我在我的应用程序中使用了crashylytics。它已经投入生产约2个月。我有一些崩溃，我已经能够解决，但最近几天我得到一个堆栈跟踪，这并没有指向我的代码（甚至活动）中的一行，此时崩溃发生。

通常在崩溃中我找到一行
at com.justmedit.datatrix.MainActivity$1.done(MainActivity.java:90)
这指向导致崩溃的线。 有人可以告诉我为什么会发生这种情况或可能性，以便我可以调查这个并在下一个版本中修复它。谢谢！
添加了我用于缩放位图的代码 -
public Bitmap ScaleImage( String value, float dimension){
Bitmap bitmap = BitmapFactory.decodeFile(value);
int width = bitmap.getWidth();
int height = bitmap.getHeight();
float scale;
if (width>height){scale=dimension/width;}
else {scale=dimension/height;}
ExifInterface exif;
Matrix matrix = new Matrix();
try {
exif = new ExifInterface(value);
int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 0);
Log.d("EXIF", "Exif: " + orientation);
if (orientation == 6) {
matrix.postRotate(90);
Log.d("EXIF", "Exif: " + orientation);
} else if (orientation == 3) {
matrix.postRotate(180);
Log.d("EXIF", "Exif: " + orientation);
} else if (orientation == 8) {
matrix.postRotate(270);
Log.d("EXIF", "Exif: " + orientation);}
}catch (IOException e){e.printStackTrace();}
matrix.postScale(scale, scale);
Bitmap resizedBitmap = Bitmap.createBitmap(bitmap, 0, 0,width, height, matrix, true);
return resizedBitmap;
}
这让我可以传递SD卡上图像的位置和一个浮点数，它可以在图像重新缩放后确定最大尺寸的尺寸。
答案 0 :(得分：1)
您必须以样本大小创建位图。看看Loading bitmaps efficiently。
public static int calculateInSampleSize(
BitmapFactory.Options options, int reqWidth, int reqHeight) {
// Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
int inSampleSize = 1;
if (height > reqHeight || width > reqWidth) {
if (width > height) {
inSampleSize = Math.round((float) height
/ (float) reqHeight);
} else {
inSampleSize = Math.round((float) width / (float) reqWidth);
}
}
return inSampleSize;
}
以下方法将解码Bitmap数组中的样本量Byte。
public static Bitmap decodeSampledBitmapFromBytes(byte[] bytes, int reqWidth,
int reqHeight) {
Bitmap bm = null;
// First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeByteArray(bytes, 0, bytes.length, options);
// Calculate inSampleSize
options.inSampleSize = calculateInSampleSize(options, reqWidth,
reqHeight);
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
bm = BitmapFactory.decodeByteArray(bytes, 0, bytes.length, options);
return bm;
}
public static int calculateInSampleSize(
BitmapFactory.Options options, int reqWidth, int reqHeight) {
// Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
int inSampleSize = 1;
if (height > reqHeight || width > reqWidth) {
if (width > height) {
inSampleSize = Math.round((float) height
/ (float) reqHeight);
} else {
inSampleSize = Math.round((float) width / (float) reqWidth);
}
}
return inSampleSize;
}
100是高度和宽度，您可以根据需要进行修改。
Bitmap bitmap = decodeSampledBitmapFromBytes(bytes, 100, 100);
希望它会有所帮助。！
