嗨朋友我在安装我的应用时遇到问题。
我是android编程的初学者。我构建了一个程序来获取位置并将其与我在代码中给出的位置进行比较。但是执行它时没有显示任何内容，应用程序会自动关闭。我正在粘贴代码和LOGCAT。我无法找到错误。
作为一个初学者，我很难找到错误。所以论坛是我最后的希望，我希望那里的人肯定会帮助我解决这个问题。
public class MainActivity extends ActionBarActivity {
public EditText text1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
text1 =(EditText) findViewById(R.id.text1);
Intent intent = new Intent(this, TrackService.class);
startService(intent);
}
@Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
finish();
}
}
我怀疑我的manifest.xml存在一些问题...我不知道它只是一个猜测...如果有人帮我解决这个问题会很好... TY
