[英]How to save a non txt file in data/files folder in android
一种将非文本文件保存到 /data/files 文件夹的方法。 如果文件资源来自资产文件夹。
这应该这样做。
private void writeToSDCard() {
try {
File root = Environment.getExternalStorageDirectory();
if (root.canWrite()){
InputStream from = myContext.getResources().openRawResource(rID);
File dir = new java.io.File (root, "pdf");
dir.mkdir();
File writeTo = new File(root, "pdf/" + attachmentName);
FileOutputStream to = new FileOutputStream(writeTo);
byte[] buffer = new byte[4096];
int bytesRead;
while ((bytesRead = from.read(buffer)) != -1)
to.write(buffer, 0, bytesRead); // write
to.close();
from.close();
} else {
Log.d(TAG, "Unable to access SD card.");
}
} catch (Exception e) {
Log.d(TAG, "writeToSDCard: " + e.getMessage());
}
}
}
