Apps NullPointerException in onCreate?

[eatfishy]

I am getting this error message on new android phone models, but it works fine on my Droid Phone using 2.2 OS. Does anyone know how to troubleshoot this error message?

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.simpoware.omgannoyingsounds/com.simpoware.omgannoyingsounds.TabBar}: java.lang.RuntimeException: Unable to start activity ComponentInfo{com.simpoware.omgannoyingsounds/com.simpoware.omgannoyingsounds.Main}: java.lang.NullPointerException

Below is my code:


/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

//greystripe
myBanner = (BannerView) findViewById(R.id.gsBanner);
myBanner.refresh();

//set audio player
player01 = MediaPlayer.create(this, R.raw.modem);
player02 = MediaPlayer.create(this, R.raw.high_pitch_dog_whistle);
player03 = MediaPlayer.create(this, R.raw.alarm_clock);
player04 = MediaPlayer.create(this, R.raw.faulty_mechanics_sound);

player10 = MediaPlayer.create(this, R.raw.hailstorm);
player11 = MediaPlayer.create(this, R.raw.electric_toothbrush);
player12 = MediaPlayer.create(this, R.raw.ecg);

player01.setLooping(true); // Set looping

// Get the ImageButton from XML
imgButton01 = (ImageButton) this.findViewById(R.id.ImageButton01);
imgButton02 = (ImageButton) this.findViewById(R.id.ImageButton02);
imgButton03 = (ImageButton) this.findViewById(R.id.ImageButton03);
imgButton04 = (ImageButton) this.findViewById(R.id.ImageButton04);
imgButton05 = (ImageButton) this.findViewById(R.id.ImageButton05);
imgButton06 = (ImageButton) this.findViewById(R.id.ImageButton06);
imgButton07 = (ImageButton) this.findViewById(R.id.ImageButton07);
imgButton08 = (ImageButton) this.findViewById(R.id.ImageButton08);
imgButton09 = (ImageButton) this.findViewById(R.id.ImageButton09);
imgButton10 = (ImageButton) this.findViewById(R.id.ImageButton10);
imgButton11 = (ImageButton) this.findViewById(R.id.ImageButton11);
imgButton12 = (ImageButton) this.findViewById(R.id.ImageButton12);

//Set click listener
imgButton01.setOnClickListener(this);
imgButton02.setOnClickListener(this);
imgButton03.setOnClickListener(this);
imgButton04.setOnClickListener(this);
imgButton05.setOnClickListener(this);
imgButton06.setOnClickListener(this);
imgButton07.setOnClickListener(this);
imgButton08.setOnClickListener(this);
imgButton09.setOnClickListener(this);
imgButton10.setOnClickListener(this);
imgButton11.setOnClickListener(this);
imgButton12.setOnClickListener(this);

}


Again, it works fine on my droid phone and ran smoothly on the emulator. Many users tried to download my app and it doesn't work for their android phones, which are droid2, droidx, milestone, any new model..
