Youtube API crashes when I am in onpause state.
When I am playing Youtube video onclick it is working fine but when I am minimizing my app in onpause state it crashes. So give me some suggestions. I never used Youtube API before so I have no idea about it. Please review my code whether it is good. if not, then please provide good
suggestion too. Thanks in advance.

{
super.onPause();
if (youTubePlayer1 != null) {
if(youTubePlayer1.isPlaying()) {
// currentPlayerTime = youTubePlayer1.getCurrentTimeMillis();
youTubePlayer1.pause();
}
}
}
}
#Override
public void onPause()
{
super.onPause();
if (youTubePlayer1 != null) {
youTubePlayer1.release();
}
}
and you can save your current video time in savedInstanceState
but for better solution i will recommend you to initialize your player in onResume and release it in onStop like this.
#Override
protected void onResume() {
super.onResume();
playerView.initialize(KEY, this);
}
#Override
public void onStop() {
if (player != null) {
player.release();
}
player = null;
super.onStop();
}

I'm beginner in android development and tried to create a simple mediaplayer app which plays media from local source.
But it's crashing when i try to open it.
This is my java code.
package com.example.media;
import androidx.appcompat.app.AppCompatActivity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.SeekBar;
public class MainActivity extends AppCompatActivity {
Button play,pause;
SeekBar s;
MediaPlayer m;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
m=MediaPlayer.create(this,R.raw.live);
play=findViewById(R.id.button3);
pause=findViewById(R.id.button4);
s.findViewById(R.id.seekBar);
s.setMax(m.getDuration());
s.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
if(fromUser)m.seekTo(progress);
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
play.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
m.start();
}
});
pause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
m.pause();
}
});
}
}
You need to initialize the seekbar object instead of calling the findViewById method.
So just replace the dot with equal sign :
s=findViewById(R.id.seekBar);
I got to put the map in my app and running in my mobile, but I don't get to put the overlay file GeoJson from Assets Folder in the my locate folder in PC. I want to overlay the points from GeoJson and show popups of points' id. How could I do this?

The "stop" and "play" work fine, but "pause" works like "stop". When I press pause, the audiofile stops playing and when I press play, it starts from the beginning.

public class AudioPlayer {
private MediaPlayer mPlayer;
public void stop()
{
if(mPlayer != null)
{
mPlayer.release();
mPlayer = null;
}
}
public void pause()
{
if(mPlayer.isPlaying())

}
public void play(Context c)
{
stop();
mPlayer = MediaPlayer.create(c, R.raw.one_small_step);
mPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener()
{
#Override
public void onCompletion(MediaPlayer mp)
{
stop();
}
});
mPlayer.start();
}
}
it starts from the beginning because here:
public void play(Context c) {
stop();
mPlayer = MediaPlayer.create(c, R.raw.one_small_step);
you are releasing the old one a create it again
Try remembering the the player is paused:
public class AudioPlayer {
boolean isPaused = false;
public void pause() {
if(mPlayer.isPlaying()) {
mPlayer.pause();
isPaused = true;
}
}
public void play(Context c) {
if (isPaused && mPlayer != null) {
mPlayer.start();
isPaused = false
return;
}
stop();
mPlayer = MediaPlayer.create(c, R.raw.one_small_step);
Problem: When I use the home button to close the app the music continues playing. So I manually close the app by killing the activity, the music stops... for a few seconds and then starts again (and this time a restart is in order to turn it off).

(NOTE: I have taken excerpts from my app, so I may have forgotten imports in this code, but all imports are correctly included in the app.)
Fixed:

setContentView(R.layout.activity_main_page);
doBindService();
Intent music = new Intent();
music.setClass(this, MusicService.class);
startService(music);
}
and
#Override
protected void onDestroy() {
super.onDestroy();
doUnbindService();
}
please red : onCreate, OnPause , OnResume
I'm creating application to add movie data via external web service to internal database and display list of movies as the main activity in ListFragment, another activity is responsible for search function.
ListFragment mentioned above fetches data from database using LoaderManager. Also this fragment is retained using setRetainInstance(true).
Problem that I encounter is that when I navigate to search, add something to database, and go back to ListFragment by pressing Back Button its not refreshed i.e. added movie is not displayed.
A few important things:
I'm not using ContentProvider so I manually retrieve Cursor from my data base in onCreateLoaderMethod.
I'm using support library - I hope that all imports are proper (if someone could check).
ListFragment uses custom CursorAdapter as its view.
Here is the code:
package com.mp.movieplanner;
import android.app.Activity;
import android.database.Cursor;
import android.os.Build;
import android.os.Bundle;
import android.support.v4.app.ListFragment;
import android.support.v4.app.LoaderManager;
import android.support.v4.content.CursorLoader;
import android.support.v4.content.Loader;
import android.util.Log;
import android.view.View;
import android.widget.ListView;
import com.mp.movieplanner.data.DataManager;
public class MovieListFragment extends ListFragment
implements LoaderManager.LoaderCallbacks<Cursor> {
public static String TAG = MovieListFragment.class.getSimpleName();
private OnMovieSelectedListener mCallback;
private DataManager mDataManager;
private MovieCursorAdapter mAdapter;
public interface OnMovieSelectedListener {
public void onMovieSelected(int position);
}
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
Log.i(TAG, "onAttach(Activity)");
mDataManager = ((MoviePlannerApp)activity.getApplication()).getDataManager();
try {
mCallback = (OnMovieSelectedListener) activity;
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString()
+ " must implement OnMovieSelectedListener");
}
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.i(TAG, "onCreate(Bundle)");
final int layout = Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB ? android.R.layout.simple_list_item_activated_1
: android.R.layout.simple_list_item_1;
setRetainInstance(true);
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
Log.i(TAG, "onActivityCreated(Bundle)");
super.onActivityCreated(savedInstanceState);
mAdapter = new MovieCursorAdapter(getActivity(), null, 0);
setListAdapter(mAdapter);
getLoaderManager().initLoader(0, null, this);
}
#Override
public void onStart() {
super.onStart();
Log.i(TAG, "onStart()");
if (getFragmentManager().findFragmentById(R.id.movie_details_fragment) != null) {
getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);
}
}
#Override
public void onResume() {
super.onResume();
Log.i(TAG, "onResume()");
}
#Override
public void onDetach() {
super.onDetach();
Log.i(TAG, "onDetach()");
mCallback = null;
}
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
// Notify the parent activity of selected item
if (mCallback != null) {
mCallback.onMovieSelected(position);
// Set the item as checked to be highlighted when in two-pane layout
getListView().setItemChecked(position, true);
}
}
#Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
return new CursorLoader(getActivity()) {
#Override
public Cursor loadInBackground() {
return mDataManager.getMovieCursor();
}
};
}
#Override
public void onLoadFinished(Loader<Cursor> loader, Cursor data) {
mAdapter.swapCursor(data);
}
#Override
public void onLoaderReset(Loader<Cursor> arg0) {
mAdapter.swapCursor(null);
}
#Override
public void onPause() {
Log.i(TAG, "onPause()");
super.onPause();
}
#Override
public void onStop() {
Log.i(TAG, "onStop()");
super.onStop();
}
#Override
public void onDestroy() {
super.onDestroy();
Log.i(TAG, "onDestroy()");
}
}
I would advise:
#Override
public void onResume() {
super.onResume();
Log.i(TAG, "onResume()");
getLoaderManager().restartLoader(0, null, this);
}
#Override
public void onResume() {
super.onResume();
Log.i(TAG, "onResume()");
getLoaderManager().initLoader(0, null, this);
}
try that
