copy a picture from android photo-library causes error

get this error when I try to resolve the local filesystem uri by phonegap:

java.lang.SecurityException: Permission Denial: reading com.android.providers.media.MediaDocumentsProvider

I use the camera to access the photo-library and receive this file_uri:

content://com.android.providers.media.documents/document/image%3A355

Then I try to access the local filesystem:

window.resolveLocalFileSystemURI(file_uri, function(a){console.log("success");}, function(b){console.log("fail");});

That's where I receive this error:

Btw.: I tried this scenario on iOS and it works without a problem.

AndroidManifest.xml:

Here is a simple fix to this problem:

replace this:

content://com.android.providers.media.documents/document/image%3A352

by this:

content://com.android.providers.media.documents/document/image%253A352

if you are using JavaScript you can use this code:

var path = content://com.android.providers.media.documents/document/image%3A352;
path = path.replace("%", "%25");

this technique force the uri to let pass "%3A" as it is, without changing it to ":",

Whenever some uri is passed into <img src="uri" /> it's implicitly decoded from

content://com.android.providers.media.documents/document/image%3A9888 (1)

into

content://com.android.providers.media.documents/document/image:9888 (2)

However, after returning from Intent.ACTION_OPEN_DOCUMENT or Intent.ACTION_GET_CONTENT Android provides you with the read permission for (1), not (2). In this case WebView will expectantly log an error:

java.lang.SecurityException: Permission Denial: reading com.android.providers.media.MediaDocumentsProvider uri content://com.android.providers.media.documents/document/image:9888 from pid=13163, uid=10165 requires android.permission.MANAGE_DOCUMENTS, or grantUriPermission()

or

Unable to open content URL

Code snippet

All you need to resolve the issue is 

    String uriToUseInWebView = transformForWebView(uri.toString());

    private String transformForWebView(String uri) {
        for (int i = 0; i < timesDecodingWebView(); i++)
            uri = uri.replace("%", Uri.encode("%"));
        return uri;
    }

    private int timesDecodingWebView() {
        if (Build.VERSION.RELEASE.equals("4.4.2")) {
            return 2;
        } else {
            return 1;
        }
    }

in your Java code before passing uri into HTML/JS to ensure that (1) will be actually loaded.

I've tested that on 4.4.2, 4.4.4 and 5.0. The funny part is that Android 4.4.2 decodes the uri internally twice.

Have you tried to add the correct permission to manifest.xml?

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