I've developed a news android app, this app uses a MediaPlayer class to stream newscast tracks from SoundCloud and everything works fine. Now let's say the user pressed the play button from inside the app and the music starts playing. Now the user pressed the hardware home button and the app went to the background or the user pressed the sleep button to turn off the screen. I have managed to let the music playing in the background but i want the user to be able to control the MediaPlayer from outside the app (pause, stop, next, prev actions).
I searched a lot and didn't find anything, How can i do that?
I didn't put my code because i think it's irrelevant Please tell me if you want to see the code.
Thanks in advance.
I've done something similar by adding a custom notification with images/buttons to control the audio play and channel from the Android notification bar.
I think this is what you are after.
Notification code:
public Notification buildNotification()
{
Intent intent = new Intent(mContext, MainActivity.class);
PendingIntent pIntent = PendingIntent.getActivity(mContext, 0, intent, 0);
setContentView();
Notification.Builder notibuilder = new Notification.Builder(mContext);
notibuilder.setContentTitle(" ");
notibuilder.setContentText(" ");
notibuilder.setSmallIcon(R.drawable.ic_launcher);
notibuilder.setOngoing(true);
notibuilder.setAutoCancel(false);
notibuilder.setContentIntent(pIntent);
notibuilder.setContent(mContentView);
notibuilder.setTicker(null);
mNotification = notibuilder.build();
NotificationManager notificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
return mNotification;
}
public void setContentView()
{
mContentView = new RemoteViews(mContext.getPackageName(), R.layout.custom_notification);
mContentView.setTextViewText(R.id.notificaiton_app_title, "");
String currentChannel = " ";
if ( mCurrentChannel != -1)
currentChannel = " " + (mCurrentChannel + 1);
mContentView.setTextViewText(R.id.notificaiton_app_channel, currentChannel);
Intent previousIntent = new Intent(mContext, NotificationButtonIntentService.class);
previousIntent.setAction(NotificationButtonIntentService.Action_Previous);
mContentView.setOnClickPendingIntent(R.id.notification_layout_previous, PendingIntent.getService(mContext, 0, previousIntent, PendingIntent.FLAG_CANCEL_CURRENT));
mContentView.setOnClickPendingIntent(R.id.notification_image_previous, PendingIntent.getService(mContext, 0, previousIntent, PendingIntent.FLAG_CANCEL_CURRENT));
Intent playIntent = new Intent(mContext, NotificationButtonIntentService.class);
if ( mCurrentChannel != -1)
{
playIntent.setAction(NotificationButtonIntentService.Action_Pause);
mContentView.setInt(R.id.notification_image_play_pause, "setBackgroundResource", R.drawable.ic_media_pause);
}
else
{
playIntent.setAction(NotificationButtonIntentService.Action_Play);
mContentView.setInt(R.id.notification_image_play_pause, "setBackgroundResource", R.drawable.ic_media_play);
}
mContentView.setOnClickPendingIntent(R.id.notification_layout_play_pause, PendingIntent.getService(mContext, 0, playIntent, PendingIntent.FLAG_CANCEL_CURRENT));
mContentView.setOnClickPendingIntent(R.id.notification_image_play_pause, PendingIntent.getService(mContext, 0, playIntent, PendingIntent.FLAG_CANCEL_CURRENT));
Intent nextIntent = new Intent(mContext, NotificationButtonIntentService.class);
nextIntent.setAction(NotificationButtonIntentService.Action_Next);
mContentView.setOnClickPendingIntent(R.id.notification_layout_next, PendingIntent.getService(mContext, 0, nextIntent, PendingIntent.FLAG_CANCEL_CURRENT));
mContentView.setOnClickPendingIntent(R.id.notification_image_next, PendingIntent.getService(mContext, 0, nextIntent, PendingIntent.FLAG_CANCEL_CURRENT));
Intent closeIntent = new Intent(mContext, NotificationButtonIntentService.class);
closeIntent.setAction(NotificationButtonIntentService.Action_Close);
mContentView.setOnClickPendingIntent(R.id.notification_layout_close, PendingIntent.getService(mContext, 0, closeIntent, PendingIntent.FLAG_CANCEL_CURRENT));
mContentView.setOnClickPendingIntent(R.id.notification_image_close, PendingIntent.getService(mContext, 0, closeIntent, PendingIntent.FLAG_CANCEL_CURRENT));

You need yo access your MediaPlayer object. make it static and create your static pause,start,etc methods. something like this:
public class myMediaPlayer{
static MediaPlayer mediaPlayer = null;
public static void start(final Context context, Uri media){
mediaPlayer = new MediaPlayer();
mediaPlayer.setDataSource(context, media);
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MEDIA);
mediaPlayer.prepare();
mediaPlayer.start();
}
public static void stop() {
if(mediaPlayer!=null)
mediaPlayer.release();
}

You can not use applicationcontext in here, but if you want you need to add flags to the intent. So easier method for you to use "this" instead:
mCreateRem.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(this, FoodAddReminder.class);
startActivity(intent);
//Starts the new activity to add Reminders
}
});
We can only "guess" why, but "not working" and "app keeps stopping" could mean a lot of things and you didn't provide any Log information or an Exception stacktrace. Its also hard to guess what FoodAddReminder.class is, if its an activity, make sure its declared in your AndroidManifest.xml
mCreateRem.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(this, FoodAddReminder.class); // <-- is this an activity?
startActivity(intent);
//Starts the new activity to add Reminders
}
});
Check your AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.me.my.project">
<application >
<activity
android:name=".FoodAddReminder"/> <!-- here -->
</application>
</manifest>
If that is not the issue, I suspect that using getApplicationContext(), you're having this crash log
AndroidRuntimeException: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this
really what you want?
You should then tell the system you want to start a new task,
public void onClick(View v) {
Intent intent = new Intent(getApplicationContext(), FoodAddReminder.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
But I would suggest not doing it, instead use your FoodActivity as your calling activity to FoodReminder in this case, and pay attention to this, it should be prefixed with FoodActivity otherwise it will refer to its enclosing anonymous OnClickListener instance.
#Override
public void onClick(View v) {
Intent intent = new Intent(FoodActivity.this, FoodAddReminder.class);
startActivity(intent);
}
If none of these solved your "not working" issue, please provide a more specific Log information and reduce your code to something that is copy-and-paste-able.
I have an App that verifies the ID card by clicking photos from both sides, after clicking the picture front-side of the id card the user moves to another activity for clicking the picture back-side of the id card after completing those prosses the user redirect to another activity that the user sees both sides of the document into different ImageView but I don't know how to fetch or pass
those images on this Activity that user can see their ID card for confirmation.

The root layout should be DrawerLayout, and you need to move the current ConstraintLayout within the DrawerLayout
The skeleton of the layout should be something like:
<?xml version="1.0" encoding="utf-8"?>
<androidx.drawerlayout.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Main screen layout -->
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
<!-- Drawer layout -->
<com.google.android.material.navigation.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/navigation_header_layout"
app:menu="#menu/navigation_menu" />
</androidx.drawerlayout.widget.DrawerLayout>
And you can build views on the main screen within the ConstraintLayout
I am setting a repeated alarm in the Android, which fires the activity.
This activity is having two buttons: "stop" and "snooze". When I click on "snooze" alarm is postponed to 10 minutes.
But the alarm is in slider window, i.e it is in onresume state.
I want to stop the alarm completely on both the buttons.
public class RingAlarm extends Activity {
MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ring_alarm);
Intent in;
in = getIntent();
String s=in.getStringExtra("habbit_id");
int col= in.getIntExtra("habbit_Color",0);
ScrollView sv = (ScrollView)findViewById(R.id.sv_ra);
if(col<0)
{
sv.setBackgroundResource(R.color.red);
}
if(col>0) {
sv.setBackgroundResource(R.color.green);
}
if(col==0)
{
sv.setBackgroundResource(R.color.yellow);
}
System.out.println("alarm string" + s);
TextView tv = (TextView)findViewById(R.id.habbit_ra);
tv.setText(s);
// mp = MediaPlayer.create(getApplicationContext(), R.raw.song1);
//mp.start();
}
public void onthecancelringclicked(View view){
//mp.stop();
int id=Process.myPid();
finish();
Process.killProcess(id);
//System.exit(0);
}
public void onthesnoozeringclicked(View view){
//mp.stop();
long l=System.currentTimeMillis();
Intent i = this.getIntent();
Random r = new Random();
int ri =r.nextInt(1000000)+64;
PendingIntent pi = PendingIntent.getActivity(this,ri,i,0 );
AlarmManager am = (AlarmManager)this.getSystemService(Context.ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP,l+600000,pi);
finish();
Process.killProcess(Process.myPid());
}
}
And my XML file is:

As you can see I have implemented Process.killProcess(pid) method. Still my alarm is getting saved into the navigation drawer. I want to remove the activity from everywhere.
i am using same intent for 32 alarms so i can not put the id of the pending intent to the intent as putExtra.
Hopefully this will give you an idea of how to cancel/stop the alarm:
Intent intent = new Intent(context, MyClass.class);
PendingIntent recurring = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager alarms = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
if(active) { //If alarm is active
alarms.cancel(recurring);
recurring.cancel();
} else {
// Do something..
}
I copied it from one of my projects and it works for me.
add the following lines in the entry of the activity that is fired in the menifest file.
android:excludeFromRecents="true"
this will not let the activity go into recents and calling finish will lead to end of the activity.
I am developing an application using sms, my requirement is 1) send sms with static values 2)whenever we click on edit button we can change values and send sms , I can do both of them successfully but my third requirement is to send sms only when click on edit and change values click on submit buttons, without change value I do not want send sms.

public class MainActivity extends Activity {
private EditText contactEdit;
private EditText messageEdit;
private Button submitBtn;
private Button editBtn;
String contact;
String message;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
contactEdit = (EditText)findViewById(R.id.numberEdit);
messageEdit = (EditText)findViewById(R.id.messageEdit);
submitBtn = (Button)findViewById(R.id.subBtn);
editBtn = (Button)findViewById(R.id.editBtn);
if(editBtn.isSelected()){
submitBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
contact = contactEdit.getText().toString();
message = messageEdit.getText().toString();
try{
SmsManager manger = SmsManager.getDefault();
manger.sendTextMessage(contact, null, message, null,
null);
Toast.makeText(getApplicationContext(), "SMS SENT",
100).show();
}
catch(Exception e){
Toast.makeText(getApplicationContext(), "SMS NOT
SEND", 100).show();
e.printStackTrace();
}
}
});
}
else {
Toast.makeText(getApplicationContext(), "NOT EDITED", 100).show();
}
editBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
changeEdit();
}
});
}
private void changeEdit(){
contactEdit.setClickable(true);

contactEdit.setFocusableInTouchMode(true);
messageEdit.setClickable(true);
messageEdit.setCursorVisible(true);
messageEdit.setFocusable(true);
messageEdit.setFocusableInTouchMode(true);
}
}
Try to use OnTouchListener for the edittext
sample,
editBtn.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
changeEdit();
return true;
}
});
if its not working
Create a boolean variable Globally and make it true if u touched onto the edittext,
//In grobal
boolean e_clicked = false;
//Inside the Edittext onTouchListener
e_clicked=true;
and check
if(e_clicked)
{
// your sms send action
}
try this
public class AlarmReceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
#Override
public void onReceive(Context context, Intent intent) {
Intent intent=new Intent(context,Service.class);
//get lat/lng and pass it or get from service if u want
intent.putExtra("lat","lat");
intent.putExtra("lon","lng");
context.startService(intent);
}
}
public void SetAlarm(Context context) {
AlarmManager am = (AlarmManager) context
.getSystemService(Context.ALARM_SERVICE);
Intent i = new Intent(context, AlarmReceiver.class);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.add(Calendar.MINUTE, 10);
am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(),
calendar.getTimeInMillis(), pi);
}
