在OutOfMemoryError异常S3星系 [英] OutOfMemoryError in galaxy s3
本文介绍了在OutOfMemoryError异常S3星系的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
意图localIntent =新意图(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
文件DIR =环境
.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
随机=新的随机();
SEQNO = random.nextInt(1000000);
photoName =将String.valueOf(SEQNO);
输出=新的文件(目录,photoName +.JPEG);
imgPath = Uri.fromFile(输出);
localIntent.putExtra(MediaStore.EXTRA_OUTPUT,imgPath);
PATH = output.getAbsolutePath();
startActivityForResult(localIntent,PICK_Camera_IMAGE);
保护无效的onActivityResult(INT申请code,INT结果code,意图数据){
super.onActivityResult(要求code,结果code,数据);
如果(要求code == PICK_Camera_IMAGE&放大器;&安培;结果code == RESULT_OK){
尝试{
文件f =新的文件(路径); 矩阵mat =新的Matrix();
mat.postRotate(90);
//
BMP位图= BitmapFactory.de codeStream(新的FileInputStream(F),NULL,NULL);
位图bmpPic = Bitmap.createBitmap(BMP,0,0,bmp.getWidth(),bmp.getHeight(),凉席,真);
请注意:我用这个code使用相机拍照。它运行在除了三星Galaxy S3每一个设备。当我在S3上运行,它给错误,如OutOfMemoryError错误。

解决方案
您需要使用它之前减少位图的样本大小。这可用于这样做。
私人位图德codeFILE(档案文件)
{
尝试
{
// *********************德code图像尺寸********************
BitmapFactory.Options选项=新BitmapFactory.Options();
options.inJustDe codeBounds = TRUE;
BitmapFactory.de codeStream(新的FileInputStream(文件),空,期权); // **********************找到正确的比例值。它应该是2的幂********************
options.inSampleSize = BitmapConverter.calculateInSampleSize(选件,145,105);
options.inJustDe codeBounds = FALSE; 返回BitmapFactory.de codeStream(新的FileInputStream(文件),空,期权);
}
赶上(FileNotFoundException异常eFileNotFoundException)
{ 返回null;
}
}
然后你就可以调用如果需要Bitmap.recycle(),但我觉得这不会是必要的。
Intent localIntent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
File dir = Environment
.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
random = new Random();
seqNo = random.nextInt(1000000);
photoName = String.valueOf(seqNo);
output = new File(dir, photoName + ".jpeg");
imgPath = Uri.fromFile(output);
localIntent.putExtra(MediaStore.EXTRA_OUTPUT, imgPath);
path = output.getAbsolutePath();
startActivityForResult(localIntent, PICK_Camera_IMAGE);
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode== PICK_Camera_IMAGE && resultCode == RESULT_OK) {
try {
File f = new File(path);
Matrix mat = new Matrix();
mat.postRotate(90);
//
Bitmap bmp = BitmapFactory.decodeStream(new FileInputStream(f), null, null);
Bitmap bmpPic = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(), bmp.getHeight(), mat, true);
Note: i Used this code for taking picture using camera. it runs in every devices except samsung galaxy s3. when i run on s3, it gives error like OutOfMemoryError.

解决方案
You need to reduce the sample size of the bitmap before using it. This can be used to do so.
private Bitmap decodeFile(File file)
{
try
{
//********************* decode image size ********************
BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeStream(new FileInputStream(file), null, options);
// ********************** Find the correct scale value. It should be the power of 2. ********************
options.inSampleSize = BitmapConverter.calculateInSampleSize(options, 145, 105);
options.inJustDecodeBounds = false;
return BitmapFactory.decodeStream(new FileInputStream(file), null, options);
}
catch(FileNotFoundException eFileNotFoundException)
{
return null;
}
}
And then you can call Bitmap.recycle() if required, although I feel that it wouldn't be necessary.
