required android.permission Read_External_storage, or grantUrlPermissions error

Question

I think my permissions properly located on AndroidManifest.xml.

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

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="23" />


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

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

            </intent-filter>
        </activity>


        <activity android:name=".NextActivity"
            android:label="This is next_activity"/>
    </application>

</manifest>

I have "android.permission.READ_EXTERNAL_STORAGE" and "android.permission.WRITE_EXTERNAL_STORAGE" right after manifest.

but the error is keep occured.

Caused by: java.lang.SecurityException: Permission Denial: reading com.android.providers.media.MediaProvider uri content://media/external/images/media/40 from pid=2473, uid=10073 requires android.permission.READ_EXTERNAL_STORAGE, or grantUriPermission()

and this is my MainActivity.java

public class MainActivity extends AppCompatActivity {

public static final int IMAGE_GALLERY_REQUEST = 20;
Button btnStart;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
   }

public void gallery_open(View view) {
    Intent galleryPickerIntent = new Intent(Intent.ACTION_PICK);
    File pictureDirectory = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
    String pictureDirectoryPath = pictureDirectory.getPath();
    Uri data = Uri.parse(pictureDirectoryPath);
    galleryPickerIntent.setDataAndType(data,"image/*");
    startActivityForResult(galleryPickerIntent, IMAGE_GALLERY_REQUEST);




}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent){
    super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
    if(resultCode == Activity.RESULT_OK){
        if(requestCode ==  IMAGE_GALLERY_REQUEST) {
            onSelectedFromGalleryResult(imageReturnedIntent);
        }
    }

}

private void onSelectedFromGalleryResult(Intent data){
    Bitmap bm  = null;
    if(data != null){
        try{
            bm = MediaStore.Images.Media.getBitmap(getApplicationContext().getContentResolver(), data.getData());
        }catch(IOException e){
            e.printStackTrace();
        }
        //ivImage.setImageBitmap(bm);
        ImageView imgView = (ImageView)findViewById(R.id.ivImage);
        imgView.setImageBitmap(bm);


    }
}

you need to ask run time permission – AskNilesh Jul 06 '17 at 07:24 — AskNilesh, Jul 06 '17 at 07:24

James I suppose you are facing this error on Android 6.0 or onwards. You need to handle the permissions explicitly in these versions. Please find the android developer link

You need to provide the run time permission for android marshmallow version

You can add this code in onCreate() or any click events, try this:

     if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1){
            //    requestPermission();
            requestAppPermissions(new String[]{
                    Manifest.permission.READ_EXTERNAL_STORAGE,Manifest.permission.WRITE_EXTERNAL_STORAGE },
                    R.string.app_name, REQUEST_PERMISSIONS);

            //this code will be executed on devices running ICS or later
        }

also add this function for requesting the run time permission

   public void requestAppPermissions(final String[] requestedPermissions,
                                          final int stringId, final int requestCode) {
            mErrorString.put(requestCode, stringId);
            int permissionCheck = PackageManager.PERMISSION_GRANTED;
            boolean shouldShowRequestPermissionRationale = false;
            for (String permission : requestedPermissions) {
                permissionCheck = permissionCheck + ContextCompat.checkSelfPermission(this, permission);
                shouldShowRequestPermissionRationale = shouldShowRequestPermissionRationale || ActivityCompat.shouldShowRequestPermissionRationale(this, permission);
            }
            if (permissionCheck != PackageManager.PERMISSION_GRANTED) {
                if (shouldShowRequestPermissionRationale) {
                    Snackbar.make(findViewById(android.R.id.content), stringId,
                            Snackbar.LENGTH_INDEFINITE).setAction("GRANT",
                            new View.OnClickListener() {
                                @Override
                                public void onClick(View v) {
                                    ActivityCompat.requestPermissions(DashBoardActivity.this, requestedPermissions, requestCode);
                                }
                            }).show();
                } else {
                    ActivityCompat.requestPermissions(this, requestedPermissions, requestCode);
                }
            } else {
                onPermissionsGranted(requestCode);
            }
        }

This function is called when the permission is granted and you can read the internal and external storage

public void onPermissionsGranted(final int requestCode) {
        Toast.makeText(this, "Permissions Received.", Toast.LENGTH_LONG).show();
    }

The below code for checking the requested permission result

  @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        int permissionCheck = PackageManager.PERMISSION_GRANTED;
        for (int permission : grantResults) {
            permissionCheck = permissionCheck + permission;
        }
        if ((grantResults.length > 0) && permissionCheck == PackageManager.PERMISSION_GRANTED) {
            onPermissionsGranted(requestCode);
        } else {
            Snackbar.make(findViewById(android.R.id.content), mErrorString.get(requestCode),
                    Snackbar.LENGTH_INDEFINITE).setAction("ENABLE",
                    new View.OnClickListener() {
                        @Override
                        public void onClick(View v) {

                        }
                    }).show();
        }
    }
