Enforce PNGs about tvapprepo HOT 2 CLOSED

this was never closed...so just offering more advice.

create a public static boolean method to check the image file extension before its being uploaded & if it returns true then continue on in the process..however if it returns false...issue a toast or dialog message stating its the wrong file...but...if the file can be converted beforehand I think that would be a better option.
such as: very rough example & can be better
(i would suggest to use an asynctask)
public static void convert2PNG(filename){
try {
FileOutputStream out = new FileOutputStream(filename);
bmp.compress(Bitmap.CompressFormat.PNG, 100, out); //100-best quality
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
//is image a png?
public static boolean isPNG(File file/String string){
File f = new File(file);
String s = string;
String ext = f.getAbsolutePath().substring(f.getAbsolutePath().lastIndexOf("."));
//or
String ext = s.substring(s.lastIndexOf("."));

if(ext.equalsIgnoreCase("png"){
return true;
}else{
return false;
}
if you allow users to use their own banners/logos then you should convert the images to PNG to make it easier for your users & speed up the process even further if they downloaded the wrong format.

This was meant more for my own generating mechanism. Since we've moved away from that, this can be closed without fix
