Android 致命信号6 SIGABRT代码=-6

我正在写一个android程序来可视化音频信号。主要活动是：

package com.example.soundvisualizer;
import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.util.Log;
import android.view.Display;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends Activity implements OnClickListener {
private CDrawer.CDrawThread mDrawThread;
private CDrawer mdrawer;
private Button btn;
private View.OnClickListener listener;
private Boolean m_bStart;
private Boolean recording;
private CSampler sampler;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    m_bStart = false;
    mdrawer = (CDrawer) findViewById(R.id.drawer);
    while (true){
        recording = false;
        run();    
        return; 
    }  
}

/**
 * Pause the visualizer when the app is paused
 */
@Override
protected void onPause(){
    System.out.println("onPause");
    sampler.SetRun(false);
    mDrawThread.setRun(false);
    sampler.SetSleeping(true);
    mDrawThread.SetSleeping(true);
    super.onPause();
}
/**
 * Resters the visualizer when the app restarts
 */
@Override
protected void onRestart(){
    m_bStart = true;
    System.out.println("onRestart");
    super.onRestart();
}
/**
 * Resume the visualizer when the app resumes
 */
@Override
protected void onResume(){
    System.out.println("onResume");
    int i = 0;
    while (true){
        if ((sampler.GetDead2()) && (mdrawer.GetDead2())){
            System.out.println(sampler.GetDead2() + ", " + mdrawer.GetDead2());
            sampler.Restart();
            if (!m_bStart.booleanValue())
                mdrawer.Restart(true);
            sampler.SetSleeping(false);
            mDrawThread.SetSleeping(false);
            m_bStart = false;
            super.onResume();
            return;
        }
        try{
            Thread.sleep(500L);
            System.out.println("Hang on..");
            i++;
            if (!sampler.GetDead2().booleanValue())
                System.out.println("sampler not DEAD!!!");
            if (!mdrawer.GetDead2().booleanValue()){
                System.out.println("mDrawer not DeAD!!");
                mdrawer.SetRun(false);
            }
            if (i <= 4)
                continue;
            mDrawThread.SetDead2(true);
        }
        catch (InterruptedException localInterruptedException){
            localInterruptedException.printStackTrace();
        }
    }   
}

@Override
protected void onStart(){
    System.out.println("onStart");
    super.onStart();
}

@Override
protected void onStop(){
    System.out.println("onStop");
    super.onStop();
}


/** 
 * Recives the buffert from the sampler
 * @param buffert
 */
public void setBuffer(short[] paramArrayOfShort){
    mDrawThread = mdrawer.getThread();
    mDrawThread.setBuffer(paramArrayOfShort);
}

/**
 * Called by OnCreate to get everything up and running
 */
public void run(){
    try {
        if (mDrawThread == null){
            mDrawThread = mdrawer.getThread();
        }
        if (sampler == null)
            sampler = new CSampler(this);
        Context localContext = getApplicationContext();
        Display localDisplay = getWindowManager().getDefaultDisplay();
        Toast localToast = Toast.makeText(localContext, "Please make some noise..", Toast.LENGTH_LONG);
        localToast.show();
        if (sampler != null){
            try {
                sampler.Init();
            } 
            catch (Exception e) {
                Toast.makeText(this,"Could not instance the sampler. Could not access the device audio-drivers", Toast.LENGTH_LONG).show();
            }
            btn = (Button) this.findViewById(R.id.button_stop);
            btn.setOnClickListener(this);
            sampler.StartRecording();
            sampler.StartSampling();
        }
      }
    catch (NullPointerException e) {
        Log.e("Main_Run", "NullPointer: " + e.getMessage());
    }
}

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    if(btn.getText().equals("Start")){
        btn.setText("Stop");
        sampler.StartRecording();
        sampler.StartSampling();
    }
    else{
        btn.setText("Start");
        sampler.StopRecording();
    }
}

}

我不知道是什么原因导致了错误以及如何修复它。有人能帮我吗？ 提前谢谢

我发现其中解释了sigabrt是什么类型的错误。表中显示sigabrt可以通过使用-Xrs禁用。如何在Eclipse IDE中使用-Xrs？？？

在本例中发生的情况：

• 我在创建时加载一个视图，并在调用函数后快速访问该视图

视图在某个瞬间可以为空

在您的情况下，请在每次访问该视图时放置以下内容：

if(mdrawer!=null){
   //DO Whatever
}else{
   Log.e(TAG,"ANDROID BUG");
}

EDIT：我意识到这不是因为函数调用得非常快。这是因为我有一个侦听器，并且在OnDestroy（）时没有注销。当OnCreate时，我有两个监听器。一个结果为空，另一个结果为OK。

@Override
public void onDestroy() {                       
    super.onDestroy();
    if (mSensorManager!=null){mSensorManager.unregisterListener(listener);}
}

您需要发布一个更完整的堆栈跟踪，这样我们才能看到实际的问题所在。@ChrisStratton我用LogCat的屏幕截图编辑了这篇文章。就这些。我不知道问题出在哪里。使用命令行logcat工具，您应该可以从这样的错误中捕获大约一百行信息。不要发布截图，而是复制并粘贴实际文本。@ChrisStratton我刚刚用logcat行编辑了文章。你绝对不应该做的一件事是在UI线程事件方法中睡眠半秒钟！

@Override
public void onDestroy() {                       
    super.onDestroy();
    if (mSensorManager!=null){mSensorManager.unregisterListener(listener);}
}
