I want to do appear an Insterstitial ad WHEN flash is OFF

i have this code, and i want to do appear an insterstitial ad when the flash is off (my app is a flashlight) But when i try to do it i get an error.
All what i do is to put the onReceiveAd code where i want it.
I put the code here:
// 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(); <---- FLASH GO OFF
#Override
public void onReceiveAd(Ad ad) { <------ Insterstitial AD should APPEAR
Log.d("OK", "Received ad");
if (ad == interstitial) {
interstitial.show();
}
}
} else{
etc etc...
But i get this error:
Multiple markers at this line
- Syntax error on token "(", ;
expected
- Syntax error on token ")", ;
expected
How can i do to do it works?
private InterstitialAd interstitial;
#Override

How to close activity without destroying it?

Ok so first, I have menu with 3 buttons leading to 3 different layouts.
What I want, I want to show interstitial ad when I close my application.
What happens, In order to save memory I had to add finish() on every button so it doesn't take all memory. And when I click on any button interstitial ad shows.
Whats the problem, I can't set my code to show interstitial only when I completely close app not when I switch activities
My code:
package puske.com;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import com.google.ads.*;
import com.google.ads.AdRequest.ErrorCode;
public class Menu extends Activity implements AdListener {
private InterstitialAd interstitial;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.menu);
interstitial = new InterstitialAd(this, "ID");
// Create ad request
AdRequest adRequest = new AdRequest();
// Begin loading your interstitial
interstitial.loadAd(adRequest);
// Set Ad Listener to use the callbacks below
interstitial.setAdListener(this);
}
#Override
public void onReceiveAd(Ad ad) {
{
Button button1=(Button)findViewById(R.id.menu1);
button1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
startActivity(new Intent(Menu.this, Rifles.class));
finish();
}
});
Button button2=(Button)findViewById(R.id.menu2);
button2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
startActivity(new Intent(Menu.this, Pistols.class));
finish();
}
});
Button button4=(Button)findViewById(R.id.menu3);
button4.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
startActivity(new Intent(Menu.this, Snipers.class));
finish();
}
});
}
}
#Override
protected void onDestroy() {
interstitial.show();
super.onDestroy();
// explicitly release media player
unbindDrawables(findViewById(R.id.menuzor));
System.gc();
}
private void unbindDrawables(View view) {
if (view.getBackground() != null) {
view.getBackground().setCallback(null);
}
if (view instanceof ViewGroup) {
for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {
unbindDrawables(((ViewGroup) view).getChildAt(i));
}
try
{
((ViewGroup) view).removeAllViews();
}
catch(UnsupportedOperationException ignore)
{
}
}
}
#Override
public void onLeaveApplication(Ad arg0) {
// TODO Auto-generated method stub

How can i do, to run a SIMPLE app (like this, its a simple flashlight) in ALL or almost all devices?
Thanks and sorry for my english

your issue is in getCamera(), in the line Log.e("Camera Error. Failed to Open. Error: ", e.getMessage());
it looks like e.getMessage() is returning null, hence the crash.
you should probably use the format Log.e(TAG, "getCamera", e); which will print the stack trace for the exception (and not crash your app)

Replace
Log.e("Camera Error. Failed to Open. Error: ", e.getMessage());
with
Log.e("MainActivity", "Camera Error. Failed to Open. Error: " + e.getMessage());
then figure out why the camera doesn't work.

Android MedialPlayer, where to release and create?

I am trying to play a sound when button is pressed. To do so, I tried few methods :
1 : Created a MediaPlayer under and played it when button is pressed like this :
MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mp = MediaPlayer.create(MainActivity.this, R.raw.bell);
mp.setLooping(false);
Button b = (Button) findViewById(R.id.button1);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
mp.seekTo(0);
mp.start();
}
});
}
This method worked like charm. But then I wanted to conserve memory and wanted to release MediaPlayer when activity is in background. So I added this
#Override
protected void onPause() {
// TODO Auto-generated method stub
mp.release();
super.onPause();
}
But now, when activity comes back in foreground it throws an error ( because MediaPlayer is created under OnCreate).
So, I thought to create it under onResume since it is always called.
#Override
protected void onResume() {
// TODO Auto-generated method stub
mp = MediaPlayer.create(MainActivity.this, R.raw.bell);
mp.setLooping(false);
super.onResume();
}
It worked.
Full code is like this :
package com.example.learn;
import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity implements OnClickListener {
MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button b = (Button) findViewById(R.id.button1);
b.setOnClickListener(this);
}
#Override
protected void onPause() {
// TODO Auto-generated method stub
mp.release();
super.onPause();
}
#Override
protected void onResume() {
// TODO Auto-generated method stub
mp = MediaPlayer.create(MainActivity.this, R.raw.bell);
mp.setLooping(false);
super.onResume();
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.button1: {
mp.seekTo(0);
mp.start();
}
}
}
}
just thinking have I done it right? Are there better and easier ways?

By looking on your code I think you have done it in a right way. You can Create that in onResume as it is always called. On Create is Called for the first time only.
And Yes ALWAYS call
mediaPlayer.relaese();
instead of
mediaPlayer.stop();
Everything in your code is looking right. For more accuracy you can have a glance on this

Why SurfaceView doesn't display 3gp video in Android

I am using the following sample code to play a 3gp video. on android 2.3 .. but only the audio is playing, but the video doesn't appear . what is the problem ?
package pit.opensource.video;
import android.app.Activity;
import android.content.Context;
import android.graphics.PixelFormat;
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
import android.view.View;
import android.widget.Button;
import android.widget.SeekBar;
public class L2VideoExampleActivity extends Activity implements SurfaceHolder.Callback{
MediaPlayer mediaPlayer;
SurfaceView surfaceView;
SurfaceHolder surfaceHolder;
boolean pausing = false;
AudioManager audioManager;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
audioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
int maxVolume = audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
int curVolume = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
SeekBar volControl = (SeekBar)findViewById(R.id.volbar);
volControl.setMax(maxVolume);
volControl.setProgress(curVolume);
volControl.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onStopTrackingTouch(SeekBar arg0) {
// TODO Auto-generated method stub
}
#Override
public void onStartTrackingTouch(SeekBar arg0) {
// TODO Auto-generated method stub
}
#Override
public void onProgressChanged(SeekBar arg0, int arg1, boolean arg2) {
// TODO Auto-generated method stub
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, arg1, 0);
}
});
Button buttonPlayVideo = (Button)findViewById(R.id.playvideoplayer);
Button buttonPauseVideo = (Button)findViewById(R.id.pausevideoplayer);
getWindow().setFormat(PixelFormat.UNKNOWN);
surfaceView = (SurfaceView)findViewById(R.id.surfaceview);
surfaceHolder = surfaceView.getHolder();
surfaceHolder.addCallback(this);
surfaceHolder.setFixedSize(176, 144);
surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
mediaPlayer = new MediaPlayer();
buttonPlayVideo.setOnClickListener(new Button.OnClickListener(){
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
pausing = false;
if(mediaPlayer.isPlaying()){
mediaPlayer.reset();
}
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setDisplay(surfaceHolder);
try {
// mediaPlayer.setDataSource(stringPath);
// mediaPlayer.prepare();
mediaPlayer = MediaPlayer.create(getApplicationContext(), R.raw.samplevideo);
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mediaPlayer.start();
}});
buttonPauseVideo.setOnClickListener(new Button.OnClickListener(){
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(pausing){
pausing = false;
mediaPlayer.start();
}
else{
pausing = true;
mediaPlayer.pause();
}
}});
}
#Override
public void surfaceChanged(SurfaceHolder holder, int format, int width,
int height) {
// TODO Auto-generated method stub
}
#Override
public void surfaceCreated(SurfaceHolder holder) {
// TODO Auto-generated method stub
}
#Override
public void surfaceDestroyed(SurfaceHolder holder) {
// TODO Auto-generated method stub
}
}

I think you must play video in surfaceview.you now play video in oncreate and may be surfaceview not created yet.
use something like this in surfaceCreated
#Override
public void surfaceCreated(SurfaceHolder holder)
{
if(ArrayManager.array_for_playing != null)
if(SDcard.icurrentIndex != -1)
playVideo(SDcard.icurrentIndex);
}
and this is playVideo method
private void playVideo(Integer Media)
{
try {
mPlayer.reset();
mPlayer.setDataSource(ArrayManager.array_for_playing.get(SDcard.icurrentIndex).getPath());
mPlayer.setDisplay(holder);
songProgressBar.setProgress(0);
songProgressBar.setMax(100);
mPlayer.prepare();
mPlayer.start();
btnPlay.setBackgroundResource(R.drawable.img_btn_pause);
// Updating progress bar
updateProgressBar();
}
catch (Exception e)
{
Log.e("video player", "error: " + e.getMessage(), e);
}
}
And in IniatializeUi method
private void InitializeUI()
{
mPreview = (SurfaceView) findViewById(R.id.surface_view);
holder = mPreview.getHolder();
holder.addCallback(this);
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
}
and in top of activity :
private SurfaceView mPreview;
private SurfaceHolder holder;
I hope this help users.
