How to set the Audio Mode in Android to improve call Quality?

Problem:
I have a that i regularly talk to via Discord but the Audio Quality is quite bad except when she is being called (ringtone) or sometimes when playing back videos on Instagram. My theory is that the Audio Mode android uses internally affects sound quality (MODE_IN_CALL -> bad, MODE_RINGTONE -> good).
Attempted solution:
Write an app in android studio that emulates all the possible audio modes using AudioManager.
Problem 2:
I know very little about java and android and stuff (i mostly program c++ for arduinos) and i can't get it to work.
I hope im not asking too much here. This is my **horrible **attempt:
package cf.hacker3000.audiomodeswitcher;

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ring = (Button) findViewById(R.id.btn_ring);
alarm = (Button) findViewById(R.id.btn_alarm);

Keep app running in background on Android

I am really new to Android Programming. I am working on a simple app: FlashLight for Android.
I need the app to continue run in background if the user presses the menubutton or locks the screen. The light should not stop until the user presses the button the stop the light.
Below is my code:
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.pm.PackageManager;
import android.hardware.Camera;
import android.hardware.Camera.Parameters;
import android.media.MediaPlayer;

import android.view.View;
import android.widget.ImageButton;
public class MainActivity
extends Activity {
ImageButton btnSwitch;
private Camera camera;
private boolean isFlashOn;
private boolean hasFlash;
Parameters params;
MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// flash switch button
btnSwitch = (ImageButton) findViewById(R.id.btnSwitch);
// First check if device is supporting flashlight or not
hasFlash = getApplicationContext().getPackageManager().hasSystemFeature(PackageManager.FEATURE_CAMERA_FLASH);
if(!hasFlash) {
// device doesn't support flash
// Show alert message and close the application
AlertDialog alert = new AlertDialog.Builder(MainActivity.this).create();
alert.setTitle("Error");
alert.setMessage("Sorry, your device doesn't support flash light!");
alert.setButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// closing the application
finish();
}
});
alert.show();
return;
}
// get the camera
getCamera();
// displaying button image
toggleButtonImage();
// Switch button click event to toggle flash on/off
btnSwitch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(isFlashOn) {
// turn off flash
turnOffFlash();
} else {
// turn on flash
turnOnFlash();
}
}
});
}
// Get the camera

if(camera == null) {
try {

params = camera.getParameters();
} catch(RuntimeException e) {
Log.e("Camera Error. Failed to Open. Error: ", e.getMessage());
}
}
}
// Turning On flash
private void turnOnFlash() {
if(!isFlashOn) {
if(camera == null || params == null) {
return;
}
params = camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_TORCH);
camera.setParameters(params);
camera.startPreview();
isFlashOn = true;
// changing button/switch image
toggleButtonImage();
}
}
// Turning Off flash
private void turnOffFlash() {
if(isFlashOn) {
if(camera == null || params == null) {
return;
}
params = camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_OFF);
camera.setParameters(params);
camera.stopPreview();
isFlashOn = false;
// changing button/switch image
toggleButtonImage();
}
}
/*

* changing image states to on / off
* */
private void toggleButtonImage() {
if(isFlashOn) {
btnSwitch.setImageResource(R.drawable.btn_switch_on);
} else {
btnSwitch.setImageResource(R.drawable.btn_switch_off);
}
}
/*
* Playing sound
* will play button toggle sound on flash on / off
* */
private void playSound() {
if(isFlashOn) {
mp = MediaPlayer.create(MainActivity.this, R.raw.light_switch_off);
} else {
mp = MediaPlayer.create(MainActivity.this, R.raw.light_switch_on);
}
mp.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
// TODO Auto-generated method stub
mp.release();
}
});
mp.start();
}
#Override
protected void onDestroy() {
super.onDestroy();
}
#Override
protected void onPause() {
super.onPause();
// on pause turn off the flash
turnOffFlash();
}
#Override
protected void onRestart() {
super.onRestart();
}
#Override
protected void onResume() {
super.onResume();
// on resume turn on the flash
if(hasFlash) {
turnOnFlash();
}
}
#Override
protected void onStart() {
super.onStart();
// on starting the app get the camera params
getCamera();
}
#Override
protected void onStop() {
super.onStop();
// on stop release the camera
if(camera != null) {
camera.release();
camera = null;
}
}
}

You;re turning off the light in onPause. When the screen is locked or the app is minimized, onPause is called. If you don't want that to happen, don't call it there.

I think you are searching for Services: http://developer.android.com/guide/components/services.html
They are very similar to an Activity but do dot provide a user interface and can run in the background.

Android: playing large video MP4 files through http

I have 300 MB videos on my http server...I'm trying to make good simple code to play (in 3G mode) these videos remotely in my application - sd storing or local storing is not a option. Of course I started from demo source in SDK android-17 (MediaPlayerDemo_Video, VideoViewDemo...) and in 3G mode my video doesn't play (I'm testing on Samsung Galaxy Nexus). After that I made new try in next code:

After that I played with 50 other tests with MediaPlayer and VIewVideo... All results are same - slow and freezed video playing. My need is pretty simple - I have big video files (mp4) on my website and I want to play them on my app. So I'm here - what is the right formula for playing of large remote files in android application?
PS: Of course I tried to use GStreamer but this framework is not compatible with last android environment - I played with in 2 days...My video is OK - in wifi mode I play http://snimkitevi-bg.com/darik/1.MP4
So could you give me some good advases, examples, tutorials how MediaPlayer could play normally, buffered and fastly big video files in 3G internet connection?

Splash Screen - Touch to Skip

I have the following code:
package com.example.top_tech_deals;
import android.app.Activity;
import android.content.Intent;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.view.MotionEvent;
import android.widget.VideoView;
public class Splash extends Activity{
#Override
protected void onCreate(Bundle TravisLoveBacon) {
// TODO Auto-generated method stub
super.onCreate(TravisLoveBacon);
setContentView(R.layout.splash);
VideoView vv = (VideoView)this.findViewById(R.id.videoView);
String fileName = "android.resource://" + getPackageName() + "/" + R.raw.splashvid2;
vv.setVideoURI(Uri.parse(fileName));
vv.start();
Thread timer = new Thread(){
public void run(){
try{
sleep(12000);
} catch(InterruptedException e){
e.printStackTrace();
} finally{
Intent openStartingPoint = new Intent ("android.intent.action.MENU");
startActivity(openStartingPoint);
}
}
};
timer.start();
}
//Function that will handle the touch
#Override
public boolean onTouchEvent(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
synchronized(timer){
splashTread.notifyAll();
}
}
return true;
}
}
By using one of Bucky's tutorials I managed to create the above code which is used to create a splash screen for 12 seconds. I also modified it so that a Video will play. The main problem I'm having is with the last bit of the code which is the OnTouchEvent I found online. What it should do is allow the user to skip the splash screen simply by tapping the screen, which should take the user to the MENU file.
The error seems to be in this line:
synchronized(timer){
Which says "error timer cannot be resolved into a variable"
Why is this happening and how can I fix it? Thanks for the help.

See code:
package com.example.top_tech_deals;
import android.app.Activity;
import android.content.Intent;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.view.MotionEvent;
import android.widget.VideoView;
public class Splash extends Activity{
Thread timer;
#Override
protected void onCreate(Bundle TravisLoveBacon) {
// TODO Auto-generated method stub
super.onCreate(TravisLoveBacon);
setContentView(R.layout.splash);
VideoView vv = (VideoView)this.findViewById(R.id.videoView);
String fileName = "android.resource://" + getPackageName() + "/" + R.raw.splashvid2;
vv.setVideoURI(Uri.parse(fileName));
vv.start();
timer = new Thread(){
public void run(){
try{
synchronized (this) {
wait(12000);
}
} catch(InterruptedException e){
e.printStackTrace();
} finally{
Intent openStartingPoint = new Intent ("android.intent.action.MENU");
startActivity(openStartingPoint);
}
}
};
timer.start();
}
//Function that will handle the touch
#Override
public boolean onTouchEvent(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
synchronized(timer){
timer.notify();
}
}
return true;
}
}

Your timer variable is local to your onCreate() method, but you're trying to access it (via synchronized) in a different method -- so it is unresolved. You need to either move timer to being a class data member, or use some other object whose scope is available in your onTouchEvent() method.

User a count downTimer instead of using a thread and in the override method onFinish()
CountDownTimer countDownTimer = new CountDownTimer(12000, 1000) {
public void onTick(long millisUntilFinished) {
//ToDO
}
public void onFinish() {
Intent openStartingPoint = new Intent ("android.intent.action.MENU");
startActivity(openStartingPoint);
}
}.start();
and in onTouch()
#Override
public boolean onTouchEvent(MotionEvent event) {
startActivity(openStartingPoint);
countDownTimer.cancle();
return true;
}

It seems your timer variable is not declare at class scope,it is declared in onCreate() function thats why other methods are not able to get it by reference. I suggest declare this as class variable like this private Thread timer = null; and initialize it in oncreate() method
#Override
protected void onCreate(Bundle TravisLoveBacon) {
// TODO Auto-generated method stub
super.onCreate(TravisLoveBacon);
setContentView(R.layout.splash);
VideoView vv = (VideoView)this.findViewById(R.id.videoView);
String fileName = "android.resource://" + getPackageName() + "/" + R.raw.splashvid2;
vv.setVideoURI(Uri.parse(fileName));
vv.start();
this.timer = new Thread(){
public void run(){
try{
sleep(12000);
} catch(InterruptedException e){
e.printStackTrace();
} finally{
Intent openStartingPoint = new Intent ("android.intent.action.MENU");
startActivity(openStartingPoint);
}
}
};
timer.start();
}

thread, MediaPlayer, ProgressDialog and context issues

I've tried and done everything that I read on internet and here on stackoverflow to solve my problem, but no success till now. What I'm trying to do is basically click on a button and show a ProgressDialog while the MediaPlayer is buffering a stream from internet. I got many types of erros with context stuff (NullPointerException) and thread problems too. Here are some details about the code:
the button is a toggle button with background image sat based on events (on, off, not connected show different image buttons);
The function prepareStream() is the one that should be ran in a thread and dismiss the ProgressDialog after load the stream. it's calling an http stream of BBC radio;
I guess that the problem is about the context... I've put some Log.d TAGs on the code to check where was happening the problem and O figured out that was on mediaPlayer.start() method.

So logcat tell me on the time mediaPlayer.start() is called the NullPointerException

You must run your ProgressDialog.show() in the runOnUiThread() method(Not in the main UI thread). See the Android docs here
Create a progress dialog object and then, write this code.
runOnUiThread(new Runnable(){
#Override
public void run() {
dialog.show();
}
});
Also the calls prepareStream() and mediaplayer.start() should go into a separate thread and not the main UI thread.
Sort out the thread related issues and you should be done.
