Unable to set image source when accessing image from gallery-Android

Question

Iam using cordova 3.4. When i capture an image and set it,its working fine but when I try to access on image from gallery I get the url

content://com.androi         


        

Answer 1

Whenever some uri is passed into 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.
