I have 3 page application, in which the activities change every 10 secs (i.e., Activity1 -> Activity2 -> Activity3 -> Activity1 .......).
I have a progressbar in Activity2 which updates every 1 sec. The problem is, whenever the Activity2 is changing to Activity3 and then coming back to Activity 2 the progressbar is resetting and starting all over from zero.
I would like the progressbar to update continuously for the set time without interruptions. I tried using the services but the result is still the same.
I hope the code below helps in idenfying the issue and would really appreciate if anyone helps me out.

I have two activities: MainActivity and ActivityTwo. When starting application, I start service serviceApp, which after some events should start ActivityTwo. For the test, I made the launch after 10 seconds and AsyncTask, but if the application is hidden, activity does not start
How do I launch activity even if the app is hidden?

I found an easy way to fix this ailment, you need to give the application the SYSTEM_ALERT_WINDOW permission
https://developer.android.com/guide/components/activities/background-starts
AndroidManifest.xml
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />

Intent myIntent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION);
startActivity(myIntent);
Below is the code for my music player. I use Videoview to play a local list of selective songs.
I want to store and resume the playback position when orientation changes (portrait/landscape).
I have used onSaveInstanceState and onRestoreInstanceState methods. No errors on build, but still the songs reset every time.
I couldn't figure out what's wrong.
package io.automaton.android.morningbinge;
import androidx.appcompat.app.AlertDialog;
import android.app.Activity;
import android.content.DialogInterface;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.widget.Toast;
import android.widget.VideoView;
import android.widget.MediaController;
import java.util.ArrayList;
public class MainActivity extends Activity
implements MediaPlayer.OnCompletionListener {
VideoView vw;
ArrayList<Integer> videolist = new ArrayList<>();
int currvideo = 0;
int mPositionWhenPaused=0;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
vw = (VideoView)findViewById(R.id.videoView);
vw.setMediaController(new MediaController(this));
vw.setOnCompletionListener(this);
// video name should be in lower case alphabet.
videolist.add(R.raw.onbadhu_kolum);
videolist.add(R.raw.kala_bhairava_ashtakam);
videolist.add(R.raw.panchamukh_hanumath_kavacham);
videolist.add(R.raw.kandha_shashti_kavasam);
setVideo(videolist.get(0));
}
#Override
public void onSaveInstanceState(Bundle savedInstanceState) {
super.onSaveInstanceState(savedInstanceState);
//we use onSaveInstanceState in order to store the video playback position for orientation change
savedInstanceState.putInt("Position", vw.getCurrentPosition());
vw.pause();
}
#Override
public void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
//we use onRestoreInstanceState in order to play the video playback from the stored position
mPositionWhenPaused = savedInstanceState.getInt("Position");
vw.seekTo(mPositionWhenPaused);
}
public void setVideo(int id)
{
String uriPath
= "android.resource://"
+ getPackageName() + "/" + id;
Uri uri = Uri.parse(uriPath);
vw.setVideoURI(uri);
vw.start();
}
public void onCompletion(MediaPlayer mediapalyer)
{
AlertDialog.Builder obj = new AlertDialog.Builder(this);
obj.setTitle("Playback Finished!");
obj.setIcon(R.mipmap.ic_launcher);
MyListener m = new MyListener();
obj.setPositiveButton("Replay", m);
obj.setNegativeButton("Next", m);
obj.setMessage("Want to replay or play next video?");
obj.show();
}
class MyListener implements DialogInterface.OnClickListener {
public void onClick(DialogInterface dialog, int which)
{
if (which == -1) {
vw.seekTo(0);
vw.start();
}
else {
++currvideo;
if (currvideo == videolist.size())
currvideo = 0;
setVideo(videolist.get(currvideo));
}
}
}
}
I sorted out the issue. I changed the way the list is being called to play with the setOnPreparedListener, seeking to last played position.

.setSound(sound)
.build();
nNM.notify(1,mNotify);
}
}
And here's my manifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<application
android:allowBackup="true"
android:icon="#mipmap/logo"
android:label="#string/app_name"
android:theme="#style/MyTheme">
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".Main2Activity"
android:label="#string/title_activity_main2">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity android:name=".Main3Activity" />
<activity android:name=".Main4Activity"></activity>
</application>
You have to register NotifyService1 and NotifyService2 in AndroidManifest.xml.
I am having a little trouble with my android development project. I have created an application which allows the user to insert/read/update and delete records from a MySQL database. This is using JSON. The application keeps crashing with a fatal exception main? Not too sure what it is as none of the pages created are showing any errors. I also have used php to connect to the database and query it. There are 5 java files and 4 xml layout files. Not sure if you would like me to put them all on here as it might get to be too much so for now I will add them in my public folder of dropbox, if I need to put all of the pages here I will edit the question. https://www.dropbox.com/s/iakgmx7aci78b65/AndroidAssignment.zip?dl=0
UPDATE:
I managed to get rid of most errors but its sending a error saying unable to find explicit activity class ViewAllEmployee for the onClick method;
Process: com.example.assignment.androidassignment, PID: 2211 android.content.ActivityNotFoundException: Unable to find explicit activity class {com.example.assignment.androidassignment/com.example.assignment.androidassignment.ViewAllEmployee}; have you declared this activity in your AndroidManifest.xml?

You need to add the activity ViewAllEmployee to your manifest between the Application tags
<application ...>
<activity
android:name=".ViewAllEmployee" />
</application>
