Eu criei um programa no Android Studio que tem 10 botões de imagem, cada botão de imagem quando clicado produz um som. No entanto, quando eu os executo no emulador, apenas os 7 primeiros botões de imagem produzirão um som (não importa em que ordem o botão em que clicou). Sou novo nisso, me ajude, este é o meu código:

public class playtimang extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_playtimang);

    final MediaPlayer satukecik = MediaPlayer.create(this, R.raw.one_kecik);
    final MediaPlayer satubesar = MediaPlayer.create(this, R.raw.one_besar);
    final MediaPlayer duakecik = MediaPlayer.create(this, R.raw.two_kecik);
    final MediaPlayer duabesar = MediaPlayer.create(this, R.raw.two_besar);
    final MediaPlayer tigakecik = MediaPlayer.create(this, R.raw.three_kecik);
    final MediaPlayer tigabesar = MediaPlayer.create(this, R.raw.three_besar);
    final MediaPlayer limakecik = MediaPlayer.create(this, R.raw.five_kecik);
    final MediaPlayer limabesar = MediaPlayer.create(this, R.raw.five_besar);
    final MediaPlayer enamkecik = MediaPlayer.create(this, R.raw.six_kecik);
    final MediaPlayer enambesar = MediaPlayer.create(this, R.raw.six_besar);

    ImageButton satu_kecikIB = (ImageButton) this.findViewById(R.id.satukecikIB);
    ImageButton satu_besarIB = (ImageButton) this.findViewById(R.id.satubesarIB);
    ImageButton dua_kecikIB = (ImageButton) this.findViewById(R.id.duakecikIB);
    ImageButton dua_besarIB = (ImageButton) this.findViewById(R.id.duabesarIB);
    ImageButton tiga_kecikIB = (ImageButton) this.findViewById(R.id.tigakecikIB);
    ImageButton tiga_besarIB = (ImageButton) this.findViewById(R.id.tigabesarIB);
    ImageButton lima_kecikIB = (ImageButton) this.findViewById(R.id.limakecikIB);
    ImageButton lima_besarIB = (ImageButton) this.findViewById(R.id.limabesarIB);
    ImageButton enam_kecikIB = (ImageButton) this.findViewById(R.id.enamkecikIB);
    ImageButton enam_besarIB = (ImageButton) this.findViewById(R.id.enambesarIB);

    satu_kecikIB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            satukecik.start();
        }
    });

    satu_besarIB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            satubesar.start();
        }
    });

    dua_kecikIB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            duakecik.start();
        }
    });

    dua_besarIB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            duabesar.start();
        }
    });

    tiga_kecikIB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            tigakecik.start();
        }
    });

    tiga_besarIB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            tigabesar.start();
        }
    });

    lima_kecikIB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            limakecik.start();
        }
    });

    lima_besarIB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            limabesar.start();
        }
    });

    enam_kecikIB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            enamkecik.start();
        }
    });

    enam_besarIB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            enambesar.start();
        }
    });
