无法呼叫活动

Question

我想从菜单调用一个活动，但当我按下按钮调用调谐器活动时，应用程序就退出了。当呼叫另一个活动成功时

这是调谐器活动

public class TunerActivity extends AppCompatActivity {
    private static final String TAG = TunerActivity.class.getSimpleName();
    private TunerFragment tunerFragment;
    private PitchFragment pitchFragment;
    private boolean showCancel;

    @Override
    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        showCancel = false;
        setContentView(R.layout.tuner_activity);
        Toolbar toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        tunerFragment = new TunerFragment();
        getSupportFragmentManager().beginTransaction().add(R.id.fragment_container, tunerFragment, TunerFragment.TAG).commit();
        setTimedNotification();
    }
    ....
}

这是仪表板活动（菜单）

public class DashboardActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.dashboard_layout);


        // Dashboard Tombol berita
        Button btn_tuner = (Button) findViewById(R.id.btn_tuner);

        // Dashboard Tombol teman
        Button btn_midi = (Button) findViewById(R.id.btn_midi);

        // Dashboard Tombol info
        Button btn_info = (Button) findViewById(R.id.btn_info);

        // Dashboard Tombol helo
        Button btn_help = (Button) findViewById(R.id.btn_help);


        // Menangkap klik event tombol tuner

        btn_tuner.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View view) {
                // Menampilkan screen berita
                Intent i = new Intent(DashboardActivity.this, TunerActivity.class);
                startActivity(i);
            }
        });

       // Menangkap klik event tombol teman
        btn_midi.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View view) {
                // Menampilkan screen teman
                Intent i = new Intent(getApplicationContext(), TemanActivity.class);
                startActivity(i);
            }
        });

        // Menangkap klik event tombol pesan
        btn_info.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View view) {
                // Menampilkan screen pesan
                Intent i = new Intent(getApplicationContext(), PesanActivity.class);
                startActivity(i);
            }
        });

        // Menangkap klik event tombol tempat
        btn_help.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View view) {
                // Menampilkan screen tempat
                Intent i = new Intent(getApplicationContext(), TempatActivity.class);
                startActivity(i);
            }
        });

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.dashboard, menu);
        return true;
    }

}

这是清单 我被宣布为所有活动
