java应用程序导致设备运行缓慢

Question

我最近听说了Butterknife api，所以我决定制作一个小益智应用程序来熟悉它。然而，当我尝试运行代码时，会出现一个通知，告诉我该应用程序导致我的手机运行缓慢，并且它会在不给出错误堆栈的情况下耗尽我设备的内存。有人能告诉我这有什么问题吗

主要活动。java

public class MainActivity extends AppCompatActivity {
Context context = getApplicationContext();
CharSequence text = "It's ALIVE!!";
int duration = Toast.LENGTH_SHORT;

@Bind(R.id.button_main_one) Button button;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ButterKnife.bind(this);
}

@OnClick(R.id.button_main_one)
public void button_clicked()
{
    Toast toast = Toast.makeText(context,text, duration);
}

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

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}}

主要活动。xml
