I am working on a very basic app which captures a photo using the phone's camera and sets it up on the ImageView. But the code is not entering the if(resultCode==Activity.RESULT_OK) statement. I understood this by using Log inside the if statement. Any idea how I can resolve this? Here is the onActivityResult()
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if(resultCode==Activity.RESULT_OK){
Log.v("cam"," resultCode");
Bundle extras=data.getExtras();
bmp=(Bitmap) extras.getParcelable("data");
iv.setImageBitmap(bmp);
button1.setText("Take Another");
}
}
first of all
Check that u have all the necessary permission in the manifest file for capturing the image and where you're storing that image that folder access.
Check it out for more reference. for reference
Try This ... It works for Me..
if ( resultCode == Activity.RESULT_OK ) {
Uri path = data.getData();
try {
bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(),path);
imgView.setImageBitmap(bitmap);
imgView.setVisibility(View.VISIBLE);
Name.setVisibility(View.VISIBLE);
} catch (IOException e) {
e.printStackTrace();
}
}

I use a WebView on my Xamarin app, and I use it without any problem. but I can't use browse file on my phone for select file. I click button but I don't see any action. that is work on my web site, but I can't use it on my phone app.
On my web
You can check this code and use the new Uri[].
protected override void OnActivityResult(int requestCode, Result resultCode, Intent intent)
{
if (requestCode == FILECHOOSER_RESULTCODE)
{
if (null == mUploadMessage) return;
Android.Net.Uri result = intent.Data;
mUploadMessage.OnReceiveValue(new Uri[] { result });
mUploadMessage = null;
}
}
How to know FirebaseRecyclerAdapter query is zero or not, exist or not
I find some instructions on
https://github.com/firebase/FirebaseUI-Android/tree/master/database
it says:
Data and error events
When using the FirebaseRecyclerAdapter you may
want to perform some action every time data changes or when there is
an error. To do this, override the onDataChanged() and onError()
methods of the adapter:
FirebaseRecyclerAdapter adapter = new FirebaseRecyclerAdapter<Chat, ChatHolder>(options) {
// ...
#Override
public void onDataChanged() {
// Called each time there is a new data snapshot. You may want to use this method
// to hide a loading spinner or check for the "no documents" state and update your UI.
// ...
}
#Override
public void onError(DatabaseError e) {
// Called when there is an error getting data. You may want to update
// your UI to display an error message to the user.
// ...
}
};
When I tried to use as follow:
mAdapter = new FirebaseRecyclerAdapter<Place, PlaceViewHolder>(options)
{
#Override
public void onDataChanged(DataSnapshot dataSnapshot)
{
// Called each time there is a new data snapshot. You may want to use this method
// to hide a loading spinner or check for the "no documents" state and update your UI.
// ...
if (dataSnapshot.exists())
{
Log.d(TAG,"data exists");
}
else
{
Log.d(TAG,"No data exists");
}
}
#NonNull
#Override
public PlaceViewHolder onCreateViewHolder(#NonNull ViewGroup viewGroup, int i)
{
Error message is:
Method does not override method from its superclass
So how can I solve this problem, Thank you.
I found the answer from another page:
https://www.programcreek.com/java-api-examples/?api=com.firebase.ui.database.FirebaseRecyclerAdapter
#Override
public void onDataChanged()
{
// Called each time there is a new data snapshot. You may want to use this method
// to hide a loading spinner or check for the "no documents" state and update your UI.
// ...
if (getItemCount() == 0)
{
Log.d(TAG,"No data exists");
}
else
{
Log.d(TAG,"data exists");
}
}
So far in my social media app, the user's data such as first name, last name, email, gender, and more can be saved in a firebase database and retrieved when needed. As of today, I got a working profile picture when first creating a profile you can tap on the empty profile picture icon and it loads up your gallery replacing it with whatever image the user chooses.
Although this is quite neat I need to be able to upload this image somehow under the Users node in my firebase database. I am quite lost when it comes to converting the bitmap data and after reading through some documentation it still confuses me. Below is my code for using a locally saved photo replacing it as the profile picture to show what I have so far.
#Override
public void onClick(View view)
{
if (view == profilePicture)
{
//Toast.makeText(this, "We made it to the onClick for image!", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 0);
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK)
{
Uri targetUri = data.getData();
Bitmap bitmap;
try
{
bitmap = BitmapFactory.decodeStream(getContentResolver().openInputStream(targetUri));
profilePicture.setImageBitmap(bitmap);
}
catch (FileNotFoundException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
The onClick method runs after the user taps the profile icon. Now I will show you the database I am currently working with, this is the Firebase real-time database, not the Firebase storage. While firebase storage might be more appropriate I can't seem to figure out how to tell whos photo would be who as it does not upload them with a user id associated with them.
Database Picture Here
Instead of uploading a bitMap, a far better solution for a simple problem like yours would be Firebase Storage, similar to the Database but you can upload files such as images with much ease.
Here are the methods I currently use in my app:
private void chooseImage() {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);
}
private void uploadImage() {
if(filePath != null)
{
final ProgressDialog progressDialog = new ProgressDialog(this);
progressDialog.setTitle("Uploading...");
progressDialog.show();
StorageReference ref = storageReference.child("images/"+userID);
ref.putFile(filePath)
.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
progressDialog.dismiss();
toastMessage("Uploaded");
}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
progressDialog.dismiss();
toastMessage("Failed"+e.getMessage());
}
})
.addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
#Override
public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
double progress = (100.0*taskSnapshot.getBytesTransferred()/taskSnapshot
.getTotalByteCount());
progressDialog.setMessage("Uploaded "+(int)progress+"%");
}
});
}
}
I have a scenario in which I want to move my top level, in other words first, collection to the third level. Is the only way to go about this to use third party import-export software with manipulation to do this, or is there a firestore feature that I am missing?
All help will be greatly appreciated.
TopLevel>Documents>ThirdLevel, where top level is the first collection in the db. Just to give a better picture of what I am trying to say.
Firestore has no ability to move collections or documents. Instead, you can copy documents. You'll have to write code to read the contents of a document, then write those contents to a document in a new location, then delete the original document.
I know it's an old question, but just in case someone else needs this. It's now possible using google's cloud shell.
Details available in this link:
https://firebase.google.com/docs/firestore/manage-data/export-import
You have two options to export specific collections, modify them, then import them, or export the whole bucket, then import it back. As I understood you can't mix the operations for example export all and import specific collections.
Note: I believe you'll be charged for the read and write of all documents exported and imported. And billing must be activated.
maybe this can help
public void moveFirestoreDocument(DocumentReference fromPath, final DocumentReference toPath) {
fromPath.get().addOnCompleteListener(new OnCompleteListener<DocumentSnapshot>() {
#Override
public void onComplete(#NonNull Task<DocumentSnapshot> task) {
if (task.isSuccessful()) {
DocumentSnapshot document = task.getResult();
if (document != null) {
toPath.set(document.getData())
.addOnSuccessListener(new OnSuccessListener<Void>() {
#Override
public void onSuccess(Void aVoid) {
Log.d(TAG, "DocumentSnapshot successfully written!");
fromPath.delete()
.addOnSuccessListener(new OnSuccessListener<Void>() {
#Override
public void onSuccess(Void aVoid) {
Log.d(TAG, "DocumentSnapshot successfully deleted!");
}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Log.w(TAG, "Error deleting document", e);
}
});
}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Log.w(TAG, "Error writing document", e);
}
});
} else {
Log.d(TAG, "No such document");
}
} else {
Log.d(TAG, "get failed with ", task.getException());
}
}
});
}
I'm trying to make the Google Translate App using Google jar file. I have added external .jar files called google-api-translate-java-0.97 into my android project.
My code is as following
public class MainActivity extends Activity
{
String text;
//#SuppressWarnings("deprecation")
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try
{
TranslateV2.setHttpReferrer("http://code.google.com/p/google-api-translate-java/");
text = Translate.DEFAULT.execute("hello", Language.ENGLISH, Language.MARATHI);
Toast.makeText(MainActivity.this, text, Toast.LENGTH_LONG).show();
} catch (GoogleAPIException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
Im getting errors as below:
Could not find method com.google.api.translate.TranslateV2.setHttpReferrer, referenced from method com.example.translator.MainActivity.onCreate
java.lang.VerifyError: com/example/translator/MainActivity
Please help me to make successful translator App using another method if your have any.
