READ_EXTERNAL_STORAGE permission for Android










68















I'm trying to access media files (music) on the users device to play them; an easy "hello world"-music player app.



I've followed some tutorials and they basically give the same code. But it won't work; it keeps crashing and telling me:



error.....
Caused by: java.lang.SecurityException: Permission Denial: reading com.android.providers.media.MediaProvider uri content://media/external/audio/media from pid=27696, uid=10059 requires android.permission.READ_EXTERNAL_STORAGE, or grantUriPermission()
....


Now, this is my manifest file:



<?xml version="1.0" encoding="utf-8"?>
<manifest
xmlns:android="http://schemas.android.com/apk/res/android"
package="slimsimapps.troff" >

<uses-permission android:name="android.permission.MEDIA_CONTENT_CONTROL"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>


<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>


This is my Java-method:



public void initialize() 
ContentResolver contentResolver = getContentResolver();
Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
Cursor cursor = contentResolver.query(uri, null, null, null, null);
if (cursor == null)
// query failed, handle error.
else if (!cursor.moveToFirst())
// no media on the device
else
do
addSongToXML(cursor);
while (cursor.moveToNext());




I have tried:



To put this at different places in the manifest file:



<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE”/>


To add android:maxSdkVersion at Read external storage premission:



<uses-permission
android:name="android.permission.READ_EXTERNAL_STORAGE"
android:maxSdkVersion="21" />


To put this in the manifest / application / activity-tag:



android:exported=“true”


To put grantUriPremission between uri and cursro in the javamethod:



grantUriPermission(null, uri, Intent.FLAG_GRANT_READ_URI_PERMISSION);


To use this, it won't crash, but the cursor becomes null:



uri = MediaStore.Audio.Media.getContentUri("EXTERNAL_CONTENT_URI”);


To use INTERNAL content uri, this works as expected, but it only gives "OS-sounds" such as shutter-sound, low-battery-sound, button-click and such:



uri = MediaStore.Audio.Media.INTERNAL_CONTENT_URI;


Pleas help, this should not be a hard problem i know, but i feel like such a beginner!



I have read and tried (or considered them to be not applicable for my problem):



  • Android READ_EXTERNAL_STORAGE permission not working

  • Require permission only for older android versions: maxSdkVersion does not work?

  • Get filename and path from URI from mediastore

  • Android KitKat securityException when trying to read from MediaStore

  • Android: java.lang.SecurityException: Permission Denial: start Intent

  • Strange that error is shown when you have not given this line in manifest <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> are you trying to read some files which is protected by some other apps?

  • @sunilsunny I'm not trying to read som files that are protected, not that I know of anyway, just a simple media player. Yes, I have tried to clean it, i have tried to restart computer, I have tried to generate a signed APK and publish it to google Play and access it as a tester, with no luck....

  • @SharpEdge ; My AVD is the standard Nexus 5, api 23. My module gradle has: compileSdkVersion 23 buildToolsVersion "23.0.0" minSdkVersion 14 targetSdkVersion 23 So i would say 23.

You have two solutions for your problem. The quick one is to lower targetApi to 22 (build.gradle file).
Second is to use new and wonderful ask-for-permission model:



if (checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED)

// Should we show an explanation?
if (shouldShowRequestPermissionRationale(
Manifest.permission.READ_EXTERNAL_STORAGE))
// Explain to the user why we need to read the contacts


requestPermissions(new StringManifest.permission.READ_EXTERNAL_STORAGE,
MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE);

// MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE is an
// app-defined int constant that should be quite unique

return;

    What is MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE ?

    – Solo

You have ask for the permission at run time:



if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M
&& ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED)
ActivityCompat.requestPermissions(this, new StringManifest.permission.READ_EXTERNAL_STORAGE,
REQUEST_PERMISSION);
dialog.dismiss();
return;



And in the callback below you can access the storage without a problem.



@Override
public void onRequestPermissionsResult(final int requestCode, @NonNull final String permissions, @NonNull final int grantResults)
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == REQUEST_PERMISSION)
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
// Permission granted.
else
// User refused to grant permission.

    Step1: add permission on android manifest.xml



    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>


    Step2: onCreate() method



    int permissionCheck = ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE);

    if (permissionCheck != PackageManager.PERMISSION_GRANTED)
    ActivityCompat.requestPermissions(this, new StringManifest.permission.WRITE_EXTERNAL_STORAGE, MY_PERMISSIONS_REQUEST_READ_MEDIA);
    else
    readDataExternal();



    Step3: override onRequestPermissionsResult method to get callback



     @Override
    public void onRequestPermissionsResult(int requestCode, String permissions, int grantResults)
    switch (requestCode)
    case MY_PERMISSIONS_REQUEST_READ_MEDIA:
    if ((grantResults.length > 0) && (grantResults[0] == PackageManager.PERMISSION_GRANTED))
    readDataExternal();

    break;

    default:
    break;




    Note: readDataExternal() is method to get data from external storage.



    Thanks.

    I also had a similar error log and here's what I did-




    1. In onCreate method we request a Dialog Box for checking permissions



      ActivityCompat.requestPermissions(MainActivity.this,
      new StringManifest.permission.READ_EXTERNAL_STORAGE,1);



    2. Method to check for the result



      @Override
      public void onRequestPermissionsResult(int requestCode, String permissions, int grantResults)
      switch (requestCode)
      case 1:
      // If request is cancelled, the result arrays are empty.
      if (grantResults.length > 0
      && grantResults[0] == PackageManager.PERMISSION_GRANTED)
      // permission granted and now can proceed
      mymethod(); //a sample method called

      else

      // permission denied, boo! Disable the
      // functionality that depends on this permission.
      Toast.makeText(MainActivity.this, "Permission denied to read your External storage", Toast.LENGTH_SHORT).show();

      return;

      // add other cases for more permissions

    Please Check below code that using that You can find all Music Files from sdcard :



    public class MainActivity extends Activity

    @Override
    protected void onCreate(Bundle savedInstanceState)
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_animations);
    getAllSongsFromSDCARD();



    public void getAllSongsFromSDCARD()
    String STAR = "*" ;
    Cursor cursor;
    Uri allsongsuri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
    String selection = MediaStore.Audio.Media.IS_MUSIC + " != 0";

    cursor = managedQuery(allsongsuri, STAR, selection, null, null);

    if (cursor != null)
    if (cursor.moveToFirst())
    do
    String song_name = cursor
    .getString(cursor
    .getColumnIndex(MediaStore.Audio.Media.DISPLAY_NAME));
    int song_id = cursor.getInt(cursor
    .getColumnIndex(MediaStore.Audio.Media._ID));

    String fullpath = cursor.getString(cursor
    .getColumnIndex(MediaStore.Audio.Media.DATA));

    String album_name = cursor.getString(cursor
    .getColumnIndex(MediaStore.Audio.Media.ALBUM));
    int album_id = cursor.getInt(cursor
    .getColumnIndex(MediaStore.Audio.Media.ALBUM_ID));

    String artist_name = cursor.getString(cursor
    .getColumnIndex(MediaStore.Audio.Media.ARTIST));
    int artist_id = cursor.getInt(cursor
    .getColumnIndex(MediaStore.Audio.Media.ARTIST_ID));
    System.out.println("sonng name"+fullpath);
    while (cursor.moveToNext());


    cursor.close();







    I have also added following line in the AndroidManifest.xml file as below:



    <uses-sdk
    android:minSdkVersion="16"
    android:targetSdkVersion="17" />

    <uses-permission android:name="android.permission.MEDIA_CONTENT_CONTROL" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

    • Thanks, I have tried something similar before, but I tried your code and it crashes on "cursor = managedQuery(allsongsuri, STAR, selection, null, null);", same error as before. By the way; managedQuery is deprecated, but it still crashes if i change it to "contentResolver.query", which have the same input parameters...

    In addition of all answers.
    You can also specify the minsdk to apply with this annotation



    @TargetApi(_apiLevel_)


    I used this in order to accept this request even my minsdk is 18. What it does is that the method only runs when device targets "_apilevel_" and upper.
    Here's my method:



     @TargetApi(23)
    void solicitarPermisos()

    if (ContextCompat.checkSelfPermission(this,permiso)
    != PackageManager.PERMISSION_GRANTED)

    // Should we show an explanation?
    if (shouldShowRequestPermissionRationale(
    Manifest.permission.READ_EXTERNAL_STORAGE))
    // Explain to the user why we need to read the contacts


    requestPermissions(new StringManifest.permission.READ_EXTERNAL_STORAGE,
    1);

    // MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE is an
    // app-defined int constant that should be quite unique

      You have two solutions for your problem. The quick one is to lower targetApi to 22 (build.gradle file).
      Second is to use new and wonderful ask-for-permission model:



      if (checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE)
      != PackageManager.PERMISSION_GRANTED)

      // Should we show an explanation?
      if (shouldShowRequestPermissionRationale(
      Manifest.permission.READ_EXTERNAL_STORAGE))
      // Explain to the user why we need to read the contacts


      requestPermissions(new StringManifest.permission.READ_EXTERNAL_STORAGE,
      MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE);

      // MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE is an
      // app-defined int constant that should be quite unique

      return;

      You have ask for the permission at run time:



      if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M
      && ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED)
      ActivityCompat.requestPermissions(this, new StringManifest.permission.READ_EXTERNAL_STORAGE,
      REQUEST_PERMISSION);
      dialog.dismiss();
      return;



      And in the callback below you can access the storage without a problem.



      @Override
      public void onRequestPermissionsResult(final int requestCode, @NonNull final String permissions, @NonNull final int grantResults)
      super.onRequestPermissionsResult(requestCode, permissions, grantResults);
      if (requestCode == REQUEST_PERMISSION)
      if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
      // Permission granted.
      else
      // User refused to grant permission.

              I also had a similar error log and here's what I did-




              1. In onCreate method we request a Dialog Box for checking permissions



                ActivityCompat.requestPermissions(MainActivity.this,
                new StringManifest.permission.READ_EXTERNAL_STORAGE,1);



              2. Method to check for the result



                @Override
                public void onRequestPermissionsResult(int requestCode, String permissions, int grantResults)
                switch (requestCode)
                case 1:
                // If request is cancelled, the result arrays are empty.
                if (grantResults.length > 0
                && grantResults[0] == PackageManager.PERMISSION_GRANTED)
                // permission granted and now can proceed
                mymethod(); //a sample method called

                else

                // permission denied, boo! Disable the
                // functionality that depends on this permission.
                Toast.makeText(MainActivity.this, "Permission denied to read your External storage", Toast.LENGTH_SHORT).show();

                return;

              • Thanks, I have tried something similar before, but I tried your code and it crashes on "cursor = managedQuery(allsongsuri, STAR, selection, null, null);", same error as before. By the way; managedQuery is deprecated, but it still crashes if i change it to "contentResolver.query", which have the same input parameters...

              You can also specify the minsdk to apply with this annotation



              @TargetApi(_apiLevel_)


              I used this in order to accept this request even my minsdk is 18. What it does is that the method only runs when device targets "_apilevel_" and upper.
              Here's my method:



               @TargetApi(23)
              void solicitarPermisos()

              if (ContextCompat.checkSelfPermission(this,permiso)
              != PackageManager.PERMISSION_GRANTED)

              // Should we show an explanation?
              if (shouldShowRequestPermissionRationale(
              Manifest.permission.READ_EXTERNAL_STORAGE))

                  In addition of all answers.
                  You can also specify the minsdk to apply with this annotation



                  @TargetApi(_apiLevel_)


                  I used this in order to accept this request even my minsdk is 18. What it does is that the method only runs when device targets "_apilevel_" and upper.
                  Here's my method:



                   @TargetApi(23)
                  void solicitarPermisos()

                  if (ContextCompat.checkSelfPermission(this,permiso)
                  != PackageManager.PERMISSION_GRANTED)

                  // Should we show an explanation?
                  if (shouldShowRequestPermissionRationale(
                  Manifest.permission.READ_EXTERNAL_STORAGE))
                  // Explain to the user why we need to read the contacts


                  requestPermissions(new StringManifest.permission.READ_EXTERNAL_STORAGE,
                  1);

                  // MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE is an
                  // app-defined int constant that should be quite unique

                  return;
