一段时间后，Android App崩溃了

Question

我有一个问题，我对导致崩溃的原因一无所知。 我有一个Timer内部类，它每分钟从MainActivity onCreate()触发一次。

timer = new Timer(); 
timer.scheduleAtFixedRate(new RemindTask(),2000, 10000);

这是我的Timer类。此计时器类负责启动另一个活动。

class RemindTask extends TimerTask {

public CaptureActivityHandler cah = new CaptureActivityHandler();
public void run() {
    Log.d("TIMER",  "timer is triggered");
    TimerCount++;

    if(TimerCount > 1)
    {
        Log.d("TIMER",  "TimerCount > 1");
        boolean flag = cah.getDecodeFlag();

        if(flag){
            Log.d("TIMER",  "decodeFlag true");
            cah.setDecodeFlag(false);
            Intent intent = new Intent(MainActivity.this,CaptureActivity.class);
            startActivityForResult(intent,SCAN_QRCODE_REQUEST);
        }
        else
        {
            Intent intent = new Intent(MainActivity.this,CaptureActivity.class);
            startActivityForResult(intent,SCAN_QRCODE_REQUEST);
        }
    }
    else {
        Intent intent = new Intent(MainActivity.this,CaptureActivity.class);
        startActivityForResult(intent,SCAN_QRCODE_REQUEST);
    }
   }
}

问题是该应用在15小时后崩溃了。 Logcat显示：

然后考虑到它可能是由内存泄漏引起的，然后我将计时器周期缩短为10秒。 不出所料，它在2.5小时后崩溃了。

但是，似乎不太可能是因为内存，因为使用的堆大小始终约为58％。 此外，内存使用率约为4％，占设备内存总量100％的3500万。

这是清单。

是否想到可能导致崩溃的原因？

Answer 1

不是实际的答案，但您应该将run()方法更改为此。

public void run() {
    Log.d("TIMER",  "timer is triggered");
    TimerCount++;

    if (TimerCount > 1) {
        Log.d("TIMER",  "TimerCount > 1");
        boolean flag = cah.getDecodeFlag();

        if(flag){
            Log.d("TIMER",  "decodeFlag true");
            cah.setDecodeFlag(false);
        }
    }

    Intent intent = new Intent(MainActivity.this,CaptureActivity.class);
            startActivityForResult(intent,SCAN_QRCODE_REQUEST);

}

它做的完全相同，只是重复次数更少。

Answer 2

异常显示为“ java.lang.SecurityException：不允许启动活动意图{cmp = com.handalindah.manjalinkkiosk / tw.com.quickmark.sdk.CaptureActivity}”。

某些运行后，tw.com.quickmark.sdk.CaptureActivity是否未注册？
