Do manifest permissions like "SEND_SMS" override the app permissions in Settings like "SMS" if it is set to off? The don't seem to set the later to on.
<uses-permission android:name="android.permission.SEND_SMS" />
<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.READ_SMS" />
SMS for the app settings set to "on" is expected. No error messages are being displayed.
Check all the permissions at runtime...in your MainActivity, so that if permissions are being off from settings then it will again ask for permissions when you open the application.
Call this method in onCreate() of your MainActivity.
private boolean checkAndRequestPermissions() {
int SEND_SMS = ContextCompat.checkSelfPermission(this, Manifest.permission.SEND_SMS);
int RECEIVE_SMS = ContextCompat.checkSelfPermission(this, Manifest.permission.RECEIVE_SMS);
int READ_SMS = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_SMS);
List<String> listPermissionsNeeded = new ArrayList<>();
if (SEND_SMS != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.SEND_SMS);
}
if (RECEIVE_SMS != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.RECEIVE_SMS);
}
if (READ_SMS != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.READ_SMS);
}
if (!listPermissionsNeeded.isEmpty()) {
ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray
(new String[listPermissionsNeeded.size()]), 101);
return false;
}
return true;
}

Android Studio 3.4.
A device on android 6.0
in manifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

In my simple class (no activity/fragment) I have:
public class LocationHelper {
if (locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) {
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locListener);
}
I have compile error:
Missing permissions required by LocationManager.requestLocationUpdates: android.permission.ACCESS_COARSE_LOCATION or android.permission.ACCESS_FINE_LOCATION
}
Call this checkAndRequestPermissions() Method whenevr you want permission
public boolean checkAndRequestPermissions() {
int internet = ContextCompat.checkSelfPermission(mContext,
Manifest.permission.INTERNET);
int loc = ContextCompat.checkSelfPermission(mContext,
Manifest.permission.ACCESS_COARSE_LOCATION);
int loc2 = ContextCompat.checkSelfPermission(mContext,
Manifest.permission.ACCESS_FINE_LOCATION);
List<String> listPermissionsNeeded = new ArrayList<>();
if (internet != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.INTERNET);
}
if (loc != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.ACCESS_COARSE_LOCATION);
}
if (loc2 != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.ACCESS_FINE_LOCATION);
}
if (!listPermissionsNeeded.isEmpty()) {
ActivityCompat.requestPermissions((Activity) mContext, listPermissionsNeeded.toArray
(new String[listPermissionsNeeded.size()]), 1);
return false;
}
return true;
}
You need to have both of those permissions to your manifest file:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
So check your manifest file and make sure that you have both of them.
Add ACCESS_FINE_LOCATION and ACCESS_COARSE_LOCATION in AndroidManifest File
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
Ask for permission at runtime to use device current location as below :
if (ActivityCompat.checkSelfPermission(YourActivity.this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(YourActivity.this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(YourActivity.this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);
return;
}else{
// Write you code here if permission already given.
// Call LocationHelper
}
Handle when user allow to use device current location or not :
#Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
if (grantResults.length > 0 && grantResults[0] ==
PackageManager.PERMISSION_GRANTED) {
// Write you code here if permission already given.
// Call LocationHelper
} }else{
// you must ask location permission again
}
}
I have set in my android manifest the following permissions:
<uses-sdk android:minSdkVersion="16" android:targetSdkVersion="27" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.GET_ACCOUNTS_PRIVILEGED"/>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<application android:label="MyApp" android:icon="#drawable/icon">
But if a take a look at the app settings on my phone, the app has no permissions set. Should the app not asking me if I want give this grant on installation?
Thanks
Android permissions work like this :
If your permission is normal permission it will be auto-granted.
If we are talking about dangerous permissions it goes like this :
If the device API level is <= 22 / targetSdkVersion is 22 or lower:
In that case, the user will be asked (by the system) in the install time to grant all the dangerous permissions for the app.
If the device API level is > 22 and targetSdkVersion is above 22:
The user will not accept dangerous permissions at install time.
You must ask the user to grant access to the dangerous permissions at runtime - when you do ask your user to give access to those permissions on run time he will see system dialog
that asks him to accept or decline the permissions.
So if your app did not ask permission at install time it may have higher API level.
For more information, you can check this
Do it like this.
Write a function to add the needed permission to a list
private boolean addPermission(List<String> permissionsList, String permission) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (checkSelfPermission(permission) != PackageManager.PERMISSION_GRANTED) {
permissionsList.add(permission);
// Check for Rationale Option
return shouldShowRequestPermissionRationale(permission);
}
}
return true;
}
Add a function to create the list
private void requestPermissions() {
List<String> permissionsNeeded = new ArrayList<String>();
final List<String> permissionsList = new ArrayList<String>();
if (!addPermission(permissionsList, ACCESS_FINE_LOCATION))
permissionsNeeded.add("Location");
if (!addPermission(permissionsList, Manifest.permission.READ_EXTERNAL_STORAGE))
permissionsNeeded.add("Read");
if (!addPermission(permissionsList, Manifest.permission.WRITE_EXTERNAL_STORAGE))
permissionsNeeded.add("Write");
// add all your permissions needed except normal permissions
if (permissionsList.size() > 0) {
if (permissionsNeeded.size() > 0) {
// Need Rationale
StringBuilder message = new StringBuilder("You need to grant access to: \n- " + permissionsNeeded.get(0));
for (int i = 1; i < permissionsNeeded.size(); i++)
message.append("\n- ").append(permissionsNeeded.get(i));
showMessageOKCancel(message.toString(),
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),
REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);
}
}
}, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
finish();
}
});
return;
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),
REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);
}
}
}
Then, override the activity function onRequestPermissionsResult
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
switch (requestCode) {
case REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS:
Map<String, Integer> perms = new HashMap<String, Integer>();
// Initial
perms.put(ACCESS_FINE_LOCATION, PackageManager.PERMISSION_GRANTED);
// Fill with results
for (int i = 0; i < permissions.length; i++)
perms.put(permissions[i], grantResults[i]);
// Test ACCESS_FINE_LOCATION (if needed) or other permission
if (perms.get(ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// Permission Denied
Toast.makeText(MainActivity.this, "Some Permission is Denied", Toast.LENGTH_SHORT)
.show();
}
break;
default:
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
}
On your MainActivity in onCreatecall requestPermissions();
I need to request to Read permission but system permission dialogue does not appear. When I added the SMS Receive permission then dialogue appears but why it does not work on only SMS Read permission?
if (ContextCompat.checkSelfPermission(getApplicationContext(), Manifest.permission.READ_SMS)!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions((Activity) context, new String[]{ Manifest.permission.READ_SMS}, 101);
}
Try with this
if (ActivityCompat.checkSelfPermission(getContext(),
android.Manifest.permission.READ_SMS) != PackageManager.PERMISSION_GRANTED) {
requestPermissions(getActivity(),
new String[]{android.Manifest.permission.READ_SMS},
101);
} else {
Log.e("DB", "PERMISSION GRANTED");
}
Also make sure you have to add permission in Manifest.
<uses-permission android:name="android.permission.READ_SMS" />
I am developing an Android application that has its own video recorder feature. For that I need to request RECORD_AUDIO permission from the user. But when I request the permission, it is not showing the prompt to get the permission from the user.
This is my function that checks if the app needs to request permission and it does automatically if required.
private boolean isRecordAudioPermissionGranted()
{
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (ContextCompat.checkSelfPermission(this, Manifest.permission.RECORD_AUDIO) ==
PackageManager.PERMISSION_GRANTED) {
// put your code for Version>=Marshmallow
return true;
} else {
if (shouldShowRequestPermissionRationale(Manifest.permission.RECORD_AUDIO)) {
Toast.makeText(this,
"App required access to audio", Toast.LENGTH_SHORT).show();
}
requestPermissions(new String[]{Manifest.permission.RECORD_AUDIO
},AUDIO_RECORD_REQUEST_CODE);
return false;
}
} else {
// put your code for Version < Marshmallow
return true;
}
}
In the onCreate of the Activity, I call the function like this.
if(!isRecordAudioPermissionGranted())
{
Toast.makeText(getApplicationContext(), "Need to request permission", Toast.LENGTH_SHORT).show();
}
else{
Toast.makeText(getApplicationContext(), "No need to request permission", Toast.LENGTH_SHORT).show();
}
The app is saying that it needs to request permission, but it is just not prompting the request permission dialog. What is wrong with my code?
This are the permissions I added and use in the manifest file.
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.READ_PROFILE" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.VIBRATE"/>
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.Manifest.permission.RECORD_AUDIO"/>
<uses-feature android:name="android.hardware.camera"/>
<uses-feature android:name="android.hardware.camera.autofocus"/>
<uses-feature android:name="android.hardware.camera.front"/>
<uses-feature android:name="android.hardware.camera.front.autofocus"/>
<uses-feature android:name="android.hardware.sensor.accelerometer" android:required="true"/>
<uses-feature android:name="android.hardware.sensor.gyroscope" android:required="true"/>
<uses-feature android:name="android.software.vr.mode" android:required="true"/>
<uses-feature android:name="android.hardware.vr.high_performance" android:required="true"/>
For RECORD_AUDIO permission, correct permission string is
android.permission.RECORD_AUDIO
In your manifest you are using
<uses-permission android:name="android.Manifest.permission.RECORD_AUDIO"/>
which in incorrect and it must be
<uses-permission android:name="android.permission.RECORD_AUDIO"/>
add this in manifest file
in java
//Requesting run-time permissions
//Create placeholder for user's consent to record_audio permission.
//This will be used in handling callback
private final int MY_PERMISSIONS_RECORD_AUDIO = 1;
private void requestAudioPermissions() {
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.RECORD_AUDIO)
!= PackageManager.PERMISSION_GRANTED) {
//When permission is not granted by user, show them message why this permission is needed.
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.RECORD_AUDIO)) {
Toast.makeText(this, "Please grant permissions to record audio", Toast.LENGTH_LONG).show();
//Give user option to still opt-in the permissions
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.RECORD_AUDIO},
MY_PERMISSIONS_RECORD_AUDIO);
} else {
// Show user dialog to grant permission to record audio
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.RECORD_AUDIO},
MY_PERMISSIONS_RECORD_AUDIO);
}
}
//If permission is granted, then go ahead recording audio
else if (ContextCompat.checkSelfPermission(this,
Manifest.permission.RECORD_AUDIO)
== PackageManager.PERMISSION_GRANTED) {
//Go ahead with recording audio now
recordAudio();
}
}
//Handling callback
#Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
switch (requestCode) {
case MY_PERMISSIONS_RECORD_AUDIO: {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// permission was granted, yay!
recordAudio();
} else {
// permission denied, boo! Disable the
// functionality that depends on this permission.
Toast.makeText(this, "Permissions Denied to record audio", Toast.LENGTH_LONG).show();
}
return;
}
}
}
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" />
