Android: How to Display a Bitmap in a WebView?

Question

I\'m using a WebView for displaying a map-like image, due to the built-in panning and zooming functionality. However, I need to overlay some other information (markers etc)

Answer 1

You don't need placeholder if u want to load image in webview

You can directly load the dataurl in the webview. For ex:

ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, byteArrayOutputStream);
byte[] byteArray = byteArrayOutputStream.toByteArray();
String imgageBase64 = Base64.encodeToString(byteArray, Base64.DEFAULT);
    String dataURL= "data:image/png;base64," + imgageBase64;

webview.loadUrl(dataURL); //pass the bitmap base64 dataurl in URL parameter

Hope it helps others! :-)
