Save image to sdcard in Android
Question
I have a ImageView and a WebView where I am trying to show the same image.
I have downloaded the image with picasso and all works well during the download.
When I save the image into sdcard to show into a ImageView and into WebView I have a problem: My ImageView allways shows the last image downloaded and this is ok. But, after I save the image to show into WebView, my WebView always shows the first image downloaded and not the last downloaded.
Please, what am I doing wrong?
public void downloadimage(){
Bitmap bm=MyGetImage(1);
saveImageToExternalStorageToShow(bm);
bm=MyGetImage(2);
saveImageToExternalStorageToShow(bm);//into this method, webview doesn´t show image correctly
}
public void saveImageToExternalStorageToShow(Bitmap image) {
String fullPath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/";
try
{
ImageView imv= (ImageView) getActivity().findViewById(R.id.ImvTeste);
//ok-shows the image downloaded
imv.setImageBitmap(image);
File dir = new File(fullPath);
if (!dir.exists()) {
dir.mkdirs();
}
OutputStream fOut = null;
String fileName = "sala.jpg"; //DateFormat.format("dd_MM_yyyy_hh_mm_ss", System.currentTimeMillis()).toString();
File file = new File(fullPath, fileName);
boolean b=false;
if(!file.exists()) {
b=file.createNewFile();
} else {
b=file.delete();
b=file.createNewFile();
}
fOut = new FileOutputStream(file);
image.compress(Bitmap.CompressFormat.JPEG, 80, fOut);
fOut.flush();
fOut.close();
String imagePath = Uri.fromFile(file).toString();//"file://"+ base + "/test.jpg";
String html = "<html><head></head><body><img src=\""+ imagePath + "\"></body></html>";
//Problem here-wedview allways shows the first image downloaded
webView.loadDataWithBaseURL("", html, "text/html", "utf-8", "");
}
catch (Exception e)
{
Log.e("saveToExternalStorage()", e.getMessage());
}
}

This is likely due to the image being cached in the WebView.
Try calling webView.clearCache(true) before showing the second image and it should work propperly.
