Question

我有一个Android应用程序，有很多图像。它适用于除2.3之外的所有最新版本的android。这是我的代码：

if (mBitmap != null) {
            mBitmap.recycle();
            mBitmap = null;
        }

        //mBitmap = Bitmap.createBitmap(480, 800, Bitmap.Config.ARGB_8888);
        mBitmap = Bitmap.createBitmap(320, 480, Bitmap.Config.ARGB_4444);                                                         

        mPath = new Path();
        mBitmapPaint = new Paint(Paint.DITHER_FLAG);

        mRealPaint = new Paint();
        mRealPaint.setAntiAlias(true);
        mRealPaint.setDither(true);
        mRealPaint.setColor(Color.BLACK);
        mRealPaint.setStyle(Paint.Style.STROKE);
        mRealPaint.setStrokeJoin(Paint.Join.BEVEL);
        mRealPaint.setStrokeCap(Paint.Cap.ROUND);
        mRealPaint.setStrokeWidth(12);

这是stacktrace：

有人可以指导我在这方面做错了吗？

Answer 1

“大部分”姜饼设备的堆大小较低，因此除非您缩小位图大小，否则您的应用会崩溃。 inSampleSize = 6和bove;旧设备首选。甚至像“HTC”品牌这样的新设备，堆大小仍然很低，因此您的应用程序将崩溃。我在做什么。如果用户手机堆大小很低，我会降低图像质量，以避免内存不足问题。

仅在Android 2.3上出现内存不足
