My internal android application worked fine on Samsung Tab S2 and it automatically got permissions to access 'storage' and 'location' of the device. But, when I am installing the application on newer Samsung Galaxy Tab S7, I have to manually provide permission for the app in settings. By default it is set to "No permissions allowed" How cam I automate this.
AndroidManifest.xml has following settings
<uses-sdk
android:minSdkVersion="21"
android:targetSdkVersion="22"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.CALL_PHONE"/>
<uses-permission android:name="android.permission.READ_SMS"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
Android permissions went through a radical change after android M was released. before that, developers can simply jam all the permissions in the AndroidManifesto file, and before the user installs the app, he/she has to approve all the permissions to run the app.
However, things are different now. Android expects that these permissions will be granted at rather runtime, i.e. when a feature that needs that permission is executed, it first requests for that permission, and based on user's reply handle that. If permission is granted, then good. If not, then simply display a message maybe stating that this feature will not work in the absence of that permission. In which case, because the user has already declined the permission, he/she now has to go to the settings to enable the previously declined permission.
You have to grant permission from the user. You can use it inside Fragment:
Java:
if (ActivityCompat.checkSelfPermission(getContext(),
android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) != PackageManager.PERMISSION_GRANTED) {
requestPermissions(getActivity(),
new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION},
REQUEST_LOCATION);
} else {
Log.e("DB", "PERMISSION GRANTED");
}
Kotlin:
if (ActivityCompat.checkSelfPermission(getContext(),
Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) != PackageManager.PERMISSION_GRANTED) {
requestPermissions(getActivity(), arrayOf(Manifest.permission.ACCESS_FINE_LOCATION),
REQUEST_LOCATION)
} else {
Log.e("DB", "PERMISSION GRANTED")
}
and inside Activity:
Java:
int checkPermission= ContextCompat.checkSelfPermission(getContext(), Manifest.permission.CAMERA);
if (checkPermission!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions((Activity)getContext(), new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, REQUEST_LOCATION);
}
else {
Log.e("DB", "PERMISSION GRANTED")
}
Kotlin:
val checkPermission = ContextCompat.checkSelfPermission(getContext(), Manifest.permission.CAMERA)
if (checkPermission != PackageManager.PERMISSION_GRANTED)
{
ActivityCompat.requestPermissions(getContext() as Activity, arrayOf<String>(Manifest.permission.ACCESS_FINE_LOCATION), REQUEST_LOCATION)
}
else
{
Log.e("DB", "PERMISSION GRANTED")
}
I'm trying to start a ACTION_IMAGE_CAPTURE activity in order to take a picture in my app and I'm getting the error in the subject.
Stacktrace:
FATAL EXCEPTION: main
Process: il.ac.shenkar.david.todolistex2, PID: 3293
java.lang.SecurityException: Permission Denial: starting Intent { act=android.media.action.IMAGE_CAPTURE cmp=com.google.android.GoogleCamera/com.android.camera.CaptureActivity } from ProcessRecord{22b0eb2 3293:il.ac.shenkar.david.todolistex2/u0a126} (pid=3293, uid=10126)
with revoked permission android.permission.CAMERA
The camera permissions is added to the manifest.xml fie:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_CALENDAR" />
<uses-permission android:name="android.permission.WRITE_CALENDAR" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA" />
Here is the call to open the camera:
RadioGroup radioGroup = (RadioGroup) findViewById(R.id.statusgroup);
radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId)
{
RadioButton rb = (RadioButton) findViewById(R.id.donestatusRBtn);
if(rb.isChecked())
{
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
}
});
Remove this permission
<uses-permission android:name="android.permission.CAMERA"/>
I faced this error executing my app in android 7. After tests I noticed user permission wasn't in project A but it was in project B, that I only tested in android 5 devices. So I remove that permission in project B in order to run it on other device that targets android 7 and it finally could open.
In adittion I added the fileprovider code that Android suggests here https://developer.android.com/training/camera/photobasics.html
Hope this helps.
hi you can use these permission in your manifest file with other permission,
<uses-feature
android:name="android.hardware.camera.any"
android:required="true" />
<uses-feature
android:name="android.hardware.camera.autofocus"
android:required="false" />
Now we have very sorted way for permission handling. So,here is the steps. I have added here for kotlin.
Step 1. Declare this as global variable or any where.
private val permissions = registerForActivityResult(ActivityResultContracts.RequestMultiplePermissions()) { granted ->
granted.entries.forEach {
when (it.value) {
true -> {
// Call whatever you want to do when someone allow the permission.
}
false -> {
showPermissionSettingsAlert(requireContext())
}
}
}
}
Step 2.
// You can put this line in constant.
val storagePermission = arrayOf(
Manifest.permission.READ_EXTERNAL_STORAGE
)
// You can put this in AppUtil.
fun checkPermissionStorage(context: Context): Boolean {
val result =
ContextCompat.checkSelfPermission(context, Manifest.permission.READ_EXTERNAL_STORAGE)
return result == PackageManager.PERMISSION_GRANTED
}
// Put this where you need Permission check.
if (!checkPermissionStorage(requireContext())) {
permissions.launch(
storagePermission
)
} else {
// Permission is already added.
}
Step 3. Permission rejection Dialog. If you want you can use this.
fun showPermissionSettingsAlert(context: Context) {
val builder = AlertDialog.Builder(context)
builder.setTitle("Grant Permission")
builder.setMessage("You have rejected the Storage permission for the application. As it is absolutely necessary for the app to perform you need to enable it in the settings of your device. Please select \"Go to settings\" to go to application settings in your device.")
builder.setPositiveButton("Allow") { dialog, which ->
val intent = Intent()
intent.action = Settings.ACTION_APPLICATION_DETAILS_SETTINGS
val uri = Uri.fromParts("package", context.packageName, null)
intent.data = uri
context.startActivity(intent)
}
builder.setNeutralButton("Deny") { dialog, which ->
dialog.dismiss()
}
val dialog = builder.create()
dialog.show()
}
Thankyou
hope this will help you (Y).
Here is how I solved mine:
First of all I think the issue arises when you try to use your device Camera on (SDK < 26) without FULL permissions.
Yes, even though you have already included this permission:
<uses-permission android:name="android.permission.CAMERA"/>
To solve this issue I changed that to this:
<uses-permission android:name="android.permission.CAMERA"
android:required="true"
android:requiredFeature="true"/>
This information from the Android Docs, might be really helpful
If your application uses, but does not require a camera in order to function, instead set android:required to false. In doing so, Google Play will allow devices without a camera to download your application. It's then your responsibility to check for the availability of the camera at runtime by calling hasSystemFeature(PackageManager.FEATURE_CAMERA_ANY). If a camera is not available, you should then disable your camera features.
In my case the problem was related to my emulator permissions ,
To fix the issue :
1- Go to Settings of your emulator.
2- Look for Apps and Notifications.
3- Click on Add Permission.
see the pic : https://i.stack.imgur.com/z4GfK.png
4- Select Camera of the list.
5- Look for your Application in the provided list.
6- Enable Camera.
see the pic : https://i.stack.imgur.com/dJ8wG.pngEnjoy
Now you can use your camera on your emulator :)
private String [] permissions = {"android.permission.WRITE_EXTERNAL_STORAGE", "android.permission.ACCESS_FINE_LOCATION", "android.permission.READ_PHONE_STATE", "android.permission.SYSTEM_ALERT_WINDOW","android.permission.CAMERA"};
on your OnCreate add this:
int requestCode = 200;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions(permissions, requestCode);
}
As some have pointed out, one solution is removing the Camera Permission from AndroidManifest.xml, i.e., remove this line:
<uses-permission android:name="android.permission.CAMERA" />
However, that was not enough for me, as I needed the Camera Permission for something else in my app. So what worked for me was tagging that permission as not required, like this:
<uses-permission android:name="android.permission.CAMERA" android:required="false" />
short answer ...its looking for permissions , upon failing permissions it throws exception ; moreover in this case its looking for Two Permissions i.e. first Storage and second Camera.
long answer.....Give it the permissions write way to work on all Versions of Android.I am looping to get both permissions Storage and Camera, So that it will work with Intent.
maintain in AndroidManifest.xml
<uses-feature
android:name="android.hardware.camera.any"
android:required="true" />
<uses-feature
android:name="android.hardware.camera.autofocus"
android:required="false" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
check or request permissions by
private void myStoragePermission() {
if (ContextCompat.checkSelfPermission(Activity_Scan_QR.this, Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
myCameraPermission();
} else {
//changed here
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, REQUEST_WRITE_PERMISSION);
}
}
}
//+10 changed its sinature as Fragment; without it onRequestPermissionsResult won't bbe called
private void myCameraPermission() {
if (ContextCompat.checkSelfPermission(Activity_Scan_QR.this, Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED) {
takePicture();
} else {
//changed here
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions(new String[]{Manifest.permission.CAMERA}, REQUEST_CAMERA_PERMISSION);
}
}
}
add onRequestPermissionsResult
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode) {
case REQUEST_WRITE_PERMISSION:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
myStoragePermission();
} else {
showSnackbar(R.string.act_ScanQR_txt13, R.string.settings,
new View.OnClickListener() {
#Override
public void onClick(View view) {
// Build intent that displays the App settings screen.
Intent intent = new Intent();
intent.setAction(
Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
Uri uri = Uri.fromParts("package",
BuildConfig.APPLICATION_ID, null);
intent.setData(uri);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
});
}
case REQUEST_CAMERA_PERMISSION:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
takePicture();
} else {
showSnackbar(R.string.act_ScanQR_txt14, R.string.settings,
new View.OnClickListener() {
#Override
public void onClick(View view) {
// Build intent that displays the App settings screen.
Intent intent = new Intent();
intent.setAction(
Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
Uri uri = Uri.fromParts("package",
BuildConfig.APPLICATION_ID, null);
intent.setData(uri);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
});
}
}
}
in above code takePicture(); is where I call for intent (start intent) , upon getting both the Storage and Camera permissions.
Don't get confused by reading a lot on error ;)
For future references, if someone encounters the problem in flutter related android projects:
https://github.com/apptreesoftware/flutter_barcode_reader/issues/32#issuecomment-420516729
In case anyone else get's this issue, my problem was that the app wasn't requesting any permissions when I ran it. It seems xiaomi devices automatically deny permissions to apps installed through adb. I just enabled the permissions through settings and it worked.
In case you need to keep
<uses-permission android:name="android.permission.CAMERA" />
permission in manifest, just make sure it is granted before opening system camera.
In modern android, you can do that like this:
val cameraPermissionResult =
registerForActivityResult(ActivityResultContracts.RequestPermission()) { permitted ->
if (permitted) {
openSystemCamera()
}
}
You can use cameraPermissionResult as follows:
cameraPermissionResult.launch(Manifest.permission.CAMERA)
If your app has already that permission granted it will just call openSystemCamera() without any user action required.
In other case permission dialog will be shown and system camera will be opened based on permission user chooses.
I'm quite late but please check this because there's always some update
As per official developer page - https://developer.android.com/training/camera/photobasics, you don't need to use uses-permission in Manifest.xml instead use uses-feature :
<uses-feature
android:name="android.hardware.camera"
android:required="false" />
Notice - it's uses-feature, not uses-permission ,
Check properly, if you are using uses-permission and uses-feature both at the same, possibly you will the same crash (this note is most important then updated content from official page, because i used both of the params at the same time and faced this crash, also when i started working on camera module in my app, i don't know why i wasn't faced this issue but now app just started crashing suddenly)
more info about android:required from developer page :
If your application uses, but does not require a camera in order to function, instead set android:required to false. In doing so, Google Play will allow devices without a camera to download your application. It's then your responsibility to check for the availability of the camera at runtime by calling hasSystemFeature(PackageManager.FEATURE_CAMERA_ANY). If a camera is not available, you should then disable your camera features.
in your androidManifest, you have to add :
<uses-feature android:name="android.hardware.camera" />
here is an full Manifest example of android camera project
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" />

In case anyone else get's this issue, my problem was that the app wasn't requesting any permissions when I ran it. It seems xiaomi devices automatically deny permissions to apps installed through adb. I just enabled the permissions through settings and it worked.
In case you need to keep
<uses-permission android:name="android.permission.CAMERA" />
permission in manifest, just make sure it is granted before opening system camera.
In modern android, you can do that like this:
val cameraPermissionResult =
registerForActivityResult(ActivityResultContracts.RequestPermission()) { permitted ->
if (permitted) {
openSystemCamera()
}
}
You can use cameraPermissionResult as follows:
cameraPermissionResult.launch(Manifest.permission.CAMERA)
If your app has already that permission granted it will just call openSystemCamera() without any user action required.
In other case permission dialog will be shown and system camera will be opened based on permission user chooses.
I'm quite late but please check this because there's always some update
As per official developer page - https://developer.android.com/training/camera/photobasics, you don't need to use uses-permission in Manifest.xml instead use uses-feature :
<uses-feature
android:name="android.hardware.camera"
android:required="false" />
Notice - it's uses-feature, not uses-permission ,
Check properly, if you are using uses-permission and uses-feature both at the same, possibly you will the same crash (this note is most important then updated content from official page, because i used both of the params at the same time and faced this crash, also when i started working on camera module in my app, i don't know why i wasn't faced this issue but now app just started crashing suddenly)
more info about android:required from developer page :
If your application uses, but does not require a camera in order to function, instead set android:required to false. In doing so, Google Play will allow devices without a camera to download your application. It's then your responsibility to check for the availability of the camera at runtime by calling hasSystemFeature(PackageManager.FEATURE_CAMERA_ANY). If a camera is not available, you should then disable your camera features.
in your androidManifest, you have to add :
<uses-feature android:name="android.hardware.camera" />
here is an full Manifest example of android camera project
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
