Android根据姓名来查找电话问题

大家好！刚学Android，刚写了一个根据姓名来查找电话的小程序，有如下问题，希望各位指导一下，谢谢，麻烦说的详细一点，再次感谢。
问题（logcat）：

1、Can't open keycharmap file
2、Error loading keycharmap file '/system/usr/keychars/cyttsp-i2c.kcm.bin'. hw.keyboards.65542.devname='cyttsp-i2c'
3、Using default keymap: /system/usr/keychars/qwerty.kcm.bin

代码：

public class MainActivity extends Activity {
    private Button b1;
    private EditText myEditText;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
         b1 = (Button)findViewById(R.id.Button01);

         myEditText = (EditText)findViewById(R.id.EditText01);
         b1.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                 String name = myEditText.getText().toString();
                 Bundle data = new Bundle();
                 data.putString("name", name);

                 Intent intent = new Intent(MainActivity.this,ResultActivity.class);
                 intent.putExtras(data);
                 startActivity(intent);
            }
        });

    }
}

public class ResultActivity extends Activity {

解决方案

现在正在学习 过来顶一个 不错哦！继续努力加油！

解决方案二：

我遇到过这样的问题

Android：label的值必须是字符串资源，不可以是硬编码字符串。

解决方案三：

路过！学理的就是好呀
