Saving image from url using Picasso?
I Modified the solution to this, adding permissions and a button to load and save the Image,and PhotoLoader class remains the same !
private static final String[] STORAGE_PERMISSIONS = { Manifest.permission.WRITE_EXTERNAL_STORAGE};
ImageView imageView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imageView = (ImageView) findViewById(R.id.imageView);
verifyPermissions();
}
public void save(View view)
{
Picasso.with(this)
.load("https://www.w3schools.com/howto/img_fjords.jpg")
.into(new PhotoLoader("myImg.jpg" , imageView));
}
public void verifyPermissions()
{
// This will return the current Status
int permissionExternalMemory = ActivityCompat.checkSelfPermission(MainActivity.this,Manifest.permission.WRITE_EXTERNAL_STORAGE);
if(permissionExternalMemory != PackageManager.PERMISSION_GRANTED)
{
// If permission not granted then ask for permission real time.
ActivityCompat.requestPermissions(MainActivity.this,STORAGE_PERMISSIONS,1);
}
}
Solved. now works fine!
I did
//save image
public static void imageDownload(Context ctx, String url){
Picasso.with(ctx)
.load("http://blog.concretesolutions.com.br/wp-content/uploads/2015/04/Android1.png")
.into(getTarget(url));
}
//target to save
private static Target getTarget(final String url){
Target target = new Target(){
@Override
public void onBitmapLoaded(final Bitmap bitmap, Picasso.LoadedFrom from) {
new Thread(new Runnable() {
@Override
public void run() {
File file = new File(Environment.getExternalStorageDirectory().getPath() + "/" + url);
try {
file.createNewFile();
FileOutputStream ostream = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 80, ostream);
ostream.flush();
ostream.close();
} catch (IOException e) {
Log.e("IOException", e.getLocalizedMessage());
}
}
}).start();
}
@Override
public void onBitmapFailed(Drawable errorDrawable) {
}
@Override
public void onPrepareLoad(Drawable placeHolderDrawable) {
}
};
return target;
}
I can see 2 possible issues:
- trying to save to external storage without write permissions in your manifest
- try change the filename so its not the whole url, which could be your issue because of the characters in your url that arent valid as filename chars.
