当我运行猴子测试时，发现了 ANR。查看 /data/anr 中的 anr 日志，发现 NotifiThread（在 MyService 中定义）中的代码可能会导致 ANR：
Thread.sleep(Util.getIntervalTime(getBaseContext())); //(the first one in detail code).
问题是代码在子线程中运行（NotifiThread不是由Handler.post（Runnable）调用而是由new Thread().start()调用的）。为什么我会得到 ANR。有人可以就这种情况给一些建议吗，谢谢。以下是详细代码和 ANR 日志。
详细代码：
public class MyService extends Service {
部分省略.....
class NotifiThread extends Thread {
public void run() {
while (isAvailable) {
try {
String json = null;
json = new HttpActions(getBaseContext()).getPushNotification(getApplicationContext());
if (null != json && json.length() > 0) {
JSONObject jsonObject = new JSONObject(json);
int code = jsonObject.getInt("code");
String msg = jsonObject.getString("msg");
if (0 == code) {
if (!jsonObject.isNull("info")) {
JSONArray ja = jsonObject.getJSONArray("info");
for (int i = 0; i < ja.length(); i++) {
String item = ja.getJSONObject(i).toString();
ULog.d(TAG, "Receive a pushMessage: " + item);
if (!TextUtils.isEmpty(item)) {
final Message mymsg = new Message();
mymsg.what = NotifyHandlerProvider.HANDLER_SET_STATUES_BAR;
mymsg.obj = item;
handlerProvider.handleMessage(mymsg);
}
}
}
}
else {
ULog.i(TAG, json.toString());
}
}
ULog.i(TAG, "intervale Time -->"+Util.getIntervalTime(getBaseContext()));
Thread.sleep(Util.getIntervalTime(getBaseContext())); /////////here may be cause anr
// Thread.sleep(30000); //test time 30Sec
} catch (InterruptedException e) {
ULog.e(TAG, e.getMessage());
e.printStackTrace();
} catch (TVException e) {
try {
ULog.i(TAG, "intervale Time -->"+Util.getIntervalTime(getBaseContext()));
Thread.sleep(Util.getIntervalTime(getBaseContext()));
// Thread.sleep(30000); //test time 30S
} catch (InterruptedException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
ULog.e(TAG, e.getMessage());
e.printStackTrace();
} catch (JSONException e) {
ULog.e(TAG, e.getMessage());
e.printStackTrace();
}
}
};
}
