You have to stop the MediaPlayer before switching to another activity. You may use the OnActivityResult result for stopping Mediaplayer while switching between activities.
Here is the sample code:
public static final int REQUEST_CODE = 1;
Intent in = new Intent(QuizActivity.this, MainActivity.class);
startActivityForResult(in, REQUEST_CODE);
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
try {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_CODE && resultCode == RESULT_OK) {
mMediaPlayer.stop()
}
} catch (Exception ex) {
}
}
Also, make sure that you cancel the CountDownTimer before switching to another activity.
I created an application which pairs a cellphone to a bluetooth module.
i tested this application with a 4.2 android cellphone and it worked quite well but in cellphones with android higher than 6 the device is not fidning anything when i press " Scan for new devices " button.
but when i go through my phone bluetooth itself, i can find the module i was looking for..

in an article i studied about this issue and find out that with this code :
if (ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_COARSE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(context,
new String[]{Manifest.permission.ACCESS_COARSE_LOCATION},
1);
i can make the application to support phones with android more than 6 so i can discover all nearby devices and pair with them,
The issue is, i don't know where should i exactly use this code..
i would really appreciate if you could tell me where to use it within the codes i showed here.
or simply tell me how to overcome this problem with any other code you may know.
In your AndroidManifest.xml file add this:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
Then, instead of calling registerReceiver call this function:
private tryRegisterReceiver() {
if (ContextCompat.checkSelfPermission(thisActivity,
Manifest.permission.ACCESS_COARSE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
// Here, permission is not granted
// after calling requestPermissions, the result must be treated in onRequestPermissionResult
ActivityCompat.requestPermissions(thisActivity,
new String[]{Manifest.permission.ACCESS_COARSE_LOCATION},
1000); // 100 or other desired code
} else {
// Permission has already been granted
// continue registering your receiver
registerReceiver();
}
}
To treat the result of the permission request
#Override
public void onRequestPermissionsResult(int requestCode,
String[] permissions, int[] grantResults) {
switch (requestCode) {
case 1000: {
// If request is cancelled, the result arrays are empty.
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// permission was granted
// continue registering your receiver
registerReceiver();
} else {
// permission denied
// show a message or finish your activity
}
return;
}
// other 'case' for other permissions if needed
}
}
My Countdown timer is working fine but when I use back press during running state of the time, my countdown timer did not stop. I have tried everything as follows but none of them is able to stop the countdown timer from running in the background.

New Activity UI load but does not respond, After running onStop() which trigger submit()
List View with the checkbox is bound by a custom adapter. On touch of the Submit button, an intent is triggered which takes me to HomeActivity and onStop() method is triggered which in return call submit method. All submit method is created under a new thread which interfere with UI.

Setting up Google Speech cloud on Android is not a straightforward 1,2,3 process, but I will give you some guidance.
Download the Sample project from here, use the Speech example.
https://github.com/GoogleCloudPlatform/android-docs-samples/tree/master/speech/Speech
Setup a google cloud project, enable the Speech API, and link it to
your gmail account's billing (you get 60min of free speech recognition
every month).
Generate an authentication json, and put it into the "raw" folder of
the sample project.
Setup Google cloud on your computer and obtain an access token.
Insert that access token on your SpeechService.java class.
*Documentation on steps 3 and 4:
https://cloud.google.com/speech/docs/getting-started
*If you run into problems when trying to mimic the sample project into your own project, check this:
Cannot import com.google.cloud.speech.v1.SpeechGrpc in Android
The exact steps are too long to list, I can't even remember them all, if you run into specific trouble let me know.
