Why is my runtime dangerous permission auto denied? - android

I am trying to use the "new" way of requesting external storage write permission.
But the request is automatically denied and no window pops up asking the user for permission.
Virtual Device: Pixel 2 API 30
SDK 30
I did add the permissions into the manifest file
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.lab6">
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE "/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<application
android:allowBackup="true"
WRITE_EXTERNAL_STORAGE is a dangerous permission from my knowledge, so it has to be requested at runtime.
into my gradle dependencies I added these:
implementation 'androidx.activity:activity:1.2.0'
implementation 'androidx.fragment:fragment:1.3.0'
The activity looks like this:
public class MainActivity extends AppCompatActivity {
private ActivityResultLauncher<String> requestPermissionLauncher =
registerForActivityResult(new ActivityResultContracts.RequestPermission(), isGranted -> {
if (isGranted) {
Log.d("mihai", "Permission is granted now.");
} else {
Log.d("mihai", "Permission refused ");
}
});
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button downloadBtn = findViewById(R.id.downloadButton);
Button loadBtn = findViewById(R.id.loadButton);
downloadBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Log.d("mihai", "requesting permission");
if (ContextCompat.checkSelfPermission(
getApplicationContext(), Manifest.permission.WRITE_EXTERNAL_STORAGE) ==
PackageManager.PERMISSION_GRANTED) {
Log.d("mihai", "permission already granted");
} else {
Log.d("mihai", "launching");
requestPermissionLauncher.launch(
Manifest.permission.WRITE_EXTERNAL_STORAGE);
}
}
});
}
}
And these are the logs I get. As you can see, the request is denied. No question pops up on the phone.
2022-04-28 19:55:15.351 7499-7499/com.example.lab6 D/mihai: requesting permission
2022-04-28 19:55:15.353 7499-7499/com.example.lab6 D/mihai: launching
2022-04-28 19:55:15.592 7499-7499/com.example.lab6 D/mihai: Permission refused

Because you have denied the permission multiple times.
From the documentation:
Starting in Android 11 (API level 30), if the user taps Deny for a specific permission more than once during your app's lifetime of installation on a device, the user doesn't see the system permissions dialog if your app requests that permission again. The user's action implies "don't ask again." On previous versions, users would see the system permissions dialog each time your app requested a permission, unless the user had previously selected a "don't ask again" checkbox or option.
You will need to redirect the user to the app's setting detail to grant the permission manually.
To open an app specific app's detail setting screen:
Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
intent.setData(Uri.parse("package:" + getPackageName()));
startActivity(intent);

Asking fine location permission

I want to access fine location from within my app and, for this, I declare an ActivityResultLauncherwith :
protected final ActivityResultLauncher<String[]> l = registerForActivityResult(new ActivityResultContracts.RequestMultiplePermissions(), isGranted -> {
if (isGranted .get(Manifest.permission.ACCESS_COARSE_LOCATION) & isGranted .get(Manifest.permission.ACCESS_FINE_LOCATION)) {
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 0, positionChangesListener);
} else {
Toast.makeText(this, getResources().getText(R.string.PermissionNotAllowed), Toast.LENGTH_LONG).show()
finish();
}
});
When I want to ask for this permission, I use :
l.launch(new String [] {Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION});
Unfortunately, the panel asking the user to grant permission doesn't show up. This doesn't prevent the callback from being executed, but with permissions denied. My app then immediatly stops, informing the user it can't continue to work if fine location permission isn't granted.
Any idea which could solve my problem?
wait where are asking for permission shouldn't it be in else ? after that have you added <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> and <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
in your manifest

How to re-request BLUETOOTH_SCAN and BLUETOOTH_CONNECT permissions for Android 12 after a user denial?

I have a problem re-requesting the permissions required to scan and connect to bluetooth devices when targeting SDK 31 (Android 12).
I call this method inside my main activity's onCreate():
public void requestBluetoothPermissions() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
if ((this.checkSelfPermission(Manifest.permission.BLUETOOTH_SCAN) != PackageManager.PERMISSION_GRANTED)
|| (this.checkSelfPermission(Manifest.permission.BLUETOOTH_CONNECT) != PackageManager.PERMISSION_GRANTED)) {
Log.w(getClass().getName(), "requestBluetoothPermissions() BLUETOOTH_SCAN AND BLUETOOTH_CONNECT permissions needed => requesting them...");
this.requestPermissions(new String[]{
Manifest.permission.BLUETOOTH_SCAN, Manifest.permission.BLUETOOTH_CONNECT
}, MyActivity.REQUEST_BLUETOOTH_PERMISSIONS);
}
}
}
It's works fine the first time it is called i.e. an Android pop-up is displayed to the user, prompting him to grant the permissions.
But if he refuses to grant the permissions, next time onCreate() is called, the pop-up will not be displayed, which means the user remains unable to grant the permissions.
Any idea why and how to fix this ?
It appears Android 12 blocks requesting the same permission after user denied it once only.
Therefore, I ended up using ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), Manifest.permission.BLUETOOTH_SCAN) to determine wether the permission can be requested or not, in which case a snackbar message is displayed explaining why is the permission needed, with a button opening the app settings where permission can be granted.
Here is a sample of the code:
public void requestBluetoothPermissions() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
if ((this.checkSelfPermission(Manifest.permission.BLUETOOTH_SCAN) != PackageManager.PERMISSION_GRANTED)
|| (this.checkSelfPermission(Manifest.permission.BLUETOOTH_CONNECT) != PackageManager.PERMISSION_GRANTED)) {
if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(),
Manifest.permission.BLUETOOTH_SCAN)) {
// display permission rationale in snackbar message
} else {
Log.w(getClass().getName(), "requestBluetoothPermissions() BLUETOOTH_SCAN AND BLUETOOTH_CONNECT permissions needed => requesting them...");
this.requestPermissions(new String[]{
Manifest.permission.BLUETOOTH_SCAN, Manifest.permission.BLUETOOTH_CONNECT
}, MyActivity.REQUEST_BLUETOOTH_PERMISSIONS);
}
}
}
}

Permissions - How do I request and/or change them in phones running MIUI during runtime?

Apparently the MIUI OS has already implemented its own Permissions system before Marshmallow does. I'm currently testing a video recording app for the Xiaomi Mi 4i, which uses a MIUI based on API 21 [Android 5.0.2], and it needs the Record Audio permission which is not granted by default by MIUI's Permissions Manager.
So far the way I've managed to alter the permissions is by accessing the Permissions Manager window for the app on clicking the OK button in the AlertDialog:
isMIUI = MIUIUtils.isMIUI();
if(isMIUI)
{
AlertDialog.Builder adb = new AlertDialog.Builder(this);
adb.setMessage("If you intend to use the video recording feature, please enable the 'Record Audio' permission in the settings menu. You will be redirected there if you press OK.")
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
Intent intent = new Intent("android.settings.APPLICATION_DETAILS_SETTINGS");
intent.setClassName("com.miui.securitycenter", "com.miui.permcenter.permissions.AppPermissionsEditorActivity");
intent.putExtra("extra_pkgname", "com.picmix.mobile");
startActivity(intent);
}
})
.setNegativeButton("CANCEL", null)
.create();
adb.show();
}
But this isn't good enough for me. I need to check if the Record Audio permission is already checked in the MIUI Permissions Manager in order to run this only once.
How do I check for the permissions granted or to be notified in the MIUI Permissions Manager programmatically?
private boolean resourceCanBeAccessed() {
boolean response = true;
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if(ContextCompat.checkSelfPermission(this, Manifest.permission.RECORD_AUDIO)
== PackageManager.PERMISSION_DENIED ) {
ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.RECORD_AUDIO}, 1);
response = false;
}
}
return response;
}
You just need to call this method before accessing the resource. This method will return true if the permission is granted. It the permission is not granted then it will grant the permission

Broadcast Receivers not working in Android 6.0 Marshmallow

I just updated my Nexus 5 to android 6, until now my app was working fine, but now the broadcast receivers are not working. Has something changed in the new version?
Here is the code I tried that was working on previous versions but not in marshmallow -
Android Manifest
<intent-filter >
<action android:name="android.provider.Telephony.SMS_RECEIVED"/>
</intent-filter>
<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
<uses-permission android:name="android.permission.READ_SMS" ></uses-permission>
Broadcast Receiver
public String TAG ="someClass";
private static String ACTION_SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (action.equalsIgnoreCase(ACTION_SMS_RECEIVED)) {
Log.d(TAG, "Received...");
}
}
Service
Broadcast_receiver broadcast_receiver = new Broadcast_receiver();
IntentFilter filter1 = new IntentFilter();
filter1.addAction("android.provider.Telephony.SMS_RECEIVED");
registerReceiver(broadcast_receiver, filter1);
Similarly the broadcast receiver for PHONE_STATE is also not working.
Your app's target API level is 23, that is android M (6.0). In android M there are huge changes related to user-permissions.
Here is nice article explaining the changes.
As stated in Android - Requesting Permissions
Beginning in Android 6.0 (API level 23), users grant permissions to apps while the app is running, not when they install the app... The user can revoke the permissions at any time...
It's also stated that:
System permissions are divided into two categories, normal and dangerous:
Normal permissions do not directly risk the user's privacy. If your app lists a normal permission in its manifest, the system grants the permission automatically
Dangerous permissions can give the app access to the user's
confidential data. If you list
a dangerous permission, the user has to explicitly give approval to
your app
Here are full lists of Dangerous Permissions and Normal Permissions
All that basically means that you need to manually request for any dangerous permission, when it's actually needed.
Since it potentially might be needed multiple times in your code, you can create a reusable method that checks whether specific permission is granted already and if it's not - to request it from user.
Here an example:
Java
public class PermissionManager {
//A method that can be called from any Activity, to check for specific permission
public static void check(Activity activity, String permission, int requestCode){
//If requested permission isn't Granted yet
if (ActivityCompat.checkSelfPermission(activity, permission) != PackageManager.PERMISSION_GRANTED) {
//Request permission from user
ActivityCompat.requestPermissions(activity,new String[]{permission},requestCode);
}
}
}
Kotlin
object PermissionManager {
//A method that can be called from any Activity, to check for specific permission
fun check(activity: Activity, permission: String, requestCode: Int) {
//If requested permission isn't Granted yet
if (ActivityCompat.checkSelfPermission(activity, permission) != PackageManager.PERMISSION_GRANTED) {
//Request permission from user
ActivityCompat.requestPermissions(activity, arrayOf(permission), requestCode)
}
}
}
Usage:
Java
//Inside your activity:
//1. Define static constant for each permission request
public static final int REQUEST_CODE_FOR_SMS=1;
//2. When needed (for example inside .onStart event) use method PermissionManager.check for requested permission
#Override
protected void onStart() {
super.onStart();
PermissionManager.check(this, Manifest.permission.RECEIVE_SMS, REQUEST_CODE_FOR_SMS);
}
//3. Handle User's response for your permission request
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
if(requestCode==REQUEST_CODE_FOR_SMS){//response for SMS permission request
if(grantResults[0]==PackageManager.PERMISSION_GRANTED){
//What to do if User allowed SMS permission
}else{
//What to do if user disallowed requested SMS permission
}
}
}
Kotlin
//Inside your activity:
//1. Define static constant for each permission request
val REQUEST_CODE_FOR_SMS = 1
//2. When needed (for example inside .onStart event) use method PermissionManager.check for requested permission
override fun onStart() {
super.onStart()
PermissionManager.check(this, Manifest.permission.RECEIVE_SMS, REQUEST_CODE_FOR_SMS)
}
//3. Handle User's response for your permission request
override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<String>, grantResults: IntArray) {
if (requestCode == REQUEST_CODE_FOR_SMS) {//response for SMS permission request
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
//What to do if User allowed SMS permission
} else {
//What to do if user disallowed requested SMS permission
}
}
}
Note:
If you need to use PermissionManager.check inside Fragment instance, use: getActivity() as its first parameter.
You can use checkSelfPermission inside Service instance, to check if some permission is granted already, but not requestPermissions to request it. Because checkSelfPermission can be used for any Context, but requestPermissions only for Activity
Marshmallow is blocking the dangerous permissions.
This doesn't apply to the scenario listed, but it might help someone else. I kept coming to this SO for why some of our Broadcast Receiver's weren't working. We have a custom permission setup and had the android:protectionLevel="dangerous". Changed it to android:protectionLevel= "signature"and everything started working.

Bluetooth LE Scan fails in the background - permissions

The following code works great on my Nexus 9 running Android 5.1.1 (Build LMY48M), but won't work on a Nexus 9 running Android 6.0 (Build MPA44l)
List<ScanFilter> filters = new ArrayList<ScanFilter>();
ScanSettings settings = (new ScanSettings.Builder().setScanMode(ScanSettings.SCAN_MODE_LOW_POWER)).build();
ScanFilter.Builder builder = new ScanFilter.Builder();
builder.setManufacturerData((int) 0x0118, new byte[]{(byte) 0xbe, (byte) 0xac}, new byte[]{(byte) 0xff, (byte)0xff});
ScanFilter scanFilter = builder.build();
filters.add(scanFilter);
mBluetoothLeScanner.startScan(filters, settings, new ScanCallback() {
...
});
On Android 5.x, the above code yields a callback when a manufacturer advertisement matching the scan filter is seen. (See example Logcat output below.) On the Nexus 9 with MPA44l, no callbacks are received. If you comment out the scan filter, callbacks are received successfully on the Nexus 9.
09-22 00:07:28.050 1748-1796/org.altbeacon.beaconreference D/BluetoothLeScanner﹕ onScanResult() - ScanResult{mDevice=00:07:80:03:89:8C, mScanRecord=ScanRecord [mAdvertiseFlags=6, mServiceUuids=null, mManufacturerSpecificData={280=[-66, -84, 47, 35, 68, 84, -49, 109, 74, 15, -83, -14, -12, -111, 27, -87, -1, -90, 0, 1, 0, 1, -66, 0]}, mServiceData={}, mTxPowerLevel=-2147483648, mDeviceName=null], mRssi=-64, mTimestampNanos=61272522487278}
Has anybody seen ScanFilters work on Android M?
The problem was not the scan filter, but background permissions.
Android 10-11:
In order to detect BLE devices in the background, you must have several permissions in the manifest. Place the following in your AndroidManifest.xml:
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.ACCESS_BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
Then add code like follows to your Activity to dynamically request these permissions from the user:
private static final int PERMISSION_REQUEST_FINE_LOCATION = 1;
private static final int PERMISSION_REQUEST_BACKGROUND_LOCATION = 2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
...
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (this.checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION)
== PackageManager.PERMISSION_GRANTED) {
if (this.checkSelfPermission(Manifest.permission.ACCESS_BACKGROUND_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
if (this.shouldShowRequestPermissionRationale(Manifest.permission.ACCESS_BACKGROUND_LOCATION)) {
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("This app needs background location access");
builder.setMessage("Please grant location access so this app can detect beacons in the background.");
builder.setPositiveButton(android.R.string.ok, null);
builder.setOnDismissListener(new DialogInterface.OnDismissListener() {
#TargetApi(23)
#Override
public void onDismiss(DialogInterface dialog) {
requestPermissions(new String[]{Manifest.permission.ACCESS_BACKGROUND_LOCATION},
PERMISSION_REQUEST_BACKGROUND_LOCATION);
}
});
builder.show();
}
else {
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Functionality limited");
builder.setMessage("Since background location access has not been granted, this app will not be able to discover beacons in the background. Please go to Settings -> Applications -> Permissions and grant background location access to this app.");
builder.setPositiveButton(android.R.string.ok, null);
builder.setOnDismissListener(new DialogInterface.OnDismissListener() {
#Override
public void onDismiss(DialogInterface dialog) {
}
});
builder.show();
}
}
} else {
if (!this.shouldShowRequestPermissionRationale(Manifest.permission.ACCESS_FINE_LOCATION)) {
requestPermissions(new String[]{Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.ACCESS_BACKGROUND_LOCATION},
PERMISSION_REQUEST_FINE_LOCATION);
}
else {
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Functionality limited");
builder.setMessage("Since location access has not been granted, this app will not be able to discover beacons. Please go to Settings -> Applications -> Permissions and grant location access to this app.");
builder.setPositiveButton(android.R.string.ok, null);
builder.setOnDismissListener(new DialogInterface.OnDismissListener() {
#Override
public void onDismiss(DialogInterface dialog) {
}
});
builder.show();
}
}
}
}
When you prompt the user for location permission, the OS dialog will give them the option to downgrade that permission request to "Allow Only While Using the App" vs. "Allow All the Time". If the user chooses the first option, you will not get detections in the background, even if everything else above is set up.
On Android 11, things get more complex still, as the OS offers yet another option of "Only this time" for the permission request. If your app targets SDK 30 (Android 11), it won't even offer the user the option for "Allow All the Time", and the user will have to go to Settings as a separate step to turn on all the time access. See here for more details on the way this works on Android 11.
For a broader discussion of the evolution of permissions prompting, see my blog post here.
Before Android 10:
Starting with Android M, Bluetooth LE scanning in the background is blocked unless the app has one of the following two permissions:
android.permission.ACCESS_COARSE_LOCATION
android.permission.ACCESS_FINE_LOCATION
The app I was testing did not request either of these permissions, so it did not work in the background (the only time the scan filter was active) on Android M. Adding the first one solved the problem.
I realized this was the problem because I saw the following line in Logcat:
09-22 22:35:20.152 5158 5254 E BluetoothUtils: Permission denial: Need ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION permission to get scan results
See here for details: https://code.google.com/p/android-developer-preview/issues/detail?id=2964
I had a similar problem with an app connecting to bluetooth. Not LE ScanFilter, but it was a permissions issue just like the OP had.
Root cause is that starting with SDK 23, you need to prompt the user for permissions at runtime using Activity's requestPermissions() method.
Here's what worked for me:
Add one of the following two lines to AndroidManifest.xml, inside the root node:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
In your Activity, before attempting to connect to bluetooth, call Activity's requestPermissions() method, which opens a system dialog to prompt the user for the permission. The permissions dialog opens in a different thread, so be sure to wait for the result before trying to connect to bluetooth.
Override Activity's onRequestPermissionsResult() to handle the result. This method will really only need to do something if the user refused to grant the permission, to tell the user that the app can't do the bluetooth activity.
This blog post has some example code that uses AlertDialogs to tell the user what's going on. It is a good starting point but has some shortcomings:
It doesn't handle waiting for the requestPermissions() thread to finish
The AlertDialog wrapping the call to requestPermissions() seems extraneous to me. A bare call to requestPermissions() is sufficient.
Add location permission along with BLE
<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" />
Copy Paste this method to request and grant location permission
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch (requestCode) {
case REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS: {
Map<String, Integer> perms = new HashMap<String, Integer>();
// Initial
perms.put(Manifest.permission.ACCESS_FINE_LOCATION, PackageManager.PERMISSION_GRANTED);
// Fill with results
for (int i = 0; i < permissions.length; i++)
perms.put(permissions[i], grantResults[i]);
// Check for ACCESS_FINE_LOCATION
if (perms.get(Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED
) {
// All Permissions Granted
// Permission Denied
Toast.makeText(ScanningActivity.this, "All Permission GRANTED !! Thank You :)", Toast.LENGTH_SHORT)
.show();
} else {
// Permission Denied
Toast.makeText(ScanningActivity.this, "One or More Permissions are DENIED Exiting App :(", Toast.LENGTH_SHORT)
.show();
finish();
}
}
break;
default:
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
}
#TargetApi(Build.VERSION_CODES.M)
private void stuffMarshMallow() {
List<String> permissionsNeeded = new ArrayList<String>();
final List<String> permissionsList = new ArrayList<String>();
if (!addPermission(permissionsList, Manifest.permission.ACCESS_FINE_LOCATION))
permissionsNeeded.add("Show Location");
if (permissionsList.size() > 0) {
if (permissionsNeeded.size() > 0) {
// Need Rationale
String message = "App need access to " + permissionsNeeded.get(0);
for (int i = 1; i < permissionsNeeded.size(); i++)
message = message + ", " + permissionsNeeded.get(i);
showMessageOKCancel(message,
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),
REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);
}
});
return;
}
requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),
REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);
return;
}
Toast.makeText(ScanningActivity.this, "No new Permission Required- Launching App .You are Awesome!!", Toast.LENGTH_SHORT)
.show();
}
private void showMessageOKCancel(String message, DialogInterface.OnClickListener okListener) {
new AlertDialog.Builder(ScanningActivity.this)
.setMessage(message)
.setPositiveButton("OK", okListener)
.setNegativeButton("Cancel", null)
.create()
.show();
}
#TargetApi(Build.VERSION_CODES.M)
private boolean addPermission(List<String> permissionsList, String permission) {
if (checkSelfPermission(permission) != PackageManager.PERMISSION_GRANTED) {
permissionsList.add(permission);
// Check for Rationale Option
if (!shouldShowRequestPermissionRationale(permission))
return false;
}
return true;
}
And then in onCreate check for permission
if (Build.VERSION.SDK_INT >= 23) {
// Marshmallow+ Permission APIs
stuffMarshMallow();
}
Hope it save your time.
If your app targets Android Q, it's not enough with only coarse location, you need to use fine location, otherwise you will get this error:
E/BluetoothUtils: Permission denial: Need ACCESS_FINE_LOCATION permission to get scan results
