cordova-plugin-android-mediastore

This simple Cordova plugin converts a base64 image/png bytestring to an image file and adds it to the gallery.

Tested on Android APIs 22(5.1 Lollipop), 29(10 Q) and 30(11 R).

Useful when capturing an HTML canvas.

API

The plugin exports only one function:

//CordovaAndroidMediaStore.js

/**
 * @param byteString the bytestring part of the base64 dataURI (excludes the MIME part, see the example)
 * @param fileDir the relative directory to save the file to.
 * @param fileName 
 */
exports.store = function (byteString, fileDir, fileName, success, error) {
    exec(success, error, 
        'CordovaAndroidMediaStore', 
        'store', 
        [byteString, fileDir, fileName]);
};

example

let dataURItoGallery: (dataURI: string) => Blob = (dataURI) => {
    // Get bytestring part of the image dataURI
    let byteString = dataURI.split(",")[1];
    cordova.plugins.CordovaAndroidMediaStore.store(byteString, "Pictures", `${Date.now()}.png`);
};
