this line.
((ScrollView) findViewById(R.id.scrollView)).addView(listView);
or check your xml layout if ScrollView widget exist.
It throws the null pointer Exception because it cannot bind the layout, the id maybe misspelled or there is no scrollview widget in your layout.
Thank you everyone for your suggestion. The issue is solved. this code has two issue for which it did not work.
1. ((ScrollView) findViewById(R.id.scrollView)).addView(listView);
in this line scrollView is the wrong ID name. it should be the ID of your scrollview which for my case is device_list. it was making the app crash.
second issue is that i didnot call call for the permission function which will not give the list of BLE devices for android 6+ devices.
This question already has answers here:
What is a NullPointerException, and how do I fix it?

Closed 5 years ago.
I am a beginner at android studio, I have a mission to redesign the app. I use the Fragment. But when I run my app, it has stopped and there is no error in my Gradle. I looked for many website to solve my question, but still have no idea.
I have some questions below.
How can I fix the java.lang.RuntimeException (NULL Pointer Exception) ?

About Fragment. Is there any setting I have to do when I receive data form sever?
I want to put the received data to TextView in the another view .
Your init() function is probably try to find views inside fragments in view pager. However, at that moment, the fragments are not inflated yet, so your views in the activity are null and trying to do operation on them gives NPE. You should use onCreateView() of Fragment classes to find those views. Then you may notify main activity via callback mechanism.
For example, create FirstFragment as follows:
public class FirstFragment extends Fragment {
private OnFirstFragmentReadyListener callback;
#Override
public void onAttach(Context context) {
super.onAttach(context);
// This makes sure that the container activity has implemented the callback.
try {
callback = (OnFirstFragmentReadyListener) context;
} catch (ClassCastException e) {
throw new ClassCastException(context.toString()
+ " must implement OnFirstFragmentReadyListener");
}
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_first, container, false);
return rootView;
}
#Override
public void onActivityCreated(#Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
// Notify the parent activity that the fragment is inflated.
callback.onFirstFragmentReady();
}
public interface OnFirstFragmentReadyListener {
void onFirstFragmentReady();
}
}
Let the layout of FirstFragment as follows (referenced above as fragment_first):
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/first_label"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
Assume we created two more similar fragment classes named as SecondFragment and ThirdFragment. Then the activity should be like this:
public class MainActivity extends AppCompatActivity implements FirstFragment.OnFirstFragmentReadyListener,
SecondFragment.OnSecondFragmentReadyListener, ThirdFragment.OnThirdFragmentReadyListener {
...
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
viewPager =(ViewPager) findViewById(R.id.pager);
PagerAdapter pagerAdapter = new PagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(pagerAdapter);
// Don't call these functions here, spread them into callbacks.
// init();
// Action();
}
#Override
public void onFirstFragmentReady() {
TextView firstTextView = (TextView) findViewById(R.id.first_label);
...
// Now you have the views from FirstFragment instance.
// You can now call setText() or setOnClickListener() here.
}
#Override
public void onSecondFragmentReady() {
TextView secondTextView = (TextView) findViewById(R.id.second_label);
...
// Now you have the views from SecondFragment instance.
// You can now call setText() or setOnClickListener() here.
}
#Override
public void onThirdFragmentReady() {
TextView thirdTextView = (TextView) findViewById(R.id.third_label);
...
// Now you have the views from ThirdFragment instance.
// You can now call setText() or setOnClickListener() here.
}
}
Although this code works, this may not be the best way. I think it is better to do operations on views like setting texts or assigning OnClickListeners in fragments itself. If you need to notify a fragment after an action happened in the parent activity, you can implement public methods inside fragments and you can call them from the parent activity when needed.
In fragment you should call the function in onCreateView function(reason as mention by #Mehmed) which is something like below:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.your_fragment, container, false);
//all findViewById;
TextView yourTextView = (Text)view.findViewById(R.id.yourTextView);
//here call for your function
init();
// any other function goes here
return view;
}
So I am creating an app that requests permission to a users google account. I used mine to test and so I gave it permission and then removed it to see if it would ask for it again. It was still using the token it got so I deleted the app from my phone and reinstalled it. I didn't change any code and now all of a sudden it only shows the account page (to select which account) and then once I press ok, nothing shows to give it permission. In my run console I get the following:
$ adb push C:\Users\James Singleton\AndroidStudioProjects\ChffrAPI\app\build\outputs\apk\app-debug.apk /data/local/tmp/com.example.jamessingleton.chffrapi
$ adb shell pm install -r "/data/local/tmp/com.example.jamessingleton.chffrapi"
pkg: /data/local/tmp/com.example.jamessingleton.chffrapi

Nothing changed in my code so I have no idea why I am not getting the pop up to allow me to give the app permission.

I am having a problem with my Android Flashlight App. The app crashes when I try to press the home button of the device while the app is opened then resuming (by clicking the app icon on home screen not recent apps button). After I terminate the app from the recent apps list then opening again, it does not crash anymore using the same instructions above.
Please see code below.

Remove below line from onCreate and write it in onResume and it might not crash after doing so.

You need to enable geoLocation API from your google console and create a key and use that key in your app menifest like this :
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="YOUR_API_KEY"/>
also check for runtime permission for android M+
