Data not coming to Firebase

When submitting to Firebase, only photos are sent, without text and database as such.
I do according to the guide, but I don’t understand what is the reason.
The guide probably uses the deprecated getDownloadUrl() method, but the photo does not suffer from this. I do not understand the reason for this, since I am still new in this area, please help, I no longer understand what to do. To understand something, look at Maineenter image description here
public class MainActivity extends AppCompatActivity {

User does not have permission to access this object . with storage firebase

I am making an android application which is sort of a social media app
but when I am trying to put image from gallery or from camera for profile or cover this problem occurs.
I want the user to select a photo from his gallery or take a new picture using camera and then upload the image to Firebase Storage.
User does not have permission to access this object using Firebase Storage.
There are my permissions ..
<uses-permission android:name="android.permission.VIBRATE" />

FIrebase Security Rules:
service firebase.storage {

// Allow access by all users
allow read, write;
}
Screenshot of the issue.

Can you please cross check your bucket name if it correct.

After searching i found solution ..
My rules in Firebase was not right ..
we should make it like that ..
service firebase.storage
{ match /b/learno-fc8fc.appspot.com/o
{ match /{allPaths=**}
{ // Allow access by all users
allow read, write; }

How do I play multiple audio files multiple times in android?

But what I want is it should play them like 10 times,
(after e is played, it should again start from a toe)
like from a toe and then again from a toe and then again.....repeat this 10 times
It's like repeating a song in a music player once it is finished, the only difference is I am repeating multiple audio files in a sequence.
I have tried using for loop and while loop but none of them seem to work...
Here is my code

Use media player in the below format
Uri myUri = ....; // initialize Uri here
MediaPlayer mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setDataSource(getApplicationContext(), myUri);
mediaPlayer.prepare();
mediaPlayer.start();
Doing this way you won't have to create 5 different media players. When your first audio file finishes, then in your onCompleteListener, just change the DataSource of the media player and start it again

create an array like this :
private final int[] resID = { R.raw.chimes, R.raw.chord, R.raw.ding,
R.raw.notify, R.raw.recycle, R.raw.ringin, R.raw.ringout,
R.raw.tada };
int from,to,times,songPosition,timesPosition=0;
and then on click
songPosition = from;
play.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
playSong(songPosition);
}
});
private void playSong(int position) {
if (mediaPlayer != null) {
if (mediaPlayer.isPlaying()) {
mediaPlayer.stop();
mediaPlayer.reset();
mediaPlayer.release();
}
}
mediaPlayer = new MediaPlayer();
mediaPlayer = MediaPlayer.create(getApplicationContext(), resID[position]);
mediaPlayer.start();
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
if(timesPosition<times){
if(songsPosition<=to){
songsPosition = songsPosition + 1;
playSong(songsPosition)
}else{
songPosition = from;
timesPosition + timesPosition+1;
playSong(songsPosition)
}
}
}
});
}

SetBackgroundResource() delayed?

I'm implementing Simon Says in Android for a uni project, as part of an Audiogames suite application. I'm trying to generate a random sequence of 5 (just as a starting test) buttons playing and it's all going well except one thing: the buttons don't light up when they should (when their seed in the sequence is generated) but instead they do light up all together at the end of the generation.

So basically what I'm trying to do is generating the sequence by clicking the button "Start" and here's the onClickListener (5 is just for testing purposes)
Button start_button = (Button) findViewById(R.id.game2_start_button);
start_button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
createSequence(5);
}
});
This triggers the createSequence() method as follows
private void createSequence(int i) {
Random rand = new Random();
for(int j = 0; j < i; j++) {
int seed = rand.nextInt(4);
temp.add(seed);
playButton(seed);
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
And so far all good. What I think is failing in my bad programming experience is the PlayButton() method
private void playButton(int i) {
char j;
if(i==0)
j='0';
else if(i==1)
j='1';
else if(i==2)
j='2';
else
j='3';
Button mc_button = (Button) findViewById(R.id.c_button);
Button md_button = (Button) findViewById(R.id.d_button);
Button me_button = (Button) findViewById(R.id.e_button);
Button mf_button = (Button) findViewById(R.id.f_button);
switch(j) {
case '0':
mc_button.setBackgroundResource(R.color.game2_c_on);
//mCMediaPlayer = MediaPlayer.create(Game2PlayActivity.this, R.raw.c_sound);
//mCMediaPlayer.start();
//mCMediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
// #Override
// public void onCompletion(MediaPlayer mp) {
// mCMediaPlayer.release();
// }
//});
break;
case '1':
md_button.setBackgroundResource(R.color.game2_d_on);
//mDMediaPlayer = MediaPlayer.create(Game2PlayActivity.this, R.raw.d_sound);
//mDMediaPlayer.start();
//mDMediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
// #Override
// public void onCompletion(MediaPlayer mp) {
// mDMediaPlayer.release();
// }
//});
break;
case '2':
me_button.setBackgroundResource(R.color.game2_e_on);
//mEMediaPlayer = MediaPlayer.create(Game2PlayActivity.this, R.raw.e_sound);
//mEMediaPlayer.start();
//mEMediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
// #Override
// public void onCompletion(MediaPlayer mp) {
// mEMediaPlayer.release();
// }
//});
break;
case '3':
mf_button.setBackgroundResource(R.color.game2_f_on);
//mFMediaPlayer = MediaPlayer.create(Game2PlayActivity.this, R.raw.f_sound);
//mFMediaPlayer.start();
//mFMediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
// #Override
// public void onCompletion(MediaPlayer mp) {
// mFMediaPlayer.release();
// }
//});
break;
}
}
The Audio Playback is commented but used to work just fine. It's really all about those SetBackgroundResource calls, they don't execute right away but only at the end of the for loop in the CreateSequence method.
If anyone wants to implement the whole project in Android Studio (unrecommended as it's probably very buggy), here it is (25 MB): http://www.mediafire.com/file/2c86sbe3rkb231d/AudiogamesSuite.zip
Thanks in advance
-------------------------------------------------------------------------------
EDIT - Managed to solve it thanks to Martin Pfeffer and some googling. Here's the updated code
private void createSequence(final int i) {
Thread t = new Thread(new Runnable() {
public void run() {
Random rand = new Random();
for (int j = 0; j < i; j++) {
final int seed = rand.nextInt(4);
try {
runOnUiThread(new Runnable() {
#Override
public void run() {
temp.add(seed);
playButton(seed);
}
});
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
});
t.setDaemon(true);
t.start();
}

Add the synchronized specifier to the method.
private synchronized void createSequence(int i) {
// allow only one thread to be executed
}
Edit:
Just saw you do not use separate threads.. So run this code to get the delay:
new Handler().postDelayed(new Runnable(){
public void run() {
// do stuff
}}, 1000 * DELAY_IN_SECONDS);
Edit 2:
I think you are searching for something like this:
import android.os.Bundle;
import android.os.Handler;
import android.os.Looper;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.widget.TextView;
import java.util.concurrent.Callable;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
new MyThread((TextView) findViewById(R.id.textView)).start();
}
class MyThread extends Thread implements Runnable {
TextView textView;
MyThread(TextView textView) {
this.textView = textView;
}
#Override
public void run() {
for (int i = 0; i < 10; i++) {
try {
sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
runOnMainUiThread(new Callable() {
#Override
public Object call() throws Exception {
textView.setText("" + System.currentTimeMillis());
return null;
}
});
}
}
void runOnMainUiThread(final Callable callable) {
new Handler(Looper.getMainLooper()).post(new Runnable() {
#Override
public void run() {
try {
callable.call();
} catch (Exception e) {
Log.e("MyThread", "runOnMainUiThread: ", e);
}
}
});
}
}
}
If you have any question, feel free to ask :)

Buttons not being shown when TextureView is implemented

So I implemented a TextureView through code. Now the buttons however are not being shown, and the onclick listener is giving me a null pointer exception. What am I doing wrong
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_camera);
mTextureView = new TextureView(this);
mTextureView.setSurfaceTextureListener(this);
setContentView(mTextureView);
if (!getPackageManager().hasSystemFeature(PackageManager.FEATURE_CAMERA)){
Toast.makeText(this, "No camera on device", Toast.LENGTH_LONG).show();
}else {
cameraId = findFrontFacingCamera();
if (cameraId<0){
Toast.makeText(this, "no front camera", Toast.LENGTH_LONG).show();
}else{
camera = Camera.open(cameraId);
Toast.makeText(this, "We have camera", Toast.LENGTH_LONG).show();
}
}
findViewById(R.id.buttonMenu).setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
// No account, load new account view
Intent intent = new Intent(CameraActivity.this,
MenuActivity.class);
startActivityForResult(intent, 0);
}
});
}
public void onSurfaceTextureAvailable(SurfaceTexture surface, int width,
int height) {
camera = Camera.open();
Camera.Size previewSize = camera.getParameters().getPreviewSize();
mTextureView.setLayoutParams(new FrameLayout.LayoutParams(
30, 30, Gravity.CENTER));
try {
camera.setPreviewTexture(surface);
} catch (IOException t) {
}
camera.startPreview();
mTextureView.setAlpha(0.8f);
mTextureView.setRotation(45.0f);
}
public void onSurfaceTextureSizeChanged(SurfaceTexture surface, int width,
int height) {
// Ignored, the Camera does all the work for us
}
public boolean onSurfaceTextureDestroyed(SurfaceTexture surface) {
camera.stopPreview();
camera.release();
return true;
}
public void onSurfaceTextureUpdated(SurfaceTexture surface) {
// Called whenever a new frame is available and displayed in the
rotation += 1.0f;
if (rotation > 360) {
rotation = 0;
}
mTextureView.setRotation(rotation);
}
#Override
protected void onPause() {
if (camera != null) {
camera.release();
camera = null;
}
super.onPause();
}
public void onClick(View view) {
if (camera == null){
Toast.makeText(this, "Camera is null", Toast.LENGTH_LONG).show();
}else{
camera.takePicture(null, null,
new PhotoHandler(getApplicationContext(), mPreferences ));
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.camera, menu);
return true;
}
}

you should add the TextureView you created through code in the activity_camera.xml. You should retrieve the root for activity_camera.xml (RelativeLayout) with findViewById and call addView(mTextureView) on the RelativeLayout instance you get. Calling setContentView(mTextureView) will simply replace the views hierarchy.
