我正在尝试将数据库从assets文件夹复制到设备上。这段代码在模拟器和已root设备上都能正常工作。我想知道在未root设备上是否会出现任何问题,或者它会同样工作。
private void StoreDatabase() {
File DbFile = new File(
"data/data/packagename/DBname.sqlite");
if (DbFile.exists()) {
System.out.println("file already exist ,No need to Create");
} else {
try {
DbFile.createNewFile();
System.out.println("File Created successfully");
InputStream is = this.getAssets().open("DBname.sqlite");
FileOutputStream fos = new FileOutputStream(DbFile);
byte[] buffer = new byte[1024];
int length = 0;
while ((length = is.read(buffer)) > 0) {
fos.write(buffer, 0, length);
}
System.out.println("File succesfully placed on sdcard");
// Close the streams
fos.flush();
fos.close();
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
