回答
注意 task.getResult().getDownloadUrl()
现在已弃用，可以替换以下部分代码
filePath.putFile(resultUri).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
@Override
public void onComplete(@NonNull final Task<UploadTask.TaskSnapshot> task)
{
if(task.isSuccessful())
{
Toast.makeText(SetupActivity.this, "Profile Image stored successfully...", Toast.LENGTH_SHORT).show();
final String downloadUrl = task.getResult().getDownloadUrl().toString();
有
filePath.putFile(resultUri)
.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
@Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
final Task<Uri> firebaseUri = taskSnapshot.getStorage().getDownloadUrl();
firebaseUri.addOnSuccessListener(new OnSuccessListener<Uri>() {
@Override
public void onSuccess(Uri uri) {
final String downloadUrl = uri.toString();
// complete the rest of your code
}
});
}
});
