Android. How To Determine The Type Of Media File In Onactivityresult()?

I get media file from Gallery. Intent intent = new Intent(Intent.ACTION_GET_CONTENT); intent.setType('image/*,video/*,audio/*'); startActivityForResult(Inte

Solution 1:

Try this:

ContentResolvercr=this.getContentResolver();
Stringmime= cr.getType(uri);

Solution 2:

Just for reference, in Kotlin we can create an extension function for this.

fun Activity.getMimeType(uri:Uri?):String?{
    this.let {
        val cr: ContentResolver = it.contentResolver
        if (uri == null) returnnullreturn cr.getType(uri)?:null
    }
    
}

Feel free to replace nulls with empty String or something. but this works fines!
