Storage permission error in Marshmallow

Question

In Lollipop  the download functionality works fine in my app  but when I upgraded to Marshmallow  my app crashes and gives this error when I try to download from the internet into the SD card    Neither user  nor current process has android permission WRITE EXTERNAL STORAGE   It complains about this line of code    DownloadManager manager    DownloadManager  getSystemService Context DOWNLOAD SERVICE   manager enqueue request     I have the permissions in the manifest outside application    lt uses-permission android name  android permission INTERNET    gt   lt uses-permission android name  android permission WRITE EXTERNAL STORAGE    gt   lt uses-permission android name  android permission WAKE LOCK    gt    I cleaned and rebuilt the project  but it still crashes

Before starting your download check your runtime permissions and if you don't have permission the request permissions like this method

requestStoragePermission()

private void requestStoragePermission(){
    if (ActivityCompat.shouldShowRequestPermissionRationale(this, 
                android.Manifest.permission.READ_EXTERNAL_STORAGE))
        {

        }

        ActivityCompat.requestPermissions(this, 
            new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
            STORAGE_PERMISSION_CODE);
}

@Override
public void onRequestPermissionsResult(int requestCode, 
                @NonNull String[] permissions, 
                @NonNull int[] grantResults) {

    if(requestCode == STORAGE_PERMISSION_CODE){
        if(grantResults.length >0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){
        }
        else{
            Toast.makeText(this,
                           "Oops you just denied the permission", 
                           Toast.LENGTH_LONG).show();
        }
    }
}

Seems user has declined the permission and app tries to write to external disk   causing error    Override public void onRequestPermissionsResult int requestCode          String permissions    int   grantResults        switch  requestCode            case MY PERMISSIONS REQUEST READ CONTACTS                   If request is cancelled  the result arrays are empty              if  grantResults length  gt  0                  amp  amp  grantResults 0     PackageManager PERMISSION GRANTED                        permission was granted  yay  Do the                    contacts-related task you need to do                 else                       permission denied  boo  Disable the                    functionality that depends on this permission                            return                        other  case  lines to check for other            permissions this app might request           Check https   developer android com training permissions requesting html  This video will give you a better idea about UX  handling Runtime permissions https   www youtube com watch v iZqDdvhTZj0

Unless there is a definite requirement of writing on external storage  you can always choose to save files in app directory  In my case I had to save files and after wasting 2 to 3 days I found out if I change the storage path from  Environment getExternalStorageDirectory     to   getApplicationContext   getFilesDir   getPath     which returns the internal app files directory path   it works like charm on all the devices  This is because for writing on External storage you need extra permissions but writing in internal app directory is simple

In a simple way the permission can be granted using manifest xml file  but it was ok till the api level 23 sdk version 6  after from here  if we want to get the permission we have to ask for the use to allow the permission which are needed   Just add this code in the mainActivity java  Override             public void onClick View view                       Request the permission                 ActivityCompat requestPermissions MainActivity this                          new String   Manifest permission CAMERA                           PERMISSION REQUEST CAMERA     Replace CAMERA or add with WRITE EXTERNAL STORAGE if you want  and with the unique code                               new String   Manifest permission CAMERA  Manifest permission WRITE EXTERNAL STORAGE                       101     This is the simple code to get permission

Android s permission system is one of the biggest security concern all   along since those permissions are asked for at install time  Once   installed  the application will be able to access all of things   granted without any user s acknowledgement what exactly application   does with the permission       Android 6 0 Marshmallow introduces one of the largest changes to the   permissions model with the addition of runtime permissions  a new   permission model that replaces the existing install time permissions   model when you target API 23 and the app is running on an Android 6 0    device   Courtesy goes to Requesting Permissions at Run Time    Example   Declare this as Global  private static final int PERMISSION REQUEST CODE   1    Add this in your onCreate   section   After  setContentView R layout your xml     if  Build VERSION SDK INT  gt   23                if  checkPermission                             Code for above or equal 23 API Oriented Device                 Your Permission granted already  Do next code           else               requestPermission       Code for permission                   else                  Code for Below 23 API Oriented Device            Do next code         Now adding  checkPermission   and requestPermission     private boolean checkPermission         int result   ContextCompat checkSelfPermission Your Activity this  android Manifest permission WRITE EXTERNAL STORAGE       if  result    PackageManager PERMISSION GRANTED            return true        else           return false           private void requestPermission          if  ActivityCompat shouldShowRequestPermissionRationale Your Activity this  android Manifest permission WRITE EXTERNAL STORAGE             Toast makeText Your Activity this   Write External Storage permission allows us to do store images  Please allow this permission in App Settings    Toast LENGTH LONG  show          else           ActivityCompat requestPermissions Your Activity this  new String   android Manifest permission WRITE EXTERNAL STORAGE   PERMISSION REQUEST CODE             Override public void onRequestPermissionsResult int requestCode  String permissions    int   grantResults        switch  requestCode            case PERMISSION REQUEST CODE              if  grantResults length  gt  0  amp  amp  grantResults 0     PackageManager PERMISSION GRANTED                    Log e  value    Permission Granted  Now you can use local drive                    else                   Log e  value    Permission Denied  You cannot use local drive                                break            FYI  onRequestPermissionsResult     This interface is the contract for receiving the results for   permission requests
