ANR检测

ANR检测工具类

public class ANRWatchDog extends Thread { public static final int MESSAGE_WATCHDOG_TIME_TICK = 0; /** * 判定Activity发生了ANR的时间，必须要小于5秒，否则等弹出ANR，可能就被用户立即杀死了。 */ public static final int ACTIVITY_ANR_TIMEOUT = 2000; private static int lastTimeTick = -1; private static int timeTick = 0; private Handler watchDogHandler = new android.os.Handler() { @Override public void handleMessage(Message msg) { timeTick++; timeTick = timeTick % Integer.MAX_VALUE; } }; @Override public void run() { while (true) { watchDogHandler.sendEmptyMessage(MESSAGE_WATCHDOG_TIME_TICK); try { Thread.sleep(ACTIVITY_ANR_TIMEOUT); } catch (InterruptedException e) { e.printStackTrace(); } //如果相等，说明过了ACTIVITY_ANR_TIMEOUT的时间后watchDogHandler仍没有处理消息，已经ANR了 if (timeTick == lastTimeTick) { throw new ANRException(); } else { lastTimeTick = timeTick; } } }}

public class ANRException extends RuntimeException { public ANRException() { super("应用程序无响应，快来改BUG啊！！"); Thread mainThread = Looper.getMainLooper().getThread(); setStackTrace(mainThread.getStackTrace()); }}
