Requesting permissions in Android - java

I am trying to request 2 permissions when the app opens up. It works fine, but when the user selects never ask again, a toast message should be displayed once. The toast message keeps on coming up repeatedly and does not stop. I cannot figure out the reason for this.
public void checkPermission(final Context context) {
if(ContextCompat.checkSelfPermission(context, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED || ContextCompat.checkSelfPermission(context, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale((Activity) context, Manifest.permission.READ_EXTERNAL_STORAGE) || ActivityCompat.shouldShowRequestPermissionRationale((Activity) context, Manifest.permission.CAMERA)) {
ActivityCompat.requestPermissions((Activity) context, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.CAMERA}, 1);
}
else {
ActivityCompat.requestPermissions((Activity) context, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.CAMERA}, 1);
}
}
}
#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 && grantResults[1] == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(this, "Both permissions granted", Toast.LENGTH_SHORT).show();
} else {
checkPermission(this);
}
if (requestCode == 1) {
for (int i = 0, len = permissions.length; i < len; i++) {
String permission = permissions[i];
boolean showRationale;
if (grantResults[i] == PackageManager.PERMISSION_DENIED) {
showRationale = shouldShowRequestPermissionRationale(permission);
if (!showRationale) {
Toast.makeText(this, "Denied", Toast.LENGTH_SHORT).show();
}
}
}
}
}
Above is the code that checks for permissions.
I would like to know why the toast message never stops popping up.

Try following code -
public class MainActivity extends AppCompatActivity{
private static final int STORAGE_PERMISSION_REQ_CODE = 1001;
private static final int CAMERA_PERMISSION_REQ_CODE = 1002;
private static final int BOTH_PERMISSION_REQ_CODE = 1003;
...........
private void checkPermission(){
if(hasBothPermission()){
// Has both permission
}
else if(hasReadStoragePermission(READ_EXTERNAL_STORAGE))
// Has Storage Permission request Camera Permission
requestPermissions(new String[]{CAMERA}, CAMERA_PERMISSION_REQ_CODE);
else if(hasCameraPermission(CAMERA))
// Has Camera Permission request Storage Permission
requestPermissions(new String[]{READ_EXTERNAL_STORAGE}, STORAGE_PERMISSION_REQ_CODE);
else
// Request Both Permission
requestPermissions(new String[]{READ_EXTERNAL_STORAGE, CAMERA},BOTH_PERMISSION_REQ_CODE);
}
private boolean hasBothPermission(){
return (ContextCompat.checkSelfPermission(this, CAMERA) == PackageManager.PERMISSION_GRANTED) &&
ContextCompat.checkSelfPermission(this, READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED;
}
private boolean hasCameraPermission(String perm) {
return (ContextCompat.checkSelfPermission(this, perm) == PackageManager.PERMISSION_GRANTED);
}
private boolean hasReadStoragePermission(String perm) {
return (ContextCompat.checkSelfPermission(this, perm) == PackageManager.PERMISSION_GRANTED);
}
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
if(requestCode == STORAGE_PERMISSION_REQ_CODE){
if(hasReadStoragePermission(READ_EXTERNAL_STORAGE))
Toast.makeText(this, "Storage Permission Granted", Toast.LENGTH_SHORT).show();
else
Toast.makeText(this, "Storage Permission Failed, Request Again", Toast.LENGTH_SHORT).show();
}
else if(requestCode == CAMERA_PERMISSION_REQ_CODE){
if(hasCameraPermission(CAMERA))
Toast.makeText(this, "Camera Permission Granted", Toast.LENGTH_SHORT).show();
else
Toast.makeText(this, "Camera Permission Failed, Request Again", Toast.LENGTH_SHORT).show();
}
else {
if(hasBothPermission())
Toast.makeText(this, "Permission Granted Success", Toast.LENGTH_SHORT).show();
else
Toast.makeText(this, "Permission Failed Request Permission Again", Toast.LENGTH_SHORT).show();
}
}
...........
}

how do i make it so that when the user accepts location permission it will start working and no need to restart the app

how do i make it so that when the user accepts location permission it will start working and no need to restart the app. At first on launch, my app will request location permission from the user, but even after they accept it will not run properly using these permissions. It will only work properly after restarting the app.

error ArrayIndexOutOfBoundsException occurs only sometimes, user permission?

Some users in my app get this error:
Caused by: java.lang.ArrayIndexOutOfBoundsException: at
com.file.gt.MainActivity.onRequestPermissionsResult
(MainActivity.java:234) at android.app.Activity.requestPermissions
(Activity.java:5323) at com.file.gt.MainActivity.onCreate

android.app.Instrumentation.callActivityOnCreate
(Instrumentation.java:1309) at
android.app.ActivityThread.performLaunchActivity
(ActivityThread.java:3480)
It occurs only sometimes, with some users.
I have this in my app:
private final String [] permissions = {
"android.permission.RECORD_AUDIO",
"android.permission.READ_PHONE_STATE"
};
int requestCode = 200;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (checkSelfPermission(permissions[0]) == PackageManager.PERMISSION_DENIED ||
checkSelfPermission(permissions[1]) == PackageManager.PERMISSION_DENIED) {
requestPermissions(permissions, requestCode);
}
}
and this:
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if(grantResults[0] == PackageManager.PERMISSION_GRANTED
&& grantResults[1] == PackageManager.PERMISSION_GRANTED) {
recreate(); // 234
}
else {
AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();
alertDialog.setTitle(getString(R.string.alert_title));
alertDialog.setMessage(getString(R.string.alert_text));
alertDialog.setButton(AlertDialog.BUTTON_NEUTRAL, "OK",
(dialog, which) -> dialog.dismiss());
alertDialog.show();
}
}
Any ideas what is wrong and what I'm doing wrong?
Thanks.
When you get an ArrayIndexOutOfBoundsException it means you are accessing an array index outside the array size. Your stack trace says it happens in onRequestPermissionsResult, and the only array you access there is grantResults.
What can sometimes happen is that grantResults is empty in onRequestPermissionsResult if the user declines the permissions, so you should check its size before accessing its members
if(grantResults.length == 2 &&
grantResults[0] == PackageManager.PERMISSION_GRANTED &&
grantResults[1] == PackageManager.PERMISSION_GRANTED) {
recreate();
}
else {
// handle permissions not granted
}
Alternately, if you use the new registerForActivityResult approach you can get around this entirely. Have a look here for more info, or here for an example use.
private final String [] permissions = {
android.Manifest.permission.RECORD_AUDIO,
android.Manifest.permission. READ_PHONE_STATE,
};
int requestCode = 200;
public static boolean hasPermissions(Context context, String... permissions) {
if (context != null && permissions != null) {
for (String permission : permissions) {
if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
return false;
}
}
}
return true;}
//user this code to check
if (!hasPermissions(this, PERMISSIONS)) {
ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL);
}else{
recreate();
}

Permission Not Granted

I'm trying to get access to the system settings, but it seems my method that requests the permission always returns false. My knowledge is limited so I don't really know where to start to fix it
private void getPermissions(){
boolean value;
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M){
value = Settings.System.canWrite(getApplicationContext());
if(value) {
success = true;
}else{
Intent intent = new
Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS);
intent.setData(Uri.parse("package:" +
getApplicationContext().getPackageName()));
startActivity(intent);
}
}
}
the getPermission() is called upon the creation of the app.
Try this
String[] permissionsRequired = new String{Manifest.permission.CAMERA,
Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.RECORD_AUDIO};
//on button click
Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
Uri uri = Uri.fromParts("package", getPackageName(), null);
intent.setData(uri);
startActivityForResult(intent, REQUEST_PERMISSION_SETTING);
#Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case PERMISSION_REQUEST_CODE:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(getApplicationContext(), "Permission Granted", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getApplicationContext(), "Permission Denied", Toast.LENGTH_SHORT).show();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if ((ContextCompat.checkSelfPermission(this, permissionsRequired[0])
!= PackageManager.PERMISSION_GRANTED) ||
(ContextCompat.checkSelfPermission(this, permissionsRequired[1])
!= PackageManager.PERMISSION_GRANTED) ||
(ContextCompat.checkSelfPermission(this, permissionsRequired[2])
!= PackageManager.PERMISSION_GRANTED)) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermission();
}
}
}
}
break;
}
}
public void requestPermission() {
ActivityCompat.requestPermissions((Activity) this, permissionsRequired, REQUEST_PERMISSION_SETTING);
}

Not sending message

hi i am using this code to send sms on any number but it is working for the first time and there is no next time. any fix? is there a problem in MY_PERMISSION_REQUEST_SEND_SMS? Is there any other short method to send sms?
protected void SendSms() {
phonenumber=number.getText().toString();
message= txt.getText().toString();
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.SEND_SMS)
!= PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.SEND_SMS)) {
} else {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.SEND_SMS},
MY_PERMISSIONS_REQUEST_SEND_SMS);
}
}
}
#Override
public void onRequestPermissionsResult(int requestCode,String permissions[],
int[] grantResults) {
switch (requestCode) {
case MY_PERMISSIONS_REQUEST_SEND_SMS: {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED)
{
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phonenumber, null, message, null,
null);
Toast.makeText(getApplicationContext(), "SMS sent.",
Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(),
"SMS faild, please try again.",
Toast.LENGTH_LONG).show();
return;
}
}
}
You don't have the condition when you already have the access to Send SmS permission
Put else for outer if and execute your send sms code
This is because you missed to call smsManager send sms if permission granted
Better make a method,
private void smsSend(){
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phonenumber, null, message, null,
null);
Toast.makeText(getApplicationContext(), "SMS sent.",
Toast.LENGTH_LONG).show();
}
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.SEND_SMS)
!= PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.SEND_SMS)) {
} else {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.SEND_SMS},
MY_PERMISSIONS_REQUEST_SEND_SMS);
}
}
else{
smsSend(); //call method if already granted
}
and call this method after permission granted also,
#Override
public void onRequestPermissionsResult(int requestCode,String permissions[],
int[] grantResults) {
switch (requestCode) {
case MY_PERMISSIONS_REQUEST_SEND_SMS: {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED)
{
smsSend(); //call method after permission grant
} else {
Toast.makeText(getApplicationContext(),
"SMS faild, please try again.",
Toast.LENGTH_LONG).show();
return;
}
}
}
}

How to ask multiple permissions at the same time in android 6.0+

i want to ask the user to accept the following permissions at the same time(one by one), the permissions are like:
checkLocationPermission, checkReadSMS, checkCallingPermission, checkReadState, checkContactWriteState.
So, how i can ask all these permissions in my first screen itself.
Please help me out in this regard.
Thanks in advance.
You have to first check that user phone build version is 23.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
askPermissions(true);
} else {
startActivity(new Intent(PermissionsActivity.this, SplashActivity.class));
finish();
}
If version is 23 then you need to ask permissions.
private void askPermissions(boolean isForOpen) {
isRationale = false;
List permissionsRequired = new ArrayList();
final List<String> permissionsList = new ArrayList<String>();
if (!checkPermission(permissionsList, Manifest.permission.WRITE_EXTERNAL_STORAGE))
permissionsRequired.add("Write External Storage");
if (!checkPermission(permissionsList, Manifest.permission.CALL_PHONE))
permissionsRequired.add("Call phone");
if (!checkPermission(permissionsList, Manifest.permission.READ_PHONE_STATE))
permissionsRequired.add("Read phone state");
if (!checkPermission(permissionsList, Manifest.permission.READ_CONTACTS))
permissionsRequired.add("Read Contacts");
if (!checkPermission(permissionsList, Manifest.permission.RECEIVE_SMS))
permissionsRequired.add("Receive SMS");
if (!checkPermission(permissionsList, Manifest.permission.GET_ACCOUNTS))
permissionsRequired.add("Get Accounts");
if (!checkPermission(permissionsList, Manifest.permission.ACCESS_COARSE_LOCATION))
permissionsRequired.add("Location");
if (!checkPermission(permissionsList, Manifest.permission.ACCESS_FINE_LOCATION))
permissionsRequired.add("Location");
if (permissionsList.size() > 0 && !isRationale) {
if (permissionsRequired.size() > 0) {
}
if (isForOpen) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
ActivityCompat.requestPermissions(this, permissionsList.toArray(new String[permissionsList.size()]),
11);
}
}
} else if (isRationale) {
if (isForOpen) {
new android.support.v7.app.AlertDialog.Builder(this, R.style.AppCompatAlertDialogStyle)
.setTitle("Permission Alert")
.setMessage("You need to grant permissions manually. Go to permission and grant all permissions.")
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
Uri uri = Uri.fromParts("package", getPackageName(), null);
intent.setData(uri);
startActivityForResult(intent, 123);
}
})
.show();
}
} else {
startActivity(new Intent(PermissionsActivity.this, SplashActivity.class));
finish();
}
}
private boolean checkPermission(List permissionsList, String permission) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (ContextCompat.checkSelfPermission(this, permission) != PackageManager.PERMISSION_GRANTED) {
permissionsList.add(permission);
// Check for Rationale Option
if (!isFirst) {
if (!ActivityCompat.shouldShowRequestPermissionRationale(this, permission)) {
isRationale = true;
return false;
}
}
}
}
return true;
}
on the onRequestPermissionsResult you need to check which permissions granted
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
switch (requestCode) {
case 11:
Map<String, Integer> perms = new HashMap<String, Integer>();
// Initial
perms.put(Manifest.permission.WRITE_EXTERNAL_STORAGE, PackageManager.PERMISSION_GRANTED);
perms.put(Manifest.permission.CALL_PHONE, PackageManager.PERMISSION_GRANTED);
perms.put(Manifest.permission.READ_PHONE_STATE, PackageManager.PERMISSION_GRANTED);
perms.put(Manifest.permission.READ_CONTACTS, PackageManager.PERMISSION_GRANTED);
perms.put(Manifest.permission.RECEIVE_SMS, 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.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED &&
perms.get(Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED &&
perms.get(Manifest.permission.READ_PHONE_STATE) == PackageManager.PERMISSION_GRANTED &&
perms.get(Manifest.permission.READ_CONTACTS) == PackageManager.PERMISSION_GRANTED &&
perms.get(Manifest.permission.RECEIVE_SMS) == PackageManager.PERMISSION_GRANTED) {
// All Permissions Granted
startActivity(new Intent(PermissionsActivity.this, SplashActivity.class));
finish();
} else {
// Permission Denied
Toast.makeText(this, "Some Permission is Denied.", Toast.LENGTH_SHORT)
.show();
isFirst = false;
askPermissions(true);
}
break;
default:
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
}
If user has set the permission to never ask again then the application setting screen will open. User will allow/Deny permission there. You need to check again on the activityResult.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
askPermissions(true);
}
if (!hasPermissions()){
// your app doesn't have permissions, ask for them.
requestNecessaryPermissions();
}
else {
// your app already have permissions allowed.
// do what you want.
}
private boolean hasPermissions() {
int res = 0;
// list all permissions which you want to check are granted or not.
String[] permissions = new String[] {Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE};
for (String perms : permissions){
res = checkCallingOrSelfPermission(perms);
if (!(res == PackageManager.PERMISSION_GRANTED)){
// it return false because your app dosen't have permissions.
return false;
}
}
// it return true, your app has permissions.
return true;
}
private void requestNecessaryPermissions() {
// make array of permissions which you want to ask from user.
String[] permissions = new String[] {Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE};
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
// have arry for permissions to requestPermissions method.
// and also send unique Request code.
requestPermissions(permissions, REQUEST_CODE_STORAGE_PERMS);
}
}
/* when user grant or deny permission then your app will check in
onRequestPermissionsReqult about user's response. */
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grandResults) {
// this boolean will tell us that user granted permission or not.
boolean allowed = true;
switch (requestCode) {
case REQUEST_CODE_STORAGE_PERMS:
for (int res : grandResults) {
// if user granted all required permissions then 'allowed' will return true.
allowed = allowed && (res == PackageManager.PERMISSION_GRANTED);
}
break;
default:
// if user denied then 'allowed' return false.
allowed = false;
break;
}
if (allowed) {
// if user granted permissions then do your work.
dispatchTakePictureIntent();
}
else {
// else give any custom waring message.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (shouldShowRequestPermissionRationale(Manifest.permission.CAMERA)) {
Toast.makeText(MainActivity.this, "Camera Permissions denied", Toast.LENGTH_SHORT).show();
}
else if (shouldShowRequestPermissionRationale(Manifest.permission.WRITE_EXTERNAL_STORAGE)){
Toast.makeText(MainActivity.this, "Storage Permissions denied", Toast.LENGTH_SHORT).show();
