我正在尝试根据列表中的数据生成.txt文件。项目（行）数量至少为10.000。 问题不在文件本身内，因为文件是生成并保存在外部存储器上的，我可以对其进行RUD并通过共享意图共享它，例如通过Gmail。
7000项目的文件大小为aprox 70 KB，但问题是数据包大小为4818144字节，aprox为5 MB？
Lolipop和Marshmallow通过意图共享文件没有任何问题，但是Nougat与失败的BINDER TRANSACTION（包裹大小= 4818133）崩溃JavaBinder TransactionTooLarge异常
我在应用程序选择器中进行选择后发生了崩溃，因此它启动了Gmail，但目前Gmail成为焦点 - ＆gt;应用程序崩溃时提到异常，但文件是附件并且它是有效的（gmail保持焦点，我可以发送文件。
String FILE_PATH = Environment.getExternalStorageDirectory().getPath() + "/" + Constants.INSTANCE.getInventoryFilePath();
private void generateFileTxt(String fileName) {
if (Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState()))
mCanWrite = true;
if (!mCanWrite) {
showDialogWritingError();
this.dismiss();
} else {
String[] data = new String[mProductsList.size()];
StringBuilder sb = new StringBuilder();
String code, count;
String newLine = "\n";
String separator = ";";
try {
for (int i = 0; i < mList.size(); i++) {
if (mList.get(i).getCode() != null) {
code = mList.get(i).getCode();
count = String.valueOf(mCountList.get(i));
sb.append(code).append(separator).append(count).append(newLine);
String row = sb.toString();
data[i] = row;
sb.setLength(0);
}
}
} catch (Exception e) {
Log.e(this.getClass().getSimpleName(), e.toString());
}
try {
File dir = new File(FILE_PATH);
dir.mkdir();
File file = new File(dir + "/" + fileName + mTxtExtension);
file.createNewFile();
FileOutputStream streamOut = new FileOutputStream(file);
OutputStreamWriter streamWriter = new OutputStreamWriter(streamOut);
for (String row : data) streamWriter.append(row);
streamWriter.flush();
streamOut.flush();
streamWriter.close();
streamOut.close();
showDialogShareTxt(fileName + mTxtExtension);
} catch (Exception e) {
Log.e(this.getClass().getSimpleName(), e.toString());
}
}
}
生成文件后启动共享意图的方法：
private void showDialogShareTxt(String fileName) {
Toast.makeText(getActivity(), R.string.toast_file_saved, Toast.LENGTH_SHORT).show();
File file = new File(FILE_PATH + "/" + fileName);
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/*");
intent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://" + file.getAbsolutePath()));
startActivity(Intent.createChooser(intent, "Sending: " + fileName));
}
我（想）我在意图中发送文件名（参考，路径），为什么包裹大小为5MB？ （我知道限制是1MB，或512KB不确定，但这太多了）
