Webview App Permission For Capturing Images Using Camera And Uploading Images From Gallery

which code I have to put for allowing to take pictures using camera and uploading images from gallery in android webview app and where should I put it.

Solution 1:

Add in Manifest.xml:

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

For android versions higher than M you have to ask for permissions, I'm referring to this question:

Solution 2:

In webview you don't need any permission.
