Need example android Bluetooth permission code

I need an example java code of Bluetooth permissions. Android 12.
I know that I have to put this in the AndroidManifest.xml
<uses-permission android:name="android.permission.BLUETOOTH"/>
From my research I think I have to use these tools to get my phone to ask me for Bluetooth permissions:
ActivityCompat
ContextCompat
PackageManager
onRequestPermissionsResult
But no luck after many hours of tests.
I even tried using libraries from GitHub to ask for "easy" permissions for me but no luck:
https://github.com/googlesamples/easypermissions
https://github.com/guolindev/PermissionX
I tried lowering my target SDK version so I don't need to ask for the user entry but "AndroidX" gave me an error telling that its not compatible with lower SDK's.
It would help me a ton if you have a basic working Bluetooth app java code so I can figure out how to code my own app.

For the new Bluetooth permissions on Android 12, you need these permissions:
<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
<uses-permission android:name="android.permission.BLUETOOTH_SCAN" />
You can refer to this blog post for more details.

For bluetooth permission on Android 12, you need these permission, depend on your usage:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.NFC" />
<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
<uses-permission android:name="android.permission.BLUETOOTH_SCAN" />
<uses-feature android:name="android.hardware.nfc" android:required="true" />
<uses-feature android:name="android.hardware.bluetooth_le" android:required="true" />
In your activity, you can add this to check the permission is allowed or not:
private static final int ACCESS_COARSE_LOCATION_RESULT_CODE = 4;
private static final int BLUETOOTH_RESULT_CODE = 5;
private static final int DANGEROUS_RESULT_CODE = 1;
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.ACCESS_COARSE_LOCATION},
ACCESS_COARSE_LOCATION_RESULT_CODE);
}
else if (ContextCompat.checkSelfPermission(this,
Manifest.permission.BLUETOOTH) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.BLUETOOTH},
BLUETOOTH_RESULT_CODE);
}
else if(ContextCompat.checkSelfPermission(this,
Manifest.permission.BLUETOOTH_SCAN) != PackageManager.PERMISSION_GRANTED){
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.BLUETOOTH_SCAN},
DANGEROUS_RESULT_CODE);
}
}
else if(ContextCompat.checkSelfPermission(this,
Manifest.permission.BLUETOOTH_CONNECT) != PackageManager.PERMISSION_GRANTED){
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.BLUETOOTH_CONNECT},
DANGEROUS_RESULT_CODE);
}
}
To understand more, you can check the documentation.

"Required permission was denied!" when requesting WRITE_EXTERNAL_STORAGE

I am trying to request WRITE_EXTERNAL_STORAGE permission on Android 10. I do that using the following code:
ArrayList<String> permissions = new ArrayList<>();
if (this.checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
permissions.add(Manifest.permission.ACCESS_FINE_LOCATION);
}
if (this.checkSelfPermission(ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
permissions.add(Manifest.permission.ACCESS_COARSE_LOCATION);
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q &&
this.checkSelfPermission(ACCESS_BACKGROUND_LOCATION) != PackageManager.PERMISSION_GRANTED) {
permissions.add(Manifest.permission.ACCESS_BACKGROUND_LOCATION);
}
if (this.checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
permissions.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);
}
if (permissions.size() > 0) requestPermissions(permissions.toArray(new String[0]), PERMISSION_REQUEST_FINE_LOCATION);
Here is the manifest
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
All other permissions work except WRITE_EXTERNAL_STORAGE. When I try to request it, it does not display any dialog for confirming permission, but it simply denies it. Why and how can I fix it?

I have discovered the solution, however the cause of the problem is still a mystery to me. If anyone has an explination, it would be greatly appreciated. Basically my issue is a duplicate of this issue. All I had to do is to change the following line from
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
to
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" tools:node="replace"/>
What does tools:node="replace" do?

You can handle requested permission using this method (works with android 10), Here is the documentation.
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
switch (requestCode) {
case PERMISSION_REQUEST_ID_STORAGE:
// permisstion granted by user
break;
}
} else {
switch (requestCode) {
case PERMISSION_REQUEST_ID_STORAGE:
// permission denied by user
break;
}
}
}

You can use Android Runtime Permission Library by nabinbhandari
in you build.gradle app module file write this
//Android Runtime Permission Library
implementation 'com.nabinbhandari.android:permissions:3.8'
In your Manifest file write
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
and in Activity declare these variables
String[] permissions = new String[]{READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE};
String rationale = "Please provide storage permission to proceed ...";
And in your onCreate() Method write this
Permissions.Options options = new Permissions.Options()
.setRationaleDialogTitle("Info")
.setSettingsDialogTitle("Warning");
Permissions.check(MainActivity.this, permissions, rationale, options, new PermissionHandler() {
#Override
public void onGranted() {
// do your task.
Toast.makeText(MainActivity.this, "Permissions granted", Toast.LENGTH_SHORT).show();
}
#Override
public void onDenied(Context context, ArrayList<String> deniedPermissions) {
// permission denied
Toast.makeText(MainActivity.this, "Permissions denied", Toast.LENGTH_SHORT).show();
}
});

Problem After Permission Change in Publish App

I have a android app in play store. That has only internet permission. Now I change in app user can use their camera & storage.
I add privacy policy on play store and in link in app also. I also mention these permission in release text.
When I upload new app display message like this
minSdkVersion 21
targetSdkVersion 28
versionCode 4
versionName "4.0"
Permissions
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET"/>
<uses-feature android:name="android.hardware.camera2.full" />
<uses-feature android:name="android.hardware.camera.autofocus" />
Permission Code
private void permission(){
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED || ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(StartActivity.this, new String[]{Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE}, REQUEST_CAMERA_PERMISSION);
//Display_Rermission_Reason();
}else {
Intent intent = new Intent(StartActivity.this, PrivacyPolicyActivity.class);
startActivity(intent);
}
}
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
if (requestCode == REQUEST_CAMERA_PERMISSION) {
if (grantResults[0] == PackageManager.PERMISSION_DENIED) {
// close the app
Toast.makeText(MainActivity.this, "Sorry!!!, you can't use this app without granting permission", Toast.LENGTH_LONG).show();
//Display_Rermission_Reason();
}
}
}
After publish the app it display in google play store
This app is incompatible with all of your devices.
Any version 5+ and above

Change this in manifest,
<uses-feature android:name="android.hardware.camera2.full"
android:required="false" />
<uses-feature android:name="android.hardware.camera.autofocus"
android:required="false" />

missing permissions required by BluetoothAdapter.isEnabled.BLUETOOTH

I add bluetooth to my app but am running into the following problem. When I do the code:
BluetoothAdapter bluetoothAdapter=BluetoothAdapter.getDefaultAdapter();
if (bluetoothAdapter == null) {
Toast.makeText(getApplicationContext(),"Device doesnt Support Bluetooth",Toast.LENGTH_SHORT).show();
}
if(!bluetoothAdapter.isEnabled()) {
Intent enableAdapter = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableAdapter, 0);
}
The error is on the following line:
if(!bluetoothAdapter.isEnabled())
Error:
Missing permissions required by BluetoothAdapter.isEnabled :android.permissions.BLUETOOTH
I added the following permissions to the android manifest file:
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<permission android:name="android.permission.BLUETOOTH" android:label="BLUETOOTH" />
<permission android:name="android.permission.BLUETOOTH_ADMIN" />
but am still getting the same issue. Do you know what I did wrong?

You only need <uses-permission> tag since you are using a permission. You don't need <permissions> tag since this is not your custom permission.
Maybe you have placed <uses-permission> tag in the wrong element in manifest, but I cannot say anything else with the information you provided
Since your bluetoothAdapter can be null, either add to second IF null pointer check, or add a RETURN in first IF
It is also nice to have <uses-feature> tag

Let's say you have a button and then you click on it, Bluetooth needs to turn on. Here's a quick example how you would do it for Android 6.0 and above.
First, declare this variable in your Activity/Fragment:
public static final int PERMISSION_ASK = 1001;
Now, let's say this buttons is going to enable the bluetooth.
setOnClickListener:
myButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if(isBluetoothPermissionGranted()) {
// app already has required permissions
// do some task here
} else {
// app does not have permission yet.
// ask for permissions
askForBluetoothPermissions();
}
} else {
// Android version below 6.0, no need to check or ask for permission
// do some task here
}
}
});
Checking if application already has the required permission:
#RequiresApi(api = Build.VERSION_CODES.M)
private boolean isBluetoothPermissionGranted() {
boolean granted = false;
int bluetoothGranted = checkSelfPermission(Manifest.permission.BLUETOOTH);
int bluetoothAdminGranted = checkSelfPermission(Manifest.permission.BLUETOOTH_ADMIN);
if(bluetoothGranted == PackageManager.PERMISSION_GRANTED &&
bluetoothAdminGranted == PackageManager.PERMISSION_GRANTED) {
granted = true;
}
return granted;
}
If required permission is not granted, here's how you would ask for it:
#RequiresApi(api = Build.VERSION_CODES.M)
private void askForBluetoothPermissions() {
String[] permissions = new String[] {
Manifest.permission.BLUETOOTH,
Manifest.permission.BLUETOOTH_ADMIN
};
requestPermissions(permissions, PERMISSION_ASK);
}
And finally, here's how you would confirm if the user granted you the permission(s) or not:
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
switch (requestCode) {
case PERMISSION_ASK:
if(grantResults[0] == PackageManager.PERMISSION_GRANTED && grantResults[1] == PackageManager.PERMISSION_GRANTED) {
// all requested permissions were granted
// perform your task here
} else {
// permissions not granted
// DO NOT PERFORM THE TASK, it will fail/crash
}
break;
default:
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
break;
}
}
Hope this helps

For Android 6.0 and above you must add the following to manifest file
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<permission android:name="android.permission.BLUETOOTH" android:label="BLUETOOTH" />
<permission android:name="android.permission.BLUETOOTH_ADMIN" />
<permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

ACCESS_FINE_LOCATION AndroidManifest Permissions Not Being Granted

I am trying to utilize GPS in Android (2.2 and 2.3) but am getting the following error when I try to use the LocationManager object:
WARN/System.err(522): java.lang.SecurityException: Provider network requires ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION permission
I have researched the issue in other posts and they are typically due to issues with AndroidManifest.xml. However, mine appears to be fine:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.thedigitalsean.examples"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".GetLocation"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-permission android:name="android.permisssion.ACCESS_FINE_LOCATION"></uses-permission>
<uses-permission android:name="android.permisssion.ACCESS_COARSE_LOCATION"></uses-permission>
<uses-permission android:name="android.permisssion.INTERNET"></uses-permission>
</manifest>
Here is the offending line of code in my onCreate method in the GetLocation Activity, encased in a try/catch block:
LocationManager locManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
final LocationListener locListener = new MyLocListener();
try{
locManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locListener);
}
catch (SecurityException se){
((TextView)findViewById(R.id.infobox)).setText(se.toString());
se.printStackTrace();
}
This is the first app I have written where I need to request android permissions and have so far been unsuccessful in being granted any permissions whatsoever. Is there something I am missing in my manifest or perhaps in my eclipse configuration?

You misspelled permission
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

I was having the same problem and could not figure out what I was doing wrong. Turns out, the auto-complete for Android Studio was changing the text to either all caps or all lower case (depending on whether I typed in upper case or lower cast words before the auto-complete). The OS was not registering the name due to this issue and I would get the error regarding a missing permission. As stated above, ensure your permissions are labeled correctly:
Correct:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
Incorrect:
<uses-permission android:name="ANDROID.PERMISSION.ACCESS_FINE_LOCATION" />
Incorrect:
<uses-permission android:name="android.permission.access_fine_location" />
Though this may seem trivial, its easy to overlook.
If there is some setting to make permissions non-case-sensitive, please add a comment with the instructions. Thank you!

Compatible with all SDK versions (android.permission.ACCESS_FINE_LOCATION became dangerous permission in Android M and requires user to manually grant it).
In Android versions below Android M ContextCompat.checkSelfPermission(...) always returns true if you add these permission(s) in AndroidManifest.xml)
public void onSomeButtonClick() {
...
if (!permissionsGranted()) {
ActivityCompat.requestPermissions(this, new String[] {Manifest.permission.ACCESS_FINE_LOCATION}, 123);
} else doLocationAccessRelatedJob();
...
}
private Boolean permissionsGranted() {
return ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED);
}
#Override
public void onRequestPermissionsResult(final int requestCode, #NonNull final String[] permissions, #NonNull final int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == 123) {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// Permission granted.
doLocationAccessRelatedJob();
} else {
// User refused to grant permission. You can add AlertDialog here
Toast.makeText(this, "You didn't give permission to access device location", Toast.LENGTH_LONG).show();
startInstalledAppDetailsActivity();
}
}
}
private void startInstalledAppDetailsActivity() {
Intent i = new Intent();
i.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
i.addCategory(Intent.CATEGORY_DEFAULT);
i.setData(Uri.parse("package:" + getPackageName()));
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);
}
in AndroidManifest.xml:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

I Had an strange issue and realized that the text of manifest permission has a a space character at the end. removed it and it is working just fine.
Before
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION "/>
After
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

just remove s from the permission you are using sss you have to use ss
