内存不足多个照片上传 [英] out of memory multiple photo upload

问题描述

我想从我的Andr​​oid应用程序上传到服务器几张照片。我得到了内存不足的错误。我的code图像选择如下

I am trying to upload few photos from my android application to the server. I am getting the out of memory error. My code for image selection is as follows

code触发

public void triggerImageSelection(View view) {
    int triggeringView = Integer.parseInt((String) view.getTag());
    Log.v(DBUG, "tag of the view:" + triggeringView);
    Intent intent = new Intent();
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);
    startActivityForResult(Intent.createChooser(intent, "Select Picture"),
            triggeringView);
}

在的onActivityResult code的一部分如下：

---

onActivityResult part of the code is as follows:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);

    Log.v(DBUG, "request code:: " + requestCode);
    switch (requestCode) {
    case 0:
        if (resultCode == RESULT_OK) {
            filePaths[0] = getPath(data.getData());
            File filewe = new File(getPath(data.getData()));
            Bitmap bitmap1 = BitmapFactory.decodeFile(getPath(data
                    .getData()));
            mAdImage1.setImageBitmap(bitmap1);
            if (filewe != null)
                Log.v(DBUG, "got file" + filePaths[0]);
            mAdImage1.setVisibility(View.VISIBLE);

        }

        break;

在的getPath（）;函数返回的文件路径和是如下：

---

the getPath(); function returns the file path and is as follows

private String getPath(Uri uri) {
    String[] projection = { MediaStore.Images.Media.DATA };
    Cursor cursor = getContentResolver().query(uri, projection, null, null,
            null);
    int column_index = cursor
            .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    String filePath = cursor.getString(column_index);
    cursor.close();
    return filePath;
}

我有选择四象四个按钮。它工作正常的第一次，但第二次它显示内存不足的异常。我怎样才能解决这个？

i have four buttons for selecting four images. It works fine for the first time but in second time it shows out of memory exception. How can i tackle with this?

推荐答案

虽然从文件读取尽量减少图象的质量如下

While reading from the file try to reduce the quality of the image as follows

BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 6; 
Bitmap bitmap1 = BitmapFactory.decodeFile(getPath(data.getData()),options); 
mAdImage1.setImageBitmap(bitmap1);
bitmap1.recycle();
bitmap1=null;

如果问题仍然存在，使用的android：largeHeap =真正的清单文件的应用程序标签

If the problem still persists, use android:largeHeap="true" in the application tag of manifest file.
