How to take storage permission in Android 11

My Topic,
i am trying to take storage permission in android, my permission code works in below andoid 11 ,
but problem is when i try to take storage permission in android 11 then code not works , so please help me..
This is my code:-
This is my AndroidManifest.xml Code
android:requestLegacyExternalStorage="true"
This is my JavaCode Code
#Override
protected void onActivityResult(int _requestCode, int _resultCode, Intent _data) {
super.onActivityResult(_requestCode, _resultCode, _data);
if (_resultCode == RESULT_OK){
if (Build.VERSION.SDK_INT == Build.VERSION_CODES.R){
if (Environment.isExternalStorageManager()){
Toast.makeText(this,"Permission Granted",Toast.LENGTH_SHORT).show();
i.setClass(getApplicationContext(), Main2Activity.class);
startActivity(i);
} else {
_takePermission();
}
}
}
switch (_requestCode) {
default:
break;
}
}
public boolean _isPermissionGranted() {
if (Build.VERSION.SDK_INT == Build.VERSION_CODES.R){
return Environment.isExternalStorageManager();
} else {
int readexternalStoragePermission = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE);
return readexternalStoragePermission == PackageManager.PERMISSION_GRANTED;
}
}
public void _takePermission() {
if (Build.VERSION.SDK_INT == Build.VERSION_CODES.R) {
try {
Intent intent = new Intent(Settings.ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION);
intent.addCategory("android.intent.category.DEFAULT");
intent.setData(Uri.parse(String.format("package:%s",getApplicationContext().getPackageName())));
startActivityForResult(intent,100);
} catch (Exception exception){
Intent intent = new Intent();
intent.setAction(Settings.ACTION_MANAGE_ALL_FILES_ACCESS_PERMISSION);
startActivityForResult(intent,100);
}
} else {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},101);
}
}
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (grantResults.length > 0){
if (requestCode == 101){
boolean readExternalStorage = grantResults[0] == PackageManager.PERMISSION_GRANTED;
if (readExternalStorage){
Toast.makeText(this,"Permission Granted",Toast.LENGTH_SHORT).show();
i.setClass(getApplicationContext(), Main2Activity.class);
startActivity(i);
} else {
_takePermission();
}
}
}
Above is the complete code, please check and tell me what my mistake is, and what is the correct bridge.
Thanks for watching..

android:requestLegacyExternalStorage="true" will not affect if your app targetSdk > 30 (Android 11 and above).
Must add this to manifest:
Request to permission:
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.MANAGE_EXTERNAL_STORAGE}, 1);
Check whether app can access storage:
if (!Environment.isExternalStorageManager())
Request to access "All files and media" access:
Intent intent = new Intent();
intent.setAction(Settings.ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION);
Uri uri = Uri.fromParts("package", this.getPackageName(), null);
intent.setData(uri);
startActivity(intent);

Requesting permissions in Android

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();
}
}
...........
}

Asking for camera permission

I am trying to get access to the camera from within the app. I have the following code and all is working except it's not giving the user the option to grant permissions. Not quite sure what has gone wrong with it.
public void takePicture (View view) {
if (checkSelfPermission(Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED)
{
//requestPermissions(new String[]{Manifest.permission.CAMERA}, MY_CAMERA_PERMISSION_CODE);
ActivityCompat.requestPermissions(this, new String[] {Manifest.permission.CAMERA}, MY_CAMERA_PERMISSION_CODE);
}
else
{
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
}
public void saveButton (View view) {
Log.i("info", "stuff");
}
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults)
{
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == MY_CAMERA_PERMISSION_CODE)
{
if (grantResults[0] == PackageManager.PERMISSION_GRANTED)
{
Toast.makeText(this, "camera permission granted", Toast.LENGTH_LONG).show();
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
else
{
Toast.makeText(this, "camera permission denied", Toast.LENGTH_LONG).show();
}
}
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
}
}
Once the button is clicked the toast comes up to show that permissions have not been granted but no option to grant them in the first place?

Please make sure you have added camera permission in Androidmanifeast.xml
and minor change in your code replace below line
if (checkSelfPermission(Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED)
with
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED)

Android Multiple Permissions Error

I have a method that should check if some permission that I need to have are Granted or not :
public boolean checkCamera(){
String[] permissions= new String[]{
Manifest.permission.WRITE_EXTERNAL_STORAGE,
Manifest.permission.CAMERA};
int result;
List<String> listPermissionsNeeded = new ArrayList<>();
for (String p:permissions) {
result = ContextCompat.checkSelfPermission(getApplicationContext(),p);
if (result != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(p);
}
}
if (!listPermissionsNeeded.isEmpty()) {
ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]),MULTIPLE_PERMISSIONS );
return false;
}
return true;
}
If not, it request these permissions. The problem is, if I denied one of them it pass as valid Permission.
private void requestPermissionCamera(){
if(checkCamera()){
values.put(MediaStore.Images.Media.TITLE, "New Picture");
values.put(MediaStore.Images.Media.DESCRIPTION, "From your Camera");
imageUri = getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intent,requestCodeCamera);
}
}
In the moment that checks, it's not returning false as it should and on RequestResult the same thing.
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
switch (requestCode){
case MULTIPLE_PERMISSIONS:
if(grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){
values.put(MediaStore.Images.Media.TITLE, "New Picture");
values.put(MediaStore.Images.Media.DESCRIPTION, "From your Camera");
imageUri = getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intent,requestCodeCamera);
} else {
Toast.makeText(this, "Not All permissions are granted", Toast.LENGTH_SHORT).show();
}
break;

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();
}
}
}
