android - 应用程序运行良好，现在由于看似未知的原因而中断

Question

根据 this问题，我的应用程序抛出看似随机的错误。每当我添加重大更改(新资源、新代码、函数调用)等时，运行良好的代码就会开始崩溃。 Activity 根本不会启动。 logcat 输出告诉我 XML 文件有错误。不幸的是，我没有碰过那个文件。仔细观察它，它还告诉我一些关于在动画 XML 文件中找不到的颜色资源的信息。 logcat 输出连同代码如下:

时钟 View :

package uris.apps.com;

import android.content.Context;
import android.content.res.Resources;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.util.AttributeSet;
import android.widget.TextView;

    private long startTime;
    private float secs;

    super(context, ats, ds);
    init();
    }

    public ClockTextView (Context context) {
    super(context);
    init();
    }

    public ClockTextView (Context context, AttributeSet attrs) {
    super(context, attrs);
    init();
    }

    public void initStartTime() {
    startTime = SystemClock.uptimeMillis();
    }

    private void init() {
    // Get a reference to our resource table.
    Resources myResources = getResources();

    // Create the paint brushes we will use in the onDraw method.
    textPaintColor = new Paint(Paint.ANTI_ALIAS_FLAG);
    textPaintColor.setColor(myResources.getColor(R.color.clockTextColor));
    textPaintColor.setTextSize( 50 );

    startTime = SystemClock.uptimeMillis();

    // // Get the paper background color and the margin width.
    // paperColor = myResources.getColor(R.color.notepad_paper);
    //margin = myResources.getDimension(R.dimen.notepad_margin);
    }

    public float getRunningTime() {
    return secs;
    }

    @Override
    public void onDraw(Canvas canvas) {

    //number of milliseconds elapsed
    long curTime = SystemClock.uptimeMillis() - startTime;
    //convert to seconds
    secs = curTime / 1000.0f;
    //Round to 1 decimal place
    //float p = (float) Math.pow(10,1);
    secs = (float) (Math.round(secs*10.0f)/10.0f);

    canvas.drawText(String.valueOf(secs), 60, 60, textPaintColor);
    // Color as paper
    // canvas.drawColor(paperColor);

    // // Draw ruled lines
    // canvas.drawLine(0, 0, getMeasuredHeight(), 0, linePaint);
    // canvas.drawLine(0, getMeasuredHeight(), 
    //                    getMeasuredWidth(), getMeasuredHeight(), 
    //                    linePaint);

    // // Draw margin
    // canvas.drawLine(margin, 0, margin, getMeasuredHeight(), marginPaint);

    // // Move the text across from the margin
    // canvas.save();
    // canvas.translate(margin, 0);

    // Use the TextView to render the text.
    super.onDraw(canvas);
    //canvas.restore();
    invalidate();
    }
}

最后是定义时钟颜色的资源:

<?xml version="1.0" encoding="utf-8"?>

<resources>
  <color name="clockTextColor">#FFFFFF</color>
</resources>

感谢 CommonsWare。 XML 以某种方式不同步。可能是因为我没有使用 Eclipse。无论如何，解决方法是删除 bin 目录，重新编译并安装。
