android marshmallow issue read a file from external storage - android

i try to copy a sqlite database from file in my external storage this worked fine in android version ( 4 and 5 ) but doesn't work in android 6 (marshmallow) why ?? please help , As required, in its manifest, the following permissions are requested :
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
here is my code :
if (Build.VERSION.SDK_INT >= 23) {
if (ContextCompat.checkSelfPermission(Main2ActivityAdmin.this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED || ContextCompat.checkSelfPermission(Main2ActivityAdmin.this, android.Manifest.permission.READ_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(Main2ActivityAdmin.this,
new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE, android.Manifest.permission.READ_EXTERNAL_STORAGE},
1);
} else {
Toast.makeText(Main2ActivityAdmin.this, "permission erreur", Toast.LENGTH_LONG).show();
}
} else {
Toast.makeText(Main2ActivityAdmin.this, "ok", Toast.LENGTH_LONG).show();
}
private boolean copyDatabase(Context context) {
try {
//InputStream inputStream = context.getAssets().open(DatabaseHelper.DBNAME);
File sdcard = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
File file = new File(sdcard, "sample.sqlite");
InputStream inputStream = null;
inputStream = new BufferedInputStream(new FileInputStream(file.getAbsolutePath()));
String outFileName = DatabaseHelper.DBLOCATION + DatabaseHelper.DBNAME;
OutputStream outputStream = new FileOutputStream(outFileName);
byte[]buff = new byte[1024];
int length = 0;
while ((length = inputStream.read(buff)) > 0) {
outputStream.write(buff, 0, length);
}
outputStream.flush();
outputStream.close();
Log.w("MainActivity","DB copied");
return true;
}catch (Exception e) {
e.printStackTrace();
return false;
}

Try this to put the permission
Also change WRITE_EXTERNAL_STORAGE to READ_EXTERNAL_STORAGE for Read permission
public class MyActivity extends AppCompatActivity {
private static final int REQUEST_RUNTIME_PERMISSION = 123;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (CheckPermission(MyActivity .this, Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
// you have permission go ahead
} else {
// you do not have permission go request runtime permissions
RequestPermission(MyDevIDS.this, Manifest.permission.WRITE_EXTERNAL_STORAGE, REQUEST_RUNTIME_PERMISSION);
}
}
#Override
public void onRequestPermissionsResult(int permsRequestCode, String[] permissions, int[] grantResults) {
switch (permsRequestCode) {
case REQUEST_RUNTIME_PERMISSION: {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// you have permission go ahead
} else {
// you do not have permission show toast.
}
return;
}
}
}
public void RequestPermission(MyActivity thisActivity, String Permission, int Code) {
if (ContextCompat.checkSelfPermission(thisActivity,
Permission)
!= PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
Permission)) {
} else {
ActivityCompat.requestPermissions(thisActivity,
new String[]{Permission},
Code);
}
}
}
public boolean CheckPermission(MyActivity context, String Permission) {
if (ContextCompat.checkSelfPermission(context,
Permission) == PackageManager.PERMISSION_GRANTED) {
return true;
} else {
return false;
}
}
}

How to access hidden files in android 11 programmatically?

I want to show whatsapp statuses in my app.
Till now I have done following:
public final String getStatusPath(boolean z) {
if (Build.VERSION.SDK_INT < 30) {
if (z) {
return Environment.getExternalStorageDirectory().getAbsolutePath() + "/WhatsApp Business/Media/.Statuses";
}
return Environment.getExternalStorageDirectory().getAbsolutePath() + "/WhatsApp/Media/.Statuses";
} else if (z) {
return Environment.getExternalStorageDirectory().getAbsolutePath() + "/Android/media/com.whatsapp.w4b/WhatsApp Business/Media/.Statuses";
} else {
return Environment.getExternalStorageDirectory().getAbsolutePath()+ "/Android/media/com.whatsapp/WhatsApp/Media/.Statuses";
}
}
private ArrayList<WhatStatusData> getStatusList() {
ArrayList<WhatStatusData> arrayList = new ArrayList<>();
File[] listFiles = new File(FileConstants.INSTANCE.getStatusPath(isBusiness)).listFiles();
int i = 0;
if (listFiles != null) {
if (listFiles.length == 0) {
Arrays.sort(listFiles);
}
int length = listFiles.length;
while (i < length) {
File file = listFiles[i];
i++;
String absolutePath = file.getAbsolutePath();
Uri fromFile = Uri.fromFile(file);
String name = file.getName();
if (!name.equals(".nomedia")) {
arrayList.add(new WhatStatusData(absolutePath, fromFile, name));
}
}
}
return arrayList;
}
In manifest
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
But I am not getting data in android 11.In other versions code is working properly.
Got the solution
There are two possibility for getting hidden files access in android 11
give MANAGE_EXTERNAL_STORAGE permission as said by #Subarata Talukder
give particular folder access permission using storage manager as explained below (without using MANAGE_EXTERNAL_STORAGE permission)
Here I am showing how to access whatsapp statuses programmatically
//give permissions in manifest
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
//give run time permissions

Splashscreen with runtime permissions

I have a splash screen on launching my app. So when showing the splash screen run time permission should show. I got this code below from github. But runtime permissions are not showing. Splash screen works fine, but runtime permission is not working when add this code below. I have added permissions read sms, read external storage, access location. I have given all these permissions in the manifest file also.

You need to call permissioncheck() on onCreate() method after setContentView(). Replace the code provided below with your onCreate() method.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splashfile);
permissioncheck();
}
I removed Handler codes on onCreate() method. Instead, use onRequestPermissionResult() and start LoginActivity from it. Replace the following code to your onRequestPermissionResult().
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
//Checking the request code of our request
if (requestCode == 23) {
//If permission is granted
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
//Displaying a toast
Toast.makeText(this, "Permission granted", Toast.LENGTH_LONG).show();
} else {
//Displaying another toast if permission is not granted
Toast.makeText(this, "Permission Needed To Run The App", Toast.LENGTH_LONG).show();
}
}
if (requestCode == REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS) {
Map<String, Integer> perms = new HashMap<String, Integer>();
// Initial
perms.put(Manifest.permission.READ_EXTERNAL_STORAGE, PackageManager.PERMISSION_GRANTED);
perms.put(Manifest.permission.ACCESS_COARSE_LOCATION, PackageManager.PERMISSION_GRANTED);
perms.put(Manifest.permission.ACCESS_FINE_LOCATION, PackageManager.PERMISSION_GRANTED);
perms.put(Manifest.permission.READ_SMS, PackageManager.PERMISSION_GRANTED);
//Toast.makeText(SplashScreen.this, " Permissions are jddddd", Toast.LENGTH_SHORT).show();
// 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.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED
&& perms.get(Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED &&
perms.get(Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED &&
perms.get(Manifest.permission.READ_SMS) == PackageManager.PERMISSION_GRANTED) {
// All Permissions Granted
// Here start the activity
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {

Android: "Permission Error" on Capture using Camera

In Android the Camera action show a error:
java.lang.SecurityException: Permission Denial: starting Intent { act=android.media.action.IMAGE_CAPTURE cmp=android/com.android.internal.app.ResolverActivity } from ProcessRecord{beb99ec 32121:com.android.hawee/u0a369} (pid=32121, uid=10369) with revoked permission android.permission.CAMERA
at android.os.Parcel.readException(Parcel.java:1620)
I request permission on manifest as follows
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
And on chooserDialog on click of camera
if (ActivityCompat.checkSelfPermission(activity, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE}, Constants.CAMERA_CAPTURE_PERMISSIONS_REQUEST_CODE);
} else {
Intent camera = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
activity.startActivityForResult(camera, Constants.IMAGE_CAPTURE_CAMERA);
}
On activity
#SuppressLint("NewApi")
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
Fragment fragment = getSupportFragmentManager().findFragmentById(R.id.frameContainer);

And on Fragment

startActivityForResult(gallery, Constants.IMAGE_CAPTURE_GALLERY);
} else {

But on click from ChooserDialog always get above error.
How can i ask permission for write to external and Image capture at same time.
If camera n external storage both are required for your app you should || them in if condition.
if (ActivityCompat.checkSelfPermission(activity, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED || ActivityCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE}, Constants.CAMERA_CAPTURE_PERMISSIONS_REQUEST_CODE);
} else {
Intent camera = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
activity.startActivityForResult(camera, Constants.IMAGE_CAPTURE_CAMERA);
}
Try this :-
public static final int REQUEST_ID_MULTIPLE_PERMISSIONS = 1;
in onCreate()
private void checkAndroidVersion() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
checkAndRequestPermissions();
}
}
This method
private boolean checkAndRequestPermissions() {
int camera = ContextCompat.checkSelfPermission(getActivity(),
Manifest.permission.CAMERA);
int wtite = ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.WRITE_EXTERNAL_STORAGE);
int read = ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.READ_EXTERNAL_STORAGE);
List<String> listPermissionsNeeded = new ArrayList<>();
if (wtite != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);
}
if (camera != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.CAMERA);
}
if (read != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.READ_EXTERNAL_STORAGE);
}
if (!listPermissionsNeeded.isEmpty()) {
ActivityCompat.requestPermissions(getActivity(), listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), REQUEST_ID_MULTIPLE_PERMISSIONS);
return false;
}
return true;
}
then use this
#Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
Log.d("in fragment on request", "Permission callback called-------");
switch (requestCode) {
case REQUEST_ID_MULTIPLE_PERMISSIONS: {
Map<String, Integer> perms = new HashMap<>();
// Initialize the map with both permissions
perms.put(Manifest.permission.CAMERA, PackageManager.PERMISSION_GRANTED);
perms.put(Manifest.permission.WRITE_EXTERNAL_STORAGE, PackageManager.PERMISSION_GRANTED);
perms.put(Manifest.permission.READ_EXTERNAL_STORAGE, PackageManager.PERMISSION_GRANTED);
// Fill with actual results from user
if (grantResults.length > 0) {
for (int i = 0; i < permissions.length; i++)
perms.put(permissions[i], grantResults[i]);
// Check for both permissions
if (perms.get(Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED
&& perms.get(Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED && perms.get(Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
Log.d("in fragment on request", "CAMERA & WRITE_EXTERNAL_STORAGE READ_EXTERNAL_STORAGE permission granted");
// process the normal flow
//else any one or both the permissions are not granted
} else {
Log.d("in fragment on request", "Some permissions are not granted ask again ");
//permission is denied (this is the first time, when "never ask again" is not checked) so ask again explaining the usage of permission
// // shouldShowRequestPermissionRationale will return true
//show the dialog or snackbar saying its necessary and try again otherwise proceed with setup.
if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), Manifest.permission.CAMERA) || ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), Manifest.permission.WRITE_EXTERNAL_STORAGE) || ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), Manifest.permission.READ_EXTERNAL_STORAGE)) {
showDialogOK("Camera and Storage Permission required for this app",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
switch (which) {
case DialogInterface.BUTTON_POSITIVE:
checkAndRequestPermissions();
break;
case DialogInterface.BUTTON_NEGATIVE:
// proceed with logic by disabling the related features or quit the app.
break;
}
}
});
}
//permission is denied (and never ask again is checked)
//shouldShowRequestPermissionRationale will return false
else {
Toast.makeText(getActivity(), "Go to settings and enable permissions", Toast.LENGTH_LONG)
.show();
// //proceed with logic by disabling the related features or quit the app.
}
}
}
}
}
}
private void showDialogOK(String message, DialogInterface.OnClickListener okListener) {
new AlertDialog.Builder(getActivity())
.setMessage(message)
.setPositiveButton("OK", okListener)
.setNegativeButton("Cancel", okListener)
.create()
.show();
}
And Finally on button click when u save profile or so
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (!checkAndRequestPermissions()) {
}
else {
// do your stuff here
}
} else {
// do your stuff here
}
Try this code:
For Checking permission I created a separate class as below:
public class MarshMallowPermission {
public static final int RECORD_PERMISSION_REQUEST_CODE = 1;
public static final int EXTERNAL_STORAGE_PERMISSION_REQUEST_CODE = 2;
public static final int CAMERA_PERMISSION_REQUEST_CODE = 3;
Activity activity;
public MarshMallowPermission(Activity activity) {
this.activity = activity;
}
public boolean checkPermissionForRecord(){
int result = ContextCompat.checkSelfPermission(activity, Manifest.permission.RECORD_AUDIO);
if (result == PackageManager.PERMISSION_GRANTED){
return true;
} else {
return false;
}
}
public boolean checkPermissionForExternalStorage(){
int result = ContextCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE);
if (result == PackageManager.PERMISSION_GRANTED){
return true;
} else {
return false;
}
}
public boolean checkPermissionForCamera(){
int result = ContextCompat.checkSelfPermission(activity, Manifest.permission.CAMERA);
if (result == PackageManager.PERMISSION_GRANTED){
return true;
} else {
return false;
}
}
public void requestPermissionForRecord(){
if (ActivityCompat.shouldShowRequestPermissionRationale(activity, Manifest.permission.RECORD_AUDIO)){
Toast.makeText(activity, "Microphone permission needed for recording. Please allow in App Settings for additional functionality.", Toast.LENGTH_LONG).show();
} else {
ActivityCompat.requestPermissions(activity,new String[]{Manifest.permission.RECORD_AUDIO},RECORD_PERMISSION_REQUEST_CODE);
}
}
public void requestPermissionForExternalStorage(){
if (ActivityCompat.shouldShowRequestPermissionRationale(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE)){
Toast.makeText(activity, "External Storage permission needed. Please allow in App Settings for additional functionality.", Toast.LENGTH_LONG).show();
} else {
ActivityCompat.requestPermissions(activity,new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},EXTERNAL_STORAGE_PERMISSION_REQUEST_CODE);
}
}
public void requestPermissionForCamera(){
if (ActivityCompat.shouldShowRequestPermissionRationale(activity, Manifest.permission.CAMERA)){
Toast.makeText(activity, "Camera permission needed. Please allow in App Settings for additional functionality.", Toast.LENGTH_LONG).show();
} else {
ActivityCompat.requestPermissions(activity,new String[]{Manifest.permission.CAMERA},CAMERA_PERMISSION_REQUEST_CODE);
}
}
}
Then
MarshMallowPermission marshMallowPermission = new
MarshMallowPermission(this);
public void getPhotoFromCamera() {
if (!marshMallowPermission.checkPermissionForCamera()) {
marshMallowPermission.requestPermissionForCamera();
} else {
if (!marshMallowPermission.checkPermissionForExternalStorage()) {
marshMallowPermission.requestPermissionForExternalStorage();
} else {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File mediaStorageDir = new File(
Environment.getExternalStorageDirectory()
+ File.separator
+ getString(R.string.directory_name_corp_chat)
+ File.separator
+ getString(R.string.directory_name_images)
);
if (!mediaStorageDir.exists()) {
mediaStorageDir.mkdirs();
}
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss",
Locale.getDefault()).format(new Date());
try {
mediaFile = File.createTempFile(
"IMG_" + timeStamp, /* prefix */
".jpg", /* suffix */
mediaStorageDir /* directory */
);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(mediaFile));
startActivityForResult(takePictureIntent, PICK_FROM_CAMERA);
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
The answer needs more upvotes and should be the official answer about permissions with camera, the other answers don't solved the problem on Android 10.
And how we know, the answers/codes that work on new versions works on olders.
Help us to index this answer:
if (ActivityCompat.checkSelfPermission(activity, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED || ActivityCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE}, Constants.CAMERA_CAPTURE_PERMISSIONS_REQUEST_CODE);
} else {
Intent camera = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
activity.startActivityForResult(camera, Constants.IMAGE_CAPTURE_CAMERA);
}

Android app cache required storage permissions

I have some confusion for the android cache, at run time android app cache required external storage read and write permissions or not. can any one help me for this confusion. For example,
File tempFile = File.createTempFile("img", ".png", getExternalCacheDir());
String imgPath = tempFile.getAbsolutePath();
Try this,
Storage permission
private static final int REQUEST_STORAGE = 112;
if (Build.VERSION.SDK_INT >= 23) {
String[] PERMISSIONS = {android.Manifest.permission.WRITE_EXTERNAL_STORAGE,android.Manifest.permission.READ_EXTERNAL_STORAGE};
if (!hasPermissions(mContext, PERMISSIONS)) {
ActivityCompat.requestPermissions((Activity) mContext, PERMISSIONS, REQUEST_STORAGE );
} else {
File tempFile = File.createTempFile("img", ".png", getExternalCacheDir());
imgPath = tempFile.getAbsolutePath();
}
} else {
File tempFile = File.createTempFile("img", ".png", getExternalCacheDir());
imgPath = tempFile.getAbsolutePath();
}
get Permissions Result
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode) {
case REQUEST_STORAGE: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
File tempFile = File.createTempFile("img", ".png", getExternalCacheDir());
imgPath = tempFile.getAbsolutePath();
}
}
}
}
check permissions for marshmallow
private static boolean hasPermissions(Context context, String... permissions) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null) {
for (String permission : permissions) {
if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
return false;
}
}
}
return true;
}
You have to ask permission at runtime https://developer.android.com/training/permissions/requesting.html, Example,
public void requestPermissionForExternalStorage() {
if (ActivityCompat.shouldShowRequestPermissionRationale(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
Toast.makeText(activity, "External Storage permission needed. Please allow in App Settings for additional functionality.", Toast.LENGTH_LONG).show();
} else {
ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, EXTERNAL_STORAGE_PERMISSION_REQUEST_CODE);
}
}
