Question

我不断收到错误消息：

（04-04 23：26：29.557：E / dalvikvm（716）：无法打开堆栈跟踪文件'/data/anr/traces.txt'：权限被拒绝）。

请帮忙。我正在尝试为Android应用程序传递数据。

public class Data extends Activity implements OnClickListener{
Button start, startFor;
EditText sendET;
TextView gotAnswer;
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.get);
    initialize();

}
private void initialize(){
    start = (Button) findViewById(R.id.bSA);
    startFor = (Button) findViewById(R.id.bSAFR);
    sendET = (EditText) findViewById(R.id.etSend);
    gotAnswer = (TextView) findViewById(R.id.tvGot); 
    start.setOnClickListener(this);
    startFor.setOnClickListener(this);
}
@Override
public void onClick(View arg0) {
    // TODO Auto-generated method stub
    switch(arg0.getId()){
    case R.id.bSA:
        String bread = sendET.getText().toString();
        Bundle basket = new Bundle();
        basket.putString("key", bread);
        Intent a = new Intent(Data.this,OpenedClass.class);
        a.putExtras(basket);
        startActivity(a);
        break;
    case R.id.bSAFR:
        Intent i = new Intent(Data.this,OpenedClass.class);
        startActivityForResult(i,0);
        break;
    }
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);
}

}

    case R.id.rBoth:

Answer 1

adb shell
root@android: # cd /data/anr
root@android:/data/anr # ls -l traces.txt
-rw-rw-rw- system   system      76808 2013-04-05 13:03 traces.txt
root@android:/data/anr #

-rw-rw-rw是你应该看到的（它意味着读写权限）

如果您看到不同的内容，请执行

root@android:/data/anr # chmod 666 traces.txt

PS您的设备必须是root用户，否则您将无法解决此问题：）
