Android Kitkat Securityexception When Trying to Read from Mediastore

Android KitKat securityException when trying to read from MediaStore

Had the same problem for the last couple of days. Tried a few solutions, but for some reason I was getting permission denial on Uri content provider for some images even when I had the android.permission.MANAGE_DOCUMENTS permission added to my manifest.

Here's a workaround, for the time being:

i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, CHOOSE_IMAGE);

This forces the older image gallery to open instead of the new Kitkat documents view.

Now, you can get the Uri by calling the following in your onActivityResult:

Uri selectedImageURI = data.getData();

Hope this helps.

Security Exception when open image via Intent.ACTION_VIEW. Lollipop

And the answer is add this flag intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
to ACTION_VIEW intent

READ_EXTERNAL_STORAGE permission for Android

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 String[]{Manifest.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;
}

Sniplet found here: https://developer.android.com/training/permissions/requesting.html

Solutions 2: If it does not work try this:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M
    && ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
        REQUEST_PERMISSION);

return;

}

and then in callback

@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.
    }
}
}

that is from comments. thanks

Android READ_EXTERNAL_STORAGE permission not working

PROBLEM
Your have the error

java.lang.SecurityException: Permission Denial: reading com.android.providers.media.MediaProvider uri content://media/external/images/media/35634 from pid=25240, uid=10070 requires android.permission.READ_EXTERNAL_STORAGE, or grantUriPermission().

CAUSE
You are not giving correctly permissions because of android:maxSdkVersion="18", which according to documentation.

The highest API level at which this permission should be granted to your app. Setting this attribute is useful if the permission your app requires is no longer needed beginning at a certain API level.

As long as you didn't give permissions to API 21 your app is behaving ok.

Check this topic for further info.

SOLUTION
If you wanna give read permissions under API 21, you must declare them as:

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

---

IMPORTANT:

This only make sense when you need to give extra permissions because some old api's require permissions that new versions doesn't, so user experience get's improved because you only ask for certain permissions when needed.

---

So (in this case) the correct way will be:

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

---

ADD ON
If you want to save data you must add WRITE_EXTERNAL_STORAGE permissions.

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